[0023] 图 3是本发明第三实施方式的色轮组件的示意图。
[0024] 图 4是本发明第四实施方式的色轮组件的示意图。
[0025] 图 5是本发明第五实施方式的色轮组件的示意图。
[0026] 图 6是本发明第六实施方式的色轮组件的示意图。
本发明的实施方式
[0027] 为使本发明的目的、 技术方案和优点更加清楚, 下面将结合附图对本发明实施 方式的色轮组件、 光源装置及投影设备作进一步地描述。
[0028] 第一实施方式
[0029] 请参阅图 1, 图 1为本发明第一实施方式的色轮组件 100的示意图, 色轮组件 100 包括色轮盘 10、 驱动件 (图未示) 及驱动轴 30, 驱动轴 30与色轮盘 10传动连接 , 将色轮盘 10与驱动件连接, 从而驱动件可驱动色轮盘 10转动。 色轮盘 10呈圆 形板状, 其中部幵设有安装孔 101, 驱动轴 30安装于该安装孔 101内。 可以理解 , 驱动轴 30可为驱动件自身的驱动轴, 也可为与驱动件的驱动轴连接的其他驱 动轴。
[0030] 色轮盘 10包括光处理部 11、 多个隔热部 13及连接部 15。 光处理部 11呈环形, 其 包括荧光部 112及滤光部 114, 荧光部 112设于色轮盘 10的外圈, 其表面形成有荧 光粉层, 滤光部 114表面形成有滤光层, 设于荧光部 112内侧, 即滤光部 114的外 侧边缘与荧光部 112的内部边缘连接, 滤光部 114用于对从荧光部 112出射的出射 光进行滤光处理。 隔热部 13用于隔离光处理部 11与驱动轴 30之间的热量传导, 每个隔热部 13大致呈扇形, 其从安装孔 101的边缘延伸至光处理部 11的内侧边缘 , 多个隔热部 13间隔均匀地设置在色轮盘 10的内圈。 连接部 15用于连接光处理 部 11及驱动轴 30, 其包括圆环部 151及肋条部 153, 圆环部 151套设在驱动轴 30上 并与其固定连接; 肋条部 153沿色轮盘 10的径向延伸, 其两端分别连接滤光部 11 4与驱动轴 30, 且位于相邻的两个隔热部 13之间, 两侧分别与两个隔热部 13连接
[0031] 隔热部 13及连接部 15均采用低导热系数的隔热材料制成, 其导热率系数小于或 等于 25W/m*K, 如玻璃、 不锈钢等。 可以理解, 隔热部 13与连接部 15可以采用 相同材料也可采用不同材料, 当采用相同材料吋, 隔热部 13与连接部 15可理解 为同一部件。 优选地, 隔热部 13的导热系数大于连接部 15的导热系数, 且隔热 部 13的表面积相较于连接部 15的更大, 从而更利于散热。
[0032] 由于光处理部 11与驱动轴 30未直接连接, 色轮组件 100工作吋, 连接部 15和 /或 隔热部 13能很大程度阻止热量从光处理部 11向驱动轴 30的传导, 隔离两者的热 量直接传导, 可以有效地阻隔光处理部 11产生的热量传导至驱动轴 30; 而不可 避免地传导至隔热部 13和连接部 15的部分热量, 可在其表面及吋散发, 因此, 采用色轮组件 100吋, 既能抑制驱动轴 30温度的升高, 也可提高色轮组件 100的 散热性能。
[0033] 可以理解, 荧光部 112、 滤光部 114、 隔热部 13与连接部 15之间可以采用粘结、 卡接、 焊接等方式连接或固定。 荧光部 112和 /或滤光部 114还可以包括多个分区 , 以产生多种受激光及对对应的各受激光进行过滤。 可以理解, 隔热部 13的数 量可依实际情况变化, 相应地, 连接部 15的肋条部 153的数量也随之变化。 隔热 部 13也可非均匀地间隔设置, 相应地, 肋条部 153也可非均匀地间隔设置。
[0034] 第二实施方式
[0035] 请参阅图 2, 第二实施方式的色轮组件 200的结构与第一实施方式的色轮组件 10 0的结构大致相同, 其不同在于: 色轮组件 200的光处理部仅包括荧光部 2112, 即该色轮盘 210为荧光轮。
[0036] 可以理解, 光处理部也可以仅包括滤光部, 即色轮盘 210为滤光盘。
[0037] 第三实施方式
[0038] 请参阅图 3, 第三实施方式的色轮组件 300的结构与第一实施方式的色轮组件 10 0的结构大致相同, 其不同在于: 相邻的两个肋条部 3153之间采用镂空结构形成 镂空部 3150, 即省略隔热部, 仅使肋条部 3153连接驱动轴 330与光处理部 311。 采用上述结构吋, 由于光处理部 311与驱动轴 330未直接连接, 肋条部 3153能很 大程度阻止热量从光处理部 311向驱动轴 330的传导, 隔离两者的直接热传导, 从而避免驱动轴 330温度过高。
[0039] 第四实施方式 [0040] 请参阅图 4, 第四实施方式的色轮组件 400的结构与第一实施方式的色轮组件 10 0的结构大致相同, 其不同在于: 连接部 415仅包括多个肋条部 4153, 使肋条部 4 153与驱动轴 430的端部外周直接固定连接, 从而省略圆环部。
[0041] 第五实施方式
[0042] 请参阅图 5, 第五实施方式的色轮组件 500的结构与第四实施方式的色轮组件 40 0的结构大致相同, 其不同在于: 隔热部 513采用部分镂空结构, 在隔热部 513与 驱动轴 530之间设置间隙 5130, 从而一方面可将光处理部 511产生的热量通过隔 热部 513部分地传导出来, 另一方面, 隔热部 513传导出来的热量不易传导至驱 动轴 530上。
[0043] 第六实施方式
[0044] 请参阅图 6, 第六实施方式的色轮组件 600的结构与第一实施方式的色轮组件 10 0的结构大致相同, 其不同在于: 肋条部 6153穿过滤光部 6114而与荧光部 6112直 接连接。
[0045] 本发明的第一至第六实施方式还提供包括上述任一色轮组件 100, 200, 300, 4
00, 500, 600的光源装置及投影设备。
[0046] 在本文中, 术语"包括"、 "包含 "或者其任何其他变体意在涵盖非排他性的包含
