LED plant lighting is beneficial to greenhouses, but standards need to be improved

A recent study published by Rutgers University in the United States pointed out that although LED lighting can enhance the growth of greenhouse plants, standards still need to be established to determine the best light intensity and color to improve the energy efficiency of horticultural lighting products.

LED plant lighting is beneficial to greenhouses, but standards need to be improved

At present, many lighting companies are selling LED products. The “light formula” usually consists of a combination of wavelength and color ratio, such as a 4:1 red-blue ratio of the spectrum. Plant scientists often use this information to assess the potential effects of lights on plant growth and development. But according to a study to be published in Acta Horticulturae, there is still a lack of standardized procedures for how to calculate these ratios.

AJ Both, a professor in the Department of Environmental Science at Rutgers University and an expert in controlled environmental engineering, said: “The more efficient the auxiliary light source, the less electricity the grower needs to plant crops. We hope to increase indoor crops in a more sustainable and cost-effective way. Production.”

Improving energy efficiency will have a major impact on growers, and information about new plant lighting strategies will help the booming indoor agricultural industry.

According to Both’s previous research, in greenhouses and controlled environments, lamps are used to supplement sunlight and extend the lighting time, helping to produce horticultural crops such as vegetables, flowers, and herbs. The latest developments in energy-saving LED technology to provide a variety of lighting options for the horticulture industry. However, due to the lack of independent information on the performance of the lights, growers cannot easily compare the various lighting technologies and LED options. The study proposes to standardize product labels, which can compare lamps between manufacturers.

Both and colleagues will continue to work on independently evaluating performance indicators, such as power consumption, efficiency, light intensity, and light distribution patterns, and pass this information to commercial growers. His research shows that the latest developments provide opportunities to precisely control the light of LED lights and study the effects on plant growth and development.

This new study recommends the use of a spectroradiometer to measure light output in a specific wavelength range. Researchers report that comparing sunlight with ordinary lamps (including LEDs, high-pressure sodium lamps, incandescent lamps, and fluorescent lamps for plant lighting), the ratio of light is very different. The researchers hope that the work will help develop a standard definition for a specific band (wavelength range).

Over 300 domestic plant lighting industry chain manufacturers

Driven by multiple factors such as the legal commercialization of special cash crops in North America, the epidemic has promoted global awareness of food crises, land shortages, and the rise of plant factories, plant lighting has developed rapidly in recent years. According to the statistics of Frost & Sullivan, the global plant supplement light equipment market has increased from USD 1.76 billion in 2015 to USD 3.79 billion in 2019, with an average annual compound growth rate of 21.1%. Frost & Sullivan predicts that from 2020 to 2024, the compound annual growth rate of the global plant lighting equipment industry market size will remain at 25.5%, and the market size will reach 11.50 billion U.S. dollars in 2024.

Over 300 domestic plant lighting industry chain manufacturers

There are currently four main types of plant lighting on the market: LED lamps, fluorescent lamps, high-pressure sodium lamps, incandescent lamps, and halogen lamps. According to OFweek Industrial Research Institute, by 2021, the global LED plant growth lamp market will account for 60%. It is expected that the penetration rate of LED light sources will further increase in the future, occupying the mainstream of the plant lighting field.

The current global LED plant lighting downstream application market is still mainly concentrated in Japan, the United States, the Netherlands, and other countries. According to the statistics of the LED Research Institute of Gaogong Industry Research, my country’s LED plant lighting exports in 2020 will exceed 500 million US dollars, an increase of 426.3% over the same period last year. According to data from Zhiyan Consulting, the output distribution of my country’s LED plant lighting systems and lamps market in 2019 is 108,300 sets and 409,900 sets, domestic demand is only 14,957 sets, and 59,846 sets, and overseas market demand accounts for seven-eighths.

my country’s LED plant lighting stock market is relatively small, and there is huge room for growth in the future. Compared with the same period in 2018, the market demand for LED plant lighting systems and lamps in my country has grown rapidly in 19 years, with year-on-year growth rates of 21.94% and 22.46% respectively. The Chinese Academy of Agricultural Sciences predicts that according to the current scale of my country’s agricultural industry, the demand for agricultural LED lighting fixtures and their control equipment will reach several billion yuan in the next five years.

On the one hand, in the past ten years, the recreational marijuana industry has gradually begun to legalize. Most countries prohibit the use of cannabis for recreational purposes. In addition to prohibiting the cultivation, sale, and smoking of cannabis, the law also imposes heavy taxes on businesses and individuals that legally grow and sell cannabis. But the Netherlands has always implemented an informal decriminalization policy on cannabis. In 13 years, Uruguay became the first country in the world to legalize the sale and cultivation of cannabis; on October 18, Canada followed closely. Currently, recreational marijuana is legalized in countries such as Canada, Georgia, and Uruguay, as well as some states in the United States. The vast majority of hemp needs to be grown indoors, and these increased demands will drive the growth of plant factories, thereby driving the demand for the plant lighting market.

