There are not many low-power manufacturers in China, such as Corey Chip 2835. The main reason is that we can't get the genuine CREE chip. Secondly, there is no patent authorization from Cree.
Everyone knows that many export markets have patent technical barriers, especially Japan. Without patents, it is basically hopeless to enter this market. With the patent authorization of Kerui, it is basically no problem to export to any corner of the world.
The parameters of 2835 depend on the chip size and the packaging technology used. At present, Planck's white light display finger can reach more than 95, and the lamp bead of 0.2W CREE chip can reach 24-26LM.
