Description

LEDbulb lamp

Technical field

The utility model relates to field of LED illumination, particularly a kind of LEDbulb lamp.

Background technology

Existing LED lamp application is more and more extensive, and operationally, can give out a large amount of heats, power is larger for LED light source, and the heat distributed is more, considers the hyperthermia and superheating phenomenon produced when LED light source works, needs the object reaching auxiliary heat dissipation in conjunction with radiator.At present, LEDbulb lamp is typically equipped with radiator auxiliary heat dissipation, but existing radiator heat-dissipation process air mobile phase is to less, and radiating effect meets the requirements not yet.In addition, the light source board of LEDbulb lamp is as being arranged in heat radiator body, then luminous scope does not reach the requirement of all-round light, if and light source board raises installation, luminous scope increases, and the distance of light source board and heat radiator body strengthens, and radiating effect reduces greatly, be unfavorable for the reduction of LED light source junction temperature, very easily cause LED light source to lose efficacy or affect the use safety of light fixture.

Utility model content

In view of this, the LEDbulb lamp providing a kind of radiating efficiency high is necessary.

The technical solution adopted in the utility model is: a kind of LEDbulb lamp, comprise bulb housing, light source board, radiating piece, first LED light source, this bulb housing is the ball bubble shell structure of bottom opening, this light source board is arranged on the inside of this bulb housing, this the first LED light source is arranged on the front of this light source board, this radiating piece is the hollow tubular structure of two ends perforate, the bottom of this bulb housing is provided with fixed structure and through hole, the bottom of this radiating piece is fixed on the fixed structure of this bulb housing, this light source board is arranged on the top of this radiating piece and thermally coupled with this radiating piece, this light source board is provided with air vent, this air vent, this radiating piece and this through hole are interconnected formation air convection channel.

Compared with prior art, this air vent of this LEDbulb lamp, this radiating piece and this through hole are interconnected formation air convection channel, the heat that LED light source produces can be dispersed into space outerpace timely by heat loss through convection passage, effectively take away the heat that this light source board produces, thus greatly reduce the temperature of LED light source, improve the radiating efficiency of the whole lamp of this LEDbulb lamp, extend the service life of this LEDbulb lamp.

Detailed description of the invention

Fig. 1 is the three-dimensional exploded view of the LEDbulb lamp of the utility model first embodiment, this LEDbulb lamp comprises bulb housing 10, light source board 20, radiating piece 30, first LED light source 40, this bulb housing 10 is the ball bubble shell structure of bottom opening, this light source board 20 is arranged on the inside of this bulb housing 10, this the first LED light source 40 is arranged on the front of this light source board 20, also comprise the second LED light source 50, this second LED light source 50 is arranged on the back side of this light source board 20.

In the present embodiment, this light source board 20 is positioned at the middle part of this bulb housing 10, and this light source board 20 is arranged on the top of this radiating piece 30 and thermally coupled with this radiating piece 30.Wherein, this first LED light source 40 and this second LED light source 50 comprise plurality of LEDs light source respectively, this first LED light source 40 and this second LED light source 50 are arranged around this radiating piece 30 respectively, and like this, these LED light sources just can illuminate the top of this bulb housing 10, sidewall and bottom and realize all-round luminescence.In addition, the outer surface of this radiating piece 30 also can apply the light that reflector layer sends to reflect these LED light sources towards this bulb housing 10.

Please refer to Fig. 1 to Fig. 3, the bottom of this bulb housing 10 is provided with fixed structure 11 and through hole 12, the top of this bulb housing 10 is provided with perforation 13 and guide duct 14, and one end of this guide duct 14 is communicated with the top of this radiating piece 30, and the other end of this guide duct 14 is communicated with this perforation 13.This bulb housing 10 is made up of transparent or semitransparent insulating materials.This bulb housing 10 was hemisphere bubble shell structure, and this bulb housing 10 is assembled by upper and lower two housings, by ultrasonic bond or the connection that is fastened.

Please refer to Fig. 1 to Fig. 3, this radiating piece 30 is the hollow tubular structure of two ends perforate, and make air to pass this radiating piece 30, the bottom of this radiating piece 30 is fixed on the fixed structure 11 of this bulb housing 10.The bottom of this radiating piece 30 is pressed on this fixed structure 11, and this guide duct 14 is pressed on the top of this radiating piece 30 thus is gripped by this radiating piece 30, and in the present embodiment, this guide duct 14 also can be pressed on this light source board 20.This light source board 20 is provided with air vent 21, and this air vent 21, this radiating piece 30 and this through hole 12 are interconnected formation air convection channel.
