730nm far-red light's shade avoidance effect

Everything you need to know about LED grow lights

What type of light do plant grow need?

Plants’ demand for light is mainly embodied in three aspects of light radiance (intensity), photoperiod, and spectral distribution, which is also called the “light environment” for plant growth.
Compared with traditional plant grow lights (fluorescent lamps and high-pressure sodium lamps), LEDs can adjust the spectrum and radiation intensity according to needs. Secondly, LEDs are cold light sources that can illuminate plants at close range without causing burns; again, LED light sources The small size helps reduce the height of the cultivation layer and increase the cultivation density per unit space. Therefore, LED grow lights technology has been widely used in the field of agricultural lighting.

Artificial light environment lighting design elements

Photon flux density (PPFD, unit: μmol/s/m2): The number of light quanta per unit leaf area per unit time, which is consistent with the unit of photosynthesis rate and has a great impact on plant biomass and its growth rate influences.
Through the spectral distribution, the morphology and color of certain genotypes can be effectively adjusted.
The flowering time of some short-day and long-day plants can be effectively controlled by photoperiod or light duration.

These parameters are not independent or unique, but all these factors work together to regulate the overall growth of plants.

It is well known that factors such as temperature, humidity, root zone temperature, wind, moisture, nutrients, and oxygen/carbon dioxide levels play an important role in regulating plant growth. In addition to these factors, the light also plays an important role in the growth cycle of plants. Since the start of cultivation, all varieties of crops, flowers, and herbs have been cultivated in the sun. Therefore, the intensity, spectrum, and duration of sunlight affect their morphology, growth, and flowering in a natural way.

Plant biomass, morphology and flowering times can be controlled by regulating the light quantity, quality and duration

 

Grow lights vs Human-centric lighting

For humans, light reacts with the short, medium, and long photoreceptors in the eyes, allowing us to see colors. For plants, light reacts with chlorophyll and plant pigments to promote growth. For example, the chlorophyll absorption curve is mainly responsible for photosynthesis to promote plant growth. Plant pigments are sensors of plants that respond to the environment and adjust their shape.

The metrics of human vision cannot be applied to plant lighting because the lighting indicators of plants are essentially based on photons. For example, photon flux (PF) measures the number of photons emitted from a light source in μmol/s, while photon flux density (PFD) measures the number of photons reaching plants. Unless artificial LED lights are also used as conventional lighting sources, color attributes such as color rendering index (CRI) and correlated color temperature (CCT) are no longer relevant for plant lighting.

Grow lights vs Human-centric lighting

The absorption curves of plants are not the same as for the human eye. Different spectrum and metrics are necessary to quantify horticultural lighting

 

Plant photosynthesis & chlorophyll

Plants convert light energy into chemical energy through photosynthesis.
Photosynthesis principle: Green plants have the ability of photosynthesis-with the help of light energy and chlorophyll, under the catalysis of enzymes, water, inorganic salts and carbon dioxide are used for photosynthesis, releasing oxygen, absorbing carbon dioxide, and producing organic substances such as glucose , For plant use. Among them, chlorophyll a and b have the highest absorption rate in the blue and red wavelength regions. Therefore, blue light 450nm and red light 660nm promote plant biomass and growth rate.

PAR absorption curves for chlorophyll A and B
Photomorphogenesis: The process of forming the morphological structure of plant organs under light conditions. In order to be able to perceive the light intensity, light quality, light direction and photoperiod of the surrounding environment and respond to its changes, plants have evolved a photoreceptor system (photoreceptor). The photoreceptor is the key for plants to sense changes in the external environment. The main photoreceptor in the photoreaction of plants is phytochrome.
The photosensitizing pigments in plants exist in two relatively stable states: red light absorption type (Pr, lmax=660nm) and far-red light absorption type (Pfr, lmax=730nm). Phytochrome is a pigment protein that participates in photomorphogenesis and regulates plant development, and plays an important role in the entire growth and development process of plants from germination to maturity.

