30W 3570 Dual-Color Temperature SMD LED: Tunable White for Modern Automotive Headlights
Headlights are no longer just "on" or "off". Today's cars switch between a crisp cool white for clear nights and a warmer, easier-on-the-eye warm white in rain, fog or city traffic. The 30W 3570 Dual-Color Temperature SMD LED makes that possible from a single 3.5 × 7.0 × 0.8 mm chip: two white dies spanning 2700–20000K, delivering up to 1300–1500 lm with a 120° beam. One component, two colour temperatures, one clever design.
Why a Dual-CCT 3570 Chip Wins on the Road
Automotive lighting is unforgiving: high flux, tight colour control, long life and brutal temperature swings. The 3570 answers with 99.99% gold-wire bonding, San'an / Epistar chips, efficient heat dissipation and a rated 50,000-hour lifetime across −40 to +85 °C. Because both white channels sit in one package, headlamp designers get tunable colour temperature without adding board space or extra optics.
6 Application Scenarios Where the 3570 Dual-CCT LED Pays Off
- Automotive headlights — low and high beam modules that switch colour temperature with the conditions.
- Daytime running lights (DRL) & position lamps — crisp, efficient markers with a long service life.
- Fog lamps & auxiliary driving lights — warm-white output that cuts glare in poor weather.
- Adaptive & matrix-beam headlamp modules — tunable white for intelligent, on-demand light shaping.
- Aftermarket & motorcycle headlights — retrofit projector lenses and LED upgrades that run cool and bright.
- Off-road & work lights — rugged auxiliary lamps for trucks, ATVs and heavy equipment.
