An industrial electronic apparatus includes a display panel that includes a design portion including a character or a graphic, and a light source provided behind the display panel. The display panel includes: a transparent plate having a back face located on the light source side and a front face located on a side opposite to the light source side; a light shielding portion that is located on the back face side of the transparent plate, covers a portion, of the back face, that does not correspond to the design portion, and includes a window that is formed at a portion, of the back face, that corresponds to the design portion, and a light diffusing portion that is located on the back face side of the transparent plate, and covers a portion, of the back face of the transparent plate, that corresponds to the design portion.

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 light reflecting assembly for a backlight module includes a cabinet and a light reflecting member. The light reflecting member includes a center reflecting part, four peripheral parts, and a tongue part. The peripheral parts at least partially form trapezoidal peripheral reflecting parts of the light reflecting member, respectively. The tongue part extend from an end edge of one of the peripheral parts towards an adjacent one of the peripheral parts. The tongue part at least partially overlaps with the adjacent one of the peripheral parts while the light reflecting member is attached to the cabinet. The end edge of the one of the peripheral parts is arranged to form a corner section of the light reflecting member at a corner portion of the center reflecting part while the light reflecting member is attached to the cabinet.

A concealed light fixture sign includes a flange having stencil openings formed therein that define a message. A container extends from a rear surface of the flange and provides light through the stencil openings. The container is configured to be installed completely within a recess behind a mounting surface with the flange positioned substantially flush with the mounting surface. Translucent inserts positioned within the stencil openings are removable to provide access to an interior of the container after installation of the light fixture sign.

[Object] To provide an illumination device that enables uniform illumination by preventing an air layer from intervening between an adhesive layer and a substrate through manual bonding of a reflection sheet, and a display device including the illumination device. [Solution] An illumination device includes a substrate including a wiring pattern, a plurality of light sources connected to the wiring pattern, an adhesive layer disposed on the substrate, and a reflection sheet bonded to the substrate with the adhesive layer interposed therebetween. The reflection sheet includes openings corresponding to the plurality of light sources. In a first direction, the reflection sheet is located between the substrate and light-emitting surfaces of the light sources. The substrate has an air vent in an area in which the wiring pattern is not disposed and the adhesive layer is disposed.

An invisible, light-transmissive display system with a light resistant material is provided. Substantially invisible holes penetrate through at least a portion of the light resistant material in a predetermined light-transmissive display pattern.

A display panel is attached to an appliance that includes first and second light sources, in which one of the first and second light sources is capable of being turned off when the other is turned on. The display panel basically includes a molded body, a front-side decorative layer, and a sheet-like member. The display panel is capable of individually illuminating a plurality of graphics, which is simultaneously molded and decorated, with light passing through a molded resin. In particular, a first graphic is illuminated in a first window by turning on the first light source, while a first back-side light-shielding region and a second front-side light-shielding region prevent a second graphic from being illuminated. The second graphic is illuminated in a second window by turning on the second light source, while a second back-side light-shielding region and a first front-side light-shielding region prevent the first graphic from being illuminated.
