The band and the dose
Which band a design uses, and what dose it must deliver, are stated in the design's own specification — target organism set, log credit and worst-case geometry — and confirmed per model in the enquiry exchange for the components it sources.
Nothing is dosed in
It is also why UVC disinfection works without dosing any chemical disinfectant into the water or air it treats — nothing is added, no disinfectant residual persists, and the treatment ends when the light switches off.
Why claims name their organism set
This is why disinfection claims must name their organism set and log target, and why "99.9%" without qualifiers is a non-statement. The company's published application cases — more than sixty of them — fall in three categories: water purification, air purification and surface disinfection.
The variables the designer actually controls
- Irradiance at the target — the irradiance figure recorded for the named model, under the conditions it was recorded under.
- Exposure time — flow rate through a reactor, or cycle design in a tank or cabinet.
- Wavelength — the band the design names.
- Geometry — whether every target volume or surface actually sees the light.
The limits, stated plainly
Shadowing: state the geometry the product can give the stage in the enquiry, alongside the dose terms. Turbidity and absorption: state the transmittance basis of the medium in the enquiry. UV transmittance is a design input, not a discovery to make after launch. No residual: no chemical disinfectant is dosed into the water or air it treats, and no disinfectant residual persists.
Enclosure, interlock and classification
State the enclosure and interlock arrangement your design provides in the enquiry, and name the finished product's photobiological safety classification among the validation items the equipment maker carries.
What this means when buying components
Specify the claim, not the adjective: target organisms, log credit, design dose, worst-case geometry. The same enquiry names the band (see the wavelength guide) and the form — chip, package or module — and ask which per-model ratings are documented for the model you are sourcing, to be confirmed in the enquiry exchange. State the exposure time and the geometry the product can give the stage alongside the dose terms, and ask which of those inputs the documentation for the named model is recorded against.
The catalogue behind the claim
The catalogue these claims are specified against lists chips across 255–340 nm, SMD packages in 3535 and 6868 formats, and disinfection modules for water, air and surface equipment. Behind the catalogue sits the chain the company publishes: its own GaN MOCVD equipment, epitaxial growth on sapphire, chip fabrication and packaging. Which band, form and ratings a design uses are established per model in the enquiry exchange. The company's module range covers water, air and surface disinfection, and its published application cases — more than sixty of them — sit in those same three settings.
The meaning of "inactivated"
Dose documentation names its organism, its log target and its test basis — the terms in which a disinfection claim is stated, and the terms an enquiry for components should state as well.
The inputs the configuration is quoted against
The design answers are stated in the enquiry: the medium and its transmittance basis, the enclosure geometry, and the interior materials the design uses — the inputs the module configuration is quoted against.
The application categories behind the claim
The disinfection modules in this catalogue serve the company's published application categories: water purification, air purification and surface disinfection.
The claim, stated in full
Name the organism set, the log target, the dose basis and the worst-case geometry, and ask what is recorded for the named model.
The catalogue behind the claim
The catalogue these terms are specified against lists chips across 255–340 nm, with the main production bands at 260–320 nm and more than 1,000 standard chip models; SMD packages in the 3535 and 6868 format families, with eight catalogued models; and disinfection modules for water, air and surface equipment, with six catalogued module products. Behind the catalogue sits the chain the company publishes: its own GaN MOCVD equipment, epitaxial growth on sapphire, chip fabrication and packaging. The company's published application cases cover water purification, air purification and surface disinfection. Which band, form and ratings a design uses are established per model in the enquiry exchange. Company-published figures describe a team of 300+ people. The chip catalogue names three VF-series models — VF-40v, VF-20W and VF-20r — and the published catalogue keywords separately name a water-tank sterilization module. The company's own record runs from its first GaN MOCVD system in 2002 through 3-wafer and 6-wafer generations in 2005 and 2007 — the 6-wafer system recorded as a national 863 programme project — to the UV LED production line it built on its own equipment in 2010.
The component record an enquiry builds
An enquiry for components names the target organism set and log credit, the design dose, the worst-case geometry and the duty the product will run. It asks which per-model ratings are documented for the model being sourced — band, output and drive figures, and the conditions they were recorded under — and it names any validation file the finished product will cite. Those inputs, stated in the first message, are what the confirmation answers against.
Reading a disinfection claim
State the four terms — organism set, log target, dose basis and test basis — in the enquiry, and ask which of them the documentation for the named model records. The same enquiry names the band and the form the claim rests on — bare chip, SMD package or finished module — together with the quantities and programme timing behind it, so that what is recorded for the named model is established against the design that will actually be built. Nothing in that exchange assumes a standard datasheet; the record asked for is the named model's own.
One discipline, every medium
The same four terms — organism set, log target, dose, geometry — are stated for water, for air and for surfaces alike, in the enquiry for each medium.
Stating the terms in the first message
An enquiry states the claim it rests on, with the terms behind it: the medium the product treats, the target organism set and log credit, the design dose and the worst-case geometry it is quoted against, the duty the product will run, and the form under consideration — bare chip, SMD package or assembled module. Against those inputs, ask which ratings are documented for the named model — band, output and drive figures, and the conditions they were recorded under — and name any validation file the finished product will cite.
