Abstract: A method for transmitting control commands in a system (100) of units (L1-L18) in a distributed arrangement, for example in a lighting system having luminaires in a distributed arrangement, involves at least some of the units (L1-L18) sending a received control command again in order to ensure that the control command is forwarded to all units (L1-L18). The control command contains a piece of information regarding an already past command transmission time, wherein each unit (L1-L18) takes the command transmission time that a received command contains as a basis for determining an individual waiting time (TTLind), after the expiry of which the command is executed by the unit (L1-L18).

Said lighting system comprises at least two lamp units (24-31), each of which (24-31) or a defined group of which (24-31) is assigned to a different space, especially a shelf surface. The lighting system (10) further comprises a control unit for controlling the lamp units (24-31), to each of which (24-31) or to each defined group of which (24-31) a different lamp address is assigned. The lamp address is linked to a product association that is unambiguously associated with a product (40, 41, 42) located in the assigned space. The lighting system (10) also comprises a user interface (54) used for displaying the product associate and for selecting, by means of the displayed product association, the lamp unit (24-31) or defined group of lamp units (24-31) to be controlled. The invention further relates to a corresponding method for providing a lighting system (10) and locating a product.

Abstract: An optical element for influencing light emitted by a plurality of LEDs, which has a light entrance region for entrance of the light, and a light exit region situated opposite the light entrance region and serving for exit of the light. An arrangement for light emission comprising such an optical element and the LEDs are also disclosed. An axis (A) running both through the light entrance region and through the light exit region is defined by the shape of the optical element; the light exit region is subdivided by a ring-shaped indentation into a central middle region and an edge region arranged around the middle region. The light entrance region and the light exit region are shaped in such a way that, as viewed in a direction along the axis (A), they have an n-fold rotational symmetry, wherein n is a natural number greater than 2.

Abstract: A luminaire for generating direct lighting and indirect lighting including an LED light source for generating light and a light guide plate having a first main surface and a second main surface, which is connected to the first main surface marginally via a narrow side face, wherein the LED light source is arranged in such a way that the light is radiated into the light guide plate via the narrow side face and subsequently one part of the light is emitted for generating the direct lighting via the first large main surface. Furthermore, a reflector is provided, which is arranged adjacent to the second main surface, wherein the reflector has at least one light-transmissive region configured in such a way that a further part of the light is emitted for generating the indirect lighting via the second main surface through the light-transmissive region.

Abstract: A lighting device having a support element with an elongated receiving region which has a U-shaped cross-section and having a first limb of the U, a second limb of the U, and a connecting limb that connects the two limbs of the U. The lighting device further has an LED lighting module with at least one LED for generating light in order to emit a light of the lighting device, the LED lighting module being arranged on the support element in a retained manner. The lighting device further has a contacting element for supplying power to the LED lighting module. The connecting limb has a through-opening, the contacting element and LED lighting module being arranged so as to be connected in an electrically conductive and reversibly releasable manner such that the electric connection passes through the through-opening.

Abstract: The invention relates to a cover for a support arrangement of a strip light system, said support system comprising at least two elongate support rail elements which are arranged behind each other in the longitudinal direction. According to the invention, the cover is formed by an elongate shaped part on which several contact elements which are interconnected by means of at least one cable are arranged, and which are described to make contact by means of the light modules of the strip light system.

Abstract: The invention relates to a lighting-means carrier (5) for a strip-lighting luminaire, comprising: at least one lighting-means circuit board (30) having light-emitting diodes (33) that can be arranged thereon; and at least one heat sink (31) thermally connected to the lighting-means circuit board (30). In a central region, the lighting-means circuit board (30) is rigidly connected to the heat sink (31) in such a way that substantially no relative motion between the lighting-means circuit board (30) and the heat sink (31) is possible. In at least two further regions, the lighting-means circuit board (30) is connected to the heat sink (31) in a floating manner, the lighting-means circuit board (30) therefore being arranged on the heat sink (31) in such a way that the lighting-means circuit board can be moved in relation to the heat sink (31) outside of the central region. The invention further relates to a strip-lighting luminaire having at least one lighting-means carrier (5) according to the invention.
