Luminaire heat dissipation structure and lamp having the same

The present invention relates to a heat dissipation structure, and more particularly to a heat dissipation structure of a high power lamp and a lamp having the same.

The heat sink design of the conventional light-emitting diode lamp is mainly to directly attach the LED light source to the cylindrical heat sink or the rectangular heat sink. Generally, the cylindrical heat sink is formed with a heat sink, and the radiating fins extend outward from the outer peripheral edge of the cylinder; in addition, the LED light source is attached to the axial plane of the cylinder. Furthermore, the rectangular heat sink is also formed with a heat sink, and the heat sinks arranged in a matrix form extend vertically outward from one side of the rectangular body; in addition, the LED light source is attached to the other side of the rectangular body.

In order to prevent the overall volume of the heat sink from being excessively large, the extension of the radiating fins of the cylindrical heat sink tends to reduce the area of the axial end faces, so that most of the LEDs are arranged on the narrow cylindrical end faces, which will cause the lamps to be The lighting area is reduced and the heat source is concentrated to reduce heat dissipation efficiency. On the other hand, the heat sink of the rectangular heat sink has a vertical heat transfer surface, and the heat dissipation channels formed by the heat sink are oriented in the same direction. Therefore, although the rectangular heat sink has a large heat transfer area, the heat dissipation channel in one direction is disposed. It may be caused by poor ventilation in the environment. In addition, the rectangular heat sink is not easy to match with the luminaire and dissipates heat.

Furthermore, if the existing LED lamp has the need to adjust the illumination angle, it is necessary to additionally provide a pivotable seat body, and pivot the LED module with the heat sink to the seat body, but It will increase the assembly parts and processes and cause inconvenience. Moreover, since the luminaires are used in different occasions, such as a projection lamp placed at a high place, a lens is usually installed in the lampshade to generate a concentrated light source; however, the thickness of the luminaire due to the necessary thickness of the lens The dramatic increase in the number of fixtures placed in high places is potentially dangerous.
