Abstract

The invention relates to a light-emitting diode (LED) bulb lamp with a heat dissipation structure. The LED bulb lamp with the heat dissipation structure comprises a lamp cap, a lamp holder and a heat dissipation body, wherein the lamp cap is provided with the lamp holder, and the lamp holder is provided with the heat dissipation body. A driving power source is arranged inside the lamp holder, and a plurality of grooves are evenly distributed in the heat dissipation body. An LED light source assembly is arranged inside each groove, and a lamp shade is arranged outside each LED light source assembly. The lamp shades are fixed inside the grooves. The bottom end of the lamp holder and the top of the heat dissipation body are respectively and evenly provided with a plurality of air vents, and the air vents in the lamp holder corresponding to the heat dissipation body are located in the same center line. The LED bulb lamp with the heat dissipation structure has the advantages that due to the facts that except three luminous circular windows, all superficial areas of the appearance of the heat dissipation body contact air directly and the air vents which penetrate through each other in an up-down mode are arranged inside the heat dissipation body, convection of cold and hot air is formed, and heat conduction and heat dissipation are particularly effective. Hollow and circular luminous windows are adopted and are not only the heat dissipation body but also carriers of the LED light source assembly. A whole lamp body appearance is complete, and the structure is unique.

Description

technical field [0001] The invention relates to an LED bulb lamp with a heat dissipation structure. Background technique [0002] At present, if the light source board of the LED bulb is installed on the heat dissipation body, the luminous range cannot meet the requirements of the full-circumference light. Large, the heat dissipation effect is greatly reduced. It is not conducive to the reduction of the junction temperature of the LED. There is also a design, the upper part is also a heat sink, but most of the surface area is covered by a reflector and a light-transmitting cover, and the heat dissipation is not ideal. Contents of the invention [0003] The object of the present invention is to provide a LED bulb lamp with a heat dissipation structure, which greatly increases the contact area between the outer surface of the heat sink and the air, so that the heat generated by the LED light source can be efficiently conducted and dissipated, and the structure is simple. ...
