Abstract: A remote controlling device includes a micro-controller; a transmitter coupled to the micro-controller to selectively transmit a control signal that controls the lighting of a lamp string, the transmitter comprising an encoder for coding the control signal; a preset lighting mode memory coupled to the micro-controller to store preset lighting modes; and lighting control program memory coupled to the micro-controller to store lighting control programs, each comprised of at least one lighting mode selected from the preset lighting mode memory. A user may operate a plurality of selection switches to select the preset lighting modes and the lighting control programs from the memories. Actuation of a transmission button allows for transmission of the control signal that carries the lighting control program selected from the lighting control program memory toward a receiver of the lamp control module of the lamp string in a wireless manner for controlling the lighting of the lamp string.

Abstract: A tubular decoration light string comprising inner insulator and outer insulator, said decoration light string equipped and fixed an inner insulator, said inner insulator and decoration light string to be sealed within an outer insulator, and to form a longitudinal direction hollow in said outer insulator, increasing an effect of reflection and refraction of light.
