    • A projection apparatus includes an illumination system, a light valve, a light beam adjusting element, and a light reflective unit. The illumination system is capable of providing an illumination beam. The light valve, the light beam adjusting element, and the light reflective unit are disposed on a transmission path of the illumination beam. The light valve is disposed between the illumination system and the light reflective unit. The light valve has an active surface for being capable of converting the illumination beam into an image beam. The light beam adjusting element is disposed on the transmission path of the illumination beam and between the illumination system and the light valve. The light beam adjusting element includes at least one lens having a first optical axis. The first optical axis and a normal vector of the active surface are not perpendicular to each other.
    • 投影装置包括照明系统,光阀,光束调节元件和光反射单元。 照明系统能够提供照明光束。 光阀,光束调节元件和光反射单元设置在照明光束的传输路径上。 光阀设置在照明系统和光反射单元之间。 光阀具有能够将照明光束转换为图像光束的有源表面。 光束调节元件设置在照明光束的传输路径上,并且在照明系统和光阀之间。 光束调节元件包括具有第一光轴的至少一个透镜。 有源表面的第一光轴和法向量不彼此垂直。

    • A color wheel including a first sheet, a second sheet, a ring filter and a motor is provided. The second sheet is disposed opposite to the first sheet, and has positioning pins. The ring filter is disposed between the first sheet and the second sheet, and has a plurality of positioning holes. The positioning pins are disposed through the positioning holes and connected to the first sheet. The motor includes a turntable and an axis connected to the turntable, and a positioning portion is disposed on the top of the axis. The positioning portion includes at least two locking hooks, and a notch is disposed between the locking hooks. The notch is suitable for accommodating the locking hooks with deformation. Moreover, the first sheet, the second sheet and the ring filter are disposed through the axis and fixed on the turntable. The reliability of the color wheel is better.
    • 提供了包括第一片,第二片,环形过滤器和电动机的色轮。 第二片与第一片相对设置,并具有定位销。 环形过滤器设置在第一片材和第二片材之间,并且具有多个定位孔。 定位销通过定位孔设置并连接到第一片。 马达包括转盘和连接到转台的轴线,定位部分设置在轴的顶部。 定位部分包括至少两个锁定钩,并且凹口设置在锁定钩之间。 该凹口适于容纳变形的锁定钩。 此外,第一片材,第二片材和环形过滤器穿过轴线设置并固定在转台上。 色轮的可靠性更好。
