Concentration2024
The part that actually makes light inside an LED — the tiny gallium-nitride semiconductor die that converts electricity into photons — is overwhelmingly made in China, and San'an is the world's largest producer of it. So the global switch to LED lighting, and to LED and mini-LED backlights in TVs, monitors, phones and tablets, rests heavily on Chinese LED-chip capacity, with San'an the anchor. LED bulbs and screens are assembled all over the world, but the semiconductor doing the lighting comes disproportionately from a few Chinese epitaxy fabs. It's a concentration most people miss because the "Made in" label is on the bulb or the television, not on the chip inside — a textbook case of a downstream-assembled product hiding a heavily concentrated upstream component.

San'an isn't only LEDs. Through San'an IC it is building China's compound-semiconductor capability — gallium-nitride and silicon-carbide power devices (for EV chargers, fast chargers and power conversion) and gallium-arsenide RF chips (for 5G base stations and smartphones). These wide-bandgap and RF compound semiconductors are strategically contested, sitting at the heart of electrification and wireless, and are a focus of US-China technology controls. So the same company that makes the chip in your light bulb is also building the power and RF semiconductors behind EV charging and 5G — extending an LED giant into the geopolitically sensitive frontier of compound-semiconductor technology. The humble LED and the strategic power/RF chip share a gallium-based materials platform and, increasingly, a single Chinese maker — which is exactly why an LED company shows up in national-security technology discussions.
