And no mercury — Minamata Convention ready
A UV-C LED with enough output to replace mercury lamps. A metal substrate instead of sapphire, a 2D p-electrode instead of a point contact — the two structural causes of high-power failure are gone.

01 — Performance
Single-chip output, measured
For UV-C LEDs, single-chip output is the one figure that decides whether a lamp can be replaced. Read it apart from multi-chip totals.
02 — Structure
What is different
HHP keeps the vertical structure's strengths — full emitting area and a metal substrate — and removes its one remaining weakness: the point-contact electrode. Three structural choices, one chip.
Textured n-GaN surface
The entire top surface emits. Micro-texturing scatters light out of the crystal instead of trapping it, so extraction efficiency rises without any added optics.
2D p-electrode
The electrode is formed as a plane on a highly doped layer, not a point. Current spreads evenly, crowding disappears, and forward voltage stays low — efficiency in lm/W holds at high drive current.
Plated-Cu substrate
Copper replaces sapphire under the junction. Thermal conductivity rises threefold, heat does not accumulate, and lifetime extends to 15,000 h.
| Lateral | Vertical | HHP | |
|---|---|---|---|
| Emitting area | ~80% | >90% | >90% |
| Heat dissipation | 1× | >3× | >3× |
| Current spreading | ★☆☆ | ★★☆ | ★★★ |
| High-current efficiency | Droops | Declines | Maintained |
03 — Regulation and market
Under the Minamata Convention, mercury lamps are being phased out.
The only replacement source is the UV-C LED. One question remains — is there enough output to replace a lamp. ZeraBio is currently the sole commercial supplier above 150 mW on a single chip.
