The LED module 4 has a flat and thin extension (see e. g. figures 9-12, with aheight H in the range of 5-20 mm in a direction corresponding to the main direction oflight to be emitted from the at least one LED. The number of LED:s varies in dependenceof the intended use of the LED assembly, an may be as many as 40-50.
The LED assembly 2 further comprises a connector unit 8 provided with connector pins 10(see figure 3), and a functional module receiving recess 12 (see figure 3) shaped andstructured to receive and releasably attach a functional module 14 by mechanicalcooperation with attachment members 16 (see figure 3) of the fiinctional module 14. Therecess 12 is shaped and structured such that the connector pins 10 are positioned to be connected to connecting members 18 (see figure 3) of the fianctional module 14.
The LED assembly 2 also comprises a set of at least two functional modules 14. Eachfunctional module within the set has a unique function available when the fiinctionalmodule 14 is connected to the LED module 4. All functional modules 14 of the set haveidentically shaped module housings 20 provided with attachment members 16, andconnecting members 18 being configured to receive supply energy to the fianctionalmodule 14, from the LED module 4, and to establish bi-directional communicationbetween the LED module 4 and the fianctional module 14 when attached to the LED module.
According to an embodiment, the fianctional module receiving recess 12 is shaped andstructured to provide electrical insulation of an attached functional module 14 from thehigh voltage circuitry 6, except the electrical connection via the connector pins. The recess is made from an electrically insulating material, e.g. any plastic material.
Preferably, the module housing 20 has a flat configuration having a predeterrninedmaximum height, a width and a length, and the receiving recess 12 is shaped andstructured such that the plane of the fianctional module 14, when attached to the connectorunit 8, is essentially parallel to the flat extension of the LED module 4. This is illustratedin the perspective view of figure 13, but also in the side views shown in figures 9-12. Inaddition, the connector unit 8 is arranged beside the LED:s. Thereby is achieved that thefunctional module, when attached to the LED module, does not shadow the LED. In oneexemplary embodiment, the predeterrnined maximum height is 5 mm, the maximum width is 10 mm, and the maximum length is 25 mm.

A FELV controlsignal is insulated for low voltage supply (e. g. to DALI and 0 to 10 V). In addition, it is possible to provide current for sensors, etc.
In figure 3 is also illustrated attachment members 16. These may be protrusions to beapplied to hold the connector unit within the recess by snap-fitting to mating grooves at inner walls of the recess.
In figures 1 and 2 a block diagram of the LED module is shown. The LED module 4comprises a control unit 22 configured to determine the mode of operation for the LEDassembly 2 to be in a normal mode when no functional module 14 is attached (see figure1) or in a functional module mode (see figure 2) when a functional module 14 is attachedto the LED module 4. Preferably, the control unit 22 is configured to determine the modeof operation by detecting an electrical load connected to the connector pins 10. When inthe fianctional module mode, the LED assembly 2 works according to functions defined bythe attached functional module 14. It is deterrnined in the respective hardware of the LEDmodule and the attached functional module from where the energy comes from. Thereason is the different standards applied in different functional modules, i.e. the energysource to be applied is deterrnined in dependence of the function of the attached functional module.
The set of functional modules 14 comprises at least two functional modules configured toimplement at least two different functions of the following: Digital Addressable LightingInterface (DALI), DALI Device Type 8 (DT8), Zigbee (wireless), Bluetooth, motionsensor, light sensor, 0-10V, and Built-in Dimmer (Push, Potentiometer or Pulse). These functions will be discussed more in detail below.
Each of the fianctional modules comprises a processing unit, a power Conversion unit, anda functional unit, and that the fianctional unit comprises circuitry to implement the unique function of each of the fianctional modules. 1. DALI Digital addressable lightning interface, or DALI, is a global standard that allows ballasts,controllers, switches and sensors to communicate with other DALI-compatible devices.DALI began in the late 1990s, but has since undergone drastic changes that expand itsscope and improve its efficiency. The main focus of DALI has been to facilitate theinstallation and use of ballasts and relay switches that enable dimmable, adaptablelighting. 2. DALI DT8 (Device Type 8) This is a standard solution based upon DALI, adapted for Human Centric Lighting. A two-channel LED solution that meets the standard for CCT change. 3. Zigbee ZigBee is a low-cost, low-power, wireless mesh network standard targeted at battery-powered devices in wireless control and monitoring applications. ZigBee delivers low-latency communication. ZigBee chips are typically integrated with radios and withmicrocontrollers. ZigBee operates in the industrial, scientific and medical (ISM) radiobands. 4. Bluetooth A communication protocol based on Bluetooth, e. g. Casamabi, Wirepas, Bluetooth Mesh.5. Motion sensor Often designed with high frequency sensors. The sensor should respond to movementswithin a predefined area. The light sensor is configured to detect people in the predefinedarea. It does require movement within close proximity of the sensor. 6. Light sensor To tum the unit on or off depending on whether there is light around it or not. Thefunctional unit includes the option to change the settings for activation, e.g. not tum onduring the day when it is bright. 7. 0- 1 0V Standard lighting protocols in certain areas. 8. Built-in dimmerBy using a pulse or a rotary switch in different settings, there may be an opportunity for construction equipment.
As mentioned above, each fianctional module comprises a processing unit configured toimplement control of the function of the functional module. The control unit is conf1guredto bi-directionally communicate With the LED module via the connector unit. Thecommunication is performed at a voltage level below 20 V. This provides a prerequisitefor the LED assembly, i.e. the LED module and an attached functional module, to connectto the outside World.
The control unit may then be enabled to control circuitry Within the functional module,e.g. to establish a Wireless communication link to an extemal communication source. Thecontrol unit may then receive operating instructions from the extemal source and in tumapply control signals to the LED module to control the LED module according to the received operating instructions.
The fianctional module is installed by the customer according to his/her needs. These LEDmodules have not functional module mounted but are fully expandable according to thefunction of an attached functional module, e.g. for DALI or other fi1nctions. Without thefunctional module mounted, it Works just as usual.
By integrating a connector unit into the LED module, it Will be possible to easily introduce new functions into our LED modules.
The present invention is not limited to the above-described preferred embodiments.Various altematives, modifications and equivalents may be used. Therefore, the aboveembodiments should not be taken as limiting the scope of the invention, Which is defined by the appending claims.
