Problems solved by technology

[0004] Therefore, the performance of the LED bracket directly determines the reliability of the LED light source product. At present, the conventional EMC LED brackets on the market have airtightness problems. Elements and other substances enter the package through the gap between the EMC adhesive and the copper substrate, resulting in blackening of the product, degradation of optical performance, and serious quality defects of dead lights.
[0005] like figure 1 , figure 2 As shown, external water vapor, halogen elements and other substances enter the package body through the gap between the EMC adhesive 2 and the copper substrate 1, resulting in blackening of the product, degradation of optical performance, and serious quality defects such as dead lights.
At the same time, due to the large difference in thermal expansion coefficient between the EMC adhesive material and the copper substrate, after the injection molding is completed, the material shrinks and gaps appear

Abstract

The invention relates to a high-sealing performance LED support and belongs to the LED support technical field. The high-sealing performance LED support includes a copper substrate, an EMC adhesive material and an internal reinforced EMC adhesive material; and the upper surface and lower surface of the copper substrate are respectively provided with the EMC adhesive material and the internal reinforced EMC adhesive material. The high-sealing performance LED support has the advantages of improved air tightness, prolonged long service life, convenient use and structure simple.

Description

technical field [0001] The invention relates to the technical field of LED brackets, in particular to a high-sealing LED bracket. Background technique [0002] The homogeneous competition in the current LED market is serious, and the quality of light sources is also uneven. Frequent "quality gates" have seriously affected consumers' confidence in LED lighting. The market is eagerly looking forward to a significant effect on the existing LED light source technology. Fully upgraded and remodeled. In view of the two prominent shortcomings of high cost and high heat in current LED lighting, the market adopts new materials and new structures for light source packaging, that is, EMC LED packaging. LED light source technology has achieved a leap-forward progress, which has completely solved its worries about entering the field of general lighting. [0003] However, as the carrier of light source realization, EMC LED bracket plays a vital role in the development of LED. The packa...
