摘要:
An instrument cluster, in particular for a vehicle, has a dial with a plurality of graphic areas, which are backlit by a device provided with at least one light source, with a front light-guiding element having a front face at least partially covered by a back surface of the dial, and with a rear light-guiding element; the latter has a receiving portion facing said light source and a transmitting portion, which transmits and guides the light received by the receiving portion and is spaced apart from and faces a rear face of the front light-guiding element; the rear face of the front light-guiding element has an optical compensation system, having curved convex or curved concave lens surfaces, for varying the intensity of the light transmitted from said transmission portion to the different graphic areas.
摘要:
Die Erfindung betrifft ein Leuchtmosaik (10) mit einer Vielzahl lichtdurchlässiger Mosaikteile (11), insbesondere transparenter und/oder transluzenter Mosaikteile (11), wobei die Mosaikteile (11) relativ zueinander befestigt sind. Es weist außerdem eine Beleuchtungseinrichtung zur Hinterleuchtung der Mosaikteile (11) auf. Das Leuchtmosaik (10) zeichnet sich dadurch aus, dass die Mosaikteile (11) in Durchbrüche (13) eines lichtundurchlässigen Mosaikrahmens (12) eingesetzt sind. Außerdem ist ein Verfahren zur Herstellung eines Leuchtmosaiks (10) beschrieben. Ein Computerprogrammprodukt und eine Datenverarbeitungsanlage zur Durchführung des Verfahrens sind ebenfalls beschrieben.
摘要:
Disclosed are an illumination unit and a display apparatus using the same. The illumination unit includes first and second reflectors (200,300), and at least one light source module (100) placed between the first and second reflectors (200,300). The second reflector (300) ncludes a bottom plate (310), first lateral plates (320a)arranged to face each other in a first direction of the bottom plate(310), second lateral plates (320b) arranged to face each other in a second direction orthogonal to the first direction, a groove (110) formed in at least one of the second lateral plate (320b) and the bottom plate(310), and at least one hole formed in the groove (110).
摘要:
An LED light module for illuminating a target plane is provided. The LED light module (110,130) includes a first LED source, a second LED source disposed adjacent the first LED source, a first lens (124) covering the first LED source, and a second lens (126) covering the second LED source. The first lens (124) is configured to direct first light beams emitted from the first light source to the target plane (140). The second lens (126) is configured to direct second light beams emitted from the second light source to the target plane (140). At least one of the first and second lenses is shaped to have an asymmetrical profile. A backlighting system and a fixture incorporating the LED light module are also provided.
