These first half of the application for the LED filament lamp patent, do you know? (one)

Apologize statement:

On September 6th, Gaogong LED official WeChat released the "These six filament lamp related patents, do you know?" article, due to editorial operation problems, the article was mistakenly labeled as "original". This article is an original article of the public layout of the patent, and is now officially apologizing to the operator of the public.

Since last year, the market for LED filament lamps has been bullish. Since the beginning of this year, many lighting manufacturers have started fierce price competition in order to survive, which has led to the frequent occurrence of LED filament lamps of various specifications and prices in major markets.

"For such price competition, some patented LED manufacturers also hope to ensure the smooth supply chain by patent authorization." An industry insider said.

At present, the manufacturers with patents related to LED filament lamps on the market include Japanese oxtail (USHIO), Nichia, Jingyuan Optoelectronics (Taiwan) and domestic Ledison, as well as traditional lighting international manufacturers. Relevant part of the patents owned by various mergers and acquisitions.

In 2006, Jingyuan Optoelectronics obtained patents for LED filaments in the United States, Europe, the mainland, and Taiwan. In addition, the domestic Rui Disheng has also authorized the filament lamp patent to give Super Trend and K-Lite.

In the future, with the gradual increase in the demand for LED filament lamps, more and more channel illuminators and stores will begin to receive such requests from patented LED manufacturers, so it is expected that in the second half of this year, The 'patent war' on LED filament lamps will be fully staged.
