Laser marine navigation illuminating lamp based on three primary colors

Abstract

The invention relates to a laser marine navigation illuminating lamp based on three primary colors, and belongs to the technical field of optical systems. According to the laser marine navigation lamp illuminating lamp system, the three semiconductor lasers which respectively generate three primary colors of red, green and blue are adopted as light sources, light is emitted to the three different parts and finally synthesized into white light; the advantages of high monochromaticity, high brightness, small size, light weight, high integration, long irradiation distance and the like of laser are fully utilized, and on the premise that the design requirements are met, the lighting effect needed by marine navigation lamp lighting is formed at a time, and the light color is adjustable; and a cut-off line type is formed mainly through laser direct writing and other methods in the machining aspect, the design thought of a traditional navigation lamp is broken through, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of optical systems, and relates to an application in ship lighting, in particular to a laser marine navigation lighting based on three primary colors. Background technique [0002] Ship lighting is installed on the head of the ship and is mainly used for lighting at sea at night. Navigation lights are divided into near-distance lighting and long-distance lighting. The low beam should have sufficient lighting without causing glare, and the high beam should have good lighting. [0003] The current navigation lighting, especially the lighting of ships, is mainly divided into three parts: light source, reflector and light distribution mirror. Light distribution requirements. From a specific design point of view, the light source mainly uses halogen lamps, xenon lamps (HID) and a new generation of light source LEDs (light-emitting diodes); the free-form surface lens designed by the light distribution mirror sol...

AI Technical Summary

Problems solved by technology

However, there are some disadvantages in the above design scheme: for example, the chromaticity of a single LED cannot meet the standard of the existing ship lighting, and the reflector cannot meet the light distribution standard due to the limitation of its own geometric shape. The specific performance is that the high beam is not enough Far and near beams are prone to glare. Although the free-form surface method solves the glare problem and has the advantages of high design freedom and small size, its design and processing are more complicated than the above methods
