Abstract

The invention discloses an optical engine module based on a low-heat-resistance heat dissipation technology. The optical engine module comprises an LED wafer, a circuit layer, an insulation layer and an aluminum substrate, wherein the LED wafer, the circuit layer, the insulation layer and the aluminum substrate are combined in sequence and fixedly connected. The optical engine module is characterized in that a plurality of heat dissipation holes are formed in the circuit layer; a positive electrode bonding pad and a negative electrode bonding pad are arranged on two sides of the lower end of the aluminum substrate respectively; a groove is formed in the middle of the lower end of the aluminum substrate; a copper foil layer is fixedly arranged in the groove; a flange is arranged on the copper foil layer; and a fluorescent layer formed by fluorescent powder colloids is arranged on the LED wafer. The optical engine module is simple in structure and excellent in heat conduction performance.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a light engine module of a lamp. Background technique [0002] As an emerging energy-saving lamp, LED is widely used in the lighting field because of its low energy consumption, long life, economical and environmental protection, and the light engine is particularly important as an accessory in the LED lamp. It is used for the light emitted by the flashlight Whiter, more durable, focusable, and inexpensive, it is favored by users. However, due to the lack of thermal conductivity of most existing LED light engines, the heat of the light engines cannot be dissipated in a timely and comprehensive manner directly, resulting in poor heat dissipation performance of existing LED lamps and short service life. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a light engine module with simple structure and excellent thermal conductivi...
