<P>PROBLEM TO BE SOLVED: To provide a street light capable of using even at a place where commercial power supply is hardly secured, and capable of using not only for lighting but also for a signboard such as for advertisement, guiding, and public communications. <P>SOLUTION: The street light has a photovoltaic generation panel 4 installed on the upper part of a pole 2, an illumination lamp 3 equipped on an illumination lamp arm 10, a support arm 9 installed between the lower portion of the photovoltaic generation panel and the illumination lamp arm 10, and a signboard 5 installed inside the pole 1, the illumination lamp arm 10, and the support arm 9. The illumination lamp 3 is lighted by the electricity generated by the photovoltaic generation panel 4, and the photovoltaic generation panel 4 is adjustable by an angle adjuster for horizontal angle and/or vertical angle. A power storage device which can store power generated by the photovoltaic generation panel 4 can be installed inside or outside the pole 1. The signboard 5 has a light source arranged in the inside space between the opposed surface side panel and the rear panel, and can make it an illumination type signboard capable of lighting the display plate by the light from the light source or a non-illumination type signboard. <P>COPYRIGHT: (C)2008,JPO&INPIT |
