Company has 34 grants secured to date, with six patents covering solid-state light switch and dimmer switch architectures, as well as LED drivers

DUBLIN, CALIFORNIA (September 29, 2022) – Amber Semiconductor, Inc. (AmberSemi™), a leading technology developer of patented, innovative technologies for AC Direct digital management of electricity in silicon chip architecture, today announced that its pool of 34 secured patents includes significant grants around next generation, semiconductor-based lighting technologies. 

 “Our patent protection in the lighting area is of strategic value to AmberSemi, given how disruptive our technologies are to this sector, and how pervasive the lighting category is across the world,” said Thar Casey, CEO at Amber Semiconductor, Inc. “The expansion of our secured patent pool to 34 is a testament to the strength and disruptive nature of its technologies. It also points to the value AmberSemi is building as a company in its mission to upgrade the outdated, in cumbent old tech-based building electrical endpoints to modern semiconductor architecture in every electrical product in every building on earth.”

Amber’s breakthroughs are anchored in three patented core technologies and 10 patent grants for:

  • AC Direct Control and Protection: Solid-state based electricity control, switching thousands of times faster than conventional electrotechnical based switching with both self and downstream transient protection capabilities in solid state.
  • AC Direct DC Power Delivery: DC power extraction directly from the AC Mains in a much smaller silicon chip form factor than today’s electromechanical power supplies.
  • AC Direct Sensing: Realtime, continuous high resolution current sensing of the AC Mains – for monitoring and identification of typical and atypical states.

Amber’s lighting solutions leverage these patented core technologies, plus six additional lighting specific patents covering capabilities such areas a control of AC power for digitally controlled dimming and silicon chip-based smarter LED drivers. While the full portfolio of secured patent grants is important in general for the company in a range of use cases and product application categories, those in the lighting sector are specifically disruptive given Ambers advantages of digital control of electricity in silicon chip architecture. 

In a parallel news release from earlier today, AmberSemi announced the start of the siliconization process for its AC Direct 3-Wire Lighting Control Engine as a core power control and protection architecture for dimmer switches. The patented technologies are an excellent example of how AmberSemi’s breakthrough digital control of electricity in solid-state architecture solves major industry problems and delivers dramatic, next generation enhancements to a product category – in this case, dimmer switches. Key improvements for the dimmer switch category include:

  • Much smaller size: Smaller power architecture based on the small silicon chipset form factor.
  • More dynamic power delivery: Dynamic power provisioning, providing both housekeeping power for the dimmer itself and the capability to power other functions like sensors, wireless control and more with no change in size form factor.
  • Universal load compatibility: The architecture incudes embedded intelligence powering universal load compatibility in dimmers (incandescent, halogen, CFL, LED, ELV and MLV loads) via forward and reverse phase control. Another significant advantage is opportunity for manufacturers to reduce sku counts and improve the economics of their dimmer product lines.

AmberSemi’s pool of secured patents has now grown to 34, with more in review by the USPTO, as well as global review boards; and new filings are being submitted every quarter. The company’s breakthrough digital control of electricity in semiconductor architecture is so disruptive and transformative to the legacy old tech standard architectures today that IP protection is a central part of the company’s strategy. Its patent portfolio covers its core technologies, and product applications aspects in lighting, circuit breakers, transient detection, networked energy management, outlets, smart multi-function receptacles and more. In addition, the company’s patents include the byproduct of a building electrical grid powered by AmberSemi intelligence for unique whole building energy and environmental data analytics, essential patents around smart building control and awareness.
