Abstract
Self-contained solar signs utilizing incident solar energy employing solar cells or thermal absorbers for generating electricity which is stored and later used for energizing sign illuminating lamp or lamps.
Claims4
A sign assembly employing incident solar energy for self-illumination thereof comprising in combination:
- a display sign,
- a plurality of photovoltaic solar cells mounted on said sign and exposed to the sun for collecting incident solar energy and converting it into electrical energy,
- said cells being mounted on a rack extending laterally from the top of said sign,
- battery means connected to said solar cells for receiving and storing the electrical energy generated by said solar cells,
- lamp means comprising at least one fluorescent tube mounted on said sign for periodic illumination thereof,
- timing means connected to said battery means for selective energization of said lamp means from said electrical energy stored in said battery means, and
- means connected between said battery means and said lamp means for converting the energy of said battery means into high voltage alternating electrical energy sufficient to operate said lamp means.
