Problems solved by technology

This setting method can facilitate the replacement and maintenance of the LED control module in the after-sales service, but the disadvantage is that the LED control module occupies a large proportion in the narrow installation space of the car lamp, and the production of the bracket also leads to high costs. The cost, and the LED control module and the LED circuit board need to be connected by a wire harness, which complicates the assembly process, not only affects the production efficiency of the assembly line process, but also inevitably leads to the risk of poor wiring contact

Embodiment Construction

[0020] The invention discloses an integrated LED lighting unit, such as figure 1 As shown, it includes a radiator 1, an LED circuit board 2 and an LED control circuit board 3, the LED circuit board and the LED control circuit board are fixedly installed on the radiator, and the LED circuit board and the LED control circuit board maintain electrical connection. Owing to the omission of the dedicated bracket in the traditional LED control module, the space occupied by the entire LED lighting unit is reduced by at least 40%, which is conducive to meeting the development trend of miniaturization of vehicle lights.

[0021] The LED control circuit board is fixed on one side of the radiator, and the corresponding side of the radiator is made into a groove structure, and each component on the LED control circuit board is located in the groove structure in the installed state . A groove structure is provided on the heat sink to leave enough space for the components on the LED contro...

Abstract

The invention relates to an integrated type LED light-emitting unit. The unit comprises a radiator, an LED circuit board and an LED control circuit board, the LED circuit board and the LED control circuit board are both fixedly arranged on the radiator, the LED circuit board and the LED control circuit board are electrically connected in a bonding manner, the LED control circuit board is fixed toone side face of the radiator, the corresponding side of the radiator is arranged to be of a groove structure, under the mounting state, all elements in the LED control circuit board are arranged in agroove structure, and part of surfaces of part of elements on the LED control circuit board are attached to the groove bottom face of the groove structure. Occupied mounting space is obviously reduced, cost is reduced, poor wiring contact risks are avoided, and stability is high.

Description

technical field [0001] The invention relates to an LED light-emitting unit used for a car lamp, belonging to the technical field of car lighting. Background technique [0002] In the existing LED light-emitting units for car lights, the LED control circuit is often separately arranged on a PCB board and installed on the car light body through a special bracket. The PCB board where the LED control circuit is located and the corresponding bracket form a An external or built-in independent module is required, namely the LED control module. This setting method can facilitate the replacement and maintenance of the LED control module in the after-sales service, but the disadvantage is that the LED control module occupies a large proportion in the narrow installation space of the car lamp, and the production of the bracket also leads to high costs. The cost, and the LED control module and the LED circuit board need to be connected by a wire harness, which complicates the assembly ...
