Abstract
The lighting system according to the present invention includes an electrical wiring substrate in which a connector to a power source is formed, a plurality of LED chips mounted in a predetermined array pattern on the electrical wiring substrate, a deflection lens array disposed in proximity to the LED chips between the LED chip and the predetermined illumination region and a housing for receiving the electrical wiring substrate and the deflection lens array. A plurality of deflection lenses are integrally molded in the deflection lens array to lead lights from the LED chips to the predetermined illumination region in a state where the lights from the LED chips are superposed with each other. The lights emitted from the LED chips are collected in a state where they all are superposed in a common, single illumination region through the deflection lenses.
