As a further improvement of the utility model, it also includes a switching power supply, and the switching power supply is arranged in the large cavity.

As a further improvement of the utility model, it also includes a welding position fixing piece, and the welding position fixing piece is fixed at the end of the small cavity.

The beneficial effects of the utility model are as follows: the utility model has a simple and ingenious structure. By setting a right-angle projection lamp cup, the light emitted by the LED lamp can be projected in a straight line, reducing its brightness attenuated due to distance, so that the The brightness far away from the LED lamp can also meet the requirements of use, avoiding blindly increasing the power of the LED lamp, thereby reducing energy consumption and heat emission. By adopting a clever way of fixing the LED lamp base, the irradiation angle of the LED Can cover the largest range, so that the light is evenly distributed.

Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
