Abstract: An electrical system can include a power supply coupled to an electrical load, where the power supply includes an AC/DC converter and a number of DC/DC converters, where the AC/DC converter provides raw DC power to the DC/DC converters, where the DC/DC converters receive the raw DC power and generate final DC power for the electrical load. The electrical system can also include a controller coupled to the power supply, where the controller selectively enables and disables the DC/DC converters.

Abstract: Safety improvements to Light Emitting Diodes (LED) are discussed herein. As the LEDs that are part of a luminaire heat up and cool down, the current supplied will be tuned to improve the safety of the luminaire to manage the levels of light and heat produced. At least one thermally active electrical component is incorporated into the LED load of the luminaire, which is communicated to an LED current control to signal when to adjust current levels providing by a driving circuit. Current is reduced when the temperature of the LED load exceeds a threshold, and or returned to an optimal current when the temperature no longer exceeds the threshold.

Abstract: An electrical system can include first and second electrical loads. The electrical system can also include a first power supply coupled to the first electrical load, where the first electrical load receives first power from the first power supply at a first time. The electrical system can further include a second power supply coupled to the second electrical load, where the second electrical load receives second power from the second power supply at the first time. The electrical system can also include a first switch disposed between and coupled to the first electrical load and the second power supply. The first switch, when in an open position at the first time, can prevent the second power from being received by the first electrical load. The first switch, when in a closed position at a second time, can allow the second power to be received by the first electrical load.

Abstract: The present disclosure relates to a fail-safe LED system including an LED circuit arrangement. The LED circuit arrangement includes a plurality of LED strings arranged in parallel with respect to each other. The LED circuit arrangement is supplied with electrical current from a constant current power supply. The fail-safe LED system includes structure for detecting a in at least one of the LED strings a failure that causes increased current to pass through remaining operational LED strings of the plurality of LED strings. The fail-safe LED system also includes a current correction string arranged in parallel with respect to the plurality of LED strings. When activated in response to the detection of a failure, the current correction string accommodates current from the constant current power supply such that the current passing through each operational LED string is reduced to a corrected current level.
