Into the LED plant lighting industry should know the six basic points

May 17, 2017

1. Where is the biggest difficulty?

LED plant lighting is a product of biology, facilities, horticulture, vegetable science, plant physiology, plant nutrition, biological environment engineering, LED lighting, intelligent control technology and other interdisciplinary and organic combination of the product. So it is not enough to be good enough for one or both of semiconductors, plants, intelligent systems, and full collaboration and cross research applications are essential. Into the LED plant lighting market is the biggest difficulty in the development and production of high yield and high quality ecological LED plant light source or lamp, you need to address the light environment, intelligent control, plant photobiology, LED semiconductor technology, how the integration of the three and one of the development issues.

2. What is plant photobiology?

Study on plant photobiological laws is an important basis for LED plant lighting, including the study of the number of light environment properties (light intensity and photoperiod), quality attributes (light and spectrum), light source luminous characteristics (duty cycle, frequency) and so on. Plant photobiology is highly complex and systematic.


Light quality refers to the type of light quality that affects the organism, including visible light, UV and far red light. Light quality biology, we have to figure out the following questions:

First, the biological function of light quality, the physiological metabolism, molecular biology and proteomics mechanism of single light quality and composite light quality on plant growth and yield quality were studied.

Second, the plant species and varieties of light quality adaptability and the use of differences between the mechanism;

Third, the biological mechanism of interaction between light and other factors of the environment;

Fourth, the lighting quality of the light quality of the property of the effective threshold and the reference value.

In addition, the response mechanism of photosynthetic efficiency of photosynthetic apparatus under the light, light and continuous light of adversary light quality biology also needs to be studied.

3. What is the difference in the light of different companies but with the same plant?

The establishment of a variety of plant growth and development, high quality and high yield of the necessary lighting formulations is the basis for the development of LED plant lighting industry.

Light formula is a high quality and high yield as the goal, according to the characteristics of plant species and species growth and development stages of the required light quality species and the number of attributes of the set of parameters. Each plant and the different growth stages of the appropriate light formulations are different.

Different enterprises for the same plant light formula will be different, or even a big difference, mainly on the plant and plant growth goals have a certain relationship. Simply put, the enterprise according to the needs of the market and their own development needs, can reduce the demand, only need to plant more than the minimum light growth requirements of the plant, the biological growth of other environments also relaxed requirements, not only the lighting formula will be different for environmental control The system will be very different.

On the contrary, companies can also be strict requirements, as far as possible to create the best plant growth environment and conditions, so the development of the light like the formula. The future with China's LED plant lighting related standards and requirements of the introduction, the lighting formula to gradually harmonize or maintain the consistency of the basic conditions.

4. LED plant growth light and lighting R & D production need to pay attention to what principles?

LED plant growth light source and lamp is the core of LED plant lighting industry, enterprises need to light according to the formula to develop plant growth required light and lamps.

The following four principles should be noted:

First, the principle of high light energy utilization, the development of reasonable spectral components to maximize the luminous efficiency of LED light source to reduce the distance between the light source and the irradiated plants, reduce light loss, improve light energy efficiency;

      Second, the principle of low cost, cost is to determine the industrialization of LED lighting industry, one of the most important factors;

Third, the principle of ecological security, in the red and blue spectrum, increase the amount of trace or a small amount of green light components, increase visual health;

Fourth, give priority to the development of high value-added plant-specific LED light source and lamps.

5. What is the plant light environment control, including what?

Light environment control is based on high quality and high yield as the goal, the plant plant production system of cultivated species and varieties of various stages of light growth formula based on the computer through direct control and switching light environment parameters of time and space management.

For example, the greenhouse light needs to consider the daily variation of natural light parameters, environmental parameters, plant photosynthetic physiological parameters, plant growth stage and lamp properties, the implementation of cost-effective method to meet the light intensity, light quality, photoperiod demand, energy efficient.

Plant light environment control is mainly to control the LED light quality, light intensity, photoperiod, space position and movement rate. Light environment control has obvious temporal and spatial characteristics, so the establishment of dynamic real-time control is very important to achieve LED plant lighting environment control automation, intelligent is the trend.

6. LED plant lighting design is mainly concerned about what indicators and performance?

LED plant lighting fixture designers need to focus on the following indicators and performance: 1. The uniformity of light; 2. The rationality of light distribution; 3. Thermal reliability; 4.LED chip power suitability; 5. The efficiency of the visual comfort.
