Abstract

The utility model discloses a converged and diverged flashlight, the bulb base of which is equipped with a conic reflecting body formed by several elastic reflecting strips, the convergence or divergence of light by conic reflecting body is achieved by revolving bulb base to change radian of elastic reflecting strips. The utility model can achieve the objective by changing simply the radian of each reflecting strip with simple structure, low costs, and simple operation by advancing or retreating bulb base.

Description

A kind ofly gather, astigmatic flashlight

Technical field

The utility model relates to a kind of flashlight, refer in particular to have the gathering of optically focused and astigmatism functions simultaneously, astigmatic flashlight.

Background technology

The flashlight of commonly using generally comprises stack shell, is located at the bulb socket composition of interior battery of stack shell and stack shell front portion.Establish one in the bulb socket and be used for catoptrical concave mirror, the lamp pearl is positioned at the focus place of concave mirror.The light that the lamp pearl sends is through the directional light that reflects to form of concave mirror.In addition can or screw out bulb socket and make the lamp pearl, thereby the light that the lamp pearl is sent is dispersed or assembled the moving forward and backward of concave mirror focus by precession.But because lamp pearl displacement is limited, so poor effect.As adopting methods such as establishing the lamp pearl at diverse location also can reach poly-astigmatism functions is arranged simultaneously, but complex structure, the cost height.

The utility model content

The purpose of this utility model provide a kind of simple in structure, can have the gathering of optically focused and astigmatism functions, astigmatic flashlight simultaneously.

For reaching above-mentioned purpose, solution of the present utility model is: a kind ofly gather, astigmatic flashlight, mainly be made up of cylindrical shell, battery and bulb socket; Bulb socket is located at the leading section of cylindrical shell, LED forms a closed-loop path by a led circuit plate and battery and switch, wherein in bulb socket, establish a conical surface refractive body, this conical surface refractive body large end face overhead is in the front portion of bulb socket, the small end face overhead is on the led circuit plate, the LED lamp is stretched from conical surface refractive body small end face and is placed in the conical surface refractive body, and described conical surface refractive body is that some the elasticity reflecting piece system of enclosing forms.

Described elasticity reflecting piece is a sheet metal, and its top connects as one the formation covering of the fan, and this covering of the fan is rolled into aforementioned conical surface refractive body.

Described elasticity reflecting piece is the Elastic plastic-rubber sheet that is coated with reflective membrane, and this sheet is plugged in two cannelures of size and forms aforementioned conical surface refractive body.

The outer sheathed certain position of described conical surface refractive body concave surface ring.

After adopting such scheme, when screwing bulb socket, the anterior extruding of bulb socket elasticity reflecting piece, make the elasticity reflecting piece be deformed into arc, thereby this group elasticity reflecting piece forms the light reflection post-concentration that a concave mirror sends LED, when bulb socket unscrewed, sheet metal stretched under self tension force effect, and the light that LED sends is dispersed after reflection.The just simple radian that changes each reflecting piece of the utility model can be reached target, and therefore simple in structure, cost is low; Only need the spinning in and out bulb socket simultaneously, easy to operate simple.

The specific embodiment

As shown in Figure 1, 2 a kind of gathers, astigmatic flashlight, mainly is made up of cylindrical shell 1, battery (not shown) and bulb socket 2; Bulb socket 2 is screwed in the leading section of cylindrical shell 1, establish a conical surface refractive body 3 in it, its inner face is reflective, conical surface refractive body 3 is some elastic metallic reflecting piece 31, and elastic metallic reflecting piece 31 its tops connect as one the formation covering of the fan, and this covering of the fan is rolled into aforementioned conical surface refractive body 3, sheathed certain position concave surface ring 4 outside elastic metallic reflecting piece 31, one LED5 is arranged on the led circuit plate 6, and the large end face of conical surface refractive body 3 withstands on the front portion of bulb socket 2, and small end face withstands on the led circuit plate 6.LED5 stretches in the small end face that places conical surface refractive body.Afterbody at cylindrical shell 1 is connected with tail-hood 11, and tail-hood 11 connects a key switch 8, a sheathed button cap 9 on the button 81 of key switch 8, and button cap 9 is stretched in the through hole 111 that places tail-hood 11.LED5 forms a closed-loop path by led circuit plate 6 and battery, electric wire (not shown) and key switch 8.The cap 9 that pushes button during use makes key switch 8 closures, and LED is luminous.When screwing bulb socket 2, the anterior extruding of bulb socket elastic metallic reflecting piece 3, make elastic metallic reflecting piece 3 be deformed into arc, thereby spacing this group elastic metallic reflecting piece 3 down at alignment concavity ring 4 forms the light reflection post-concentration that a concave mirror sends LED5, when bulb socket 2 unscrews, elastic metallic reflecting piece 3 is stretched under self tension force effect, and the light that LED5 sends is dispersed after reflection.

Another embodiment of the utility model conical surface refractive body is for as shown in Figure 3, elasticity reflecting piece 3 ' is for being coated with the Elastic plastic-rubber sheet 31 ' of reflective membrane, sheet is plugged on big or small two cannelures, 32 ', 33 ' interior formation and bores into refractive body 3 ', big cannelure withstands on the front portion of bulb socket 2, and little cannelure withstands on the led circuit plate 6.
