Single color LED lamp with multiple color structure of the implementation of a light guide Panel

摘要

The present invention relates to a structure of a light guide plate in which a multi-color LED is implemented using a single color LED lamp, and more particularly, a light guide plate 10 having an accommodating groove 11 formed on an inner side of a tip portion thereof so that the light source body is embedded therein. The LED unit 20 includes a plurality of LED lamps 21, which are light source bodies for irradiating light into the light guide plate 10, and a PCB 22 for mounting the LED lamps 21 on an upper surface thereof. And an acrylic plate 30 formed of a transparent material so as to be transmitted to the back of the light guide plate 10 so that the light refracted from the front is transmitted. The color of the light refracted from the front surface is attached to the front of the acrylic plate 30. Consists of a color sheet 40 to change the shape, and has a transparent acrylic plate that is irradiated by the light is refracted to the rear so as to reduce the production cost by simplifying the overall structure, the desired color when manufacturing It is equipped with a color sheet for changing the color of the light refracted to the back so that it can be changed, and the diffusion refractive dot groove which is a groove that is narrowed at a predetermined angle so that the light irradiated from the LED lamp having the straightness can be easily diffused and refracted Diffusion coating part coated with diffusion coating liquid is formed to increase the diffusivity and increase the advertising ability, and implement a multi-color with a single LED lamp having a heat sink for cooling the heat generated inside to prevent failure due to heat It relates to a light guide plate.
