Common imported LED light source brands include Osram Osram and CREE Kerui, Taiwan, China brands include Epistar, and Chinese Mainland brands include San'an Optoelectronics. The light source largely determines the light color, lifespan, stable operation, and so on of the lamp, so the choice of light source is very important. The following is an analysis of the advantages and characteristics of LED bead brands:
1. Osram: a century old German brand with advanced and mature high-efficiency, energy-saving, and heat dissipation technologies. Its light source can operate stably in extreme environments;
2. CREE: A US brand with innovative material technology and over 1300 US patents. Its white LED light efficiency reaches 254lm/W (laboratory data), making it a global leader. High luminous efficiency and reliability, excellent thermal performance, minimal heat release, and long lifespan;
3. Epistar Wafer Optoelectronics: Taiwan, China brand, one of the few enterprises in the world that can mass produce blue light GaN epitaxial chips, has more than 300 MOCVD equipment, mature technology, large capacity, and channel advantages;
4. Sanan Optoelectronics: a Chinese brand occupying 30% of the global LED chip market, with internationally leading Mini/Micro LED technology, achieving small batch production of 16K Micro LED chips;
The development of Chinese chips is getting better and better, and the technology in related industries is also improving rapidly. I believe that soon, our LED will be on par with international brands.
