An electrical device for a vehicle includes a housing having an upper portion and a lower portion. An upper light source attaches to the upper portion and a light guiding element attaches to the upper portion to receive the upper light from the upper light source and direct outgoing light in a substantially uniform direction. A display attaches to the upper portion to receive the outgoing light for illumination of the display. A lower member couples with the lower portion. A lower light source attaches to the lower member. A collimator attaches to the lower member to receive incoming light from the lower light source and change directions of the incoming light to a collimated beam. A lens element attaches to the lower portion to direct the collimated beam at a target.

In one aspect, a back-lit digital photograph frame system is provided. A display assembly includes: a tray frame comprising a back surface of the display assembly as a backside enclosure; an optical acrylic block comprising a front surface of the display assembly; a light guide plate, wherein the light guide plate is located between a photographic print and a reflective backing paper, the photographic print, wherein the photographic print is located between optical acrylic block and the light guide plate, and a reflective backing paper, wherein the reflective back paper is located between the light guide plate and the tray frame, wherein the tray frame, the optical acrylic block, the light guide plate, the photographic print and the reflective backing paper are set in a vertical stack, and a base mount comprising an opening that receives the display assembly and holds the display assembly in a vertical position orthogonal to a receiving surface of the base mount, wherein the display assembly is held in place with a compression fit, and wherein the base mount further comprises a light emitting diode (LED) strip.

An illuminant comprising a transparent substrate layer with a first index of refraction, a connecting layer with a second index of refraction that differs from the first index of refraction, and a metallic, translucent layer, wherein the connecting layer is arranged between the substrate layer and the metallic layer, and wherein on the side facing the connecting layer the substrate layer comprises a plurality of decoupling structures suitable for decoupling light that propagates within the substrate layer from the substrate layer in the direction towards the metallic layer.

A system and method for controlling amount of light emitting from an illuminating screen including: a frame defining a space, a screen mounted onto a front side of said frame, a back plate mounted onto a back side of the frame, opposite the front side, at least one light source and a concealing element. The at least one light source is positioned within the space defined by the frame and is configured to illuminate the screen. The concealing element is located inside the space defined by the frame and is configured to block light from illuminating the screen. The amount of light emitting through the screen is controlled by a ratio between the area of the concealing element positioned in a section located between the at least one light source and the screen, and the total area of the section.

A face-lit waveguide illumination system employing a planar slab or plate of an optically transmissive material. A light source is optically coupled a linear optical element which is formed in or attached to a face of the waveguide and is configured to inject light at an angle permitting for light propagation by means of a total internal reflection. Light is propagated through the waveguide towards a predetermined direction in response to optical transmission and total internal reflection. Light extraction features located along the prevailing path of light propagation extract light from the waveguide and emit such light towards a surface normal direction.

Systems, methods, and devices for making a three-dimensional design are disclosed. The method includes generating a base layer with a three-dimensional feature by removing material from a starting block. Then a cover layer is generated with an opening having a shape that corresponds to the three-dimensional feature. The cover layer is coupled (e.g., adhered) to a first front surface of the base layer by inserting the three-dimensional feature into the opening. The three-dimensional feature extends past a plane defined by a second front surface of the cover layer such that a side surface of the three-dimensional feature is exposed. A light fixture is positioned adjacent to a back surface of the base layer, such that the three-dimensional feature is illuminated through the opening. A top surface of the three-dimensional feature is covered, such that light only transmits through the side surface of the three-dimensional feature, creating a backlighting effect.
