RBW mixed color plant growth LED lamp

Abstract

The invention discloses a RBW mixed color plant growth LED lamp. The LED lamp is formed by a rectangular LED unit or a triangular LED unit. The rectangular LED unit is formed by four lamp beads. The four lamp beads are respectively on four vertexes of the rectangular LED unit. The triangular LED unit is formed by three lamp beads. The three lamp beads are respectively on three vertexes of the triangular LED unit. The LED units are arranged tightly, and lamp beads are shared between adjacent units. The plant illuminating LED lamp greatly improves light mixing uniformity and working surface lighting effect, and realizes rectangular grading of specific spectrum. The LED lamp is aimed at open-air farmland, agricultural greenhouses, plant factories, and other plant growing places, and solves a problem of insufficient sunlight illuminance and has a function of supplementing light at night, and improves light quality needed by plant growth.

Description

technical field [0001] The invention belongs to LED lighting technology, in particular to an RBW mixed-color plant growth LED lamp. Background technique [0002] Photosynthesis is the most important chemical reaction on the earth and the basis for the survival of all organisms. Light is the driving force behind photosynthesis. Light quality and spectrum constitute important attributes of light. The wavelength range of the visible spectrum is 380-780, and the wavelength is shorter than 380nm The light is ultraviolet light, and the light longer than 780nm is far-infrared light. In the natural environment, the spectral composition of plants is constantly changing. There is more blue light on cloudy days, more red light in the morning and evening on sunny days, and strong light at noon. And it is white, and the weather spectrum components are changing from sunny to cloudy. At present, with the pollution of the atmosphere, the impact of smog and the continuous reduction of ozone ...

AI Technical Summary

Problems solved by technology

[0003] At present, LED light-emitting diodes have been widely concerned and recognized by all walks of life due to their advantages of low power consumption, environmental protection and energy saving. With great investment, many companies have developed integrated LED modules, but there are some deficiencies in the existing LED modules: the light quality of LED modules is single and the mixed light irradiation is uneven, which cannot meet the needs of plant growth; The group is a circular light distribution, which projects a circular light spot. The repeated area of ​​light distribution per square meter is high, and energy waste is serious; the substrate in the LED module uses an ordinary aluminum substrate with low reflectivity, which has the problem of low light efficiency and heat dissipation. High resistance, poor heat dissipation performance, resulting in greatly reduced reliability of LED modules

[0004] In view of the fixed wavelength of the above-mentioned plant growth lamps, which cannot adapt to the light quality of different plant growth stages, it is necessary to provide an energy-saving multi-light quality product to solve the problem of lighting or supplementary light in closed environments or natural environments, ensuring plant safety, healthy growth
