Growing LED Power Supply Market Provides Opportunities for Small and Large Manufacturers

The market for power supplies used for light-emitting diode (LED) lighting applications will expand to more than $9 billion by 2019, up from approximately $3 billion in 2013. Growth is being driven by the rapid transition from alternative technologies to LED lighting across many applications. The main driver for LED adoption is its superior efficiency, which results in energy cost savings.

LED lighting shipments are now dominated by low-power applications, with the residential sector estimated to account for 46 percent of all LED power supplies shipped in 2014. In higher-power applications, such as the factory and warehouse segment, LED lighting adoption is much lower; however, LED adoption in higher-power applications is growing rapidly, due to continuing innovations in LED technology.

LED power supplies typically have different voltage and current requirements than power supplies used in other applications; moreover, many opportunities exist for non-established power-supply manufacturers to occupy their own niche in the LED lighting market. Doing so allows them to compete successfully with larger power-supply manufacturers in other areas that are unable to bring many of their existing products to the market.

Some challenges remain for LED power supply manufacturers As with any emerging technology, there are some challenges to overcome for LED supply manufacturers, despite a host of opportunities. For instance, the LED luminaire market is still very fragmented: the leading supplier, Philips, accounted for nearly 9 percent of the total market in 2013. Philips, which is also the leading supplier of LED lamps, comprised 27 percent of the market in 2013.

Given the large number of LED luminaire suppliers, there is a great deal of fragmentation among the various products. Each supplier typically requires its own unique set of current and voltage profiles, which makes it harder for LED power-supply manufacturers to provide a standard product for a large number of companies or applications. In turn, LED power supply manufacturers find it more difficult to reduce manufacturing costs, through standardizing processes and sourcing similar product parts.
