Description
Technical field
The utility model relates to the portable torch that is used to throw light on, and is meant a kind of changeable smooth flashlight especially.
Background technology
Along with the development trend of energy-saving and emission-reduction, LED obtains application more and more widely with characteristics such as its energy-conserving and environment-protective, luminous efficiency height, life-span length, and LED is applied to various illuminations place as a kind of novel solid light source.Flashlight is an illuminations commonly used during people live, and mostly existing widely used LED flashlight beam is fixing, promptly can't adjust the distance of light beam, therefore can't be in response to the demand of various varying environments.For improving the functional of LED flashlight lighting; Like brightness of illumination and illumination distances scope certain variation is arranged,, varifocal LED flashlight occurred to adapt to the needs of different places illumination; It mainly is through be provided with the optics convex lens that a relative LED lamp can move forward and backward in LED lamp the place ahead; Or the relative optics convex lens of LED can move forward and backward, thus realize flashlight closely big, the brightness of illumination zone evenly be floodlight, realize at a distance that the focus illumination scope is little and characteristics that the brightness height is.Only need in actual the use the relative optical lens of adjustment LED lamp between the two the quick variation of microspur can realize changing fast beam angle, effective application is in special place.But the floodlight that occurs on the market or the variable light flashlight of optically focused move up and down focusing as focusing up and down with the gear driven convex lens or driving light source with structures such as gears, when flashlight beam is floodlight, have the big angle of divergence, but the effect of large tracts of land projection illumination; When light beam is optically focused, have high order focusing, the characteristics of high strength telecurie irradiation, this kind variable light flashlight can be in response to various lighting environment.But the operation, structure, accessory etc. that have the flashlight of this kind function on the market are all comparatively numerous and diverse, and cost is very high, and damage easily.
In view of this, the design people is not to attaining perfect many disappearances and the inconvenience that causes in the design of above-mentioned flashlight structure, and deeply design, and the active research improvement has a fling at and development and Design goes out the utility model.
The utility model content
The purpose of the utility model is to provide a kind of simple in structure, easy to operate changeable smooth LED flashlight, to be applicable to various lighting environment.
In order to reach above-mentioned purpose, the solution of the utility model is:
A kind of changeable smooth LED flashlight; Comprise the head that is provided with reflector and optical mirror slip, the stack shell that is provided with switch and afterbody, an end of stack shell is connected with head, and the other end is connected with afterbody; Be provided with the LED lamp socket in the end that stack shell is connected with head and be located at the LED lamp on the LED lamp socket; Be provided with battery in the end that stack shell is connected with afterbody, battery and LED lamp electrically connect, and it is characterized in that: an end of this reflector is nested with on the LED lamp socket; Optical mirror slip is positioned at the other end of reflector, and head is threaded with stack shell.
This changeable smooth LED flashlight also comprises an eyeglass trim ring, and this eyeglass trim ring is placed on the head, and said optical mirror slip is located in this eyeglass trim ring.
One end inwall of said head and the socket of eyeglass trim ring is provided with a cannelure, and reflector is located at annular lip that should cannelure, and this flange places in the cannelure.
After adopting said structure, the changeable smooth LED flashlight of the utility model utilizes being threaded of head and stack shell, makes head interior reflector and optical mirror slip and the distance that is fixedly arranged between the LED lamp of stack shell changes, and just can reach the effect of floodlight or optically focused.The changeable smooth LED flashlight of the utility model adopts easy structure, minimum cost, can the manual adjustment focal length, and optically focused or floodlight, the convenient execution.Utilize simple optical principle, projected light beam focuses on floodlight and only needs rotation head, can easily control required light, to be applicable to various lighting environment.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Shown in Figure 1 is the preferred embodiment of a kind of changeable smooth LED flashlight of the utility model, as shown in the figure, and a kind of changeable smooth LED flashlight 100 of the utility model comprises head 1, stack shell 2 and afterbody 3; One end opening of head 1 is provided with a cannelure 11, is provided with reflector 4 in this head 1, and the corresponding cannelure 11 of an end of reflector 4 is provided with the flange 41 of an annular, and flange 41 is placed on the cannelure 11, and reflector 4 is located in the head 1; One optical mirror slip 5 is located at flange 41 1 sides of reflector 4, and is located on the head 1 through an eyeglass trim ring 6.The other end of head 1 is threaded with stack shell 2; The other end of this stack shell 2 is connected with afterbody 3, and the end inside that stack shell 2 is connected with head 1 is installed with LED lamp socket 21, and LED lamp socket 21 is provided with LED lamp 7; Reflector 4 is nested with on LED lamp socket 21 with flange 41 relative other end activities; Be provided with battery 8 in stack shell 2 and the end that afterbody 3 is connected, battery 8 electrically connects with LED lamp 7, and stack shell 2 is provided with the switch 9 that control LED lamp opens and closes.
When user's desire is used the changeable smooth LED flashlight 100 of the utility model; Can select illumination beam according to actual conditions is floodlight or optically focused; Manually rotate the head 1 of flashlight 100; Reflector 4 and optical mirror slip 5 in the head 1 are moved with head 1, thereby change the distance between reflector 4 and optical mirror slip 5 and the LED lamp 7, select optimal lighting effect.When needing telecurie irradiation, rotation head 1 makes the counter-rotation of head 1 to stack shell 2, and the distance between optical mirror slip 5 and the LED lamp 7 is increased, and this moment, the light beam high order focusing was applicable to telecurie irradiation; When needing irradiation at short distance, rotate head 1 equally, head 1 is moved to stack shell 2 directions, the distance between optical mirror slip 5 and the LED lamp 7 is more and more little, and this moment, the angle of divergence of light beam was big, can closely shine on a large scale.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
