Abstract

The invention discloses a flexible circuit board convenient for efficient heat dissipation and mainly used in a high-power LED illumination array, belonging to the semiconductor illumination technical field. The flexible circuit board of an LED illumination array is characterized in that: the circuit board is provided with a flexible substrate, a connection circuit, an insulating film-covered layer, a heat-conducting rubber pad and an LED light source; the connection circuit is arranged on the surface of the flexible substrate; the surfaces of the flexible substrate and the connection circuit are covered with the insulating film-covered layer to form a circuit board module; the LED light source is packaged inside the circuit board module in an array mode; the bottom surface of the flexible substrate is adhered to the surface of the heat-conducting rubber pad. Therefore, the entire flexible circuit board module has certain elasticity and flexibility and can adapt to bending, twisting and crimp deformation of certain strength; moreover, the invention can also be arranged on non-flat surfaces not more than a certain curvature such as a cylindrical surface or a spherical surface. The invention has wider application scope, better heat dissipation performance, less production cost, convenient installation and substantially increased production efficiency.

Description

technical field

[0001] The invention discloses a flexible circuit board which is convenient for high-efficiency heat dissipation and is mainly used in high-power LED lighting arrays, and belongs to the technical field of semiconductor lighting. Background technique

[0002] LED (light-emitting diode) technology began in the late 1960s. After half a century of rapid development, LED light sources, especially high-power and bright LED light sources, are known for their high luminous efficiency, small size, long service life, and environmental protection and energy saving. And many other advantages, it occupies an important position in the lighting source, and it is still developing rapidly.

[0003] In the original LED lighting products, the LED light source was directly packaged inside the lamp body. Because the lamp body material is mostly conductive metal, the insulation protection of the circuit must be considered when connecting the circuit, which is time-consuming and la...
