Stereoscopic light-emitting lamp sheet-based LED light source

Abstract

The invention discloses a stereoscopic light-emitting lamp sheet-based LED light source, which comprises a transparent silica gel, a heat-conducting insulating plastics and a packaging substrate, wherein the transparent silica gel, the heat-conducting insulating plastics and the packaging substrate are integrally connected in an up-and-down mode. The packaging substrate is divided into a light-emitting area, a power supply packaging area and a pin welding area. The light-emitting area comprises a substrate and a stereoscopic LED light-emitting light source. The power supply packaging area comprises a power supply arranged in the heat-conducting insulating plastics and electrically connected with the stereoscopic LED light-emitting light source. The invention further discloses a manufacturing method of the stereoscopic light-emitting lamp sheet-based LED light source. According to the invention, the upper half part of the stereoscopic light-emitting lamp sheet-based LED light source isformed through the combination of the stereoscopic LED lamp sheet and the transparent silica gel. Meanwhile, diffusion powders are added into the transparent silica gel, so that the light on the frontand back faces is diffused to form the stereoscopic light-emitting effect. Meanwhile, the silica gel can also improve the light efficiency and the heat dissipation performance. The lower half part ofthe stereoscopic light-emitting lamp sheet-based LED light source is formed by the heat-conducting insulating plastics good in heat conduction performance. Therefore, the effects of heat conduction and heat dissipation are achieved.

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...

Problems solved by technology

[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 brightness and small size. From the existing technology, it is quite difficult. One is the LED chip and many power supply materials such as rectifier tubes, voltage control How to effectively and fixedly connect the tube and the flow control tube together electrically; the second is the heat dissipation problem after being connected together; the above two problems are also the obstacles that hinder the large reduction in the size of the LED light source
