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 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

Disclosed is a display device, elongate mount, and display module for displaying alphanumeric information to passengers of a mass transit vehicle. The display modules are mounted along a single edge to a elongate mount. The elongate mount includes at least one end cap which is made of a vibration dampening material. The louver of the display device includes a substantially continuous pressure member in order to place substantially continuous elongate contact to an area of an LED board that houses at least one heating element. The at least one heating element is covered by a thermally conductive foam that transmits heat from the elements to a heat sink of the display module.

Display device with rail support

Method of installing an electronic display device on a vehicle

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.
