An emblem for a vehicle comprises: (a) a light source configured to emit visible light; (b) a cover assembly disposed over the light source, the cover assembly having an inner surface, an outer surface, and a transparent portion that is transparent to the visible light, the visible light being incident to the inner surface, and the visible light that the light source emits transmitting through the transparent portion out of the outer surface to an external environment beyond the emblem; and (c) one or more surface relief patterns disposed on the cover assembly, the one or more surface relief patterns configured to manipulate (i) the visible light that the light source emits, (ii) visible light from the external environment, or (iii) both (i) and (ii).

A display device includes a translucent windscreen, particularly the windscreen of a motor vehicle, a narrow-band light source that emits light into the windscreen via an edge thereof, and a periodic structure formed in the windscreen that bends the light from the light source toward the eye of a driver.

An illuminating panel includes a support holding an integrated illumination. The integrated illumination is an illuminating textile including woven optical fibers coupled to light sources. The optical fibers emit light under an angle suitable for enlightening an adjacent surface substantially perpendicular to the plane of the illuminating panel.

A domestic appliance, in particular a domestic refrigeration appliance, has a lamp for illuminating a recessed handle of a door. The recessed handle has a recess. The door has a light-guide element in the recess and the door also has a light source for illumination into the light-guide body at least on a front end of the light-guide body.

A lighting glazing includes a first sheet of glass of refractive index n1 with a first main face, a second main face and a rim; a transparent polymer film in adhesive contact with the second main face of the first sheet, the film having a refractive index n2<n1; a light source positioned facing the rim of the first sheet of glass, wherein an area of the second main face of the first sheet of glass is provided with a reflecting relief or else is covered with a transparent flat structure, of refractive index n3 greater than or equal to n1, provided with a reflecting relief.

Devices used for workspace illumination include, for example, a panel and a solid-state based optical system arranged inside an enclosure of the panel. The panel can be a cubicle divider. In one aspect, an illumination device includes a mount; a panel including a first face and a second opposing face. The panel is vertically supported by the mount along a horizontal dimension of the first and second faces. Further, the panel forms an enclosure between the first and the second face. Additionally, the illumination device includes a first luminaire module arranged in the enclosure and configured to output light in a first output angular range. The light output in the first output angular range has a prevalent propagation direction with a vertical component towards a first target area.

Techniques are provided for a high dynamic range panel that includes an array of light sources (202,203) illuminating a corresponding array of light guides (204, 206). A light source (202) of the array illuminates a first light guide (204). The light source directly underlies, such as in a cavity (208), a second light guide (206) that is adjacent to the first light guide. The light source (202) does not extend below a bottom side (214) of either the first light guide or the second light guide to reduce thickness of the panel. The light source (202) and the first light guide (204) can be integrated as a tile assembly. Alternatively, the light source (202) and the second light guide (206) can be an integrated tile assembly. In a specific embodiment, the light source emits a blue or ultra-violet light, which is converted by quantum dots to a different color.

A glass panel includes a first glass substrate, a second glass substrate, a spacer profile at the periphery of the glass panel between the first and the second glass substrate. There is an intermediate substrate in the intermediate space between the first and the second glass substrates, the substrate having a first coefficient of thermal expansion, and means to maintain the intermediate substrate within the intermediate space. The panel also includes a second profile, having a second coefficient of thermal expansion, positioned facing the inner face of the spacer profile within the intermediate space between the first and second glass substrates of the glass panel. The second profile carries the means to maintain the intermediate substrate within the intermediate space. A difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion is less than or equal to 20%.

Provided is a lighting device, comprising: a light source module comprising: at least one light source disposed on a printed circuit board; and a resin layer disposed on the printed circuit board so that the light source is embedded; a light reflection member formed on at least any one of one side surface and another side surface of the resin layer; and a diffusion plate having an upper surface formed on the light source module, and a side wall which is integrally formed with the upper surface and formed to extend in a lower side direction and which is adhered onto the light reflection member, wherein a first separated space is formed between the light source module and the upper surface of the diffusion plate, whereby flexibility of the product itself can be secured, and durability and reliability of the product can be also improved.

A circuit module is provided, including: a substrate, having a PCI-E or PCI strip, the PCI-E or PCI strip for being inserted into and electrically connected with a PCI-E or PCI slot; at least one LED, disposed at a side of the substrate opposite to the PCI-E or PCI strip, electrically connected with the PCI-E or PCI strip; a light guide member, being pervious to light, at least corresponding to the at least one LED.
