The U.S. Department of Energy has just published the latest edition of its biannual report,Energy Savings Forecast of Solid-State Lighting in General Illumination Applications, which models the adoption of LEDs in the U.S. general-lighting market, along with associated energy savings, based on the full potential DOE has determined to be technically feasible over time. The new report uses an updated 2016 U.S. lighting-market model and extends the forecast period to 2035 from the 2030 limit that was used in previous editions.
“Promising” and “remarkable” are two words U.S. Department of Energy’s Ames Laboratory scientist Javier Vela uses to describe recent research results on organolead mixed-halide perovskites. Perovskites are optically active, semiconducting compounds that are known to display intriguing electronic, light-emitting and chemical properties. Over the last few years, lead-halide perovskites have become one of the most promising semiconductors for solar cells due to their low cost, easier processability and high power conversion efficiencies. Photovoltaics made of these materials now reach power conversion efficiencies of more than 20%.
The last phase of China’s incandescent bulb ban will be effective as of Sept. 30, 2016. China will ban the imports and sales of 15W and above general incandescent bulbs Starting from Oct. 1, 2016, and will make adjustments based on interim evaluation results, reported Yicai Global.
The latest report from LEDinside, a division of TrendForce, finds that the global average price of 40W-equivalent (equiv.) LED light bulbs arrived at US$10.2 in February, down 0.6% from the prior month. The global average price of 60W-equiv. LED light bulbs also fell 0.5% monthly to US$14 in February.
