Problems solved by technology

[0003] However, lighting devices equipped with wireless connections may deal with conflicts when attempting to provide multiple functions simultaneously via the same wireless connection
For example, the functionality of indoor positioning may require successive beacons of identifiers for precise positioning, which conflicts with using the same beacons to provide operational status information, for example

Embodiment Construction

[0042] Figure 1A -C schematically depicts an embodiment of a lighting device 100 according to the invention by way of non-limiting example. The lighting device 100 includes a controller 1 , a transmitter 2 , a driver 3 and a light source 4 . All components are operatively coupled to provide wireless connectivity to lighting device 100 . The driver 3 drives the light source 4 . The controller 1 controls the driver 3 and the transmitter 2 .

[0043] The lighting device 100 further comprises a temperature sensor 5 for detecting the internal temperature of the driver 3, which is a good indicator of the health and / or remaining life of the lighting device. A temperature sensor 5 is installed in the driver 3 . The controller 1 is configured to receive measurements from the temperature sensor 5 and to store a series of such measurements as measurement data. The measurement data can then be transmitted via the transmitter 2 .

[0044] Similarly, in alternative embodiments, the te...

Abstract

The invention provides a lighting device comprising a transmitter, a controller and a sensor; wherein the controller is configured to control the transmitter to repeatedly transmit a second wireless message interleaved with a first wireless message, wherein the first wireless message has a first duration and comprises a first signal, wherein the second wireless message has a second duration and comprises a second signal; wherein the first duration and / or the second duration is adaptive during a lifetime of the lighting device; wherein the controller is configured to receive a measurement from the sensor and control the transmitter to transmit the second wireless message comprising the second signal comprising the measurement.

Description

technical field [0001] The invention relates to a lighting device and a corresponding method for transmitting signals by the lighting device. The invention further relates to a location-based service system; and to a computer program product. Background technique [0002] More and more luminaires are equipped with wireless connectivity to provide functionality beyond just lighting, such as, for example, enabling lighting control or providing location-based services, facilitating communication, allowing on-boarding initialization, providing location-based services and / or Indoor positioning, etc. For example, VLC (via Signify) is being implemented to provide indoor positioning capabilities for luminaires. For this purpose, the luminaire can transmit a 16-bit code called a VLC identifier, ie allowing location via triangulation, for example using the VLC identifier. Similarly, a Bluetooth-ZigBee combo chip (via Signify), for example, is used to enable lighting control functio...
