Plant growth light supplementing lamp

Abstract

The embodiment of the invention provides a plant growth light supplementing lamp, and belongs to the technical field of plant growth and light supplementing. According to the invention, the problems of non-adjustable spectral proportion, low using efficiency, high cost, single function and the like for existing plant growth light supplementing lamps can be solved. The plant growth light supplementing lamp comprises a spectrum adjustment control circuit and an LED lamp bead sequence. The LED lamp bead sequence comprises a blue light source, a red light source, a white light source, an infraredlight source and an ultraviolet light source. The spectrum adjustment control circuit comprises at least two control branches. The LED lamp bead sequence is driven by each of the two control branchesto emit light in the form of a lamp bead combination formed by lamp beads arranged according to a certain proportion and set in different colors. The plant growth light supplementing lamp is low in cost, adjustable in spectral proportion and applicable to various plant growth requirements. The plant growth light supplementing lamp is mainly used for providing a required light spectrum for plants in the plant growth process, and promoting photosynthesis to assist the plant growth.

Description

technical field [0001] The invention belongs to the technical field of supplementary light for plants, and in particular relates to a multifunctional plant growth supplementary light with adjustable spectrum ratio. Background technique [0002] There are roughly two types of existing plant growth supplementary light devices: one is a fixed ratio of red and blue, and a fixed brightness. This kind of plant growth supplementary light has a single function and can only be used for the growth needs of one plant; the other is The ratio adjustment under certain conditions is achieved by adjusting the intensity of one of the bands of light. This adjustment is mostly realized through PWM dimming, which reduces the luminous efficiency of the lamp beads. At the same time, PWM dimming will bring serious stroboscopic problems. , not only causes a great waste of resources, but also reduces the light supplement effect, and also makes the manufacturing cost high, which leads to the fact tha...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of high cost, poor effect, non-adjustable spectral ratio and only one kind of plant growth supplementary light for a single product, the present invention provides a low-cost, adjustable spectral ratio It is a multi-functional plant fill light that can be adjusted and can be applied to a variety of plant fill lights. It has the characteristics of simple structure, low manufacturing cost, and easy large-scale promotion.
