OSRAM LS
SMALL BELL LED
with transparent cover with cover, stippled
Features

A classic, decorative design, simultaneously better light, and with outstanding optics and significantly lower costs. The BELL in the LED variant is the future-fit solution for decorative lighting tasks in outdoor areas.
Two construction sizes, two light colours, several control variants and various covers make it the flexible all-rounder for all applications.
The BELL LED and the special BELL LED module are ideally suited for the modernising or expanding of existing installations with their low effort and simple handling. And without compromises, because concealed in the BELL LED is the slightly modified module of the efficient Streetlight 10 luminaire from Siteco.
Due to Siteco gear tray technology, upgrading to higher performance, future LED modules is easily implemented.

Special features
  • for standardised lighting according to DIN EN 13201, for wide luminaire spacing with uniform illumination of the road
  • LED operating electronics with wide range of functions for efficient control of luminous flux
  • light colours: warm white (3000K) or neutral white (4000K)
  • highly simple mounting and maintenance: modular gear tray concept, can be simply replaced for upgrading versions with conventional lamps to LED or upgrading LED versions to future, more efficient LED generations
  • ideal for the expansion of existing installations - visual appearance of the road is maintained
  • family character via two construction sizes
  • bayonet catch allows rapid, tool-free mounting of BELL to curved mast extension
  • multiple arrangements possible
Functions

According to version, the luminaires are equipped with differing functionality ranges for light management and monitoring:
All versions with temperature monitoring for protection of LEDs from thermal overload
Basic performance package:
Luminous flux reduction via 230V control voltage | no luminous flux constancy
Plus performance package with electronic type plate:
Luminous flux constancy over complete service life | Dimming without an external control signal: integrated, factory pre-set and programmable timer for luminous flux reduction in two steps (time value and dimming value for max. operation and both reduction levels is set via the Service Box on the unmounted luminaire) | on request: can be integrated via SDI into existing digital control systems and controlled from a central control point | alternative luminous flux reduction via 230V control voltage
Premium performance package with electronic type plate:
PowerLine-ready with integrated SLC luminaire controller for integration into intelligent, networked light management and monitoring systems (data transmission via standardised LON protocol without supplementary control wires) | further functional range like Plus version (factory pre-setting can be modified with the mounted or dismantled luminaire)

Electronic type plate: special component of Plus and Premium performance packages, saving type information, system-specific configuration and operating/performance data. Automatically configures newly installed LED units or ECGs

Housing

Glass-fibre reinforced polyester housing with integral bayonet connection to curved mast extension; luminaire-specific Siteco curved mast extension, steel, galvanised; housing and curved mast extension with weather-resistant coating in Siteco® metallic grey (DB 702S) | all-round, air-permeable wool-felt gasket in housing profile | PMMA luminaire cover in two versions, with bayonet catch | protection rating: IP54 | insulation class: II

Electrical

Luminaire opened without tools | LED module and all electric components on removable gear tray
Basic performance package: LED module with 3-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction) | control signal: USt= 230V --> 100% luminous flux; USt= 0V --> approx. 50% luminous flux
Plus performance package: LED module with 5-pole connection terminal, max. 2.5mm² (2-pole for mains supply + 1-pole for 230V control voltage for power reduction + 2-pole for Siteco® Digital Interface (SDI))
Premium performance package: LED module with 2-pole connection terminal, max. 2.5mm² (control and monitoring of the luminaire from a central control point without supplementary control wires; data transmission according to standardized LON protocol)
Connection for potential equalisation as optional accessory. Required to avoid electrostatic charges when installing to non-conductive masts (wood, concrete, plastic etc.)

Lighting technology

Optic system consists of precisely matched combination of high-performance LED arrays, extremely precise 3-zone faceted reflectors and clear or stippled luminaire cover:
The high luminance of the LEDs is dispersed and converted by the system to softly distributed light for highly uniform, standard-compliant illumination with flowing contrast transitions and significantly reduced glare.
Additional reduction of light spill to the rear due to optional shielding on building side

Application areas
  • squares
  • parks
  • residential streets and collection roads
  • residential areas
  • for large light-point spacing of 30…40m
