Description

The LED bulb

Technical field

The utility model relates to the bulb technologies field, and especially a kind of is the LED bulb of light source with LED.

Background technology

In daily life, the bulb that people use always mostly is incandescent lamp bulb and electricity-saving lamp greatly, but there is problem broken easily and that be difficult to reclaim in this bulb, and also there is the problem that power consumption is big and the life-span is short in this bulb with LED lamp ratio; Therefore people have been applied to the LED technology making field of bulb, as disclosed Chinese patent on February 28th, 2007, the patent No. be ZL200520144831.2's " a kind of LED bulb ", it is combined by lamp head and lamp socket portion, be provided with some circuit boards and some LED in the lamp socket, described lamp socket portion combines the projection direction of light that back rotatable described lamp socket portion adjusts LED in it with lamp head; This LED bulb is difficult at each angle projection light except that the lamp holder direction even, does not particularly almost have projection light at the top of lampshade, and this LED bulb sees that from appearance decorative effect is undesirable.

The utility model content

The technical problems to be solved in the utility model provides a kind of except that the bright dipping of cap part all directions is even, the LED bulb of good decorating effect.

For achieving the above object, the technical solution of the utility model is: a kind of LED bulb, comprise lamp holder, shell, transparent lamp shade, LED assembly, led drive circuit, lamp holder is connected the bottom of shell, the LED assembly is loaded on the top of shell, and transparent lamp shade is enclosed within on the LED assembly and is connected the top of shell, and the LED illuminator of LED assembly evenly is arranged on the outer surface and the upper surface of cylindricality circuit board, led drive circuit is arranged in the shell, and the power supply that lamp holder is introduced is connected with led drive circuit.

Above-mentioned LED bulb, described its outer surface of cylindricality circuit board forms cylindrical or hexagon, and the LED illuminator forms even distribution at its outer surface and upper surface.

Above-mentioned LED bulb, described transparent lamp shade can be designed to flame profile or cucurbit shape and can adopt the manufacturing of transparent Ya Keli material, further strengthen aesthetic.

Match with daily used lamp socket for convenience, described lamp holder can be made into screw socket type or bayonet type.

The utility model is because the LED illuminator is evenly distributed on the outer surface and the upper surface of cylindricality circuit board, its light projector direction is removed other all directions of cap part can both obtain light uniformly, and cap part and lamp socket match be in following or be in above, be not need throw light, its bright dipping and traditional incandescent lamp bulb and electricity-saving lamp are more approaching; On the other hand, because being evenly distributed on the outer surface and the upper surface of cylindricality circuit board, the LED illuminator adds shell attractive in appearance such as flame profile or cucurbit shape shell, the also optional majority sample of the color of LED illuminator, its good decorating effect.

Description of drawings

Fig. 1 is first kind of embodiment stereogram of the utility model;

Fig. 2 is second kind of embodiment stereogram of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.

Figure 1 shows that first kind of embodiment of the utility model: a kind of LED bulb, comprise lamp holder 1, shell 2, transparent lamp shade 3, LED assembly 4, led drive circuit 5, lamp holder 1 is connected the bottom of shell 2, LED assembly 4 is loaded on the top of shell 2, transparent lamp shade 3 is enclosed within on the LED assembly 4 and is connected the top of shell 2, the LED illuminator 41 of LED assembly 4 evenly is arranged on the outer surface and the upper surface of cylindricality circuit board 42, led drive circuit 5 is arranged in the shell 2, and the power supply that lamp holder 1 is introduced is connected with led drive circuit 5.

Cylindricality circuit board 42 outer surfaces form cylindrical, and LED illuminator 41 evenly distributes at its outer surface and upper surface; Cylindricality circuit board 42 outer surfaces also can form the shape that hexagon or octagonal etc. are suitable for 41 even distributions of LED illuminator and even light projector.

Transparent lamp shade 3 is for flame profile and can adopt the manufacturing of transparent Ya Keli material, the also available cucurbit shape of the shape of transparent lamp shade 3.

Lamp holder 1 makes things convenient for for the screw socket type and daily used lamp socket matches, and lamp holder 1 also can be designed to bayonet type.

Figure 2 shows that second kind of embodiment of the utility model: what they were different with first kind of embodiment is that lamp holder 1 ' is bayonet type, and lampshade 3 ' is the cucurbit shape; Obviously lamp holder 1 ' is replaceable be screw socket type or lampshade 3 ' replaceable be flame profile.

When being connected with lamp socket with the utility model first embodiment or second embodiment, connecting the power LED illuminator just can be luminous, the effect of playing illumination and decorating.

Also available other shapes of the shape of cylindricality circuit board external surface shape of the present utility model and lampshade, those skilled in the art is so long as the change that utilizes the design of this case to make unsubstantiality all falls into the protection domain of this case.
