WeeTect offers UV-resistant polycarbonate sheet for LED lenses and SSL design

April 14, 2016
Songjiang, Shanghai - WeeTect has announced a new UV resistant polycarbonate sheet for LED lenses and SSL design. LED is an advanced lighting technology that features different designs and functionality.

WeeTect has further expanded its range of products for LED lighting systems and SSL design. The company had launched a flame retardant PC sheet, abrasion resistant coating and anti-fog coating. All these are designed for original equipment manufacturers (OEM) who strive to meet the dynamic demands of consumers.

The UV resistant polycarbonate sheet is a perfect choice for LED lighting fixtures as it balances the following key features:

1. Light transmission; it maximizes light transmission and minimizes hot spots.
2. Expanded diffusion levels; this enables designers to create more efficient fixtures
3. Outstanding outdoor weathering performance.
4. Enhanced aesthetics.

Balancing the four features results in an efficient and reliable LED lenses and lighting fixtures.

What is unique about UV resistant polycarbonate sheet for LED lighting fixtures?
The WeeTect R&D team wrote a report on the effects of subjecting polycarbonate sheets to a continuous light. Degradation of polycarbonate was a major area of concern. The company, through advanced manufacturing technique has introduced a superior UV resistant PC sheet. This is specifically for LED systems.

In all lighting fixtures, the polycarbonate material is subjected to UV light from two main sources:
1. LED; a blue LED, coated with phosphor (yellow) will produce white light. This light has negligible UV radiations thus, may not affect the polycarbonate sheet.
2. Natural light from the sun or artificial sources; they produce high amount of UV radiation that degrade intrinsic properties of polycarbonate sheet.

It is a reason for the yellowish color that is common in most LED headlamps in vehicles. This is due to substandard anti-UV treatment.

“It is for this reason that all our polycarbonate sheet for any LED lighting portfolio has to be UV stabilized for optimal performance and reliability,” said Taylors Lei, WeeTect product manager.

WeeTect’s UV resistant polycarbonate sheets have co-extruded UV protective layer on both sides. The main aim is to prevent about 99% of any damage due to UV radiations. Combining this feature with light weight, enhanced light transmission, impact and chemical resistance, make this polycarbonate sheet a perfect choice for some LED lenses and lighting fixture applications.

This is the main reason why this UV resistant PC sheet is highly recommended for high-end engineering application and fabrication of SSL design in the lighting industry. Approving this polycarbonate sheet makes WeeTect a premier manufacture in China that produces a wide range of LED lighting equipment. This is for both the American and European standards.

With LED lenses and fixtures becoming more popular, WeeTect plans to launch more polycarbonate sheet products. The R&D is in the process of introducing a single product that will feature anti-fog, abrasion and UV resistance with an aim of making LED lenses and fixtures affordable to everyone. This will cut on the production costs.
