Abstract

The present invention relates to a high-power LED light source module, related to the technical field of semiconductor lightings. The high-power LED light source module comprises a metal substrate. A resin insulating layer and a high thermal-conductivity insulating layer are formed on the metal substrate. Also, a metal pattern circuit is formed on the resin insulating layer. A metal circuit and either a high-power LED light bulb or chip are formed on the high thermal-conductivity insulating layer. The metal pattern circuit on the resin insulating layer and the metal circuit on the high thermal-conductivity insulating layer are connected via a metal connector. Employment of the high-power LED light source module of the present invention not only involves relatively reduced costs but also provides the advantages of high thermal conductivity, resistance against aging, resistance against puncturing, and reliable performance.

Description

technical field [0001] The invention belongs to the technical field of semiconductor lighting, and more specifically, the invention relates to a light source module which is convenient for high-efficiency heat dissipation and is applied to high-power LEDs. Background technique [0002] LED (Light Emitting Diode) technology began in the late 1960s. After about half a century of development, as a new type of light source, it has been obtained due to its incomparable advantages such as energy saving, environmental protection, long life, and fast start-up speed. unprecedented development. High-power LED solid-state lighting is the most important lighting revolution since the invention of the incandescent lamp. Semiconductor LED materials can directly convert electrical energy into light energy, which is the biggest difference from traditional lighting sources. It has high luminous efficiency and energy consumption is only one-eighth of ordinary incandescent lamps; and it has a ...
