Description

A kind of LED type energy-saving bulb

Technical field

The utility model relates to a kind of electric consumption on lighting light source, particularly a kind of LED type energy-saving bulb.

Background technology

The energy-saving bulb that generally uses at present all is a daylight cast energy-saving bulb; Its structure comprises lamp holder, illuminator and circuit board; Lamp holder comprise pedestal be located at the link that refuting on the pedestal connects external power, illuminator is the crooked fluorescent tube that is fixedly connected on the pedestal, circuit board is loaded in the pedestal; Refute the link that connects external power and be electrically connected with fluorescent tube through circuit board, its modeling structure is of long duration.

Since the LED lamp compare with fluorescent lamp have low power consuming, environmental protection, high brightness, advantage such as sturdy and durable, so people develop LED type energy-saving bulb.Present existing LED type energy-saving bulb; Just like No. 200820227727.3 disclosed a kind of great power LED five surface light-emitting lamps of Chinese patent; Be on the mounting plane around the square aluminium alloy heat radiation lamp body, the LED sidelight source that quantity equates to be installed; On the aluminium alloy disk of front end the LED front light-source is installed, the rear end connecting thread interface of aluminium alloy heat radiation lamp body.The volume of the illuminator of this kind bulb particularly sectional area ratio is bigger, causes the illuminator outside to be not easy to be provided with even light shield, and its uniformity of luminance is relatively poor; Another is the each several part of this kind bulb structure that is bonded as one; When needing repairing, damage is difficult to take apart; Part is keeped in repair or changed to inconvenience to led drive circuit; Because be significantly less than LED lamp pearl the service life of led drive circuit, so cause do not reach due service life in service life of LED type energy-saving bulb.

Summary of the invention

Particularly sectional area is excessive in order to overcome the illuminator volume that has LED type energy-saving bulb now; The illuminator outside is not easy to be provided with diffuser; The bulb each several part structure that is bonded as one is damaged and is difficult to take apart the defective that part was keeped in repair or changed to inconvenience to led drive circuit when needing repairing; The utility model provides a kind of improved LED type energy-saving bulb, can overcome the defective of prior art.

The utility model solves the technical scheme that its technical problem adopted: a kind of LED type energy-saving bulb, comprise lamp holder, illuminator and led drive circuit plate, and lamp holder comprises pedestal and is located at the link that refuting on the pedestal connects external power; Illuminator is fixedly connected on the pedestal; The led drive circuit plate is loaded in the pedestal, refutes the link that connects external power and is electrically connected with illuminator through the led drive circuit plate, and it is characterized in that: said illuminator comprises even light shield, mount pad and Column being luminous; Wherein Column being luminous is fixed on the mount pad; Column being luminous surrounds its sidepiece by at least three LED lamp pearl plates, and the Column being luminous top also is fixed with a LED lamp pearl plate, is separately installed with some LED lamp pearls on the said LED lamp pearl plate; Mount pad is slidingly fitted in the pedestal inboard by the slip location structure on it; Even light shield covers on the Column being luminous outside and is fixed on mount pad or the pedestal, and the led drive circuit plate is installed in the cavity that mount pad is inboard and the pedestal inboard constitutes, and pedestal, mount pad and even light shield are tightened together by screw.

The said mount pad of technique scheme is slidingly fitted in the pedestal inboard by the slip location structure on it, can be the locating slot by the mount pad outside, is slidingly fitted on the inboard location fin of pedestal; Perhaps can be location fin, be slidingly fitted on the inboard locating slot of pedestal by the mount pad outside.

The said locating slot by the mount pad outside of technique scheme is slidingly fitted on the inboard location fin of pedestal, and even light shield mounting disc edge also can be provided with the locating notch that is slidingly matched with the inboard location fin of pedestal.

The said Column being luminous of technique scheme can surround its sidepiece by four LED lamp pearl plates, and the cross-sectional profiles of even light shield can be four arc evagination connecting line moulding of a sealing.

Four camber lines of the cross-sectional profiles of the said even light shield of technique scheme can be that size is identical.

The said pedestal of technique scheme, mount pad and even light shield are tightened together by screw, can be to pass the nail hole on the even light shield by screw, pass the nail hole on the mount pad again, and threaded engagement is on the screwed hole of pedestal again.

The beneficial effect of the utility model is: because pedestal, mount pad and even light shield are tightened together by screw; Make bulb conveniently to split; To keep in repair or when changing part led drive circuit; Being easy to just can be with taking out in the cavity that led drive circuit is inboard from mount pad and the pedestal inboard constitutes, and the convenience of keeping in repair and changing part has guaranteed that LED type energy-saving bulb can reach due service life; Because mount pad is slidingly fitted in the pedestal inboard by the slip location structure on it; Also can be provided with the locating notch that is slidingly matched with the inboard location fin of pedestal on the even light shield, guarantee to take apart behind the LED type energy-saving bulb again convenience, accuracy and reliability that row is installed; Because illuminator adopted the less Column being luminous of sectional area, institute is so that be provided with even light shield in the Column being luminous outside, and guaranteed LED lamp pearl and the distance between the even light shield on the Column being luminous, effectively reaches the purpose with lamp pearly-lustre line homogenising.In addition; When adopting four LED lamp pearl plates, Column being luminous surrounds the situation of its sidepiece; The cross-sectional profiles of even light shield is four arc evagination connecting line moulding of a sealing; Lamp pearl on a slice sidepiece lamp pearl plate all faces toward an outer convex globoidal of even light shield like this, can further increase the distance between lamp pearl and the even light shield, improves lamp pearly-lustre line uniformization effect.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
