Description
本发明涉及照明、显示技术领域,特别地,涉及一种光源装置及显示设备。The present invention relates to the field of illumination and display technologies, and in particular, to a light source device and a display device.
目前,在显示(如投影领域)以及照明领域都开始越来越广泛的应用激光光源,由于具有能量密度高,光学扩展量小的优势,在高亮度光源领域,激光光源已经逐渐取代灯泡和LED光源。At present, laser light sources are becoming more and more widely used in display (such as projection field) and illumination. Due to the high energy density and small optical expansion, laser light sources have gradually replaced bulbs and LEDs in the field of high-brightness light sources. light source.
在当前的投影显示技术中,利用激光光源+荧光轮(色轮)构成RGB三原色光源的方案被广泛的采用。然而,激光激发设置在旋转的色轮上的荧光材料来产生荧光时,荧光材料一方面受激产生荧光,另一方面也会产生一定的损耗功率,这种损耗功率会导致荧光材料的升温。荧光材料的转换效率会随着温度的升高而降低,因此,这种方案的散热问题需要被考虑,此外,由于荧光粉产生的荧光可能颜色不足从而难以达到目前的色域标准,需进一步考虑设置与色轮区段对应的修色轮片来改善荧光颜色,然而修色轮片与色轮的同步控制也是一个难题。如何兼顾色轮散热及其同步控制是现有激光光源+色轮的光源结构设计的一个重要课题。In the current projection display technology, a scheme of RGB three primary color light sources using a laser light source + a fluorescent wheel (color wheel) is widely used. However, when the laser excites the fluorescent material disposed on the rotating color wheel to generate fluorescence, the fluorescent material is stimulated to generate fluorescence on the one hand, and a certain power loss is generated on the other hand, and the power loss causes the temperature of the fluorescent material to rise. The conversion efficiency of fluorescent materials decreases with increasing temperature. Therefore, the heat dissipation problem of this solution needs to be considered. In addition, since the fluorescence generated by the phosphor may be insufficient in color, it is difficult to achieve the current color gamut standard, and further consideration is needed. The color correction wheel corresponding to the color wheel section is set to improve the fluorescent color, but the synchronous control of the color wheel and the color wheel is also a problem. How to balance the color wheel heat dissipation and its synchronous control is an important topic in the design of the light source structure of the existing laser light source + color wheel.

如背景技术所述,现有激光+荧光光源中一般具有荧光轮(色轮)和修色片轮,前者用于接收激光产生荧光,后者用于对荧光进行滤波,使其颜色满足现有的色域标准,一般这两种装置在光源中是区分开来 的。As described in the background art, the conventional laser + fluorescent light source generally has a fluorescent wheel (color wheel) for receiving fluorescence and a color correction wheel, and the latter is used for filtering fluorescence to make the color satisfy the existing one. The color gamut standard, generally the two devices are distinguished in the light source.
对于荧光轮的散热问题,一般需要通过散热装置维持荧光材料在一个稳定的工作温度。现有技术中,会通过在色轮的一个表面或是其它区域进行设置诸如鳍片等散热结构,但随着投影装置亮度的进一步提升,散热能力的提升需要增大色轮的尺寸,因为这样提供了更大的面积用于散热,而这样会导致光源以及投影***的整体尺寸增大。基于上述散热及尺寸的问题,可以考虑通过设置两个小型的色轮装置,分别用于激发不同颜色的荧光,以实现热量的平均。For the heat dissipation problem of the fluorescent wheel, it is generally required to maintain the fluorescent material at a stable operating temperature by means of a heat sink. In the prior art, a heat dissipation structure such as a fin is disposed on one surface of the color wheel or other areas, but as the brightness of the projection device is further improved, the heat dissipation capability needs to be increased to increase the size of the color wheel. A larger area is provided for heat dissipation, which results in an increase in the overall size of the light source as well as the projection system. Based on the above problems of heat dissipation and size, it is conceivable to provide two small color wheel devices for exciting different colors of fluorescence to achieve average heat.
进一步地,对于荧光粉产生的荧光颜色不足以达到目前的色域标准的问题,可以考虑设置修色装置来改善荧光颜色。具体地,可以在光源装置的出口设置修色片来作为修色装置,特别是对于单片空间光调制器的***,可以设置一个与荧光色轮独立的分段的修色片轮,每一段修色片分别对应色轮相应的荧光段,用于对荧光进行滤波,使光源装置发出的光源光颜色满足现有的色域标准。Further, for the problem that the fluorescent color produced by the phosphor is insufficient to meet the current color gamut standard, it is conceivable to provide a color correction device to improve the fluorescent color. Specifically, a color correction sheet may be disposed at an exit of the light source device as a color correction device, and particularly for a system of a single spatial light modulator, a segmented color correction wheel independent of the fluorescent color wheel may be disposed, each segment The color correction patches respectively correspond to the corresponding fluorescent segments of the color wheel, and are used for filtering the fluorescence so that the color of the light source emitted by the light source device satisfies the existing color gamut standard.
具体来说,请参阅图1,图1是一种可用于单片空间光调制器的激光荧光光源的光路示意图。在这种结构中,荧光从色轮上产生后,经过透镜***组收集,然后被透蓝反黄的分色片反射进入方棒,传导进入光机(未示出)。在分色片和方棒之间,设置了修色片轮,来对荧光的颜色进行改善,但是这种方案的色轮产生的热量较高,存在一定的散热困难。Specifically, please refer to FIG. 1. FIG. 1 is a schematic diagram of an optical path of a laser fluorescent light source that can be used in a monolithic spatial light modulator. In this configuration, after the fluorescence is generated from the color wheel, it is collected by the lens system group, and then reflected by the blue-and-yellow color separation sheet into the square rod and conducted into the optical machine (not shown). Between the color separation sheet and the square rod, a color correction wheel is provided to improve the color of the fluorescent light, but the color wheel generated by the solution has a high heat and has a certain heat dissipation difficulty.
进一步地,请参阅图2,图2为另一种采用激发光源+双色轮发出RGB(红绿蓝)三色光的光源方案示意图,在这种方案中,采用了两个小型的色轮(如图2所示的色轮1及色轮2)来分摊激发荧光产生的热量,但是进一步加上修色的装置(如修色轮片)后,需要对三个轮子进行同步的控制,其控制难度较高。Further, please refer to FIG. 2. FIG. 2 is a schematic diagram of another light source scheme for emitting RGB (red, green, and blue) three-color light by using an excitation light source and a two-color wheel. In this scheme, two small color wheels are used (eg, The color wheel 1 and the color wheel 2) shown in FIG. 2 share the heat generated by the excitation fluorescence, but after further adding the color correction device (such as the color wheel), it is necessary to control the three wheels synchronously, and the control thereof is controlled. It is more difficult.
针对以上问题,本发明进一步提出一种可改善色轮散热及同步控制的问题的光源装置。请参阅图3,图3是本发明第一实施方式的光源装置100的结构示意图。所述光源装置100包括激发光源101、位 于所述激发光源101发出的激发光的光路上的依序设置的两个色轮106与107、第一修色片106-2、分光片104、引导元件109与110、合光元件111、中继透镜***102、匀光装置103、透镜***105、108。In view of the above problems, the present invention further proposes a light source device which can improve the problem of color wheel heat dissipation and synchronous control. Please refer to FIG. 3. FIG. 3 is a schematic structural diagram of a light source device 100 according to a first embodiment of the present invention.
