PROBLEM TO BE SOLVED: To provide an LED lighting device capable of suppressing temperature rise of an LED by easily increasing a heat dissipation area in response to an increase in the amount of light without increasing costs.SOLUTION: An LED lighting device 1 is configured such that an LED 2 serving as a light source and a substrate 3 mounted with the LED 2 are housed in a sealed case 4, the substrate 3 is in close contact with a portion of the sealed case 4 exposed to the atmosphere, and a plurality of heat dissipation fins 5 are formed integrally on the outer surface of the sealed case 4. A heat dissipation member being a separate body from the sealed case 4 can be mounted on the sealed case 4. For example, heat dissipation blocks 10, each of which serves as the heat dissipation member, can be mounted on mounting seats 8 formed integrally between the heat dissipation fins 5 on the sealed case 4. |
