Abstract

A fastening type heat-dissipation structure for connecting a light-emitting module to an enclosure includes a first fixing member and a second fixing member separately attached to two opposite inner sides of the enclosure; and a flat plate, on which the light-emitting module is mounted. The flat plate is provided with at least a first extended section and at least a second extended section for abutting on and locking to the first and the second fixing member, respectively, so that the flat plate is firmly mounted in the enclosure via the fixing members. And, heat produced by the light-emitting module mounted on the flat plate can be transferred via the extended sections and the fixing members to the enclosure and dissipated from the enclosure into ambient air to enable largely upgraded heat-dissipation effect.

Description

    FIELD OF THE INVENTION
  • The present invention relates to a fastening type heat-dissipation structure, and more particularly to a fastening type heat-dissipation structure that not only connects an LED module to a lamp shell, but also transfers heat produced by the LED module to the lamp shell for dissipating into ambient air.
    • BACKGROUND OF THE INVENTION
  • For the current street lamps to meet the requirements and targets of environmental protection, energy saving, and carbon reduction, conventional light emitting elements for the street lamps, such as halogen lamps and incandescent bulbs, have been gradually replaced by light-emitting diodes (LED) lamps.
  • LED has been widely applied in many different fields since it was developed in 1955.
  • The working principle of an LED lamp is to convert electric energy into light energy. To manufacture an LED, first, group V elements, such as N, P, As and the like, and group III elements, such as Al, Ga, In and the like, are subjected to, for example, liquid phase epitaxy (LPE) or vapor phase epitaxy (VPE) to produce a group III-V compound semiconductor, such as GaP or GaAs, for use as a substrate. Then, a voltage is applied to an anode and a cathode of the substrate. When electric current flows through the substrate, electrons and holes combine with one another. At this point, the electrons fall into a lower energy level and accordingly, release surplus energy in the form of photons, that is, to emit light.
  • However, it is not easy to substitute LED street lamps for all the conventional street lamps using halogen lamps and incandescent bulbs. This is because the lamp holders and the mounting structures for the conventional halogen lamps and incandescent bulbs are quite different from those for the LED lamps, and it is impossible to directly replace the halogen lamps and incandescent bulbs with the LED lamps just in a very simple manner. It requires high cost and is therefore not economical if a whole street lamp is discarded in order to use the LED lamp.
  • On the other hand, while the LED has the advantages of low power consumption and increased brightness, it would produce more heat than the halogen lamp and incandescent bulb and therefore requires additional heat-dissipating device to remove the produced heat. Since the conventional halogen lamp and incandescent bulb produce less heat and basically does not require heat dissipation, the halogen and incandescent street lamps are not provided with any heat-dissipation design. Therefore, some major parts, such as the lamp shell, of the conventional halogen lamp and incandescent bulb could not be directly used with the LED lamp that produces high amount of heat and requires heat dissipation. To redesign these major parts, including the lamp shell, for the LED street lamp, molds must be made and new codes for use safety and tests must be re-established. All these require high investment cost and long developing time.
  • In brief, the conventional way of substituting LED lamp for halogen lamp and incandescent bulb used in street lamps has the following disadvantages: (1) requiring high cost; (2) requiring long developing time; and (3) requiring differently designed parts, such as lamp shell.
    • SUMMARY OF THE INVENTION
  • A primary object of the present invention is to provide a fastening type heat-dissipation structure, with which an incandescent bulb in the conventional street lamps can be directly replaced with an LED lamp simply by mounting the LED lamp on the heat-dissipation structure and then fastening the latter on the existing lamp shell.
  • Another object of the present invention is to provide a fastening type heat-dissipation structure that is able to transfer heat produced by a lamp to a lamp shell for dissipating into ambient air, so as to enable upgraded heat dissipation performance.
  • To achieve the above and other objects, the fastening type heat-dissipation structure according to a preferred embodiment of the present invention is designed to connect a light-emitting module to an enclosure, and includes a first fixing member, a second fixing member, and a flat plate. The first fixing member has a first fixing section for internally bearing against one side of the enclosure; the second fixing member has a second fixing section for internally bearing against another side of the enclosure opposite to the first fixing member; and the flat plate has at least a first extended section and at least a second extended section. The first extended section has a first mounting end for correspondingly abutting on the first fixing member, and the second extended section has a second mounting end for correspondingly abutting on the second fixing member. And, the light-emitting module is fixedly mounted on a top surface of the flat plate.
  • With the specially designed fastening type heat-dissipation structure of the present invention, an incandescent bulb for the conventional street lamp or other types of lamps can be directly replaced with an LED lamp simply by mounting the LED lamp on the fastening type heat-dissipation structure of the present invention and then fastening the latter to an existing lamp shell. In this manner, it is not necessary to discard the whole lamp shell when the lamp holder structure is changed. Further, the heat produced by the LED lamp can be transferred via the heat-dissipation structure to the lamp shell for dissipating into ambient air. Thus, the present invention advantageously enables reduced lamp cost, enhanced heat dissipation effect, and prolonged lamp service life.
