China Joins Ban on Incandescent Bulbs



The world’s most populous country, China, is joining the ban on incandescent light bulbs. The Chinese government has decided to gradually phase out the energy-hogging lighting over the next five years saving the country lots of energy and some pollution too. 

China will ban imports and sales of 100-watt and higher incandescent bulbs starting in October 2012.  Bans will be imposed on 60-watt and 15-watt bulbs later over the five-year period. China joins theUSand the 28 countries in the European Union among others in phasing out traditional incandescent light bulbs.

Chinais one of the largest users and producers of incandescent bulbs.  According to an AP report, 3.85 billion incandescent bulbs were produced in China with more than a billion sold domestically. China’s NDRC says that the move will save 48 billion kilowatt hours of power per year and reduce carbon dioxide emissions by 48 million tones annually once the bulbs are phased out.

About Beth

It seems like LEDs are in everything these days – backlighting everything from your mobile phone, Apple iPad and flat screen HDTV to traffic lights, light bulbs and even the kitchen sink. But, making LEDs is a complex process that begins with the creation of sapphire. Not the pretty blue gemstone, but large commercial crystals that can weigh as much as 400 lbs. Once these large sapphire crystals are grown into boules and cooled, they’re cut into cores, cut further into flat circular wafers, polished and then used to grow LEDs. About 85 percent of HB-LEDs (high brightness) are grown on sapphire. There’s not that much information out there about the process. This blog is meant to shed some light (excuse the pun) on sapphire, LEDs and the industry that is devoted to making our lives just a little brighter. In the months ahead, we’ll tackle some topics that will help you understand a little more about sapphire and LED industry. Here’s a sample of what we’ll cover in the coming months: • Growing sapphire • For a wafer, size matters • Quality - When sapphire wafers go bad • LED light bulbs • Market & myths • Interviews with industry shining stars • Reports from industry events • Current events in perspective Please join us each week to learn more about sapphire and the LED market. We look forward to seeing you.
