UVC LED tape features:
1. With wavelength 265nm-278nm , the UVC strip light can damage DNA, destroying harmful micro-organisms in other liquids, on surfaces, on food products and in 'air'. mainly for germicidal use.
2.PCB customized, can be rigid bar or flexible PCB.
3.Length can be made as your request.
4.Taiwan imported UVC LED chip, 10000 hours lifespan.
5.If you prefer LG chip, we can supply also. LG is a leader in UVC chip production.
6. UVC LED tape light beam angle 120 degree or 60 degree as request.
7.SMD3535 or SMD3939 both are for option
So how to choose the right UVC products for your sterilization application ? please check the five suggestions then you know what to do exactly.
a. How long is your disinfection time ?
– To sterilize the general bacterial propagule: the radiation dose should reach 10 000 μW.s/c㎡
-To sterilize bacterial spores: should reach 100 000 μW.s/c㎡
-To sterilize viruses: disinfection time between the bacterial reproductive body and the spore
-To sterilize fungal spores: higher than bacterial spores, sometimes it needs to be irradiated to 600 000 μW.s/c㎡ (generally pathogenic fungi have weaker resistance to ultraviolet light than bacterial spores)
-To sterilize unknown target microorganisms: not less than 100 000 μW.s/c㎡ (Source: "Disinfection Technical Specifications")
-To sterilize coliform bacteria: should reach 20 000 μW.s/c㎡
-To sterilize the spores of Bacillus subtilis var. black: should reach 100 000 μW.s/c㎡
For example our UVC strip 30leds/m with lens uvc led strip can reach 1000μW/c㎡, so needs 10 seconds to kill general bacterial , 20 seconds to kill coliform bacteria, 100 seconds to kill bacterial spores......
b.How long is your disinfection distance from the UVC source to the sterilization surface ?
UVC LED radiation now is not as strong as tradiational UV lamp, can be used for distance less than 50cm. If more than 50cm disinfection distance , the LED will be much more expensive..
c. UVC LED beam angle 60 degree VS 120 degree let us take 20mw per chip as a comparison:
60 degree 20mw chip reaches 190.99μW/cm2 while 120 degree 20mw chip only gets 21.22μW/cm2, what a huge gap!!
d.Your application is for air disinfection or surface disinfection or water disinfection ？These needs different solutions
e. Flexible UVC strip VS Rigid UVC LED module
The uvc flexible strip light has two advantages :
1. flexible so can be installed in corner
2. can be cut as each 3 leds such as 10cm or 5cm , places that needs different length
The rigid uvc led module bar light has one big advantage is that it has a lot better heat dissipation function which means the power consumption could be quite big that can reach 70μW/cm2 at 100cm distance while UVC flexible strip can normally reach less than 10μW/cm2 at 100cm distance.
However, the UVC rigid module can not be cut, cannot be bendable , it has fixed shape...
If you have not an exact answer feel free to contact us for a professional sterilization solution.
To know exact how long the disinfection time required we shall know the UVC radiation dose , so the question is :how to measure UVC radiation with UVC meter ? Please check below video provided by Suntech
Do you need certifcates such as CE, RoHS, FCC for EU or USA market ? Yes our company is EPA registered and have these certificates as well
Did you purchase fake uvc LED ever ? see our germicidal test report authorized by GuangDong Detection Center of Microbiology below:
Some flexible UVC strip light & rigid LED module we supply , surely could be customized as well.
Measure UVC irradiation in Suntech factory workshop before delivery:
We can supply customized UVC control system as well, see below video

Effects of UVC LED sterilization,
Regarding UVC LED chip:
Knowledge about UVC LED , the wavelength ranges from 200nm to 280nm
While UVB radiation is widely recognized for its harmful effects on human skin and links to skin cancer, each of the UV bands (UVA, UVB and UVC) create different risks for humans.
Different wavelength UVA VS UVB VS UVC
UVA: from 320nm to 400nm
UVB: from 290nm to 320nm
UVC: from 200nm to 280nm
UVA is harmful to skin, UVB is risk to skin cancer, UVC can cause serious to skin, but we can not be touched by natural ultraviolet light, only by artificial ultraviolet light please see picture below:
UVC radiation refers to wavelengths shorter than 280 nm. These wavelengths are entirely absorbed by our atmosphere and no natural UVC radiation reaches the surface of the earth.
These wavelengths are available to us through artificial sources, such as UVC LEDs or mercury lamps. The intensity from point sources like UVC LED falls off as 1 over distance squared, and once it gets past the scattering length, it falls off exponentially.
This means that:
1) the further away the UVC source from a human, the lesser dose he is exposed to, and
2) the absorption length of UVC radiation in human skin is extremely short so that almost no UVC radiation can reach the living cells in the skin; all the absorption occurs in the dead cell layers.
Acute (short-term) effects include redness or ulceration of the skin. At high levels of exposure, these burns can be serious. For chronic (long-term) exposures, there is also a cumulative risk, which depends on the amount of exposure during your lifetime. The long-term risk for large cumulative exposure includes premature aging of the skin and skin cancer.
UVC can damage the skin cell's DNA structure ,rendering them incapable of reproduction
With deep ultraviolet LED UVC technology development, now we have SMD3535 UVC LED chip that can supply this particular wavelength.
UVC LED Application such as water disinfection, air sterilizer , air purification， surface disinfection.
Mostly used for Active water or air, not static water or air.
