Abstract

An LED lighting system is disclosed, which generally consists of an enclosure, one or more LED modules, one or more transformers, and one or more drivers. A lamp assembly is disclosed, which generally consists of one or more vertically oriented LED chips, thermally conductive shells, and a thermally dissipating means positioned at the back of the LED chips. An LED module is disclosed, which generally consists of a lamp assembly, one or more reflectors and modules caps. A method of controlling light intensities is disclosed, which generally consists of method of decreasing light intensities in areas with little occupancy while minimizing user annoyance resulting from drastic light intensity fluctuations. A universal mounting bracket is disclosed, which generally consists of a fixture plate, mounting plate, and an adjustable means.

Claims

1. A method for controlling a lighting system comprising the steps of:

(a) initial power on of light system at standby intensity level;

(b) detecting occupancy;

(c) determining light intensity based on detection of occupant;

(d) incrementally decrease standby intensity of light with continued non-occupancy;

(e) detect occupancy, increase light intensity to maximum while occupant present, incrementally increase standby intensity of light upon the departure of occupant;

(f) repeat steps (a) through (e) until end of work day; and

,

(g) end of work day lock standby light intensity and operates as simple set user described pattern.
