28 in 1 Vertical Multi Lens LED Light Lens With PCB Module For Road Lamp

Optical efficiency is determined by measuring the ratio of light collected after the optic and dividing

by the total amount of light without an optic directly at the LED source.

A Lens is a Transmissive Optical Device that affects the focus of a light beam through refraction.

• A simple Lens consists of a single piece of material, while a compound Lens consists of several simple lenses (elements), usually along a common axis.
• Optics allow you to control your illumination pattern, either diffusing it or focusing it as your application requires. Secondary LED Optics provide a standard LED with collimation for spot, medium, wide and elliptical illumination patterns.
• In the case of LED stars, optic holders have four legs that sit down into the grooves of the star board. Triple LED stars are built with three holes in the star board for the legs of the optic.

Delivery and Shipping:

In general, when talking about lens optics the larger the optic the easier it is to collimate light into a

tighter pattern. Another consideration when trying to achieve a tight spot is the size of the LED die.

The smaller the size of the die the tighter the spot.

LED lenses come in various shapes and sizes, for example round, square and hexagonal.

Common lens materials include plastic and silicone. Therefore some are rigid and some are flexible.
