LED synchronous red-blue light panel light source used for promoting plant growth

Abstract

An LED synchronous red-blue light panel light source used for promoting plant growth is composed of a high reflection panel, blue light LED light bars, a rare earth luminous panel, a light guiding board and an aluminum frame. The aluminum frame is a rectangular, the blue light LED light bars and the middle of the inner side face of the aluminum frame are fixed, the four side faces of the cuboid light guiding board, are connected with the blue light LED light bars around the cuboid light guiding board respectively, and the high reflection panel and the rare earth luminous panel adhere to the upper face and the lower face of the aluminum frame in a sealing mode. The LED synchronous red-blue light panel light source has the advantages that the structure is simple, implementation is easy, LED conversion is achieved from a traditional point light source to an area light source, the spectrum is wide, brightness is high, light colors are even, the capacity of damp and hot resistance is high, and service life is long; the full width at half maximum of an emitted red light peak is approximate to 70nm and is closer to red light in natural light, the irradiance proportion of red light and blue light is adjustable, coverage can be effectively performed on the absorption spectra of plants so that requirements of plant growth can be met, and the LED synchronous red-blue light panel light source can be widely applied to an intelligent plant factory and the fields of perpendicular planting, tissue culture seedling growth, home gardening and others.

Description

technical field [0001] The invention belongs to the field of semiconductor optoelectronic materials and devices, in particular to an LED synchronous red and blue flat panel light source for promoting plant growth. Background technique [0002] Light plays a very important role in the growth of plants. Without light, photosynthesis cannot proceed. The light needed for the growth and development of plants usually depends on sunlight, but the industrial production of vegetables, flowers and other economic crops, tissue culture and propagation of test-tube seedlings also need artificial light sources for supplementary light. In late autumn, winter, spring and other seasons, the light time is short, and there is a serious lack of light in the greenhouse, so the crops cannot grow normally. In the event of continuous cloudy, foggy, rainy and snowy days, the impact on crop growth will be more serious. At the same time, a large number of studies have shown that different wavelength...

Problems solved by technology

Scientific research has confirmed that the light for the growth of most plants is mainly concentrated in the red and blue light bands. The effective spectrum of photosynthesis is composed of red light and blue light, which covers the absorption spectrum of the light-harvesting pigment antenna in the plant leaves. It is currently used in the market The red and blue light artificial light source for plant supplementary lighting is mainly composed of blue LED lamp beads with a peak wavelength of about 440-470 nm and red LED lamp beads with a red peak wavelength of about 610-630 nm. The spectrum is narrow and cannot effectively cover plants. The absorption spectrum cannot meet the needs of plant growth. These LED lamp beads are point light sources, and the light color is uneven in space. Use, it is easy to cause the deterioration and light decay of LED lamps
