Description

The independent external flashlight of a kind of lamp socket

Technical field

The utility model belongs to a kind of flashlight in the electricity field hand-held lighting device, specifically belongs to a kind of and is equipped with relatively independently, external, and existing best radiating effect can carry out the flashlight of the flashlight LED lamp socket of brightness regulation and focus adjustment again easily.

Background technology

The lamp socket of flashlight generally all is parts as flashlight inside at present, and its major function is to be used for being connected and fixed the lamp pearl; The focusing function of flashlight mainly realizes by the screw thread that the rotating cylinder head is connected with stack shell; The flashlight of high-power light-emitting body has been installed, has been needed good heat sinking function, existing solution is to derive several fin, complex structure from lamp socket; Aspect adjusting brightness, prior art is that lamp socket is fixed in the tube head, realizes by the screw thread that the rotating cylinder head is connected with stack shell, can't realize focusing.

The utility model content

The utility model provides a kind of torch lamp holder structure of modified form, solves the defective in original technology, and flashlight can be focused, again can light modulation, also have best radiating effect, and structure is simple optimizing more.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:

Flashlight is divided into tube a head, lamp socket, three relatively independent funtion parts of stack shell, does not comprise mutually, tube, stack shell and lamp socket are by being threaded; Metal lamp socket directly contacts with LED, because the lamp holder shell exposes, the heat energy that produces in the course of the work of LED can be directly transferred to the external world by metal lamp holder so, realizes optimum heat radiation; Be connected with the tube head thread at the lamp socket front end, the rotating cylinder head drives reflector in the tube head, just can regulate the position of lamp pearl in reflector that is fixed on the lamp socket, realizes the function of focusing; A circuit board is fixed in the appropriate location in lamp socket, two negative pole input points of design on the circuit board, be respectively highlighted input point and low bright input point, low bright input point is drawn the direct and lamp socket conducting of lead, form the loop by lamp socket, stack shell, switch, battery, all the time conducting is opened switch and can be made torch low bright; Highlighted input point is located at the back of circuit board outer ring, not with the lamp socket conducting, but by the precession stack shell during to certain position directly and the stack shell conducting, form the loop by circuit board, stack shell, switch, battery, open switch and can make torch highlighted; Unscrew stack shell, stack shell and highlighted input point are disconnected, can make torch return to low bright state.

The beneficial effects of the utility model are:

Because lamp socket designs is become relatively independent external parts, make flashlight possess focusing, light modulation, heat radiation three big functions simultaneously, structure is optimized more, operates simpler, more convenient to use reliable.

The specific embodiment

Below in conjunction with accompanying drawing preferred implementation of the present utility model is done detailed description.

Flashlight is divided into tube 1,

lamp socket

2,3 three relatively independent funtion parts of stack shell, relatively independent; Tube 1 is connected with lamp socket pedestal 209 front end external screw threads 202 by internal thread 102; Stack shell 3 is connected with lamp socket pedestal 209 rear end internal threads 207 by front end external screw thread 301;

Metal lamp socket pedestal 209 directly contacts with LED201, because lamp socket pedestal 209 rear end parts directly expose, the heat energy that produces in the course of the work of LED201 can be directly transferred to the external world by metal lamp holder pedestal 209 so, realizes optimum heat radiation;

Be connected with tube 1 internal thread 101 at lamp socket 2 front end external screw threads 202, rotating cylinder head 1 drives tube 1 an interior reflector 101, just can regulate the position of LED lamp pearl 201 in reflector 101 in the lamp socket 2, realizes the function of focusing;

Fixing circuit board 204 in lamp socket pedestal 209, circuit board 204 1 sides are provided with low bright input point 205, at opposite side highlighted input point 206 is set, low bright input point 205 is drawn lead 203 direct and lamp socket pedestal 209 conductings, form the loop by low bright negative pole input point 205, lead 203, lamp socket pedestal 209, stack shell metal tube 303, switch 304, battery 302, the anodal input point 206 of circuit board, all the time conducting is opened switch and can be made torch low bright;

Highlighted input point 206 is located at outer ring, circuit board 204 back side, not with 209 conductings of lamp socket pedestal, but by precession stack shell 3 during to certain position directly and 303 conductings of stack shell metal tube, form the loop by highlighted negative pole input point 205, stack shell metal tube 303, switch 304, battery 302, the anodal input point 206 of circuit board, open switch and can make torch highlighted;

Unscrew stack shell 3, stack shell metal tube 303 and highlighted input point 205 are disconnected, can make torch return to low bright state.

In sum, the utility model is a kind of modified form flashlight lamp socket, by lamp socket designs being become relatively independent, external parts, can be by the high temperature that produces in the work of lamp socket pedestal conduction and high power illuminator, can also focus by the rotating cylinder head, can regulate brightness by the rotation stack shell again, simple to operate, convenient, reliable.

The above is a preferred embodiment of the present utility model only, and being not limited to the utility model only has this a kind of embodiment, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
