Lighting device for e.g. architectural lighting, has control case and red, green and blue LED projectors, such that connection between case and projectors ensure power supply and control light intensity and color of projectors by two wires

摘要

The device has a control case and red, green and blue LED projectors, such that connection between the case and projectors ensure power supply and control light intensity and color of the projectors by two wires. The case has a microprocessor to address the projectors with color and intensity values, and a mono stable multivibrator whose output is provided to current generators that are utilized for illuminating LED diodes.
