Description

  The present invention relates to a lighting device, and more particularly to a light bulb type light emitting diode illuminator and a heat dissipation structure thereof.

A general tungsten light bulb has a feature that tungsten is used as a light source, its structure is simple, and installation and replacement are very convenient.
Normally, the structure of a tungsten bulb is connected by fixing an adapter to the end of a spherical lampshade.
The adapter has a screw thread and can be screwed into a general light bulb. When energized, tungsten installed in the lamp shade generates heat and emits light, and light rays are irradiated to the outside through the lamp shade, thereby achieving the purpose of use as illumination.

  However, when a tungsten bulb emits illumination light, it emits a large amount of thermal energy at the same time. Therefore, power consumption is very high, energy is wasted, and tungsten is burned out easily, so that the service life of tungsten bulbs is short.

A light emitting diode (LED) is a solid state light source that converts electrical energy into light energy.
The light emitting diode has characteristics such as a small volume, a low driving voltage, a fast reaction speed, strong vibration, and a long life. With the development and progress of technology, there is an increasing demand for compact electronic components.
For this reason, the bulb-type light-emitting diode illuminator is gradually replacing the tungsten bulb, and is applied in large quantities and widely.

Conventional light-emitting diode illuminators mainly include a circuit board, a plurality of light-emitting diodes electrically connected to the circuit board, a light-transmitting cover that covers the light-emitting diodes, and an aluminum extrusion that bonds and connects the circuit boards. It consists of a mold heat spreader and an adapter fixed to the aluminum extrusion heat spreader.
However, the heat dissipation efficiency of the aluminum extrusion type heat sink is determined by its surface area, and the surrounding gas exchanges heat only with the surface of the aluminum extrusion type heat sink.
Therefore, there is a limit to the heat dissipation effect, and the heat dissipation rate is slowed, which affects the operating performance of the bulb-type light-emitting diode illuminator.
The present invention has been made in view of the above-described drawbacks of the heat-dissipating structure of a conventional light-emitting diode illuminator.
