  • the invention further, relates to a method for supplying a programming signal to a control circuit of a driver.
  • drivers for lighting means comprise a control circuit, e.g. for controlling the core functions of the driver.
  • driver control circuit In order to program or configure such a driver control circuit, it is known to use existing communication ports of the driver, e.g. for an initial wire bound programming during a production process, or for an additional wireless configuration / reprogramming. For example, this programming is carried out with one of the following technologies: DALI, NFC, or PLC.
  • US 2019/261471 A1 discloses a driver for lighting means, wherein an antenna port of the driver is connected to an input terminal of a radio circuit of the driver to facilitate a reduction of energy use by various sensors.
  • control circuit is also arranged to process wireless signals received by the antenna port).
  • the lighting means comprises LED luminaires.
  • the lighting means can also comprise other lighting technology devices, such as sensors, control device such as light switches, or emergency luminaires.
  • the integrated programmable control circuit of the driver can comprise a microcontroller or an ASIC.
  • the microcontroller or ASIC can be configured to process the control signal received at the antenna port.
  • operating parameters for the driver are encoded in the programming signal and the control circuit is adapted to decode such programming signal.
  • the operating parameters programmed may be e.g. one or more, even all, of:
  • the operating parameters of the driver can comprise an output current or voltage provided to the lighting means, a dimming range of the lighting means, commissioning information or licensing information.
  • control circuit is adapted to decode the programming signal which is a pulse width modulation (PWM) signal supplied in a direct electrical contact (as opposed to wirelessly) at the antenna port.
  • PWM pulse width modulation
  • the driver comprises a printed circuit board (PCB) and the antenna port is arranged on the PCB.
  • PCB printed circuit board
  • the housing is arranged to cover most of the PCB and comprises an opening for the antenna port or does not cover the antenna port.
  • the invention relates to a method for supplying a programming signal to an integrated control circuit comprised in a housing of a driver for lighting means, comprising: electrically contacting a wireless communication antenna port of the driver; supplying the programming signal to the antenna port; and forwarding said signal to an input terminal of the control circuit.
  • LED luminaire shall mean a luminaire with a light source comprising one or more LEDs or OLEDs. LEDs are well-known in the art, and therefore, will only briefly be discussed to provide a complete description of the invention.
  • the aspect of the present invention might contain integrated circuits that are readily manufacturable using conventional semiconductor technologies, such as complementary metal-oxide semiconductor technology, short "CMOS".
  • CMOS complementary metal-oxide semiconductor technology
  • the aspects of the present invention may be implemented with other manufacturing processes for making optical as well as electrical devices.
  • a driver 300 for lighting means comprising an antenna port 302a according to an embodiment is shown.
  • the driver 300 for lighting means comprises output terminals +LED, -LED for supplying lighting means, for example, an LED load. Moreover, the driver 300 for lighting means comprises a casing and a wireless communication antenna port 302a exposed to the outside.
  • the antenna port 302a is connected to an integrated programmable control circuit 301 of the driver 300 such that a programming signal supplied from the external to the antenna port 302a by an electrically conducting connection is received at an input terminal of the control circuit 301 and processed by the control circuit 301 of the driver 300.
  • the casing or housing of the driver 300 can be a metal casing.
  • This antenna port 302a can be used for fast programming of the control circuit 301 if no additional physical interface is available.
  • the port 302a can be contacted by a probe, e.g., a needle probe or similar of a driver programming device, during a production step of the driver.
  • a probe e.g., a needle probe or similar of a driver programming device
  • wire bound programming of parameters of the driver 300 such as nominal operation currents, licensing, etc., can be carried out after the housing of the driver.
  • the driver 300 for the lighting means can be designed such that the control circuit 301, e.g., a microcontroller, can receive at an input pin a programming signal, which has been input in a wire bound manner at the antenna port 302a of the driver 300.
  • the control circuit 301 e.g., a microcontroller
  • the programming signal can be a pulse width modulation (PWM) signal.
  • PWM pulse width modulation
  • the microcontroller of the control circuit 301 converts such a supplied PWM signal to a nominal value for the operation current supplied by the driver 300 to the lighting means.
  • a further advantage of this approach is that OEMs can use the existing tools for programming, no further software tools like DLLs or back ends are needed.
  • Fig. 2 shows a driver 300 comprising an antenna port 302a according to an embodiment.
  • the driver 300 shown in Fig. 3 can comprise a housing (not shown in Fig. 2 ), in particular a metal housing.
  • a communication antenna 302 can be connected to the antenna port 302a of the driver 300.
  • driver 300 It is, for instance not necessary to implement the exact current adjustment for a specific driver / lighting means combination in the driver software or firmware. This information can be programmed at a later stage via the antenna port 302a. Thus, less software efforts are required for the driver 300.
  • the antenna 302 is soldered onto the main printed circuit board, PCB.
  • the antenna port 302a can be connected to the optocoupler 401.
  • the optocoupler 401 can be connected to the microcontroller.
