摘要
目前城市中多而杂的景观灯,使得城市景观杂乱浮华,导致光污染的产生。针对这一现象,同时考虑到现代人回归自然的审美意识和情趣,在半导体照明(LED)球泡灯的基础上,提出了一种基于仿生学原理的照明方式。通过对萤火虫发光的研究,提取出萤火虫发光时的特征。针对整个萤火虫群无章可循的发光现象,采用调光信号离散化处理的控制手段,对"萤火虫"群中每只"萤火虫"时变以及非线性的发光进行独立精确控制,从而设计出具有萤火虫发光特征的仿生LED球泡灯,大大提高了LED球泡灯的观赏性及与周围环境的协调性。
At present, much and miscellaneous landscape lights in the city. Makes the urban landscape cluttered and vanity. Even case light pollution. In response to this phenomenon, at the same time, considering the return to natural aesthetic consciousness and interest of modern people. This paper based on light emitting diode （LED） bulb, presents a kind of lighting system based on bionics. Through the study of fireflies light, extracted the characteristics of firefly luminescence. According to the phenomenon of the firefly group haphazard luminescence. Make the dimming signal discretization, accuracy control the time-varying and nonlinear firefly luminescence. Thus completing design the bionic LED bulb which has the characteristics of firefly. Greatly improve the ornamental and coordination of the LED bulb.
