High Efficiency COB LED Lens No Light Pollution For 10W LED Down Light

High Transmittance 93% COB LED Lens 15 Degree For 10W Led Down Light

How do I get the tightest spot pattern possible?

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.

1, The smaller the size of the die the tighter the spot. For example, to get the tightest spot with our LEDs

you would want to use the Cree XP-E LED (smallest size die) and the 26mm plain tight lens (largest diameter optic).

2, 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.

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.

Lenses are designed for use with single or multiple LEDs. This includes LED modules or strips.
They sit over the LEDs to create the desired lighting effect.
