Description

The LED bulb lamp

Technical field

The utility model relates to LED lighting technical field, particularly a kind of LED bulb lamp.

Background technology

Along with the continuous aggravation of global energy shortage and environmental pollution, energy-conservation and environmental protection has become the imperative problem that needs solution of current society.In recent years, the illuminating LED lamp is at cost, and aspect of performance has had very big improvement, compare with conventional light source, it is long that the LED lighting has the life-span, preferably drive characteristic, start-up time is short, and advantage such as sound construction, has great importance for environment and energy savings.Yet at present the LED bulb lamp of exploitation area of dissipation and radiator structure in the design of integral body is unreasonable, causes bulb overheated and decay is serious, and its life-span is reduced.In addition, have certain problem owing to go out light effect in design, particularly there is low light transmission in some great power LED bulb lamps, and luminous point is arranged, and the unequal shortcoming of mixed light causes the whole light efficiency of LED lamp not good.

The utility model content

The technical problems to be solved in the utility model is: the LED bulb lamp that a kind of simple in structure, good heat dissipation effect, light extraction efficiency height, free from glare are provided.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED bulb lamp, comprise lamp holder, the lamp holder connector, driving power, aluminum hull heat radiation lamp body, hemispheric PC expands the light modulation cover, aluminium base with become array distribution and be welded on led light source on the aluminium base, lamp holder is fixedlyed connected with the lower end of aluminum hull heat radiation lamp body by the lamp holder connector, driving power is installed in lower end in the aluminum hull heat radiation lamp body, PC expands light modulation cover spiral-lock on the aluminium base of led light source and be fixed on the upper end of aluminum hull heat radiation lamp body, in the aluminum hull heat radiation lamp body heat conducting base that is positioned at the aluminium base below is installed, heat conducting base one end is fixedlyed connected with aluminium base, and the other end is fixedlyed connected with driving power.

Junction with aluminum hull heat radiation lamp body on the PC expansion light shield has screw thread, and the upper end inwall of aluminum hull heat radiation lamp body has thread groove, and the screw thread that thread groove and PC expand on the light modulation cover matches.

The junction that lamp holder connector, heat conducting base and PC expand light modulation cover and aluminum hull heat radiation lamp body inwall all scribbles high thermal conductive silicon fat layer.

PC expands light transmittance 〉=93% of light modulation cover.

The beneficial effects of the utility model are: be provided with a heat conducting base between led light source and aluminum hull heat radiation lamp body, and the junction all scribbles high thermal conductive silicon fat layer, radiating effect is good especially, great power LED is fixed on the aluminium base, the heat of led light source inside can be derived as early as possible, reducing the junction temperature of LED wafer, thereby improve the luminous efficiency of LED lamp, and then prolonged the life-span of LED lamp; Employed hemispherical expands the light modulation cover, and its light transmission efficiency is up to more than 93%, and the LED point light source light-emitting can be converted to the luminous effect of sphere, has effectively solved dazzle, and the shadow phenomenon has increased the soften of light.

Description of drawings

Fig. 1 is an explosive view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described further.

As shown in Figure 1, a kind of LED bulb lamp, comprise lamp holder 1, lamp holder connector 2, driving power 3, aluminum hull heat radiation lamp body 4, hemispheric PC expands light modulation cover 5, aluminium base 6 with become array distribution and be welded on led light source 7 on the aluminium base 6, lamp holder 1 inwall is provided with spiral helicine screw thread and lamp holder connector 2 matches fixing, the lower end of aluminum hull heat radiation lamp body 4 is connected and fixed with the afterbody of screw and lamp holder connector 2, driving power 3 is built in by three plastic barrier parts to be formed in the cylinder of specific dimensions, and lower end in the aluminum hull heat radiation lamp body 4 of packing into, junction with aluminum hull heat radiation lamp body 4 on the PC expansion light shield 5 has screw thread, the upper end inwall of aluminum hull heat radiation lamp body 4 has thread groove, the screw thread that thread groove and PC expand on the light modulation cover 5 matches, PC expands light modulation cover 5 spiral-locks on the aluminium base 6 of led light source 7, and detain on the thread groove of aluminum hull heat radiation lamp body, in the aluminum hull heat radiation lamp body 4 heat conducting base 8 that is positioned at aluminium base 6 belows is installed, heat conducting base 8 one ends and aluminium base 6 are fixedlyed connected by screw, and the other end is screwed with driving power 3 and is connected.
