    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 globe 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 globe, 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 globe is 0.1 mW/nm/lm or less.

    摘要： A white LED includes a light emitting element with a light emission peak wavelength equal to or longer than 380 nm and equal to or shorter than 420 nm, and a phosphor layer containing three or more types of phosphors including at least a blue phosphor, a green phosphor, and a red phosphor and disposed in a manner to cover at least part of the light emitting element. The phosphor layer has a first phosphor layer and a second phosphor layer disposed in an opposite side of a side of the light emitting element of the first phosphor layer. In the first phosphor layer, a content of the blue phosphor in an entire phosphor contained in the first phosphor layer is equal to or less than 5 mass %, or the blue phosphor is not contained. In the second phosphor layer, a content of phosphor other than the blue phosphor in an entire phosphor contained in the second phosphor layer is equal to or less than 5 mass %, or no phosphor other than the blue phosphor is contained.
