In one embodiment, an LED light bulb 1 includes an LED module 2, a base portion on which the LED module 2 is disposed, and a glove 4 attached to the base portion 3. The LED module 2 includes an ultraviolet to violet light-emitting LED chip 8 mounted on a substrate 7. A lighting circuit and a bayonet cap 6 are provided in and on the base portion 3. A fluorescent film 9 is provided on an inner surface of the glove 4, and emits white light by absorbing ultraviolet to violet light emitted from the LED chip 8. The fluorescent film 9 has a film thickness in a range of 80 to 800 µm. In the LED light bulb 1, an amount of ultraviolet light which leaks from the glove 4 is 0.1 mW/nm/lm or less. |
