Light emitting module
Abstract:
A light emitting module includes: an LED chip; a plate-shaped phosphor layer that is provided so as to face the light emitting surface of the LED chip and is configured to convert the wavelength of the light emitted by the LED chip; and a filter layer that is formed, of the surfaces of the phosphor layer, on at least one of the surface that faces the LED chip and the side surface, and that is configured to transmit the light emitted from the LED chip and to reflect the light whose wavelength has been converted by the phosphor layer. The filter layer is formed such that a ratio of the energy of the emitted light within a range of ±60° with respect to the front direction to the total energy of emitted light is 80% or more.
