Shipment of high-power LEDs to various lighting equipment (unit: million)
In order to improve thermal conductivity, high power LEDs use ceramic substrates instead of the PPA materials originally used. At the same time, in order to avoid the influence of humidity on the LED, the silicone package was replaced by glass. Yan Qingwei said: In the use of high-power LEDs, the management of heat is very important, because it affects the reliability of the product. Yan Qingwei added: High-power LEDs have good sales, and we predict that this year's penetration in general lighting and direct-lit backlights will increase. However, this market will continue to be dominated by several major LED manufacturers, including Philips Lumileds (Philips Lumileds), OSRAM and Cree.
2014-2017, CAGR of high-power LED shipments for streetlights, direct-lit backlights, spotlights and other high-brightness applications is expected to reach 13.NPDDisplaySearchLED lighting and display supply and demand quarterly report QuarterlyLEDLightingandDisplaySupply /DemandReport predicts that demand for high-power LEDs will increase from 18.5 billion in 2014 to 27 billion in 2017. In 2014, the application of high-power LEDs in streetlights will account for 28% of total high-power LED shipments, followed by TV backlights and spotlights, each accounting for 27. However, NPDDisplaySearch predicts that by 2017, streetlights will dominate The high-power LED market has a market share of 41, followed by spotlights (21) and TV backlights (15). NPDDisplaySearchLED analyst Yan Qingwei said: Although the price of high-power LED is higher than that of small and medium-sized LEDs, in the cost structure of street lamps, LED light source only accounts for a small part of the total cost of street lamps. In order to meet the high reliability and performance requirements of street lamps, Most manufacturers will use high-power LEDs with better reliability, thus driving the growth of high-power LED shipments. And with the rising cost of energy, high-brightness lighting demand will continue to grow in order to achieve energy efficiency.
