1-20. (canceled)
A lighting device comprising:
- a light emitting device having a light emitting chip;
- an optical plate corresponding to the light emitting chip;
- and
- a semi-transmissive mirror disposed under the optical plate and overlapped with the light emitting chip in a vertical direction,
- wherein the optical plate comprises:
- a phosphor layer;
- a first transparent film on a top surface of the phosphor layer;
- a second transparent film on a bottom surface of the phosphor layer;
- and
- a support surrounding the outer side of the phosphor layer,
- wherein the support is disposed between the first and second transparent films,
- wherein the semi-transmissive mirror is disposed between the phosphor layer and the light emitting chip, and
- wherein an area of a bottom surface of the semi-transmissive mirror is greater than an area of a top surface of the light emitting chip and smaller than n area of a bottom surface of the phosphor layer.
