Abstract
The utility model discloses a large screen color projection lamp. The existing projection lamp uses filters, which only ejects single color light spots. Though the lamp made of raster plates can generate color patterns composed of seven single color lights, the lights can not show color light spots after being project to the screen. The color projection lamp uses a common light source to send out light which crosses through a collimation optical system and then permeates a rotary holographic grating plate. At last, the rotary and vivid seven color light spots can show on the screen.
Description
The utility model belongs to a kind of projection light fixture.
Existing projecting lamp (as searchlight, stage projecting lamp), can only penetrate monochromatic hot spot, that is to say the light fixture that adopts a kind of optical filter to make, can not present the hot spot of two or more colors simultaneously, if will present two or more color hot spots, must be with the combination of the optical filter of a plurality of band different colours, and want to allow the spot size size variation, also need to change the size of used optical filter.For example to obtain the hot spot of giant-screen, diameter as hot spot is 3～5 meters, the equipment of the size of optical filter, 3～5 meters collimations of generation light beams also need to accomplish 3～5 meters so, are unpractical with large-sized like this optical filter with producing the equipment that collimates light beam in fact.Make the large-sized solor projecting lamp by above-mentioned method, the cost cost is improved, complex structure uses inconvenient.
Chinese patent " grating film rainbow glass " (application number 85200328) and " with the rainbow light and the method for making of holographic raster grating " (application number 85104065) have disclosed two kinds of grating ambettis and light fixture and preparation method thereof, but all can not reach the display effect that is incident upon on the giant-screen.
The purpose of this utility model: provide a kind of can produce giant-screen, that have high brightness, the chromatic colour projected spot, light fixture with low cost, easy to use.It can present seven kinds of bright-coloured colors simultaneously on screen.
In order to realize this purpose, invention scheme of the present utility model is: the light that is sent by the light source of a common high brightness, through a collimating optical system, see through a lenticular lenses, will on screen, obtain the hot spot of seven kinds of bright-coloured colors, when lenticular lenses is placed in a suitable position in the light path, when the colorama spot diameter that throws on screen was 3～5 meters, its color effect was excellent.
Collimating optical system of the present utility model is to be made of the bulb of a high brightness, a condenser mirror and a collimation lens, or by the bulb of a high brightness, a condenser mirror, a collimation lens and a convergent lens constitute.
The lenticular lenses that the utility model is used can be the holographic grating sheet, and it is to be supported by three guide wheels, is driven by a friction pulley that is through in the micromotor rotating shaft and is garden Zhou Yundong, and do to come and go mobile on fore-and-aft direction by back up pad.So just on screen, can present diameter transformable, rotatable, movably, the hot spot of bright-coloured seven kinds of colors.Structure of the present utility model as shown in Figure 1.
The utility model has the advantages that:
Simple in structure: light fixture can produce have rotation, the hot spot of variable, the bright-coloured seven kinds of colors of diameter (scope of hot spot 3 meters～5 meters time color effect the best)
Easy to use: only need lamp is connected civil power (exchanging 220 volts), just can produce the hot spot with seven kinds of colors immediately, if the dimensional orientation of this lamp of change, then the colored hot spot of Zhuan Donging just can move around on screen, forms the colored hot spot of a rolling.
Cost is low, and easily processing is fit to produce in batches, and can energy savings.
The utility model can be used for scenery, and shopper window is decorated, the light decoration of dancing party, concert and recreation ground and the light decoration of buildings, and it has effect bright-coloured, luxurious, style.
Below in conjunction with accompanying drawing the utility model is done further to implement to describe:
Fig. 1: this light fixture synoptic diagram.
Wherein (1): light source (2): condenser mirror (3): collimation lens (4): shell
(5): holographic grating chip module (6): spherical after-poppet (7): the fore-stock of band guide wheel
(8): power lead (9) screen
Fig. 2: holographic grating chip module figure
Wherein: (1): guide wheel (2): back up pad (3): holographic grating sheet
(4): friction pulley accompanying drawing 3: the hot spot on the screen
According to shown in Figure 1, be by whole an of shell (4) of making by metal material or plastic material on the shell of this lamp, having guide wheel fore-stock (7) and having spherical after-poppet (6) composition of holographic grating chip module be housed as illumination partly.
In whole shell (4), the incandescent lamp bulb (1) of a points of proximity light source is housed, condenser mirror (2), collimation lens (3) and power supply wiring (8).Shown in accompanying drawing 2, holographic grating sheet (3) is being supported by three guide wheels (1), and by friction pulley (a 4) drive that is through in the micromotor rotating shaft, produce speed rotation (per 1～2 revolutions per second of rotational speed), guide wheel, friction pulley and micromachine all are fixed on the back up pad 2 of a center drilling, and back up pad (2) is by guide rail can always travelling backwards be moving towards front and back.
When power lead (8) is connected 220 volts of civil powers, bulb (1) is lighted, and light process condenser mirror (2) and collimation lens (3) see through holographic grating chip module (5) afterwards, will on the screen of aiming at, present about 3～5 meters an of diameter, rotation, bright-coloured seven-colour-light spot.(but screen curtain, wall or floor)
By shown in Figure 1, the holographic grating chip module is fixed on the fore-stock (7) of a band guide wheel, illumination partly (4) is fixed on the after-poppet (6) of a dribbling shape, if the front end of lamp is made garden Zhou Yundong, then colored hot spot will be on screen move left and right, until returning three-sixth turn, present the colored hot spot of motion this moment at screen all around.
Promptly constitute the utility model according to above-mentioned making---the large-sized solor projecting lamp.
Claims (6)
