Claims

[Scope of Claim for Utility Model Registration] (1) A tracking reflector that tracks the sun and reflects direct sunlight in a certain direction, and a converging lens consisting of a Fresnel lens that converges the reflected light from the tracking reflector. and a diffusing lens made of a Fresnel lens that converts the convergent light converged by the converging lens into substantially parallel light. (2) A funnel-shaped reflector with an aperture larger than the diameter of the convergent lens and whose inner surface is a reflective surface is provided outside the converging lens that converges the reflected light, and a funnel-shaped reflector is provided at the end of the funnel-shaped reflector. The lighting device according to claim 1, which is a registered utility model, characterized in that cylindrical light guide ducts each having a mirror surface are connected to each other. (3) Between the converging lens and the funnel-shaped reflector,
A second funnel-shaped reflecting mirror is provided, the diameter of which is equal to or larger than the diameter of the converging lens, smaller than the diameter of the funnel-shaped reflecting mirror, and whose inner and outer surfaces each serve as reflecting surfaces. A lighting device according to claim 2 of the utility model registration claim.
