HEAT DISSIPATION STRUCTURE FOR LED EXPLOSION-PROOF LAMP

摘要

A heat dissipation structure for an LED explosion-proof lamp includes an illumination module, a heat conduction disk, a window frame shell and a lamp set shell. The illumination module includes a base and at least one light-emitting diode. The heat conduction disk includes a plurality of installation holes. The window frame shell includes a light permeable portion, a window frame and a plurality of window frame connection holes. The lamp set shell includes a casing portion and a plurality of lamp set connection holes. Each compact member presses and holds the window frame shell and the lamp set shell. The heat conduction disk has a heat conduction zone formed on a projection location of the window frame shell and the lamp set shell, and a cooling zone encircled the heat conduction zone at an outer side to perform heat exchange with external air.

1. A heat dissipation structure for an LED explosion-proof lamp, comprising:
an illumination module including a base and at least one light-emitting diode located on the base; a heat conduction disk which is installed on the base and includes a plurality of installation holes along the circumference of the base; a window frame shell which is located at one side of the illumination module where the light-emitting diode is located and includes a light permeable portion corresponding to each light-emitting diode, a window frame encircled the light permeable portion and a plurality of window frame connection holes located on the window frame corresponding to the installation holes; a lamp set shell which is located at another side of the illumination module opposite to the window frame shell and includes a casing portion in contact with the heat conduction disk after assembly and a plurality of lamp set connection holes located on the casing portion corresponding to the window frame connection holes; and a plurality of compact members each run through one window frame connection hole, one installation hole and one lamp set connection hole that correspond to each other to press and hold the window frame shell and the lamp set shell at two opposite sides of the heat conduction disk; wherein the heat conduction disk has a heat conduction zone corresponding to a projection location of the window frame shell and the lamp set shell after has been coupled with the window frame shell and the lamp set shell, and a cooling zone encircled the heat conduction zone at an outer side and extended in a direction remote from the center of the heat conduction disk to perform heat exchange with external air.
