PROBLEM TO BE SOLVED: To provide a black-body radiation spectral type LED lighting apparatus with high luminance, large output and flat plane emission which obtains a continuous spectrum similar to pseudo sunlight and is able to emit any desired visible light, thereby making it possible to overcome the difficulty controlling color rendering properties in a conventional structure where a coating of encapsulation resin composed of a plurality of mixed and dispersed phosphor powder is applied to a number of LED bare chips.SOLUTION: The black-body radiation spectral type LED lighting apparatus comprises: a metal substrate provided with a striped shielding wall having a slope face; a plurality of arranged LED bare chips joined to recessed surfaces of the metal substrate; a circuit board capable of controlling drive of the LED bare chips per array; an inner reflection frame which is an encapsulation frame 19 closely adhered to the surface of the metal plate and connected by wiring to the whole or part of the circuit board; and an optical system focused on a flat light emission module. |
