Description
本实用新型涉及色轮技术领域，更具体地说，涉及一种光源装置及色轮。The utility model relates to the technical field of color wheel, and more particularly to a light source device and a color wheel.
目前，激光荧光粉技术发展迅速，并得到了广泛的应用。激光荧光粉技术，即用激光光束激发荧光粉产生荧光，通常使用蓝激光作为激发光。在可见光范围内，光子的能量会与波长成负相关变化，波长越短，光子能量越大，因此，当用短波长的蓝激光激发荧光粉时，能量较高的蓝激光光子会被荧光粉材料吸收，并释放出能量较低的长波长荧光光子。At present, laser phosphor technology has developed rapidly and has been widely used. Laser phosphor technology, which uses a laser beam to excite phosphors to produce fluorescence, usually using a blue laser as the excitation light. In the visible range, the photon energy will change negatively with the wavelength. The shorter the wavelength, the larger the photon energy. Therefore, when the phosphor is excited by the short-wavelength blue laser, the higher-energy blue laser photon will be phosphor. The material absorbs and releases long-wavelength fluorescent photons with lower energy.
由于散热的需要，通常要将荧光粉及其载体与高速旋转的马达一起做成色轮的形式。在转动的过程中，色轮表面高度的差异会降低对荧光粉的激发效率，以及造成荧光光轴的偏移，对后续的光能利用效率和亮度一致性都会损失。因此，需要一种表面高度一致性较好的光源装置。Due to the need for heat dissipation, the phosphor and its carrier are usually formed in the form of a color wheel together with a motor that rotates at a high speed. During the rotation process, the difference in the height of the color wheel surface reduces the excitation efficiency of the phosphor, and causes the shift of the fluorescence optical axis, which is lost for subsequent light energy utilization efficiency and brightness uniformity. Therefore, there is a need for a light source device having a high surface height consistency.
现有技术中的光源装置如图1所示，激光器211发射激光光束经中继透镜212成像于荧光粉201表面，激发荧光粉产生荧光并以郎伯光的形式反射。荧光粉201及其载体202通过胶水206粘接在色轮基板204的定位槽207中，色轮基板204的定位槽如图2所示。驱动马达205可以带动色轮基板高速旋转。The light source device in the prior art is as shown in FIG. 1. The laser beam 211 emits a laser beam and is imaged on the surface of the phosphor 201 via the relay lens 212, and the phosphor is excited to generate fluorescence and is reflected in the form of light. The phosphor 201 and its carrier 202 are bonded to the positioning groove 207 of the color wheel substrate 204 by the glue 206, and the positioning groove of the color wheel substrate 204 is as shown in FIG. The drive motor 205 can drive the color wheel substrate to rotate at a high speed.
在用胶水206粘接荧光粉载体202与色轮基板204时，由于胶水是液体，具有流动性，胶量的涂抹不均匀以及在装夹的过程中压力不均匀，容易造成荧光粉载体202倾斜，荧光粉表面高度不一致。When the phosphor carrier 202 and the color wheel substrate 204 are bonded by the glue 206, since the glue is liquid, fluidity, uneven application of the glue amount, and uneven pressure during the clamping process, the phosphor carrier 202 is easily inclined. The phosphor surface height is inconsistent.
这样会使色轮在转动时蓝激光在荧光粉表面成的像时而清晰时而模糊，造成激光效率的不一致，并且反射的荧光光轴会向不同方向偏移。最终，会导致照明光的颜色和亮度不均匀。This will make the blue laser light on the surface of the phosphor clear and sometimes blur when the color wheel rotates, resulting in inconsistent laser efficiency, and the reflected fluorescent optical axis will shift in different directions. Eventually, the color and brightness of the illumination light will be uneven.
因此，如何解决现有技术中，荧光粉载体容易倾斜的问题，成为本领域技术人员所要解决的重要技术问题。Therefore, how to solve the problem that the phosphor carrier is easily tilted in the prior art has become an important technical problem to be solved by those skilled in the art.
有鉴于此，本实用新型的目的在于提供一种色轮，其能够避免波长转换部件容易出现倾斜的问题，进而可以保证色轮的照明光的颜色和亮度具有较好的均匀性。In view of the above, an object of the present invention is to provide a color wheel capable of avoiding the problem that the wavelength conversion member is prone to tilt, thereby ensuring better uniformity of color and brightness of the illumination light of the color wheel.
