Description

A kind of LED bulb

Technical field

The utility model relates to light fixture, especially a kind of LED bulb.

Background technology

The common power consumption of conventional incandescent is big, and the temperature height, is unfavorable for energy-conservation.Along with the development of LED technology, it is found that LED is one of at present best lighting source, it has advantages such as luminosity height, long service life.But the temperature during the led light source operation is higher, for improving the running environment of led light source, all led light source can be installed on the radiator usually, utilizes radiator to distribute the operating heat of led light source.What existing LED bulb adopted usually is barrel-shaped radiator, and led light source is installed in the foam of barrel-shaped radiator end face, and the lamp holder that is connected with the led light source line is installed in the end face in addition of radiator.Barrel-shaped radiator has certain length usually, otherwise will not reach the heat radiation requirement in the led light source running.The LED bulb of this structure is because led light source and lamp holder are installed in the two ends of barrel-shaped radiator respectively, and therefore, the LED bulb lamp body of existing structure is long than common bulb usually, still can't accomplish identical with existing common bulb.When long LED bulb of this lamp body is installed on existing light fixture, be exposed to the outer bulb light of lampshade and directly shake human eye, can cause sense of discomfort, and outside the connecting portion of LED lamp holder and lamp socket is exposed to, seem not only inharmonious, but also not attractive in appearance to the people.

The utility model content

Technical problem to be solved in the utility model is to remedy the defective that prior art exists, and compact conformation, LED bulb that length is suitable with existing common bulb are provided.

The utility model is solved by the following method.

This LED bulb comprises: foam, radiator, led light source, the lamp holder that is connected with the led light source line.

The characteristics of this LED bulb are:

Described radiator is the barrel-shaped radiator of end sealing;

Described led light source is installed in the outer face of barrel-shaped radiator blind end;

The described lamp holder that is connected with the led light source line is installed in the inner face of barrel-shaped radiator blind end.

Technical problem of the present utility model is solved by following further technical scheme.

Described barrel-shaped radiator can be circular cylinder, square tube or polygon barrel-shaped radiator.

Described barrel-shaped radiator is made of end cap and cylindrical shell, and the outer face of end cap is provided with for the led light source installed platform.

Described barrel-shaped radiator end cap outer face is provided with the cannelure that embeds assembling for foam mouth end.

Described barrel-shaped radiator end cap is provided with louvre.

Described led light source is provided with light guiding lens.

The cylindrical shell of described barrel-shaped radiator is formed by the spaced fin system of enclosing.

Described barrel-shaped radiator is that thermal conductive metallic material is made.

Described barrel-shaped radiator is an aluminium matter barrel-shaped radiator.

Described led light source is the led light source paster, and it sticks on the outer face of barrel-shaped radiator blind end.

The design principle of the utility model LED bulb is: the lamp holder that is installed in the radiator outer end originally is installed in the barrel-shaped radiator, under the prerequisite that does not change radiator length and area of dissipation thereof, not only can shorten the bulb axial length effectively, realize and the isometric utility model purpose of common bulb, and do not influence the heat sinking function of barrel-shaped radiator at all.This structural improvement also can be hidden in the lamp holder that has no to decorate outside former being exposed in the barrel-shaped radiator, and the outward appearance of bulb is improved.When on lamp socket, installing, formed space between lamp holder in the barrel-shaped radiator and the barrel-shaped radiator inwall, just become lamp holder and screw the space that is connected cooperation with lamp socket, when revolving, puts after on the lamp socket by the LED bulb, the barrel-shaped radiator cover of LED bulb covers on outside the lamp socket, the connecting portion of lamp holder and lamp socket can be covered fully, be made LED bulb and lamp socket visually form one, reach decorative effect from outward appearance.

The beneficial effect that is compared with the prior art of the present utility model is:

This LED bulb structure compactness, is rationally being guaranteed on its energy-conservation, high light efficiency, the long-life basis, and its profile can be made into and to have common bulb now identical, can satisfy fully and has installing and using on the light fixtures such as various standard pendent lamps, Crystal lamp now.And, use safer because barrel-shaped radiator can be covered the connecting portion of lamp holder and lamp socket fully.

The concrete structure of LED bulb of the present utility model is provided in detail by the following drawings and embodiment.

Description of drawings

Fig. 1 is the schematic diagram of the utility model LED bulb embodiment 1;

Fig. 2 is the decomposition texture schematic diagram of LED bulb shown in Figure 1;

Fig. 3 is a LED bulb assembly structure schematic diagram shown in Figure 1;

Fig. 4 is the schematic diagram of the utility model LED bulb embodiment 2.

The specific embodiment

Embodiment 1: can be clear that from Fig. 1, Fig. 2, Fig. 3 the LED bulb is made up of foam 1, aluminium matter barrel-shaped radiator 2, led light source paster 3, light guiding lens 4 and lamp holder 5.

Described barrel-shaped radiator 2 is columnar structured, is made of aluminium matter end cap 21 and aluminium matter cylindrical shell 22, and the outer face of aluminium matter end cap 21 is provided with the platform of pasting for led light source paster 3 23.Be provided with the cannelure 24 that embeds assembling for 1 mouthful of end of foam around aluminium matter end cap 21 outer faces that led light source paster 3 is pasted the position, be furnished with the air-vent (not shown) on the aluminium matter end cap 21.
