Abstract
The invention includes one or more LED elements, a silicon substrate on which the LED elements are mounted via micro bumps and internally formed wiring is connected to the micro bumps, a heat insulation organic substrate which is stuck to the opposite side of the LED elements-mounting side of the silicon substrate and has through-holes in which the wiring goes through, a chip-mounting substrate which is stuck to the opposite side of the silicon substrate side of the heat insulation organic substrate and internally formed wiring is connected to wiring in the through-holes of the heat insulation organic substrate, and an LED control circuit chip which is connected to the wiring of the chip-mounting substrate via micro bumps, and mounted via the micro bumps on the opposite side of the heat insulation organic substrate side of the chip-mounting substrate.
