iZHAGA

The PIR sensor used is a pyroelectric infrared sensor that detects fluctuations in infrared radiation (model no.: EKMC 1611111 from Panasonic).

Detection Area

The detection range is polarised. If a target enters the + and – detection areas at the same time, the signals will each be cancelled and detection could become impossible at maximum detection range.

Digital control of lighting

• Control light (switch on/off and dim)
  • by means of a runtime calendar
  • by means of a programmable calendar (in the light management system)
  • by means of light sensor incl. adjustability of a hysteresis threshold for unpredictable weather phenomena
  • by means of GPS location (seasonal)
  • Dimming with freely selectable dimming levels (in the management system) or by means of a predefined dimming level (in stand-alone operation)
• Separate switching of the light at dangerous or architectural points, e.g. pedestrian crossing, monuments,...
• Replacement for audio frequency/long wave ripple control technology (e.g. in combination with Switch Cabinet Controller)

Additional function of the iZHAGA-S

• Motion-controlled light via PIR sensor
  The movement is detected and switches the luminaire on.

Further lighting control functions

For example, running lights with directional lighting for tunnels or light control depending on traffic volume (e.g. traffic jam warning) in preparation.
Note: No additional components required

Measurement data collection

Measurement data acquisition is carried out via the connected DALI2 luminaire driver (see DALI2/D4i specification). The iZHAGA controller only records the runtime.

Maintenance factor function
A constant luminous flux can be achieved with the lighting controls slowly increasing power to counteract the lumen depreciation over the service life of the lamp. This avoids the need to over specify the luminous output to allow for lumen depreciation and thereby optimizes energy consumption.

Communication infrastructure for smart city applications

Using an open protocol, the existing street lighting infrastructure becomes an intelligent communication platform for further smart city applications.

The technology used is fully interoperable at the protocol and communication level due to the standardised protocol according to EN 14908-1. The transmission channel based on radio is standardised according to EN 14908-11 and is in preparation.

iZHAGA luminaire controllers create a reliable communication structure to which further smart city applications can be added.

iZHAGA allows the lighting to be controlled while maintaining power at the pole which is a prerequisite for adding additional applications.

Possible fields of application with additional sensors can be:

• Environmental technology (real-time measurement)
  • Fine dust
  • Nitrogen oxides
  • CO2
  • Ozone
• Weather data (real-time measurement)
  • Temperature
  • Humidity
  • Air pressure
  • Precipitation
  • Wind
  • Road ice detection
• Noise measurement
• Parking management
  • Detection and display of free/occupied parking spaces
  • Display on information boards
• Waste management (only possible in management mode)
  • Reporting of fill level to central location via e-mail or SMS
• Traffic management
  • Traffic counting (type and quantity)
  • Provision of data for traffic control
  • Pre-processed image data transmission for traffic measurement, blind spot assistant via signal light display
• Charging electric vehicles
  • Single-phase or multi-phase charging of electric vehicles with alternating current incl. energy consumption measurement
  • Different access options to the charging point (ad-hoc charging, app, RFID card)
  • Free/occupied message via street light and transmission to information systems
• Actuator data (e.g. information boards)
