Abstract:
PURPOSE: To arrange the mounted as a substitution of a gate or gate lamp by lighting up plurality of light emitting diodes by electric energy generated from a solar battery and a storage battery and illuminating a name plate part. CONSTITUTION: Solar light in the daytime is converted into electric energy by the solar battery 2 and the electric energy is accumulated in the storage battery 5 and light emitting diodes are emitted on the back of the name plate 3 to emboss the name plate 3 with characters. Light emitting diodes having high conversion efficiency from electricity into light, especially green-yellow light emitting diodes are used for illumination conveniently for human susceptivity. Since an independent power supply requiring no external electric work is used, the storage battery 5 is used as a power supply for the diodes at night, the diodes are turned on after the delay of several hours from detected sunset to be reference time and turned off after midnight. Consequently the monument capable of lighting up the name plate part 3 and allowed to be arranged in the front of an entrance can be obtained.
