Solar energy driven plant growth lamp

Abstract

The invention provides a plant growth lamp driven by solar energy, in particular to a plant growth lamp with specific spectrum wavelength particularly designed for growing development of plant, belonging to agricultural engineering technical field. The invention discloses a plant growth lamp driven by solar energy, comprising a solar battery module, a light source panel consisting of three LED semiconductor light sources, and a light quality regulating and controlling device, wherein, the light source panel consists of a red LED semiconductor light source with wavelength of 630nm, a blue LED semiconductor light source with wavelength of 460nm and a far-red LED semiconductor light source with wavelength of 730nm which are in cross combined distribution. The LED light sources have an improving function to the growth of plant, can reduce the temperature increment brought by heating of a common light source, and can reduce manufacturing cost; the LED light sources also can sufficiently use the solar energy to provide energy for plant production under man-made environment, and can reduce dependence to conventional energy and electric energy.

Description

A solar powered grow light technical field The invention is an artificial light source device, specifically, a plant growth lamp specially designed for plant growth driven by solar energy and having a specific spectral wavelength. Background technique Plants can feel light with a wavelength of 280-800nm, but the absorption of light by plants is not in the whole band, but mainly concentrated in the blue-violet light area of ​​400-460nm and the red-orange light area of ​​600-700nm. The spectrum of fluorescent lamps widely used at this stage is mainly between 450 and 580nm, and less than 10% of its spectral energy is used by plants for photosynthesis, and a considerable amount of energy is transferred to the environment in the form of thermal effect, which produces a large amount of heat and causes environmental pollution. The temperature rises. In order to maintain the temperature required for plant growth, cooling measures must be taken, artificially increasing production ...
