In that sense, in FIG. 3, the thickness of the phosphor 60 is slightly emphasized. Further, since the phosphor 60 is substantially white or milky white under visible light, that is, natural light, the phosphor 60 is covered with a semitransparent material. If it is applied to the inside of the phosphor, the presence of the phosphor 60 is not visually recognized from the outside when the near-ultraviolet ray is not emitted from the ultraviolet lamp 34. Instead of applying the coating material to the surface of the cover portion 20, the cover portion 20 itself may be kneaded to contain the phosphor.

Further, a phosphor 70 is fixed on the upper surface of the pedestal portion 12, which is also the same as the phosphor 60, and is made of a paint which emits visible light when irradiated with near ultraviolet rays. There is. This phosphor 70 is also a phosphor-containing coating material, and specifically, an inorganic fluorescent paint (inorganic phosphor).
Is. In this way, the upper surface of the pedestal portion 12 is subjected to the inorganic fluorescent processing. Since this phosphor 70 is white or milky white under visible light, in order to make it difficult to recognize the presence of this phosphor 70 under visible light, the color of the upper surface of the pedestal portion 12 is set to the phosphor. It is preferably the same color as 70.

The changeover switch 40 has an OFF mode, a first mode, and a second mode as the changeover positions. Then, in the off mode, the switches a1 to a
All 2 are turned off, and the first visible light lamp 32, the ultraviolet light lamp 34, and the second visible light lamp 36 are all turned off. In the first mode, the switches a0 and a2 are turned on, the first visible light lamp 32 and the second visible light lamp 36 are turned on, and the ultraviolet light lamp 34 is not turned on. In the second mode,
The switches a1 and a2 are turned on, the ultraviolet light lamp 34 and the second visible light lamp 36 are turned on, and the first visible light lamp 32 is not turned on.

That is, when the lighting device A1 is not used, the changeover switch 40 is set to the off mode, and when it is used as general lighting, the changeover switch 40 is set to the first mode. Further, when the decoration effect by the ultraviolet light lamp is obtained, the changeover switch 40 is set to the second mode.

That is, it becomes possible to secure the brightness. In this case, the near-ultraviolet ray is not emitted even when the first visible light lamp 32 is turned on, so the phosphor 60 provided inside the cover portion 20.
