Description

一种色轮组件及投影装置 技术领域
本实用新型属于投影技术领域,具体涉及一种色轮组件及投影装置。
背景技术
现有的一些投影装置,采用激光光源产生的激光激发荧光色轮的技术来产生色彩光序列。而该类产品随着光源输出光功率的提高,色轮上的热功耗也随之上升。若色轮散热问题不能得到很好的解决,会极大降低荧光粉受激发光激发的效率,甚至导致色轮本身的损坏。
色轮,是研究颜色相加混合的一种实验仪器。色轮包括一个变速马达,转速约每分钟300~5000转。马达的中心轴装着一个画有360°刻度的圆盘。不同颜色的纸盘互相交叉固定在圆盘上。当马达旋转时,不同的颜色连续刺激视觉器官,即产生相加混合的效果。
色轮及马达轴在封闭腔体内,与外部冷空气进行热量交换的能力较差。色轮在正常工作时,马达高速转动,光束打在色轮上,色轮产生热量,这些热量导致封闭腔体内的温度会持续升高,高温会导致色轮轴及马达寿命降低。随着对产品可靠性的要求越来越高,改善色轮结构,需要降低色轮轴的温度。
技术问题
图1、图2为现有技术中色轮组件的常用结构。该色轮组件包括第一色轮盘101',第一马达102'以及第一色轮轴103'。光束打到第一色轮盘101'上,部分光转化成热量,热量在密闭的空间内越积越多,导致第一色轮轴103'温度越来越高。现有的色轮技术,只能通过加大色轮腔体增加散热面积,或者是增加内循环风扇,降低色轮轴温度。但由于产品外观尺寸受到限制,色轮轴温度过高已经成为高亮度高寿命色轮产品的瓶颈问题。
技术解决方案
本实用新型提出了一种色轮组件及投影装置,能够在不影响色轮正常工作的前提下,在密闭的空间内通过改变色轮结构隔开色轮轴心,降低色轮轴的温度,达到提高产品效率和寿命的目的。
本实用新型提出的色轮组件包括:
色轮盘,用于接收光束;
色轮轴,所述色轮轴垂直装配在所述色轮盘的中心位置,所述色轮轴的一端与所述色轮盘固定连接;
马达,用于驱动所述色轮盘及所述色轮轴,所述色轮轴套设在所述马达上;
隔热层,所述隔热层套设所述色轮轴的表面。
如上所述的色轮组件,其中,所述隔热层与所述色轮轴相焊接。
如上所述的色轮组件,其中,所述隔热层覆盖所述色轮轴的外周壁。
如上所述的色轮组件,其中,所述隔热层覆盖所述色轮轴的与所述色轮盘固定连接的一端相对的另一端的端面。
如上所述的色轮组件,其中,所述隔热层的径向厚度为1mm。
如上所述的色轮组件,其中,所述隔热层与所述色轮盘相贴合,并焊接在所述色轮盘。
本实用新型还提出一种投影装置,其中,所述投影装置包括如上任一一项所述的色轮组件。
有益效果
通过采用上述的色轮组件及投影装置,利用所述隔热层将所述色轮轴覆盖,将所述色轮轴与所述色轮盘产生的热量完全隔离开来,防止所述色轮盘在工作中产生的热量传递给所述色轮轴,可以有效地降低色轮轴的温度,避免了造成色轮轴温度的升高,达到了延长色轮轴使用寿命的目的。

本发明的最佳实施方式
下面结合附图详细说明本实用新型的具体实施方式。
在此记载的具体实施方式/实施例为本实用新型的特定的具体实施方式,用于说明本实用新型的构思,均是解释性和示例性的,不应解释为对本实用新型实施方式及本实用新型范围的限制。除在此记载的实施例外,本领域技术人员还能够基于本申请权利要求书和说明书所公开的内容采用显而易见的其它技术方案,这些技术方案包括采用对在此记载的实施例的做出任何显而易见的替换和修改的技术方案,都在本实用新型的保护范围之内。
图3为本实用新型一种色轮组件及投影装置的色轮组件结构示意图。如图3所示,所述色轮组件包括色轮盘101、马达102、色轮轴103以及隔热层104。
