Application and development of LED Grow Light
At present, the application LED plant lighting is relatively wide, which can be simply divided into the following application occasions:
1, Home growing;
LED growth lamps are characterized by low power, high luminous efficiency and low calorific value, so they have been widely used in home lighting. In the field of household plant lighting, led naturally becomes the first choice, which can be applied to household plant desk lamp, household plant planting rack, household vegetable growth machine and so on. With the improvement of people’s living standards, home gardening is gradually rising. At present, domestic home ornamental plants are developing rapidly, and the application prospect of home gardening plant lighting is broad.
2, Cultivation of medicinal cannabis plants
This field belongs to the high-end planting field. The cultivation of medicinal plants, such as Cordyceps, clematis, Dendrobium cannabis (marijuana), etc. the products in these markets have higher economic value and are an industry with more applications of plant growing lighting at present. In particular, the legalization of marijuana cultivation in North America and some parts of Europe makes the application of LED grow lighting in this field in full swing. Some enterprises take this market as the main market and have already had high output value and income.
3, . Florescence lamps
As an essential tool to adjust flower flowering time in flower gardening industry, the earliest applied florescent lights are incandescent lamps. The subsequent energy-saving fluorescent lamps, with the industrialization of LED, more LED type florescent lamps have gradually replaced traditional lamps.
4, Indoor edible fungi planting
After the industrialized production of edible fungi, the indoor cultivation environment becomes a full dark room. Most of the fruiting bodies of edible fungi must be stimulated by light, and the quality of light will also affect the quality and overall yield of mushrooms. Indoor edible fungus planting has low demand for light and high planting density, so it needs close irradiation. As a cold source, LED has small size and random appearance. These characteristics are unmatched by other light sources, so it is especially suitable for this application field. China’s edible fungi industry ranks first in the world. With the industrialization of edible fungi, there is a considerable market scale for edible fungi related lighting.
5, Aquaculture, poultry breeding, algae culture
The characteristics of low driving voltage, low calorific value, selectable spectrum and high protection level of LED make the application of LED in this field have incomparable advantages over other lamps. At present, the application in aquaculture and poultry breeding has reached a certain scale and has been recognized by users. At present, the main market for the cultivation of special algae is still abroad. Some algae with special functions are widely used in the production of health food and drugs. Some research institutions hope to reduce the use of chemical and petrochemical energy through algae cultivation and conversion into bioenergy, which belongs to a promising industrial development direction.
6. Greenhouse seedling industry
With the development of facility agriculture, it is conservatively estimated that the light supplement market of domestic seedling industry will exceed 2 billion yuan in the next few years. The industry has high input-output and high acceptance of input; The industry also belongs to order production, and the product quality and delivery date have a great impact on the growers. Therefore, it also needs artificial lighting without being affected by the weather; It should also be mentioned that some products of the industry need grafting, and the amount of light should be controlled in the process of grafting healing. It also needs a certain amount of ultraviolet light to promote the healing effect. LED has unique advantages in this regard. Therefore, this industry can be used as the leading market for batch application of LED grow lighting.
7. Greenhouse plant growth
Greenhouse planting and light supplement are mainly used in North America and Northern Europe. It mainly maintains the stable growth of plants through light supplement, prolongs the fruiting period, improves the yield, and has a certain effect on improving the product quality. At present, China’s greenhouse lighting market is mainly concentrated in the facility agricultural production areas in central and North China, and its main application is still limited to the field of seedling raising and flower cultivation. The application of vegetable protected cultivation is still in a promotion and demonstration stage. In the future, the greenhouse lighting is mainly in the field of vegetable and fruit planting, and the overall market demand is expected to exceed 10 billion yuan / year.
