Stereoscopic light-emitting lamp sheet-based LED light source

Abstract

The invention discloses an LED light source based on a three-dimensional light-emitting lamp sheet, which includes transparent silica gel, heat-conducting insulating plastic and a packaging substrate connected up and down in an integrated manner. The packaging substrate is divided into a light-emitting area, a power supply packaging area, a stitch welding area, and a light-emitting area. It includes a substrate and a three-dimensional LED light source; the power supply packaging area includes a power supply that is located in a heat-conducting insulating plastic and is electrically connected to the three-dimensional LED light source. Production method; the upper part of the present invention uses a combination of three-dimensional LED light sheets and transparent silica gel, and at the same time, diffuser powder is added to the transparent silica gel to diffuse the light on the front and back into a three-dimensional light effect, and the silica gel can also improve the light efficiency. and heat dissipation; the second half of the present invention is a heat-conducting insulating plastic with a heat-conducting effect, which plays the role of heat conduction and heat dissipation.

Description

technical field [0001] The invention relates to the field of lighting fixtures, in particular to an LED light source based on a three-dimensional light-emitting lamp sheet and a preparation method thereof. Background technique [0002] Due to the characteristics of energy saving and high luminous efficiency, LED lamps have gradually become popular in the field of indoor and outdoor lighting. In addition to street lamps and household lighting, LED lamps have also begun to penetrate into refrigerator lights and car turn signals. The commonly used G9 type LED lights are often used in refrigerator lights, car turn signals, etc., but the brightness of the current G9 lights is generally limited, because increasing the brightness requires increasing power and increasing volume, but the size of the G9 light is quite small, so the brightness cannot Meet the requirements of some lighting occasions; at the same time, the LED light source is required to have sufficient luminous brightne...
