Abstract

Provided is a light emitting diode (LED) lighting fixture including a light engine, a plurality of LEDs, an LED driver, and a near field communication (NFC) electrically erasable programmable read only memory (EEPROM) circuit. The NFC EEPROM circuit provides an avenue for storing information pertaining to the LED light fixture that is easily accessible.

First claim

What is claimed is:

1. A method for storing data related to operation of a lighting system including a light engine including a plurality of LEDs controlled via a driver, and a memory circuit coupled to the light engine, wherein the memory circuit comprises an electrically erasable programmable read-only memory (EEPROM) electrically coupled to an antenna for powering the EEPROM by an electromagnetic field, the method comprising:
producing the data;
programming the data into an external near-field communication (NFC) enabled device;
transmitting the data to the memory circuit via the NFC enabled device;
querying the memory circuit for the data; and
programming an LED driver with the data, wherein the LED driver is located external to the light engine.

2. The method for storing according to claim 1 , further comprising storing the data set on the EEPROM.

3. The method for storing according to claim 2 , wherein the data set stored on the EEPROM being configured to provide parameters for programming the light engine.

4. The LED data storage method of claim 1 , wherein the light engine acquires and stores the data wirelessly via the NFC enabled device.

5. The method for storing according to claim 1 , wherein the data is regarding the level of output current required from the LED driver for the light engine.

6. A method for storing data related to operation of a lighting system comprising a memory circuit and a light engine including a plurality of LEDs controlled via a driver, wherein the memory circuit comprises an electrically erasable programmable read-only memory (EEPROM) electrically coupled to an antenna for powering the EEPROM by an electromagnetic field, the method comprising:
producing the data;
programming the data into an external near-field communication (NFC) enabled device;
transmitting the data to the memory circuit via the NFC enabled device;
querying the memory circuit for the data; and
programming an LED driver with the data, wherein the LED driver is located external to the light engine.

7. The method for storing according to claim 6 , wherein the data is regarding the level of output current required from the LED driver for the light engine.

8. A method related to operation of a lighting system, the lighting system comprising a memory circuit and a light engine including a plurality of LEDs controlled via a driver, the method comprising:
querying the memory circuit for data, wherein the memory circuit comprises an electrically erasable programmable read-only memory (EEPROM) electrically coupled to an antenna for powering the EEPROM by an electromagnetic field; and
programming an LED driver with the data, wherein the LED driver is located external to the light engine.

9. The method according to claim 8 , wherein the data is regarding the level of output current required from the LED driver for the light engine.

10. The method according to claim 8 , further comprising a step of erasing the data after the step of programming the LED driver.

11. The method according to claim 8 , wherein the data stored on the EEPROM is encrypted.
