Abstract: A light unit includes a light guiding body having a light entrance face. A base has a curved oval surface defined therein which has a first focus and a second focus. A light emitting unit is located at the first focus and generates light beams which pass through the second focus and enter into the light guiding body via the light entrance face. The base has a heat dissipating unit connected to outside thereof. The light beams generated from the light emitting unit are completely guided into the light guiding body to have high illumination efficiency. The heat dissipating unit brings the heat away from the light unit.
