Description

The LED flashlight of tunable optical

Technical field

The utility model relates to the LED flashlight in a kind of flashlight lighting field, particularly tunable optical.

Background technology

The flashlight life appliance that is absolutely necessary in daily life, present flashlight dimming mode is: the device front that the single face convex lens is fixed on a push-and-pull, realizes the variable in distance of LED and single face convex lens, realize dimming effect, but there is following defective in this series products:

1) be not have the length fixed effect, and different light modulation positions, can cause the length of ligthing paraphernalia to differ, in special placement occasion, because of the variation of length, actual illumination is placed and can be had problems;

2) because of the variation of length, on waterproof requirement, can't accomplish effective waterproof;

3) when using under battle conditions, if adjust what a available effects, because colliding unexpectedly or fall, and cause the variation of illuminating effect, might actual user person be damaged, use safety inadequately.

The utility model content

The purpose of this utility model is to provide a kind of to need not to change entire length and just can realize dimming effect in order to solve above-mentioned the deficiencies in the prior art, and can play effective waterproof and improve the LED flashlight of the tunable optical of safety in utilization.

To achieve these goals, the LED flashlight of the tunable optical that the utility model is designed, comprise protecgulum, light source, lens, rotary adjusting head, fixed station, the flashlight bar, tubular shape conductor, switch and bonnet, described rotary adjusting headgear is connected on the outside of tubular shape conductor, flashlight bar inside is the dead slot structure, in the flashlight bar, be provided with power supply, described lens are fixed on the rotary front end of regulating head, described light source is fixed on the front end of tubular shape conductor by fixed station, described switch is located on the bonnet, the front end of flashlight bar is provided with the conductive holder of dead slot structure, one end of described conductive holder is provided with the contiguous block that is connected cooperation with power supply, the point diameter of described tubular shape conductor is greater than the rear end diameter, and the front end spiral of tubular shape conductor is connected on the inwall of rotary adjusting head, and the rear end spiral of tubular shape conductor is connected on the inwall of conductive holder.

By above-mentioned design, as long as by the rotary adjusting head of left rotation and right rotation, drive tubular shape conductor and do rectilinear motion, move forward or backward, realize need not to change the entire length of flashlight, by the inner zoom of flashlight, thereby according to the requirement adjustment focusing of oneself, the control aperture size is freely set the long-pending size of face to be illuminated, thereby has guaranteed the security of using and effectively improved water proofing property.

In order to play effective fixation, the outer wall of the front end of described conductive holder is provided with the reinforcing ring that cooperates with the front end of flashlight bar.

In order to play position-limiting action, the front end part of the described conductive holder torch bar that reaches plays spacingly by reach focal length that the part of torch bar exchanges the light time of conductive holder, realizes best dimming effect.

Front end described in the above-mentioned literal namely refers to the flashlight lighting direction, and described rear end namely refers to and the illumination rightabout.

The LED flashlight of the tunable optical that the utility model obtains, during work, change rotary adjusting head by hand-screw, realization need not to change the entire length of flashlight,, thereby focus the control aperture size by the inner zoom of flashlight according to the requirement adjustment of oneself, freely set the long-pending size of face to be illuminated, thereby guaranteed the security of using and effectively improved water proofing property.
