Abstract

An LED lighting device is disclosed. The LED lighting device includes a first LED circuit and at least one additional LED circuit. The first LED circuit and the at least one additional LED circuit each include LEDs connected in series. The LEDs in the first LED circuit emit a different color of light than the LEDs in the at least one additional LED circuit. The LED lighting device also includes a switch configured to be actuated by an end user and provide the end user with a means to produce a change in brightness of at least one of the first LED circuit or the at least one additional LED circuit, and switch at least one of the first LED circuit and the at least one additional LED circuit on or off.

First claim

The invention is claimed as follows:

1 . An LED lighting device comprising:
a first LED circuit and at least one additional LED circuit, wherein the first LED circuit and the at least one additional LED circuit each includes LEDs connected in series, and wherein the LEDs in the first LED circuit emit a different color of light than the LEDs in the at least one additional LED circuit; and a switch configured to be actuated between different positions by an end user and provide the end user with (i) a first position for selecting at least one of a different level of voltage or current to be input to at least one of the first LED circuit and the at least one additional LED circuit to produce a change in brightness of the at least one of the first LED circuit and the at least one additional LED circuit, and (ii) a second position for selectively switching at least one of the first LED circuit and the at least one additional LED circuit on or off when the end user actuates the switch, wherein the switch is integrated within the LED lighting device such that the switch is positioned to enable actuation by the end user, and wherein the LED lighting device is configured to be electrically connected to and powered with a mains power source.

2 . The LED lighting device of claim 1 , further comprising a lighting device package, wherein the lighting device package includes wire leads for electrical connection of the LED lighting device to the mains power source.

3 . The LED lighting device of claim 1 , further comprising at least one LED driver circuit configured to receive a high voltage input from the mains power source and provide a lower voltage DC output to at least one of the first LED circuit or the at least one additional LED circuit.

4 . The LED lighting device of claim 1 , wherein the first LED circuit and the at least one additional LED circuit are driven with two different DC voltage levels when the end user selects between the different positions of the switch.

5 . The LED lighting device of claim 1 , further comprising a driver configured to provide a voltage and a current to only one of the first LED circuit or the at least one additional LED circuit when the end user actuates the switch.

6 . The LED lighting device of claim 1 , further comprising a PCB substrate, wherein at least one LED from the first LED circuit and at least one LED from the at least one additional LED circuit are mounted on the PCB substrate and separated from each other by a distance of 3 millimeters (“mm”) or less.

7 . The LED lighting device of claim 1 , further comprising at least one LED driver circuit configured to receive a bridge rectified high voltage input from the mains power source and provide a DC voltage output to at least one of the first LED circuit and the at least one additional LED circuit.

8 . The LED lighting device of claim 1 , wherein the switch is mounted on a printed circuit board with the first LED circuit and the at least one additional LED circuit.

9 . An LED lighting device comprising:
a first LED circuit and at least one additional LED circuit, wherein the first LED circuit and the at least one additional LED circuit each includes LEDs, and wherein the LEDs in the first LED circuit emit a different color of light than the LEDs in the at least one additional LED circuit; and a switch configured to be actuated between different positions by an end user and provide the end user with a first position for selecting at least one of a different level of voltage or current to be input to at least one of the first LED circuit and the at least one additional LED circuit to produce a change in brightness of the at least one of the first LED circuit and the at least one additional LED circuit, wherein the switch is integrated within the LED lighting device such that the switch is positioned to enable actuation by the end user, and wherein the LED lighting device is configured to be electrically connected to and powered by a mains power source.

10 . The LED lighting device of claim 9 , further comprising a lighting device package that includes wire leads for electrical connection of the LED lighting device to the mains power source.

11 . The LED lighting device of claim 9 , further comprising at least one LED driver circuit configured to receive a high voltage input from the mains power source and provide a lower voltage DC output to at least one of the first LED circuit or the at least one additional LED circuit.

12 . The LED lighting device of claim 9 , further comprising a driver configured to provide a voltage and a current to only one of the first LED circuit or the at least one additional LED circuit when the end user actuates the switch.

13 . The LED lighting device of claim 9 , further comprising at least one LED driver circuit configured to receive a bridge rectified high voltage input from the mains power source and provide a DC voltage output to at least one of the first LED circuit and the at least one additional LED circuit.

14 . The LED lighting device of claim 9 , wherein the first LED circuit and the at least one additional LED circuit are driven with two different DC voltage levels when the end user selects between the different positions of the switch.

15 . The LED lighting device of claim 9 , further comprising a PCB substrate, wherein at least one LED from the first LED circuit and at least one LED from the at least one additional LED circuit are mounted on the PCB substrate and separated from each other by a distance of 3 millimeters (“mm”) or less.

16 . The LED lighting device of claim 9 , wherein the switch is mounted on a printed circuit board with the first LED circuit and the at least one additional LED circuit.
