Systems and methods for protecting electrical wire connections from overheating
First Claim
1. A system for protecting from overheating a physical electrical wire connection formed from a plurality of electrical wires that are part of an electrical circuit inside a ceiling light fixture, comprising:
- a ceiling light fixture housing configured to be attached to a ceiling-mounted junction box that contains;
a twist-on wire connector configured to maintain the physical electrical wire connection, wherein the twist-on wire connector connects a conductor of a wire of the light fixture to a building power conductor, wherein the conductor supplies power to the light fixture, and wherein the wire of the light fixture is formed from the conductor and insulation;
a temperature sensor that is separate from the twist-on wire connector, that is configured to detect the temperature of the conductor, and that produces a first signal in response to a temperature of the conductor;
an operational amplifier coupled to the temperature sensor that produces at a first output a second signal having a first value when the temperature exceeds a temperature value and a second value when the temperature is less than the temperature value; and
a relay having a control input coupled to the second signal and having a switch coupled to the electrical circuit that opens the electrical circuit in response to the second signal having the first value.

Abstract
Systems and methods for protecting electrical wire connections from overheating are provided. In some embodiments, methods for protecting electrical wire connections from overheating are provided, the methods comprising: detecting a signal responsive to a temperature of an electrical wire connection using a temperature sensor; comparing the signal to a threshold; and disconnecting power to a circuit when the comparison indicates that the temperature is over a given value. In some embodiments, systems for protecting electrical wire connections from overheating are provided, the systems comprising: a temperature sensor that detects a signal responsive to a temperature of an electrical wire connection using a temperature sensor; an operational amplifier that compares the signal to a threshold; and a relay that disconnects power to a circuit when the comparison indicates that the temperature is over a given value.
