Abstract

The invention is applicable to the field of illumination technologies and provides an LED support. The LED support comprises a metal substrate and a plastic reflection cup arranged on the metal substrate. A protruding box dam for installation of an LED chip is arranged in a region defined by the plastic reflection cup. The box dam and the plastic reflection cup are integrally formed. The depth of the box dam is one-third to three times the thickness of the LED chip. The opening angle of each set of opposite inner side faces of the box dam is smaller than 120 degrees. Because the plastic reflection cup and the box dam are integrally formed on the metal substrate, the procedures are reduced, the production efficiency is improved, the LED support is not prone to deformation and stripping, the binding force between the plastic reflection cup and the metal substrate is enhanced, and the reliability of the LED chip is improved; the depth of the box dam is designed to be one-third to three times the thickness of the LED chip, and the opening angle of each set of opposite inner side faces of the box dam is limited below 120 degrees, so the side faces are prevented from absorbing light, the normal light emergence of the obverse sides is guaranteed, and the luminous efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of LED lighting, in particular to an LED bracket and an LED illuminant. Background technique

[0002] LED is one of the most widely used light sources at present. During the manufacturing process of LED, dams are usually made around the chip to facilitate the coating of fluorescent glue or packaging glue, or to prevent the sidewall of the chip from absorbing light. The existing dam manufacturing method is to make dams on the substrate before packaging, and then install the chips one by one in the middle of the dams. This method has complicated procedures, low efficiency, and increases costs. On the substrate, there is a hidden danger of deformation after long-term use, which affects the reliability of the LED.
