42V/17W LED Panel

Description

This LED panel was design as part of integrated lighting fixture in ceiling fan product.

The requirement was to achieve CEC Title 24-JA8 which limited the LED selection to 90+ CRI parts. Due to 90+ CRI LEDs having poorer lm/W than lower CRI parts, Samsung LM301B was chosen with it having best luminous efficacy at the time of design. Similarly to LED Panel Design 1, high LED count was required for even light spread due to limitation of distance diffuser.

  • LED Configuration: 14-series 6-parallel, total 84 LEDs
  • LED Specifications: Samsung LM301B, size 3030, 4000K CCT, Φv=30~34 lm, 90+ CRI, IF(max)=200 mA
  • Driven Current (module): 390mA (65mA per LED string)
  • Driven Voltage (module): 42V (14pcs LEDs @VF=3V)
  • Module Power: 17W
  • PCB: 1.6mm Metal-core, Ø 124mm, 1W/mK, white Solder-mask
  • Final Product Successful Certification: Energy Star, CEC Title 24-JA8
