Abstract:
1. A light emitting device using an LED chip, comprising: a mounting substrate having a recess and having a wiring portion that supplies electric power to the LED chip, the LED chip being mounted on a bottom of the recess; a sheet-like wavelength converter disposed so as to cover the recess and an edge area around the recess and that is excited by light emitted from the LED chip to emit light of a wavelength different from an excitation wavelength; and an emission controller provided at a light output side of the sheet-like wavelength converter so as to allow emission of light coming from an area of the sheet-like wavelength converter that corresponds to the recess and to prevent emission of light coming from an area of the sheet-like wavelength converter that corresponds to the edge area around the recess.
