Abstract

The utility model relates to an LED (Light-Emitting Diode) electric torch capable of changing light colors, comprising an electric torch body and an electric torch head, wherein the electric torch head is provided with a reflecting cup and a backward screwing cap in openings on the front and back ends respectively; an inner end face of the backward screwing cap is connected with a rotating shaft along a central axis; the other end of the rotating shaft is fixed with a lens frame; a lamp panel provided with an LED lamp is fixed between the lens frame and the backward screwing cap; the lens frame corresponding to the LED lamp is provided with a plurality of lenses with different colors in principle directions; and when the lens frame is rotated, the light of the LED lamp is reflected out of the electric torch head by the reflecting cup through the lenses with different lenses. In operation, when the backward screwing cap is rotated, the rotating shaft is rotated accordingly, so the lens frame on the other end of the rotating shaft is rotated; and a plurality of light-through lenses with different colors can be arranged on the lens frame, and when the light of the LED lamp close to the lenses with different colors is reflected out of the electric torch head by the reflecting cup through the lenses, the color changing function of the electric torch is realized.

Description

A kind of LED flashlight that changes Light Color

Technical field

The utility model relates to a kind of flashlight technical field, especially a kind of LED flashlight that changes Light Color.

Background technology

At present; The LED illuminator is because low, the long service life of its power consumption; So be widely used in the various lighting apparatus and develop rapidly, hand-held LED torch is no exception, and various styles occur in succession; But present LED flashlight on the market generally all is single entry light or wants manual dismounting eyeglass change color, uses cumbersome, convenient inadequately.

Summary of the invention

The purpose of the utility model is to solve the deficiency of above-mentioned prior art, and improves a kind of simple and reasonable for structurely, and color replacing mechanism is arranged in the tube head, only needs through the back spiral cover on the rotation lamp holder LED flashlight that can change Light Color.

The utility model solves the technical scheme that its technical problem adopted: a kind of LED flashlight that changes Light Color; Comprise stack shell and tube head, it is characterized in that the front and back ends opening of said tube head is separately installed with reflector and back spiral cover; Back spiral cover inner face is connected with rotating shaft along central axis; The rotating shaft other end is fixed with lens hanger, and lens hanger and back are fixed with the lamp plate of band LED lamp between the spiral cover, is provided with the eyeglass of a plurality of different colours on the lens hanger of corresponding LED lamp by the principle direction; Through rotating lens hanger, the eyeglass that makes the light of LED lamp see through different colours goes out outside the tube head through the reflector back reflection; The LED flashlight of this structure through rotating the back spiral cover, makes rotating shaft follow rotation during use; The lens hanger of the rotating shaft other end rotates, owing on the lens hanger transmission lens of polylith different colours can be set, the eyeglass that makes light near the LED lamp of eyeglass see through different colours goes out outside the tube head through the reflector back reflection; Accomplish the colour changing function of flashlight; Make flashlight possess the lighting effect of different colours, and use simply, it is white, red, yellow, blue, green etc. that the color on the eyeglass can be set to as required.

The utility model can also adopt following technical measures to solve: said back spiral cover inner face is extended with central shaft; Be arranged with the rotating disk of band ring gear on the central shaft; Ring gear bridle joint on the rotating disk has external gear; It is fixing that rotating shaft one end is connected with the centre bore of external gear, and the other end passes behind the lamp plate to be connected with lens hanger and fixes; Rotation back spiral cover makes external gear follow the rotating disk toe joint and rotates, thereby is the rotary power that provides of rotating shaft, and it is simple and reasonable for structure, ring gear and external gear meshing, and compact conformation, durable, simultaneously after rotation during spiral cover, play and slow down and the effect of generation damping.

Said reflector inboard has light inlet, and LED lamp, eyeglass and light inlet are located on the same axis, forms linear light path, accomplishes the colour changing function.

The beneficial effect of the utility model is: a kind of LED flashlight that changes Light Color of (1), the utility model; Through rotating the back spiral cover, make rotating shaft follow rotation during use, the lens hanger of the rotating shaft other end rotates; Because the transmission lens of polylith different colours can be set on the lens hanger; The eyeglass that makes light near the LED lamp of eyeglass see through different colours goes out outside the tube head through the reflector back reflection, accomplishes the colour changing function of flashlight, makes flashlight possess the lighting effect of different colours; And use simply, it is white, red, yellow, blue, green etc. that the color on the eyeglass can be set to as required.

(2), a kind of LED flashlight that changes Light Color of the utility model, the structure that ring gear bridle joint external gear is installed on the back spiral cover is the rotary power that provides of rotating shaft; It is simple and reasonable for structure; Ring gear and external gear meshing, compact conformation is durable; Simultaneously after rotation, during spiral cover, play the effect of slowing down and producing damping.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

To shown in Figure 2, a kind of LED flashlight that changes Light Color comprises stack shell 1 and tube 2 like Fig. 1; It is characterized in that; Said 2 front and back ends opening is separately installed with reflector 3 and back spiral cover 4, and back spiral cover 4 inner faces 401 are connected with rotating shaft 5 along central axis, and rotating shaft 5 other ends are fixed with lens hanger 6; Be fixed with the lamp plate 8 of band LED lamp 7 between lens hanger 6 and the back spiral cover 4; Be provided with the eyeglass 9 of a plurality of different colours on the lens hanger 6 of corresponding LED lamp 7 by the principle direction,, eyeglass 9 that the light of LED lamp 7 sees through different colours gone out outside the tube 2 through reflectors 3 back reflections through rotating lens hanger 6; The LED flashlight of this structure; Through rotating back spiral cover 4, make rotating shaft 5 follow rotation during use, the lens hanger 6 of rotating shaft 5 other ends rotates; Since on the lens hanger 6 the polylith different colours can be set transmission lens 9; Eyeglass 9 that light near the LED lamp 7 of eyeglass 9 sees through different colours is gone out outside the tube 2 through reflectors 3 back reflections, accomplish the colour changing function of flashlight, make flashlight possess the lighting effect of different colours; And use simply, it is white, red, yellow, blue, green etc. that the color on the eyeglass 9 can be set to as required.
