Integrated light source structure with wide-angle transmission

Abstract

The invention discloses an integrated light source structure with wide-angle transmission, which comprises a support, a heat radiation copper substrate, a PPA plastic reflective cup body, a blue light LED chip, gold threads, a transparent silica gel, an adhesive silica gel and a transparent light conductor, wherein an outer ring of the support is provided with the PPA plastic reflective cup body, the PPA reflective cup body and the heat radiation copper substrate are matched for constituting a cup cavity, the blue light LED chip is arranged on the surface of the heat radiation copper substrate through a silver adhesive solid crystal, electrodes are arranged on the heat radiation copper substrate on two sides of the blue light LED chip, the electrodes of the blue light LED chip are connected with the electrodes on the heat radiation copper substrate through gold threads, the transparent silica gel is packaged on the blue light LED chip, and the transparent light conductor is fixed on the upper surface of the transparent silica gel through the adhesive silica gel. The integrated light source structure can solve the problems that the light distribution of a lighting light source in the prior art is excessively centralized at the center during the use, the light distribution is seriously uneven and the like. The integrated light source structure is characterized by reasonable structure, low cost, large transmission angle, high light efficiency, great consistency of color temperature of the light source and the like, thereby being the very simple and practical lighting light source.

Description

technical field [0001] The invention relates to an illumination light source, in particular to a high-power integrated light source emitting at a wide angle. Background technique [0002] Traditional lighting mostly uses high-pressure sodium lamps, but with the development of technology, LED lamps have been widely used in various lighting fields due to their advantages such as high luminous efficiency, low power consumption, no need for high voltage, and high safety. When lighting large areas (such as headlights, street lights, tunnel lights, square lighting, factory lighting, park lights, etc.), the power of LED lights is relatively high at this time. The conventional high-power integrated light source packaging method is to place the chip in a matrix arrangement in the cup cavity of the bracket or the bottom of the bracket, and then use gold wires to connect the positive and negative electrodes of the chip and the positive and negative electrodes of the bracket, and then f...
