PROBLEM TO BE SOLVED: To provide an LED lamp capable of suppressing the junction temperatures of an LED and an electronic component which are mounted on a substrate to low degrees by preventing the thermal interference between the LED and the electronic component.SOLUTION: An LED lamp 1 is configured such that a substrate 6 on which an LED 4 and a transistor (heat emitting element) 5 other than the LED 4 are mounted is housed in a space S formed by a housing 2 and a lens 3 covering the opening of the housing 2. In the LED lamp 1, a resistor (low power consumption element) 7 is arranged between the LED 4 and the transistor 5 on the substrate 6. Through holes 6a are formed on both sides of the resistor 7 on the substrate 6 with the resistor interposed therebetween. One ends of lead wires 12 are passed through the through holes 6a and connected to the substrate 6. The plurality of through holes 6a and the resistor 7 are arranged in a straight line. |
