用于室内照明的节能环保型智能LED照明系统设计

摘要

针对目前严峻的能源短缺问题,为有效节约室内照明消耗的电能,提出一种结合太阳能和LED技术的照明系统.当环境光能较强时,太阳能电池既向照明系统供电同时为内部储能蓄电池充电；当环境光照较弱时,由蓄电池为照明系统供电；系统兼具USB接口,通过该接口也能对系统内电池充电,以应对长时间光照差的气候.系统具有的自动调光功能,能保持室内工作面光照度稳定,为长久伏案的工作者提供最佳的照明环境.系统具有的自动调光功能和太阳能充电功能,从两个方面降低了电能的消耗.%Aiming at the severe problem of energy shortage nowadays, a illumination system with the combination of solar energy and LED source in order to reduce consumption of indoor lighting is put forward. In condition of large amount of ambient light, the solar cells can supply power for both battery charging and system operation; in condition of little ambient light, the system can be charged by the battery directly. Besides, this system has USB interface through which we can charge the battery in case of long-term low light intensity. This system can realize automatic illumination adjustment and keep the stable illumination in working platform, thus, provide the best luminous environment for long-term white collar workers. Electric power will be largely saved with the automatic illumination adjustment and solar energy charging.
