There are two sides to talk about Ultraviolet LED sterilization:
First, ultraviolet irradiation all kinds of bacteria, such as DNA, RNA, etc., to interrupt or rearrangement, destroy bacteria, viruses, DNA, This makes bacteria can not be divided into replication, play a role in disinfection. Thereby enabling the bacteria died of natural causes or kill bacteria;
Second, the role of ultraviolet radiation on the oxygen in the air to produce ozone oxidation,oxidizing ozone can kill bacteria.. Basically all bacteria can kill, even for large creatures also have an impact.Such a conclusion that uv led strip has already been used for water and air disinfection, UV led lamps produce ultraviolet C (UVC) irradiation of the water,the water of bacteria, viruses, algae to have accepted such a UV lighting(such as UVC  wavelength 254nm irradiation). the cell’s DNA, RNA structure was destroyed, the cell can not be regenerated, bacterial virus loss of self replication, so as to achieve the purpose of disinfection.

UV LED working conditions in indoor
Ultraviolet light strip for indoor air disinfection,often can not be reached on schedule sterilization effect because of irradiation intensity is not enough,   so we need to detect the radiation intensity of ultraviolet light,The UV led basic idea was this use of UVC radiation intensity ultraviolet germicidal wavelength to irradiate,  therefore detect radiation intensity UV led with UVC ultraviolet radiation meter (also called UV light meter, UV intensity meter, etc.).  UV radiation intensity is the basic factors for affecting the disinfecting effect, according to the “disinfection technical specifications” provisions. ordinary 30W UV lamp, the new UV lamp radiation intensity should be greater than 100VW / cm2 (distance 1m) is qualified, the radiation intensity of the lamp is used to reach the minimum 70VW/cm2 can be used, but must be increased irradiation time.
According to the formula of ultraviolet irradiation = ultraviolet radiation * irradiation time can be obtained to extend time for different intensity, it can also be obtain that low-intensity or high-intensity short time sterilization can get the same effect. If the intensity of the ultraviolet light source is less than 40VW / cm2, it can not be used to prolong the irradiation time. Do not think that as long as the UV lamp is lit,The UV led Will be able to job( sterilization).

uv led strip Divided into UVA,UVB, UVC& UVD.What’s the difference between UVA,UVB, UVC& UVD band.

*UVA band, the wavelength of 320 ~ 400nm, also known as UVA rays. It has a strong penetration, can penetrate the most transparent glass and plastic. Ultraviolet sunlight contains more than 98% can penetrate the ozone layer and the clouds to reach the earth’s surface, UVA can the skin dermis,ultraviolet light can produce UVA.300-420nm wavelength can be completely through the special glass tube by coloring the visible light, near ultraviolet radiation only with 365nm as the center, can be used for the identification of ore, stage decoration, lighting and other places.

*UVB band, wavelength as 275 ~ 320nm, also known as medium wave erythema effect. ultraviolet middle-penetration, the shorter wavelength is absorbed by the transparent glass portion, contained UVB sunlight is absorbed by the ozone layer most, only less than 2 percent to reach the Earth’s surface, in the summer, or the afternoon will be particularly strong ultraviolet radiation on the human body with erythema .UVB effect, The UVB can promotes positive blood flow and Forming mineral metabolism & vitamin D in the body, but the long-term or excessive radiation can make the skin tan, and cause redness peeling ultraviolet lamp health, plant growth lamps emit is to use a special transparent purple glass.

*UVC band, wavelength as 200 ~ 275nm,  also known as short-wave UV sterilization. It has the weakest penetration ability, can not penetrate most of the transparent glass and plastic.The sun contains the short wave ultraviolet radiation almost completely absorbed by the ozone layer., the wavelength of 100 ~ 200nm, also known as the vacuum ultraviolet. long-term or high-intensity illumination can also cause skin cancer. UV germicidal UVC light is emitted UVC.

*UVD band, wavelength 100 ~ 200nm, also known as vacuum ultraviolet rays.

The disinfection principle of uv led strip is to destroy and change the structure of DNA (DNA) by ultraviolet irradiation,
the bacteria can not reproduce or death immediately, to achieve sterilization purposes.
Ultraviolet sterilization is a pure physical disinfection , with simple and convenient, broad spectrum, no secondary pollution, ease of management and automation, etc., With the introduction of various new types of ultraviolet light strip, the application scope of ultraviolet sterilization is also expanding.

