Street lighting applications will lead the high power LED Market

Review: market research firm NPD DisplaySearch estimates that 2014 to 2017, for the high power LED street lamp, direct type backlight, lighting and other high brightness application equipment shipments (CAGR) compound annual growth rate will reach 13%; quarterly LED lighting and display the supply and demand mechanism (Quarterly LED Lighting and Display Supply/Demand and Report) forecast, 27 billion high power LED demand from 2017 to 2014 18 billion 500 million.

In 2014, high power LED street light application in high power LED will occupy 28% of total shipments, followed by TV backlight and lighting, each accounted for 27%, but NPD DisplaySearch forecasts to 2017, will dominate the high-power LED street lamp market share of 41%, followed by spotlights (21%) and TV backlight (15%).

NPD DisplaySearch LED analyst She Qingwei said: "although the price is high power LED medium power LED price is high, but in the street the cost structure, LED light source in LED only in the total cost of street occupies a small part, in order to achieve the required lamp of high reliability and performance requirements, most manufacturers will use high power LED better reliability, thus promoting the high power LED shipments growth. And with the rising cost of energy, governments in order to achieve the purpose of energy saving, high brightness lighting demand will continue to grow. "

In order to improve the thermal conductivity, high power LED ceramic substrate instead of previously used PPA materials; and in order to avoid the effects of humidity on the LED, the package is replaced by silica gel glass. She Qingwei said: "in the use of high power LED, the heat management is very important, because the impact of product reliability. "

She Qingwei added: "high power LED has a good sales volume, and we predict that this year it will grow in the general lighting and direct backlight. However, this market will continue to be dominated by several major LED manufacturers. "
