Lamps for underwater lighting and its dimming method based on the principle of transmission turbidity measurement

Abstract

The invention discloses a lamp for underwater lighting based on the principle of transmission turbidity measurement, and relates to a lamp for underwater lighting. It includes lamp body, lamp bracket, reference infrared light source, infrared filter, infrared photoelectric sensor, cable connector, LED driver module, LED lamp, lampshade shell, main circuit board, signal detection and processing module, constant current source drive, power supply Module, microcontroller, one end of the main circuit board is electrically connected to the signal detection processing module, the other end is electrically connected to the constant current source drive, the LED driver module is electrically connected to the other end of the main circuit board, and the infrared photoelectric sensor and the signal detection processing module are free. The terminal is electrically connected, and the reference infrared light source is electrically connected to the spare terminal driven by the constant current source. The invention can automatically adjust the luminous flux of the lamp, can make the illuminance of a specific working surface of the underwater lighting constant, and can improve the quality of the underwater lighting. It also relates to the dimming method of the underwater lighting fixture based on the transmission turbidity measurement principle.

Description

technical field [0001] The invention relates to a lamp for underwater lighting, in particular to a lamp for underwater lighting based on the principle of transmission turbidity measurement. The invention also relates to the dimming method of the underwater lighting fixture based on the transmission turbidity measurement principle. Background technique [0002] Underwater lighting, especially deep water lighting, is widely used in underwater archaeology, cultural relics protection, underwater biological research, underwater scientific experiments, underwater safety protection and other fields. Because water has an obvious attenuation effect on light, and is affected by factors such as water environment changes and water turbidity, underwater lighting is more difficult than ordinary lighting. At present, underwater lighting can only meet the needs of ordinary observation in most cases, and the lighting control method is relatively simple. Most underwater lighting fixtures can...

AI Technical Summary

Problems solved by technology

At present, underwater lighting can only meet the needs of ordinary observation in most cases. The lighting control method is relatively simple. Most underwater lighting fixtures cannot be dimmed. And it is adjusted manually according to the on-site environment or by the computer according to the preset instructions. The dimming method cannot be automatically adjusted according to the state of the water environment, which will affect the actual effect of underwater lighting.
