Light emitting diode unit

A light emitting diode unit, comprising:

• a base made of an anodized aluminum plate;
• a printed board disposed on an upper surface of the base and including a predetermined conductive pattern and an opening;
• at least one light emitting diode chip disposed on the base within the opening of the printed board and electrically connected to the conductive pattern;
• a lens member including a lens section configured to collect light emitted from the light emitting diode chip and a case having a concave portion that covers the light emitting diode chip and is attached to the printed board to create a space between the light emitting diode chip and the lens member;
• and
• a sealing resin filling the space and configured to seal the light emitting diode chip,
• the case including at least two sealing resin-injection holes adapted to fill the space with the sealing resin, and
• a multilayer coating film to increase reflectivity being formed on the upper surface of the base.
