The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of multi-functional, varifocal, LED flashlight that can projection mark is provided.
A kind of LED flashlight that can projection mark that provides according to the utility model, comprise body, be installed in power supply, control circuit and LED in the described body, described LED is installed in the front end of described body, the front end sleeve of described body is equipped with the sliding sleeve that slides in front and back, on the described sliding sleeve lens are installed, the end of described body is provided with transparent membrane, and described diaphragm is positioned at the front side of described LED, and and described LED between at regular intervals, have mark layer on the described diaphragm.
A kind of LED flashlight that can projection mark that provides according to the utility model also has following attached technical characterictic:
When described sliding sleeve slided into maximum position, the distance between described diaphragm and the described lens was greater than one times of focal length of described lens.
Spacing between described diaphragm and the described LED be described lens focal length 0.4-0.6 doubly.
Described diaphragm is fixed on the end of described body by a pressure ring.
Described body end formed has spacing snap ring, and described snap ring matches with described sliding sleeve.
The rear portion of described sliding sleeve is formed with many and promotes convex tendon.
The sliding distance of described sliding sleeve is the focal length of one times of described lens.
A kind of LED flashlight that can projection mark that provides according to the utility model compared with prior art has following advantage: at first, the utility model is provided with the transparent membrane with mark in the LED front side, by focusing, mark on the described diaphragm can be projected at a distance, this mark can enrich function of use of the present utility model for emergency mark or cue mark; Secondly, only when sliding sleeve was adjusted to maximum position, it just understood projection to mark in the utility model, and LED and mark make this mark can not influence the irradiation of LED not a focus.

The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the embodiment of a kind of LED flashlight that can projection mark that provides at the utility model, comprise body 1, be installed in power supply 2, control circuit 3 and LED4 in the described body 1, described LED4 is installed in the front end 11 of described body 1, the front end 11 of described body 1 is set with the sliding sleeve 5 that slides in front and back, on the described sliding sleeve 5 lens 6 is installed.Said structure has been formed the LED flashlight of adjustable focal length in the prior art, and this kind flashlight is by adjusting sliding sleeve 5, thereby lens 6 on the adjusting sliding sleeve 5 and the distance between the LED4 reach size and the brightness of regulating flashlight irradiation aperture.Described lens 6 are generally convex lens.The difference of the utility model and prior art is: the end 12 of described body 1 is provided with transparent membrane 7, and described diaphragm 7 is positioned at the front side of described LED4, and and described LED4 between at regular intervals, have mark layer 71 on the described diaphragm 7.This mark layer 71 has mark, is SOS, or the mark of other effects.The described dark color that is labeled as, thereby imaging a long way off, and this image is a magnified image.The utility model is arranged on the front side of LED4 with diaphragm 7, and and LED4 between form a determining deviation, make image space and LED4 different of diaphragm 7, when routine irradiation use, mark can imaging, thereby can not influence radiation response.The utility model has mark function with traditional adjustable focus flashlight, can play crucial effect under special circumstances, has enriched the function of flashlight.
Referring to Fig. 3, in the foregoing description that the utility model provides, when described sliding sleeve 5 slided into maximum position, the distance between described diaphragm 7 and the described lens 6 was greater than one times of focal length of described lens 6.Promptly only when described sliding sleeve 5 moves to maximum position, described diaphragm 7 just can be positioned at image space, and when the no show maximum position, it can imaging.When this structure guarantees sliding sleeve 5 to maximum position, just can be the picture that is marked as on the diaphragm 7, the convenient use.
Referring to Fig. 3, in the foregoing description that the utility model provides, the spacing between described diaphragm 7 and the described LED4 be described lens 6 focal length 0.4-0.6 doubly.Present embodiment is 0.5, and promptly described spacing is half of lens 6 focal lengths.Said structure makes LED4 when imaging, and the mark on the described diaphragm 7 still is in scattering state, can imaging.
Referring to Fig. 2, in the foregoing description that the utility model provides, described diaphragm 7 is fixed on the end 12 of described body 1 by a pressure ring 71.Described pressure ring 71 plays fixation, is beneficial to the installation of diaphragm 7.
Referring to Fig. 3, in the foregoing description that the utility model provides, the end 12 of described body 1 is formed with spacing snap ring 13, and described snap ring 13 matches with described sliding sleeve 5.Described snap ring 13 has played spacing effect.When described sliding sleeve 5 slided into described snap ring 13, sliding sleeve 5 was in the maximum position of slip, was marked as picture on this moment described diaphragm 7.
Referring to Fig. 3, in the foregoing description that the utility model provides, the rear portion of described sliding sleeve 5 is formed with many and promotes convex tendon 51.Described promotion convex tendon 51 plays anti-skidding effect, is beneficial to promote described sliding sleeve 5 slips.
