Abstract
A light emitting diode module having improved luminous efficiency is provided. The light emitting diode module includes: a light emitting chip; a phosphor layer formed of phosphor materials emitting light having a wavelength longer than the light emitted from the light emitting chip using light emitted from the light emitting chip as an excitation source; and a reflection plate that is disposed between the light emitting chip and the phosphor layer and that reflects the light emitted by the phosphor layer.
