Description
Technical field
The utility model relates to luminescent system, specifically a kind of device that utilizes the small-power photophore to be combined into the high-power light-emitting device.
Background technology
Traditional is to adopt the high-power light-emitting device than the high-power illumination system, as high-power tungsten lamp, large power, electrically arc lamp, high power laser and high-power and high-luminance light emitting diode etc.The manufacturing cost of these high-power light-emitting devices and use cost are all very high, and most short shortcoming of life-span that all exists.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned high-power light-emitting device, design the device that a kind of a plurality of small-power photophore is combined into the high-power light-emitting device, the a plurality of small-power photophores very low cost combine with special optical system, realize the illumination functions identical with the high-power light-emitting device.
According to design provided by the utility model, several small-power photophores of parallel arranged and several concentrators on support, the corresponding concentrator of each small-power photophore, each small-power photophore is parallel with the line of centres of each self-corresponding concentrator with adjacent small-power photophore with the line of centres of corresponding concentrator.
Each concentrator is the concentrator of an output directional light, at the output of concentrator second concentrator is set, and second concentrator is the concentrator that an energy converges to directional light a bit.Output at second concentrator is provided with the 3rd concentrator, and the 3rd concentrator is a concentrator that can form high-power directional light or non-parallel light.
Perhaps, each concentrator is the concentrator of output diverging light or a converging light, at the output of concentrator second concentrator is set, and concentrator is the concentrator that an energy converges to the light of concentrator output a certain size scope.
The front shape of concentrator is rounded, rectangle or other polygons.Several concentrators are separated from each other, or whole.The small-power photophore is the broadband photophore, or narrow wave band photophore, or the laser instrument of single wavelength.
This novel illuminator almost can be used in the occasion that all need high-power illumination, as stage illumination, lighting, building night illumination, field throw light at a distance, night vision device floor light, the illumination of liquid crystal (LCD) projector, laser guidance, laser radar or the like.

The specific embodiment
This device is with the synthetic method in aperture, several small-power photophores 1 together with concentrator 2 parallel arranged.Arrangement mode can be one dimension or two dimension, as shown in Figure 1.Each concentrator can be circular (as Fig. 3), rectangle (as Fig. 4) or other polygons.Concentrator 2 can separate, and as Fig. 1, Fig. 3 and Fig. 4, also can be whole, is called fly's-eye lens, as Fig. 2 and Fig. 5.The light that is penetrated by concentrator 2 can be directional light, also can disperse (as Fig. 7) or convergence.He Cheng high performance luminaire just can be used for scenery is implemented floodlighting like this, for example car light, high light flashlight, stage illumination, lighting lamp, operation luminaire, night vision device floor light etc.If the light that a plurality of small-power photophores 1 send behind concentrator 2, forms directional light, converge to a bit by second concentrator 3 again, can realize floodlighting, as Fig. 6 to small area.This illumination can produce very high temperature in small zone, and irradiated object is cut or processes.If the light that a plurality of small-power photophores 1 send behind concentrator 2, forms disperse or converging light, converge to a certain size scope again by second concentrator 3, can near the focal plane of concentrator 3, realize floodlighting, as Fig. 7 to certain area object.This illuminator can be used as the illumination of equipment such as big multiplying power projecting apparatus and liquid crystal (LCD) projector.If the light that a plurality of small-power photophores 1 send is behind concentrator 2, form directional light, converge to a bit by second concentrator 3 again, and then form high-power directional light or non-parallel light by the 3rd concentrator 4, as Fig. 8, can realize floodlighting, for example night vision device floor light etc. to remote or closer distance.
A plurality of small-power photophores 1 in the utility model can be the broadband photophores, also can be narrow wave band photophores, can also be the laser instruments of single wavelength.By selecting each small-power photophore spectral characteristic and power, can produce the illuminating bundle of various different-colours or different spectral components.When photophore adopts a plurality of identical wavelength low-power laser, can also be used to producing used high-power laser beams such as laser guidance, laser radar.This high-power laser beam can overcome the illumination unevenness phenomenon that single high-power concentrator is caused by interference fringe, realizes collimation evenly laser lighting preferably.
