Abstract

The utility model discloses a high-power LED (Light-Emitting Diode) radiating member. The high-power LED radiating member comprises an outer shell which is composed of an LED mounting sole plate and radiating LED packaging sides, wherein the outer shell is internally provided with a power circuit base plate connected with a power interface; four sides of the power circuit base plate are packaged with a heat-transmitting filling material; and a flange is arranged between the filling material and the outer shell. As the four sides of the power circuit base plate are packaged with the heat-transmitting insulating filling material, the heat-transmitting filling material and the radiating LED packaging sides compose a radiating system of the LED. Therefore, the high-power LED radiating member, disclosed by the utility model, improves use safety of a high-power LED device efficiently.

Description

A kind of great power LED radiating element

Technical field

The utility model belongs to the LED lighting technical field, relates to a kind of high-power LED radiator spare.

Background technology

Advantages such as light emitting diode (LED) is the semiconductor light sources of environmental type, has low energy consumption, long-life, and volume is little, and structure is firm, and good directionality, response are fast, and be radiationless.But high-power and high-luminance LED product distribute heat is very big, and the chip core temperature is up to 180 ℃.The photochromic performance of LED can decay at short notice, the infringement life-span, even cause phenomenon such as dead lamp.Heat conduction and heat radiation material commonly used mainly is aluminium base or aluminium alloy lamp bracket, but because involve great expense, and self specific heat is less, the not good application that waits the restriction great power LED of heat-sinking capability.

The utility model content

The technical problem that the utility model solves is to provide a kind of high-power LED radiator spare, can improve the rate of heat dispation of LED, expansion high-power LED encapsulation mode.

The utility model is to realize through following technical scheme:

A kind of high-power LED radiator spare; Comprise that LED installs the shell of the LED encapsulation limit formation of base plate and heat radiation; Be provided with the LED power supply circuit board that is connected with power interface in the shell, be packaged with the packing material of heat transfer around the LED power supply circuit board, be provided with flange between packing material and the shell.

Described LED encapsulation limit is to LED the curved surface that base plate expands gradually to be installed by power interface.

Compared with prior art, the utlity model has following beneficial technical effects:

The high-power LED radiator spare that the utility model provides; Packing material through the insulation of encapsulation heat transfer around the power circuit base plate; The packing material of this heat transfer and the LED of heat radiation encapsulation limit have constituted the heat radiation system of LED, effectively promote the safety in utilization of great power LED device.Simultaneously can expand the high-power LED encapsulation mode, more photochromic solution is provided, help the great power LED miniaturization of devices, lightweight.
