Abstract

PURPOSE:To simplify a pilot lamp by installing a power capacitor which charges power generation output of a solar cell inside a bar main body provided with a solar light receiving plane and a light emitting lamp and lighting up the pilot lamp with the charges. CONSTITUTION:Light-emitting lamps Lepsilon are installed on a bar main body B which constitutes a pilot lamp where the light emitting lamps are designed to be and driven by a solar cell has a exposed solar light-receiving surface S on its surface and a power capacitor which keeps power output from the solar cell and discharging the electric charges to light the light-emitting lamps Lepsilon. A lighting control part is further installed on the bar main body B, thereby controlling a switch in conformity with this lighting switch and turns on and off the light emitting lamp L. The lighting switch is allowed to be interlocked with an optical sensor so as to control. It is also acceptable that a stanchion T may be replaced with a power generation stand equipped with a solar light receiving surface or the power capacitor or a lacing provided with light emitting lamps may be installed between the stands. This construction makes it possible to simplify a pilot lamp.
