Description

Technical Field

[0001] The utility model relates to the technical field of LED spotlights, in particular to an LED spotlight with heat dissipation fins. Background Technique

[0002] An LED spotlight is a spotlight that uses light-emitting diodes as the light source. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, consume a lot of electricity, cause the temperature of the illuminated environment to rise, and have a short service life. LED light sources are far superior to traditional lighting fixtures in terms of the light-emitting principle, energy conservation, and environmental protection.

[0003] At present, the heat dissipation design effect is not ideal, which affects the service life of the lamp. Since LEDs generate a large amount of heat during operation, if the heat cannot be dissipated in time, it will greatly affect the normal use of the lamp and easily cause potential safety hazards due to overheating.

[0004] For example, an LED spotlight disclosed in Chinese Patent CN219300553U. The LED spotlight includes a lamp frame. Sliding grooves are provided on the inner and outer sides of the bottom of the lamp frame. The lamp frame is rotatably connected with a rotating frame through the sliding grooves. The inner side of the rotating frame is rotatably connected with a mounting rod. A spotlight is fixedly connected to the middle of the mounting rod. A friction sleeve is fixedly connected to the top of the inner wall of the lamp frame. A friction pad is fixedly connected to the end of the spotlight. The advantages of the utility model are as follows: Through the cooperation of the sliding groove and the sliding ring, the rotating frame can rotate in the lamp frame, so as to adjust the angle of the spotlight when it is tilted, so that the spotlight can adjust the irradiation position according to needs, and through the lamp frame, the device can be directly installed inside the ceiling, making the installation of the spotlight more beautiful. Only by adjusting the angle of the spotlight during installation, each spotlight can irradiate to the required position. By restricting the friction coefficient between the rotating frame and the lamp frame, the rotating frame can be fixed under the action of friction.

[0005] However, this LED spotlight generates heat during use and lacks a corresponding heat dissipation mechanism to ensure the use effect of the LED spotlight and extend its service life.

[0006] Therefore, we propose an LED spotlight with heat dissipation fins to solve the above problems. Content of the Utility Model
