Problems solved by technology

[0002] At present, LED is a kind of lighting lamp bead, which uses LED as a light source for indoor or outdoor lighting. LED bulbs generally operate with multiple lamp beads at the same time, which will cause the working temperature of LED and electronic drive components to rise rapidly. However, because the bulbs in the prior art lack an effective heat dissipation structure, LED bulbs that work continuously may cause LED flicker or even LED failure due to overheating.

no. 1 example

[0029] The first embodiment: as Figure 1 to Figure 3 As shown, an LED light bulb includes a metal connector 1, an insulating sleeve 2, a radiator 3 and a glass cover 4. The metal connector 4 is connected to the bottom end of the insulating sleeve 2, and an electronic component drive is installed in the insulating sleeve 2. The module 5, the radiator 3 is sleeved on the insulating sleeve 2, and the LED lamp board 6 is fixed on its top surface, and the characteristics are as follows;

[0030] The radiator 3 is a hollow spherical shape composed of an upper radiator 301 and a lower radiator 302 spliced ​​above and below. The outer wall of the insulating sleeve 2 near the bottom is provided with a supporting ring 201, which is sleeved on the insulating sleeve 2. The bottom surface of the lower radiator 302 is in contact with the supporting ring 201, and the top surface 301-1 of the upper radiator 301 is extended with a heat dissipation sleeve 301-2. The heat dissipation sleeve 301...

Abstract

The invention relates to a light emitting diode (LED) lamp bulb, which comprises a metal connector, an insulating sleeve, a radiator and a glass cover, wherein an LED lamp plate is fixed on the top surface of the radiator; the radiator is formed by vertically splicing an upper radiator and a lower radiator and has a hollow sphere shape; a radiating sleeve extends out of the top surface of the upper radiator and is sleeved and fixed on the insulating sleeve; a plurality of upper radiating holes communicated with an inner cavity are formed in the side wall of the upper radiator along the circumferential direction; and an upper central through hole and a lamp plate central through hole which are communicated with the upper radiating holes are respectively formed in the top surface of the radiating sleeve and the LED lamp plate. The LED lamp bulb is simple and rational in structure; the upper radiating holes, the upper central through hole and the lamp plate central through hole are communicated to form a rational gas flow channel, so that a radiating effect is effectively improved, and the service life of the lamp bulb is prolonged.

Description

technical field [0001] The invention relates to the technical field of light bulbs, in particular to an LED light bulb with good heat dissipation performance and large irradiation angle. Background technique [0002] At present, LED is a kind of lighting lamp bead, which uses LED as a light source for indoor or outdoor lighting. LED bulbs generally operate with multiple lamp beads at the same time, which will cause the working temperature of LED and electronic drive components to rise rapidly. However, because the bulbs in the prior art lack an effective heat dissipation structure, LED bulbs that work continuously may cause LED flicker or even LED failure due to overheating. [0003] In addition, in addition to placing the traditional lighting beads on the ceiling, the light source only needs to be irradiated in one direction from top to bottom, and many of them are also used to be placed on some lamps that require surrounding light sources (such as auxiliary lights next to ...
