White Light Emitting Diodes (LED) replace HID lamps in street lighting system to include a dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width ...
LED headlights in cars require precise intensity control over lifetime and over temperature. Automotive headlight control levels typically require multiple nested closed control loops to compensate ...
In use, lower light intensities favor more ordered crystalline regions, while higher intensities suppress crystallization, yielding softer, more transparent material. By projecting grayscale patterns ...
