Features

The LED luminaires of the CITY-LIGHT, LANTERN and MUSHROOM LUMINAIRE families interpret the form of the classic lanterns into a new and contemporary type. The result is an installation-friendly, modularly designed luminaire with an elegant, transparent impression and state-of-the-art, efficient lighting technology.
With the LED versions of these luminaire families the classic electrical insert has been replaced by the LED Module 540 especially developed by Siteco for this purpose. The modular construction ensures that forthcoming, more modern LED generations with higher performance levels can be upgraded later with ease.
The glare-free, directed light distribution is generated via a precisely matched combination of high performance LED arrays, 3-zone facetted reflectors and clear luminaire enclosures. The LED Module features an uniform, symmetric wide, asymmetric wide or extremely wide light distribution and is optionally available in colour temperatures 3000K (warm white) or 4000K (neutral white).
The LED Module is equipped with microprocessor-controlled LED operating electronics. This makes available a series of functions. These have been combined into three performance packages: Basic, Plus and Premium. All make use of the outstanding property of LED light sources in reducing luminous flux without loss. These values are either factory-set (Basic variant), can be individually set with the Siteco® Service Box (Plus variant) or centrally set via Street Light Control (Premium variant). The Plus and Premium versions offer the widest spectrum of efficient control of LED luminaires according to requirements.
All optical components and the electrical inserts for conventional lamp technology as well as the LED module of the luminaire families MUSHROOM, LANTERN, LANTERN CLASSIC, LANTERN DELUXE, CITY-LIGHT PLUS and CITY-LIGHT ELEGANCE can be interchanged thanks to outstanding availability of replacement parts and the rapid, maintenance-friendly exchange of components, allowing greater flexibility for design.

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 | integrated, programmable timer for reduction of luminous flux in two steps | settable luminous flux for max. operation and for both reduction levels | all parameters can be set with the Service Box | 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:
Street Light Control: for individual monitoring and control of the luminaire from a central control point from any distance via LON PowerLine without supplementary control wire (instead of SDI) | further functional range like Plus version.

Luminaire can be operated with factory pre-setting. The pre-setting with the Plus and Premium versions can be modified with the mounted and 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

Self-centering mast mounting element of diecast aluminium; glass-fibre reinforced polyester canopy element; housing and canopy with weather-resistant coating in Siteco® metallic grey (DB 702S); canopy underside white, functions as reflector; supporting element with ring of aluminium | cover of impact-resistant, UV-stabilised PMMA, transparent | protection rating: IP54 | insulation class: II

Electrical

Cover opened without tools | LED module and all electric components as removable unit
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 standardised 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

Luminaires with LED Module 540 with transparent cover: glare-free, uniform and directed light distribution via precisely matched combination of high-performance LED arrays, optionally with colour temperature 3000K (warm white) or 4000K (neutral white), 3-zone facetted reflectors and clear luminaire cover:

  • asymmetric wide light distribution (ST1.2a); for wide roads, without light spill to the rear
  • asymmetric extremely wide light distribution (P1.0a); for narrow roads and paths
  • symmetric wide light distribution (PL1.2s); for squares

Reflective corpus as decorative element and for visual guiding; white underside of canopy and corpus of LED module

Application areas
  • town centres
  • parks
  • residential streets and collection roads
  • residential areas
  • luminaire spacing 25…30m

Rapid advances in LED technology lead to permanent improvements in energy efficiency. This has the consequence that the luminous flux or power consumption may change accordingly. The current values can be found in the photometric report of each product and in the current download files of the lighting planning data.
