【摘要】：本论文主要是基于RGB三基色LED照明系统的设计,结合光源的色度学原理与三基色原理,设计出多彩的光源。目前市场上宣传的保护视力LED灯,并没有真正做到保护眼睛的功能,其光源远远达不到自然太阳光下的效果,本文借助积分球的相关数据,对LED进行调光调色,最终得到近似自然光源的效果。同时,针对目前市场上LED灯具在电路检测方面的不足,文章提出了 LED自动检测装置,此装置与LED构成一个整体,用于对电路中出现的短路和局部断路进行实时的监控。由于LED灯具是由二极管阵列排列而成,在LED灯具出现损坏时,自检装置通过检测负载和电流,判断是否需要更换灯具,或者继续使用,此装置从根本上避免了因短路造成的能源损耗,当出现局部断路时,自检装置通过调节自身电阻达到电流均衡的作用,使照明质量得到保障。本文首先对LED及随后发展出现的三基色LED进行简单的介绍,通过光特性的介绍,引出三基色原理,根据光源的色度学原理与三基色原理,讨论通过三基色混出白光源的可能性,再根据现有的三基色LED制作出实物。此设计的硬件电路主要包括微处理器控制电路,LED的恒流驱动等几个部分。同时,为LED灯具增加检测电路,实现实时监控电路的电流,从而有效的避免了 LED灯具因短路造成的资源浪费。
[Abstract]:This thesis is mainly based on the design of RGB trichromatic LED lighting system, combined with the chrominance principle and tricolor principle of the light source, a colorful light source is designed. At present, there is no real function of protecting the eyes of the protective eyesight LED lamp which is advertised in the market, and its light source is far from the effect of natural sunlight. This paper adjusts the LED light and color with the help of the relevant data of the integral ball. Finally, the effect of approximate natural light source is obtained. At the same time, aiming at the deficiency of LED lamps in the market at present, this paper puts forward the LED automatic detection device, which forms a whole with LED, which is used to monitor the short circuit and local broken circuit in real time. Because LED lamps are arranged by diode arrays, when LED lamps are damaged, the self-testing device determines whether the lamps need to be replaced or continue to be used by detecting the load and current. This device fundamentally avoids the energy loss caused by short circuit. When a local circuit break occurs, the self-testing device can achieve the function of current equalization by adjusting its own resistance, so that the lighting quality can be guaranteed. In this paper, we first introduce LED and the trichromatic LED which appeared later. Through the introduction of the light characteristics, the principle of tricolor is introduced. According to the principle of chrominance and tricolor of the light source, the possibility of mixing the white light source with the trichromatic light source is discussed. Then according to the existing three-color LED made out of the object. The hardware circuit of this design mainly includes microprocessor control circuit, LED constant current drive and other parts. At the same time, the detection circuit is added to the LED lamps to realize real-time monitoring of the current of the circuit, thus effectively avoiding the waste of resources caused by the short circuit of LED lamps.
