一种聚光灯中透镜的伸缩结构
本技术涉及聚光灯
,具体来说是一种成本低,调节方便,自动化高的聚光灯中透镜的伸缩结构。
技术介绍
目前聚光灯有两种,一种是传统光源的,一种是LED新光源的。传统的聚光灯耗电量大,温度高;LED新光源的聚光灯具有能耗低,颜色选择多体积小等优势,是现在发展的趋势。但是现在的聚光灯中透镜的伸缩结构都是采用滑轨结构或者是螺杆结构,滑轨结构具有调节快的优点,但是容易使透镜歪掉导致误差大,而且容易漏光,螺杆结构具有调节精确的优点,但是调节速度慢,容易积尘卡杆难以转动,拆装维护困难。
技术实现思路
本技术的目的在于提供一种机构紧凑,调节方便快捷,自动化高的聚光灯中透镜的伸缩结构。为了克服上述现有技术中的缺陷本技术采用如下技术方案:一种聚光灯中透镜的伸缩结构,包括底座和透镜支架,位于底座与透镜支架之间的伸缩机构;所述伸缩机构设有齿转盘,若干行星轮和连杆,齿转盘与行星轮连接,透镜支架和齿转盘分别与连杆连接,齿转盘分为内齿转盘和外齿转盘,行星轮位于内齿转盘和外齿转盘之间并与它们齿合;所述连杆两端设有关节轴承,所述内齿转盘和外齿转盘上都设有关节轴承连接座,关节轴承与关节轴承连接座连接。进一步地,所述内齿转盘和外齿转盘上的齿设置为连续一段有齿,然后一段没有齿。进一步地,所述底座上设有散热器,散热器位于底座最底部。进一步地,所述底座上设有传动轴和驱动电机,驱动电机位于散热器上并与传动轴连接,传动轴与行星轮连接。进一步地,所述与内齿转盘和外齿转盘的连杆交叉布置。进一步地,所述透镜支架上设有连杆固定头,连杆固定头通过关节轴承与连杆连接。进一步地,所述内齿转盘设 ...
