Abstract

The utility model discloses a LED rapid zoom lighting device, comprising a body, a power supply apparatus placed inside the body and a LED provided at the front end of the body which constitutes a power supply connection with a circuit board and the power supply apparatus. An optical axis in front of the LED is provided with a convex lens capable of moving back and forward relative to the LED and the relative distance between the said LED and the said convex lens changes within the range of two times of the convex lens focus distance. With the high brightness of the LED and the focus function of the convex lens with various focusing distances, the utility model is capable of focusing strong brightness in long distance lighting and scattering the light to the large area in short distance lighting with the even light spot as the one with the long distance lighting only by adjusting the micro distance between the said LED and the said convex lens, thus the device is fast to adjust and operate. Further, the lighting device is not provided with a reflecting cup and easy to carry and use in special places with a few elements, small volume and compact structure.

Description

The LED rapid zooming illuminating apparatus

Technical field

The utility model is about a kind of lighting device, is meant a kind of LED rapid zooming illuminating apparatus especially.

Background technology

The standing portable lighting device of people is generally flashlight in the daily life.The adjustable flashlight of tradition is by the turn bulb socket, because the lamp pearl is globe-type luminescence, adjusts the front and back position of electroluminescent lamp pearl in reverberation bowl, realizes the far and near strong and weak variation adjustment of flashlight irradiation.But in this zoom mode, because the luminous intensity of lamp pearl and to regulate distance far away limited and can't adapt to the needs of actual life.If adopt LED to make light source, because LED is the single face light source, can't launch light backward, so reverberation bowl can't realize adjusting far and near irradiation.People have also invented the various devices of regulating far and near illumination by research, as adjustable lighting devices of disclosed distance such as Chinese patent CN01224488.0, CN03228324.5, CN03224922.5.

But scheme used in aforementioned several patent roughly all adopts two groups of Different Light, and its distance is that the change by Different Light realizes that complex structure is to more then realizing.For the use in some special places, as far and near distance require from closely to the adjusting of (as about) far away, as in the modern military war and public security police's night operations to 30 meters, the street fighting of going down town, upstairs with downstairs, need under the situation of telefocus between the Lou Yulou or the like, astigmatism then be can't see; And for example assault of fortified positions enters in the building, stair, and the situation of forcing open the door or the like if be focused into a point, does not just have the comprehensive visual field, and this just needs the light source of a scattering.

The utility model content

The purpose of this utility model is to provide a kind of volume little, can short distance realize regulating the LED rapid zooming illuminating apparatus that far and near distance throws light on.

For achieving the above object, solution of the present utility model is: a kind of LED rapid zooming illuminating apparatus mainly comprises body, supply unit and LED; Supply unit places body, LED is located at the front end of body, LED forms power supply by circuit board and supply unit and connects, wherein be provided with the convex lens that move forward and backward of LED relatively on the optical axis in LED the place ahead, this LED variable in distance of these convex lens relatively is in the two focus length scope of convex lens.

Described body is provided with the adjusting device that the relative LED of these convex lens is moved forward and backward.

Described adjusting device is the sliding sleeve that slides along the body front and back in body portion sheathed, and this sliding sleeve front end is established gland, establishes convex lens between gland and sliding sleeve; In body upper sliding sleeve stroke, be arranged with water proof ring.

Described adjusting device is an adjustment cover, and this adjustment cover front end is established gland, establishes convex lens between gland and sliding sleeve, and described adjustment cover is screwed onto on the body by quick screw thread.

Described adjusting device is the sliding sleeve that slides along the body front and back in body portion sheathed, establish a cannelure on this sliding sleeve rear portion, be provided with one " L " shape suspension member in cannelure, be provided with two draw-in grooves on body, the jut adjustable ground of " L " shape suspension member is articulated in two draw-in grooves on the body.

Described LED holder front end is provided with retaining matter.

Described convex lens are single convex lens.

This LED relatively variable in distance scope of these convex lens is 0 to 35mm.

Described rear body is provided with stake body.

After adopting such scheme, because the utility model utilizes the adjusting of distance between LED and the convex lens to change the illumination that can realize far and near distance, utilized LED brightness height, the focusing of the different focal of convex lens, only need to adjust the variation of microspur between the two, it is strong to realize that the long distance illumination focuses on brightness, closely the big function of strary lighting area, and the hot spot of D﹠N is average, thereby governing speed is fast, operation is rapid; In addition, need not reflector in this lighting device, and parts are few, then little, the compact conformation of volume is so that carry and be applied to special place.

Fig. 2 is the three-dimensional exploded view of another embodiment of the present utility model;

Fig. 3 is the three-dimensional exploded view of an embodiment more of the present utility model.

The specific embodiment

As shown in Figure 1, LED rapid zooming illuminating apparatus of the present utility model mainly comprises body 1, supply unit (not shown), light-emitting component 2, sliding sleeve 3 and single convex lens 5;

Supply unit is that battery is to place body 1;

Light-emitting component 2 is that a LED21 is fixed on the circuit board 22, and circuit board 22 belows are provided with conducting strip 23, and circuit board 22 is fixed on the holder 24, and holder 24 is screwed onto the front end of body 1; LED21 can have epoxy resin that light source is once focused on and form optically focused LED when encapsulation;

LED21 forms power supply by circuit board 22, conducting strip 23 with battery and connects;

Sliding sleeve 3 is a cylindrical shell, and front end is established gland 4, at

gland

4 and 3 of sliding sleeves single convex lens 5 is set, and these list convex lens 5 are provided in a side of on the optical axis in LED21 the place ahead; Sliding sleeve 3 is socketed on the body 1 and can slides along body 1 front and back, is provided with water proof ring 11 on body 1, and this sliding sleeve 3 is by locating with the friction of water proof ring 11.

Can be equiped with transparent watertight lid 6 in addition in the front portion of light-emitting component 2.

For the illumination intensity that makes light is bigger, before led circuit plate 22, is close to led circuit plate 2 and is provided with reflecting piece 7.

During use, only need pulling sliding sleeve 3, when between one to the two times focal length of LED21 at single convex lens 5, the light that single convex lens 5 send LED21 focuses on place far away, when pulling sliding sleeve 3, when in one times of focal length of LED21 at single convex lens 5, the light that LED21 sends out is dispersed through behind the convex lens 5, can only illuminate than close-target, this LED21 variable in distance of these convex lens 5 relatively is in the two focus length scope of convex lens, and promptly the short distance in 0 to 35mm is regulated the adjusting that can realize the illumination of the utility model lighting device far and near distance.
