Abstract

The utility model relates to a novel focusing flashlight. The novel focusing flashlight is provided with a head part, a lamp holder, a main body part and a tail part which are connected sequentially, wherein the head part comprises a fixing piece, a lens and a lamp bowl; the lamp holder is accommodated in the main body part; the tail part and the main body part are assembled together; a printed circuit board is arranged on the lamp holder; and a light-emitting diode (LED) lamp is arranged on the printed circuit board. The LED lamp is directly arranged on the printed circuit board, so focus can be adjusted, the structure of the flashlight is simplified, and the novel focusing flashlight is simple to operate and convenient to use.

Description

A kind of novel focus flashlight

Technical field

The utility model relates to a kind of flashlight, refers in particular to a kind of flashlight of adjustable focus.

Background technology

At home, in the entertainment place, flashlight is often used as a kind of movable light source yard in one's power.Common flashlight generally includes the body and the cylinder that is used for holding battery that include incandescent lamp.In the body parabolic lens or parabolic type reflector are installed, the filament of bulb is arranged in the focus of minute surface, and the front end of this body is installed a glass plate.Form certain elevation angle between the outward flange of the filament of bulb and parabolic type reflector, the light that this bulb sends, all be radiated on the parabolic type reflector greater than the light elevation angle and backward irradiation, then be reflected into parallel reverberation by the parabolic type reflector, this part light is useful beam.All the other light less than the elevation angle directly outwards penetrate from glass plate, this part light in most of the cases all is to have wasted, and the position of the bulb of this flashlight and parabolic type reflector is all fixed, can not regulate their distance, so the flashlight of the zoom more demand of people that can better satisfy.And the Zooming electric torch majority on the market is to add a zoom system, pancreatic system between the light supply apparatus of flashlight and light-emitting window, the hot spot that light supply apparatus is produced can change its rising angle, thereby so that flashlight can be adjusted its facula area size and brightness to satisfy people's multiple demand.Yet existing zoom system, pancreatic system complex structure and parts are more, and ease of use is relatively poor, thereby need a kind of simple in structure and can realize the flashlight of zoom purpose.

Summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, the focus flashlight of the lower and better performances of cost.

For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows: a kind of novel focus flashlight, it has head, lamp socket, body and the afterbody that connects in turn, described head comprises fixture, lens and lamp bowl, described lamp socket is housed in the body, afterbody and body fit together, and are provided with printed circuit board (PCB) on the described lamp socket, further are provided with the LED lamp on the described circuit board.

Further, described printed circuit board (PCB) is contained on the lamp socket by set screws.

Further, be assembled with conductive rivet on the described body, described conductive rivet is electrically connected with printed circuit board (PCB).

Further, be provided with shift knob on the described body.

Further, described printed circuit board (PCB) periphery is provided with at least one breach, and described screw is arranged in the corresponding breach printed circuit board (PCB) is assembled on the lamp socket.

Further, be assembled with battery in the described body, be provided with spring in the described afterbody and realize being electrically connected with described battery.

The novel focus flashlight of the utility model compared with prior art has following beneficial effect: realize focusing on the printed circuit board (PCB) by the LED lamp is arranged, simplified flashlight structure, not only reduced production cost, also improved simultaneously the reliability of product.

Description of drawings:

Fig. 1 is three-dimensional exploded view of the present utility model.

Fig. 2 is lamp socket assembly drawing of the present utility model.

Fig. 3 is lamp socket exploded view of the present utility model.

Fig. 4 is the printed circuit board (PCB) stereogram of the utility model lamp socket.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further.

Please refer to Fig. 1 to shown in Figure 4, a kind of novel focus flashlight of the utility model, it has head 1, lamp socket 2, body 3 and the afterbody 4 that connects in turn, described head 1 comprises fixture, lens 10 and lamp bowl (not shown), described lamp socket 2 is housed in the body 3, afterbody 4 fits together with body 3, is provided with printed circuit board (PCB) 20 on the described lamp socket 2, further is provided with LED lamp 21 on the described circuit board.

Described printed circuit board (PCB) 20 is assembled on the lamp socket 2 by screw 22.

Be assembled with conductive rivet 30 on the described body 3, described conductive rivet 30 is electrically connected with printed circuit board (PCB) 20.

Be provided with shift knob 31 on the described body 3.

Described printed circuit board (PCB) 20 peripheries are provided with at least one breach 23, and described screw 22 is arranged in the corresponding breach printed circuit board (PCB) is assembled on the lamp socket.

Be assembled with battery in the described body, be provided with spring in the described afterbody 3 and realize being electrically connected with described battery.

The utility model is realized focusing by the LED lamp is set directly on the printed circuit board (PCB), simplified flashlight structure, has not only reduced production cost, has also improved simultaneously the reliability of product.
