Heat dissipating LED signal lamp source structure
First Claim
1. A heat dissipating LED signal lamp emitting structure, comprising:
- an isothermal board, made of a highly thermal conducting material;
a light emitting diode, attached on an upper side of the isothermal board;
a heat conducting cylinder, being a hollow body with an outer diameter not larger than that of the isothermal board, axially attached on a lower side of the isothermal board, having an electrode plug disposed on a lower distal surface thereof and electrically coupled to the light emitting unit;
a heat dissipating body, having a receiving hole for receiving the heat conducting cylinder;
a cover body, coupled to the upper side of the isothermal board, and having a reflecting groove for accommodating the light emitting unit; and
a lid, disposed on the cover body, for covering the light emitting unit inside the lid.

Abstract
A heat dissipating LED signal lamp emitting structure includes an isothermal board, a light emitting unit on the isothermal board, a heat conducting cylinder connected to the bottom of the isothermal board, a heat dissipating body around the periphery of the heat conducting cylinder and comprised of heat sinks, a circular cover body above the isothermal board for covering the isothermal board, a reflecting groove at the center of the cover body for passing through the light emitting unit, and a transparent lid on the cover body for covering the light emitting unit. With the heat dissipating effect of the heat dissipating body, the operating heat produced by the light emitting unit can be dissipated to the outside. The invention not only uses a single light emitting unit as a signal lamp emitting source, but also enhances the light emitting efficiency and the life expectancy of the light emitting unit.
