A vehicle lamp includes a light source that shines a laser beam and a laser scanning unit that has a single or plurality of acousto-optic devices, and the laser scanning unit can control an angle at which a laser beam that is incident on the acousto-optic devices is deflected. The vehicle lamp is strong enough to deal with vibrations and withstands the application to a motor vehicle.

A vehicle lamp illuminating apparatus with ability for implementing various illuminating light patterns is constructed by a lens, a circuit board, a plurality of light emitting diode (LED) light sources disposed on the circuit board and distributed in an array, and a reflection structure disposed between the plurality of LED light sources and the lens. The LED light sources are transversely arranged in an upper row and a lower row. The reflection structure has a plurality of reflection mirror sets each disposed in one-to-one correspondence with two LED light sources that are vertically opposite to each other. Luminance of one or more local areas of an illuminating light pattern can be adjusted, thus implementing various illuminating light patterns and meeting a self-adaptive requirement of a headlamp.

A luminous motor-vehicle module intended to generate a light beam that projects forward an image. The image comprises at least one horizontal row of pixels. The luminous module is arranged so that a first pixel of the horizontal row of pixels comprises a lower end and/or an upper end that are/is vertically offset with respect to a lower end and/or an upper end of a second pixel of the same row, respectively.

An automotive lighting system (41) includes an automotive lamp having an LED array (14) and a lens (34). The lens (34) images a square field of illumination (101) into rectangular field of illumination (48) to support adaptive front lighting in an automotive environment (28). The lens (34) includes light-transmissive first, second, and third regions (64, 66, 68), and a baffle (70) adapted to obstruct light from spreading between the light-transmissive first, second, and third regions (64, 66, 68). The baffle (70) is disposed between the LED array (14) and light receiving surfaces (98, 104, 110) of the light-transmissive first, second, and third regions (64, 66, 68). The lens (34) enables imaging of an approximately rectangular field of illumination (48) from a single chip (12), reducing cost and cooling needs of adaptive front lighting systems.

An illumination device for a vehicle includes: plural light sources that are disposed so as to be lined-up in at least one line, and that illuminate light; a light-blocking member having an opening portion onto which light illuminated from the light sources is incident; and a projecting lens that emits, toward an object, light that has passed through the opening portion of the light-blocking member and has been incident on the projecting lens.

A lighting device includes: a liquid crystal element having electrode pattern including a first portion and a second portion; drive circuit connected to the electrode pattern; polarizer disposed in front of the liquid crystal element and separated from the liquid crystal element in optical axis direction; analyzer disposed at rear of the liquid crystal element, and separated from the liquid crystal element in optical axis direction, wherein the polarizer and the analyzer constitute crossed Nicol polarizers; light source for supplying lights to the liquid crystal element within a predetermined incident angle range; and projection optical system projecting lights transmitted through the liquid crystal element forwardly; wherein the polarizer and the analyzer locally overlap with the liquid crystal element in projection normal to the liquid crystal element, and when the light source is turned on, the drive circuit supplies drive signal to the first portion of the electrode pattern which applies or releases voltages in compliance with circumstances, and supplies drive signal to the second portion of the electrode pattern which continuously applies voltage, lights transmitting through the first portion of the electrode pattern and projecting forward transmit both the polarizer and the analyzer, and lights transmitting through the second portion of the electrode pattern and projecting forward include components which do not transmit at least one of the polarizer and the analyzer.

Some embodiments include a memory array having a series of bitlines. Each of the bitlines has a first comparative bitline component and a second comparative bitline component. The bitlines define columns of the memory array. Memory cells are along the columns of the memory array. Capacitive units are along the columns of the memory array and are interspersed amongst the memory cells. The capacitive units are not utilized for data storage during operation of the memory array, but rather are utilized for reducing parasitic capacitance between adjacent bitlines.