Plant photomorphogenesis & phytochrome

If the plant is only irradiated by the deep red light of 660nm, the plant will feel that it is under direct sunlight and grow normally. And if the plant is mainly irradiated by the far-red light of 730nm, the plant will feel as if it is blocked by another taller plant from the direct light of the sun, so the plant will grow harder to break through the obscuration. Helping plants grow taller does not mean that there will be more biomass (biomass).

Plant photoperiod regulation & phytochrome

Photoperiod (Photoperiod): The natural or artificial cycle in which the day and night faced by organisms alternate. Note: The photoperiod is a daily cycle, that is, 24h.
Light period: The period of light in the day-night light-dark cycle.
Dark period: The period of darkness in the light-dark cycle of day and night.

The light morphogenesis effect is regulated by applying a spectrum with a specific mix of 660nm and 730nm. Controlling the flowering cycle, without relying only on the influence of the season, is of great value for ornamental flowers.
The conversion of the phytochrome Pr to Pfr is mainly induced by the deep red light of 660nm (representing the sunlight during the day), while the conversion of Pfr to Pr usually occurs naturally at night, and it can also be excited by 730nm far-red light, as shown in the figure Shown. It is generally believed that the control of plant flowering by phytochrome mainly depends on the ratio of Pfr/Pr. Therefore, we can control the value of Pfr/Pr through 730 nm far-red light irradiation to more precisely control the flowering cycle.

LED grow lights applications

•Top lighting
•Inter lighting
•Vertical farming or multilayer cultivation
•Consumer products

 

Top lighting

The plants are illuminated from above similar to sunlight. The aim is to supplement natural daylight and raise growth light levels in order to
enhance photosynthesis and thereby improve the growth and quality of plants in greenhouses. Additional top lighting is already common with conventional light sources such as high-pressure sodium (HPS). The heavy power consumption and the heat of the HPS
luminaires make a large distance between the light source and the plants necessary. The photon flux of conventional luminaires can be up to 2000 μmol/s. LED luminaires do not usually provide a similar high photon flux from one luminaire but from several, more distributed luminaires with lower photon flux. The photon flux per luminaire may change significantly depending on the luminaire setup.

Inter lighting

Using LEDs as a light source is a perfect solution to enable inter lighting. In this case the light sources are placed in between the plants
and the leaves. This reduces the shade of the leaves which may result from top lighting and thus increase the amount of light even on the
lower leaves. Unlike with hot HPS luminaires, the low temperatures of the LED luminaire do not cause any damage to the plants. Inter
lighting is considered as supplemental lighting since the LED lighting is typically used in greenhouses in addition to natural daylight.

Vertical farming

In vertical farms, plant factories or multi-layer cultivation applications the crop is grown in layer one on top of each other. The light is placed directly above and in close proximity of the crop. This only allows “cold” light sources such as LED luminaires to ensure that the plants are not burned by the high temperature of the light source. Uniform illumination is necessary in order to achieve the even growth of the crop over the complete plant area.Due to the stacking of plant layers the plants grow completely under artificial light without any daylight at all. This is also referred to as sole-source lighting. This gives complete control over the timing, amount and spectral composition but also requires a complete light content. If people work under these lighting conditions a white light impression is necessary to enable the workers to assess the quality of the plants.

Consumer products

Consumer horticultural lighting – Grow Bulbs:
The grow bulbs can be used in various nonprofessional applications. The target is not primarily the rapid growth of the biomass but mainly to maintain and grow the plant under low light indoor conditions. In addition, a pleasant impression is preferred. Various white LEDs in different converter mixes are used for this purpose.
Consumer horticultural lighting – Grow Boxes: Grow Boxes address the lifestyle trend of home growing. Here the plants are grown completely under artificial light and under controlled conditions. The flexibility to adjust the spectrum and the lighting conditions to the different products is the key to this application. A broad range of various LEDs with different wavelengths is used to provide exactly the right lighting recipe for the illuminated product. Due to the new application and the significantly different setups and shapes, a typical value or setup cannot yet be determined.

Only the planting process can reflect the LED grow lights effect

LED grow lights are developed based on the planting process, not just spectroscopy.

