Abstract: Color tunable lighting systems and methods are disclosed. The color tunable lighting systems and methods include user interfaces that allow for the control of color temperature and luminous intensity by a user. The systems and methods provide for flexibility and scalability, where a control module for controlling one or more solid state light source arrays can be programmed during installation for use with specific solid state light source arrays.

Abstract: A driver port that provides selectable output currents based on connections thereto, and a driver including the same, is provided. A plurality of shunt resistors are connected in series between a negative output of a driver and a ground. A driver port having a plurality of connection points is provided, each respective connection point connected to a different connection between two of the plurality of shunt resistors. A load including one or more solid state light sources is capable of being connected between one of the connection points of the driver port and a positive output of the driver.

Abstract: A multi-strike ballast to ignite an electrodeless lamp is disclosed, and includes an inverter circuit, a protection circuit, and a controller. The inverter circuit, upon activation, sends an ignition pulse to the lamp. The inverter circuit shuts down upon receiving a deactivation signal, and activates upon receiving an activation signal, triggering another ignition pulse. The protection circuit senses a change in a voltage associated with the lamp. The sensed changed may indicate that the lamp has not yet ignited or that the lamp is broken. The controller receives the sensed change in voltage and, in response, sends a deactivation signal to the inverter circuit. The controller waits a predetermined time and then sends an activation signal to the inverter circuit. The controller repeats until a change in voltage associated with the lamp is not sensed, or until a predefined number of repeats occur, providing multiple ignition pulses to the lamp.
Abstract translation: 公开了一种点燃无电极灯的多冲击镇流器，包括逆变器电路，保护电路和控制器。 逆变器电路在激活时向灯发出点火脉冲。 逆变器电路在接收到去激活信号时关闭，并在接收到激活信号时激活，触发另一个点火脉冲。 保护电路检测与灯相关的电压的变化。 所感测到的变化可能指示灯还没有被点燃或灯被破坏。 控制器接收感测到的电压变化，作为响应，向逆变器电路发送去激活信号。 控制器等待预定时间，然后将激活信号发送到逆变器电路。 控制器重复，直到没有检测到与灯相关的电压变化，或直到发生预定数量的重复，向灯提供多个点火脉冲。
