Underwater light source device with hairbrush and diaphragm

Abstract

The invention discloses an underwater light source device with a hairbrush and a diaphragm for an underwater optical experiment with a light source. The underwater light source device comprises a light source, a stepping motor, a rotary shaft, a diaphragm system and an oscillating bar. The rotary shaft is connected to the output shaft of the stepping motor, the oscillating bar is arranged on the rotary shaft, and the rotary shaft rotates to drive the oscillating bar to control the diaphragm system to be turned on and off; the diaphragm system is attached to the light source for controlling illumination of the light source to pass through and to not pass through and clean the surface of the light source. The underwater light source device disclosed by the invention effectively avoids dangers due to instable working state as the light source is turned on and off when the power of the light source is relatively great (greater than 100W) and relatively large current on and off, the time required by waiting the working state of the light source to be stable is shortened, and the experimental efficiency is increased. Moreover, the surface of the light source is immediately cleaned to prevent attachments such as water drops and floats on the lamp wall from affecting illumination, so that the result obtained from the underwater experiment is more accurate and the experimental flow is safer.

Description

technical field [0001] The invention relates to underwater light source technology, in particular to an underwater light source device with a brush and a diaphragm. Background technique [0002] When scientific researchers do underwater optical experiments, they often need to measure the background light when there is no light and the experimental data when there is light. However, it takes a certain time for a high-power light source to reach a stable working state when working underwater. Choosing to turn on and off the light source from time to time will not only waste time and reduce efficiency, but also cause unstable working conditions of the light source and bring experimental errors; when working underwater, water droplets or floating objects often adhere to the lamp wall, which will also cause It is very inconvenient to take out the underwater light source to the water surface for cleaning due to the change of the light source illumination condition and cannot be do...

[0002] When scientific researchers do underwater optical experiments, they often need to measure the background light when there is no light and the experimental data when there is light. However, it takes a certain time for a high-power light source to reach a stable working state when working underwater. Choosing to turn on and off the light source from time to time will not only waste time and reduce efficiency, but also cause unstable working conditions of the light source and bring experimental errors; when working underwater, water droplets or floating objects often adhere to the lamp wall, which will also cause It is very inconvenient to take out the underwater light source and clean it on the water surface due to the change of the light source and illumination conditions, and it cannot be done in time

[0003] So far, there is no underwater high-power light source with a brush and diaphragm that can clean up the lamp wall attachment in time and measure the background light when the light source is turned on.
