Title: (EN) Adaptive dimmer detection and control for LED lamp
(ZH) 用于LED灯的自适应调光器检测和控制
Abstract: front page image
(EN) The invention relates to adaptive dimmer detection and control for LED lamp. An LED lamp is provided in which the output light intensity of the LEDs in the LED lamp is adjusted based on the input voltage to the LED lamp. A dimmer control unit detects a type of dimmer switch during a configuration process. Using the detected dimmer type, the dimmer control unit generates control signals appropriate for the detected dimmer type to provide regulated current to the LEDs and to achieve the desired dimming effect. The LED lamp can be a direct replacement of conventional incandescent lamps in typical wiring configurations found in residential and commercial building lighting applications that use conventional dimmer switches.

本发明涉及用于LED灯的自适应调光器检测和控制。提供一种LED灯,其中基于向该LED灯的输入电压来调节LED灯中的LED的输出光强度。调光器控制单元在配置过程期间检测调光器开关类型。使用检测到的调光器类型,调光器控制单元生成适合于该检测到的调光器类型的控制信号,以向LED提供经调整的电流并且实现所需调光效果。LED灯可以在典型布线配置中直接替换在使用常规调光器开关的住宅和商用建筑物照明应用中出现的常规白炽灯。
