An LED lamp bulb disclosed by the utility model comprises a lamp socket arranged at the bottom of the lamp bulb, wherein an LED power circuit board is arranged in the lamp socket; a heat radiator is fixedly sleeved on the lamp socket; three LED lamp panels are fixedly arranged on the upper end face of the heat radiator; a semi-spherical lampshade is fixedly sleeved on the heat radiator; the upper end face of the heat radiator is a pyramid-shaped top end face consisting of three triangular inclined surfaces; and the three LED lamp panels are respectively and fixedly arranged on the three triangular inclined surfaces. The LED lamp bulb is applied to occasions to be lighted by LED light rays.

Description

A kind of LED bulb

Technical field

The utility model relates to the LED lighting, is specifically related to the LED bulb structure.

Background technology

Mention illumination, people can expect those motley various light fixtures in the lamp store at once.Although coming in every shape of these light fixtures, the core of its illumination--bulb mainly contain three kinds in fact: incandescent lamp and fluorescent lamp, gas-discharge lamp.But, this general layout will change soon because lighting field a nova--light emitting diode bulb is moving towards the practicability stage.

LED (Light Emitting Diode, light emitting diode) is a kind of solid-state semiconductor devices that can electric energy be converted into visible light, and it can directly be converted into light to electricity.Because the advantage of LED lighting engineering has been developed the novel light-emitting diode bulb that is used to throw light on recently.This bulb has efficient height, long characteristics of life-span, can use continuously 100,000 hours, than long 100 times of ordinary incandescent lamp bubble.In the coming years, this LED bulb becomes the main product of illumination of future generation probably.

Existing LED bulb is that profile is similar to incandescent light bulb, but its structure is different fully, generally is to adopt following structure: include the screw socket of light bulb base or the lamp socket of bayonet socket; Be arranged at the LED power supply circuit board in the lamp socket; Socket fixed heat sink on the lamp socket is placed a LED lamp plate on the radiator, the LED lamp plate generally adopts a plurality of LED that distribute on the circular substrate to form; The top that lies against radiator is then fixed; The fixing back of lampshade socket that the lampshade of the fixing dome-type of socket again on the radiator then, radiator generally are made into the latter half and the dome-type of globular bulb forms the profile of incandescent light bulb.

The weak point that existing this LED bulb structure exists is: it is not omnibearing that the light of LED distributes, and has certain illumination dark space.

The utility model content

The utility model technical problem to be solved is that overcoming existing LED bulb can't provide a kind of improved LED bulb structure than the deficiency of the even illumination in big orientation, can realize light illumination distribution more uniformly.

In order to solve the problems of the technologies described above, the utility model adopts following concrete technical scheme:

A kind of LED bulb comprises the light bulb base lamp socket is set, and is provided with the LED power supply circuit board in the lamp socket, and fixing radiator of socket on the lamp socket is placed on the radiator upper surface and is fixed with the LED lamp plate, the lampshade of the fixing dome-type of socket again on the radiator.Wherein, the top end of the triangle taper that the upper surface of described radiator is made up of three triangular ramps, the LED lamp plate is three, distributes respectively to place to be fixed on these three triangular ramps.

Further, the radiating fin of described radiator is to be on the outer wall that open wide to separate radial be arranged on the radiator cylindrical shell.

Further, a plurality of LED on the described LED lamp plate are distributed near the marginal position place.

The utility model adopts said structure, can realize that compared with prior art light illumination distributes more uniformly.LED lamp plate in the utility model LED bulb is three, distributes respectively and places the pyramidal top end that is fixed in radiator, can realize the more illumination of wide-angle; A plurality of LED on the LED lamp plate are distributed near the marginal position place simultaneously, thereby can prevent that like this intersection from insufficient light occurring and causing the dark space; Simultaneously, the radiating fin of radiator is to be on the outer wall that open wide to separate radial be arranged on the radiator cylindrical shell, so that partial L ED light can pass through downwards.Like this, the LED lamp plate of the utility model can increase by 135 ° to 180 ° endless belt luminous flux under the effect of glass lamp shade astigmatism, make it reach the requirement of Energy Star omnirange A type lamp.In addition, radiator can directly be produced through extrusion process, and the structure processing technology is simple.

The specific embodiment

Combine the accompanying drawing and the specific embodiment that the utility model is further specified at present.

Consult Fig. 1-shown in Figure 3; The LED bulb of the utility model includes: the light bulb base lamp socket is set; Lamp socket can be screw socket or bayonet socket; Lamp socket in the present embodiment adopts the screw socket structure, is made up of with 2 sockets of lamp socket adapter sleeve screw socket cover seat 1, and promptly screw socket cover seat 1 screws on the screwed pipe 21 that is socketed on lamp socket adapter sleeve 2 lower ends.Be provided with LED power supply circuit board 3 in the lamp socket, fixing radiator 4 of socket on the lamp socket, promptly the nozzle of radiator 4 lower ends is socketed on the urceolus 22 of lamp socket adapter sleeve 2 upper ends.The top end of the triangle taper that the upper surface of radiator 4 is made up of three triangular ramps 42; LED lamp plate 5 is three; Can be similarly triangle, 3 LED lamp plates 5 distribute respectively to place and are fixed on three triangular ramps 42 of radiator 4, can realize the more illumination of wide-angle like this.The lampshade 6 of the fixing dome-type of socket again on the radiator 4.Preferably, the radiating fin 41 of described radiator 4 is to be on the outer wall that open wide to separate radial be arranged on the radiator cylindrical shell, so that partial L ED light can pass through downwards.Preferably; LED lamp plate 5 is provided with screw socket; The triangular ramp 42 of radiator 4 is provided with screw 421 and wire through-hole 422; LED lamp plate 5 is fixed in screw 421 through screw closure, and the lead on the LED lamp plate 5 penetrates to the radiator cylindrical shell of radiator through wire through-hole 422, is connected on the LED power supply circuit board 3 again.Preferably, a plurality of LED51 on the described LED lamp plate 5 are distributed near the marginal position place, thereby can prevent that like this intersection from insufficient light occurring and causing the dark space.

Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
