PURPOSE: A hybrid sunlight system using sunlight and an LED are provided to supply constant energy regardless of change of the sunlight by using an LED as an auxiliary light source. CONSTITUTION: In a hybrid sunlight system using sunlight and an LED, a light collection unit(10) guides incident light to an optical fiber. The light collection unit includes a ferrule protection window which protects a ferrule. The optical fiber is fixed to the ferrule. The LED module(70~120) is connected to the light collection unit and the optical fiber. The LED module includes an LED and an LED light collecting coupler(20) which collects the sunlight and the LED light.
