Lighting Device For The Interior Of Motor Vehicles
In a lighting device with low intensity light-emitting light sources for incident lighting of areas in a motor vehicle interior, the light sources are distributed in a mount above a converging lens, and aligned via the converging lens onto at least one area to be illuminated in the interior.
1 .- 13 . (canceled)
14 . A device for incident lighting of areas in a motor vehicle interior, said device comprising:
a plurality of low intensity light-emitting light sources; and
a converging lens; wherein,
the light sources are placed in a distributed manner in a mount above said converging lens; and
the light sources are aligned via the converging lens onto at least one area to be illuminated in the interior.
15 . The device as claimed in claim 14 , wherein the converging lens is fastened in the roof lining of the vehicle.
16 . The device as claimed in claim 14 , wherein a center point of at least one light source and a center point of the area to be illuminated thereby lie substantially on a straight line through an optical center point of the converging lens.
17 . The device as claimed in claim 14 , wherein the converging lens is a spherical lens.
18 . The device as claimed in claim 14 , wherein the light sources are light-emitting diodes.
19 . The device as claimed in claim 14 , wherein the extent of the illuminated areas is determined by the number or size of adjoining light sources on the mount.
20 . The device as claimed in claim 14 , wherein the converging lens comprises an acrylic polymer.
21 . The device as claimed in claim 14 , wherein the mount is a spherically shaped grid.
22 . The device as claimed in claim 14 , wherein the converging lens ( 1 ) is inserted fixedly in a recess, corresponding to the outline of the converging lens, in a fastening plate and is fastened by means thereof in the roof lining.
23 . The device as claimed in claim 22 , wherein an intended alignment of the converging lens is predetermined by inclination of the recess in relation to the fastening plate.
24 . The device as claimed in claim 22 , wherein the mount is fastened to the fastening plate.
25 . The device as claimed in claim 14 , wherein the light sources are connected to and are switchable on and off individually by, a control unit.
26 . The device as claimed in claim 25 , further comprising:
sensors connected to the control unit for detecting an intended control operation; and
wherein predetermined light sources may be switched on or off by the control unit in accordance with signals received from the sensors.
27 . A light source for selectively illuminating targeted areas, said light source comprising:
a converging lens;
a mounting structure disposed adjacent to said converting lens, and having a contour that accommodates an adjacent contour of the converging lens;
a plurality of light sources mounted on said mounting structure, facing toward said adjacent contour of said converging lens; and
control means for illuminating selected ones of said light sources, opposite said targeted area.
28 . The light source according to claim 27 , wherein said converging lens is a spherical lens.
29 . The light source according to claim 27 , wherein said light sources are light emitting diodes.
30 . The light source according to claim 27 , wherein said control means controls an extent and location of an illuminated area by controlling the number and size of adjoining light sources which are illuminated.
31 . The light source according to claim 27 , wherein a center point of at least one light source and a center point of the targeted area lie substantially on a straight line through an optical center point of the converging lens.
