The utility model content:

Technical problem to be solved in the utility model is exactly in order to overcome the deficiency that present LED bulb exists, propose a kind of can realize simultaneously end face luminous, 360 the degree lateral emittings, realize solving quickly and efficiently the heat that led chip produces, thereby reduce the led chip operating temperature, slow down the led chip aging speed, improve the LED bulb in its service life.

For solving the problems of the technologies described above, the utility model has adopted following technical scheme: this LED bulb comprises lamp adapter assembly, heat conduction main body, drive circuit board and is encapsulated in led light source on the heat conduction main body by diffuser, described heat conduction main body has an erecting bed, and erecting bed around and end face be distributed with described led light source.

Described heat conduction main body periphery is with a radiator, wherein, forms several cross-ventilation grooves, several fin on the radiator.

Described erecting bed comprises: boss, be positioned at the cylinder at boss center, wherein form center height, low awl inclined-plane all around on the cylinder, be distributed with described led light source in the end face and the awl inclined-plane of cylinder.

Described led light source comprises: circuit board and be positioned at led chip on the circuit board, described circuit board is fixed on the end face and awl inclined-plane of described cylinder.

Described lamp adapter assembly comprises: the plastic cement shell, be installed on the lamp holder on the plastic cement shell.

Described drive circuit board comprises: power panel, control plate.

The utility model has the following advantages after adopting said structure:

1, on a heat conduction main body, a plurality of led light sources has been installed, and these light sources are level 360 degree, end face distributes simultaneously, can realize omnibearing luminous, can realize simultaneously end face luminous, 360 the degree lateral emittings, overcome the too small shortcoming of present LED bulb irradiation scope.

2, be with a radiator in heat conduction main body periphery, can realize solving quickly and efficiently the heat that led chip produces by radiator, thereby reduce the led chip operating temperature, slow down the led chip aging speed, improve its service life.

3, can in the voltage of 0～260V, use, can use in the whole world.

4, can cooperate light modulator to carry out light modulation, can be widely used in the light fixtures such as lamp affixed to the ceiling, pendent lamp, desk lamp.
