Technical Field
[0001] The utility model relates to the technical field of dimmable light par lamps, in particular to a dimmable light par lamp with high-efficiency heat dissipation. Background Art
[0002] Par light, also known as bowl-shaped aluminum reflector light, refers to the light source encapsulated in a reflective cup to ensure that the light is in a locked state, which can be used to illuminate the inside of a designated area to increase the light intensity inside the area.
[0003] A PAR lamp radiator with a publication number of CN212565352U is retrieved, comprising a heat dissipation frame and a heat-conducting metal cup, wherein the heat dissipation frame is separated into a power cavity and an LED cavity by a partition, and the partition is provided with a plurality of through holes connecting the power cavity and the LED cavity, and the heat-conducting metal cup is embedded in the LED cavity of the heat dissipation frame by a plastic-coated aluminum process, and the heat dissipation frame is made of heat-conducting plastic, and the heat-conducting metal cup comprises a cup bottom and a cup wall, and the LED cavity comprises an LED cavity bottom surface and an LED cavity side wall, and the height of the cup wall is lower than the height of the LED cavity side wall, and a blocking portion is provided at the end of the LED cavity side wall. The use of heat-conducting plastic as the material of the heat dissipation frame has the advantages of light material specific gravity, simple processing procedures, simple post-processing, good acid and alkali corrosion resistance, good heat dissipation effect, and long service life. The setting of the blocking portion has a simple structure, and does not require a fixed structure such as a buckle to limit. This structure can also improve the tightness of the heat-conducting metal cup and the LED cavity, improve the heat transfer efficiency, and prevent the two from being separated by external forces.
[0004] Existing par lights basically use air cooling for heat dissipation. Air cooling essentially uses a fan to take away the heat absorbed by the radiator. It has the advantages of relatively low price and easy installation, but it is highly dependent on the environment. For example, its heat dissipation performance will be greatly affected when the temperature rises or when overclocking. Utility Model Content
