Claims
- 1. A vehicular lamp comprising:
a housing; a single light emitting diode as a light source, adapted to attach to a base of said housing and capable of emitting a minimum flux of approximately 20 lumens; a lens, adjacent to said light emitting diode, having a front wall and a side wall, wherein said front wall is spherical and comprises a front surface and a rear surface; said rear surface of said lens comprising a plurality of catadioptric prism rings, an aspheric center lens, and a plurality of linear prism optics for distributing the light emitted from said light emitting diode horizontally and vertically; wherein the combination of said prism rings, said center lens, and said linear prism optics produce a composite light distribution with a minimum angulation substantially 10° above and below the longitudinal axis of said lamp and a minimum angulation substantially 20° left and right of the vertical axis of said lamp.
- 2. The lamp according to claim 1 wherein said light emitted from said light emitting diode has a substantially Lambertian radiation pattern.
- 3. The lamp according to claim 1 wherein said housing and said lens are substantially oval and said lens is adapted to engage with said housing.
- 4. The lamp according to claim 1 further comprising a heat sink adapted to secure to said housing and adapted to contact said light emitting diode to dissipate heat away from said light emitting diode.
- 5. A lamp according to claim 1 further comprising a circuit board operatively connected to a power source to provide an input voltage of approximately 13.5 Volts to said light emitting diode.
- 6. A lamp according to claim 5 further comprising potting material for embedding said light emitting diode and said circuit board.
- 7. The lamp according to claim 1 wherein said lens is red to allow said lamp to function as a stop, turn and tail lamp.
- 8. The lamp according to claim 7 wherein said lamp can also function as a marker lamp.
- 9. The lamp according to claim 1 wherein said lamp is adapted to mount to a vehicle either horizontally or vertically.
- 10. The lamp according to claim 9 wherein said lamp, mounted horizontally or vertically, satisfies the minimum photometric requirements of the Society of Automotive Engineers Standards J1398 when said lamp is functioning as a stop lamp; the Society of Automotive Engineers Standards J1395 when said lamp is functioning as a turn lamp; the Society of Automotive Engineers Standards J585 when said lamp is functioning as a tail lamp; the Society of Automotive Engineers Standards J592 when said lamp is functioning as a marker lamp.
- 11. The lamp according to claim 1 wherein said composite light distribution has a minimum luminous intensity of 16 candelas 10° above and below the longitudinal axis and 5° left and right of the vertical axis; a minimum flux of 10 candelas 5° above and below the longitudinal axis and 20° left and right of the vertical axis; a minimum flux of 30 candelas 5° above and below the longitudinal axis and 10° left and right of the vertical axis; a minimum flux of 70 candelas 5° above and below the longitudinal axis and 0° left and right of the vertical axis; a minimum flux of 40 candelas 0° above and below the longitudinal axis and 10° left and right of the vertical axis; a minimum flux of 80 candelas 0° above and below the longitudinal axis and 5° left and right of the vertical axis; and a minimum flux of 80 candelas 0° above and below the longitudinal axis and 0° left and right of the vertical axis when said lamp is functioning as a stop or turn lamp.
- 12. The lamp according to claim 1 wherein said composite light distribution has a minimum luminous intensity of 0.4 candelas 10° above and below the longitudinal axis and 5° left and right of the vertical axis; a minimum flux of 0.3 candelas 5° above and below the longitudinal axis and 20° left and right of the vertical axis; a minimum flux of 0.8 candelas 5° above and below the longitudinal axis and 10° left and right of the vertical axis; a minimum flux of 1.8 candelas 5° above and below the longitudinal axis and 0° left and right of the vertical axis; a minimum flux of 0.8 candelas 0° above and below the longitudinal axis and 10° left and right of the vertical axis; a minimum flux of 2 candelas 0° above and below the longitudinal axis and 5° left and right of the vertical axis; and a minimum flux of 2 candelas 0° above and below the longitudinal axis and 0° left and right of the vertical axis when said lamp is functioning as a tail lamp.
