[0002] In the existing monitoring camera device, for example, the common infrared lamp monitoring camera, the disc-shaped LED infrared lamp is usually fixed directly on the circuit board, and then the aluminum light collecting plate is sleeved on the cup body of each LED infrared lamp for gathering the light emitted by the LED infrared lamp into a certain range for emission, however, the LED infrared lamp generates a large amount of heat when working, and the current heat dissipation mode has many defects, on the one hand, the heat generated by the LED infrared lamp is mainly dissipated outward through the two pins, and the two pins are welded on the circuit board. Since the circuit board is formed by covering copper on the insulating substrate, its heat dissipation capacity is poor, and it is difficult to quickly conduct the heat accumulated in the LED infrared lamp pin to the outside, on the other hand, the heat on the two pins of the LED infrared lamp cannot be efficiently conducted to the light collecting plate, and there is a heat dissipation dead angle, which causes the heat generated by the LED infrared lamp to be unable to dissipate to the outside environment in time, so that the lamp panel is always at a high working temperature, which not only shortens the working life of the lamp panel, but also reduces the working stability of the monitoring camera, the heat dissipation effect is poor, and it is difficult to meet the increasing monitoring demand.
