Abstract

The utility model discloses an LED bulb, which comprises a base, a lamp socket and a plurality of LED light sources, wherein the lamp socket is arranged on the base; three mounting sides are arranged around the top of the lamp socket; and each mounting side is mounted with at least one LED light source. The LED bulb has a big illuminating angle so as to illuminate all around.

Description

A kind of LED bulb

Technical field

The utility model relates to lighting field, is meant the LED bulb that a kind of illumination range is wider especially.

Background technology

LED has plurality of advantages such as reaction speed is fast, reference color temperature is wide, luminous intensity is high, long service life, luminous efficiency height, good energy-conserving effect, be subjected to using widely in growing field, yet, LED is because light emission direction is stronger, therefore range of exposures is little, therefore if will replace traditional incandescent lamp, must solve the limited problem of its irradiating angle.Existing LED bulb is made up of led array, lamp socket and base, lamp socket is generally plate armature, led array promptly is arranged on this lamp socket, the LED bulb of this kind structure, its light emitting region is narrower, can not realize irradiation comprehensive, wide-angle, can't reach the requirement of lighting source, can't substitute common bulb and use, thereby limit its scope of application greatly.

Because above-mentioned analysis, the design people studies improvement at the existing defective of the structure of present LED bulb, and this case produces thus.

The utility model content

Main purpose of the present utility model is to provide a kind of LED bulb, and its irradiating angle is big, can realize omnibearing illumination.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of LED bulb comprises base, lamp socket and some led light sources, and lamp socket is installed on the base, and the top ring week of this lamp socket forms at least three installed surfaces, and at least one led light source all is installed on each installed surface.

The installed surface of above-mentioned lamp socket is the array installed surface of rule.

The outside of above-mentioned lamp socket also is arranged with a Transparent lamp shade.

The periphery of above-mentioned base is provided with some fin, and the inside of base forms the air channel that is communicated with lamp socket bottom and fin.

After adopting such scheme, the utility model is by being provided with the installed surface of at least three inclinations on the top of lamp socket, behind the installing led light source, can make that led light source shines towards different angles, but range of exposures is determined that by the angle of installed surface range of exposures increases greatly, thereby realizes the illumination of wide-angle, can replace bulb uses such as existing halogen tungsten lamp, enlarge the scope of application.

Description of drawings

Fig. 1 is a perspective view of the present utility model;

Fig. 2 is a front view of the present utility model;

Fig. 3 is the generalized section of Fig. 2.

The specific embodiment

Below in conjunction with drawings and the specific embodiments structure of the present utility model and beneficial effect are elaborated.

With reference to shown in Figure 1, the utility model provides a kind of LED bulb, comprises base 1, lamp socket 2 and some led light sources 3.

Base 1 is used for the LED bulb is fixed in socket, in the present embodiment, is to be formed with screw thread in the bottom, forms the relation of being spirally connected with socket.

Lamp socket 2 is fixed on the base 1, in the present embodiment, is the top of being fixed in base 1, and highly is higher than the height of base 1; At the installed surface (only being provided with three in the present embodiment) that also is formed with at least three inclinations the top of lamp socket 2 ring week, and in order to realize uniform illuminating effect, three installed surfaces are the array installed surface of rule.

The concrete quantity of led light source 3 can be determined according to environment for use and cost, it can be single LED, it also can be led array (as shown in this embodiment), be installed in respectively on each installed surface of lamp socket 2, thereby realize the illumination of different angles, and because the height of lamp socket 2 is higher than the height of base 1, the light that makes led light source 3 send can not blocked by lamp socket 2 or base 1, enlarge irradiating angle to greatest extent, improve brightness of illumination.

In addition, because the caloric value of LED is big, heat radiation is to use an important techniques problem of LED illumination, in the present embodiment, in order to reach better heat radiating effect, be that periphery at base 1 is placed with some fin 11, and the inside of base 1 forms the bottom of connection lamp socket 2 and the air channel 12 of fin 11, the heat that distributes when led light source 3 is worked like this is transmitted to the bottom by lamp socket 2, and mobile by air comparatively active in the air channel 12, effectively be dispersed into the external world by fin 11, and because fin 11 and the bigger contact area of external environment, improve radiating effect, prolong the service life of led light source 3.

Moreover, be not damaged in order to protect led light source 3, and improve aesthetic property, also can be at an outside sheathed Transparent lamp shade (not shown) of lamp socket 2.

In sum, a kind of LED bulb of the utility model, the tip designs that focuses on lamp socket 2 is the installed surface of a plurality of inclinations, like this after led light source is installed on each installed surface respectively, can realize omnibearing irradiating angle, enlarge illumination zone, making the LED bulb replace common bulb such as halogen tungsten lamp becomes possibility.

Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
