Problems solved by technology

[0004] In the prior art, pressure welding is used to achieve electrical connection between the LED strip and the flexible circuit. However, due to the limited joint area, the joint strength is not enough to resist the pull of external force. Therefore, the LED lamp It is difficult to effectively solve the problem of poor contact between the strip and the flexible circuit or the problem that the flexible circuit falls off from the LED light strip

Abstract

The invention discloses a light-emitting diode module which comprises a light-emitting diode lamp strip and a flexible circuit. The light-emitting diode lamp strip comprises a circuit board and a plurality of light-emitting diode elements. The circuit board comprises a first surface, a second surface, a plurality of first connecting points, a plurality of second connecting points and an open slot. The light-emitting diode elements are configured on the first surface and electrically connected with the first connecting points. The flexible circuit penetrates the open slot and is electrically connected with the second connecting points, and the flexible circuit comprises a first joint part, a second joint part and a bent part. The first joint part comprises a plurality of three connecting points which are electrically connected with the second connecting points, and the first joint part is in contact with the first surface of the circuit board. The second joint part comprises a plurality of fourth connecting points which are electrically connected with the control circuit board. The bent part is connected between the first joint part and the second joint part and penetrates the open slot.

Description

technical field [0001] The present invention relates to a light emitting element, and in particular to a light emitting diode module (LED module). Background technique [0002] Since liquid crystal displays (LCDs) have advantages such as low-voltage operation, no radiation scattering, light weight, and small size, which cannot be achieved by displays made by conventional cathode ray tubes (CRTs), LCDs have been used It has become the main topic of display research in recent years, and it is constantly developing towards colorization. [0003] Since the liquid crystal display is a non-self-illuminating display, a backlight unit is required to provide the required light to achieve the display function. In recent years, with the improvement of environmental awareness, the light-emitting elements used in the backlight have gradually changed from cold cathode fluorescent lamps (CCFL) to more environmentally friendly light-emitting diode elements. When the LED element is used in...
