Conditions of effective light transmission through the hybrid lighting complexlight guides

The study results of the hybrid lighting complex optical path are introduced in this paper. Conditions of effective transmission of LED-module light emission by extended hollow tubularlight guides are defined. The conception of optical path with light transmission efficiency more than 99% is based on a stage circuit. The application of tubular light guide sending with collimator is feasible in this circuit for each step of circuit. The choice of LED block secondary optics of hybrid lighting complex is argumented. The best ratio between light guide optical characteristics and LED module secondary optics is defined. The best parameters for light transmission through extended hollow light guidesare achieved by application of secondary optics with the LED module light beam divergence angle equal to 30-60 degrees.
