General Lighting LEDs Solutions

General-purpose illumination applications, from residential bulbs to commercial downlights and panel lights, demand LEDs that combine high luminous efficacy (>200 lm/W), excellent color rendering (Ra≥80), and long operational life at competitive cost. Key challenges include achieving uniform light distribution, maintaining color consistency across production batches, and supporting dimming for energy management and user comfort.

Queendom Solution

Queendom provides General Lighting LED packages in SMD 2835, 3030, and 5050 configurations, optimized for bulbs, tubes, panels, and downlights. Our SMD-2835-Ra80 series achieves ≥200 lm/W efficacy with Ra80+ color rendering, supporting both constant-current and dimmable driver designs.

Key Advantages:

  • SMD 2835: 200+ lm/W efficacy, Ra80/Ra90/Ra95 options
  • CCT options: 2,700K / 3,000K / 4,000K / 5,000K / 6,500K
  • Dimmable: PWM (flicker-free) + TRIAC + 0-10V compatible
  • Color consistency: < 3 SDCM MacAdam ellipse
  • Cost-effective: High-volume SMT-compatible packaging
