A residential lighting brand needed LED chips for a new line of smart ceiling lights. The fixtures required high CRI (Ra90+), flicker-free dimming (0.1-100%), and color tunability (2,700K-6,500K) for home automation integration. Existing LEDs suffered from visible flicker on camera and poor dimming performance below 5%.

Queendom Solution

Queendom provided SMD 2835-HC high-CRI chips with Ra90 min, 200+ lm/W efficacy, and flicker-free 0.1% dimming via constant-current driver. The chips achieved <1% flicker index at 100Hz PWM, compatible with major smart home platforms (Alexa, Google Home, Apple HomeKit).

Key Advantages:

  • SMD 2835-HC: Ra90 min, 200+ lm/W
  • Flicker-free: <1% flicker index at 100Hz PWM
  • Dimming: 0.1-100% constant-current
  • Tunable CCT: 2,700K-6,500K (warm to cool white)
  • Smart home: Alexa, Google Home, Apple HomeKit compatible