Before that, I talked more about the spectrum technology of LED grow lights and the parameters of light quantum. This is a necessary condition for LED grow lights to enter the greenhouse to fill light and plant factories. However, what are the sufficient conditions for planting under an artificial light environment? What determines the planting effect and planting efficiency?
It is greenhouse gardening. In the industrialization process of plant planting, we call it the planting process. In the case of insufficient sunlight in the greenhouse, supplementary light is inevitable. The spectral parameters of the plant light meet the spectral design requirements, which may not guarantee the planting effect and Efficiency. In the artificial light environment, the planting process is the core technology. The planting process is a sufficient condition for planting in the artificial environment. Under the premise of the planting process, the spectral parameters of the plant light can reflect the planting effect and planting efficiency.
If the LEDs packaged by any two packaging companies have the same spectral parameters, the planting effect is the same under the same plant canopy PPFD and the same planting process. It has nothing to do with the brand of the LEDs packaging company. The most taboo of bio-optics is to People’s preference for LEDs brands is superimposed on spectral technology, which is a taboo.

plant

What needs to be acknowledged is that in lighting products, the brand effect of LEDs will enhance customers’ sense of identity. That’s because the lighting is a solution to human visual problems. People are accustomed to subconsciously preferring LEDs brands that superimpose lighting products. This subconsciousness also improves purchase The pride and comfort of the self-feeling.

But, plants will not respond to the brand of LEDs, only the spectral parameters of LEDs; people’s brand preference must not be superimposed on the application of plant lights. Unfortunately, many plant light manufacturers (including beginners in plant cultivation) put too much energy on the brand of LEDs, so that they forget the magic in the substrate and nutrients, and forget the priority of the ability to control the planting environment parameters. Sexuality, forgetting that horticulture is a complex professional discipline, entering into the mode of thinking of only spectral parameter theory, ignoring what is the core technology of plant cultivation.

Only the spectral parameter theory only shows the lack of knowledge of planting technology.

My suggestion is to use LEDs with excellent cost performance and focus on cultivation medium deployment and high-quality genetics. The effect of spending money on planting technology is far better than spending on plant grow light. This is my advice. Spectral parametric thinking traps itself in the accusation that it cannot solve the customer’s planting effect.
Recently, the phenomenon that a certain brand of LEDs needs to wait in line for supply is really incredible. You can consult professionals in the horticulture discipline, listen to their ideas, and become a plant grow lights company, putting the skills of agricultural professionals second. You have already lost the first step.

There are three principles of spectroscopy technology:

1. There is no best spectrum, only the most suitable.

2. Light quantity has priority over light quality.s

3. With the same planting effect, the less the spectral components, the higher the photosynthetic efficiency of the spectral design.

LED grow light spectroscopy technology is in continuous development, grow lights can practice new high-efficiency spectroscopy technology every year, that is to say, the technical cycle for improving the photosynthetic efficiency of plants with spectroscopy design is less than one year, and good spectroscopy design will ultimately serve the cultivation Cost, plant cultivation usually does not reflect the performance and quality of similar industrial products. The price is the dominant factor. The price increase in cannabis grow lights is not equivalent to the yield and quality of plants. The increase in yield and quality can be more easily obtained through the planting process and does not require excessive investment.

The spectral parameters of Grow lights can be considered from the following aspects:

1. The QE value of domestic LEDs for plants has reached or exceeded foreign lamp beads, and the cost performance is excellent.

2. Choose lamp beads whose junction voltage is lower than 3.0V to reduce power consumption.

3. Learn to reduce the drive current to obtain high QE, and the effect is obvious.

4. Put the priority of planting technology before grow lights at any time to reduce blindness.

5. The QE of LED Grow lights is greater than 2.2umol/J, and its planting effect and efficiency basically depend on the planting process. This is expert thinking.

6. Know how to use the radiation heat transfer mechanism to control the PPFD of the plant canopy. This technology needs to be studied again, and its effect is much better than blindly increasing the QE value of LED grow lights.

7. The comprehensive energy-saving technology is better than the improvement of the energy efficiency of the lamps, and the reduction of planting costs is the development direction of LED grow lights.

