摘要

LED照明因其具有效率高、寿命长、无汞等优点而成为当今照明技术的主流。LED灯仍然会以热量的形式产生一些过量的热能。目前的工作描述的应用和有效利用这种多余的能量，以获得额外的先进功能的灯-使用它的执行器操作。研究了几种类型的热力致动器。探讨了利用LED灯产生的热能的可能性和可行性。此外，还考虑了使用电控热机械致动器来定位和聚焦LED灯产生的光束的可能性。构造了基于形状记忆和双金属作动器的原型装置并进行了测试。

Thermomechanical Actuators for Light Flux Regulation of LED Light Sources

LED lighting nowadays has become the main lighting technology because of better performance: high efficiency, long lifespan, mercury free etc. LED lamps still produce some amount of excessive thermal energy in the form of heat. Present work describes the application and effective use of this excessive energy to obtain additional advanced functionality of the lamp – use it for actuator operation. Several types of thermomechanical actuators are investigated. The possibility and feasibility of utilization of the heat energy produced by LED lamps are investigated. Also, the possibility to use electrically controlled thermomechanical actuators for positioning and focusing of light beam produced by the LED lamp is considered. The prototype devices based on Shape Memory and Bimetal actuators are constructed and tested.
