The invention relates to an emergency luminaire (1) with a housing (2) accommodating a light source (3) and control means (4) configured to control light emission of the light source (3). The housing (2) is configured for attaching an emergency sign unit (5) to the housing (2) such that the light emitted by the light source (3) lights the emergency sign unit (5) when the emergency sign unit is (5) attached. The control means (4) is configured to determine whether the emergency sign unit (5) is attached to the housing (2) or not; and control the light emission of the light source (3) according to a first operation mode when no emergency sign unit (5) is attached to the housing (2), and according to a second operation mode when the emergency sign unit (5) is attached to the housing. The second operation mode is different from the first operation mode.

A symbolic display element comprised of light emitting device coupled to side emitting fiber is disclosed. This symbolic element is an information display when the side emitting fiber substrate with specific light conducting and emitting properties is coupled with the light emitting device and the light emission is controlled by any means or methods. A method for forming the substrate into a symbolic shape is disclosed. A method of coupling light emitting device to the substrate is also disclosed. A method for using a plurality of such symbolic elements as information display is also disclosed.

An illuminated address display for a building and residence having a housing with a front wall with an inclined upper portion and vertical lower portion, solar cells on the inclined upper portion and a group of small rectangular panels suspended from the lower portion of the housing. On the small rectangular housing there is an address identifier consisting of alphanumeric digits which disclose the address of the residence or building. The alphanumeric digits have segments which extend through the panels and are backlit by light emitting diodes which are mounted on a removable cover on the bottom of the housing. Inside of the housing are batteries and a solar charge controller to prevent overcharging of the batteries and an on/off switch.

A shelf illumination device (1) for illuminating a shelf board of a shelving system. The device (1) is mounted on a component such as the shelf board. An illumination unit (4) with a plurality of light source is attached to an illumination support (3) to illuminate at least one of the shelf boards. At least one partially transparent label holder (5) receives at least one label, a shelf marking or the like. At least one light guide (6) at least in sections extends between the illumination support (3) and the label holder (5). The light guide (6) is constructed and arranged so that a portion of light emitted by the illumination unit (4) is coupled into and propagates through the light guide (6) to at least partially backlight the label holder (5), whereas the remaining portion of the light emitted by the illumination unit (4) illuminates the shelf board.
