Abstract: The present invention provides a method and apparatus for controlling the activation of an electronic device. For a desired activation ratio, which defines the "ON" time relative to the "OFF" time of the electronic device fo r a given time period, the method and apparatus according to the present invention evaluates an activation sequence. The activation sequence comprise s two or more activation time periods and one or more deactivation periods, wherein the ratio between the two or more activation periods and the predetermined time period is equivalent to the desired activation ratio.

Abstract: A system and method for controlling lighting are described. In general, the system and method may be used for controlling generation of light from the one or more lighting devices within a lighting system, in response to an external input. The control system generally comprises a control interface module and a light generation module. The control interface module is configured to receive the external input and convert same in accordance with a predefined internal control protocol. The light generation module is communicatively linked to the control interface module to receive the converted input and is operatively linked to the one or more light-emitting element modules for controlling generation of light thereby in accordance with the converted input. In one example, the light generation module is either interchangeable or interchangeably adaptable to receive the external input in accordance with one of two or more control protocols.
