New Description: [New Technology Field] This creation relates to an LED lighting heat sink device, especially an LED light-emitting diode lighting heat sink suitable for indoor and outdoor lighting equipment. [Prior Art] At present, lighting equipment includes street lighting, advertising lighting, indoor lighting, and lighting of machinery and equipment. Among them, general street lights are connected to a hollow lamp housing at the bent end of the vertical pole. And with a translucent lampshade to provide night illumination of the road and surrounding environment. Generally, the illumination sources of indoor and outdoor and machine lighting equipment mostly use incandescent bulbs, neon bulbs, mercury lamps, etc. In addition to the environmental pollution caused by mercury vapor, the lighting efficiency is poor, the power consumption is relatively increased, and it is easy to damage and has a short service life. As a result, frequent repairs and replacements are required, which wastes manpower, material resources and time. Therefore, improvements are needed. The lighting source of the 5th to the inside and outside and the machine is known to have been replaced with a solid-state light-emitting diode to improve lighting efficiency and save electricity. However, the illumination source must have a plurality of light-emitting diodes arranged on the circuit substrate. As the light-emitting diodes are turned on and the output power is increased, in the electric light-thermal conversion process, the relative/BZL degree is relatively generated. In the heat, it is necessary to dissipate heat through the fins. However, all of the light-emitting body-high temperature heat can only be transmitted to the heat-dissipating fins through the insulating layer of the circuit board to dissipate heat, so that the heat-dissipating efficiency is poor and the heat-dissipating speed is slow, so that the temperature of the light-emitting diode is likely to be too high during long use. It seriously affects the lighting effect of the light-emitting diode, which in turn causes light decay and reduces the service life, so further improvement is necessary. 5 M311844 [New Content] The purpose of this creation is to provide _3| mouth-X· tOr m χ〇7 ΤΤΡΙ, one / kind of LED lighting heat sink, mainly for heat conduction
