LED market lighting for horticultural plants

At the same time, scientists continue to try to match the monochromatic spectrum with different plants and stages of growth, MAURY WRIGHT reported that the market for LED lighting and solid-state products for horticultural applications is expanding.

Horticultural studies have determined that some relatively narrow spectral bands of radiation can promote chlorophyll absorption in plants, thereby promoting photosynthesis processes. Packaging LED manufacturers and solid-state lighting (SSL) finished product manufacturers are moving, so want to get a share from a fast-growing market. At the same time, the researchers continued their efforts to understand how other wavelengths could further increase the productivity of greenhouses and indoor commercial farms.

The mix between LED lighting and commercial growers of flowers and vegetables is natural. Whether it is in the greenhouse needs to fill light, or completely rely on artificial light indoor environment, gardening lighting electricity is a major cost of the farm. Energy-efficient solid-state lighting (SSL) products have promised to reduce electricity costs from the start.

However, research on how "a particular spectral band mainly affects the different stages of plant growth cycles" makes LED more suitable for this application. Broad-spectrum light sources, such as metal halide lamps, are essentially wasting energy in the production of partial spectral bands, such as green light, and current studies have shown that green light has at least no benefit to plant growth. In contrast, the monochromatic nature of LEDs means that solid-state lighting manufacturers can produce lamps that produce only the spectral energy required by the plant, thereby increasing energy efficiency.
