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