Philips SON-T 17W and 26W LED bulbs use a built-in driver based on the Gan system, no external power supply required

Ottawa, ON / ACCESSWIRE / October 28, 2021 / GaN Systems, a global leader in GaN power semiconductors, today announced that Philips SON-T tubular 17W and 26W LED bulbs use GaN Systems power transistors. These products have groundbreaking designs, introducing innovative GaN-based drivers into LED bulbs, solving the technical problems of applying traditional glass products in high-power LED bulb applications. The result is a lower cost, higher power and more energy-efficient LED lighting solution.

Philips' high-power LED bulbs use GaN system-based drivers to provide lower-cost and more energy-efficient lighting solutions.

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

The combination of GaN's characteristics (such as high switching frequency) with GaN Systems' advanced technology and packaging allows Signify to implement this design beyond 8-10W bulbs without worrying about size and performance trade-offs. GaN-based drives provide:

High power density: Higher AC/DC circuit operating frequency (200-900 kHz) increases the power density of the LED driver.

High efficiency: This higher switching driver is more efficient than standard power supplies. The LED bulb has a constant efficiency of up to 96% at high temperatures, which is more environmentally friendly and has higher luminous efficiency.

Compact design: The built-in power supply has a diameter of 20 mm and a height of 15 mm. No external power supply is required, and installation and replacement are easier than ever.

Save space and cost: GaN can significantly reduce size and weight, and allows the use of smaller or fewer external components, thereby helping to save costs.

Longer product life: LED bulbs with built-in PSU can provide a higher level of dust and water protection, thereby extending product life.

These new Philips SON-T LED bulbs replace Signify’s traditional high-pressure sodium bulbs. They are ideal for road and residential lighting, decorative flood lighting, indoor and outdoor recreational sports facilities, and other commercial and industrial applications.

Jim Witham, CEO of GaN Systems, said: “GaN Systems is proud to be part of Signify’s LED driver breakthrough.” This marks the continued preference for GaN in more markets and the ability of GaN to increase performance to many levels before. Unachievable level in the application. "
