LED Lighting Overview: Market Considerations Major Markets
Entertainment / Theatrical Architectural Lighting Retail / Office Lighting Signage Street Lighting
Applications RGB
– Early growth in entertainment space– Quick adoption into architectural lighting
White– Vast adoption following the growth in LED technology– Energy efficiency initiatives speeding up market penetration

LED Design Challenges: Binning LED Manufacturing companies sort their product by “Bins”
based on lumen output, chromaticity, and wavelength
Leads to complications in the board-level manufacturing process
Many ways to compensate: SMT Line part placement Calibration in software Closed loop feedback

Binning Compensation
SMT line placement: Treat different bins of LEDs as different components and place
accordingly
Calibration Techniques: Current Control
– Use 1 bin per board– Constant current control
Power Control– Forward voltage implications over time and temperature– Adjust current real time to compensate for variation in forward
voltage

Binning Compensation (Cont’d)
Feedback techniques: Light sensor:
– Sense light output and adjust power accordingly– Lifetime adjustment:
– Use light sensor to detect reduced light output due to degradation of efficiency over long periods of time
– Adjust power to achieve previous light output, extending the lifetime of the product
Lifetime considerations: Thermal Management Current and temperature relationship used to estimate lifetime Measured by “L70” for white and “L50” for RGB

PCB Design Considerations
LED lighting fixtures are usually serial in nature Power is usually passed along the “daisy chain” along w/ data Leads to increased difficulty in board-level designs to minimize
losses When designing for manufacturability, must provide for worst-
case scenario– e.g. A 4 fixture chain powered by 24V @ 1A– Power only comes into first board so it must carry current for
all other boards to the output connector– Size traces accordingly– Minimize distances between input and output
EMI Critical for offline applications LED fixtures held to same EMI standards as traditional lighting
sources Difficult to design for EMI with PWM implications

PCB Design Considerations (Cont’d)
Thermal issues: Transistors switching LEDs will generate heat LEDs themselves generate heat (~25% efficient)
Thermal solutions: Metal Core PCBs popular for heat dissipation Mechanical integration key for heat sinking / thermal flow Temperature monitoring via onboard thermistors
– Thermal shutdown or compensation– Active over LED lifetime
