A current-generated photo-luminescent hybrid sign is provided that includes one or more light emitting elements within a channel in the frame to evenly distribute light, while at the same time energizing a photo-luminescent glow material in case of power outage. A method of use of the sign is also provided.

In a lighting arrangement, in particular for escape route lighting, comprising a light source and an optical element assigned to the light source, said optical element being designed to emit asymmetrically the light emitted by the associated light source, the optical element can be positioned in different ways.

The present disclosure relates to a function display for selectively displaying symbols representing switching states for a motor vehicle including a light guide stack of at least two transparent or translucent, planar light guides arranged in an overlaid manner in a stacking direction, which are spaced apart by a transparent or translucent layer including a material that is optically thinner compared to the adjacent light guides so that the light guides have a main surface facing towards an observer and a main surface facing away from the observer that faces towards a light guide which is most closely adjacent in stacking direction; at least one light source per light guide arranged to couple light into the respective light guide via an end face; wherein one light-refractive and/or light-scattering microstructured portion per light guide, which is provided in or on the light guide, is provided for generating a symbol display.

An illuminated vehicular sign is provided including a vehicle and luminescent planar sheet. The luminescent planar sheet is constructed to provide illuminated alpha-numeric characters which are mounted to the horizontal planar surfaces of a vehicle. The alpha-numeric characters are mounted substantially horizontally so as to be seen from the air such as by helicopters or planes. The illuminated vehicle sign includes a switching system electrically connected to the luminescent planar panels for selectively controlling the transfer of power from said power source to the luminescent planar panels. The switching system including one or more adjustable variable resistors electrically connected to the luminescent planar panels for allowing one to selectively adjust the wattage provided to them.

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.

A combination signboard having the characteristics of low cost, ease of fabrication, maintenance and replacement is disclosed to include a signboard body having multiple through holes, multiple display devices detachably mounted on the signboard body, each display device including a mount having a recessed portion and multiple countersunk holes located in the recessed portion, a light guide plate positioned in the recessed portion, a light source module sandwiched between the light guide plate and the recessed portion and connection members made in the form of a screw bolt and respectively mounted in the countersunk holes of the mount, and locking members made in the form of a screw nut and respectively threaded onto the screw bolt-shaped connection members to detachably lock the display devices to the signboard body.

An LED module is disclosed, which includes one or more LED light sources and one or more lenses. Each lens includes a lens body. The lens body includes an inner cavity having an incident surface, an emergent surface, and a reflective surface extending between the incident surface and the emergent surface for providing total internal reflection. One LED light source is situated in the inner cavity. Light emitted from the LED light source is transmitted by the incident surface. At least portion of transmitted light by the incident surface is reflected by the reflective surface to the emergent surface so as to provide a narrow light beam angle perpendicular to a length direction of the LED module. The emergent surface has a plurality of micro structures for enlarging a light viewing angle in the length direction. A sign box using one or more LED modules is also disclosed.
