It is believed that with the rapid progress of LED lighting technology and the increase of consumers' trust in LED, the popularization of LED lighting lamps in the future will not be long. LED lighting lamps uniformly use LED as light source, which has more advantages than ordinary lighting lamps. Energy saving and environmental protection needless to say, its high efficiency and long life are in line with people's use psychology. In the past two years, LED lighting has developed rapidly in the commercial and industrial fields. However, with the progress of technology, LED lighting has begun to enter the underwater lighting field, and achieved good results. At present, there are two main factors that hinder LED lighting products from entering the civil market: On the one hand, because the society's awareness of LED technology and products is still in the primary stage, LED lighting lamps should be popularized, improving consumer awareness is still the key. On the other hand, because the price of LED lighting lamps is higher than that of traditional lighting products, most ordinary users see short-term cost benefits and will not put long-term energy-saving benefits in the first place. Therefore, the penetration rate of LED lighting has been unsatisfactory. In order to improve the penetration rate of LED lighting, we must start from these two aspects. While popularizing LED knowledge, we should gradually reduce the price of LED lighting by means of technology to promote productivity, and then promote the popularization and application within the scope. LED lighting will be the mainstream of lighting design in the future and play an increasingly important role. The market share of lamps and lanterns is increasing. As for the underwater lamp, the ordinary lamp is switched to the LED straw hat lamp, and then the LED straw hat lamp is updated to the LED patch lamp head. A revolutionary reform has made the LED underwater lamp stand out in this reform, it has become a new generation of new stars, effectively prolonging its service life, effectively reducing power consumption, effectively increasing brightness, and more effectively realizing more color changes, let China's underwater lamps go to the whole country at a higher speed and to the whole world. In the future underwater environment, LED underwater lamps will continue to be reformed and upgraded to a colorful underwater world.
