Abstract
A light emitting diode unit comprising a light emitting diode chip, a reflecting unit, and a light condenser is provided in this invention. The light emitting diode chip is disposed on a substrate for providing a plurality of first light beams. The reflecting unit is installed on the substrate, surrounding the light emitting diode chip for reflecting the first light beams emitted from the light emitting diode chip, and sufficiently directing the first light beams upward. The light condenser is provided above the light emitting diode chip, having a light-incident pattern and a light-emitting flat plane, wherein the light-incident pattern faces to the light emitting diode chip for sufficiently receiving and guiding the first light beams upward via the light-emitting flat plane.
