Embodiment Construction

[0039] Below in conjunction with accompanying drawing, the implementation of the present invention is described as follows:

[0040] exist figure 1 Among them, the lighting source for adaptive chromaticity compensation for underwater photography consists of a pressure-resistant light box 1, a bracket 2, an array board LED light 3, a condenser lens 4, a control drive circuit 5, a pressure-resistant glass window 6, and a scene distance sensor 8 constitute.

[0041] Wherein, the pressure-resistant light box 1 can be set into a pressure-resistant box shape by strong and corrosion-resistant materials (such as stainless steel and other materials); a bracket 2 is arranged inside it, and an array board LED light-emitting lamp 3 is arranged on one side of the upper part of the bracket 2. The other side is provided with a condenser lens 4 . In order to enhance the lighting effect, the array board LED light-emitting lamp 3 can be set in a parabolic shape; it is composed of a plurality ...

Abstract

The present invention discloses a luminaier for underwater shooting self-adaptive chrominance compensating illumination light source, and is characterzed by that in compressive lamp box a support is set, one side of upper portion of said support is equipped with an array plate LED light-emitting lamp, and its another side is equipped with a condenser, the lower portion in the interior of compressive lamp box has a control drive circuit, a compressive glass window is positioned at condenser position, and a scene ranging sensor is placed in the lower portion of interior of the compressive lamp box, and the control drive circuit is respectively connected with scene ranging sensor and array plate LED light-emitting lamp, in which the control drive circuit uses the microprocessor to respectively connect with scene ranging sensor circuit, chromatic ratio circuit and memory and uses the power amplification drive circuit to respectively connect with chromatic ratio circuit and array plate LEDlight-emitting lamp. The interior of microprocessor also has the control software for underwater shooting self-adaptive illumination light source.

Description

[0001] Technical Field The present invention belongs to the category of optical equipment, and in particular relates to camera lighting lamps and controls. Background technique [0002] Underwater photography is a commonly used technical means to explore rivers, ocean underwater geography, biology, physics, chemistry, mineral deposits, etc. Usually due to the chemical composition of water, especially seawater, optical refraction, reflection and other reasons, the quality of underwater photography is not ideal, and the main factors affecting the degradation of underwater photography quality are the following aspects. [0003] (1) Absorption: Since water absorbs light much more than air, the viewing distance is only about 1 / 1000 of that in air. Below the depth of 100 meters, it is basically a dark world. [0004] (2) Scattering: Due to the strong scattering of light by various particles in the water, the water appears hazy, and ...
