Copper or aluminum of the end of an electric wire with a stripped coating is connected to a part which is electrically safe and conducts heat on a substrate on which an LED is mounted by corresponding to the number of LEDs or more. An electric wire bundle is withdrawn to the outside of an external case of an illumination lamp through a hole on the side of the external case of the illumination lamp and is connected to the copper or aluminum of the end of the electric wire in a heat discharger which is installed on a top part outside the external case or is separated from the external case. Thereby, heat is discharged from the LED. |
