Launch of the latest semiconductor chip to realize the promotion of the LED lighting industry

New integrated controller HVLED805, while lowering component costs and complexity
Optimization of LED lamp light output and lifespan

– STMicroelectronics ( www.st.com ), a world-leading integrated semiconductor company and global leader in power technology, has launched the latest semiconductor chip for high-efficiency LED (Light-Emitting Diode) lamps.

Government agencies and international organizations, such as the U.S. Environmental Protection Agency (EPA) and the European Commission (EC), are supporting LED lighting as an eco-friendly alternative to inefficient incandescent bulbs to help meet global greenhouse gas reduction targets. Furthermore, many countries around the world have already announced measures to phase out commonly used incandescent bulbs within the next few years.

By switching incandescent lighting, which accounts for up to one-fifth of national electricity consumption, to CFL (compact-fluorescent) or LED retrofit bulbs, CO2 emissions in Europe can be reduced by up to 15 million tons, and energy demand for 11 million households can be reduced. According to EU estimates, assuming about 20 light bulbs are used in a household, up to 50 euros can be saved per household annually. In addition, according to the EPA, LED bulbs certified under the ENERGY STAR® program use at least 75% less energy than incandescent bulbs and last for at least 15 times longer, as well as offering advantages such as significantly lower heat dissipation and precise light distribution.

Compared to alternatives to incandescent lighting, modern LED lamps using industry-standard components are expected to secure up to 80% of the global market share by 2020 due to rapid performance improvements, even though they offer lower total light output than CFLs of similar performance. Furthermore, LEDs offer key advantages to consumers: unlike CFLs, LEDs do not contain mercury, have a longer lifespan, generate similar levels of light output per watt, and provide instant light without any setup time.
