A high output LED(Light Emitting Diode) bulb is provided to discharge the heat to the outside rapidly by forming an annular ventilation layer on a driving substrate. A power converter has an input terminal and an output terminal. A power source base(40) is coupled with an external power socket. The power source base is connected to the input terminal of the power converter. The driving substrate(20) is connected to the output terminal of the power converter. The driving circuit is formed on the driving substrate. The high output LED is mounted on the driving substrate. The case(10) covers the driving substrate. The driving substrate is made of the metal material. The driving substrate is exposed to the outside. The annular ventilation layer is formed between the disk of the metal material of the driving substrate. The power source base has the cylindrical shape. The screw thread is formed in the lower part of the outer circumference of the power source base to be coupled with a female screw part of the power socket. |
