Abstract:
Die Erfindung betrifft eine Fahrzeugleuchte, welche zumindest aufweist: eine Lichtquelle (1), die zumindest eine LED aufweist; ein lichtdurchlässiges Teil (2), das so angeordnet ist, dass es Licht von der Lichtquelle (1) empfängt; und ein Reflektor (3), der so angeordnet ist, das er den Teil des Lichts der. Lichtquelle (1) reflektiert und zur Vorderseite der Leuchte (5) auskoppelt, welcher durch das lichtdurchlässige Teil (2) hindurchgeht, wobei ein Reflexionsabschnitt und ein Brechungsabschnitt innerhalb des lichtdurchlässigen Teils vorgesehen sind, der Reflektionsabschnitt das von der Lichtquelle austretende Licht durch Totalreflektion zum einen in eine Richtung umlenkt, die im wesentlichen senkrecht zu der optischen Achse des Reflektors (3) verläuft und der Brechungsabschnitt das Licht in Richtung des Reflektor auskoppelt.
Abstract:
A lamp (1, 11, 14, 17) for a motor vehicle headlight is described. The lamp (1, 11, 14, 17) comprises a bulb (3) surrounding a light source (4) and a lamp base (2) arranged at an end of the bulb (3) and serving to support the lamp (1, 11, 14, 17) inside a reflector (20) of the headlight. At least one lens structure (7, 12, 15, 18) is present in or at an upper side (O) and/or lower side (U) of the bulb (3). This lens structure (6, 12, 15, 18) is constructed such that at least a portion of the light radiated by the light source (4) in the direction of a region of the reflector (20) close to the lamp base is redirected into a region of the reflector lying farther to the front.

Abstract:
A lighting arrangement for use in automotive front lighting and a method of producing such an arrangement are described. At least one LED lighting element 40 is provided for emitting light. A collimator 10 is provided for forming an emission pattern of the emitted light, which is subsequently projected by a secondary optic arrangement 42. The collimator 10 comprises a cutoff reflector surface 18 with a front edge 30 and a back edge 32. The back edge 32 is located adjacent to the LED lighting element 40. The front edge is spaced from the back edge 32 in a depth direction X, A. The front edge 30 is arranged as a shielding edge for forming a light/dark cutoff in the emission pattern. First and second lateral reflector surfaces 26a, 26b are arranged opposite to each other adjacent to the LED lighting element 40. The front edge 30 of the cutoff reflector surface 18 is arranged within a focal area of the secondary optic arrangement 42. For providing a beam pattern well suited for automotive front lighting, the first and second lateral reflector surfaces 26a, 26b extend further into the depth direction A, X than the cutoff reflector surface 18.
Abstract:
The invention relates to a lamp (10) and a vehicle headlight. The lamp (10) comprises a discharge vessel (16) with electrodes (20) arranged at a distance for creating an arc discharge. The envelope (22) has cylindrical shape with a cylinder wall extending straight in longitudinal direction. A reflective barrier (28) is arranged at least partly sur rounding said discharge vessel for reflecting light emitted from the arc discharge. To obtain an optimally focused reflection, the discharge vessel (16) is configured such that the arc (50) is essentially straight. The reflective barrier (28) also extends straight in longitudinal direction.
Abstract:
The invention relates to a compact incandescent lamp with an integrated reflector, comprising at least a lamp bulb, on one part of the surface of which the reflector is applied as a reflective layer and another part thereof is a light output window, an incandescent element, which is arranged in a defined way in the lamp bulb and is positioned in a defined way with respect to the reflective layer, wherein at least the part of the lamp bulb which carries the reflective layer is non-axisymmetric and/or a part of the light output window is asymmetrically shaped, so that the visible light which the lamp can generate illuminates a region of space non-axisymmetrically.
Abstract:
The invention relates to a lamp for motor vehicles that at least comprises a first incandescent filament that is intended to produce a light beam having a light/dark cutoff line, the incandescent filament having associated with it for this purpose a shielding cap to restrict the light emitted to a given angular range. The shielding cap (4) has at least one opening that is intended to produce a light beam above the light/dark cutoff line, with at least part of this light beam, which light beam passes through the said opening, not passing through and/or passing through a color filter.
Abstract:
In a lighting device with at least one continuous OLED layer (4) with a first electrode layer (5), a second electrode layer (6) and a plurality of optical collimating means, the second electrode layer (6) is only in electrical contact with the OLED layer (4) within spaced sections (6a), arranged within acceptance angles of the collimating means. Such a lighting device can be manufactured efficiently and is highly energy- efficient.
Abstract:
The invention relates to a lamp for vehicles with at least one main light source (2) which in the active operating state of the lamp emits primary light, with at least one light outlet opening (6) and with at least one translucent body (3) arranged in the beam path of the primary light, where into the translucent body or bodies (3) in the active and/or inactive operating state of the at least one main light source (2) can be coupled also secondary light which is emitted by at least one secondary light source (5), and the secondary light can be coupled into the translucent body (3) not parallel to the beam path of the primary light.
Abstract:
A lamp (10, 11) for a motor vehicle headlight is described. The lamp (10, 11) comprises a quartz bulb (3, 12, 17) narrowly enclosing a light source (1, 2) and possibly an outer bulb (4) surrounding said quartz bulb (3). Negative lenses (7, 8, 14, 15, 16) extending in the direction of a longitudinal axis (L) of the lamp (10, 11) are present in or at the two lateral surfaces (6, 13) of the quartz bulb (12, 17) and/or of the outer bulb (4). These lenses (7, 8, 14, 15, 16) are designed such that the light source (1, 2) is optically reduced in size in at least one direction.