On the other hand, all countries and regions around the world are promoting vertical farms. Vertical farms with huge growth space in the future will continue to drive the growth of the plant lighting market. According to statistics from Frost & Sullivan, it is estimated that in 2024, the global market size of plant supplementary lighting equipment applied to the plant factory sector will reach 1.47 billion U.S. dollars, and the compound annual growth rate from 20 to 24 will reach 44.2%.

Because of the low cost of traditional plant lights, they are still used in plant lighting. However, as artificial light source technology matures, LED light sources with more advantages gradually replace traditional light sources and gradually become the main light source for plant lighting. LED light source plant lighting is more efficient and energy-saving. The use density of lamps for agricultural lighting is extremely high compared to general lighting. San’an Zhongke’s research shows that plants with high light demand consume up to 500-1000W of electric power per square meter of planting area, which places stringent requirements on the electrical-to-optical conversion efficiency of plant lights. At present, the electro-optical conversion efficiency of LED plant lamps is more than 20 times that of incandescent lamps, 3 times that of fluorescent lamps, and nearly twice that of high-pressure sodium lamps.

In terms of driving power, LED plant lighting driving power has more stringent requirements than other LED driving power in terms of conversion efficiency, temperature control, precise dimming, and warranty life. In terms of conversion efficiency, the higher the efficiency of the LED plant lighting drive power supply, the lower the power loss and the loss efficiency in the form of heat dissipation. For terminal planting, it can not only save electricity expenses but also control the temperature in the plant factory, so that excessive temperature will not affect the optimal growth of plants. In terms of precise dimming, the LED plant lighting drive power supply provides functions such as adjustable spectrum and intelligent programming to realize that the plant lighting system finally outputs the light required by the planted plants according to the spectral requirements of different plants. In terms of warranty life, plant lighting needs a longer warranty life of the power supply, so there are higher requirements for the reliability and quality of the driving power supply.

Domestic companies are rapidly deploying plant lighting business. In 2020, there will be more than 300 companies engaged in plant lighting in my country. Upstream chip manufacturers such as San’an Optoelectronics, HC Semitek, and Qianzhao Optoelectronics have deployed the plant lighting LED light source market segment, and midstream packaging companies such as National Star Optoelectronics, Hongli Zhihui, Everlight Electronics, and other leading companies have focused on plants. Lighting technology.

TrendForce forecasts that the global LED lighting market will reach 38.199 billion US dollars in 2021, with an annual growth rate of 9.5%.

2021-2022 Global LED Lighting Market Outlook

The main growth momentum of the general lighting market comes from four factors:

1. With the gradual popularization of vaccines in various countries, the market economy has gradually recovered, especially the rapid recovery of commercial, outdoor, and engineering lighting.

Second, the price of LED lighting products increased: With the pressure of rising raw material costs, lighting brand manufacturers continued to increase product prices by 3-15%.

3. With the support of energy-saving and emission-reduction policies in various countries around the world, in order to achieve the goal of “carbon neutrality”, LED energy-saving renovation projects have been gradually launched, and the penetration rate of LED lighting has continued to increase. According to TrendForce’s analysis, the LED lighting market penetration rate will increase to 57% in 2021.

4. Under the epidemic situation, LED lighting manufacturers are accelerating their deployment towards digital intelligent dimming and regulation of lamps. The future lighting industry will also pay more attention to the systemization of connected lighting products and the added value brought by human health lighting.

Qingdao Metro basically achieves full coverage of LED lighting

After the country made the major strategic decision of “carbon peak by 2030 and carbon neutral by 2060”, relevant departments have successively issued guidelines on accelerating the development of new energy storage, and a series of notices on further improving the time-of-use electricity price mechanism. The policy document promotes the implementation of the “dual carbon” goal in the power sector, and the transportation sector requires “accelerating the promotion of green and low-carbon development, and the carbon dioxide emissions in the transportation sector reach the peak as soon as possible.” For many years, Qingdao Metro has been committed to exploring how to better fulfill its social responsibility for green development, and play an exemplary and leading role in green and low-carbon development.

Qingdao Metro basically achieves full coverage of LED lighting

Taking the development history of lighting lamps as an example, from high-energy-consuming incandescent lamps to low-power LED lamps, behind the realization of energy saving is strong support for technological innovation. Qingdao Metro has always placed technological innovation in a prominent position, actively carried out energy-saving “four new” technology application research in the whole process of design, construction, and operation, and continuously promoted equipment energy-saving upgrades, and strived to reduce operating energy consumption from the source. Through technological innovation, Qingdao Metro has saved more than 10 million kilowatt-hours of electricity per year and reduced carbon dioxide emissions by 10,000 tons.

