The main task of LED lenses is to improve the efficiency of the LEDs and the direction of the light flux. Lenses are usually of two types: outdoor lenses with a wide dispersion angle and lenses designed to organize illumination. The second type of lens is used to provide lighting for shop windows, advertisements, sales areas, residential buildings, apartments, etc. and is available with and without built-in holders.
The material for the manufacture of LED lenses is high-quality glass of increased strength and high degree of transparency. The main characteristic influencing the choice of lenses is the angle of diffusion of the light flux, which depends on the diagram. If the diagram is narrow, then the scattering angle is small (5-20 degrees), and with a wide diagram, it is correspondingly large (more than 50 degrees).
When purchasing an LED lens, it must be borne in mind that models with a wide diagram provide a lower level of illumination, as well as the relationship between the intensity of light and the area of illumination. LED lenses increase the efficiency of light transmission by more than 90%, and also allow you to adjust the direction of the light flux. This is what explains such a high popularity and demand for LED lenses in industry and everyday life.
