A start-up circuit includes a switching-device control circuit arranged to receive an input voltage and to provide a switching-device control signal, a switching device arranged to be controlled by the switching-device control signal and to provide a start-up signal, a power-converter control circuit arranged to receive the start-up signal and to provide a power-converter control signal, and a power converter arranged to receive the power-converter control signal and to provide an auxiliary output signal. The switching control circuit is arranged to receive the auxiliary output signal such that, when the auxiliary output signal reaches a predetermined level, the switching-device control circuit stops providing the switching-device control signal.

The present disclosure relates to a programmable underwater lighting system for pools and spas. A plurality of underwater lights, each having a plurality of LEDs for producing light of various colors, a microprocessor for controlling the plurality of LEDs, and a memory in communication with the microprocessor containing one or more stored control programs, allow for the generation of various lighting effects in a pool or spa. A central controller is provided in communication with the plurality of underwater lights, and allows a user to define or select a desired lighting effect (such as a sequence, a fading effect, a “moving” color pattern, etc.) using a display and a keyboard. Optionally, a handheld remote control could be provided, in wireless communication with the central controller, for allowing a user to remotely control the plurality of lighting fixtures. When a desired lighting effect is defined by a user, the central controller transmits an instruction to each of the plurality of underwater lights instructing each light to execute a specific stored control program in its memory to produce the desired lighting effect. Each of the lights could be in communication with the central controller using a power line and an associated power line carrier data protocol, and each light could be provided with a thermal management system for monitoring the operating temperature of the light and automatically adjusting the brightness of the light to prevent dangerous temperatures.

A synchronous rectification circuit includes a transformer receiving an input voltage at a primary side and outputting an output voltage at a secondary side and a controller arranged and programmed to operate independently from the input and output voltages. The controller preferably outputs control signals to switching logic devices, the switching logic devices being arranged to output timing signals to drive individual synchronous rectifiers included in the secondary side of the transformer. The synchronous rectification circuit includes at least one logic gate which receives the control signals output from the controller and supplies clock signals to the switching logic devices, the clock signals being generated by the at least one logic gate based on the control signal and driving devices arranged to receive the timing signals from a respective one of the switching logic devices, the driving devices driving the synchronous rectifiers in accordance with the timing signals.

A solder composition includes about 4% to about 25% by weight tin, about 0.1% to about 8% by weight antimony, about 0.03% to about 4% by weight copper, about 0.03% to about 4% by weight nickel, about 66% to about 90% by weight indium, and about 0.5% to about 9% by weight silver. The composition can further include about 0.2% to about 6% by weight zinc, and, independently, about 0.01% to about 0.3% by weight germanium. The composition can be used to solder an electrical connector to an electrical contact surface on a glass component.