Develop clean energy and obtain clean energy from nature. Qingdao Metro has vacant roofs and elevated station roofs in some sections of the site, and installed photovoltaic power generation with an installed capacity of 3MWp and an annual power generation of 3 million kWh; photovoltaic street lights are used in the Anshun depot to achieve “zero” power consumption for road lighting; parking in Lingshanwei uses air-source heat pumps to absorb heat in the air to provide heat for the office area. In addition, Qingdao Metro has completed the photovoltaic design of the idle roofs of 4 depots, with a construction area of 181,000 square meters and a total installed capacity of 16MWp. It is expected to generate 18 million kWh of electricity annually. The development of clean energy is an effective way to achieve sustainable development. In the future, Qingdao Metro will continue to cultivate in the field of clean energy represented by solar energy, wind energy, and hydrogen energy, paving the way for the application of clean energy in the rail transit industry.

Pay attention to the utilization of waste energy and turn waste electricity, waste heat, and wastewater into treasure. Metro trains generate electricity when braking, but the generated electricity is too much to be fully utilized, and a large part of it will be wasted in the form of heat energy. Qingdao Metro has installed nearly 40 regenerative braking energy absorption devices to collect the wasted electricity for supply. Vehicles and station equipment are reused, saving more than 9 million kilowatt-hours of electricity annually. The operation of subway equipment will generate a lot of heat, which requires ventilation and air-conditioning for cooling. Qingdao Metro adopts heat pump heat recovery technology on Line 13 to collect waste heat and provide heat for the public areas of the station and office buildings, which not only saves cooling energy consumption but also reduces heating energy consumption. A sewage treatment system is set up at the site to treat production and domestic wastewater to form reclaimed water for sanitary cleaning and green irrigation, so as to realize the recycling of water resources. Waste energy utilization is an effective means to reduce energy waste. In the future, Qingdao Metro will conduct applied research in the field of composite energy storage represented by flywheel energy storage to promote the rapid iterative upgrade of energy storage equipment in the rail transit industry.

Improve the energy efficiency level to make the equipment more efficient and lower energy consumption. The 112 stations on the Qingdao Metro line network basically achieve full coverage of LED lighting. The early stage of the site has also completed the energy-saving transformation of 4450 metal halide lamps. Only the lighting of the site section is retrofitted, which can save up to 1.1 million kilowatt-hours of electricity; the line network use frequency conversion escalators and no one automatically turns to idle speed operation, reducing no-load energy consumption; 36 sets of integral, direct expansion evaporative and condensing cold water systems are used for lines 1, 2, and 13, and some of them use magnetic levitation coolers to replace the traditional screw chiller not only improves the heat exchange efficiency and saves operating energy consumption, but also saves the area of the cooling tower and avoids the problem of noise disturbance. The use of high-energy-efficiency equipment can significantly improve energy efficiency. In the future, Qingdao Metro will conduct technical research in the field of traction energy-saving represented by permanent magnet technology to help train energy efficiency in the rail transit industry.

How to reduce light pollution caused by outdoor LED lighting?

During the New Year holidays, houses and businesses are decorated with holiday lights, many of which are equipped with LEDs. These decorations are usually only lit for a period of time on holiday nights, but those permanent lighting fixtures that are always on throughout the year are different.

How to reduce light pollution caused by outdoor LED lighting?

Anyone who has flown over cities at night knows that all these lights are fascinating, but unfortunately, they make the sky glow and can have serious adverse effects, especially on wildlife and vegetation.

As the lighting industry gradually reduces the use of traditional light sources (such as high-pressure sodium or metal halides for outdoor lighting), people are paying more and more attention to how to minimize the light pollution caused by outdoor LED devices.

GFZ German Earth Science Research Center recently released the results of a study on urban street lighting in Tucson, Arizona, in-depth analysis of how well-designed LED lamps can minimize light pollution. Tucson is the city that uses LED lighting the most. Almost all street lights have been upgraded and have wireless communication and dimming functions. The study was conducted for 10 days in March and April 2019, and images of the Tucson area were acquired at night through the Suomi National Polar Orbiting Partnership (NPP) satellite of the United States. At some nights, about 14,000 of the total 19,500 street lights are set to full brightness, other times they are set to 30% bright.

The research team concluded that about 20% of the nighttime light in Tucson is from street lights, and the rest is generated by architectural signs and curtain walls, shop windows, sports fields, etc. If these conclusions apply to other cities, it indicates that LED lighting design may be able to solve the problem of light pollution.

