Life Jacket Light Concept
The marine life jacket light (also called the life jacket position indicator light) is a life saving device equipped on a life jacket, and is used in combination with a life jacket. In general, the lifejacket light is composed of the following parts, including a power source, a light clip, a light holder, a bead and a light cover, and the light clip and the light holder are embeddedly engaged, and the light cover has a main convex lens at the front end and a side front end. The annular auxiliary convex lens has a fixed distance hole on the light holder, a fixed distance rod frame on the light clip, and a fixed distance rod on the fixed distance rod frame. According to national standards, existing lifejacket light are required to increase the intensity of illumination in the direction of illumination under conditions of very small power supply capacity. Since there is an aura around the center of the illumination direction, the chance of being discovered by nighttime water users is increased. The lifejacket light is suitable for indicating the position of the life jacket or lifebuoy at sea to the ship's drowning personnel and rescuers at night for fast rescue purposes.
