Integrated COB light source with power drive

Abstract

The invention discloses an integrated COB light source with a power drive. The integrated COB light source comprises an aluminum substrate. A light source module and a power drive module are arranged on the aluminum substrate. The light source module comprises a plurality of LED chip sets. The power drive module is arranged around the light source module, and has the same number of drive control ends as the LED chip sets. The LED chip sets are covered with fluorescent powder. The power drive module lights up the corresponding LED chip set according to the change of input voltage. By adopting the aluminum substrate, heat generated by the light source and electronic components can be dissipated effectively, and the heat dissipation performance is good. As the light source module and the power drive module are arranged on the same substrate, power source and light source mismatch is avoided. Moreover, the assembly process is simplified, the product yield is improved, and the cost of manpower and material resources is reduced.

Description

technical field [0001] The invention relates to LED lighting products, in particular to an integrated COB light source driven by a power supply. Background technique [0002] In the current COB lighting scheme, in order to drive the COB module to emit light, it is necessary to add a driving circuit to generate a suitable driving current and voltage. When the COB module continues to emit light, in the current general lamp structure, the COB module light source and The driving circuit part is isolated and assembled separately. Because each component is constructed independently, both the COB module and the drive circuit require separate substrates, resulting in waste of materials. In addition, the lamp assembly process is complicated, the work efficiency is low, and the labor cost is high. In addition, the COB light source and driving power must match, otherwise the lamp will fail. In the assembly process, wiring errors often occur, and repeated disassembly and assembly are ...