In order to minimize light pollution or stray light, the most important tool used by luminaire designers is the “BUG” rating system. “BUG” stands for backlight, upward light and glare. The BUG rating system is jointly developed by the Lighting Engineering Association (IES) and the International Dark Sky Association (IDA), which can provide a unified method to evaluate the amount of stray light generated by outdoor lighting.

Stray light in the outdoor environment is harmful and unhelpful. It not only causes the sky to glow, but also causes unnecessary energy consumption. Examples of stray light are intrusive light (that is, light that enters from an undesired position, such as light from a street lamp into a nearby window), upward light that helps the sky glow, and glare (light that is flush with the line of sight). Too much light can cause discomfort or visual impairment).

According to the lumen output measured in each of the three areas shown in Figure 2, the BUG rating can be obtained.

As the name suggests, backlight refers to the light emitted behind the lighting equipment. The backlight area can be further divided into four sub-areas, and the corresponding emission angles range from 0 degrees (that is, the light points downward to the ground) to 90 degrees (most of the light is parallel to the ground and points to the outside). Similarly, the glare area is also divided into four sub-areas, and the emission angle increases from low glare to high glare. The upward illumination area includes only two sub-areas, one area contains light mainly directed upwards, and the other area contains light mainly directed outside.

The look-up table of IES TM-15-11 (Outdoor Lighting Classification System) quotes the measured lumens of each of the above-mentioned partitions, and the value assigned to each parameter is in the range of 0~5, and the BUG rating is based on this. For example, the BUG level B0 U0 G0 is assigned to the lighting device that emits downward light; the BUG level of B2 U0 G2 is assigned to the lighting device that emits most of the illuminating light forward and backward, but not upward. Please note that the BUG level is only a factor in determining whether a lighting device is suitable for a particular lighting application. Generally, the lower the BUG level, the lower the possibility of light pollution.

LED plant growth lights light up the dragon fruit field

At the moment when tropical fruits are harvested in summer, Dazhai Village, Xindian Town, Xiang’an District, Xiamen is the largest pitaya plantation base in Fujian. More than 1,400 acres of pitaya ushered in a bumper harvest, and the use of black technology allows one acre of land to be able to Too much fruit, good fruit.

LED plant growth lights light up the dragon fruit field

As night fell, 20,000 LED lights in the farmland of Xiamen Dazhai Village were lit up at the same time, illuminating more than 1,400 acres of dragon fruit fields. The dotted dragon fruit fields attracted many tourists. However, illuminating the dragon fruit field is not to attract tourists. It is a black technology used by local fruit farmers to increase production and income.

According to reports, the fruit-producing period of pitaya can last from June to the Spring Festival of the following year after supplementing the light at night and increasing the income per mu by about 3,000 yuan. At five o’clock every day, fruit growers start picking dragon fruit in the field, and many buyers squat directly at the door of the cooperative. The fresh fruits have been ordered before they are packed and sorted. According to statistics, more than 100,000 catties of dragon fruit are sold from Dazhai Village to all parts of the country every day.

Understand that LED plant lights can be made with UVA lamp beads, LED plant lights can affect the growth cycle of plants, and LEDs of specific wavelengths can affect the flowering time, quality, and duration of the plant. LEDs of certain wavelengths can increase the number of flower buds and flowering of plants; LEDs of certain wavelengths can reduce the flower formation response, regulate the length of the stalk and the flowering period, which is conducive to the production and marketing of cut flowers. It can be seen that the flowering and subsequent growth of plants can be regulated by LED regulation.

The era of construction machinery LED lighting is coming

Under the two-wheel-drive of the country’s energy transformation and upgrading and environmental protection, accelerating the energy-saving and emission reduction of construction machinery has become the target task of the industry. An excavator is equipped with at least 4 high-power lighting fixtures for night and tunnel construction, and the energy consumption of lighting cannot be ignored.

The era of construction machinery LED lighting is coming

The essence of LED lamps is a solid-state semiconductor that can convert electrical energy into visible light. Its biggest advantage lies in its extremely low energy consumption. Today, when energy saving and emission reduction are advocated, it has become an energy-saving and consumption-reducing work device for construction machinery products except for power and other working devices. Important applications outside. At the same time, the service life of LED lamps is even more of an advantage, up to more than 50,000 hours. Moreover, its high brightness, strong penetrability, instant start speed, and low-voltage safety attributes can greatly improve product quality, improve work efficiency, reduce light pollution, save energy and reduce emissions, and reduce workplace injuries. These advantages make LED lamps more and more The preferred choice for multiple engineering machinery products.
