Abstract

A programmable light apparatus includes a LED module and a driver. The driver has a current adjustable circuit that supports multiple types of LED modules. By sending a programming signal to a wireless circuit of the driver, the current adjustable circuit determines a correct setting to provide a necessary driving current to a corresponding LED module.

First claim

The invention claimed is:

1. A programmable light apparatus, comprising: a LED module, the LED module being configured to one of multiple predetermined settings, wherein the LED module comprises multiple LED filaments: and a driver designed for supporting all of the multiple predetermined settings, comprising: a current adjustable circuit tor converting an external power to a driving current to the LED module; a wireless circuit for receiving a programming signal to indicate a number of the multiple LED filaments from an external device; a processor circuit for converting the programming signal to a code; an execution circuit for writing the code to a storage, wherein the current adjustable circuit generates the driving current according to the code stored in the storage; and a switch for users to set a switch setting, wherein the processor circuit references the switch setting in addition to the programming signal to determine the code, the programming signal is corresponding the number of the multiple LED filaments for changing a parameter of the driver to correctly drive the multiple LED filaments.

2. The programmable light apparatus of claim 1 , wherein the external device is a mobile phone sending an NFC signal as the programming command.

3. The programmable light apparatus of claim 1 , wherein the wireless circuit, the processor circuit and the execution circuit are operated with a signal electricity of the programming signal, even when the current adjustable circuit does not receive the external power source.

4. The programmable light apparatus of claim 1 , further comprising a battery for supplying power to the wireless circuit, the processor circuit and the execution circuit so that when the current adjustable circuit does not receive the external power source, the wireless circuit, the processor circuit and the execution circuit are still operable.

5. The programmable light apparatus of claim 1 , wherein the wireless signal is an NFC (Near Field Communication) signal.

6. The programmable light apparatus of claim 1 , wherein the processor circuit comprises an amplifier for amplifying the programming signal.

7. The programmable light apparatus of claim 1 , wherein the code stored in the storage is sent to the current adjustable circuit to control an output current of the current adjustable circuit.

8. The programmable light apparatus of claim 1 , further comprising a PWM (Pulse Width Modulation) circuit retrieving the code in the storage to generate a corresponding PWM signal to adjust the current adjustable circuit.

9. The programmable light apparatus of claim 1 , wherein the processor circuit decodes the programming signal for determining whether the programming signal is an authentic signal.

10. The programmable light apparatus of claim 9 , wherein the programming signal is encrypted with a secret key to prevent unauthenticated operation to adjust the current adjustable circuit.

11. The programmable light apparatus of claim 1 , wherein the programming signal indicates a desired color temperature parameter.

12. The programmable light apparatus of claim 1 , wherein the programming signal indicates a desired color parameter.

13. The programmable light apparatus of claim 1 , wherein the programming signal comprises an updated firmware code for the driver.

14. The programmable light apparatus of claim 1 , further comprising a housing containing the LED module and the driver forming a downlight device.
