Given the prevalence of downlights in US homes, potential energy savings from high-performing, energy-efficient downlights would be significant. Lighting accounts for 15-20% of household electricity use. DOE estimates there are at least 500 million recessed downlights installed in US homes, and more than 20 million are sold each year. Both CFL and LED technology can decrease downlight wattage by 75% or more.
The high-temperature environment in recessed downlights has plagued attempts to use CFLs in this appplication, but more than a dozen reflector CFL products proven to perform well at elevated temperatures are now on the market Recent developments in LED technology and luminaire design also look very promising, in terms of light output .
Energy is becoming more and more important for everyone. How to get safe, environmentally friendly and sustainable energy is the key issue for 21st century. Solar is a renewable and affordable solution and it will be one of the best choices for people and governments to support sustainable development.
With strong technical capacity and rich experiences, we have established close cooperation relationships with a large number of overseas and domestic customers. Currently we mainly provide the products as below:thin film coating technology is a contactless method of applying thin film coating solutions to web materials by modifying the micro-environment, will be our companies only direction in 2010.
The importance of Transparent Conductive Films (TCF)
Increasingly more and more flexible devices are required, from flexible displays for e-readers, OLEDs and other types to flexible photovoltaics and beyond.
These devices require a conductor to close the layers of active materials, but that conductor needs to be transparent in applications such as displays and photovoltaics to allow light through.
Today, transparent conductive oxides are widely used for rigid devices but these will become more expensive due to rare materials used, and are inadequate for most flexible electronics applications where they can easily crack under little strain. Alternatives are sought.
The main materials available for this purpose are:
* Transparent conductive oxides (TCOs)
* Organic materials, such as the most common PEDOT:PSS
* Carbon nanotubes (CNT) and graphene
Each have trade-offs between conductivity, transmittance, and flexibility. Each can be patterned in different ways. While sputtering will remain an important and high-volume technology for coating of rigid substrates like glass, solution-based processes including printing and the use of organic and nanoparticle materials have already gained a lot of traction and are expected to dominate the market for the flexible applications within a few years.
Significant new developments are being made with both the materials used and how they can be deposited. This report addresses the performance of the different options and profiles organizations around the world that are developing better solutions.
