A vehicle lamp capsulehaving a basehaving a springwhich, when lamp capsuleis installed, biases an inner surface of a vehicle lamp reflector. Springis monolithically formed with basealong with at least one reflector-locating structure on the base such as circumferentially extending exterior locating surfaceand/or retaining keys. Baseand springmay be molded of a plastics material. In other embodiments baseand springare made in one piece of sheet metal. The springformed unitary with the lamp basemeets regulatory requirements and avoids a risk of dislodgement of a conventional separate piece-part metal spring which could cause an electrical short when the lamp is installed in the field. The lamp capsuleis suitably an H13-style lamp.

Vehicle lamp base having integrally formed spring to bias reflector

Lamp modulecontains solid-state light sourceand has mounting flangecoupleable to headlamp reflector. Lamp modulehas basedefining central post, postdefining internal first air passage. Base and post act are heat sinks. Fanis disposed within base. Circuit boardhaving LED arraysis mounted inside postin fluid communication with first air passage. Basedefines second air flow passageexterior of post, second air passagebeing oriented to direct air past mounting flange. Basefurther defines third air passagerearward of mounting flangeand radially outward from second air passage. Mounting flangemay be keys coupleable to slots. A method of directing an air stream through slotsin reflector socketis described.

Vehicle LED lamp having recirculating air channels

A method of providing accent ornamental illumination to a lamp of a motor vehicle comprising providing an accent lamp comprising a housing and a light-emitting device disposed within the housing; mounting the housing to an exterior surface of the lens cover of the vehicle lamp; and arranging the light-emitting device such that, when the housing is mounted to the exterior surface of the lens cover of the lamp, light emitted from the light-emitting device passes through the lens cover from outside the lens cover towards a lamp reflector of the vehicle lamp and illuminates the reflector. A motor vehicle lamp combination comprising, in combination, a motor vehicle lamp and an accent lamp also provided wherein, when the accent lamp is mounted on a lens cover of the motor vehicle lamp, light emitted from the light-emitting device is directed towards the reflector.
