Signify Revolutionizes Lighting with Built-In Driver for Higher Power LED Bulbs with GaN Systems

GaN Systems announces that the Philips SON-T tubular 17W and 26W LED bulbs feature GaN Systems power transistors.

These products feature a new design that introduces an innovative GaN-based driver built into the LED bulb, solving the technical problems of applying traditional glasswork in a high-power LED bulb application. The result is a lower cost, higher power, and more energy-efficient LED lighting solution.

Initially, Signify's built-in driver design was limited to its 8-10W full glass LED bulbs. To implement this design for higher watt LEDs, the company switched from silicon to GaN power semiconductors. This particular innovation centers around the GaN-based AC/DC PFC circuit built into the E27 screw in the bulb. The driver uses GaN Systems 650V transistors (GS-065-004-1-L and GS-065-011-1-L).

The attributes of GaN, such as high switching frequency, combined with GaN Systems' technology and packaging, allow Signify to implement this design beyond 8-10W bulbs without worrying about size and performance tradeoffs.
