A system for creating a flickering effect comprises a light communicating cable, at least one light receiving cable secured on a rotatable mount rotatable about a horizontal axis, a light diffuser element in communication with the at least one light receiving cable and a rod connected to the diffuser element for causing rotary motion of the light diffuser surface about the horizontal axis.

Disclosed herein is a light emitting diode (LED) device. The light emitting diode device comprises a package formed with a terminal for applying an electrical signal, one or more LED chips mounted on the package such that the LED chips are electrically connected to the terminal, a lens formed to surround the LED chips on the package for changing path of light emitted from the LED chips to the horizontal direction with the difference of the refraction rates of the media, and a reflector formed on the lens for reflecting the light, emitted above the lens without being refracted in the horizontal direction at the lens, to the horizontal direction. The LED device reflects the light, which is deviated from the optical design range of the lens and emitted above the lens, back to the lens, thereby preventing the hot spot from being generated, and enhancing horizontal emission efficiency of the light.

The present invention relates to a light emitting medium which includes a container and a liquid core. In accordance with an important aspect of the invention, the liquid core includes an aqueous solution or mixture of a water-soluble polymer. The refractive indices of the liquid core and that of the container may be different. However, the aqueous solution or mixture may have a lower or higher refractive index than that of the container. The mixture may be completely transparent or translucent and have a color other than clear. The container may be of any material that is translucent or transparent and be of any color.The raw materials for the light emitting medium in accordance with the present invention are less costly than known light guides and offer numerous advantages when compared to other illumination light guides. Water advantageously is a major raw material of the present invention. The water-soluble polymer component may be used in relatively minute amounts. For example, a liquid core in accordance with the present invention can be formed from up to 99.9% water and 0.01% water-soluble polymers, although higher amounts of water-soluble polymer may result in better characteristics. The container material may be formed from typically available polymers, such as polyvinyl chloride, acrylics and methacrylics or polyolefins and be formed by commonly known processes, such as extrusion, blow-molding and injection molding.In one embodiment of the invention, the light emitting medium in accordance with the present invention is combined with at least one light emitting diode (LED), a power source and a switching device to form a self contained illumination device. In another embodiment of the invention, images are formed on the container in different colors. Multiple LEDs of various wavelengths are selectively illuminated to simulate motion of the images.

A decorative base paper or a preimpregnated decorative base paper is finished with an ink absorbing layer for printing by the ink-jet method.

A base station configured to communicate with a mobile station includes a controlling-information transmitting unit and a receiving unit. The controlling-information transmitting unit is configured to transmit to the mobile station as a set of controlling information, an information set indicating an environment of a cell which is resided by the mobile station, or an information set indicating power of interference from surrounding cells, or an information set indicating a condition of propagation channel. The receiving unit is configured to receive a signal transmitted from the mobile station, based on said set of controlling information, via a variably-controlling process of a spreading factor and a number of chip repetitions.
