Diving headlamp is one of the commonly used equipment in diving sports, which can provide a light source, so that divers can clearly see the surrounding environment in the deep sea. The optical component of the diving headlamp is an important part of determining its light effect, of which the lens and the light cup are two common optical components. So, what is the difference between the use of lenses and light cups in diving headlamps?
First, let’s look at the basic concept of a lens and a light cup. A lens is an optical element, “which is able to focus light. It is able to reflect or diverge light, thereby changing the direction and intensity distribution of the light.” The light cup is an optical reflector and is focused on a specific area to increase the brightness and focus of the light.
In LED rechargeable headlamps, the lens and light cup function differently. The lens is mainly used to adjust the propagation direction and intensity distribution of the light, so that the light can better illuminate the front of the diver. The lens can be designed according to needs, for example, the convex lens can focus the light into a small range, thereby improving the brightness and focusing effect of the light; Concave lenses can spread the light, allowing the light to illuminate the surrounding environment more widely. The selection and design of the lens needs to take into account the needs of divers for outdoor led headlamp and the characteristics of the diving environment.
The light cup is mainly used to improve the brightness and focusing effect of the light. The light cup can reflect and focus the light into a specific area, making the light more concentrated and intense. The design and material selection of the light cup have an important influence on the focusing effect of the light. In general, the deeper the shape of the light cup, the better the focusing effect of the light, but at the same time, it will also lead to a narrower range of light exposure. Therefore, the selection of light cups needs to be balanced according to the needs of divers for diving headlamps and the characteristics of the diving environment.
The lens is mainly used to adjust the propagation direction and intensity distribution of the light, so that the light can better illuminate the front of the diver. The light cup is mainly used to improve the brightness and focusing effect of the light, making the light more concentrated and intense. The choice and design of the lens and light cup needs to be weighed against the needs of the USB rechargeable headlamp and the characteristics of the diving environment.
In addition, the lens and the light cup also have a certain difference in the light effect of the rechargeable sensor headlamps. The lens diving headlamp can change the focusing effect of the light by adjusting the focal length and shape, so that the light of the diving headlamp can better illuminate the front of the diver. The light cup diving headlamp mainly improves the brightness and focusing effect of the light of the diving headlamp by reflecting the light and concentrating it into a specific area. Therefore, the lens diving headlamp and the light cup diving headlamp have different characteristics and advantages in the light effect.
In summary, there are certain differences in the application of lenses and light cups in diving headlamps. The lens diving headlamp is mainly used to adjust the propagation direction and intensity distribution of the light, so that the light of the diving headlamp can better illuminate the front of the diver; The light cup waterproof headlamp is mainly used to improve the brightness and focusing effect of the light. The choice and design of lens and light cup headlamps need to be balanced according to the needs of the diver and the characteristics of the diving environment. Whether lens diving headlamps or light cup diving headlamps, they are indispensable optical components in diving headlamps, and their reasonable application can improve the safety and diving experience of divers.
