摘要:
The present invention relates to an LED lighting device system for a vehicle which prevents erroneous lighting of the LED lighting device due to leakage current at the operation switch. An LED lighting device system (80) for a vehicle is provided with an LED lighting device (X) having an LED light source (84), an operation switch (32) for lighting and extinguishing the LED light source (84), and a power source (66) that is connected to the input side of the operation switch (32) and feeds electrical current to the LED light source (84). The LED light device system (80) for a vehicle has a switching element (100) capable of blocking electrical current flowing to the LED light source (84) and a detection unit (104) that detects voltage on the output side of the operation switch (32) and causes the switching element (100) to block the electrical current.

Die Erfindung betrifft eine Leuchtvorrichtung (1) für ein Fahrzeug (20). Die Leuchtvorrichtung (1) umfasst einen biegbaren, an einer gekrümmten Oberfläche befestigbaren Leuchtmittelträger (3) und wenigstens ein auf dem Leuchtmittelträger (3) angeordnetes Leuchtmittel (5, 7), das zur Aussendung von Licht aktivierbar ist.
摘要:
The present invention describes a dynamic warning system suitable to indicate a dangerous area next to a vehicle (1), in particular an area of a road surface in the blind angle (10) of a driver. By illuminating the surface the soft targets (4) will be aware and alerted that attention has to be paid. In practice the illuminated area shall have a sufficient extent such that when the vehicle turns, any object, and in particular any soft target outside the illuminated zone (20) shall be (relatively) safe from coming into contact with the moving vehicle. The warning system comprises: • - a housing suitable to be fastened to or integrated into an exterior surface of a vehicle; • - a light source (5; 30) arranged inside said housing, said light source (5; 30) being capable of emitting sufficient light to illuminate the road surface; • - means (7,11,12;21) for splitting said emitted light into a plurality of distinct light beams, which when projected onto the road surface indicates an area (14;24); • - means for moving the light source relative to the means for splitting the emitted light or vice versa, thereby creating a dynamic warning on said road surface.
摘要:
A wireless, removable vehicle signaling control and illumination apparatus which may be for use on vehicles. The system may utilize a miniature digital radio transceiver inside a lamp housing to provide wireless control of the lamp. The signaling system may provide a signaling solution for a user which does not require alteration or modification of the vehicle. Such a system may improve conspicuity, safety, and illumination capabilities of the vehicle.

Novel arrangements are disclosed that provide for replacement of printed circuit boards useful in regulating current for LEDs. In one embodiment, a conductive track is disclosed that forms a pattern for placement of electrical components. The track can be made out of any suitably conductive material and may be stamped, cut, or formed depending on the material type. The conductive track can conduct both electricity and heat. Portions of the conductive track can be removed creating a gap. Electrical components can be placed along the conductive track spanning the gap to create a circuit path. Other embodiments include wiring harnesses that contain embedded electrical components. The harnesses may occupy less space than some embodiments of the conductive track. An electrical connector may be provided to allow easy replacement of the LED.

摘要:
An automotive lighting system (20) is described with a signal emitting device (30) installed in a lamp socket (18). The lamp socket (18) is connected to a lighting connection (16) of a vehicle (10). The signal emitting device (30) emits a signal if the lighting connection (16) is energized. A lighting module (24) is connected to an electrical power supply (28) of the vehicle (10). The lighting module (24) comprises a receiver (42), a control unit (45) and a light source (22). The control unit (46) is disposed to operate the light source (22) in a first mode if a signal is received in the receiver, and in a second mode if the signal is not received.

摘要:
An optically adjustable light module, such as a daytime running lamp of a motor vehicle, includes a light source (e.g., including an LED) which is rotatable about a rotational axis and has an optical axis. An arm is connected to the light source such that movement of the arm enables rotation of the light source and adjustment of the optical axis.
