The present invention is directed to a novel illuminated address sign assembly comprising a frame having an open front side, an open rear side, a top side, a bottom side, a left side, and a right side, forming an enclosure; an address plaque can be coupled to the open front side of the frame, while the open rear side can be provided with an opaque plaque. The address plaque comprises of an opaque indicia, representing the address, superimposed on a surface of a translucent backlit panel. The novel illuminated address sign can be further provided with a light sensor and GPS system.

An optical element includes a rectangular light guide plate, a light source setting portion, a parallel light lens group, and a total reflection lens group, disposed between the parallel light lens group and the first side surface, a part of the parallel light from the parallel light lens group is subjected to total reflection at least once to form a first parallel light parallel to the front surface, and the first parallel light enters the first side surface to make the second side surface emit light; another part of the parallel light from the parallel light lens group is totally reflected at least twice to form a second parallel light oblique to the front surface, and the second parallel light enters the first side surface to make the front surface emit light.

A caution device and a display device are used to draw attention to either a hazardous area, e.g., a construction zone, or a desired event, e.g., a grand opening. The devices are visible during daylight but are also equipped with LEDs to illuminate during twilight, dark, and inclement weather. The devices are preferably reusable.

A reflective-ink lighting assembly includes a light transferring medium, a reflective-ink marking in the light transferring medium, and a light source adapted to insert light into the light transferring medium. In a lit state, light from the light source propagates through the light transferring medium by total-internal reflection. As propagated light reflects off the reflective-ink marking, some light exits through a faade of the light transferring medium to produce an illuminated marking. In an unlit state, the reflective-ink marking remains visible due to ambient light reflecting off the reflective-ink marking.

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.

A curved display device including: a support frame having a curved shape; and a display panel disposed on the support frame and having a curved shape. The support frame is curved into a shape of an arc of a sector, and a first side surface of the support frame is parallel to a first radius of the sector.

The present disclosure is directed to an illuminated emblem assembly coupled to a steering wheel assembly and a method of assembling the same. The illuminated emblem assembly includes a conductive plate having a generally U-shape and formed from an electrically conductive material, a light source coupled to a PCB which is coupled to the conductive plate such that an electrical signal is provided to the light source from the vehicle control system via the PCB. The emblem assembly includes a base disposed on a top surface of the conductive plate also having a generally U-shape where the base includes an opening adjacent the light source for directing light emitted from the light source towards a U-shaped volume defined by a top surface of the base. Light is transmitted from the light source towards the user through an outer cap being disposed over the base.

An illumination structure for an electronic device is described. The electronic device includes a housing mounted on a printed circuit board. The housing has a plurality of light pipes and at least one separator disposed therein. The at least one separator is positioned between adjacent light pipes of the plurality of light pipes.

A face-lit waveguide illumination system employing a planar sheet of an optically transmissive material. A strip of side-emitting LEDs is positioned adjacent to a major surface of the planar sheet and optically coupled to the planar sheet. The planar sheet is configured to guide light using optical transmission and total internal reflection. Light extraction features located along the prevailing path of light propagation extract light from the planar sheet and emit the light towards a surface normal direction.
