Energy Focus Awarded Patent for RedCap® Emergency Battery Backup LED Lamp

May 7, 2019

SOLON, Ohio, May 07, 2019 (GLOBE NEWSWIRE) -- Energy Focus, Inc. (NASDAQ:EFOI), a leader in LED lighting technologies, has been awarded US Patent 10,236,716 for the RedCap® lamp (“RedCap®”), Energy Focus’ breakthrough emergency battery backup LED tube technology.

The patent for the RedCap®, which is UL-approved and DLC-certified, describes Energy Focus’ proprietary concept and design of an integrated, general purpose LED lamp and emergency backup battery. One side of the lamp is connected to switchable AC mains to power the lamp for normal illumination, while the opposite end of the LED lamp is connected to an emergency mains circuit. In a power outage, a microprocessor in the lamp immediately detects the power loss and initiates the battery power for emergency egress illumination. The RedCap® therefore functions as a normal, efficient LED lamp when building power is on, and becomes and stays lit during power outage as the battery inside automatically powers the lamp.

“We’re extremely proud of our cross-functional teams that ideated and developed such an impactful and disruptive product as the RedCap® from scratch, based on our deep understanding of customer pain points,” said James Tu, Chairman, CEO, and President of Energy Focus. “By eliminating the need for the installation of a separate, external emergency backup battery, RedCap® significantly reduces overall retrofit project cost and time and in the meantime enhances the sustainability profile of the buildings due to less materials required. We’re pleased that the US Patent office has also recognized the breakthrough achievement for the technology of RedCap®, which represents a triumph of innovation by combining technical ingenuity and customer problem-solving.”

“Shrinking the size of the emergency battery pack to the point where it became possible to incorporate it inside a long life LED tube - while still meeting or exceeding emergency lighting requirements - was the problem our technical team solved,” said John Davenport, Chief Scientist at Energy Focus. “The solution, as outlined in the patent, involves both a unique circuit and program that dynamically monitors and controls the operation of our highly efficient LEDs along with the charge and discharge of the batteries.”

“According to various industry and company estimates, there are approximately 1.8 billion fluorescent sockets in the U.S. to be retrofitted to LED in the non-residential market, which would require one emergency backup battery for, on average, every ten to twenty fluorescent lamps for commercial and public buildings to comply with the emergency lighting codes,” said Mr. Tu. “We believe that the emergency backup battery market that RedCap® uniquely addresses is in the billions of dollars in the U.S. alone and several times of that globally. With our renewed customer-centric mission and distribution strategy, we believe that RedCap®, now patent protected, will not only establish a more financially and environmentally sound LED retrofit mechanism for the lighting industry, but also propel our growth ahead.”
