Description
Technical field
The present invention relates to a kind of light supply apparatus and application thereof, relate in particular to a kind of solid state light source, adopt the optical projection system and the cluster type lighting of this device.
Background technology
Great power LED Sony ericsson mobile comm abs such as (comprising OLED) is as novel high brightness; the long-life light source has obtained significant progress in applications such as illuminations; the long-life that it has; characteristics such as high colour purity existing just based on arc glow projection light source was short of; but Sony ericsson mobile comm abs such as LED to be applied to optical projection system; just necessarily require to constitute light source be a comparatively desirable spot light; but the illuminator of each LED is a semiconductor chip with certain light-emitting area; be a low profile light source in essence; and because single led chip luminosity is limited; in order to reach enough big luminous flux; usually also need a plurality of led chips are arranged in array; or adopt larger sized LED planar luminous body; when forming the luminous flux multiplication; the also corresponding multiplication of its light source luminescent area; when the light source luminescent area big more; the imaging efficient of its respective projection imaging optical system is just low more; promptly attempt to increase LED quantity and increase by traditional approach the light output flow (luminosity) of light source and make great efforts to be difficult to gather effect, this is the major technique obstacle that solid light sources such as great power LED is applied to optical projection system.
Usually, for non-strict spot light, adopt " optical extend " (Etendue) to show E=π Asin is promptly arranged its degree of approximation to spot light
2θ, wherein E is optical extend (Etendue) value, and A is the surface source luminescence area, and θ is the maximum angle of flare of area source emergent ray, and light-emitting area is more little, and the maximum angle of flare of light is more little, and the E value is more little, gets over points of proximity light source, otherwise then requires far away more from spot light.Under the prior art condition, with comparatively typical 40mil (1mm
2) led chip is example, its Etendue value is about 3.14mm
2* sr, and for a kind of design of typical projection optical system, the coupling Etendue value of its display light chip is about 34.36mm
2* sr, designing requirement according to the Etendue value≤display light chip Etendue value of light source, promptly can only adopt 9 led chips to line up 3 * 3 array, luminous efficiency with led chip is 40 lumens/W, the optical projection system optical efficiency is 15% calculating, then can only obtain the projected light output of 54 lumens at last, such level can only be used " pocket " type projector as general individual and use, and does not reach general family expenses or the commercial affairs light output requirement with projection display equipment (projection arrangement of back projection or front projection mode) needed hundreds of lumen and even several kilolumens far away.Sony ericsson mobile comm abs such as LED to be replaced tradition " arc light " formula projection light source, one of its technological difficulties to be solved, be to make it under the condition that satisfies the desired Etendue value of optical projection system, increase substantially " the product light quantity " of light source, in other words under the prerequisite that does not increase light source output Etendue value, roll up the led chip quantity that to hold in the light source or the light-emitting area of LED planar luminous body, and the light that led chip sent can be derived with sufficiently high efficient.For reaching its purpose, as shown in Figure 1, publication number is to have disclosed a kind of light supply apparatus in the Chinese patent " light supply apparatus and projecting display " of CN1682070A, according to this technical scheme, at first to construct a bar-shaped optical component, an end face of bar-shaped optical component is an exiting surface, the light output Etendue value of this light source is determined by this face area, other surface of bar-shaped optical component is reflecting surface, led chip vertically is arranged on its lateral reflection face along bar-shaped optical component, the led chip issued light is exported from its light output end behind interreflection between the reflecting surface of bar-shaped optical component inside, thereby can unrestrictedly increase the led chip quantity that is arranged at bar-shaped optical component inside by the length of unrestrictedly extending bar-shaped optical component and unrestrictedly improve the light output quantity that obtains from light output end, attempting to reach significantly increases the target that light source produces light quantity under the condition that does not increase light source Etendue value.Yet, in the disclosed technical scheme of this patent, there is serious defective: be arranged at the led chip in the bar-shaped optical component, both provided the source of this light source light output, it is again the light that will be sent obstacle from the inner guiding of bar-shaped optical component light output end, because in the process that the light that led chip sent is derived by the reflecting surface interreflection of rod member inside, in case these light are mapped on the led chip, will be absorbed by led chip, in chip internal interreflection decay, become the heat of chip and lose.Therefore, more led chip is set in rod member inside in order to obtain the output of more light, but the derivation for light is provided with more obstacle simultaneously, the derivation efficient of light is reduced, do not have to realize that the quantity by at the inner LED of increasing of rod member significantly increases the purpose that light source produces light quantity.In addition, as shown in Figure 2, the characteristics of luminescence of led chip satisfies " Lambertian distribution ", because the led chip luminous energy is relevant with its angle of departure, the light that the angle of departure is more little, its emitted energy is big more, the light that the angle of departure is big more, and its emitted energy is more little, in the disclosed technical scheme of above-mentioned patent, the light that the angle of departure is more little, many more on the contrary at the inner order of reflection that will experience of rod member, it is absorbed by led chip and the probability that loses is just big more.Last result is, when in a large number led chip being set in rod member inside in order to seek the output of high light, only have the light of the very little big angle of departure of part of energy more efficiently to be derived from light output end, it is very low that photoconduction goes out efficient, also is difficult to reach and significantly improves the purpose of producing light quantity.
