Light-emitting device
A light-emitting device includes a circuit board to which external electric power is supplied, a light emitting diode that is electrically connected onto the circuit board and emits light based on electric power from the circuit board, a housing provided on the circuit board so as to surround the light emitting diode and so that the upper end portion of the housing is positioned above the upper end portion of the light emitting diode, and a fluorescent laminate provided on the housing. The fluorescent laminate includes a first fluorescent layer that emits fluorescent light and a second fluorescent layer that emits fluorescent light having a wavelength that is longer than that of the first fluorescent layer. The second fluorescent layer is disposed on the housing and the first fluorescent layer is laminated on the second fluorescent layer.
