An optical module includes a transmitter configured to pass light from a light source; an emitter integrally formed with the transmitter, and configured to emit light that has passed through the transmitter to outside of the optical module; and a converter covering at least a portion of the emitter, and configured to change a wavelength of light that has passed through the transmitter such that light emitted from the converter and light emitted from the emitter have different wavelengths.

The present invention aims to provide a luminescent curved glass which, despite being curved with a small radius of curvature, can provide a clear display on its entire surface when irradiated with light, and curved digital signage including the luminescent curved glass. Provided is a luminescent curved glass including a laminate including a transparent plate having a radius of curvature of 3,000 mm or lower and a luminescent sheet, the luminescent sheet containing a thermoplastic resin and a luminescent material that emits visible light having a wavelength of 380 to 750 nm under excitation light.

The face mask with temperature display is a filtering face mask with an integrated temperature display for displaying a measured temperature of the wearer. The face mask includes a filtering sheet having opposed front and rear faces, and at least one strap attached to the filtering sheet for securing the filtering sheet over a portion of a wearer's face in a manner similar to that of a conventional filtering face mask. A visual display is secured to the front face of the filtering sheet and a temperature sensor is secured to the rear face of the filtering sheet. The temperature sensor is in communication with the visual display, such that the visual display can display the measured body temperature of the wearer.

An apparatus comprising an illumination device and an illuminatable structure. The illuminatable structure comprises a laminate material having an opaque first side layer, a light transmitting middle layer, and an opaque second side layer. The illuminatable structure also has a light display area where the light transmitting middle layer is exposed. The illumination device emits light into the light transmitting middle layer of the illuminatable structure, and the light transmitting middle layer transmits the light to the light display area so that the light display area becomes illuminated.

Electrical equipment includes a badge positioned over a hole of the housing, the badge comprising a first portion made at least of a first material that is transparent or translucent to visible light, and a second portion made at least of a second material that is opaque to visible light and transparent or translucent to infrared light, the first and second portions forming respectively a pattern and a background distinct from the pattern on an outside surface of the badge; an emitter arranged to emit visible light signals through the badge so as to illuminate the pattern without illuminating the background, and a receiver arranged to receive infrared communication signals emitted by a device that is distinct from the electrical equipment and passing through the badge.

A system and method are disclosed for a lamp that includes a unit having a slit. The slit receives various inserts that allow the lamp to adapt in appearance for changing the décor of a room and/or provide information to a user in proximity to the lamp.

A container sleeve apparatus includes an arcuate or cylindrical body that can be positioned on a cylindrical or conical container, such as a tumbler, cup, can or bottle. A transparent or translucent insert section that can be releasably attached to the sleeve body. The sleeve body can be made of a non-slip, elastic material, such as neoprene rubber. The insert section can be made of plastic and can include a logo printed or engraved thereon. The apparatus can include a light emitting device that illuminates the transparent/translucent insert section.

A display unit for a passage control device, having a housing that has a front side, a rear side and an encircling circumferential side connecting the front side and rear side to one another. A display surface is integrated in the front side of the housing. The housing has an optical signaling apparatus that consists of front and rear light bands that are able to be actuated by a computing unit of the passage control device. The front light strip is arranged between the front and circumferential sides and the rear light strip is arranged between the rear and circumferential sides such that the front light strip is visible in a plan view of the front side and the rear light strip is visible in a plan view of the rear side.
