Abstract

The invention relates to the technical field of LED lighting lamps, particularly to a high-power LED-COB optical engine device. An optical engine module comprises radiators 1, COB light sources 2, substrates 3 and a constant-temperature driving power supply 4, wherein the constant-temperature driving power supply 4 and the COB light sources 2 are separately mounted on the substrate I 31 and the substrate II 32; the substrate I 31 and the substrate II 32 are arranged up and down; and the radiators I are cooling fins. The high-power LED-COB optical engine device has the characteristics that the cooling fins are arranged on the substrate I 31 and the substrate II 32 separately, clearances are formed between interfaces of the substrates 3 and the cooling fins, a contact surface is coated with colloidal heat conducting silicone grease with relatively high heat conducting property, the actual contact area is increased, the heat dissipation effect is further strengthened, change of color rendering indexes due to change of color temperature is avoided, and the service life of the high-power LED-COB optical engine device is directly affected by too high temperature.

Description

technical field [0001] The invention relates to the technical field of LED lighting fixtures, in particular to a high-power LED-COB light engine device. Background technique [0002] The COB light source module can save the primary packaging cost of LED, the production cost of the light engine module and the secondary light distribution cost in the application. In the lighting system with the same function, the actual calculation can reduce the cost of the light source by about 30%. The application and promotion of lighting is of great significance. [0003] Whether the color temperature distribution of high-power LED-COB lamps is uniform will directly affect the lighting effect; moreover, color temperature and color rendering index are interrelated, and changes in color temperature will cause changes in color rendering index, and excessive temperature rise will also directly affect high-power LEDs. -The service life of the COB lamp.
