VARIABLE LUMEN OUTPUT AND COLOR SPECTRUM FOR LED LIGHTING

摘要

An adjustable LED lighting system may allow for a variable lumen output, an estimation of remaining life expectancy, and/or control of lighting intensity, color temperature, and/or wavelength distribution. An LED lighting system may be capable of mimicking externally monitored, remote controlled, pre-defined, user-selected, or other lighting conditions. An LED lighting system may allow for a variable lumen output by monitoring a temperature associated with one or more LEDs and increasing or decreasing current flow to maintain the monitored temperature below a maximum temperature. The remaining life may be estimated based on historical runtime and temperature data.

主权项

1. An LED lighting system, comprising:
an arrangement of light-emitting diodes (LEDs); at least one driver configured to drive the arrangement of LEDs; at least one heat sink configured to dissipate thermal energy produced by the LEDs; a wireless interface configured for connecting with a control device in a remote location relative to the arrangement of LEDs; a configuration module configured to receive configuration instructions through the wireless interface from the control device in the remote location relative to the arrangement of LEDs, wherein the configuration instructions include lighting characteristics for each of a plurality of time periods that each specify at least a lighting intensity and a lighting color temperature; a driver control module configured to control the at least one driver to cause the arrangement of LEDs to emit light having the specified lighting intensity and lighting color temperature during each of the plurality of time periods; and a power adjustment module configured to modify a current flow to maintain a thermal temperature associated with the LED lighting system below a maximum value.
