Abstract

In some embodiments, a solid state lighting circuit may include one or more of the following features: (a) a plurality of emitters operably connected to a power supply (b) the power supply operably coupled in series with a current limiting device, where one or more of the emitters is bypassed with a switched circuit, and (c) at least one MOSFET switch operably coupled to the voltage divider circuit.

Claims

1. A solid state lighting circuit, comprising:

a plurality of emitters operably connected to a power supply; and

the power supply operably coupled in series with a current limiting device, where one or more of the emitters is bypassed with a switched circuit.

2. The circuit of claim 1, wherein a controlling signal for the switched circuit is derived from the power supply.

3. The circuit of claim 1, wherein a controlling signal could be from any source.

4. The circuit of claim 1, wherein the power supply is an AC power source.

5. The circuit of claim 1, further comprising at least one MOSFET switch operably coupled to the voltage divider circuit.

6. The circuit of claim 1, wherein the voltage divider circuit allows the circuit board to regulate voltage and thus dim the at least one emitter.

7. The circuit of claim 6, wherein a plurality of emitters can be dimmed.

8. A solid state lighting circuit, comprising:

a plurality of emitters operably connected to a power supply; and

the power supply operably coupled in series with a current limiting device, where one or more ballast can be bypassed with a switched circuit.

9. The circuit of claim 8, wherein the plurality of emitters can be bypassed with the switching circuit.
