Problems solved by technology

The light source used for indoor plant growth is mainly incandescent lamp or fluorescent light source, which is also a relatively mature technology. However, the light wavelength of the commonly used method is not completely suitable for the growth of plants.
The problems that exist at present are: (1) the existing method irradiation is only the method of simulating sunlight, and the wavelength of the light cannot be fully controlled; (2) only light irradiation, but neither automatic temperature measurement nor control of the temperature of the growth chamber ; (3) Only incandescent lamps or fluorescent light sources, no fixed wavelength and selectable wavelength light sources

Description

technical field [0001] The invention specifically relates to the fields of electronics and biotechnology, and belongs to the technology of automatic instruments and devices; in particular, it is a plant growth control device with a high-power light-emitting diode light source. Background technique [0002] Chinese patent application CN002547619 discloses that red light-emitting diodes (LEDs) have a good promoting effect on plant growth, and are especially suitable for indoor plant growth occasions where light is insufficient. The light sources used for indoor plant growth are mainly incandescent lamps or fluorescent light sources, which are also relatively mature technologies, but the light wavelengths of the commonly used methods are not completely suitable for the growth of plants. The problems that exist at present are: (1) the existing method irradiation is only the method of simulating sunlight, and the wavelength of the light cannot be ful...