The LED grow lights spectrum technology aims to serve the planting process. Without the goal of planting technology, the LED grow lights spectrum design is not a technology.

Finally, someone will raise the issue of the light decay index. Here we need to clarify a limitation. The application of LED grow lights is restricted by the photoperiod. 30,000 hours should meet the light decay index. That is the 5-year working period of grow lights. Spectroscopy technology The improvement cycle of planting efficiency is basically less than one year, just understand this reason.

How To Choose The Best Lighting Design for Football Stadium Field?

What Is Lighting Requirement of Football Field?

 

1. Lux Level (Brightness) Required for Football Stadium

The lux level standard is vastly different between televised and non-televised competitions. According to the FIFA’s stadium lighting guide, the class V (i.e. international televised such as World Cup) football field has the highest standard level of 2400 lux (vertical – the face of football players), and 3500 lux (horizontal – the turf). If the football field is for the community (recreational use), we need a 200 lux level. The high school or college football club can have 500 lux.

2. Uniformity Standard

Another important parameter is the lighting uniformity. It is a scale from 0 to 1 (max) reflecting the distribution of lumen across the sports field. It is the ratio of minimum illuminance to average illuminance (U1) or ratio of minimum to maximum (U2). Hence, if the lux level is quite similar, says around 650 to 700 lux, the difference between the minimum and the maximum value is very small, and the uniformity will be closer to 1. The lighting uniformity of the FIFA standard football stadium is 0.7, which is relatively challenging in the sports lighting industry.

3. Color Temperature

The general color temperature requirement of the football ground is larger than 4000K for all classes. Despite this suggestion, we usually adopt 5000K to 6000K cool white light to provide better illumination for the players and audience because these colors are more invigorating.

 

 

How TUBU makes a Professional Football Field Lighting Design For our client?

 

football-field-lighting-design-by-TUBU

Lighting design is sometimes referred to as photometric analysis. According to the football lighting design guidebook, the size of the football field, height, location, and number of light poles, illuminance level, and uniformity should be taken into account. Then, TUBU engineers will plan the luminaires in the following steps.

Step 1: Creating the Football Field

DIALux is a powerful yet free software for lighting designers because it can create almost all kinds of indoor and outdoor sports fields. There are different templates fields such as football field, tennis court, badminton court, and more. Afterward, the designer will draw the light pole with specific dimensions. The purpose is to simulate the real scenario and the placement of light. It helps give more accurate results.

Step 2: Planning the LED Flood Lights

The lighting engineer will then “affix” the luminaires onto the high-mast light poles inside the software. Different combinations of power, lumen output, and beam angle produce vastly different outcomes. Our job is to figure out the best design for football field lights. Since the requirement is different every time, we will design a unique, case-by-case solution.

Step 3: Generating the Photometric Analysis Report 

Lastly, we render the reports for our clients. It consists of several parts. The value chart contains the lux value across the field, which gives you the overall idea of how bright is the sports ground. The isolines joint the same illuminance into the same line, while the false-color rendering gives you a better visualization of the brightness of the field.

TUBU NSF LED Food Processing Lighting

NSF LED Food Processing Lighting

US Food and Beverage Factory LED Lighting Specifications, NSF Certification, and Product Design Recommendations LEDs are an important technology in the food and beverage manufacturing environment. Products and equipment must comply with complex regulatory regimes, including NSF certification.

In the United States, the food and beverage industry is heavily regulated by the US Food and Drug Administration (FDA) and the US Department of Agriculture (USDA). There are similar regulatory agencies in other parts of the world. In order to maintain hygienic conditions, all instruments and equipment (including lighting products) used in the production and packaging of food and beverages must comply with the strict manufacturing standards established by NSF International (NSF). In this article, we will briefly introduce NSF certification and explain whether industrial LED lighting is particularly suitable for these applications.

In fact, in order to maintain public health and worker safety, food and beverage facilities must meet some of the most stringent standards of the same industry. Originally established in the United States by the National Sanitation Foundation, NSF has operated NSF International worldwide since 1990.

