Abstract

A high-light effect and high-power integrated LED with even light spots is mainly composed of a support, gold wires and a plurality of wafers. The wafers are fixed on the support and are connected through the gold wires. The wafers at the two ends are connected with the positive electrode of the support and the negative electrode of the support through the gold wires, the wafers are evenly distributed on the surface of the support in an S-shaped structure mode, and a bowl cup of the support is filled with fluorescence glue. According to the high-light effect and high-power integrated LED with the even light spots, the S-type crystal solid wire method is adopted, the wafers are evenly distributed on the surface of the support, the bowl cup of the support is filled with the fluorescence glue, and therefore an LED can emit even light without a light spot, the excitation efficiency of fluorescent powder is higher, and the brightness is greatly improved. Due to the fact that the wafers are arranged in a scattered mode, the heat dissipation of the high-light effect and high-power integrated LED is better, and the quality reliability is enhanced.

Description

technical field [0001] The invention relates to the technical field of lighting fixtures, in particular to a high-efficiency and high-power integrated LED with uniform light spots. Background technique [0002] At present, the main structure of high-power integrated LED is composed of: bracket, chip, gold wire, phosphor (only available in white light), and AB glue, such as figure 1 As shown, a plurality of LED chips (4) are fixed on the bracket (1) by silver glue, the LED chips (4) are connected to each other by gold wires (3), and the LED chips (4) at both ends are connected by gold wires (3) It is connected to the support positive pole 5 and the support negative pole 6 of the support (1), wherein the cup of the support (1) is provided with silica gel filled between a plurality of LED chips (4), and wraps the gold wire (3). The structure of the LED can prevent the damage of some gold wires or LED chips inside the LED integrated light source, and solve the phenomenon that t...
