Problems solved by technology

However, this frequency band is not wide enough to accommodate enough light sources for the considered system
Also, these IR based remote control devices may interfere with the envisioned coded lighting system
So for the IR band there is also potential interference from other light sources
Also, it should be noted that sources of interference can be very dependent on location and time

Embodiment Construction

[0032] The following embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numerals denote like elements throughout.

[0033] figure 1 Shown is a lighting system 100 comprising at least one light source, which is schematically indicated by reference numeral 102 . Light source 102 may be part of a lighting control system. It should be noted that the term "light source" denotes a device that provides light in a room for the purpose of illuminating objects in the room. Examples of such light providing devices include lighting devices and luminaires. In this context, a room is typically an apartment room or office room, a gymnasium hall, a room in a public place, or a part of an outdoor environment, such as a part of a street. As indicated schematically by arrow 108, each light source 102 is capable of emitting light. The emitted light inclu...

Abstract

Coded light has been proposed to enable advanced control of light sources and transmit information using light sources. Methods, devices and systems configured to operate a coded lighting control system, which is robust to interference from other sources of light are proposed. The method is based on sensing the light by a remote control device, and based on the sensing result adapting the identifiers used by the different light sources. By assigning a code identifier to the light source based on light received by the light receiver the code identifiers may be selected such that the influence of light interfering with the light source identifiers may be mitigated.

Description

technical field [0001] The present invention relates to operating lighting control systems. In particular, the invention relates to methods and apparatus for operating a lighting control system comprising a plurality of light sources, each light source being allowed to emit coded light. Background technique [0002] The use of visible light (VL) and infrared (IR) communication for selection and advanced control of light sources has been previously proposed and referred to as coded light (CL). For transmission of CL, light-emitting diodes (LEDs) are usually considered, which allow reasonably high modulation bandwidths. This in turn can lead to a fast response of the control system. The feasibility of embedding identifiers into light from other light source types (incandescent, halogen, fluorescent and high-intensity discharge (HID) lamps) has also been demonstrated. [0003] These light source identifiers or codes allow for applications such as commissioning, light source ...
