Technical Examples
- A lamp display system (10) is disclosed for displaying various lamp shades (11) with various lamps (12). The lamp display system includes a rear wall (13), a top shelf (14), a middle shelf (15), and a bottom shelf (16). The system also includes a plurality of lamp shade mounting arms (18). Each mounting arm has an arm portion (19) extending to a light bulb socket (21), and a harp (22). Each mounting arm may be mounted to an elongated mounting bracket (23) which in turn is mounted to the rear wall. The mounting arms are also staggered in height and/or distance from the rear wall to allow for the compact display of many lamp shades.
- A barcode symbol having an encoded symbology is provided with color or shades of gray to add additional information at the time of printing. The color or shades of gray provides the current barcode symbology with a third dimension of information. The color or shades of gray can encode information over a specific one-dimensional or two-dimensional symbology. White spaces can be replaced with colors or shades of gray to add coded information to the standard one-dimensional and two-dimensional codes. The number of colors and how they are distributed or arranged can provide the basic backbone of information. A barcode reader that can detect the different color spectrums, can be employed to decode the information. Furthermore, color is not limited to white spaces, but can be implemented into black spaces. Additionally, colored background information can provide additional information to the current symbology.
- In a backlight apparatus for an LCD, a plurality of bar-shaped first LED light sources are arranged on the reflective plate to laterally emit light. A plurality of light shades are arranged above the first light sources. A transparent plate is placed above the light shades. Scattering patterns are formed in the bottom of the transparent plate in positions corresponding to the light shades. A bar-shaped second LED light source is arranged at a side of the transparent plate to emit light into the transparent plate. The light source arranged at the side of the transparent plate prevents the formation of dark areas as a problem in the prior art, thereby enhancing the entire uniformity of light. Then, the backlight apparatus can be maintained thin even when applied to a large-sized LCD.
