Abstract

The utility model relates to a stage illuminating lamp, belonging to the mechanical engineering illuminating class. A small fan, a reflecting mirror, an optical source, an optical source lens, a pattern tray, a projecting lens, and a reflecting seat are orderly arranged in a casing seat; after the light of the optical source and the light which is reflected by an arc reflecting mirror are mixed, the illumination intensity is enhanced; after the lens focus of the light source is changed into the light beam, the light beam with various different shapes is projected out through the holes of the pattern plate; the light beam reaches the projecting lens and then focuses, and finally the light beam with various different shapes and colors is reflected out by the reflecting lens. The utility model has the effects that the illumination intensity is enhanced; the light beam is not diffused; the projection distance is far; the light and the shadow are varied.

Description

Stage lamp with light shadow change

The utility model belongs to the stage illumination, lighting light fixture of mechanical illumination class.

Stage lighting increases happy atmosphere, active scene for dancing party, concert, present stage lighting pattern is more, analyze from structure, great majority are to adopt to rotate color light source, cause multicoloured effect, but this class stage lighting illumination is strong inadequately, light spreads, projection distance is not far, beam shape, style dullness.

The purpose of this utility model is the weak point at above-mentioned stage lighting, a kind of stage lighting that shadow changes that has is provided, it mainly is in shell block, small fan, speculum, light source, light lens, style dish, projection lens, reflection seat is installed is in order formed.The light of light source is together with after mixing through the light that arc-shaped reflecting mirror reflected, strengthened illumination, after light lens is focused into light beam, can project various difform light beams through the sample hole of style dish again, arrive at projection lens through focusing on again, at last the reflecting optics by reflection seat reflects again, forms the light of various difformities, color, reaches illumination enhancings, light beam indiffusion, projection distance is far away and the effect of shadow variation.

The utility model is achieved in that a kind of stage lighting with shadow variation of design, and its primary structure is that small fan, speculum, light source, light lens, style dish, projection lens, reflection seat are installed in shell block in order.

The shell block that is the hollow elongated body, its place ahead downside is shaped on

Shell seat short slot.

The small fan of heat transmission is installed in the end of shell block.

Speculum curved and the coating light source is installed between light source and the fan.

Light source is installed in the place ahead of speculum, and is controlled by known switch.

The light lens that is used to focus on and is convex lens is installed in the place ahead of light source.

Be plate-like and be installed in the place ahead of light lens, be shaped on different shape pattern, sample hole that size is different on the style dish, install porose in the sample hole by the style dish of known motor driven rotary.

The projection lens that is used to focus on and is convex lens is installed in the place ahead of style dish.

Curved and revolvable reflection seat is installed in

In the inclined-plane in the shell seat short slot, be shaped on the light beam corresponding some reflecting optics emitted on the cambered surface of reflection seat with the opposite side projection lens.

Below in conjunction with the accompanying drawing illustrated embodiment, the utility model structure is elaborated:

Fig. 1 is the utility model light path system schematic diagram

Fig. 2 is the utility model structural representation

Fig. 3 is the utility model schematic perspective view

1-shell block 2-small fan 3-speculum

4-light source 5-light lens 6-style dish

7-projection lens 8-reflection seat 11-shell block short slot

62-hole, 61-sample hole sheet 81-reflecting optics

During enforcement, see also Fig. 1 to Fig. 3, make each assembly of the utility model earlier, have the stage lighting that shadow changes, it mainly is that small fan 2, speculum 3, light source 4, light lens 5, style dish 6, projection lens 7, reflection seat 8 are installed in shell block 1 in order.

The shell block 1 that is the hollow elongated body, its place ahead downside is shaped on

Shell seat short slot 11 is used for the output beam projection of reflection seat 8.

The small fan 2 of heat transmission is installed in the end of shell block 1.Purpose is that the heat that makes light source 4 continue luminous generation can access the heat radiation cooling, makes shell block 1 inner space unlikely overheated.

Speculum 3 curved and coating light source 4 is installed between light source 4 and the small fan 2, and it mainly acts on and is that the rear light that light source 4 is sent can be reflected by speculum 3, and its light is forward mixed, and strengthens illumination.

The light source 4 main emitting bulbs that adopt, light source 4 is installed in the place ahead of speculum 3, and is controlled by known switch.

The light lens 5 that is used to focus on and is convex lens is installed in the place ahead of light source 4, throws forward so that make the light of light source 4 focus on back one-tenth light beam through its.

Be plate-like and be installed in the place ahead of light lens 5 by the style dish 6 of known motor driven rotary, be shaped on different shape pattern, sample hole 61 that size is different on the style dish 6, install porose 62 in the sample hole 61, make light beam throw and form the light beam of these sample hole 61 shapes forward through various kinds hole 61.Make it have the effect of shadow of difformity pattern, the transparent apertures sheet 62 of different colours also can be housed respectively on sample hole 61, then the light beam that penetrates through style dish 6 forms different color, difform effect of shadow, and sample hole 61, hole sheet 62 can be pentalpha, circle, triangle, rhombus etc.

The projection lens 7 that is used to focus on and is convex lens is installed in the place ahead of style dish 6, and it will focus on from the light that sample hole 61 casts out again, to prevent its diffusion.

Curved and revolvable reflection seat 8 is installed in

In the inclined-plane of shell seat short slot 11, be shaped on the corresponding some reflecting optics 81 of light beam that penetrate with opposite side projection lens 5 on the cambered surface of reflection seat 8.Reflecting optics 81 also can have been adopted different color, and it can be reflected the light beam that projection lens 7 penetrates.Because style dish 6 and reflection seat 8 all can be rotated by driven by motor, thus its last light beam that penetrates color part in riotous profusion and fast changing.

Circuits System of the present utility model all is a known technology.

During use, open light source 4, the light that then projects is together with the mixing light that reflects through speculum 3, after light lens 5 focusing are light beam, are projected to different shape and arrive at projection lens 7 via sample hole 61 again, and then reflect via reflecting optics 81, the light of various difformities, different color.

The utility model advantage is can strengthen illumination at it, has prevented the light diffusion, and projection distance is far away, can form the light beam of various difformities, different color, has shadow and changes multicoloured effect.
