- the case bottom is made of aluminum and carries an LED board.
- the upper side of the housing is formed from a one-piece plastic part, which has webs inside, which may optionally also be reflective.
- the present invention provides a luminaire insert with a carrier element, on which a luminaire module and a plurality of reflector modules of the luminaire insert are arranged.
- the light-emitting module has at least one light-emitting means.
- the reflector modules are fastened to the carrier element and exert a contact force on the illuminant module in the direction of the carrier element.
- a force is exerted simultaneously on the carrier element by the attachment of the plurality of reflector modules to the carrier element, by means of which it is pressed in the direction of the carrier element.
- the luminous means module can lie directly against the carrier element.
- a further element in particular a heat-conducting foil, can be arranged between the luminous-element module and the carrier element.
- the contact force both the mechanical definition and the thermal connection of the lamp module is improved on the support element.
- a desired contact force can be set in this way, which causes the required mechanical stability and thermal connection and at the same time prevents mechanical damage to the lamp module.
- the luminous means module according to the invention clamped by the reflector modules to the support member so that it is securely attached to the support member even with a temperature-induced expansion.
- the separate design of the reflector modules can be dispensed with a painting or other processing of the support member to form light-guiding structures. This simplifies the manufacture of the luminaire insert. Due to the separate design of the reflector module and the carrier element, both can be optimized separately instead.
- the carrier element, the lamp module and / or the reflector modules are elongated.
- the carrier element, the lighting module and / or the reflector modules can be aligned parallel to one another.
- one or each of the reflector modules may extend along an entire length of the support member.
- the reflector modules may be made of a reflective material, have a reflective surface coating or be provided with one or more reflective elements.
- the reflector modules can be formed directly and / or diffusely reflecting.
- a reflective surface of the reflector module is planar.
- a reflective surface of the reflector module may be at least partially curved, in particular concavely or convexly curved.
- the luminaire insert has two or four reflector modules, which are fastened to the carrier element and exert a contact force on opposite sides of the illuminant module in the direction of the carrier element. In this way, the illuminant module is fastened on different sides on the carrier element.
- the luminaire insert has an axis of symmetry.
- the luminous means can be arranged along the axis of symmetry of the luminaire insert. In this way, a symmetrical light distribution can be achieved.
- the at least one light source comprises one or more LED (light emitting diode) and / or OLED (organic light emitting device).

- OLED organic light emitting device
- LED and OLED usually require only a low voltage, so that the luminaire insert according to the invention can comply with the creepage distances and clearances to be planned for safety reasons.
- another illuminant in particular a fluorescent tube, may be provided.
- the illuminant module is fixed to the carrier element only by the contact force of the reflector modules. This allows a particularly simple mounting of the lamp module on the support element.
- a guide may be provided on the illuminant module and / or on the carrier element in order to align the illuminant module relative to the carrier element. This facilitates the attachment of the lamp module.

- the reflector modules also exert a transverse force on the illuminant module transversely to the contact pressure.
- the lateral force acts laterally on the illuminant module.
- the transverse force may act along a plane along which the illuminant module extends. This embodiment is particularly preferred when several reflector modules abut on different sides of the lamp module. As a result, the lamp module can be clamped between the reflector modules, whereby it is aligned in the lateral direction.
- a reflector module applies force to an edge or edge of the light module. Further, in some embodiments, another reflector module applies force to an opposite edge or edge of the light emitting module. In other embodiments, an opposite edge or an opposite edge of the light module abuts against a structure of the carrier element. This also allows positioning of the lamp module in a predefined position.
- each of the reflector modules further comprises a light-diffusing and / or light-directing structure.
- the efficiency of the lamp can be further improved.
- the lighting properties of the lamp can be specifically influenced in order to achieve a desired lighting impression and a desired light distribution curve.

- the light-influencing structures can be arranged on an inner and / or an outer side of the primary cover.
- the primary cover can diffuse diffusely. This prevents a viewer from being blinded by the light source.
- the primary cover can be made of plastic, in particular of polymethyl methacrylate (PMMA).
- the primary cover completely covers the lamp module and the reflector modules.
- the modules are isolated from an environment of the luminaire insert, so that they are dust and moisture protected.
- the modules are protected from contamination or misalignment by direct contact by an installer or user.
- the primary cover also prevents the modules from being disassembled accidentally. This is particularly advantageous when the lamp module and / or the reflector modules are attached to the support element without tools.
- the primary cover is arched, in particular trough-shaped arched. This allows a light emission in different directions.
- the primary cover is releasably secured to the support member.
- the primary cover can be fastened to the support element without tools, preferably by means of a snap or latching connection. This facilitates the assembly and disassembly of the primary cover.
- the primary cover may abut one or more of the reflector modules. As a result, a displacement of the reflector modules can be prevented and the stability of the luminaire insert can be further increased.
- the primary cover clamps one or more of the reflector modules, in particular to the carrier element. This allows easy attachment of the reflector module.
- the carrier element is made of metal, in particular aluminum. This allows an efficient heat dissipation from the lamp module, so that the lamp is well cooled.
- the support member may further comprise cooling fins for improving the cooling.
- the metal gives the luminaire insert a high mechanical stability.
