Abstract: A lighting system and a method are provided with an adaptive power balancing scheme which reduces or eliminates flicker by sensing the operation of a lamp that is connected to an electronic transformer and adaptively controlling the drive circuit of the lamp to prevent unexpected reset of the electronic transformer. There is provided a lamp with a light source and a drive circuit for the light source; said drive circuit has a power stage for regulating a voltage supplied to the light source, an energy storage device, and control means arranged to selectively disable the power stage. Power is provided to the light source by the energy storage device when the power stage is disabled.

Abstract: A lens for distribution of light predominantly toward a preferential side from a light emitter having an emitter axis. The lens has a faceted output region, a smooth output surface and at least one reflective surface which reflects light through total-internal-reflection (TIR) toward the faceted output region. The faceted output region is formed by pairs of transverse surfaces each surface of which redirects the received light to provide a composite illuminance pattern. The lens may further have faceted input surfaces at least partially defining a light-input cavity about the emitter axis. The faceted input region are formed by pairs of transverse surfaces each surface of which redirects the received light.
