摘要： In one embodiment, the present disclosure provides a method for controlling a plurality of LED channels. The method includes receiving an LED brightness signal having a plurality of superimposed pulse width modulated (PWM) brightness signals each having a duty cycle and amplitude at a unique modulation frequency, each PWM brightness signal being proportional to the brightness of a respective LED channel. The method also includes determining a pulse area of each PWM brightness signal at each respective unique frequency. The pulse area is proportional to the product of the amplitude and the duty cycle. The method also includes generating pulse area signals proportional to the respective pulse area and comparing the respective pulse area signals to user defined and/or preset photometric values to generate respective error signals proportional to the difference between the respective pulse area signals and the user defined and/or preset photometric values.

摘要： A pulse-excited mercury-free lamp system, and method of sustaining the emission of light emission from such a lamp, is provided. The system includes a light-transmissive envelope having an inner surface and a phosphor layer coated thereon. A discharge-sustaining gaseous mixture of a noble gas, at a low pressure, and a metal halide, is retained inside the light-transmissive envelope. An electrical system provides a plurality of pulses to the discharge-sustaining gaseous mixture, resulting in a discharge, which causes the lamp system to emit light. The emission of light is maintained by turning the discharge on during a pulse width of each pulse in the plurality of pulses and by turning the discharge off during a remainder of each period in the plurality of pulses. Particularly in systems where the metal halide is indium-based, this maintains an efficient emission of light without the use of mercury.

摘要： A light emitting diode (LED) controller for controlling a plurality of LED channels includes channel select circuitry, detection circuitry, and error processor circuitry. The channel select circuitry is configured to drive N−1 LED channels of a plurality of (N) LED channels at a nominal modulation frequency and to selectively drive a selected one of the N LED channels at a probe modulation frequency. The detection circuitry is configured to receive a composite brightness signal corresponding to brightness signals from the N LED channels. The detection circuitry is further configured to filter the composite bright signal and generate a selected brightness signal corresponding to a brightness of the selected LED channel at the probe modulation frequency. The error processor circuitry is configured to compare the selected brightness signal to user defined and/or preset photometric quantities and generate a control signal for adjusting the brightness of the selected LED channel.
