论继电器带容性负载有粘连——继电器控制LED灯具的探讨

Discussion on Adhesion of Relay with Capacitive Load

智能灯光场景绚烂多彩、赏心悦目呈现在大家眼前,控制方式都是通过弱电控制强电(强电灯具或其他设备)。由于灯具有鸽丝灯、钠灯、疝气灯、高压卤素灯及现流行的LED灯具,它们的工作原理千差万别,对灯控设备的要求也就不同,在设计灯控系统中,就要考虑能够兼容各类灯具的使用,便于用户采购配套灯具。对于鹄丝灯、钠灯、疝气灯、高压卤素灯配套的灯控系统己经成熟,而新型的LED灯具,由于具备节能50%以上、寿命长达40年的明显优势,现被广大用户釆用。但在使用中,会批量或概率性出现继电器粘连现象,使之成为灯控系统研究的新方向。

Smart lighting scenes are gorgeous and colorful, Enjoy the eyes, The control mode is to control the strong current through the weak current (strong current lamps or other equipment). Because the lamp has tungsten filament lamp, sodium lamp, hernia lamp, high pressure halogen lamp and popular LED lamp, their working principle is very different. Requirements for lighting control equipment are also different. In the design of lighting control system, it is necessary to consider compatibility with the use of various types of lamps and lanterns, so as to facilitate the purchase of matching lamps and lanterns by users. For tungsten filament lamp, sodium lamp, hernia lamp, high-pressure halogen lamp matchi ng lamp control system has matured, and new LED lamps and lanterns. Because of the obvious advantages of energy saving of more than 50% and long life of 10 years, it is now adopted by the majority of users. In use, relay adhesion will occur in batches or probability, making it a new direction of the research of light control system.
