Plant growth lamp of high-efficiency high-power LED light source

Abstract

The invention provides a plant growth light with a high-efficiency high-power LED as a light source, which comprises a support, a constant-current power source, a control circuit and an LED light source. The LED light source adopts 1 to 10 red light LED light-emitting diodes and blue light LED light-emitting diodes of between 1 and 5 watts and is formed by packaging of red and blue single chips or composite chips, the LED light source is adhered on an aluminum-based printed circuit board through a high thermally conductive adhesive, the center of the LED light source is provided with a light-emitting lens, the aluminum-based printed circuit board is fixedly connected with a flat panel radiator, and two sides of the flat panel radiator have high-efficiency reflecting shades. The plant growth light has low power consumption, long service life of the light source, higher light efficiency and good application prospect, and is capable of effectively controlling illumination required by the plant growth and controlling optical wavelength, duty ratio and frequency quantitively.

Description

technical field [0001] The invention relates to a plant growth lamp, in particular to a plant growth lamp using a high-brightness light-emitting diode (LED) above 1W as an illumination light source, and belongs to the technical field of semiconductor lighting and plant cultivation appliances. Background technique [0002] The growth of plants needs the sun, but modern science can make plants grow better in places without the sun. People have mastered the internal principle of plants' need for the sun, which is the photosynthesis of leaves. When photosynthesis of leaves requires the excitation of external photons The entire photosynthetic process can be completed, and the sun's rays are an energy supply process excited by photons. Artificially creating light sources can also allow plants to complete the photosynthetic process. Modern gardening or plant factories are combined with supplementary light technology or complete artificial light technology. [0003] At present, the...

Problems solved by technology

The cold light source has the effect of high light efficiency, energy saving and electricity saving. For example, the plant growth lamp of the fluorescent light source mainly relies on the fluorescent lamp and the filter to obtain the required wavelength and optical density, which cannot be controlled accurately quantitatively, and the quantitative parameters cannot be set arbitrarily as needed. combination, restricting the in-depth study of photobiology
