Description
Technical field
The present invention relates to a kind of fluorescer device, espespecially a kind of by a plurality of colour bands region, combine to reach improve light extraction efficiency and photochromic multifarious fluorescer device and applicable light-source system thereof.
Background technology
In recent years, projector equipment miscellaneous, for example projector (Projector) has been widely used in family, school or various business situations, for the signal of video signal that a signal of video signal source is provided, amplifies and is shown in screen.For saving power consumption and reduction means volume, the light-source system of current projector equipment (Illumination System) has been used solid-state light emitting element, for example light emitting diode or laser diode, replace existing high-density air body discharging lamp (HID Lamp) or high-pressure sodium lamp.
The light-source system of projector equipment needs to send ruddiness, green glow, blue light (R, G, the primaries such as B), yet generally speaking the luminescence efficiency of solid-state light emitting element is that the luminescence efficiency of blue light solid-state light emitting element is best, therefore the current practice adopts blue light solid-state light emitting element to coordinate Wavelength converter mostly, so that blue light wavelength is changed, for example coordinate fluorescer colour wheel (Phosphor Wheel) or fluorescer colour table (Phosphor Plate) to inspire versicolor light, replace by this mode that ruddiness solid-state light emitting element or green glow solid-state light emitting element directly send ruddiness or green glow, to promote the luminescence efficiency of light-source system integral body.
Generally speaking, the light-source system of existing projector equipment is broadly divided into two types, the first adopts a plurality of blue light solid-state light emitting elements to coordinate the fluorescer colour wheel of a plurality of single sections, and it two is to adopt single blue light solid-state light emitting element to coordinate the single fluorescer colour wheel with a plurality of sections.Refer to Figure 1A and Figure 1B, the structural representation that it is respectively the structural representation of the existing fluorescer colour wheel with single section and has the existing fluorescer colour wheel of a plurality of sections.As shown in Figure 1A, there is the existing fluorescer colour wheel 10 of single section in single section 101, conventionally corresponding central angle angle is 360 degree, it is the fluorescer colour wheel 10 of whole circle, all be coated with the fluorescer of single kind, and this fluorescer is by more than one fluorescent powder separately (being single powder fluorescer) or mix (i.e. mixed powder fluorescer) and form.Secondly, as the existing fluorescer colour wheel 11 with a plurality of sections of Figure 1B demonstration, more commonly take and there are three or four sections as main, for example the first section 111, the second section 112, the 3rd section 113 and the 4th section 114, and respectively at being coated with respectively red fluorescence agent, green fluorescence agent, blue-fluorescence agent and yellow fluorescence agent etc. on the first section 111, the second section 112, the 3rd section 113 and the 4th section 114, and fluorescer of all kinds also for more than one fluorescent powder separately or mix.
For making the variation of fluorescer colour wheel bright dipping, often applying two or more fluorescent powder mixes and makes and mix powder fluorescer, to adjust bright dipping feature, for example: add red fluorescence powder and make look more inclined to one side warm colour, or to add predominant wavelength be that the phosphor of high brightness of 555 nanometers (Nanometer, nm) is to improve bright dipping lumen value etc.Yet, because various types of fluorescent powder is manufactured voluntarily by manufacturer, its composition is difficult to clearly learn, make the difficulty of hybrid modulation fluorescer relatively high, and its main composition material is different, usually cause cascading (Cascade effect), that is the contiguous high energy of low energy rank fluorescent powder (long wavelength's fluorescent material) meeting absorption rank fluorescent powder, and then cause whole light extraction efficiency to reduce.For example, the fluorescer that the yellow fluorescent powder that industry is common and red fluorescence powder are mixed, because gold-tinted part is absorbed by red fluorescence powder in the range section of wavelength 510 nanometer to 580 nanometers, and make total bright dipping frequency spectrum area (going out luminous energy) lower than the frequency spectrum area theoretical value approximately 14% of yellow fluorescent powder and red fluorescence powder mixing.Therefore, by prior art means, carry out the mixing of fluorescent powder, all can cannot reach the theoretical numerical value of expection because cascading causes light extraction efficiency, not only there is the not good problem of luminescence efficiency, more can cause color saturation deficiency or color offset phenomenon, and then the color representation that makes light-source system cannot meet the standard colour gamut of industrial formulation, as hd-tv (High Definition Television, HDTV) Rec.709 standard colour gamut, be the BT.709 of radio communication department of International Telecommunications Union (ITU) suggestion (ITU-R Recommendation BT.709, or title Rec.709).
