  • the power electronics include e.g. a power supply.
  • the device carrier may be designed as a sheet metal part or as an extruded profile and accordingly have axially open end faces.
  • end caps may be provided, which are axially attached to one of the axial end faces of the device carrier.
  • a “rectilinear body” as used herein means a body having a longitudinal central axis extending coaxially with a straight line.
  • elongated body is meant in the present context a body having a length measured in a longitudinal direction of the body that is greater than a height and width measured in a transverse direction of the body. In particular, the length of such elongated body at least twice as large, preferably at least ten times as large as a width and a length of the body.
  • LED stands for light-emitting diode. In the present context, the term LED also OLEDs understood, where OLED stands for organic LED.
  • an LED luminaire which has a plurality of illumination modules, each illumination module having a plurality of illumination units includes.
  • the respective lighting unit is designed to be rectilinear and oblong and comprises a rectilinear and elongated device carrier, which has at least one holding region on its front side, in which at least one printed circuit board is arranged, which carries a plurality of LEDs.
  • a power electronics is provided, which is arranged on a rear side of the device carrier, which is connectable to an external electrical power supply and which is electrically connected in a suitable manner with the respective board.
  • at least one end cap is provided, which is mounted axially on an axial end face of the device carrier.
  • a power supply cable via which the respective power electronics are supplied with electrical energy, is guided axially through one of the end caps to the outside.
  • the present invention is concerned with the problem of providing for such a lamp an improved embodiment, which is characterized in particular by a simplified manufacturability.
  • the invention is based on the general idea of equipping at least one end cap of the lamp or of the device carrier with at least one cable channel, through which at least one of the cables is passed.
  • the proposed construction is advantageous in several respects.
  • this design leads to the cables on the respective front side of the device carrier of the front are led to the back, so the front side of the equipment carrier over and no longer through the equipment carrier. Accordingly, can be dispensed with a passage opening for passing the cable through the equipment carrier. In that regard, simplifies the production of the device carrier.
  • such an end cap usually consists of a plastic, so that a passage of the cable through the end cap causes an efficient electrical insulation, so that the risk of direct contact between the respective electrical conductor of the cable and the equipment carrier is reduced. Furthermore, the risk of injury to the electrical insulation of the respective cable when passing through the respective cable duct is reduced, since the end cap, which is usually made of plastic, has no or only a slight abrasive effect with respect to the electrical insulation of the respective cable, as a rule also made of plastic.
  • the respective cable channel can in particular be spaced transversely to the longitudinal direction of the device carrier from wall sections of the end cap, which engage over the device carrier at the end face.
  • the respective cable channel may have a channel region with a closed cross-section in the circumferential direction between a first end open to the respective holding region and a second end open towards the rear side of the device carrier.
  • the open inner cross section of the channel region is preferably larger than an outer cross section of the respective cable. If only one cable is passed through the respective cable channel, is the Internal cross-section of the channel area a maximum of two times or a maximum of five times the outer cross-section of the respective cable.
  • the respective end cap may have a separate cable channel for each cable.
  • at least two separate cables are used to separately connect a positive pole and a negative pole of the board to corresponding terminals of the power electronics.
  • the respective cable channel may have in its cross section a push-through area and a fixing area, wherein the two areas openly merge into one another.
  • the push-through region can expediently be geometrically shaped such that the respective cable can be pushed through the cable channel relatively easily in the push-through region.
  • an inner cross section of the push-through region is slightly larger than an outer cross-section of the respective cable.
  • the fixing region can be suitably shaped such that the respective cable arranged therein is fixed to the end cap with a holding force which counteracts pulling out of the cable from the cable channel.
  • an inner cross section may be slightly smaller than the outer cross section of the respective cable. The respective holding force can be conveniently generated by frictional engagement.
  • the respective cable can thus be passed through the respective cable channel in a particularly simple manner through the push-through region. Subsequently, the cable can be transferred from the push-through area into the fixing area through the open transition between the push-through area and the fixing area. In the fixing area, the desired fixation of the cable then takes place on the end cap.
  • the push-through region may have a circular arc-shaped inner circumference.
  • the circular arc-shaped inner circumference extends in a circumferential direction from one end to the other end of the transition between push-through region and fixing region.
  • the fixing region may have an inner circumference converging with increasing distance from the push-through region.
  • the fixing region may have a substantially triangular inner circumference.
  • Such an embodiment of the fixing region causes pulling on the cable acting in the pulling direction Abuse forces pull the cable into the converging inner circumference of the fixing, whereby the holding forces generated in the fixing, acting between the cable and end cap holding forces are increased.
  • a transition between push-through region and fixing region may have barb-like projections which favor an adjustment of the cable from the push-through region into the fixing region and counteract a return adjustment of the cable from the fixing region into the push-through region.
  • the projections secure the cable transferred to the fixing area within the fixing area.
  • the fixing region may face the front side of the device carrier, while the push-through region is remote from the front side of the device carrier.
  • the respective end cap may have axially projecting outer walls as well as axially projecting inner walls.
  • the outer walls are adapted to an outer contour of the device carrier, while the inner walls are adapted to an inner contour of the device carrier.
  • the device carrier is an extruded profile, which may preferably be configured as a hollow chamber profile and accordingly has at least one closed in the circumferential direction of the hollow chamber.
  • the outer contour of the device carrier runs around the outside of the hollow chamber profile, while the inner contour of the device carrier rotates inside along the hollow chamber profile.
  • the outer walls and the inner walls can be coordinated so that adjusts a clamped action between the end cap and the equipment carrier in the mounted state.
  • inner walls and outer walls may have a decreasing distance in the insertion direction from each other, whereby a clamping action between the outer walls and the inner walls on the one hand and the circumferential wall of the inserted therein equipment carrier on the other hand can be achieved.
  • the outer walls are thicker, so have a greater wall thickness than the inner walls.
  • the inner walls can deform more elastic when plugging than the outer walls, whereby a visually high-quality outer contour for the lamp is maintained overall.
  • the respective cable channel may have a lateral recess open to the respective holding region at an end associated with the respective holding region.
  • This recess simplifies the laying of the respective cable, as it allows the respective cable to be inserted laterally into the cable channel.
  • the recess may for example be configured U-shaped.
  • the recess may converge with respect to its open end to create a clamping action there for the respective cable.
