摘要： 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.

摘要： A white light source system being an illumination light source for a variety of target objects, such as exhibits in an art gallery, that require high color-rendering properties similar to natural light and being capable of: taking into consideration regional and time differences and reproducing sunlight shone on to earth; and being capable of radiating white light having reduced ultraviolet or blue light-emission components that may have an adverse impact on paintings, etc. The white light source system uses at least four types of white light sources including a combination of ultraviolet and violet light-emitting LEDs and phosphors. As a result of adjusting types of phosphor material used and the mixing proportions for the white light sources, the white light source system continuously reproduces daily changes in sunlight for a specified season and a specified region and reproduces a white light that takes safety issues into consideration by improving a device structure.
