Diving flashlight research background
With the improvement of human living standards, the search for the mysterious sea, desire, scuba diving also gradually from every coastal city in the world, individual regions development, to the lake city diving club to flourish, because underwater light is dim, all people are looking forward to see the bottom of the sea, a waterproof properties is good lighting tools become urgent need!Aquatic class seafood has become people to enjoy food, so fishing workers is also more and more!So fishing, scuba diving the development of the project and underwater salvage underwater operations are promoting factor of the diving lighting!
There is demand there will be a market, the human life in the past lighting flashlight, unceasingly take all kinds of technology improve the waterproof performance of the flashlight!Finally diving flashlight was born!Due to strong light flashlight, all kinds of light of LED light source in the development of diving flashlight!
2 the development status quo of diving flashlight
The initial diving flashlight for push button switch, then thought of the circular, at present, a lot of diving flashlight adopts toggle switch or rotary switch!Diving also reached 30 meters, 60 meters, 100 meters, 150 meters, 200 meters, etc
