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.
Claims4
A light emitting diode module comprising:
- a light emitting chip;
- a phosphor layer formed of phosphor materials emitting light having a longer wavelength 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 light emitted from the phosphor layer,
- wherein a concavo-convex pattern is formed on the surface of the reflection plate which faces the light emitting chip.
The light emitting diode module of 1, wherein the concavo-convex pattern is a hemispherical array or a polygonal cavity array.
