Lateral type LED plant lighting panel light with light guide plate

Abstract

The invention relates to a lateral type LED plant lighting panel light with a light guide plate, and belongs to the technical field of plant illuminating lights. The lateral type LED plant lighting panel light comprises a plurality of shells connected end to end in sequence, strip-shaped LED light source plates, a light-emitting panel, the light guide plate and a reflective plate, wherein the light-emitting panel, the light guide plate and the reflector plate are stacked in sequence. Every two adjacent shells are connected together by corner connecting blocks, and the shells comprise integrally formed bottom plates and side plates arranged on both sides of the bottom plates. The LED light source plates abut against the bottom plates, and the edge of the reflective plate abuts against the side plates. The side plates of all the shells jointly support the reflective plate, and the light-emitting direction of the LED light source plates faces towards the side surface of the light guide plate. The lateral type LED plant lighting panel light with the light guide plate has a good light mixing effect.

Description

technical field [0001] The invention relates to the technical field of plant lighting lamps, in particular to a side-entry LED plant lighting flat panel lamp with a light guide plate. Background technique [0002] In recent years, due to the continuous improvement of people's living standards, the demand for off-season vegetables and other crops has increased sharply, and the quality requirements for vegetables have also increased accordingly, followed by the vigorous development of plant factories and facility cultivation. The light environment is one of the important physical environmental factors that are indispensable for plant growth and development. Through the adjustment of light quality, the flowering and fruiting of crops can be artificially controlled, the growth cycle of plants can be controlled, and the plant height and nutrient content of plants can be controlled. LED light sources have rich wavelength types, which coincide with the spectral range of plant photo...

Problems solved by technology

However, since the direct-type LED plant light source is directly installed on the base plate, in order to obtain ideal uniformity, the light mixing distance must be increased, which requires an increase in the thickness of the lamp, and the current direct-type LED plant light source array Rectangular grid arrays are mostly used, and the density of light sources is high, resulting in high power consumption. In the market environment of pursuing lightness, lightness and energy saving, these two shortcomings limit the development of direct-lit LED plant growth lights

The traditional direct-type plant lighting rectangular array has a large proportion of "blind area" of mixed light, and the "blind area" of triangular array is small but has the disadvantage of high light source density.
