LED plant growth insecticidal lamp based on mixed spectrum

Abstract

The invention discloses an LED mixed spectrum plant growth insecticidal lamp and belongs to the field of plant LED illumination. The lamp comprises an LED lamp dot matrix, a single chip microcomputer control system, a shell and an insecticidal power grid. According to the LED mixed spectrum plant growth insecticidal lamp, power distribution of a power source which specific mosquitoes are fond of is obtained by experiments, through a specific algorithm, proportions in a target light source of three primary colors of red, green and blue can be obtained, the duty ratio of three path PWM waves sent by the single chip microcomputer control system is changed, and therefore electric current driven by LED constant current can be changed, the illumination power of an LED is changed correspondingly, and the target light source can be obtained. The technical problems can be solved that a common plant insecticidal lamp is single in color and does certain harm to both beneficial insects and the human body, and certain guidance for pest killing by plants and optimization is provided.

Description

technical field [0001] The invention relates to a plant growth insecticidal lamp based on LED mixed light, which belongs to the field of plant LED lighting. Background technique [0002] Every plant has a preferred light source, and the same is true for insects, which have their own preferred light sources. At present, there are several hypotheses about the phototaxis of insects, such as the light-directed behavior hypothesis, the biological antenna hypothesis, and the light interference hypothesis. Although there is no definite theoretical basis, the wavelength range of the light source preferred by a specific insect can be obtained through experiments. At present, the vast majority of plant insecticidal lamps on the market use ultraviolet rays to attract mosquitoes. A single light source is not effective in attracting mosquitoes. It will kill some beneficial insects by mistake during use, and prolonged exposure to ultraviolet rays will cause It will cause certain damage ...

Problems solved by technology

Although there is no definite theoretical basis, the wavelength range of the light source preferred by a specific insect can be obtained through experiments

At present, the vast majority of plant insecticidal lamps on the market use ultraviolet rays to attract mosquitoes. A single light source is not effective in attracting mosquitoes. It will kill some beneficial insects by mistake during use, and prolonged exposure to ultraviolet rays will cause Cause certain damage to the skin of the human body

To sum up, the ultraviolet insecticidal lamps sold on the market are not a good choice
