Systems and methods for maintaining the illumination intensity of one or more LEDs above a minimal intensity level. The systems and methods may include: (1) a current regulator for regulating the current in a circuit; (2) a voltage source for applying current to a circuit; (3) an LED with a minimal intensity level that correlates to a set-point temperature; and (4) a thermal sensor that is in proximity to the LED and adapted to sense a temperature proximal to the LED. The thermal sensor may transmit a signal to the current regulator if the sensed temperature exceeds the set-point temperature. Thereafter, the current regulator may take steps to regulate the current in order to maintain the LED illumination intensity above the minimal intensity level.

Methods and systems for maintaining the illumination intensity of light emitting diodes

A direct lighting system and method is provided that includes a plurality of light-emitting diodes (LEDs) secured within a light fixture. The lighting system further includes a diffusive transmissive element adapted to transmit light from the LEDs therethrough and provide diffused light to an area requiring illumination.

Direct LED lighting system and method

A lighting system including a light-emitting diode cradle securing at least one light-emitting diode and a modular unit comprising an arcuate portion, the arcuate portion comprising at least one diffusive reflective surface adapted to receive and reflect light from the at least one light-emitting diode. The lighting system further includes a diffusive transmissive element adapted to receive light reflected by the diffusive reflective surface and provide diffused light to an area requiring illumination.

Lighting method and system

A lighting device that can generate light of variable color and intensity under processor control. Multiple lighting devices of a modular design can be incorporated into a lighting system to illuminate larger areas. A lighting module includes three groups of LEDs each of which generates light of a different color whose intensity can be controlled. A lighting system can be formed by coupling multiple lighting devices to a central controller comprising an operator interface panel and an interface to an external computer. The external computer can be provided with programming tools that allow the creation of lighting programs for controlling the operation of the lighting system. A user can select programs or modify the operation of the lighting system from the operator interface panel provided at the central controller or from the external computer. Procedures are provided for calibrating the color and power output of each lighting device.

LED lighting system

Method and system are disclosed for compensating for color variations due to thermal differences in LED based lighting systems. The method and system involves characterizing the LEDs to determine what PWM (pulse-width modulation) is needed at various operating temperatures to achieve a desired resultant color. The characterization data is then stored in the microprocessor either in the form of a correction factor or as actual data. When an operating temperature that is different from a calibration temperature is detected, the characterization data is used to adjust the PWM of the LEDs to restore the LEDs to the desired resultant color.
