技术领域 FIELD

[0001] 本发明涉及一种光源装置及其应用,尤其涉及一种固态光源装置、采用该装置的投影系统及集束式照明灯具。 [0001] The present invention relates to a light source apparatus and its application, in particular, relates to a solid-state light source device, using the projection system and the cluster-type lighting device.

背景技术 Background technique

[0002] 大功率LED (包括0LED)等固态发光器件作为新型的高亮度、长寿命光源在照明等应用领域获得了长足的发展,其具有的长寿命、高色纯等特点正是现有基于电弧发光的投影光源所欠缺的,但要将LED等固态发光器件应用于投影系统,就必须要求所构成光源为一个较为理想的点光源,但每一个LED的发光体为一个具有一定发光面积的半导体芯片, 本质上是一个小型面光源,且由于单只LED芯片发光亮度有限,为了达到足够大的发光通量,通常还需要将多个LED芯片排列成阵列,或采用更大尺寸的LED面发光体,在形成发光通量倍增的同时,其光源发光面积也相应倍增,当光源发光面积越大,其相应的投影成像光学系统的成像光效率就越低,即试图通过传统方式增加LED数量来增加光源的光输出通量(发光亮度)努力是难以凑效的,这是将大功率LED等固体光源应用 [0002] powerful LED (including 0LED) and other solid state light emitting device as a new high-brightness, long-life light source obtained considerable development in lighting applications, having a long life, high color purity, etc. It is based on existing emitting projection light source arc lacking in, but want solid state light device such as an LED applied to a projection system, it is necessary to constitute the light source requires that a more ideal point light source, but each of the LED light emitter having a light emitting area of ​​a certain the semiconductor chip is essentially a small area light source, and a single LED chip due to limited light emission luminance, in order to achieve a sufficient luminous flux, usually requires a plurality of LED chips arranged in an array, or the use of larger surface emitting LED body, is formed at the same time doubling the luminous flux, which is a light source emitting a corresponding area is also doubled, when the light emitting area is larger, the lower the efficiency of the projection imaging light corresponding to the imaging optical system, i.e., by attempting to increase the number of LED in a conventional manner to increase the light output flux of the source (emission luminance) of ridiculous effort is difficult, which is a solid light source such as an LED power applications 于投影系统的主要技术障碍。 The main technical obstacle to the projection system.

