<p>Disclosed is a pavement marker. A solar cell assembly is arranged between an upper case defined with a sunlight opening and a lower cover formed with a stem portion. The solar cell assembly has solar cells and light emitting lamps. Reflective plates are respectively attached to both side surfaces of the upper case. The solar cell assembly includes a transparent resin block having an upper wall, support protrusions are formed on an inner surface of the upper wall, and a solar cell set having the solar cells and a printed circuit board is disposed in the transparent resin block to be brought into contact with the support protrusions. Airtight bosses are horizontally and projectedly formed on both side surfaces of the transparent resin block, lead wire insertion holes are defined through both side walls of the transparent resin block in the airtight bosses, respectively, and the light emitting lamps are respectively fitted into the airtight bosses and electrically connected with the solar cell set through the lead wire insertion holes, with only base portions of the light emitting lamps received in the airtight bosses and body portions of the light emitting lamps projecting out of the airtight bosses. Epoxy layers are formed inside the transparent resin block such that the solar cell set is sandwiched between the epoxy layers, the lead wire insertion holes are sealed and the light emitting lamps are firmly fixed with respect to the airtight bosses.</p> |
