Square LED surface-mounted luminaire with microprismatic cover panel PW19. For mounting on ceilings, walls and overhangs indoors. The optical system consists of a highly efficient PMMA cover with microprismatics. The microstructured PMMA prism surface of the optical system has an anti-glare effect, is non-yellowing and does not cloud. With symmetrically limited wide beam light distribution. Glare rating according to UGR classification (EN 12464-1) 80. Color location tolerance (initial MacAdam) = 3 SDCM. Average rated service life L80(tq 25 °C) = 100,000 h, average rated service life L90(tq 25 °C) = 50,000 h. The light source is replaceable in accordance with the ecodesign requirements (Regulation (EU) 2019/2020). The surface-mounted luminaire consists of a mounting body with connection unit, quick-connector and the operating device as well as an attached luminaire unit with LED system, cover plate, quick-connector and frame. Surface coated in white (RAL 9016). Dimensions (L x W): 607 mm x 607 mm, height 42 mm. The frame is 3-dimensionally profiled. The undercut creates a shadow gap and reduces the perceived overall height. Protection class (EN 61140): I, protection type (DIN EN 60529): IP40, shock resistance level according to IEC 62262: IK03, test temperature glow wire test according to IEC 60695-2-11: 650 °C. Weight: 7.4 kg. The packaging concept of the luminaire enables the operating device to be removed separately for pre-assembly, the other components of the luminaire remain protected until final assembly. With electronic operating device, digitally dimmable (DALI). Control gear in accordance with the DALI-2 standard (EN 62386). Luminaire can be switched and dimmed using a touch function via DALI control terminals (Touch DIM). The control gear is replaceable in accordance with the ecodesign requirements (VO (EU) 2019/2020). Control gear is idle-proof and protected against incorrect connection, short circuit, overload and overtemperature. ENEC certification by an independent testing center is in preparation. The luminaire can be equipped with the Monitoring ready (MOR) functionality on request. The product meets the basic requirements of the applicable EU directives and the Product Safety Act and bears the CE mark. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires that are coordinated in appearance. The variety of applications of the product range is further underlined by variants in the area of luminous flux packages, light distribution curves and protection classes. The basic range can be expanded to include project-specific luminaire features on request. Luminaire 10 years, spare parts (LED module, control gear, optical system) available 15 years after invoice date subject to reasonable changes in the interests of progress.
