摘要： A method of controlling a Fluorescent Lamp (CFL) is disclosed, which enables the lamp to be dimmed during a quick-start mode in which the lamp current may be boosted. The method involves determining a boost value and a dimming value, and controlling the lamp power in dependence on the boost and dimming values. A dimming threshold may be set, below which (i.e. at dimmer output light levels) the boost function is disabled. Hysteresis may be included in the control, in order to avoid hopping between modes. A controller for use with a fluorescent lamp which is adapted to operate according to such a method and a fluorescent lamp using such a controller are also disclosed.

摘要： A luminaire can comprise an electronic circuit, such as an LED driver or electronic ballast. A surge protection device in the current path between a power supply and the luminaire components can be configured to protect the electronic circuitry by absorbing and/or redirecting energy of a surge by switching into a low-impedance state while maintaining the protected circuitry (including its internal protective components, if any) in a high-impedance state. The surge protection device can comprise a MOV stage and a filter stage, for example. The surge protection device can be configured as a replaceable module, with the luminaire including an assembly designed to receive the module and allow for easy replacement over the useful life of the other components. Use of fuses or thermal components may cause the surge protection device to interrupt power flow if protection is lost due to internal failure, indicating when module replacement is needed.
