Variable lumen output and color spectrum for LED lighting
First Claim
1. A power adjustment module for an LED lighting system, comprising:
- a normal power mode to set a current flow to the LED lighting system at a first value that can be sustained indefinitely without the determined temperature exceeding the maximum value for a given environment;
a temperature module to determine a temperature associated with the LED lighting system and compare it with the maximum value;
a manual, user selectable turbo boost mode to set a current flow to the LED lighting system at a second, higher unsustainable value for the given environment; and
a threshold module to automatically decrease the current flow to the LED lighting system based on the determined temperature being within a predetermined range of the maximum value, such that the LED lighting system is automatically transitioned out of the manually selected turbo boost mode.

Abstract
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.
