Abstract
The utility model provides a reflective large-screen holographical color projection lighting apparatus, which is based on the principle that a holographical grating can split a white light diffraction into a plurality of color light beams. The utility model is characterized in that a plurality of diffraction real image spots with different shapes can be generated just by using the reflection convergent light from a reflector. The utility model has the advantages of compact size, high color light brightness, beautiful appearance of color light spots and wide application prospect.
Description
Technical field
The utility model belongs to field of photoelectric technology, and it refers in particular to the tool that shines that utilizes the making of holographic grating sheet.
Background technology
Known from institute, along with the development of photoelectric technology, existing people utilizes quadrature holographic grating sheet to make light fixture, obtains colored light efficiency.As: name is called " with the glory light fixture of holographic raster grating " its patent No.: ZL85104065, the principle of this lamp is with quadrature holographic grating sheet, be placed between observer and the light source and (see accompanying drawing 1), when allowing the observer see through quadrature holographic grating sheet to go to see light source, can see a plurality of colored virtual image of light source.This technology majority is to make pendent lamp or palace lantern to view and admire for the people, and can not project the real image hot spot on screen; Name is called " large-sized solor projecting lamp ", the patent No.: ZL87293547, and this lamp passes through the holographic grating sheet with a branch of quasi-parallel light beam with collimated, makes it diffraction and goes out a plurality of real image hot spots (seeing accompanying drawing 2).The weak point of this lamp is owing to adopted the collimated method, make that the appearance and size of lamp is huge, and the efficiency of light energy utilization is low, thereby hot spot brightness is low, does not reach practical requirement; Name is called " light holographic colony pattern effect lamp " patent No.: ZL9524259, this lamp be diffracted at holographic grating (reality) as the basis on increased pattern matrix and colour filter (seeing accompanying drawing 3), make more horn of plenty of the color of hot spot and image.But this lamp remains and utilizes the transmission-type collimated light beam, cause its efficiency of light energy utilization low, and its lamp body is huge, and colored hot spot brightness is low, does not reach practical requirement.
Technical scheme
It is holographic colored according to tool that the purpose of this utility model provides a kind of efficiency of light energy utilization height, volume is little, glory brightness is high.
For achieving the above object, the utility model is only to utilize the primary event converging light of reflective mirror to pass the holographic grating sheet, just can form several difform diffraction (real image) hot spot.Promptly place electric light source, place a slice diameter holographic grating sheet identical or more bigger, they are fixed on the shell of lamp just constitute the utility model (as shown in Figure 4) with the collecting lens bore in the place ahead of light source in the place ahead of a reflective collecting lens.
The utility model is to utilize the holographic grating sheet that the beam split of a branch of white light diffraction is made for the principle of multi beam glory, be characterized in utilizing the primary event of reflective mirror to assemble, light is not because the utility model adopts lens, make the utility model compare with traditional holographic colored projecting lamp, have the following advantages: improved the efficiency of light energy utilization greatly, increased colored hot spot brightness, the structure of light fixture is simpler, thereby dwindle the size of light fixture, make this kind projecting light reach the requirement of practicability.
Accompanying drawing and description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the glory fitting structure schematic diagram with holographic raster grating.
Wherein, the 1st, light source, the 3rd, holographic grating sheet;
Fig. 2 is the structural representation of large-sized solor projecting lamp.
Wherein, the 1st, light source, the 2nd, convergent lens, the 3rd, holographic grating sheet;
Fig. 3 is the structural representation of the holographic colony of light pattern effect lamp.
Wherein, the 1st, light source, the 2nd, convergent lens, the 3rd, holographic grating sheet;
Fig. 4 is an example structure schematic diagram of the present utility model.
The specific embodiment
Wherein, the 1st, light source, the 3rd, holographic grating sheet, the 4th, reflective collecting lens, the 5th, shell.
Be example with single photograph tool below, its structure is as shown in Figure 4: electric light source 1 is placed in the place ahead at a reflective collecting lens 4, place a slice diameter and the identical or more bigger holographic grating sheet 3 of collecting lens 4 bores in the place ahead of light source 1, they are fixed on just to constitute the utility model on the shell 5 of lamp single according to tool.
If the holographic grating sheet among the top embodiment is rotatable, then project the rotary color hot spot according to tool.
The utility model also can obtain the combination of the colored hot spot of various ways by a plurality of single combinations according to tool.
Because the utility model is little according to the volume of tool, glory brightness high and colored hot spot flower shape is attractive in appearance, has great application prospect.How to be used for the glory illumination of stage, building outer wall, shopper window and family etc.
Claims (1)