[0003] 通常,对于非严格点光源,采用“光学扩展量” ^tendue)来表明其对点光源的近似程度,即有E= JiAsin2 θ,其中E为光学扩展量^tendue)值,A为面光源发光面积,θ 为面光源出射光线最大扩散角,发光面积越小,光线最大扩散角越小,E值越小,越接近点光源,反之则离点光源要求越远。 [0003] Generally, for the non-strict point source, the "etendue" ^ tendue) to indicate the degree of approximation of the point light source, that is E = JiAsin2 θ, where E is the etendue ^ tendue) value, A is area plane light source, a surface light source [theta] maximum diffusion angle of emitted light, the light emitting area is smaller, the smaller the maximum diffusion angle of the light, the smaller the value of E, the closer the point source, and vice versa farther away from the point light source requirements. 在现有技术条件下,以较为典型的40mil (lmm2) LED芯片为例,其Vendue值约为3. 14mm2*sr,而对于一种典型的投影光学系统的设计,其显示光芯片的匹配Kendue值约为34. 36mm2*sr,按照光源的Kendue值<显示光芯片Kendue值的设计要求,即只能采用9只LED芯片排成3X3的阵列,以LED芯片的发光效率为40流明/ W,投影系统光效率为15%计算,则最后只能得到M流明的投影光输出,这样的水平只能作为一般的个人应用“袖珍”型投影机所使用,远远达不到一般的家用或商务用投影显示装置(背投影或前投影方式的投影装置)所需要的几百流明乃至几千流明的光输出要求。 Under prior art conditions, in a more typical 40mil (lmm2) LED chip, for example, its value is about Vendue 3. 14mm2 * sr, and for a typical design of a projection optical system, which optical chip display the matching Kendue value of about 34. 36mm2 * sr, according to the value of the light source Kendue <Kendue display design requirement of the optical chip values, i.e., using only nine LED chips arranged in an array of 3X3, luminous efficiency of the LED chip 40 lumens / W, the projection system light efficiency of 15%, only the last obtained output projection light M lumens, such levels can be used as a general personal application "pocket" type projector, far less than the typical home or business light output requires hundreds or thousands of lumens of lumen devices (rear projection or front projection of the projection device) required for projection display. 要将LED等固态发光器件取代传统“弧光”式投影光源,其所要解决的技术难点之一,是要使其在满足投影系统所要求的Vendue值的条件下,大幅度提高光源的“产光量”,或者说在不增大光源输出Vendue值的前提下,大量增加光源中所能容纳的LED芯片数量或LED面发光体的发光面积,并能将LED芯片所发出的光以足够高的效率导出。 To the solid state light emitting device such as an LED to replace the traditional "arc" projection light, one of the technical problems to be solved by it, is allowed to "yield at Vendue light amount value required to meet the projection system, a substantial increase of the light source ", or without increasing the Vendue light source output value, a significant increase in the number of the light emitting area of ​​the LED chip or an LED light source of planar light emitters can be accommodated, and can sufficiently high efficiency of light emitted from the LED chip export. 为达其目的,如图1 所示,公开号为CN1682070A的中国专利“光源装置和投影式显示装置”中披露了一种光源装置,按照该技术方案,首先要构造一个棒状的光学构件,棒状光学构件的一个端面为出光面,该光源的光输出Vendue值由该端面面积所确定,棒状光学构件的其它表面均为反射面,LED芯片沿棒状光学构件纵向设置于其侧反射面上,LED芯片所发的光在棒状光学构件内部的反射面之间反复反射后从其出光端面输出,从而可以通过无限制地延伸棒状光学构件的长度来无限制地增加设置于棒状光学构件内部的LED芯片数量来无限制地提高从出光端面获得的光输出量,试图达到在不增加光源Vendue值的条件下大幅增加光源产光量的目标。 To achieve its purpose, as shown in FIG disclosed Chinese patent No. CN1682070A "light source device and projection-type display apparatus" 1 discloses a light source device according to this aspect, a first rod-shaped configuration of the optical member, the rod-shaped end surface of the optical member is a light emitting surface, the light output of the light source Vendue value is determined by the area of ​​the end surface, the other surface of the optical member are rod-shaped reflective surface, LED chips disposed side thereof along the longitudinal reflecting surface of the rod-shaped optical member, LED chip after emitted light is repeatedly reflected between the reflective surfaces of the optical member from the interior of the rod-shaped light output end face, which can be unlimited increase in the rod-shaped optical member disposed within the rod-shaped extension of the LED chip through the optical member unlimited unlimited number to increase the light output of the light amount obtained from the end face, an attempt to achieve a substantial increase in production amount of light sources without increasing the target value Vendue light conditions. 然而,在该专利所披露的技术方案中存在严重的缺陷:设置于棒状光学构件中的LED芯片,既是提供该光源光输出的源泉,又是将所发出的光从棒状光学构件内部导向出光端面的障碍,因为当LED芯片所发出的光通过棒状构件内部的反射面反复反射导出的过程中,一旦这些光线射到LED芯片上,就会被LED芯片吸收,在芯片内部反复反射衰减,变成芯片的热量而损失掉。 However, there is in the patent disclosed aspect serious drawback: disposed on the rod-shaped optical member of the LED chip, providing both the source of the source light output, but also light the emitted light from the end surface inside the guide bar-shaped optical member obstacles, because when the rod-shaped member through an internal process of the light reflecting surface of the LED chip is emitted repeatedly reflected exported, once the incident light on the LED chip, the LED chip is absorbed, attenuated repeatedly reflected inside the chip, into the chip's heat is lost. 因此,为了获得更多的光输出而在棒状构件内部设置更多的LED芯片, 但同时却为光线的导出而设置了更多的障碍,使光线的导出效率降低,没有实现通过在棒状构件内部增加LED的数量来大幅增加光源产光量的目的。 Therefore, to obtain more light output of the rod-shaped member provided inside more LED chips, but at the same light provided to derive more obstacles to reducing the light extraction efficiency is not achieved by a rod-shaped inner member increasing the number of LED to a substantial increase in the amount of light of the desired product source. 另外,如图2所示,LED芯片的发光特性满足“Lambertian分布”,由于LED芯片发光能量与其发射角有关,发射角越小的光,其发射能量越大,发射角越大的光,其发射能量越小,在上述专利所披露的技术方案中, 发射角越小的光,在棒状构件内部所要经历的反射次数反而越多,其被LED芯片吸收而损失的几率就越大。 Further, as shown in FIG. 2, the light emitting properties of the LED chips satisfies "a Lambertian distribution", since the LED chip emitting angle about its energy, the smaller the light emission angle, the greater the emission energy, the emission angle of light larger, which the smaller the energy emitted, in the technical solution disclosed in the patent, the light emission angle is smaller, the number of reflections inside the rod-shaped member to be experienced but the more chance that it will be absorbed by the LED chip and the greater the loss. 最后的结果是,当为了谋求高光输出而在棒状构件内部大量设置LED芯片时,仅有能量很小的部分大发射角的光线能够被较为有效地从出光端面导出,光导出效率很低,亦难以达到大幅提高产光量的目的。 The final result is that, when a high optical output in order to seek a large number of LED chips disposed in the interior of the rod-shaped member, only a small portion of the light energy of a large emission angle can be more efficiently derived from the light incident surface, light extraction efficiency is very low, also difficult to achieve a substantial increase in the amount of light produced.

[0025] 六面体结构是一个最稳定的结构,并且其出光口几何形状便于与投影系统匹配, 另外,六面体是多面体结构中最方便加工、组装的一种结构。 [0025] hexahedral structure is a most stable structure, and the light outlet geometry which facilitates matching the projection system, in addition, hexahedral polyhedral structure is the most convenient process, a construction assembly.

