Abstract
An apparatus, system, and method for solid state lighting is envisioned which, according to aspects of the invention, provides primary event and/or utility lighting during normal power conditions, and which, during periods of interrupted power, provides uninterrupted event lighting for a desired duration, provides a gradual transition from event lighting levels to utility lighting levels, and provides a gradual transition from utility lighting levels to emergency lighting levels.
Claims17
A method of large area lighting for a lighting application comprising:
- a. providing illumination from an electrically-powered lighting system at:
- i. event lighting level;
- or
- ii. utility lighting level;
- b. upon a power interruption to the lighting system providing:
- i. uninterrupted event or utility lighting for a relatively short duration;
- and
- ii. a gradual transition from event or utility lighting to an emergency lighting level;
- iii. wherein the gradual transition comprises either a stepless or a step-wise change in lighting levels.
A system for providing large area lighting for a lighting application comprising:
- a. a plurality of high intensity light fixtures adapted to provide event or utility lighting levels;
- b. a power and control circuit to the fixtures in communication with an AC electrical power source;
- c. a sensor for sensing interruption of the AC electrical power source to the power and control circuit;
- d. a back up source of electrical power;
- e. a sub-system including a controller configured to;
- i. automatically change-over to the back up source of electrical power upon the sensing of interruption of the AC electrical power source;
- ii. automatically control operation of the power and control circuit of the fixtures to provide:
- 1. uninterrupted event or utility lighting for a relatively short duration;
- 2. a gradual transition from event or utility lighting to a wherein the gradual transition from event or utility to a lower level comprises gradually reducing lighting levels followed by shut down of the light fixtures and automatic turn on of separate emergency light level lighting fixtures.
A method of automatically controlling a wide or large area lighting system for such events as sports contests, automobile racing, or public shows comprising:
- a. providing sufficient electrical power from the public electrical power grid to provide illumination at:
- i. event lighting level;
- or
- ii. utility lighting level;
- b. upon sensing an interruption of grid power to the lighting system providing from an alternative power source:
- i. uninterrupted event or utility lighting for a relatively short duration;
- and
- ii. a gradual transition from event or utility lighting to an emergency
- iii. wherein status of the lighting system is communicated to a remote monitoring system and the remote monitoring system provides control signals to the lighting system to influence or control the transition from event or utility lighting to an emergency lighting level or to lighting levels as desired.
