Underwater lamp system based on power line carrier technology

Abstract

The invention relates to an underwater lamp system based on a power line carrier technology, and belongs to the technical field of LEDs. The system comprises an acquisition module, a light source, a starting circuit, a driving circuit and a control circuit, wherein the acquisition module is used for obtaining the type of water quality, and obtaining the distance data between a to-be-illuminated area and an underwater lamp through a range finder; the light source is used for emitting light beams of multiple primary colors; the starting circuit is used for providing a starting signal for the driving circuit; a segmented curvature compensation band-gap reference circuit is adopted as the driving circuit, and the driving circuit is used for providing driving current for the light source; the control circuit is connected with the acquisition module through a power line carrier line, the power line carrier line realizes a communication algorithm through establishing a temporary route between nodes, the control circuit determines driving current corresponding to each primary color light source according to the actual attenuation rate, and then mixed light formed by the light beams generated by the primary color light sources under the driving of the respective driving currents in the to-be-illuminated area is enabled to meet a preset chromaticity index.

Description

technical field [0001] The invention belongs to the technical field of light-emitting diodes, in particular to an underwater light system of power carrier technology. Background technique [0002] The underwater lighting equipment in the prior art is mainly used for night fishing and fishing, and usually adopts a colored light source to reflect the fluorescence of the buoy, or to attract fish schools. With the increasing ability of human beings to develop the ocean, the requirements for underwater lighting equipment are also getting higher and higher. [0003] In the underwater environment, there is a problem of communication difficulty in LED communication. If real-time control and acquisition of these control signals are required, a separate communication line is required, which will result in higher equipment and maintenance costs. However, power carrier communication That is, PLC is the abbreviation of English Power line Communication. Power carrier is a unique communi...