[0026] 由于大量高密度安装的发光芯片,大功率固态发光组件在工作时会产生高温,为了将发光芯片的PN结温度控制在可以长时间高效率工作的温度范围内,就要对固态发光组件进行有效散热,因此将发光芯片贴装在导热良好的热沉上制作成发光板,并通过半导体制冷器对发光板进行冷却,再通过导热装置将所产生的热量导出。 [0026] Since a large number of the light emitting chip high-density mounting, high-power solid state light assembly will generate heat during operation, the temperature of the PN junction to the light emitting chip can be controlled within a temperature range for a long time to work efficiently, it is necessary for the solid state light cooling components effectively, thus making the light emitting chip mounted on a good heat sink to the heat emitting plate, and cools the refrigerator through the semiconductor light emitting board, and then the heat generated by a heat export means.

[0027] 在多面体光学构件与出光口相对的底面设有棱锥状反射层,该棱锥状反射层可以将经导光棱镜折射或全反射后射到此表面的光线再反射,并以较小的发射角射向出光口, 减小从出光口导出光线的发射角,并减少光线再反射回入光口而造成的光线损失,提高了光效率。 [0027] In the optical member and the bottom surface of the polyhedral pyramid shaped reflector layer provided opposite to the light port, the pyramidal reflective layer may be refracted or totally reflected light incident on this surface and then reflected by the prism light guide, and a small emission angle toward the light outlet, reducing emission angle of light rays derived from the opening, and then reduce the light reflected back into the light loss caused by the optical port, improving the light efficiency.

[0028] 导光棱镜采用条状、非对称楔形导光棱镜,不同方向的折射或反射不同,具有非对称型光能量分布特性,可利用这个特性,使光的主要能量输出方向朝向出光口方向,光线可在多面体内低损耗地导向出光口,从而获得高的光导出效率,并在有限的光源Vendue值的限制下,大幅增加发光板的发光面积,从而获得高的产光量。 [0028] The light guide prism Using a bar, asymmetrical wedge-shaped light guide prism, different refracted or reflected in different directions, with the light energy distribution characteristics of the asymmetric type, can use this feature, the light of the main energy output direction towards the light outlet direction , the light can be guided in the low loss optical interface polyhedron, thereby obtaining a high light extraction efficiency, and a light source within the constraints of limited value Vendue, a substantial increase in luminous area of ​​the plate, so as to obtain a high yield of the light amount.

[0029] 在多面体光学构件的侧面所设置的发光板分别发出红、绿、蓝三基色中不同的基色光,在多面体光学构件内合成,并在出光口输出合成白光。 [0029] In the light emitting plate emits the optical member side surface of the polyhedron are provided red, green, and blue color shade in different groups, synthesized in the polyhedral optical member, and the optical output port synthesized white light. 在每一种基色的发光板所对应的导光棱镜或导光棱镜阵列板的底面,分别设置能透过该种基色光而反射其它基色光的滤光介质膜,由于不同侧面所设置的发光板和对应的滤光介质膜不同,则当发光板所发出的光在多面体光学构件空间内传输而反射或折射进其它侧面的导光棱镜阵列板时,就可被该导光棱镜阵列板底面的不同基色滤光介质膜所反射而得以回收,从而减少光线的逃逸损失,提高光导出效率。 In the bottom surface of each of the primary color light emitting light guide plate corresponding to the light guide prism or prism array plate, each dielectric film filter can be disposed while reflecting other kinds of color light transmitted through the primary light, since the light emitting different sides provided different filter plate and the corresponding dielectric film, when light propagates within the optical member emitting space polyhedral plate is reflected or refracted and emitted into the other side surface of the prism array of the light guide plate, the light guide can be the bottom surface of the prism array plate different color filter film and the dielectric reflector is recovered, thereby reducing the loss of light escape, to improve the light extraction efficiency.

[0030] 在发光板和导光棱镜阵列板的匹配面之间可以留有空气隙,以使六面体光学构件内的部分光线在导光棱镜底面产生全反射,降低光线逃逸损耗,或者在匹配面之间辅以折射率匹配剂,可以防止发光板所发出的光线在匹配面产生全反射,提高光的导入效率。 [0030] The mating surface may be left between the emitting and the light guide plate prism array plate air gap, so that a portion of light within the hexahedral optical member is totally reflected in the light guide prism bottom surface, reducing the loss of light escape, or mating surface supplemented between the index matching agent, it can prevent the light emitted from the light emitting plate is totally reflected in the mating surface, to improve the introduction efficiency of light.

[0031] 在入光口处设有三角折光棱镜,通过三角折光棱镜的反射面反射使得固态发光组件的安装方向与出光口平行,从而可以使固态发光组件处于同一平面(或同一方向),减小了固态发光组件所占的空间位置。 [0031] with a triangular refractive prism light entrance mouth, through the reflective surface triangular refractive prism reflector so that the mounting direction of the solid-state light-emitting element and the parallel optical interface, which can cause the solid state light assembly in the same plane (or in the same direction), Save small spatial position occupied by solid-state lighting components.
