Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a heat sink and a light-emitting diode lamp using the same. [Prior Art] [0002] As a new generation of light source, the light-emitting diode light source can not replace the traditional incandescent lamp on a large scale, but it has the advantages of long working life, energy saving and environmental protection, and is generally marketed. I am optimistic. At present, the module composed of the light-emitting diode can generate a high-power, high-brightness light source, so the stomach will widely and revolutionarily replace the conventional light source such as the traditional incandescent lamp, and become the main light source that meets the theme of energy conservation and environmental protection. [0003] However, the greater the power and brightness, the greater the heat generated by the LED or its module, and it is difficult to dissipate in a relatively small volume of the LED package. Therefore, the LED has a large heat dissipation technology bottleneck, which is the key to the breakthrough of the current market for high-power, high-brightness LED lamps. At present, the heat dissipation scheme commonly used in the industry is to provide a heat sink in the luminaire, and to radiate heat into the surrounding air through the surface of the heat sink in contact with natural convection air. Therefore, to meet high power, high brightness

The inner circulation air flow path can effectively enhance the airflow and increase the area of the first heat sink 20 in contact with the air flow, thereby well solving the heat dissipation problem of the high power light emitting diode module 30. [0016] Since the LED module 30 is limited by a certain illumination angle, the emitted light is mostly distributed within a range of 30° along the perpendicular of the LED module 30. In this embodiment, the top end portion of the outer plate 43 of the body 40 of the second heat sink protrudes outward, so that the light-emitting diode module 30 attached to the outer plate 43 and the 096143438 form number A0101 page 9 / A total of 18 pages 0993217435-0 1331200 June 22, 099 nuclear replacement page a heat sink 20 has a certain angle of extension of the longitudinal direction, so that the illumination angle of the LED module 30 can be compared with the vertical setting It is yawed below the horizontal line to increase the downward illumination area to meet the user's lighting needs at that angle. [0017] FIG. 4 shows a second embodiment of a light-emitting diode lamp of the present invention. The light-emitting diode lamp of the present embodiment also includes a lamp holder 10, a first heat sink 20 connected to the lamp holder 10, and is attached to the first embodiment. The second heat sink on the periphery of the heat sink 20 and the plurality of light emitting diode modules 30 attached to each of the bodies 40a of the second heat sink. The structure of the components is the same as that of the corresponding component of the LED lamp of the previous embodiment. However, the body 40a of the embodiment is formed by inverting the body 40 of the previous embodiment, that is, The height of the body 40a gradually decreases from bottom to top. The body 40a thus disposed can illuminate the illumination angle of the LED module 30 above the horizontal line, so that the upward illumination area is increased to meet the illumination needs of the user at the angle. [0018] In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and equivalent modifications or variations made by those skilled in the art of the present invention should be included in the following claims.
