PMMA is a strong and lightweight material.
PMMA transmits up to 92% of visible light (3 mm thickness), and gives a reflection of about 4% from each of its surfaces due to its refractive index (1.4905 at 589.3 nm). It filters ultraviolet (UV) light at wavelengths below about 300 nm (similar to ordinary window glass).
Poly(methyl methacrylate) (PMMA), also known as acrylic or acrylic glass as well as by the trade names Plexiglas, Acrylite, Lucite, and Perspex among several others.
PMMA is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. Additionally, PMMA does not contain the potentially harmful bisphenol-A subunits found in polycarbonate. It is often preferred because of its moderate properties, easy handling and processing, and low cost.

A few years ago, these tiny lights set out to “conquer” displays and signal indicators. Much has happened since then. Today, LEDs are THE lighting medium for general lighting applications. Thanks to improved luminous efficacy and brightness, along with efficiency and long life, they have revolutionized the market.
Changing political and social conditions have contributed to the LED’s success. It meets the need for energy-efficient lighting solutions unlike any other light source. This is where the LED is groundbreaking.
You can find LEDs in all areas of life. Whether indoors or outdoors, for decorative or functional use - LEDs offer fascinating possibilities now and in future.
