Sealing frame for a lamp optical system

A kit for providing an optionally sealed luminaire (100), comprising:

• a luminaire housing (9),
• a plurality of luminaire optical systems (6) with optical edges (8) identical to one another but with different optical sides (7), in particular for different light-influencing light emission, in each case for connection to the luminaire housing (9) for defining a luminaire compartment (102) for accommodating illuminants (103) for emitting light from the luminaire (100) via the corresponding optical side (7), and
• a sealing frame (1) for sealing insertion between the luminaire optical system (6) and the luminaire housing (9) of a luminaire (100), comprising:
• a supporting frame (2) having a peripherally extending main frame (3) surrounding an inner region (I), wherein the supporting frame (2) or at least the main frame (3) thereof is produced from a light-transparent material;
• and
• a sealing element (5) which is connected to the main frame (3) in such a way that the sealing element (5) extends in a peripherally closed manner along the main frame (3) and protrudes away from same;
• wherein the sealing frame is configured to be inserted between the luminaire housing and the luminaire optical system such that the sealing element (5) is sealingly clamped between the luminaire housing and the luminaire optical system;
• wherein the sealing frame makes sealing contact with the sealing element (5) on the respective optical edges (8) of the respective luminaire optical system (6), in each case to form the luminaire (100) comprising the luminaire housing (9) with the optical system (10) sealingly connected to the luminaire housing (9) via the sealing element (5), the sealing element (5) being sealingly clamped between a sealing portion (90) of the luminaire housing (9) and the optical edge (8), so that the optical system (10) with the luminaire housing (9) delimits a closed luminaire compartment (102), which has the optical compartment (11) and is sealed off from the outside, for accommodating illuminants (103) for emitting light from the luminaire (100) via the optical side (7), and
• LED illuminants (103) are arranged in the luminaire compartment (102) for emitting light via the optical side (7), lying flat against the luminaire housing (9).
