6 basic points you should know when entering the LED plant lighting industry.
1. The LED plant lighting market demand is so great, what is the biggest difficulty if you want to enter?
LED plant lighting is the product of multidisciplinary and organic integration development such as biology, facility horticulture, vegetable science, plant physiology, plant nutrition, biological environmental engineering, LED lighting, and intelligent control technology. Therefore, it is not enough to be good at one or both of semiconductors, plants, and intelligent systems. Full collaboration and cross-research applications are essential.
The biggest difficulty in entering the LED plant lighting market is to develop and produce high-yield, high-quality and ecological LED plant light sources or lamps. It is necessary to simultaneously solve the development problems of how to integrate and integrate the intelligent control of light environment, plant photobiology, and LED semiconductor technology.
2. What is plant photobiology?
The study of the law of plant photobiology is an important basis for LED plant lighting, including the study of the quantitative attributes (light intensity and photoperiod), quality attributes (light quality and spectrum) of the light environment, and the luminous characteristics of electric light sources (duty cycle, frequency), etc. Plant photobiology is highly complex and systematic.
Light quality refers to the type of light quality that has an effect on living things, including visible light, UV and far-red light. In terms of light quality biology, we need to clarify the following issues: First, the biological functions of light quality, the physiological metabolism, molecular biology and proteomics mechanism of the effects of single light quality and compound light quality on plant growth, yield and quality ；
Second, the mechanism of light quality adaptability and utilization differences among plant species and varieties; third, the biological mechanism of interaction between light quality and other environmental factors; fourth, the effective threshold and benchmark value of light quality attributes of lighting facilities. In addition, the response mechanism of the photosynthetic mechanism's operating efficiency under low light, strong light and continuous light needs to be studied.
3. Why do different companies have different lighting formulas for the same plant?
Establish the basis for the development of the LED plant lighting industry with the lighting formula required for the growth and development of various plants, high-quality and high-yield. The illumination formula is based on the goal of high quality and high yield, according to the characteristics of plant species and the set of parameters of light quality and quantity attributes required at each stage of the growth and development of the species. The suitable lighting formula for each plant and different growth stage is different.
Why are the lighting formulas of different companies for the same plant different, or even very different? This is mainly related to the company's goal of plant growth. To put it simply, companies can reduce the requirements according to market demand and their own development needs. They only need to exceed the minimum light formula requirements for plant growth. If they also relax the requirements for other environments for biological growth, not only the light formula will be different, but also the environmental control. The system will also be very different.
On the contrary, companies can also make strict requirements and try to create the best growth environment and conditions for plants, so that the light formula developed is good. In the future, with the introduction of relevant standards and requirements in the field of LED plant lighting in my country, the lighting formula will gradually be unified or maintain the consistency of basic conditions.
4. What principles should be paid attention to in the development and production of LED plant growth light sources and lamps?
LED plant growth light sources and lamps are the core of the LED plant lighting industry. Enterprises need to develop the light sources and lamps needed for plant growth according to the lighting formula. Pay attention to the following four principles: First, the principle of high light energy utilization, formulating reasonable spectral components to maximize the luminous efficiency of the LED light source, reducing the distance between the light source and the illuminated plant, reducing light loss, and improving light energy utilization efficiency;
Second, the principle of low cost, cost is one of the most important factors that determine the industrial development of LED plant lighting; third, the principle of ecological safety, in the red and blue spectrum, adding a trace or a small amount of green light components to increase visual health; fourth , Prioritize the development of LED light sources and lamps for plants with high added value.
5. What is the control of plant light environment and what aspects are included?
The light environment control is aimed at high quality and high yield, based on the plant species cultivated in each production system of the plant factory and the lighting formula at each stage of the species growth, and the spatiotemporal management of the light environment parameters is directly controlled and switched by the computer.
For example, greenhouse light supplementation needs to consider diurnal changes in natural light parameters, environmental parameters, plant photosynthetic physiological parameters, plant growth stages and lamp properties, and implement cost-effective light supplementation methods to meet the needs of light intensity, light quality, and photoperiod, and save energy and efficiency.
Plant light environment control mainly refers to the control of the light quality, light intensity, photoperiod, spatial position and movement rate of LED lamps. Light environment control has obvious temporal and spatial characteristics, so it is very important to establish dynamic real-time control. It is the general trend to realize the automation and intelligence of LED plant lighting light environment control.
6. What indicators and performance are the main focus of LED plant lighting design?
Designers of LED plant lighting fixtures need to pay attention to the following indicators and performance: 1. The uniformity of illumination; 2. The rationality of light quality configuration; 3. The reliability of heat dissipation; 4. The suitability of LED chip power; 5. Light emitting surface High efficiency; 6, visual comfort.
