【摘要】 传统电脑灯普遍使用金属卤化物光源,这种光源发光效率低、发热量大且容易损耗。针对这一问题,本文设计了一种以RGB三色激光器为光源的电脑灯。灯具包括电路系统、机械系统和光学系统,采用DMX512协议为控制协议,以单片机为核心构成控制系统。分析了DMX512协议的格式特点。说明了系统各部分的功能,着重介绍了电路系统的软件实现,针对所选用的RGB光源给出了光学混色系统。对照金属卤化物光源,分析了使用激光光源的优势。更多还原

【Abstract】 Metal halide which is widely used in intelligent beams as lamp-house,has low luminous efficacy,heats a lot and easily wears down.Aiming at these problems,this paper designs an intelligent beam using RGB-laser.This intelligent beam consists of electronic system,mechanical system and optical system.It is controlled by the DMX512 protocol.Controlling system is realized by single chip.The data format of DMX512 is introduced.Function of each part of the intelligent beam is analyzed,especially the controlling system and its software.Considering the RGB-laser used,there is an optical system mixing RGB beams.The advantages of the laser lamp-house compared with the traditional ones are analyzed.更多还原
