A headlamp reflector 12, which accepts a conventional lamp capsule 10 having a sealing gasket 64, has a neck 2 defining a bore 40 and socket 50 to receive and retain lamp capsule 10 with capsule latching structure 52. Reflector neck 2 has a gasket seating surface 47 adjacent to which one or more recessed channels 43 are formed which define air passageways 70 that communicate between inner reflector cavity 19 and neck entrance region 46, allowing air passage past gasket 64 with capsule 10 retained in socket 50, while still allowing gasket 64 to position capsule 10 in reflector bore 40. Gasket seating surface 47 may be located displaced axially from capsule latching structure 52. Embodiments of reflector 12 accommodate a variety of popular, commercially available replaceable lamp capsules 10.

1. An automotive lamp reflector (12) adapted to receive an automotive lamp capsule (10) having a resilient gasket (64) and retaining keys (42) extending from a lamp base (20), the reflector (12) comprising: a neck (2) and a reflective optical surface (16) formed thereon, the optical surface (16) defining an inner reflector cavity (19);the neck (2) defining a bore (40) having a bore inner surface (44), the bore (40) extending in an axial direction (18) between a neck entrance region (46) and a neck exit region (48), the neck entrance region (46) sized to receive a lamp capsule (10) and facing away from the optical surface (16), the neck entrance region (46) opening to an exterior region (45) disposed outwardly exterior of the reflector (12);the neck exit region (48) being adjacent the optical surface (16), whereby the bore (40) communicates between the inner reflector cavity (19) and the exterior region (45);the neck further defining: a socket region (50) adapted to receive the lamp capsule (10) when positioned in the bore (40), the socket region (50) comprising a capsule latching structure (52) adapted to retain, at an axially predetermined position, the plurality of retaining keys (42) formed on the lamp base (20) of the lamp capsule (10);a gasket seating surface (47) axially displaced from the capsule latching structure (52) and configured to receive the lamp gasket (64) disposed on the lamp base (20) of the lamp capsule (10); andat least one channel (43) defined in the neck (2) adjacent to and recessed relative the gasket seating surface (47), said at least one channel (43) opening to the neck entrance region (46) and thereby bounding an air passageway (70) in fluid communication between the reflector cavity (19) and the neck entrance region (46),whereby when a lamp capsule (10) is received in the bore (40) with the lamp gasket (64) adjacent the gasket seating surface (47) and the retaining keys (42) of the lamp capsule (10) retained against the capsule latching structure (52) in the socket region (50), the air passageway (70) defined in the neck (2) permits communication of air between the optical surface (16) and neck entrance region (46). 2. The lamp reflector of claim 1, wherein the at least one channel (43) is formed as a recess in the neck (2). 3. The lamp reflector of claim 1, wherein the gasket seating surface (47) is defined along the bore inner surface (44) and the at least one channel (43) is defined by at least one axially extending recess along the bore inner surface (44) extending between the neck entrance region (46) and the optical surface (16). 4. The lamp reflector of claim 3, wherein the at least one channel (43) is recessed outwardly radially away from a reflector longitudinal axis (18). 5. The lamp reflector of claim 1, wherein the gasket seating surface (47) is defined at the neck entrance region (46) and the at least one channel (43) is recessed below a peripheral lip of the neck entrance region (46). 6. The lamp reflector of claim 1, wherein the bore inner surface (44) is cylindrical. 7. The lamp reflector of claim 1, wherein the at least one channel (43) comprises a plurality of channels (43) thereby defining a plurality of air passageways (70). 8. The lamp reflector of claim 1, wherein the capsule latching structure (52) comprises a plurality of lamp-retaining slots. 9. The lamp reflector of claim 8, wherein the lamp-retaining slots are of the bayonet type, whereby rotation of the lamp capsule (10) brings the retaining keys (42) into engagement with the capsule latching structure (52). 10. The lamp reflector of claim 8, wherein the lamp-retaining slots extend at least partially transverse the bore (40), whereby rotation of the lamp capsule (10) brings the retaining keys (42) into retention with the lamp-retaining slots. 11. The lamp reflector of claim 1 in combination with the lamp capsule (10), whereby when the lamp capsule (10) is disposed in the bore (40) and the retaining keys (42) are engaged in the latching structure (52), the at least one channel (43) defines the air passageway (70) between an outwardly facing surface of the gasket (64) and the gasket seating surface (47). 12. An automotive headlamp (6) comprising a lamp reflector (12) in combination with an automotive lamp capsule (10), comprising the reflector (12) defining an inner surface (16) and a neck (2) having a bore (40) extending between the reflector inner surface (16) and a neck entrance region (46) and defining a capsule-receiving region,the neck (2) further defining a capsule latching structure (52), the neck entrance region (46) being in communication with an exterior region (45) disposed outwardly exterior of the reflector (12);the lamp capsule (10) comprising a lamp base (20) on which is mounted a light source (11) and a gasket (64),wherein the lamp base (20) is latched in the capsule-receiving region, the light source (11) is disposed in optical association with the reflector inner surface (16), and the gasket (64) is seated in register with the neck (2) at a gasket seating surface (47) of the neck (2); andthe neck (2) further defining in the gasket seating surface (47) at least one air flow channel (43) extending across and bounded by the gasket (64) and thereby defining an air passageway (70) in communication between the reflector inner surface (16) and the exterior region (45). 13. The headlamp of claim 12, wherein the gasket (64) is disposed on an inner surface (44) of the bore (40). 14. The headlamp of claim 13, wherein the at least one channel (43) is recessed radially outward of the bore inner surface (44). 15. The headlamp of claim 12, wherein the gasket (64) is received on an outer peripheral surface of the bore (40) adjacent the neck entrance region (46). 16. The headlamp of claim 15, wherein the outer peripheral surface of the bore (40) is oriented facing axially downward. 17.
