PROBLEM TO BE SOLVED: To safely and easily attach/detach a lighting device while reducing the cost and realizing a high heat dissipation property.SOLUTION: An LED lighting device includes: an LED substrate 24 on which an LED element is packaged; a lighting circuit board on which a lighting circuit component for supplying lighting power to the LED element is packaged; a translucent cover which covers an emission direction of the LED element; and a protection cover 26 which is located between the LED substrate 24 and the translucent cover and covers both the LED substrate 24 and the lighting circuit board without exposing them from the side of the emission direction of the LED element. The protection cover 26 is configured by mating and integrating a plurality of protection cover pieces. The LED lighting device has the high heat dissipation property by means of an air current flowing through a through-hole 26k formed at an inner edge and a notch 26m formed at an outer edge in the ring-shaped protection cover 26. |