Like many applications, food and beverage companies are increasingly adopting solid-state lighting (SSL) technology to achieve energy savings and longer LED life. However, today’s solid-state lighting (SSL) products provide a powerful environmental solution for all demanding regulatory requirements, making LEDs an ideal choice for NSF-certified lighting.

Food and beverage factory environment

The lighting equipment used in food and beverage plants is of the same type as in ordinary industrial environments, except that certain fixtures must be carried out under hygienic and sometimes dangerous conditions. The type of lighting product required and the applicable standards depend on the environment in a particular area; food processing facilities typically contain a variety of environments under one roof.

Factories may include multiple areas such as processing, storage, distribution, refrigerated or dry storage, clean rooms, offices, corridors, halls, restrooms, etc. Each area has its own set of lighting requirements. For example, lighting in food processing areas typically must withstand oil, smoke, dust, dirt, steam, water, sewage, and other contaminants in the air, as well as frequent flushing of high-pressure sprinklers and harsh cleaning solvents.

NSF has established criteria based on regional conditions and the extent of direct contact with food. The NSF standard for food and beverage lighting products, called NSF/ANSI Standard 2 (or NSF 2), divides the plant environment into three regional types: non-food areas, splash areas, and food areas.

NSF and food

Since the lighting products are not in direct contact with food, only the “Non-Food Zone and Splash Zone Guide” in NSF is applicable. LED lighting manufacturers seeking NSF-2 certification for their products must ensure that the shape design, materials used and manufacturing processes used are in compliance with the relevant NSF standards.

In some locations, such as grain processing plants, areas with combustible dust or flammable gases can create dangerous conditions. In these environments, food and beverage lighting products are typically classified as “hazardous applications” in the US National Electrical Code.

Ceilings in various areas of food processing plants can also pose challenges for industrial LED lighting. In addition to frequent flushing, these ceilings sometimes have to support the weight of pipes and other equipment as well as maintenance personnel, which complicates the installation and replacement of lighting equipment. In addition, the ceiling of the refrigerating compartment and the venting chiller room should be as thick as the thermal barrier but may affect the structural integrity of the ceiling installation. Lower ceilings also require a luminaire with a wider beam angle for vertical horizontal illumination.

Lighting specifications for food processing

Like most lighting applications, IESNA (North American Lighting Engineering Association) has set recommended lighting levels for a variety of food processing activities. For example, IESNA recommends that the food inspection area has an illumination range of 30 to 1000 fc, a color classification area of 150 fc, and a warehouse, transport, packaging, and restroom of 30 fc.

However, since food safety also depends on good lighting, the US Department of Agriculture requires adequate lighting levels in Section 416.2(c) of its Food Safety and Inspection Service Manual. Table 2 lists the USDA illumination requirements for selected food processing areas.

Good color reproduction is critical for accurate inspection and color grading of foods, especially meat. The US Department of Agriculture requires a CRI of 70 for general food processing areas, but a CRI of 85 for food inspection areas.

In addition, both the FDA and the USDA have developed photometric specifications for vertical illumination distribution. Vertical surface illumination should measure 25% to 50% of horizontal lighting and there should be no shadows where it is possible to compromise critical plant areas.

TUBU Food Processing Lighting futures:

  • In view of the many hygienic, safety, environmental, and luminosity requirements of the food industry for lighting equipment, industrial LED lighting manufacturers should meet the following key design elements:
  • Use non-toxic, corrosion-resistant, and flame-retardant lightweight materials such as polycarbonate plastic and certain metals
  • Avoid using glass if possible
  • Design a smooth, dehydrated outer surface with no gaps, holes, or grooves that may retain bacteria
  • Avoid paint or coating surfaces that may peel off
  • Use tough lens material to withstand multiple cleanings, no yellowing, and wide and even illumination
  • Uses efficient, long-lasting LEDs and electronics to operate well in high temperatures and refrigeration
  • Sealed with NSF-compliant IP65 or IP66 lighting fixtures, still waterproof and prevent internal condensation under high pressure flushing up to 1500 psi (splash zone)
  • Since food and beverage plants can use many of the same types of lighting, standing industrial LED lighting products may also be an alternative to NSF certification, including:
  • Equipment with IP65 (IEC60598) or IP66 (IEC60529) protection rating
  • Luminaires with UL wet or UL moisture rating
  • Airtight products in hazardous locations (eg Class I, Class 2, Groups A, B, C, and D)
  • Cleanroom equipment (eg ISO-14644, Category 3 to 9, Federal Standard 209E, Category 1)

