Abstract
An auxiliary power system for powering an auxiliary circuit is connected to the same power source that powers the lighting element within a luminaire. The auxiliary power system may be connected to the output of the power source in series or in parallel with the lighting element. The power source may be an LED driver and the lighting element may include one or more LEDs or the power source may be an electronic ballast and the lighting element may be one or more fluorescent lamps.
Claims23
A luminaire, comprising:
- an LED driver, having a first output and a second output;
- an LED lighting element including at least one LED connected between the first output and the second output of the LED driver;
- an auxiliary power system, wherein the auxiliary power system is connected between the first output and the second output of the LED driver and in parallel with the LED lighting element,
- wherein the auxiliary power system includes a voltage converter configured to convert an output voltage received from the LED driver to an auxiliary voltage, wherein the auxiliary voltage is independent of the output voltage received from the LED driver, and the auxiliary power system includes an output configured to provide the auxiliary voltage to an auxiliary device.
1 more element
An auxiliary power system, comprising:
- an input configured to receive an output voltage from a first output of an LED driver;
- a voltage converter configured to convert the output voltage from the LED driver to an auxiliary voltage, wherein the auxiliary voltage is independent of the output voltage received from the LED driver;
- and
- an output configured to provide the auxiliary voltage to an auxiliary device,
- wherein the auxiliary power system is configured for connection between the first output of the LED driver and a second output of the LED driver in parallel with an LED lighting element powered by the LED driver.
2 more elements
An auxiliary power circuit, comprising:
- a shunt component connected in series with a lighting device and a power source for powering the lighting device;
- a voltage regulation circuit connected in parallel with the shunt component, wherein the voltage regulation circuit includes:
- an input configured to receive an input voltage corresponding to a voltage drop across the shunt component;
- a voltage converter configured to convert the input voltage to an auxiliary voltage, wherein the auxiliary voltage is independent of the input voltage;
- and
- an output configured to provide the auxiliary voltage to an auxiliary device.
