Description

Socket radiator for lamps

This creation relates to a heat sink, especially a socket type heat sink for a luminaire.

The application of Light-Emitting Diode (LED) in the illumination of lamps has become an irresistible trend. The LEDs have the advantages of high brightness, power saving and long service life, and are generally favored by the market. The module composed of the polar body can generate high power, so the light-emitting diode has become one of the main light sources in line with the theme of energy saving and environmental protection.

However, with the higher power and brightness of the light-emitting diode, the higher the relative heat generated, if it can not effectively dissipate the accumulated heat, in addition to affecting the light-emitting quality of the light-emitting diode, it may cause light when it is serious. The damage of the diode is shortened and the service life of the light-emitting diode is shortened. Therefore, the good heat dissipation design can make the light-emitting diode exhibit better light-emitting quality and prolong the service life of the light-emitting diode. Moreover, most of the heat sinks used in lamps and lanterns in the past are designed only for a specific power. For lamps of different powers, a dedicated heat sink must be additionally designed, so there are a large number of mold costs and inventory costs. Moreover, the conventional radiators are not equipped with structures that can be detached after being assembled, thus losing the mechanism of recycling and reuse, which needs to be overcome and solved.

One of the aims of the present invention is to provide a socket-type heat sink for a luminaire that can be adapted for use with a second heat sink in response to lamps of various powers.

In order to achieve the above object, the present invention provides a socket type heat sink for a lamp, comprising a heat conducting module, a first heat sink body and a second heat sink body, the heat conducting module comprising a heat conducting seat, a first a heat pipe, a second heat pipe and a pressure plate, wherein the first heat pipe and the second heat pipe are erected in a staggered manner on the heat conducting seat, and the pressure plate is pressed against the first heat pipe and the second heat pipe The first heat sink comprises a main cylinder and a plurality of cylinders disposed on the outer circumference of the main cylinder, and the two ends of the first heat pipe are respectively penetrated in the second cylinder; The second heat dissipating body is alternately sleeved on the heat conducting module and the first heat dissipating body, and the second heat dissipating body is provided with a receiving groove for respectively connecting the two ends of the second heat pipe.
