Abstract
A method and apparatus is provided for a multiple light-source illuminating device, the design and construction of which is derived from the lighting requirements of a specific lighting application. The resulting illuminating device () provides illumination according to the principles of lighting practice for the optimal performance of visual tasks. Coupling with sensors () and logical control () allows illumination intensity and spectrum to be varied according to changing user needs. The illuminating device includes multiple discrete light emitting components of different spatial intensity distribution and color spectrum mounted in specific orientations such that the application oriented combined lighting effect is created. The control is provided via a differentiated power supply () capable of affecting the current, voltage and duty cycle determining the relative contribution of each light source effecting a different spatial intensity distribution and color spectrum.
