Abstract
A self-contained solar-powered illuminated safety marker having an improved housing design adapted for secure, flush-mounting into a road surface which includes a projection positioned to extend vertically downward from the bottom surface of the safety marker to secure the housing in its flush mounted position into a road surface and a solar cell with circuitry designed to illuminate the safety marker in response to a variety of environmental conditions.
Claims22
A safety marker, comprising:
- a housing comprising a base having a bottom portion, an upstanding side wall attached to the bottom portion to define a receptacle, the sidewall terminating in a flange having an upstanding peripheral edge defining a recess, a plurality of outwardly extending fins attached in generally spaced relationship about the periphery of the sidewall below the flange;
- projection having one end attached to the bottom portion with an opposing end extending vertically downward therefrom, the projection having a sidewall surrounding an opening, the sidewall of the projection having one or mare channel interleaved between ridge portions;
- and
- a cover shaped to conform to the recess in the flange to seal the receptacle.

A safety marker, comprising:
- a housing comprising a base having a bottom portion, an upstanding side wall attached to the bottom portion to define a receptacle, the sidewall terminating in a flange having an upstanding peripheral edge defining a recess, a plurality of outwardly extending fins attached in generally spaced relationship about the periphery of the sidewall below the flange;
- an interior, the circuit comprising:
- compartment positioned within the base of the housing;
- a circuit supported by the interior compartment:
- at least one first light source and at least one second light source mounted within said receptacle and arranged to transmit light from each source outwardly in a predetermined direction toward vehicular or pedestrian traffic;
- and
- at least one photovoltaic solar cell positioned within said receptacle to absorb sunlight as a source of electrical energy to power each of said at least one first light source and at least one second light source;
- a power storage unit configured to receive energy from the photovoltaic solar cell and store unused electrical energy generated by the solar cell;
- at least one light sensing circuit positioned within said receptacle and arranged to receive input from either said photovoltaic solar cell or said power storage unit and thereby produce an output signal;
- and
- a light control circuit configured to receive the output signal and energize said at least one first light source and at least one second light source in response to a low light condition;
- and
- a cover shaped to conform to the recess in the flange to seal the receptacle.
