Problems solved by technology

The existence of the insulating layer will increase the heat dissipation channel of the LED light source, which will increase its thermal resistance and lead to unsatisfactory heat dissipation, and eventually cause the LED light source to have premature light decay due to poor heat dissipation
This seriously affects the light extraction efficiency and service life of the LED light source

Abstract

The invention provides an LED flexible board light source module, comprising an LED light source arranged on a flexible substrate, a radiating component on which the flexible substrate is arranged; and an electroconductive component which covers the flexible substrate and the radiating component and is electrically connected with the flexible substrate. An LED light source is mounted on the flexible substrate, then the flexible substrate is arranged on the radiating component, and the electroconductive component is used to be electrically connected with the flexible substrate, so that the LED light source dissipates heat through the radiating component, and realizes electrical conduction through the electroconductive component, thereby further realizing separation of electricity and heat, improving the radiating effect of the LED light source, effectively preventing the problem that light attenuation of the LED light source occurs too early due to poor heat dissipation, ensuring the luminous efficiency of the LED light source, and prolonging the service life of the LED light source.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to an LED flexible board light source module and a manufacturing method thereof. Background technique [0002] LED lamps have the advantages of long life and power saving, so they are more and more used in the field of lighting. [0003] At present, the common LED light source module usually installs the LED light source on the aluminum substrate, and then encapsulates the LED light source on the aluminum substrate through a light-transmitting package. [0004] Since the aluminum substrate in the existing LED light source module is both a heat dissipation component and a conductive component, it is often necessary to arrange a thick insulating layer and a circuit on the aluminum substrate at the same time. The existence of the insulating layer will increase the heat dissipation channel of the LED light source, thereby increasing its thermal resistance and resulting i...
