PMMA Plastic Landscape Light Lenses , 20 Degree Cree Led Lens

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.

• High power LEDs are constantly improving and becoming smart options for a wide range of applications.
• As we have stated above, for a lot of these applications, such as interior spot/down lighting, street lighting, architectural lighting and spot lighting, the emitter and primary optic on their own cannot deliver enough intensity to the target surface.
• We dove into emitters output above but another way of describing it is that emitters give off a Lambertian light distribution.
• This basically means that the brightness to an observer is the same, regardless of the observers position.
• If you have ever seen a bare emitter light up, you can see this instantly. Even if you are far to the side, you can still see that the light source is extremely bright, it will probably even bother your eyes to look at. The problem is that this light is just thrown out there with nothing harnessing the rays.
