Abstract: The present invention discloses an LED string lamp apparatus which includes plural LEDs serving as a light source, wherein any two neighboring LEDs are connected together through a lead wire. In addition, plural insulation sheaths, a quantity of which matches with that of the LEDs, are used to support the LEDs; whereas, plural floor plugs, a quantity of which matches with that of the LEDs, are used to fix the LED string lamp. Additionally, an LED assembly, which is formed by the insulation sheath and the LED, can be movably installed on the floor plug. The LED string lamp provided by the present invention can be hung on tree branches or a fence and can be fixed on a ground or a lawn, which expands the area of application.

Abstract: The present invention discloses a solar lamp which includes a bottom seat, a housing, a solar cell, a control circuit board, rechargeable batteries and LEDs. The solar cell is installed at a top of the housing, the control circuit board, the rechargeable batteries and the LEDs are installed inside the housing, the top of the housing is provided with a top ornament and a lower side of the housing is supported by the bottom seat. The present invention enables a solar cell to have a larger power and the top ornament can compensate for incompleteness of the shape.

Abstract: A light tube with an LED light source includes a casing, a control circuit board, an LED circuit board inside the casing, and LEDs coupled to the LED circuit board. Input and output ports of the control circuit board are connected to pins of the casing via an input line and to the LED circuit board via an output line, respectively. A power module and a control module are provided on the control circuit board and at input and output ends thereof, respectively. The power module includes first and second filter capacitors and a rectifier bridge circuit. The first and second filter capacitors straddle and connect with input and output ends of the rectifier bridge circuit, respectively. The output end of the rectifier bridge circuit connects with the control module. Thereby, high-frequency AC from an electronic ballast or low-frequency AC is converted to DC for the LEDs.
