摘要： A driver for a lighting device includes: a lighting driver configured to drive LED(s) of the lighting device in a first mode of operation when a primary power source is available and provided to the lighting driver and to control power output and/or final output current utilizing a backup or other secondary power source during an emergency mode of operation. In example embodiments and implementations, the lighting driver includes a single instance of a LED driver (e.g., only one LED driver circuit) configured to drive LED(s) of the lighting device during both modes of operation.

摘要： LED driver apparatus and methods may include a sensing circuit for adjusting an output based on either a pulse width modulation dimming control or an analog dimming control. An LED driver apparatus and methods may also include a sensor for a parameter such as temperature and for recording such parameter, for example as a function of time. A setting unit for an LED driver apparatus can be used to sense and/or adjust settings in the LED apparatus even when the LED apparatus is not independently powered.

摘要： A network bridge for a lighting system is disclosed. For one example, a lighting system includes an inter-integrated circuit (I2C) cable, a light emitting diode (LED) driver, and wireless module coupled to the LED driver by way of the I2C cable. The LED driver is configured to control one or more LED light sources. The wireless module includes an antenna configured to receive a message according to any number of a plurality of wireless communication protocols. The wireless module is configured to process the message into an I2C data frame and to deliver the I2C data frame to the LED driver via the I2C cable, and the LED driver is configured to control a lighting application or one or more LED light sources based on an I2C data frame. The message can be a wireless communication protocol message such as a ZigBee message, Bluetooth message or WiFi message. The wireless module includes bridge circuitry configured to process the Zigbee message, Bluetooth message or WiFi message into an I2C data frame and to deliver the I2C data frame to the LED driver via the I2C cable using a serial data communication protocol.

摘要： A supplemental lighting system includes a charging circuit having a reference voltage for the charging circuit set through changes to reference resistances, and/or having an output voltage, current or power set through a connector configuration. In one example, a battery storage connector can be used to select a particular resistance for setting the reference voltage. Additionally, a supplemental lighting system may have a rechargeable battery coupled to a low-voltage part of the circuit, for example protected by an isolation circuit. Furthermore, a lithium ion or similar rechargeable battery supply can include a circuit for allowing it to be used with a circuit designed for a NiCad powered system or with a circuit designed for a lithium ion powered system.
