Luminaire type
Square recessed LED luminaire with microprismatic cover PW-X. Unique light effect due to an inner luminous gap and wide-area light emission. Inner light gap can be individually designed according to customer requirements. The luminaire is part of a range of recessed, surface-mounted and suspended luminaires with a harmonised appearance. The application variety of the product series is underlined by variants regarding luminous flux packages, light distribution curves and protection ratings. On request, luminaire features can be adapted in a project-specific way.
Applications
For workstations with computer screens. Offices, Corridors, Foyers, Conference rooms, Retail areas, waiting zones. Generation of an enhanced depth effect in the room.
Mounting methods
LED lay-in luminaire for system ceilings with exposed grids. .. System dimension 600 x 600 (M73). The luminaire is also suitable for applications in plasterboard ceilings with an accessory ordered separately.. Installation in cut apertures via mounting accessory requires a ceiling material thickness of 25 mm - 40 mm.
Optical system
The optical system consists of a highly efficient PMMA cover with microprisms. PW (prismatic wide). The microstructured PMMA prism surface of the optical system has a glare-reducing effect, is non-yellowing and dœs not cloud. With narrow-wide light distribution. Glare evaluation (EN 12464-1) according to UGR < 19. Suitable for VDU workstations according to EN 12464-1 via limited luminance L ≤ 3000 cd/m² for beam angle above 65° all-round. Harmonious light effect due to homogeneously illuminated light emission. Individual design of the light emission surface (e.g. with printing) and other special solutions are possible on request.
LED system
Luminaire luminous flux 4200 lm, connected load 31,00 W, luminous efficiency of luminaire 135 lm/W. Light colour neutral white, correlated colour temperature (CCT) 4000 K, Colour locus tolerance (initial MacAdam) ≤ 3 SDCM corresponds to very high colour uniformity of the LEDs in application, general colour rendering index (CRI) Ra > 80. Mean rated service life L80(tq 25 °C) = 100,000 h, mean rated service life L90(tq 25 °C) = 50,000 h.
Luminaire body
Luminaire body of extruded aluminium profile. Surface coated white, (RAL 9016). The narrow side profile is flush with the trunking. The luminaire frame is profiled in a 3-dimensional way to generate a depth effect on the ceiling. Luminaire can be covered with insulatin material at ta25°C, ta35 °C without insulation materila can be also be used.
Electrical connection
Polarity-protected rapid connection with mains through-wiring up to Ø 2.5 mm². Connection of the ballast unit to the luminaire (Plug ‘N Play). The luminaire’s packaging concept facilitates separate removal of the control gear unit for pre-assembly, leaving the remaining luminaire components protected until final assembly.
Electrical version
With external operating device, switchable. Control gear unit is open-circuit proof and protected against faulty connection, short circuit, overload and overtemperature. The control gear is replaceable. Output ripple of the control gear unit ≤ 4 % for effective control of the LED system and for flicker-free light.
