3030 Chips PMMA LED Lens 18 In 1 Narrow Beam Angles For LED Spotlights

24 Degree 3030 LED 18 In 1 Optical PMMA LED Light Lens For Spotlights

How do secondary lens optics work?

LEDs generally emit light at a 120-degree viewing angle. LED applications that require more focused

light often use a secondary optic that is placed over the LED, which internally reflects light into a spot, medium spot, wide spot or elliptical spot pattern.

• Most optics are cone shaped and need an optic holder to hold the lens in place over the LED.
• The lens itself clips securely into the holder, but the holder does need to be externally adhered.
• 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.

Beam Angle:
This describes the angle over which the light is distributed. Lenses and reflectors can be used to help create your desired beam angle.

Narrow beam angles, for example 40°, have a tight beam of light and are ideal for spotlights. Wide

beam angles around 120° have a larger coverage for wide area lighting.
