A vehicle headlamp includes a light source, a projection optical member, a light deflector, and a tube shaped housing. The projection optical member projects light, which is incident on the projection optical member, ahead. The light deflector includes a plurality of optical devices that are arrayed. The optical devices are individually switchable between a first state and a second state. In the first state, the optical devices reflect light emitted from the light source to a direction other than a direction towards the projection optical member. In the second state, the optical devices reflect the emitted light towards the projection optical member. The light deflector is disposed inside the housing. The projection optical member is disposed in an opening portion of the housing. A first portion, of the housing, intersecting a path of a light beam incident on the light deflector is transparent.

A light device 1 for a motor vehicle comprising: at least one first aperture for air, and a first plug for the at least one first aperture, the first plug being movable between a closed position and an open position of the first aperture.

The light device thus makes it possible to achieve: efficient ventilation, when the plug is in the open position, particularly when the vehicle is moving, and relative obstruction to the ingress of dust and liquids, when the plug is in the closed position, particularly when the vehicle is stationary.

An antifogging agent composition which contains a copolymer (A), colloidal silica (B) and a solvent (C), wherein: (A) is a (meth)acrylate copolymer obtained from a monomer mixture which contains monomers (a-1) to (a-3); (C) contains water (C-1), a C1-4 monovalent alcohol-based solvent (C-2), a solvent (C-3) which has one or more functional groups per molecule selected from a ketone group, an ester group, two or more ether groups, a thioketone group and an amide group, and has a boiling point of 100-200 C., inclusive, and a glycol ether-based solvent (C-4) represented by general formula (5) (R.sup.10OR.sup.11OH); and the combined total of (C-1) to (C-4) relative to 100 parts by mass of the combined total of (A) and (B), and the mass ratios of (C-3) and (C-4) relative thereto, are specific amounts. Also disclosed is an antifogging article including an antifogging coating formed from the antifogging agent composition on a base material.

A camera unit is configured to capture an image of an outside area of a vehicle. A translucent cover covers the camera unit. A first air cleaner is configured to jet gas toward an area on the translucent cover located within an angle of view of the camera unit. The first cleaner is located above the area in an up-down direction of the vehicle.

An anti-fogging agent containing silica particles, a binder compound, and a silane coupling agent that is an acid anhydride or a dicarboxylic acid compound. An anti-fogging agent containing a synthetic product A obtained by reacting a silane coupling agent that is an acid anhydride or a dicarboxylic acid compound with a binder compound; and silica particles.

The invention relates to a fastening device for fastening a headlamp in a motor vehicle, having a first and a second fastening element, which are connected to one another by means of a latching connection, wherein the first fastening element and/or the second fastening element have a predetermined breaking point.

The invention relates to a cleaning device (20) for a lens glass (10) in particular of a vehicle, with an optically transparent lens glass (10), with a hydrophobic and dirt-repelling, optically transparent coating (25), which is applied on an outer side (11) of the lens glass (10), with at least one vibration element (21), which is coupled with the lens glass (10), wherein the at least one vibration element (21) can be activated by a control device (40), and with an optically transparent anti-fog device (30), which is arranged at an inner side (12) of the lens glass (10). Furthermore, a vehicle with at least one cleaning device (20) is specified within the scope of the invention.

A vehicle sensor device (1) includes an outer cover (12), a sensor unit (20) that transmits and receives an electromagnetic wave through the outer cover (12) and outputs a signal related to the electromagnetic wave incident on an inner side of the outer cover (12), a heater (30) that is provided in the outer cover (12) and heats a transmission region (AR) of the outer cover (12) through which the electromagnetic wave emitted from the sensor unit (20) passes, and a control unit (CO). The control unit (CO) outputs a detection signal of an object located outside the outer cover (12) based on the signal from the sensor unit (20) in at least a part of a period in which the heater (30) is OFF, and stops outputting of the detection signal in at least a part of a period in which the heater (30) is ON.

A vehicle headlight deicing film device includes a lamp assembly and a deicing film device is arranged in a housing of the lamp assembly. The deicing film device includes a microwave generator and a waveguide tube. The microwave generator generates and outputs a microwave. The waveguide tube guides the microwave output by the microwave generator out of a reflector of the lamp assembly and transmits the microwave to a lens of the lamp assembly. The microwave acts on the ice film on the outer surface of the lens, and the solid and hard state of the ice film begins to loosen, making it easy to separate from the lens.

An electric heating film includes a substrate and a first conductive mesh. The first conductive mesh is patterned on a side of the substrate in a first direction, and configured to generate heat under an energized condition. A plurality of breakpoints are distributed unevenly in the first conductive mesh. By appropriately configuring the distribution of the breakpoints in the first conductive mesh, the heating rate distribution of the first conductive mesh may be better adapted to specific application requirements.
