LED lighting to boost power supply market to $10 billion
THE global market for power supplies used in LED lighting is forecast to reach a monumental $10 billion in 2016. IMS Research’s recent report “Opportunities for Power Components in LED Lighting,” reveals that rapid uptake of LED lighting, driven by legislation and rising costs of electricity will result in a potential global market of 4 billion power supply units by 2016.
Report co-author and senior market analyst, Ryan Sanderson, commented, “Demand for LED lighting solutions is increasing rapidly for all applications from low-power residential retrofit LED lamps and bulbs to high-power commercial and industrial LED luminaires for applications such as street lighting.”
The report also says that the traditional lamp and luminaire market is well established. Manufacturers are faced with new challenges when it comes to powering LED lamps and luminaires and often require significant power electronics expertise, opening up opportunities for power supply manufacturers.
The requirements to power new LED lighting products varies widely, depending on design factors including power rating, the number of LEDs or LED strings and the environment in which the solution will be placed. Sanderson added, ”These design requirements, coupled with the lack of clear standards for LED lighting means that LED lamp and luminaire manufacturers need considerable power electronics expertise, either via employing specialists or from a merchant power supply manufacturer.”
Competition in lighting, however, is already fierce and some of the largest manufacturers of LED lamps and luminaires are positioning themselves to cope with these challenges internally.
Report co-author and market analyst, Jonathon Eykyn, commented, “Some of the largest manufacturers of LED lamps and luminaires already have the capability to design and manufacture power circuitry in-house, either via subsidiaries or through the acquisition of power supply providers. Philips Advance is a prime example”.
Veeco systems big in Asia for gallium nitride on silicon epitaxy
TAIWAN headquartered Epistar will use the Turbodisc K465i GaN MOCVD reactor to grow LEDs. South Korea’s LG Siltron will use the same tool to grow LEDs as well as power devices.
M. J. Jou, President of Epistar, commented, “We are pleased to choose Veeco’s K465i as our GaN-on-Si development tool. We are excited about the potential of GaN-on-Si technology as we move to larger wafer sizes. We appreciate the strong support from Veeco, and look forward to this collaboration.”
WILLIAM J. MILLER, Veeco’s Executive Vice President, Process Equipment, commented, “We are very pleased that Epistar has chosen the K465i, which provides low cost-of-ownership and production worthiness, for its GaN-on-Si LED development. Large diameter Si wafers offer tremendous promise as a low
cost alternative to sapphire for volume production of lower cost LEDs.”
Epistar manufactures high brightness LEDs of compact size, low power consumption and long life. LG Siltron, a South Korean epi wafer manufacturer, also chose the TurboDisc K465i GaN MOCVD system for production of GaN-on-Silicon wafers for power electronics and LED devices.
As traditional silicon-based power transistors approach their limits, materials such as GaN are gaining popularity to speed energy conversion at lower costs. A wide range of industries, including many in the green-tech space such as wind, solar, smart grid, and hybrid electric vehicles, are driving demand for energy-efficient GaN-based power electronics. GaN-on- Silicon may also offer an alternative approach to LED manufacturing.
