Description

A kind of LED bulb

Technical field

The utility model relates to a kind of bulb, particularly a kind of LED bulb for daily room lighting.

Background technology

At present, the light emitting source that indoor illumination adopts is take incandescent light bulb or fluorescent tube as main basically, yet, the electro-optical efficiency of incandescent light bulb and fluorescent lamp tube is all lower, and its caloric value is large, and service life is short, generally only has about 3000 hours.

LED is as a kind of novel light emitting semiconductor device, and it has the series of advantages such as volume is little, caloric value is low, power consumption is low, electro-optical efficiency is high, the life-span is long, many light fixtures take LED as light source therefore occurred in the market.But these LED light fixtures all only are the peripheral directly sheathed lampshade composition LED bulb light emitting sources at led light source at present, this has affected the light extraction efficiency of LED, and its radiating effect is bad, shortened greatly the service life of light fixture, its profile is also attractive in appearance not, decorative effect is poor, affects using and selecting of consumer.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of have good light extraction efficiency, good heat dissipation effect and simple and reasonable LED bulb.

The utility model solves the employed technical scheme of its technical problem:

A kind of LED bulb, it comprises lamp holder, on the described lamp holder lamp socket is installed, lamp socket is a pyramidal structure, the sidepiece of described lamp socket is provided with radiating fin, and the driving power that is electrically connected with lamp holder is installed in the lamp socket, the top of described lamp socket be equipped with can be reflective the LED lamp plate, be provided with led light source on the LED lamp plate, led light source is electrically connected with driving power in the lamp socket; Also be arranged with transparent lamp shade on the described lamp socket, LED lamp plate and led light source are positioned at transparent lamp shade inside.

As improvement of the technical scheme, described transparent lamp shade is the semielliptical shape.

As further improvement in the technical proposal, the length of described transparent lamp shade is the twice of its bottom surface diameter.

Preferably, be provided with the heat radiation aperture on the sidewall of described lamp socket.

Further, described lamp socket is a pyramidal structure, and the pyramidal structure of radiating fin and lamp socket is suitable.

Further, be respectively arranged with corresponding screw on described lamp socket and the LED lamp plate, the LED lamp plate is fixedly mounted on the lamp socket by screw.

The beneficial effects of the utility model are: the utility model arranges radiating fin by the sidepiece at lamp socket, the top of lamp socket be equipped with can be reflective the LED lamp plate, so that the light that led light source sends its light extraction efficiency after the LED lamp plate is reflective improves greatly, the setting of radiating fin then so that the heat that led light source sends can be discharged from timely in the transparent lamp shade, improve greatly the heat dispersion of LED bulb, effectively prolonged the service life of LED bulb.The simple and reasonable compactness of the utility model, easy for installation, light extraction efficiency is high, perfect heat-dissipating.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is decomposing schematic representation of the present utility model.

The specific embodiment

With reference to Fig. 1 ~ Fig. 2, a kind of LED bulb of the present utility model, it comprises lamp holder 1, on the described lamp holder 1 lamp socket 2 is installed, the lower end of lamp socket 2 is fixed by being coated with glue bond after being inserted in the lamp holder 1, the sidepiece of described lamp socket 2 is provided with radiating fin 21, lamp socket 2 adopts the aluminium material manufacturing, also can use copper material, the material manufacturings such as kirsite, the heat that led light source 4 produces that is arranged so that of radiating fin 21 can be taken out of transparent lamp shade 5 timely, guarantee that transparent lamp shade 5 interior temperature can be too not high, so that led light source 4 is worked all the time, prolonged the service life of led light source 4 and whole LED bulb under a suitable temperature, compare with traditional incandescent lamp bulb, its life-span can reach more than 30000 hours, on average put calculating in 4-6 hour each evening, then can use more than 10 years.The driving power 7 that is electrically connected with lamp holder 1 is installed in the described lamp socket 2, the top of lamp socket 2 be equipped with can be reflective LED lamp plate 3, preferably can on described lamp socket 2 and LED lamp plate 3,

corresponding screw

23,31 be set respectively, LED lamp plate 3 is fixedly mounted on the lamp socket 2 by screw 6, and screw 6 passes to be tightened behind the screw 23 and in screw 31 LED lamp plate 3 is fixedly mounted on the lamp socket 2; Certainly, LED lamp plate 3 also can be fixed on the lamp socket 2 by the form that is coated with glue bond or buckle.LED lamp plate 3 that can be reflective can be collected the light that led light source 4 sends, so that the light that led light source 4 sends transmits from transparent lamp shade 5 after 3 reflections of LED lamp plate, the LED bulb of LED lamp plate that can be reflective is installed in the conventional art, improved greatly the light extraction efficiency of the light that led light source 4 sends, increase the under equal conditions brightness of LED bulb, saved the energy.Compare with conventional bulb, this its brightness of LED bulb of 3W is equivalent to the brightness of conventional incandescent 20W, and this its brightness of LED bulb of 5W is equivalent to the brightness of traditional 40W incandescent lamp, energy-conservationly reaches 80% ~ 85%.
