Abstract
A pre-programmed energy saving ballast or driver is presented, having a pre-defined energy profile to which the output power is controlled in accordance with the current time ascertained from the input power connection via simplex clock information or from received broadcast time signals, and which allows a user to select from a number of pre-programmed profiles and/or to modify and store user-defined energy profiles.
Claims20
A pre-programmed energy saving lighting system, comprising:
- a power circuit operative to control provision of electrical power from an input power source to a light source;
- and
- an energy profile control component pre-programmed to signal the power circuit to control the provision of electrical power from the input power source to the light source according to a pre-programmed energy profile as a function of a current time value.
A method of operating a lighting system, the method comprising:
- storing a pre-programmed energy profile in a lighting system;
- providing electrical power from an input power source to a light source;
- and
- controlling the provision of electrical power from the input power source to the light source according to the pre-programmed energy profile as a function of a current time value.
