The Five Numbers That Decide a LED عالي الطاقة Design
A high-power datasheet carries dozens of parameters, but five of them determine whether your luminaire hits its photometric target at 50,000 hours. Read them in this order:
- Thermal resistance, junction-to-case (Rθ J-C) — typically 4–8 °C/W for 1–3 W packages. This number, multiplied by dissipated power, tells you the temperature rise the heatsink must absorb.
- Maximum junction temperature — 110–125 °C rated, but design to hold Tj at or below 85 °C for the L90 life target; every 10 °C reduction roughly doubles time-to-70%-output.
- Flux bin at the stated test current — luminous flux is always binned (e.g., 100–110 lm at 350 mA). Design to the bin floor, never the typical value.
- Forward voltage range — the min/max window at test current, typically 2.8–3.6 V. Driver selection and series-string arithmetic use the max for current headroom and the min for open-circuit protection.
- Test current versus rated maximum — a part tested at 350 mA but rated to 1 A is telling you the photometric tables are not the ceiling; derate to 70–80% of maximum for long-life products.
Thermal Design Quick Reference
| Path Element | Typical Value | Design Note |
|---|---|---|
| Junction-to-case | 4–8 °C/W | Fixed by the package; compare across vendors at equal die size |
| MCPCB, thermal pad to plate | 1–2 °C/W | Use 2–3 oz copper and filled vias under the pad |
| Tim / gap pad | 0.5–2 °C/W | Thermal grease outperforms pads but complicates field service |
| Heatsink to ambient | Project-specific | Natural convection needs roughly 50–80 cm² of fin area per watt dissipated |
From Datasheet to Luminaire
Two of our deployment write-ups trace this exact chain: the municipal solar street light case shows bin-floor budgeting against battery constraints, and the UFO high-bay factory case documents a 5 W-class multi-die design held at L90 over 50,000 hours. For component-level reliability methodology, see the LM-80 lifetime estimation guide.
Frequently Asked Questions
Can I parallel two high-power dies on one driver?
Not directly. Forward-voltage mismatch makes current hog one die. Use separate constant-current channels, or a purpose-built multi-die package where the manufacturer has matched the dies internally.
What surge rating should the driver carry for street applications?
10 kV common-mode / 6 kV differential (IEC 61000-4-5) for pole-mounted luminaires on buried distribution, with line-to-neutral MOVs on the AC side of the driver.
How do I convert luminous flux to illuminance at the ground?
Illuminance (lux) = luminous flux (lm) × utilization factor ÷ area (m²). Outdoor pole installations typically realize a 0.35–0.55 utilization factor after optics, dirt depreciation (0.9), and lumen maintenance (0.9 at L90) are applied.
