Abstract

The invention provides an LED (Light Emitting Diode) bubble lamp, which comprises a lampshade, a radiator and a lamp holder connected in sequence; an LED circuit board contacted with the upper end face of the radiator is arranged in the lampshade; an upper flow channel composed of a central tube is also arranged in the lampshade; a first through hole is arranged in the centre of the LED circuit board; a lower flow channel is arranged in the radiator; furthermore, a plurality of lower ventilation holes communicated with the lower flow channel are arranged on the outer wall of the radiator; the upper flow channel and the lower flow channel are communicated to form a heat dissipation channel; the cross section of the heat dissipation channel is gradually increased from the middle to the upper and lower ends. In the LED bubble lamp disclosed by the invention, the temperature of the radiator is effectively decreased through air circulating in the heat dissipation channel, so that heat in the LED bubble lamp is taken away; furthermore, the cross section of the heat dissipation channel is gradually increased from the middle to the upper and lower ends, namely, the middle of the heat dissipation channel is narrow; the openings at two ends are large, therefore, the circulation speed of air is effectively increased; in addition, the LED bubble lamp disclosed by the invention has good heat dissipation performances both in the erected use state and in the inversed use state.

Description

technical field [0001] The invention relates to a lighting device, in particular to an LED bubble lamp. Background technique [0002] Incandescent lamps are also known as tungsten filament lamps and light bulbs. They are electric light sources that heat the filament to an incandescent state and emit visible light through thermal radiation. It is widely used in home lighting occasions. However, incandescent lamps consume a lot of energy and have a short lifespan. With the rapid development of LED technology and the advantages of LEDs in terms of luminous principle, energy saving, and environmental protection, LED bubble lamps gradually replace incandescent lamps and become the best choice for new green lighting. choice. Since incandescent lamps still occupy a very high proportion in people's daily use, in order to reduce waste, the LED bubble lamp is designed to look similar to incandescent lamps, and the connection interface is suitable for traditional lamp bases and circui...
