The channel-type controller 80 in Fig. 1 has a built-

It is possible to realize a desired channel type sequential light emission.

The EL sheet 30-1 of the channel type planar light source dial 100 of the printing type uses a light intensity sensor 56 to determine the daytime and nighttime conditions and the control unit 300 ).

The EL sheet 30-1 is configured to be turned on and off according to the lighting control output of the power supply unit 54. The power supply unit 54 is configured to turn on and off the solar cell 400, And the streetlight control voltage is selected as the drive voltage

And outputs it to the EL sheet 30-1 side.

That is, the lighting control of the EL sheet is controlled by the control unit 300.
