Lateral-entering red, green and blue COB light source device with light condensers and without light guide plate

Abstract

The invention discloses a lateral-entering red, green and blue COB light source device with light condensers and without a light guide plate. The light source device comprises the light condensers, supports, a diffusion light plate, a diffuse reflection backboard and frame plates, the light condensers are mounted on a frame at intervals, one support is fixed on the surface of each of two ends of the diffusion light plate, the frame plates are mounted on the supports, and the diffuse reflection backboard is mounted at the tops of the frame plates. Each light condenser mainly comprises a plurality of LED light sources, a light source support, an optical fiber lens, an outer reflection face and an inner reflection face, each optical fiber lens and the corresponding LED light sources are fixedat the surface center of the cylindrical light source support, each LED light source is positioned in the corresponding optical fiber lens, each outer reflection face is fixed at the surface edge ofthe corresponding light source support, and each inner reflection face is fixed on the surface of the corresponding optical fiber lens. By applying an LED surface light source with the light condensers and without the light guide plate, light effect is improved, the problem that the light guide plate is high in weight and cost is solved, and thermal warping of the light guide plate is avoided.

Description

technical field [0001] The invention belongs to the field of optics, and in particular relates to a side-entry red, green and blue COB light source device with a light concentrator without a light guide plate. Background technique [0002] With the rapid development of modern agriculture, land in developed areas is increasingly scarce, and traditional agriculture is declining. In order to meet the growing demand for food, it has become the general trend to follow the example of developed countries such as Japan and Germany to establish plant factories and vigorously develop vertical agriculture and modern agriculture. As a key part of plant growth, light plays an important role in the growth of plants, and LED plant light sources have emerged as the times require, but most of the LED light sources currently used in plant factories follow the optical structure of traditional LED lamps, such as The optical structure of LED spotlights, the optical structure of LED advertising l...

AI Technical Summary

Problems solved by technology

Aiming at the rapid development of modern agriculture and plant factories, the invention discloses a side-entry COB light source with a concentrator and without a light guide plate, and particularly relates to a light uniformity, which can illuminate plants in all directions and dissipate heat. The COB plant lighting source solution with excellent performance is used to solve the problems of unscientific design of plant lighting fixtures on the market, poor lighting effect in the plant cultivation plane, lack of multi-angle lighting for plants, and poor heat dissipation performance.
