High brightness applications drive high power LED shipments

2014 to 2017, the compound annual growth for high power LED street lamp, direct type backlight, lighting and other high brightness application equipment shipments rate (CAGR) is expected to reach 13%. NPD DisplaySearch LED lighting and display quarterly report on supply and demand Quarterly LED Lighting Display Supply/Demand Report predicted that the demand for high power LED will increase from 18 billion 500 million in 2014 to the 27 billion in 2017 in. 2014, the application of high power LED in street lamps will account for 28% of the total shipments of high power LED, followed by TV backlighting and spotlights, each accounting for 27%. However, NPD DisplaySearch predicts that by 2017, street lamps will dominate the high power LED market, with a share of 41%, followed by spotlights (21%) and TV backlighting (15%). NPD DisplaySearch LED analyst She Qingwei said: "although the price is higher than the small and medium-sized high power LED power LED, but in the street the cost structure of LED light source, only a small part of the total cost of the lamp, street lamp in order to reach the required high reliability and performance, most of the factory will taking use of high power LED reliability the degree of better, thus promote the growth in shipments of high power LED. And with the rising cost of energy, governments in order to achieve the purpose of efficient energy saving, high brightness lighting demand will continue to grow." High power LED shipments to the lighting equipment (unit: million tablets) source: NPD DisplaySearch LED lighting and display Quarterly LED Lighting and and quarterly report on Display Supply/Demand Report to improve thermal conductivity, high power LED ceramic substrate instead of the original the use of PPA materials. At the same time in order to avoid the influence of humidity on the LED, the use of glass instead of silicone packaging. She Qingwei said: "in the use of high power LED, the heat management is very important, because the impact of product reliability." Qingwei she added: "high power LED with good sales, and we predict it in general lighting and direct type backlight penetration will be increased this year. However, this market will continue to be dominated by several major LED manufacturers, including PHILPS Lumileds (Philips Lumileds), OSRAM (OSRAM) and CREE (Cree)."