4 in 1 RGBW led strip with well-deserved mainstream.. The reason is that the LED color easily, energy saving, long service life. the price is very expensive on A few years,the cause has been unable to spread. Generally falls within the acceptable range of users. So we preferred LED lights, then you know it better?   www.ledlightmake.com summarize some LED lights strip with knowledge, as a reference when you choose!

LED overview
led lights with LED assembly refers to the strip of FPC (flexible PCB printed circuit) or PCB assembly, due to the product shape, like a band named. Because of the use of long life (normal life in the 8-10 million hours), green environmental protection and gradually emerge in a variety of decorative industries.

Classification
LED lights with conventional and LED light bar is divided into two flexible LED lights,

Difference
* flexible LED lamp with FPC as the assembly line PCB board, the assembly with the chip LED, so that the thickness of the product is only a coin thickness, does not occupy space;
*The advantages of the hard light is easy to fix relatively, processing and installation are more convenient; the disadvantage is not random bending, not suitable for irregular places.

1 four-line LED lights with four wires, , three rows of Lamp beads (note is not the four row of Lamp beads Oh ~ ~) per row 24 Lamp beads in 1 meters,, 24*3=72.Because the power of each light bead is 0.05W, power LED lights with 72 beads is: 72*0.05=3.6W.

2 Four line LED pcb board width approximately 22mm,The thickness as 8mm, about 0.25kg/m

3  each 4 in 1 RGB LED strip with necessary with a special plug (plug with transformer); inevitable to remove the transparent plastic cover when convergence,, don’t be connect the test lamp after the cover directly.as promised easily short-circuited!

4 per meter have “scissors” signs, only in the logo was cut, only in the flag was cut, cut, or cut partial will lead to the wrong one meter does not shine! preferably before cutting a careful look at the sign position, Careful look can see.

5. Installation of LED strip, ordinary lights on the slot, straight as you can, also can be fixed with a cord or wire. if user need that exterior or vertical installation,
purchase of the other air plug and the end of the plug Is necessary. The original clip is transparent wholly, How about some glass cement when installation is finish. such as 910 is better.

Why, elaborately decorated with led strip

With the improvement of living standards, people’s also may be altering pursuit of material that the pursuit from the luxury previous change to comfort and environmental protection. Led strip into people’s live with color fidelity, diversity, environmental protection, long service time  characteristics.Now home decoration, in addition to pay attention to the cultural connotation, we should also pay attention to light, color mix and energy saving, environmental protection requirements,  LED lights are just meet these condition.

LED lamp strip (4 in 1 RGBW led strip) are common, bright, ultra-bright, to meet the needs of different user; luminous colors are red, green, blue, yellow, green, purple, colorful, white, suitable for different environments,the requirements of different occasions; low power:
a single led only 0.06W and 0.03W voltage by DC 12V power supply, safe, environmental protection (DC no stroboscopic, can protect your eyes). In addition, The LED light bar is soft, can be bent shape, suitable for different places of decorative needs;
coupled with input voltage  the led strip possess volume of small, light, thin, install place is small, also to meet people’s pursuit of space.

Infrared signal on ir led strip

Currently, there are two types of integrated receiver to Handle Signal of ir led strip: level type and pulse type, commonly used type which are pulse type, pulse type’s rarely used. Level type: receive 38K signal continuous, user can output low level continuous, time can be unlimited. Its internal amplification and pulse shaping is coupled directly, so that it can receive and output continuous signal. Pulse type, can only receive intermittent 38K signal, if the receiving 38K signal continuous, will remain high after several hundred MS, unless the distance is very close (within twenty or thirty cm).

Its internal amplification and pulse shape is a capacitive coupling, so it can not be able to receive and output signal continuous. In General the remote control adopt pulse type, only in the special occasions, such as serial modulation output, because the serial port may be continuous output data 0, so adopt the level type.General remote controller will be output 37917HZ after12 frequency division  with 455K, referred to as 38K, 10 m receiving bandwidth is 38±2K, 3 m 35~42K.in the deserted space ,the direction will be more strong when distance in 10 meters above. In the interior, if the wall is white, there is no direction in the space of 15 meters. The receiving head must have the filter, and the white light is filtered out. It will affect the receiving environment under the following conditions, or even more severe:

1, in a glaring blaze that made photosensitive tube saturation. infrared components are also very strong in white light.
2, a strong infrared heat source.
3, a stroboscopic light source, such as fluorescent lamps.
4, strong electromagnetic interference, such as daylight lamp start, motor start, etc..
38K signal is best to use 1/3 duty cycle, this is the most commonly used, it is better to test the 1/10 duty cycle. Actual modulation time should be less than 50%. Best to have intermittent.
