Abstract
A flexible liquid tight marker light that comprises a light source encapsulated by injection molding a light transmitting elastomeric polymer to form a protective casing which further includes an imbedded wiring harness electrically connected to said light source and imbedded structural members that protect the light source from excessive flexing and impacts. The wiring harness and structural members provide heat sink means for the light source. The casing is comprised of variable durometer tinted polyurethane elastomers with light diffusing pigments added. Diverging optics are molded into the casing outer surface.
Claims24
A lamp comprising:
- an elastomeric body,
- a plurality of light-emitting diodes embedded in said body,
- a plurality of elongated electroconductive elements interconnecting the light-emitting diodes,
- at least one substantially rigid means adjacent to at least certain ones of said light-emitting diodes to shield the diodes against damaging impact and bending loads, and
- an electrical power source connected with said electroconductive elements to energize said light-emitting diodes.
A lamp comprising:
- a molded elastomeric polymer body,
- a plurality of light-emitting diodes embedded within the body,
- a plurality of electroconductive elements in said body and interconnecting said light emitting diodes, said electroconductive elements providing a heat sink for heat generated by said light-emitting diodes,
- at least one substantially rigid portion of said elastomeric body adjacent to at least certain ones of said light-emitting diodes to shield the diodes and electroconductive elements against damaging impact and bending loads, and
- an electrical power source connected with said electroconductive elements to energize said light-emitting diodes.
A lamp comprising:
- a polymer body comprising substantially discrete portions of different durometer materials,
- said polymer body having a first inner core portion comprising substantially rigid thermoplastic material and a second outer portion disposed about said first inner core portion and comprised of thermoplastic elastomeric material of different durometer,
- a plurality of light-emitting diodes embedded in said body first inner portion,
- a plurality of elongated electroconductive elements interconnecting the light-emitting diodes,
- electrical input conductors extending into said body and providing heat sink means for heat generated by the light-emitting diodes, and
- an electrical power source connected with said electroconductive elements to energize said light-emitting diodes.
