Abstract

A combined approach lamp and logo lamp apparatus for use in an external rear view assembly comprising at least one aperture, the apparatus including a housing including a rear view face and a front face with the at least one aperture; a printed circuit board (PCB) mounted adjacent the rear face, the printed circuit board further including a power connector, an electronic circuit, a first light source mounted in a first location on the printed circuit board, and a second light source mounted in a second location on the printed circuit board, and a transparent lens component comprising a first lens portion and a second lens portion.

First claim

What is claimed is:

1. A combined approach lamp and logo lamp apparatus for use in an external rear view assembly comprising at least one aperture, the apparatus comprising:
a housing comprising a rear view face and a front face with the at least one aperture;
a printed circuit board (PCB) mounted adjacent the rear face, the printed circuit board further comprising:
a power connector;
an electronic circuit;
a first light source mounted in a first location on the printed circuit board; and
a second light source mounted in a second location on the printed circuit board; and

a transparent lens component comprising a first lens portion and a second lens portion,
wherein the housing and the lens component are formed as a two component moulded part so that the first lens portion is orientated to focus light from the first light source and the second lens portion is orientated to focus light from the second light source via an optical assembly comprising a logo element, and
the first lens portion is angled relative to a plane containing the PCB surface so that a distance from the first light source to an outer surface of the first lens portion is less than a distance from the second light source to an outer surface of the second lens portion, with, in use, the housing being mounted so that the first lens portion and the second lens portion are adjacent the at least one aperture in the side mirror housing,
wherein the at least one aperture comprises a first aperture and a second aperture separated by an opaque bridging portion,
the first lens portion is located in the first aperture and the second lens portion is located in the second aperture, and
the second lens portion is separated from the first lens portion by a joining portion, with the joining portion being covered by the opaque bridging portion.

2. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein the PCB has an area of at least 750 mm 2 , at least 900 mm 2 , or at least 1100 mm 2 .

3. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein the electronic circuit is configured to separately control the output of the first light source and the output of the second light source, and the output of each light source is controlled to limit the total output under a predetermined maximum thermal dissipation limit.

4. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein both light sources are actuated at the same time, with a resettable fuse for an overheat control being provided.

5. The combined approach lamp and logo lamp apparatus as claimed in claim 3 , wherein the electronic circuit is configured to operate the combined approach lamp and logo lamp apparatus in at least two modes, wherein in each mode the total output remains under a predetermined maximum thermal dissipation limit, and in the first mode both the first light source and the second light source are switched on, and in the second mode only one of the first light source or second light source is switched on, and generates light with an intensity larger than an intensity of the same light source when operated in the first mode.

6. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein the first lens portion is angled with respect to the plane containing the PCB surface, with at least one of the first lens portion being angled with respect to the plane containing the PCB surface with an angle in the range of 10° to 25° or 15° to 20°, or the first lens portion is of the light pipe type or multi-faceted.

7. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein the second lens portion is at least one of parallel to a plane containing the PCB surface or recessed.

8. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein the first light source comprises an approach lamp, the first lens portion has a first width and is mounted in a first offset position at an offset distance from an outer surface of a lower surface of the side mirror housing, and the approach lamp aperture has a second width which is wider than the first width of the first lens portion, with the approach lamp projecting light both forward and rearward at a forward angle between 50° and 65° and a rearward angle between 50° and 75°.

9. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , wherein a rear surface supports the PCB with the power connector, which comprises two prongs which engage with a plug which operatively connects the prongs to cables through a seal.

10. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , further comprising a power connector housing in a proximal face provided by the housing which is opaque and further comprises a first side face, a second side face and a distal face, the proximal face comprising an aperture for receiving at least one cable.

11. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , further comprising at least one of
a mounting flange for mounting the combined approach lamp and logo lamp apparatus to an interior housing of the external rear view assembly through an aperture, with the mounting flange being located on either the first side face or the second side face, and the rear surface engages with the housing to form a rear face; or
connection means for a screw, a snap or a clip connection for mounting the combined approach lamp and logo lamp apparatus to the external rear view assembly via an adaptor.

12. The combined approach lamp and logo lamp apparatus as claimed in claim 1 , further comprising an adjusting device for spatially adjusting the apparatus relative to a housing part of the rear view assembly, relative to at least one of a housing cap or a mirror foot cover,
wherein the adjusting device comprises at least one first adjusting element being arranged at the apparatus or formed together with an apparatus housing, provides at least one translational degree of freedom along at least one shifting axis or at least one rotational degree of freedom around at least one rotational axis.

13. An external rear view assembly for a motor vehicle, comprising the combined approach lamp and logo lamp apparatus as claimed in claim 1 .

14. The external rear view assembly as claimed in claim 12 , wherein at least one of
the adjusting device comprises at least one second adjusting element that is arranged at or formed together with a holding device for at least one of the apparatus or the housing part, or
the adjusting device comprises at least one fixing element for fixing the apparatus in a position adjusted using the adjusting device via at least one of one or more fixing screws or bonding.

15. A motor vehicle comprising an external rear view assembly as claimed in claim 13 .

16. A combined approach lamp and logo lamp apparatus for use in an external rear view assembly comprising at least one aperture, the apparatus comprising:
a housing comprising a rear view face and a front face with the at least one aperture;
a printed circuit board (PCB) mounted adjacent the rear face, the printed circuit board further comprising:
a power connector;
an electronic circuit;
a first light source mounted in a first location on the printed circuit board; and
a second light source mounted in a second location on the printed circuit board; and

a transparent lens component comprising a first lens portion and a second lens portion,
wherein the housing and the lens component are formed as a two component moulded part so that the first lens portion
