Underwater spectrum adjustable lighting device and its spectrum adjustment method

Abstract

The invention discloses an underwater spectrum adjustable lighting device and a spectrum adjustment method thereof. The device includes a sealed cabin, a control module installed in the sealed cabin, a lighting module and a power supply module, and also includes a distance measuring module and a spectrum sensing module; The power supply module is connected to the control module and the lighting module respectively; the lighting module, the distance measuring module and the spectrum sensing module are all connected to the control module; the lighting module emits a light source under the control of the control module; the distance measuring module uses It is used to measure the distance between the target object and the lighting device; the spectrum sensing module receives the reflected spectrum, and transmits the spectrum information to the control module. The invention provides an underwater spectrally adjustable lighting device that can automatically adjust the spectral composition and light spot brightness output according to the distance in the visible light region (380nm-780nm), which provides a solution for the attenuation of light by the water body during underwater photography and other operations. solution.

Description

technical field

[0001] The invention relates to the lighting field, in particular to an underwater spectrum adjustable lighting device and a spectrum adjustment method thereof. Background technique

[0002] With the depletion of land resources, people turn their attention to the ocean. However, due to the inherent characteristics of water bodies, when light propagates underwater, the water body has an attenuation effect on light, and the attenuation will change with the wavelength and distance. During optical observation such as underwater photography, the image will be distorted, which brings great challenges to underwater optical observation and other operations. Therefore, it is necessary to design an underwater lighting system that can automatically adjust the spectrum according to the distance to obtain a specific target spectrum. The LED light source has a long life, low energy consumption, high luminous efficiency, and its spectrum is easy to adjust. development is p...
