Abstract: A photo switching device includes first and second terminals respectively coupled to a power source and a load. A bi-directional current routing circuit including a rectifying bridge is connected to the first and second terminals to receive electricity from the first and second terminals and has positive and negative output terminals. A switching/driving circuit is connected between the positive and negative output terminals for selectively conducting an output current of the bi-directional current routing circuit from the positive output terminal to the negative output terminal. The switching/driving circuit includes a silicon controlled switching device having a gate coupled to and controlled by a controlling circuit to switch between open condition and closed condition. The controlling circuit includes a photo detecting device connected to a gate of a gate controlled device. The gate controlled device has an output coupled to and controlling the gate of the silicon controlled switching device.

Abstract: A lighting string controller includes a power supply circuit that converts an alternate current (AC) input into a direct current (DC) output and includes an impedance buck circuit for expanding the applicable voltage range of the AC input and supplying a stable DC power to a display control circuit, a drive circuit and at least one lighting string. The display control circuit operates the lighting string through the drive circuit and the display control circuit controls time period within which the lighting string is in full lighting condition to allow a lighting string that is of a high power consumption to fully light in a short period of time. The display control circuit also functions to control operation modes of the lighting string, including lighting ON/OFF, interrupted lighting, gradually brightening/dimming, cyclic lighting, and alternating loop flashing, and can be controlled by a control switch or a remote control to switch among the operation modes. As such, a lighting string controller that is free of transformer and that is compact is size is realized.

Abstract: A liquid-proof enclosure includes first and second casing members engaging each other to define an interior space for receiving, retaining and protecting an electrical device. Each casing member has a mating flange engaging each other to encase the electrical device. A rib is formed along the mating flange of the first casing member and a corresponding slot is defined along the mating flange of the second casing member for receiving and engaging the rib thereby attaching the first and second casing members together and increasing length of a possible leakage path between the first and second casing members. An opening is defined between the first and second casing members. At least a circumferential slot is defined along a circumferential wall of the opening. A cable retainer retaining a cable forms ribs received in the slot of the opening for attaching the cable retainer to the first and second casing members and to prevent liquid leakage into the enclosure.
