【Technical field】

The utility model relates to a light-emitting diode (LED) lamp, in particular to a structural design of a light-emitting diode (LED) lamp which utilizes a fan to provide airflow and heat dissipation.

【Background technique】

Traditional lighting fixtures generally have two structures: incandescent bulbs and fluorescent lamps. Because the use of these light bulbs has a high power consumption situation, and heavy metals such as mercury in them will endanger the natural environment and human health, countries such as the European Union have legislated to restrict the use of these light bulbs containing heavy metals such as mercury. As a result, relevant industry players have developed LED lamps using high-power LEDs as light sources as a substitute for the aforementioned traditional lamps.

At present, the light-emitting diode lamp mainly installs a high-power light-emitting diode assembly in a lamp cup, and installs a lamp holder with a circuit board inside at the rear end of the lamp cup. The circuit board is connected with the high-power light-emitting diode. The components are electrically connected, and the circuit board is provided with a set of pins protruding from the rear end of the lamp holder, so that the light-emitting diode lamp can be plugged into the lamp holder through the pins, so that it can be controlled to provide lighting or decoration, etc. use.

In the aforementioned light-emitting diode lamps, high-power light-emitting diode elements are used to provide high brightness. Relatively, when the high-power light-emitting diode elements are lit, high temperatures will be generated. Therefore, how to overcome the high temperature generated by light-emitting diodes The problem is a subject for the related industry to work hard on.

The currently known improvement scheme is mainly to make the lamp cup made of thermally conductive material, and to form several heat dissipation fins on the outer peripheral surface of the lamp cup, so that the heat generated when the high-power light-emitting diode element is lit is guided to the lamp. On the cup, the lamp cup with several cooling fins is used to expand the heat dissipation surface area to assist in heat dissipation.

Although the above-mentioned known light-emitting diode lamp utilizes its lamp cup with several cooling fins to expand the heat-dissipating surface area to assist heat dissipation, it still cannot effectively dissipate the high temperature generated by the light-emitting diode light, and it is necessary to further improve it.

A hollow space is formed, and a fan is installed in the hollow space and electrically connected to the circuit board.

The beneficial effect of the utility model is that: by virtue of the structure design of the front exposed light-emitting diode lamp, its characteristics can not only make the heat generated when the high-power light-emitting diode assembly is lit, guide the heat dissipation lamp cup, but also pass through the heat dissipation lamp cup. The heat dissipation fins expand the heat dissipation area, and the airflow generated by the fan is used to blow to the heat dissipation lamp cup, so that the heat transferred to the heat dissipation lamp cup is quickly dissipated.
