## Abstract

Devices and methods for protecting against a surge in a luminaire are provided. For example, a controller for use with a luminaire is provided. The controller can include a first circuit configured to sense a surge in voltage or current. The controller can further include a second circuit configured to switch a relay in response to the first circuit having sensed the surge in voltage or current.

## Claims

### Claim 1

A controller for use with a luminaire, comprising:
a surge detection circuit configured to sense a surge in voltage or current;
a relay control circuit configured to repeatedly switch a relay in response to the surge detection circuit having sensed the surge in voltage or current;
the controller including a first circuitry configured to measure at least one electrical parameter of the surge, and a second circuitry configured to transmit the at least one electric parameter of the surge to a remote device; and
the second circuitry configured to send a signal after the surge is sensed to a direct current (DC) converter circuit to shut down an alternating current output voltage supply internal to the DC converter circuit.

### Claim 2 (depends on 1)

The controller of claim 1, surge detection circuit includes a transient voltage suppression diode.

### Claim 3 (depends on 1)

The controller of claim 1, wherein the surge detection circuit includes a flyback diode.

### Claim 5 (depends on 1)

The controller of claim 1, wherein the at least one electrical parameter includes an amplitude of the surge.

### Claim 6 (depends on 1)

The controller of claim 1, further comprising a third circuitry configured to log the at least one electrical parameter of the surge.

### Claim 7 (depends on 1)

The controller of claim 1, further comprising a fourth circuitry configured to log historical data indicative of past surges.

### Claim 8

A controller for use with a luminaire, comprising:
a surge detection circuit configured to sense a surge in voltage or current; and
a relay control circuit configured to switch a relay in response to the surge detection circuit having sensed the surge in voltage or current;
the controller including a first circuitry configured to measure at least one electrical parameter of the surge, and a second circuitry configured to transmit the at least one electric parameter of the surge to a remote device; and
the second circuitry configured to send a signal after the surge is sensed to a direct current (DC) converter circuit to shut down an alternating current output voltage supply internal to the DC converter circuit.

### Claim 9 (depends on 8)

The controller of claim 8, surge detection circuit comprising a transient voltage suppression diode.

### Claim 10 (depends on 8)

The controller of claim 8, wherein the surge detection circuit includes a flyback diode.
