Optics for LEDs are used to focus the luminous flux emitted by the diode. To increase the efficiency of the lighting fixture, lenses with a predetermined light scattering angle are used for the diodes.
The use of such optical systems for LEDs allows reducing the LED's emission angle, collecting the entire luminous flux in the required direction, and distributing it evenly over the emission area.
With the help of optics for LEDs, several different output beam patterns can be generated: narrow, medium, elliptical, and wide beams.
A correctly selected optical system and its placement distance from the light source (diode) yield maximum efficiency in using the luminous flux.
The material for LED optics is high-quality glass, acrylic, or polycarbonate.
