A light source is provided with a digitally addressable lampshade that includes a plurality of regions of controllable opacity. Systems and methods are described for controlling the digital lampshade. In an exemplary embodiment, an addressable lampshade effects a time-varying pattern of changes to the opacity of the regions to generate a lamp identification pattern. A lamp is identified from the patterns by a camera-equipped mobile device. The mobile device then causes the identified lamp to generate a position-determining pattern of light. The mobile device determines its own position relative to the lamp based on the pattern of light received by the camera. The mobile device then instructs the digital lampshade, according to user input, to allow illumination or to provide shade at the determined position of the mobile device.

The said moving image effect created by having at least one of the said 3 basic-parts project-assembly fit into or built-into or install to all kind of different light's housing construction of LED projection light for outdoor or-and indoor application(s) said LED light image or lighted patterns has moving, shaking, spin, rotating, vibration to get the desired moving or-and changing effect(s) and other unique features.

A microwave-sensor application for a light or electric device has a built-in microwave-sensor which can penetrate a wall, glass, building, garage door, or cement to detect over a 360 degree angle and predetermined vertical range. The microwave sensor can be used to activate a microwave-sensor application device or light device having an LED and/or laser for illumination or to provide an anti-theft alarm or warning.

A vehicular overhead console module includes a base portion configured to attach at an interior cabin portion of a vehicle. A light source is accommodated by the base portion and is electrically operable to emit light. A light transmitting panel is disposed at the base portion and includes an electrically dimmable medium. The electrically dimmable medium is adjustable at least between a first light transmission state, where the light transmitting panel has a first level of light transmissivity, and a second light transmission state, where the light transmitting panel has a second level of light transmissivity. The first level of light transmissivity is greater than the second level of light transmissivity. When the electrically dimmable medium is at the first light transmission state, light emitted by the light source passes through the light transmitting panel to illuminate at least a portion of an interior cabin of the vehicle.

The invention provides a lens comprising a plurality of imaging regions, each adapted to image a light source to generate a plurality of virtual light sources common to all imaging regions and distributed along a spatial path extending in a direction generally away from the lens. Each imaging region comprises a plurality of sub-regions for focussing the input light source to a corresponding plurality of focal points common to the imaging regions. The focussed light directed to the focal points sub-regions of each imaging region combines so as to form at each focal point a virtual light source. An optical deglaring plate comprising an array of conical optical structures is used with the lens.

A variable light beam is provided from a light source. The light source can be an LED light source or other source. The light source includes basic collimation optics, such as reflector or Fresnel lens, an electrically controllable LC device, such as a polydisperse LC film, in front of the incident spot light beam. Preferably the polydisperse LC film includes transparent flat uniform electrode layers. The LC device can be autonomous of the light source. The proposed solution provides a dynamically controllable, preferably polarizer-free and pixel-free, beam shape light source module including a controllable light beam control module and a light source module providing the initial light beam in a scanner light source, a camera flash, an architectural, automobile or industrial lighting device.

The present disclosure provides a pattern projecting lamp and a motor vehicle-in particular, a motor vehicle comprising a pattern projecting lamp. The pattern projecting lamp comprises an optical module configured to provide a projection light beam having a pattern, a support comprising a base and a rotary arm connected rotatably to the base, wherein the optical module is disposed in the rotary arm, and the rotary arm is provided with a light exit for the projection light beam to be emitted through.

A reflector unit may behave as a retroreflector to reflect light of a selected color. The reflector unit may comprise a first reflector having a first color, a second reflector having a second color, and a mask that either allows incoming light to reach the first reflector and not the second reflector or allows incoming light to reach the second reflector and not the first reflector. An active light unit may emit light of a particular color in response to receiving light. In this fashion, the active light unit may simulate the operation of a reflector. The reflector unit and the active light unit may operate on a bi-directional vehicle.

A lighting device comprises a light-emitting module with light-emitting elements, wherein the light-emitting elements are arranged adjacent to each other and are configured to emit light towards a light-emitting side. The light-emitting module is configured such that the light-emitting elements can be addressed partially independently of each other, such that some may be brought into a switched-on state while others are brought into a switched-off state. A top layer is disposed on the light-emitting module at the light-emitting side. Further comprising a switching material capable of a reversible change in transmittance for the light emitted by changing to a higher transmittance in regions where the top layer situated on light-emitting elements in the switched-on state or to a lower transmittance in regions of the top layer situated in the switched-off state. The invention further refers to methods for producing and operating a lighting device and using a lighting device.
