ABSTRACT:
The invention relates to a tubular lamp, particularly relates to a high-intensity parapet lamp for road or bridge, which can displays various colors and is controlled by computer program.
Most of conventional parapets for road or bridge are of metal construction, and made of steel tubes with rectangular or circular cross-sections. They are often coated with various colors in order to attract people's attention. At night, since only when they can reflect light, can they be seen by people, it is difficult for them to be noticed. Therefore, they can not effectively prevent traffic accidents.
The object of the invention is to make the parapet of luminous tubular lamps controlled by computer program; while they are lit up at night, the light emitted by the parapet tubular lamps will produces a flowing effect which can indicate the direction.
Above object is achieved by following full color parapet lamp for road or bridge, consisting of an outer tube, an inner tube through which wires can pass, sealing brackets and a controller, characterized in that the cavity of the lamp is sealed with soldered illuminants and light-reflecting circuit boards insider; the power supply wires pass through the inner tube and the ends of the wires are connected to multi-contact connector assemblies. Moreover, the said outer tube of the lamp is made of red and/or white tube with red and/or white illuminants inside; the said illuminants are of homochromatic or tricolor bulbs, light-emitting diodes, other light sources or their combination selectively; the said controller is a single controller or a main controller with several sub-controllers selectively.
The advantages and effects of the present invention are as follows:
1. Instead of the light-reflecting parapet, the parapet for road or bridge is made of light-emitting parapet.
2. Computer program is used for making the parapet to indicating the direction for people and cars.
3. The lamp is provided with an inner tube through which power supply wires can pass, so that there is no wires outside and the lamp has a tidy and good appearance. The lamp is easy to assemble and disassemble as well.
4. The outer tube can be of various colors and can emit light of fill color.
