Estimating the term…
A method of accurately controlling at least one of an intensity, brightness, dimming or color mixing of a LED, the method comprising monitoring an actual current flowing through the LED, selecting a specific current based on at least one of a desired illumination intensity, a desired brightness, a desired dimming, or a desired color mixing, comparing said actual current and said specific current, and if a difference exists between said actual current and said specific current, adjusting said actual current to agree with said specific current.
A method of accurately controlling at least one of an intensity, brightness, dimming or color mixing of an LED, said method comprising:
A light emitting diode system for controlling at least one of an intensity, brightness, dimming or color mixing of an LED, said system comprising a control system including a microprocessor arranged to control a current value of said LED by comparing an actual current value with a desired current value and establishing a new actual current value.
A dynamic power management system for a point source LED having three or more colored LED sources wherein a LED manufacturing process requires that a maximum allowed current through each LED be dependent upon a total current supplied to all LED sources, said system comprises a microprocessor to analyze a total drive current to all LED sources wherein this information is used to modify drive current to each individual LED such that a total power dissipation of the LED sources is not exceeded.
