LED lighting can be widely used in the plant tissue culture, the production of leafy vegetables, greenhouse fill light, plant plants, plant breeding, cultivation of medicinal plants, edible plants, algae culture, plant protection, space fruits and vegetables, flowers planted, drive to kill mosquitoes and other field, planting out of fruits and vegetables, flowers, herbs and other plants to meet military border posts, alpine regions, lack of water and electricity resources required area, home office gardening, marine space personnel, and other regions or specific patient populations.
Currently on the market has developed and produced a number of LED plant lighting devices, such as LED grow lights, plant growth chambers, house plant grow lamp with LED, drive to kill mosquito lights. Wherein the LED Grow Light common morphology bulbs, lights, panel lights, lights, downlights, light grid and so on.
The following are entering the LED plants lighting industry should know six basic points.
First, LED plant lighting market demand so much, if you want to enter the greatest difficulty in what?
LED lighting plant is a product of biology, facility horticulture, vegetable, plant physiology, plant nutrition, bio-environmental engineering, LED lighting, intelligent control technology, interdisciplinary and organic development. So only good at semiconductor plants, one or both of the intelligent system are fully cross-collaboration is critical enough and research applications. The most difficult plants to enter the LED lighting market is to develop the production yield and quality of plant ecology LED light source or luminaire, we need to solve the intelligent control of light environment, plant photobiology, LED semiconductor technology issues and how to integrate the three integral development.
Second, the plant photobiology What does it mean?
Plant photobiology law is an important basis for LED lighting plant, including the number of properties under light conditions (light intensity and photoperiod), mass properties (light quality and spectral), electric light emission characteristics (duty cycle, frequency) and so on. Plant photobiology with high complexity and systemic. Light quality refers to the biological role of the type of light quality, including visible light, UV and far-red light. Light quality biology, we need to figure out the following issues: first, light quality biological function, a single light quality and research complex light quality on plant growth, yield and quality and impact of physiological metabolism, molecular biology and proteomics Mechanism ; second, between plant species and varieties of light quality and adaptability to exploit differences in the mechanism; third, light quality interactions with other environmental factors of biological mechanisms; fourth, the number of properties of light quality lighting facilities effective threshold and the reference value. In addition, a clear low-light stress biology light quality, light and response mechanism photosynthetic apparatus under continuous light operating efficiency also needed.
Third, why light recipe different companies the same plant will be different?
The establishment of various plant growth and development, quality and high yield the desired formulation development based LED lighting plant lighting industry. Light recipe is a high yield and quality as the goal, according to the characteristics of plant species and varieties of light quality growth parameter types and number of attributes required for each stage set. Each plant and different growth stages optimum lighting recipe is different. Why different companies for the same plant light formula will be different, even a big difference? The main goal of plant growth and business have a certain relationship. Simply put, companies according to market demand and their own development needs, can reduce the requirements and only need more than the growth of plants minimum light formula needs other environment on biological growth also relaxed the requirements of the case, not only the light recipes are not the same, for environmental control system will be very different. Instead, companies can also be critical, as far as possible to create the best environment for the growth of plants and conditions, such as research and development of light like a recipe. Future have been put forward with LED lighting plant China’s relevant standards and requirements, light recipe speak progressive unification or consistent basic conditions.
Fourth, LED plant growth light source and lighting research and development production requires attention to what principles?
LED Grow light lamps lighting plant is the core LED industry, companies need to develop formulations according to the light required for plant growth light lamps. Pay attention to the following four principles: First, high energy efficiency principles, formulate a reasonable degree of spectral components increase the maximum luminous efficiency LED light source, the light source and reduce the distance between the irradiated plants, reducing light loss and improve energy efficiency; second , low-cost principle, the cost is one of the most important factors that determine plant LED lighting industrial development; third, the principle of ecological security, in red and blue spectrum, a slight increase or a small amount of a green component to increase the visual health; the fourth priority the development of high value-added plant dedicated LED light lamps.
Fifth, what plants light control is the environment, including what?
Light environment control based on quality and high yield as the goal, the production plant factory system cultivated plant species and varieties grown each stage light formula is based on direct control of environmental parameters and switching of light through the computer’s time and space management. For example, greenhouse fill light to consider natural light diurnal variation of parameters, environmental parameters, plant photosynthetic parameters, plant growth stage and lighting properties, to implement cost-effective fill light approaches to meet the light intensity, light quality, photoperiod demand, energy efficient. Plant light environment control mainly refers to control LED lamps light quality, light intensity, photoperiod, spatial location and rate of movement and so on. Light environment control has obvious spatial and temporal characteristics, thus establishing a dynamic real-time control is very important to realize LED lighting light plant environmental control automation and intelligence is the trend.
Sixth, LED grow lighting design focuses on which indicators and performance?
LED plant lighting designers need to focus on the following indicators and performance: 1, illumination uniformity; 2, light quality group with rationality; 3, heat reliability; 4, LED power chip suitability; 5, light-emitting surface the efficiency; 6, visual comfort.
