Description
Technical field
The utility model relates to lighting field, particularly relates to a kind of light-source system and optical projection system.
Background technology
In the light supply apparatus of stage lighting, normal by R (red, ruddiness), G (green, green glow), B (blue, blue light) three-primary color LED (Light Emitting Diode, light emitting diode) light that produces closes light, wherein realizes that by the drive current of controlling respectively this three-primary color LED the proportioning of different colours is with synthetic different color.Because the light that these three kinds of primary-color LEDs send covers narrower spectral range, in general so narrow spectrum light have higher excitation, makes it seem more bright-coloured than natural color, relatively satisfies the stage performance requirement more bright-coloured to color.
As shown in Figure 1, Fig. 1 is the normal light-source system that adopts in the prior art.The light that each LED in green light LED array 101, red-light LED array 103 and the blue-ray LED array 105 sends synthesizes light beams by cruciform dichroic sheet group 107 behind the collimation lens collimation, and outgoing to fly's-eye lens to 109, after fly's-eye lens is to 109 even light, be transmitted on the screen 113 by projecting lens 111.But when adopting these three kinds of primary lights to come synthesize white light, because the normalization spectrum of these three kinds of primary lights is discontinuous, even continuously, very low at the energy of the spectrum of the intersection of the wavelength coverage of the wavelength coverage of the intersection of the wavelength coverage of the wavelength coverage of blue light and green glow, green glow and ruddiness.As shown in Figure 2, Fig. 2 is the normalization spectrum of the light of three kinds of primary-color LEDs generations of red, green, blue.The normalization spectral coverage of this three-primary color LED is limited, and the spectrum poor continuity is compared with the sunshine spectrum 201 under the identical colour temperature and to be greatly differed from each other, and this causes the colour rendering index of light source very low.Colour rendering index refers to that white light shows the ability of the original color of object behind the body surface.The spectrum of white light and the spectrum of sunshine are more approaching, and it shows that index is just higher; And the spectrum of sunshine is the spectrum of a continuously smooth, and spectral range covers whole visible-range.
For solving the poor problem of the colour rendering index that closes light of R, G, B three-primary color LED, existing a kind of method adopts light-source system as shown in Figure 3, the light path of closing light at R, G, B three-primary color LED adds white light LEDs, to form RGBW (White, white light) light source.As shown in Figure 3, the three-beam of red-light LED 301, green light LED 302 and blue-ray LED 303 outputs is respectively from three plane of incidence incidents of cruciform dichroic mirror 305, through the light action that closes of cruciform dichroic mirror 305, the light beams that closes of exporting from cruciform dichroic mirror 305 is white light beam.White light LEDs 304 be looped around green light LED 302 around, and the white light beam of the white light LEDs 304 output periphery that gets around cruciform dichroic mirror 305 is incided on the lens 306 as how much splicer spares.The white light beam of cruciform dichroic mirror 305 outputs of collecting through lens 306 and the white light beam of white light LEDs 304 outputs enter in the dodging device 307 spares light.By the light filling of white light LEDs, to improve the colour rendering index of this light-source system.
But in above light-emitting device, although the RGBW light-source system has remedied the defective of rgb light origin system colour rendering deficiency to a certain extent, overall colour rendering index is not high.Find that through experiment when the colour temperature of light source was 7000K, the colour rendering index of light source was no more than 80.When the colour temperature of light source was 3200K, the colour rendering index that the colour rendering index of RGBW light-source system is compared the rgb light origin system improved not quite, only has about 30 to 40.
This is owing to when reducing the colour temperature of RGBW light-source system, need to reduce the ratio of blue light, and the white light that white light LEDs sends is to be formed by blue light and yellow light mix, therefore needs to reduce the ratio of the light that blue-ray LED and white light LEDs send.But accordingly, also can reduce the ratio of gold-tinted in the light that white light LEDs sends, therefore little to the improvement of the colour rendering index of former rgb light origin system.
