PROBLEM TO BE SOLVED: To provide a light-emitting module with high luminance.SOLUTION: A light-emitting module 40 includes: an LED chip 42; a sheet-shaped phosphor layer 44 which is arranged so as to face a light emitting surface 42a of the LED chip 42, and which converts wavelength of light emitted by the LED chip 42; and a filter layer 46 which, among surfaces of the phosphor layer 44, is formed on at least either a side surface or the surface facing the LED chip 42, and which allows the light emitted from the LED chip 42 to pass through, and reflects the light of which the wavelength has been converted by the phosphor layer 44. The filter layer 46 is constructed so that, relative to the total energy of outgoing light, ratio of the outgoing light energy which is within a range of plus or minus 60 degrees from a front direction is at least 80%.SELECTED DRAWING: Figure 3 |