LED food and beverage lighting advantages

For the food and beverage industry, properly designed LEDs have many advantages over most traditional lighting, such as the absence of glass or other fragile materials that may contaminate food, improving light output, and low-temperature conditions in cold storage. Efficiency, low maintenance costs, longer life (70,000 hours), non-toxic mercury, higher efficiency, wide adjustability and control, instant performance, and wide operating temperature.

The emergence of efficient solid-state lighting (SSL) makes it possible to apply smooth, lightweight, sealed, bright, high-quality lighting for many food industry applications. Long LED life and low maintenance can help transform the food and beverage industry into a clean, green industry.

What is a LED batten light fitting?

What is a LED batten light fitting?

Batten light fittings come in all shapes and sizes and are used in a variety of different settings, depending on requirements.

Batten fittings typically house one or two tube lights and are commonly used in public areas such as car parks, toilets, and train stations. These versatile units are popular because of their durability, long lifespan, and ease of maintenance, as well as providing a good light output.

Public places such as car parks often require robust, enclosed lighting units as they can not only be subject to wear and tear from elements like weather and vandalism, but also provide safety. As a result, batten fittings are perfect for these types of installs.

Traditional fluorescent tube lights generate heat and are hot to touch – anyone who has tried to change a traditional halogen light bulb at home once it has been on for a while is a testament to this, and as you can imagine exposure is not ideal.

Furthermore, fluorescent tube lights are often made from glass, which again, is hazardous to have in public places for the exposure of broken glass when damaged.

 

New LED technology

The newest technology in LED batten lights features no tubes at all. Batten fittings such as TUBU’s L10-K Series use surface mounted diode (SMD) chips on an aluminum board. This way of generating light is a more effective way for battens for a number of reasons:

  1. Less heat emitted
  2. 90% of the energy produced by LEDs is converted to light ensuring minimal energy is wasted generating heat. This means they are 90% efficient making them much more energy-efficient than halogen or fluorescent lights.
  3. A directional and focused beam of light
  4. The SMD’s are mounted to the underside of the light, thus emitting light in one direction. This ensures maximum light is outputted with minimal power consumption. Tube lights emit light 360º wasting light.
  5. No flicker / Instant on
  6. LEDs are instant on and do not flicker. Fluorescent lights are notoriously known to flicker and take a while to reach full power. Motion sensors and other lighting controls are hardly ever used with fluorescent lights because of this.
  7. Energy saving
  8. Because of the high efficiency of LED output as well as control on the beam angle, the use of light is better distributed. On average, using LED over fluorescent, you can get the same light output with just 50% of the energy consumption.

 

Tri-Proof and non-corrosive

Batten fittings used in public places must be tri-proof or non-corrosive. This means they are more durable and robust than normal tube housing. Tri-proof units can withstand heavy impact, exposure to dust and water, and exposure to extreme temperatures.

  • An IK chart measures impact. Tri-proof units have a rating of IK08 or IK10.
  • An ingress protection (IP) rating measures water and dust exposure. Tri-proof units are typically is IP65 or higher.
  • Tri-proof rated products can withstand temperatures from -20ºC to 40ºC.

In addition, tri-proof fittings are built to last by using non-corrosive, high-grade plastic, and stainless steel.

 Ease of Installation 

Another reason for batten fittings’ popularity is the ease of installation. Fitted by chain or bracket or fixed to a surface, often a few screws are all that is needed.

The lights themselves can be linked to each other with ease or connected to a power supply like a house light.

LED tri-proofs, come with a long lifespan, typically anywhere between 20,000 and 50,000 hours, meaning they can last years without any need for maintenance or replacements.
