FIG. 7 is a timing chart showing an example of a change in the amount of light of the lamps 201 to 203 in FIG.

Referring to FIG. 7, since the light emission patterns of lamps 201 to 203 are different from each other, each lamp shows a different change in the amount of light.

As described above, it is possible to adjust the magnitude of the light fluctuation by changing the time T1 during which the light amount becomes small (or becomes non-light). Also, by changing the time T2, which is the cycle of the change in the amount of light, the cycle of the light fluctuation can be adjusted.

In FIG. 7, the maximum light amount is the same, but the state of light fluctuation can be changed by further changing the light amount to various sizes.

Therefore, the light seen through the receptacle 4 changes in brightness and fluctuates in accordance with the balance of the amounts of light of the three lamps 201 to 203, so that the light transmitted through the milky white globe 17 becomes more bright and dark. The changes and fluctuations are emphasized, as if the candle were burning in the glove.
