Official abstract text for this publication.
An accent lamp ( 10 ) having a solid state light source ( 4 ), such as LEDs, is attachable to a rear surface of an automotive headlamp ( 40 ) opposite the light-generating capsule ( 44 ). Accent lamp ( 10 ) has first retaining member ( 20 ), such as a clamp, formed above printed circuit board ( 8 ) on which LED ( 4 ) is mounted. Headlamp base ( 60 ) defines light passageway ( 45 ), formed as a light guide ( 42 ), extending from outermost peripheral surface ( 63 ) to an upper surface ( 61 ) on which lamp capsule ( 44 ) is retained. Accent lamp ( 10 ) is readily detachably mounted to headlamp ( 40 ), preferably by resilient first and second retaining members ( 20, 24 ), and, when mounted, can be biased to promote optical coupling of light source ( 4 ) to light guide ( 42 ).
Opening claim text (preview).
What is claimed is: 1. An accent lamp ( 10 ) removably attachable to an automotive headlamp ( 40 ) having a headlamp base ( 60 ) carrying a headlamp capsule ( 44 ), the headlamp base ( 60 ) having a light passageway ( 45 ) opening at an underside ( 63 ) of the headlamp ( 40 ) at a light entrance window, the accent lamp ( 10 ) comprising: a base ( 2 ); a solid state light source ( 4 ) disposed on a mounting surface ( 8 ) attached to the base ( 2 ), the solid state light source ( 4 ) arranged to emit light in a principal direction (P) away from the mounting surface ( 8 ); a first retaining member ( 20 ) disposed on and formed integral with the base ( 2 ) and being adapted to attach and selectively detach to a first portion of the headlamp base ( 60 ), the first retaining member ( 20 ) being disposed at a height, as seen in a direction extending along the principal direction (P), above the mounting surface ( 2 ), the first retaining member ( 20 ) being resiliently biased relative the mounting surface ( 8 ); and a lens ( 6 ) disposed on the base ( 2 ) and optically coupled to the solid state light source ( 4 ), the lens defining a mounting seat configured to receive in biased relation the headlamp light entrance window when the headlamp is retained by the first retaining member ( 20 ), whereby the lens is urged to mechanically and optically couple to the headlamp being received at the first retaining member. 2. The accent lamp of claim 1 , wherein the first retaining member ( 20 ) comprises a first clamp. 3. The accent lamp of claim 2 , wherein the first clamp comprises two arms ( 22 ). 4. The accent lamp of claim 3 , wherein the two arms ( 22 ) of the first clamp are mutually confronting, thereby clampingly retaining the headlamp ( 40 ) received therebetween. 5. The accent lamp of claim 2 , wherein the first clamp is configured as a first collar having a first collar opening, the first collar opening defining a first passageway ( 28 ) configured to receive the first portion of the headlamp base ( 60 ). 6. The accent lamp of claim 5 , further comprising a second retaining member ( 24 ) disposed on the base ( 2 ) and being adapted to attach and selectively detach to a second portion of the headlamp base ( 60 ), wherein the second retaining member ( 24 ) comprises a second clamp configured as a second collar having a second collar opening, the second collar opening defining a second passageway ( 30 ) configured to receive the second portion of the headlamp base ( 60 ). 7. The accent lamp of claim 6 , wherein the first and second passageways ( 20 , 24 ) open in approximately the same direction. 8. The accent lamp of claim 1 , further comprising a second retaining member ( 24 ) disposed on the base ( 2 ) and being adapted to attach and selectively detach to a second portion of the headlamp base. 9. The accent lamp of claim 8 , wherein the first and second retaining members ( 20 , 24 ) are disposed at different heights above the mounting surface ( 8 ). 10. The accent lamp of claim 9 , wherein the first and second retaining members ( 20 , 24 ) are arranged approximately parallel to each other. 11. The accent lamp of claim 8 , wherein the first and second retaining members ( 20 , 24 ) are arranged approximately parallel to each other. 12. The accent lamp of claim 8 , wherein the second retaining member ( 24 ) comprises a second clamp. 13. The accent lamp of claim 12 , wherein the second clamp comprises two arms ( 26 ). 14. The accent lamp of claim 1 , wherein the first retaining member ( 20 ) is disposed on a resilient post ( 18 ) extending upward from the base ( 2 ). 15. The accent lamp of claim 14 , wherein the resilient post ( 18 ) extends in the direction (P) away from the base ( 2 ). 16. The accent lamp of claim 1 , wherein the first retaining member ( 20 ) is configured to attach underneath to a neck portion underneath locking tabs ( 70 ) of an SAE 9005 (EC HB3)-type headlamp. 17. The accent lamp of claim 1 , wherein the solid state light source ( 4 ) comprises a plurality of light-emitting diodes. 18. The accent lamp of claim 1 , wherein the lens is a collimating lens ( 6 ). 19. The accent lamp of claim 1 , further comprising a second retaining member ( 24 ) spaced from the first retaining member ( 20 ), and wherein the first retaining member ( 20 ) and the second retaining member ( 24 ) are configured to attach to the headlamp base ( 60 ) of an SAE 9005 (EC HB3)-type headlamp. 20. The accent lamp of claim 1 , further comprising a second retaining member ( 24 ) spaced from the first retaining member ( 20 ) by a distance configured to attach the first and second retaining members ( 20 , 24 ) at approximately mutually transverse regions of the headlamp base ( 60 ) of an SAE 9005 (EC HB3)-type headlamp.
