Abstract
A light unit includes a tubular part, a shade, a collar, a connector, a circuit board unit and a cover. The tubular part has a flange with multiple first holes and multiple outer fins are located on the outside of the tubular part. A lip extends from the top opening of the shade and second holes are defined through the lip. The shade is mounted to the tubular part to rest the lip on the flange. The collar further has third holes and is mounted to the tubular part. The connector is fixed to the top of the tubular part and Light Emitting Diodes are connected to the circuit board unit and located in the tubular part. The cover is connected to the lower end of the shade. The heat generated by the Light Emitting Diodes is released via the first, second and third holes.