如图3所示,色轮盘101为圆盘状结构,用于接收光束。色轮盘101的表面具有荧光区。当色轮盘101正常工作旋转时,光束照射在所述荧光区,会产生不同的视觉效果。同时,光线也会产生一部分的热量。所述色轮轴103垂直装配在所述色轮盘101的中心位置。所述色轮轴103的一端与所述色轮盘101固定连接。所述色轮轴103的中心设有通孔,所述马达102置于所述色轮轴103的通孔内。所述马达102用于驱动所述色轮盘101及色轮轴103。所述色轮轴103套设所述马达102表面。通过马达102驱动色轮盘101及色轮轴103共同旋转。光束照射在旋转的色轮盘101的荧光区上,使人眼接收到不同的视觉效果。本实用新型所述的色轮组件还包括隔热层104。所述隔热层104套设所述色轮轴103的表面。用于控制色轮轴103的表面温度,提高色轮组件的使用寿命。
色轮盘101与马达102在密闭的空间内,与外部冷空气进行热量交换的能力较小。色轮盘101正常工作旋转时,光束照射在色轮盘101荧光区产生不同视觉效果的同时,一部分光能转换成热能。这些热量在密闭的空间内越积越多,会导致色轮盘101的温度升高,进而导致色轮轴103的温度逐渐升高。但色轮轴103的温度升高后,会影响整个组件的工作。因此,需要降低色轮轴103的温度,以确保色轮组件的正常稳定工作。为了控制色轮轴103的温度升高,本实用新型的色轮组件特别设置了隔热层104。图4为本实用新型一种色轮组件及投影装置中的色轮组件的轴侧图。如图4所示,隔热层104套设于所述色轮轴103上。所述隔热层104的一端与所述色轮盘101端面相贴合。
进一步的,所述隔热层104与所述色轮轴103相焊接。
通过焊接的方式,将隔热层104固定于色轮轴103的表面。防止色轮盘101工作时产生的热量传递给色轮轴103。但也可以通过其他固定连接方式将它们两者装配到一起,具体情况视实际情况而定。
进一步的,隔热层104覆盖所述色轮轴103的外周壁。
为了达到更好的隔热效果,可以将色轮轴103的轴向外表面与热量全部隔开。比如,可以将所述隔热层104完全覆盖在色轮轴103的外表面。隔热层104的轴向高度与所述色轮轴103的轴向高度一致或前者稍大到遮住后者。
进一步的,所述隔热层104覆盖所述色轮轴103的与所述色轮盘101固定连接的一端相对的另一端的端面。
隔热层104覆盖所述色轮轴103的外周壁仅保证了色轮轴103的轴向方向达到隔热效果,但色轮轴103的端面仍暴露于外界中。这样,有一小部分热量会从色轮轴103的端面传至色轮轴103,对色轮轴103造成升温影响。因此,为了更好的达到色轮轴103的整体隔热效果,还可以将色轮轴103完全套设于隔热层104内部,使色轮轴103的外表面完全处于隔热层104内部。将隔热层104延伸至色轮轴103的上端面,将色轮轴103完全包裹在隔热层104内部。使色轮轴103与色轮盘101产生的热量隔离开。
进一步的,隔热层104采用的材质耐高温、密度小、且导热系数低。通过采用隔热层104,将色轮盘101上由光所产生的热量与色轮轴103隔开。如此,色轮盘101表面产生的热量就不会对色轮轴103造成升温影响。因此,可以提高色轮轴103的使用寿命和工作稳定性,进一步提高工作效率。
进一步的,为了达到更好的隔热效果,建议将所述隔热层104的厚度设定为1mm。
进一步的,隔热层104与所述色轮盘101端面相贴合,并焊接在所述色轮盘101。
为了固定隔热层104,防止色轮组件在旋转过程中发生隔热层104的偏离问题,将隔热层104焊接在所述色轮盘101上。当然,也可以采取任何其他的固定连接方式,视具体情况而定。
本实用新型还提出了一种包括上述色轮组件的投影装置。
通过使用该投影装置,能够在不影响色轮正常工作的前提下,在密闭的空间内通过改变色轮结构隔开色轮轴心,降低色轮轴的温度,达到提高产品效率和寿命的目的。
最后需要说明的是,上述披露的各技术特征并不限于已披露的内容,本领域技术人员还可根据实用新型目的进行各技术特征本身的改动或修改各技术特征之间的组合,以实现本实用新型之目的,但这样的改动后修改都应该属于本实用新型的范围。
