First Claim
Patent Images
1. A clearance/side marker lamp for a motor vehicle comprising:
- a rigid housing;
a first plurality of light emitting diodes arranged within said housing and collectively operable to emit light generally in a first direction;
a second plurality of light emitting diodes arranged within said housing and collectively operable to emit light generally in a second direction, said second direction being arranged at an acute angle relative to said first direction;
a third plurality of light emitting diodes arranged within said housing and collectively operable to emit light generally in a third direction, said third direction being arranged at an acute angle relative to said first direction and at an obtuse angle relative to said second direction; and
a lens positioned in front of said plurality of light emitting diodes, said lens configured to receive light emitted in said first, second and third directions and spread said light in an arc of continuous light spanning approximately 180 degrees.

Abstract
A clearance and side marker lamp, or PC lamp, such as for truck/trailer combinations, is provided with LEDs mounted to a plurality of circuit boards. The circuit boards are mounted at predetermined angles relative to each other for directing light in at least three directions. A lens is provided in front of the LEDs and includes a series of prism optics for spreading the light emitted from the LEDs into an arc of up to 180 degrees.

8. A clearance/side marker lamp for a motor vehicle comprising:
-
a first circuit board having a first mounting surface for mounting at least one light emitting diode thereto; a plurality of secondary circuit boards each having a second mounting surface for mounting at least one light emitting diode thereto, each of said secondary circuit boards being rigidly attached to said first circuit board such that said second mounting surfaces are directed at a predetermined acute angle away from said first mounting surface; wherein said light emitting diodes are mounted to each of said circuit boards such that light emitted therefrom has a beam axis directed perpendicularly away from said mounting surfaces corresponding thereto; and a housing for receiving said circuit board assembly therein, said housing having a first surface for mounting said first circuit board thereto. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A clearance/side marker lamp for a motor vehicle comprising:
-
a housing having a front portion, a rear portion and a body disposed therebetween; a plurality of light emitting diodes arranged within said housing, said plurality of light emitting diodes being operable to emit light toward said front portion, toward said rear portion and away from said body; and a lens mounted to said housing in front of said light emitting diodes, said lens having means for spreading said light emitted by said light emitting diodes through a range of approximately 180 degrees from said front portion to said rear portion. - View Dependent Claims (16, 17, 18, 19)
