High-Power Tunable White COB LED
High-power tunable white COB LED modules bring adjustable CCT to the fixtures that need it most: theatrical Fresnels, broadcast soft lights, film space lights and large architectural washes. TYANSHINE's TW platform family scales from compact 7W engines up to 700W-class professional modules — on one consistent packaging architecture.
The Power Ladder
| Class | Power range | Typical fixture |
|---|---|---|
| Compact | 7W–26W | Accent spots, small panels, retail track |
| Mid power | 30W–150W | Fresnels, studio soft lights, wash lights |
| High power | 150W–700W | Theatre Fresnels, space lights, large soft sources |
The standard published lineup covers the compact class (TX-1307SW through TX-H1825SW, LES Φ7.5–13.8mm); mid- and high-power TW platforms are configured per fixture project on the same die and phosphor architecture.
What Limits Power in a TW COB — and How We Handle It
- Heat density: two interleaved channel dies double the die count per area. Ceramic and superconductive substrates with eutectic-class bonding keep Rth low (down to 0.45 K/W) so Tj stays in the reliability window — see the thermal management guide.
- Channel balance at high current: warm and cool phosphors respond differently to current density. Platform-level calibration keeps Duv controlled across the drive range, not just at rated current.
- LES size vs optic: higher power wants a larger LES to hold surface brightness; the platform family offers multiple LES diameters so the reflector design survives the power upgrade.
CCT Windows for High-Power Engines
The same windows as the platform family are available at scale:
- 2700K–6000K / 2700K–7000K / 3000K–5500K (full-range lines)
- 1800K–4000K / 2700K–4000K / 3000K–4000K (warm-leaning lines)
With CRI options up to 95 (98-class on request) and MacAdam 3-step binning across channels — see the high-CRI configuration.
Fixture Integration Checklist
- Define target illuminance at throw distance → derive flux, not wattage (see the selection guide)
- Size the heatsink for real Tc at worst-case ambient, then confirm rated flux/lifetime at that Tc
- Choose CC or CV drive — for distributed high-power arrays, see the constant-voltage configuration
- Validate CCT stability over dimming from 100% to minimum intensity
