New description: [New technical field] A heat dissipation technology, especially a heat sink for lamps. [Prior Art] In recent years, the cost of application has been rising, and related energy-saving products have emerged. 1 Φ Miscellaneous soil, medium, and light-emitting diodes (LED) are energy-saving, environmentally friendly, long-life, and multi-colored. And so on, and widely used in the field of display and lighting. For example, a luminaire using a light-emitting diode as a light-emitting element can use a high-luminance light-emitting diode, but since the light source generated by the light-emitting diode is a "dot" light source, when a light-emitting diode is applied to a light-emitting device, Usually, a plurality of light-emitting diodes are provided as the light-emitting elements 7L to generate a "face" light source similar to a conventional fluorescent tube or a bulb, while increasing the luminous power to produce the same brightness as the fluorescent tube or the bulb. Performance. At the same time, the light-emitting diode lamps used in the Chang'an Temple, ', and Ming's are generally constructed with a heat dissipation mechanism. The purpose is to prevent problems such as light decay or damage of related components due to overheating of the wafer. ', and the general use of the light-emitting diodes used in the heat dissipation mechanism, mainly using the metal shell directly, or the fins on the metal shell to achieve the purpose of heat dissipation, it has the following disadvantages: 1 The use of natural air convection to dissipate heat is easy to affect the heat dissipation efficiency of the lamp due to changes in surrounding environmental conditions. 3 M359644 2·The lamp housing is easily covered by dust, which reduces the original heat dissipation. : Improve the heat release efficiency; see the technical system to set up the fan: 忒: in the 'provide - the power supply through the light-emitting components and the other source of the package through the fan, that is, the power supply mode of the dual power supply'冀The fan is caused to generate an air flow to remove the heat generated by each of the light-emitting elements. As a result, if the fan in the prior art fails or fails, the heat dissipation effect is lost; thus, when the lamp is continuously used and the heat dissipation mechanism cannot be surely activated, each of the light-emitting elements is easily damaged by overheating. It can be seen from the above that how to propose a heat dissipation technology to solve the various shortcomings of the prior art described above is an urgent problem to be solved. [New content] In view of the various shortcomings of the prior art, one of the aims of the present invention is to provide a heat sink for a lamp that can surely activate the heat dissipation mechanism. ... Another object of this creation is to provide a heat sink for lamps that can improve heat dissipation efficiency. A further object of the present invention is to provide an optical, non-shaded, luminaire heat sink. In order to achieve the purpose and other purposes, the creation of "lighting device for heat dissipation" is applied to dissipate 4 M359644 heat to a plurality of light-emitting elements in the lamp, and the lamp provides a constant current power source through each of the light-emitting elements 'including · a substrate for carrying each of the light-emitting elements; an annular heat-dissipating block disposed on a surface of the substrate, having a heat-dissipating channel disposed opposite to each other, a plurality of heat-dissipating fins respectively protruding from the outer peripheral edge and the inner peripheral edge, and two portions A plurality of mounting holes of the adjacent heat-dissipating fins and a fan share the constant current power supply with the light-emitting elements and are mounted on the annular heat sink for generating a heat-dissipating airflow. In the "lamp heat sink" described above, the substrate includes a plurality of air holes provided corresponding to the periphery of each of the light-emitting elements. The substrate is one of a metal circuit board and a south heat-dissipating heat-dissipating substrate. Each of the heat dissipating fins is radially disposed on a periphery and an inner periphery of the annular heat sink. The plurality of assembly holes includes a plurality of c-shaped mounting holes and a plurality of U-shaped mounting holes. The c-shaped mounting holes are located between adjacent ones of the inner fins of the annular heat sink, wherein the positions of the C-shaped mounting holes correspond to the fan. The U-shaped mounting hole is located between adjacent heat-dissipating fins on the outer circumference of the annular heat-dissipating seat, wherein the Y-shaped mounting hole is disposed at a position corresponding to the substrate. In the embodiment, the plurality of C-shaped mounting holes and the plurality of U-shaped mounting holes are spaced apart. / The objective of the present invention is that the fan of the present invention and each of the illuminating elements are powered by a constant current source, and when the fan is damaged or fails, it cannot be supplied to each of the illuminating elements. In this way, one side: to prevent each of the light-emitting elements from being damaged by overheating, and on the other hand, to remind the user to replace or repair the fan in time. At the same time, the application of 5 M359644 is a day-to-day application, since the substrate includes a plurality of air holes corresponding to the periphery of each of the light-emitting elements, so that the airflow generated by the fan can directly blow away or absorb the heat generated by each of the light-emitting elements, and relatively increase The heat dissipation area '俾 improves heat dissipation efficiency.曰 '........« η, inter
