Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a luminaire and lighting trunking systems, preferably for indoor applications. The invention further relates to a method for operating the luminaire and lighting system to scan, collect, process in the edge and in the cloud various data structures derived from RFID tags.

BACKGROUND OF THE INVENTION

Radio frequency identification (RFID) systems are currently the most widely used technology for tracking assets. The system is expensive on infrastructure but very cheap on tags.
RFID is used in different applications in order to provide unique identification codes related with a set of particular items. These items may comprise products in a store or pallets in a warehouse, persons in a race, pets, racehorses, farm animals, cars passing a tollbooth or entering a parking lot, etc.
Usually, singular RFID "tags" are attached to each item where each tag comprises a "chip" encoding digital identification data and an antenna that can communicate wirelessly to an RFID "reader." In some cases "passive" tags are used, where the power necessary to receive a query and transmit identification data back to the reader is also provided via the wireless connection.
In some cases use is made of "active" tags which incorporate batteries to provide a higher power signal that can be read from greater distances.
RFID systems have been implemented over a wide range of radio frequencies. Common embodiments exist using frequencies near 100 kHz, 10 MHz, and various UHF frequencies (100s of MHz to a few GHz). The choice of the range of frequencies is dictated on the one hand by available radio bands not designated for other applications and on the other hand by the performance needs of particular applications.
Most of production, logistics and retails systems make use of such tags.
However, traditional RFID solutions are expensive for the infrastructure and implementation and do not match the expectations.
Thus, there is a need for an improved luminaire and lighting trunking system.

SUMMARY OF THE INVENTION

The object of the present invention is achieved by the solution provided in the enclosed independent claims. Advantageous implementations of the present invention are further defined in the dependent claims.
According to a first aspect, the invention relates to a luminaire and lighting trunking system, comprising a housing, at least one lighting module or lighting trunking system, a control unit controlling the operation of the lighting module, a RFID antenna integrated in the luminaire or lighting trunking system, as well as a RFID controller, designed to process signals detected by the RFID antenna and sending the processed signals to a edge processing or cloud based remote unit, via a wireless or wire-bound communication link.
The lighting trunking systems are well known in the prior art and they are provided by different providers. For example, LED linear trunking systems are continuous-row lighting assemblies that utilize trunking rails in order to integrate individual lighting fixtures which may include LED light modules, power supplies, lighting controls, and emergency battery packs. The flexible trunking systems can be configured in different ways in order to meet challenging demands for interior lighting in commercial and industrial buildings.
This provides the advantage that a very efficient real time asset tracking system can be created. Luminaires and associated trunking systems, are often installed at locations which are also suitable for RFID identification and tracking. The detection angle of the antenna may correspond to the area covered by the light emitted by the luminaire - thus the light cone can give a user a visualization of the RFID coverage area.

In an implementation form of the luminaire lighting trunking system according to the first aspect, the RFID controller is designed to process signals detected by the RFID antenna in order to extract an RF ID sent from a RFID tag.
This provides the advantage that objects having the RFID tag can easily be identified and, therefore, processes requiring the identification of objects can be made faster.
In an implementation form of the luminaire lighting trunking system according to the first aspect, the RFID controller sends the RF ID to said remote unit.
In an implementation form of the luminaire according to the first aspect, the communication link is a DALI bus or a RF wireless link such as Bluetooth, Tread (6lowpan) or WLAN link.
This provides the advantage that well known communication links are used and, therefore, are easier to implement.
In an implementation form of the luminaire according to the first aspect, the RFID antenna is integrated in the housing of the luminaire or attached to the associated lighting trunking system.
In an implementation form of the luminaire or lighting trunking system according to the first aspect, the RFID antenna covers frequencies from 30 KHz to 300 KHz.
