Background technology
Spotlight is meant the lamp with optically focused camera lens and/or reflection lens, and the light that is used for that light source is sent is concentrated and penetrated, and makes it be confined to certain scope and so on.General spotlight mainly comprises lamp pearl and lens, and lens place the front of lamp pearl, and light that the lamp pearl sends is through the zone necessarily of directive behind the lens, and the distance between lamp pearl and the lens is the basic factor of decision aperture size and bright and dark light degree.The lamp pearl of tradition spotlight and the fixed distance between the lens are difficult for regulating, so be difficult in use the aperture size and the bright and dark light degree of light regulated, make the application function of spotlight limited, are unfavorable for the development of spotlight industry.
Summary of the invention
The purpose of the utility model provides a kind of through rotating the spotlight of adjustment aperture size and bright and dark light degree with regard to being in order to address the above problem.
The utility model is realized above-mentioned purpose through following technical scheme:
The utility model comprises lamp pearl holder, lens, lens carrier, outer ring, swing adapter sleeve, cover and preceding circle are rotationally connected; Penetrating direction with the light of said lens is the place ahead; The front end of the said cover that is rotationally connected is fixedly connected through circle before said with the front end of said lens carrier; Said lens are installed on the rear portion of said lens carrier and are positioned at the said cover that is rotationally connected, and said swing adapter sleeve is set in the outside of the said cover that is rotationally connected, and said swing adapter sleeve is connected with said outer ring; The front portion of said lamp pearl holder places in the said cover that is rotationally connected, and is provided with silk mouthful device between the inwall of the anterior outer wall of said lamp pearl holder and the said cover that is rotationally connected.
When the aperture size of needs adjustment spotlight and bright and dark light are spent; Circle before the rotation; The moving cover that is rotationally connected of preceding astragal rotates, and through silk mouth device, lamp pearl holder is moved at axial direction; Thereby change interior lamp pearl of lamp pearl holder and the distance between the lens on the lens carrier, reach the aperture size of adjustment spotlight and the purpose of bright and dark light degree.
Particularly, said silk mouthful device is: the said inwall that is rotationally connected cover is provided with spiral groove, and the anterior outer wall of said lamp pearl holder is provided with the adjusting projection corresponding with said spiral groove, and said adjusting projection places in the said spiral groove.This is a kind of simple in structure, effective silk mouthful device, and as required, a silk mouthful device also can adopt other structure.
More specifically, said spiral groove is three, is uniformly distributed on the inwall circumference of the said cover that is rotationally connected; Said adjusting projection is three, places respectively in three said spiral grooves.This structure makes lamp pearl holder have good balance easily, is convenient to move axially.
Further; The outer wall of said lamp pearl holder is provided with the limited impression of fore-and-aft direction; The rear end of said swing adapter sleeve is equipped with compressing tablet, and the inwall of said compressing tablet is provided with the spacing block set corresponding with said limited impression, and said spacing block set places in the said limited impression.The length of limited impression has determined the axially movable longest distance of lamp pearl holder, is decided according to the actual requirements.
Particularly, the cross section of said limited impression is semicircle, promptly is convenient to slide, and also is convenient to install.
As preferably, said swing adapter sleeve is connected through screw with said outer ring; The lamp pearl of said lamp pearl holder front end is a LED lamp pearl; Said lens are convex lens.
The beneficial effect of the utility model is:
The utility model can drive lamp pearl holder through circle before rotating and move at axial direction; Thereby change interior lamp pearl of lamp pearl holder and the distance between the lens on the lens carrier; Reach the aperture size of adjustment spotlight and the purpose of bright and dark light degree; Regulate very conveniently, make the application function of spotlight more perfect, help the development of spotlight industry; The utility model not only is applicable to desk lamp, floor lamp, stage lighting, commercial with various spotlights such as lamps, and is applicable to the various ornament lamps with lamp pearl and lens arrangement of whole lamp decoration industry.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As depicted in figs. 1 and 2; The utility model comprises lamp pearl holder 2, convex lens 12, lens carrier 15, outer ring 6, swing adapter sleeve 4, cover 11 and preceding circle 7 are rotationally connected; Penetrating direction with the light of convex lens 12 is the place ahead (i.e. below among the figure); Cover 11 the front end that is rotationally connected is fixedly connected through preceding circle 7 with the front end of lens carrier 15; Convex lens 12 are installed on the rear portion of lens carrier 15 and are positioned at the cover 11 that is rotationally connected, and swing adapter sleeve 4 is set in the outside of the cover 11 that is rotationally connected, and swing adapter sleeve 4 is connected through screw 5 with outer ring 6; The front portion of lamp pearl holder 2 places in the cover 11 that is rotationally connected; Be rotationally connected and evenly be provided with three spiral grooves 8 on cover 11 the inwall circumference; The anterior outer wall of lamp pearl holder 2 is provided with 10, three of three adjusting projections corresponding with three spiral grooves 8 and regulates projections 10 and place respectively in three spiral grooves 8; The lamp pearl 9 of lamp pearl holder 2 front ends is a LED lamp pearl.
As depicted in figs. 1 and 2; The outer wall of lamp pearl holder 2 is provided with the limited impression 1 of fore-and-aft direction; The rear end of swing adapter sleeve 4 is equipped with compressing tablet 3, and the inwall of compressing tablet 3 is provided with the spacing block set (in figure unmarked) corresponding with limited impression 1, and spacing block set places in the limited impression 1; The cross section of limited impression 1 is semicircle.
