Be applied to technique scheme, in described LED bulb lamp, the outer field outer surface of lamp housing also arranges at least three boss.

Be applied to each technique scheme, in described LED bulb lamp, lamp housing internal layer and lamp housing skin interconnect by the six heat dissipation metal muscle of evenly arranging, and plastic base also arranges and each heat dissipation ventilation lead to the hole site six fresh air inlets one to one.

Be applied to each technique scheme, in described LED bulb lamp, each heat dissipation metal muscle also arranges a metal bayonet socket with the end that is connected of lamp housing internal layer, and described face shield clamping is fixed on each metal bayonet socket.

Adopt such scheme, the utility model is mainly corresponding with the fresh air inlet that lamp holder arranges by the outer each heat dissipation ventilation through hole forming of lamp housing internal layer and lamp housing, make the some straight line convection channel of the inner formation of lamp housing, the inner hot-air forming of lamp housing, can overflow by the gap of top, the fresh air inlet of below enters cold air constantly, thereby cool cycles ventilation has improved radiating effect; And, be fixedly installed one for being adjacent to the heat conductive silica gel plane layer of fixed L ED light source module by the end face of lamp housing internal layer, the heat that LED light source module produces, can be by heat conductive silica gel plane layer guiding lamp housing internal layer, derive external environment condition by lamp housing internal layer and the outer heat radiation through hole forming of lamp housing again, accelerate radiating rate.

Accompanying drawing explanation

Fig. 1 is schematic diagram of the present utility model.

Fig. 2 is the structural representation of lamp housing in the utility model.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

The present embodiment provides a kind of LED bulb lamp, and described LED bulb lamp can form straight line convection channel, LED bulb lamp good heat dissipation effect, long service life by the radiator structure of setting and the air vent of lamp socket setting.

As depicted in figs. 1 and 2, LED bulb lamp comprises lamp housing 1, face shield 3, LED light source module 18 and lamp holder 2, wherein lamp housing is set to a radiator structure, radiator structure comprises integrated lamp housing internal layer 11 and lamp housing skin 12, lamp housing internal layer 11 is for being provided with the cylinder of cavity, lamp housing outer 12 is cone, and outer 12 outer surfaces of lamp housing can be set to the outer surface of arc.

Lamp housing internal layer 11 and lamp housing skin 12 interconnect by the heat dissipation metal muscle 13 arranging, and one-body molded.Wherein, at least three heat dissipation metal muscle can be set, preferably, six heat dissipation metal muscle can be set, the setting of evenly arranging of each radiating ribs; Between integrated lamp housing internal layer 11 and lamp housing skin 12, form some heat dissipation ventilation through holes 14, for example, six heat dissipation metal muscle are set, between lamp housing internal layer 11 and lamp housing skin 12, can form six heat dissipation ventilation through holes 14.

And, LED driver is fixedly installed in the cavity of lamp housing internal layer 11, the end face of lamp housing internal layer 11 is also fixedly installed a heat conductive silica gel plane layer 17, the bottom surface of LED light source module 18 is adjacent to and is fixed on heat conductive silica gel plane layer 17, in LED light source module 18, be provided with some Surface Mount LED19, so, the heat that LED light source module 18 produces, can pass through heat conductive silica gel plane layer guiding lamp housing internal layer 11, then the heat radiation through hole 14 forming by lamp housing internal layer 11 and lamp housing outer 12 is derived external environment condition.

Lamp housing skin 12 is connected with lamp holder 2 by a plastic base 4, plastic base 4 is also provided with some fresh air inlets 5, wherein, fresh air inlet 5 is corresponding one by one with the position of each heat dissipation ventilation through hole 14, and, fresh air inlet 5 is identical with each heat dissipation ventilation through hole 14 magnitude settings, so, each fresh air inlet forms a corresponding circulation road of the straight line being communicated with external environment condition with a heat dissipation ventilation through hole, the hot-air that between lamp housing outer 12 and lamp housing internal layer 11, gap forms, can overflow by the gap of top, 5 of the fresh air inlets of below enter cold air constantly, formation cool cycles is ventilated, effectively improve radiating effect.And, connect lamp housing and lamp holder by plastic base, in lamp housing when size, is set, lamp housing without with lamp holder size configure, lamp housing can arrange according to actual needs, radiating effect is better.

Face shield 3 is fixed on the top of lamp housing internal layer 11, and LED light source module 18 is placed in to its inside, particularly, can with the end that is connected of lamp housing internal layer, one metal bayonet socket 16 be also set at each heat dissipation metal muscle, face shield 3 is clamped respectively and is fixed on each metal bayonet socket 16, face shield 3 is transparent face mask, the light that each LED sends penetrates for illumination through face shield, so, can be that face shield user lamp housing skin exists gap, the hot-air that is lamp housing inside can overflow outside by gap, accelerates radiating rate.

Or the outer surface of lamp housing skin 12 also arranges at least three boss 15, as four boss 15 are evenly set, can expand the area of dissipation of the outer outer surface of lamp housing by the boss 15 arranging, radiating effect is better.

These are only preferred embodiment of the present utility model, be not limited to the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
