Abstract

The utility model relates to an illuminating lamp, in particular to an LED (light-emitting diode) fluorescent lamp tube which comprises a lamp tube and lamp caps arranged at both ends of the lamp tube, wherein the lamp cap comprises a lamp tube sleeve, a rotary cover and a safety valve, the rotary cover is installed on the lamp tube sleeve, the safety valve is installed in the rotary cover, two supporting legs are arranged in the safety valve, through holes for the supporting legs to pass through are arranged on the rotary cover, a switch sheet is arranged in a space formed between the rotary cover and the lamp tube sleeve, the safety valve can axially translate relative to the rotary cover, and contact pins are conducted after the supporting legs are in contact with the switch sheet. The safety LED fluorescent lamp tube is not powered on when the contact pins are not installed on a lamp socket so that people have no danger of electric shock when touching the contact pins, therefore the electric shock is avoided and potential safety hazard is eliminated.

Description

A kind of safety-type LED fluorescent tube

Technical field

The utility model relates to a kind of lighting, especially a kind of LED fluorescent tube.

Background technology

The LED fluorescent tube generally comprises a bar shaped fluorescent tube and is located at the lamp holder of lamp tube ends, lamp holder is provided with the contact pin that is used to conduct electricity, because fluorescent tube is longer, so general elder generation when mounted inserts lamp socket with the contact pin of an end, and then the contact pin of the other end is inserted lamp socket, but because when end contact pin insertion lamp socket, fluorescent tube has produced electrical connection, if be exposed on the external the contact pin of the uninstalled other end still so people run into, then there is great potential safety hazard in situation about might get an electric shock.

Summary of the invention

The purpose of this utility model is to provide a kind of LED fluorescent tube that the electric shock situation takes place, security is good of avoiding.

To achieve these goals, the utility model adopts following structure:

It comprises a fluorescent tube and is located at the lamp holder of lamp tube ends, be respectively equipped with the contact pin that is used to conduct electricity on the lamp holder, described contact pin is exposed to outside the lamp holder, its improvement is: lamp holder comprises light tube jacket, swivelling cover and safety valve, described swivelling cover is installed on the light tube jacket, safety valve is installed in the swivelling cover, there are two legs described safety valve inside, swivelling cover is provided with the through hole that passes for leg, be provided with switch shrapnel in the space that described swivelling cover and light tube jacket form, described safety valve can be with respect to swivelling cover translation vertically, contact pin conducting behind the leg contact-making switch shell fragment.

Preferably, be provided with spring between described safety valve and the light tube jacket.

Preferably, described light tube jacket is provided with an opening, is provided with pushing lock in the opening, and described pushing is locked and is provided with a screens, and described swivelling cover is provided with a plurality of bayonet sockets, screens and the cooperation decision fluorescent tube of different bayonet sockets and the angle of lamp socket.

Safety-type LED fluorescent tube of the present utility model is by installing a safety valve in the contact pin outside, make contact pin no power when not being installed to lamp socket, even run into the danger that there is not electric shock in contact pin yet, when needs are installed, safety valve slides to swivelling cover, leg contact-making switch shell fragment, install and energising thereby finish, after installing an end, the contact pin of the other end is not energising still, gets an electric shock when having avoided the contact pin misconnection of user and the other end to touch, only when the use same procedure is in place fluorescent tube, safety valve is just opened energising. and avoid the generation of getting an electric shock, eliminated potential safety hazard.

The utility model purpose, function and advantage will be in conjunction with the embodiments, are described further with reference to accompanying drawing.

The specific embodiment

Shown in Fig. 1-4, the safety-type LED fluorescent tube of present embodiment comprises a fluorescent tube 1 and is located at the lamp holder at fluorescent tube 1 two ends, be respectively equipped with the contact pin 2 that is used to conduct electricity on the lamp holder, described contact pin 2 is exposed to outside the lamp holder, lamp holder comprises light tube jacket 3, swivelling cover 4 and safety valve 5, described swivelling cover 4 is installed on the light tube jacket 3, safety valve 5 is installed in the swivelling cover 4, there are two legs 51 described safety valve 5 inside, swivelling cover 4 is provided with the through hole 41 that passes for leg 51, be provided with switch shrapnel 6 in the space that described swivelling cover 4 and light tube jacket 3 form, contact chip 9, and PCB10, described safety valve 5 can move vertically with respect to swivelling cover 4, behind the leg 51 pull switch shell fragments 6, contact pin 2 is conducting to contact chip 9 by switch shrapnel 6, and contact chip 9 is welded on the PCB10, and PCB10 is connected with the circuit of inside. and when not installing, keep leg 51 and switch shrapnel 6 to disconnect in order to make safety valve 5, and safety valve 5 can reset when the dismounting fluorescent tube, is provided with spring 7 between described safety valve 5 of present embodiment and the swivelling cover 4.

Owing to adopt the fluorescent tube of LED making now, luminous have certain directive property, can regulate angle between fluorescent tube and the lamp socket when mounted in order to make fluorescent tube, present embodiment is provided with an opening 31 on described light tube jacket 3, be provided with pushing lock 8 in the opening 31, described pushing lock 8 is provided with a screens 81, and described swivelling cover 4 is provided with a plurality of bayonet sockets 42, screens 81 and the cooperation decision fluorescent tube of different bayonet sockets 42 and the angle of lamp socket.

During use, contact pin 2 no power when not being installed to lamp socket, even run into the danger that there is not electric shock in contact pin 2 yet, when mounted, contact pin 2 is inserted lamp socket B, when contact pin inserts lamp socket B fully, safety valve 5 with leg 51 pull switch shell fragments 6, is installed and energising thereby finish under the reaction of lamp socket B, after installing an end, the contact pin of the other end still is in not "on" position, gets an electric shock when having avoided user and the misconnection of other end contact pin to touch, and only fluorescent tube is just switched on after making fluorescent tube be fit into lamp socket fully, avoid the generation of getting an electric shock, eliminated potential safety hazard.

The above only is a preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
