The principle of ultraviolet sterilization

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.

*choose the time of anti-virus. Each microorganism has its specific ultraviolet radiation, death dose, the irradiation dose is the product of the intensity and irradiation time (irradiation intensity = amount of fungicide? Irradiation time / K = I? T), Please carefully choose the time according to their own use and purpose disinfection.

*General household sterilization recommended 5 minutes.
*The officers left the scene, half a minute started antivirus. Then avoid personnel to enter
to the scheduled time after the automatic voice prompts and stop anti-virus.

*The automatic voice prompts after a predetermined time and stop antivirus.

main products of Decoration----led strip

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.

5 methods for the installation of LED strip

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.

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.

Home decoration

What is different from the integrated led slot and the traditional lamp slot? Led slot is the core element of the ceiling. Through hidden lamps, make the diffuse light to create an Romantic environment. In the “see the light but not light,” of the space inside, rendering a unique lighting environment.
1 at present, most of the traditional lamp groove is made of gypsum and wood, the properties of the material Limits Production process a. Decorative surface is too simple. The traditional lamp slot gives a impression that much of the lap ir led strip only.
2. In recent years, there are some designers started to try to use new materials, such as the pinch plate and secondary top materials with do light tank, the style is various, it’s dominated by splicing Aluminous gusset plate . the shape of the material does not have integrity,aluminous gusset plate surface are mainlybased inks, lack of texture, The designers many are barely used.Later replaced the leather carved soft packing material, the surface texture is up, or because of the lack of integrity, also lack of texture. 3 now we research and development of integrated lamp slot, both to maintain the integrity of the ceiling, but also increased the texture of the decorative surface. The integration of artificial stone and light patterns in one, these are popular materials. Can be free to meet any style you want.

The ir led strip make 940nm and 850nm infrared can be seen with the eyes?

The ir led strip  make 940nm and 850nm infrared can be seen with the eyes?
The answer is Can not. First thing we know,in general said, infrared light is 850nm or 940nm,Don’t that prove that it can emission of light as 850nm.there is a range of light it emits, and the 850 is its peak,
The peaksays it  weak and strong of light.but the light intensity to arrive at 0 light band ,still have a range, if in the visible light band, the spectral intensity (example: spectral intensity: the spectrum intensity is too small:lead in plant mineral element concentration increased,until more than soil the concentration of mineral elements,caused the plants to Water lossContrary too much: the root of aerobic respiration is reduced, resulting in mineral absorption is reduced or anaerobic respiration. ) also did not drop to zero point, of course you will be able to see.but The wavelength of light the human eye can see the longest is 770nm, when the spectral range of the infrared light emitted by 770, you will be able to see it.

Parameter analysis of infrared led strip

Parameter analysis of infrared led strip

in generally the photoelectric parameters of Infrared led strip have the following categories: According to the peak wavelength (P): 870nm, 880nm, 850nm, 940nm, 980nm.

compare them with price as follow:850nm> 880nm> 940nm,

use most is 850nm ir led  strip and 940nm ir led  strip on the led market . because 850nm has high emission power and irradiation distance is far.

so is mainly used for infrared monitoring equipment; and 940nm is mainly used for infrared remote control ,Agriculture and Industry Application,
Peak wavelength: λp (lambda P unit: nm)

magnitude of the radiation power received by the IR unit area (cm2) of the sensor unit area. Angle of up and down or left and right sides of the clip called half-power angle

Infrared temperature measurement principle

Infrared temperature measurement principle
the infrared rays emitted By receiving objects (infrared radiation similar to the IR LED strip produced infrared), the thermal image is displayed on the screen, to accurately determine the surface temperature distribution,with accurate, real-time, fast and so on. Any movement of object due to its own molecules movement .forming a temperature field on the surface of the object, commonly known as “thermal imaging”. Infrared diagnosis technology is to measure the temperature and the distribution of the temperature field by absorbing the infrared radiation energy, so as to judge the heating conditions of the equipment.
At present, Infrared diagnosis technology adoption of already existing knowledge offer huge opportunities.
such as infrared thermometer, infrared thermal television, infrared thermal imaging system, and so on.. All objects emit infrared energy (body temperature (36~37 ℃) in the infrared wavelength radiation is 9~13чm。). the hot of object are increasing,the molecules become more active infrared energy,The optical equipment is located within the infrared thermometer,the infrared thermometer optical devices can be collected objects radiation of infrared energy and energy accumulation in the detector. Subsequently, the detector converts the energy. Electrical signal, which is amplified and displayed as a temperature reading. To get the temperature user want.

Infrared led heating

Infrared led heating
Infrared led Produce heating whether efficiently. Mainly depends on the absorption of the object. The absorption rate more than high , the better the effect of infrared radiation. The absorption rate depends on the type of heated material, the surface state, and the wave length of the infrared radiation source.The Reflectivity ratio is different when different surface conditions and different materials. Penetration with the nature and thickness of the material varies.Different materials have different effective penetration.Penetration of non-transparent material usually regarded as zero.in General metallic crystals are very dense,the electromagnetic radiation from the surface can rapidly decay in a very short distance,so heat radiation penetration depth on the metal is micrometer level.The molecular structure of the non-metallic material is not very dense,therefore, when the incident electromagnetic wave reaches the interface, electromagnetic wave is rarely reflected, easily pass and into the surface,When passing through the full thickness only,unabsorbed radiation energy can be pass.Therefore, the non metal’the penetration depth is high than metal.Superiority and efficiency of Infrared heating, the user accept infrared drying heating method in recent years(Infrared with the amazing speed of development), mainly advantages of infrared drying method has the following advantages:
1. With the penetrating power, and can produce heating both inside and outside.
2 Not need the heat transfer medium to passes, thermal efficiency is good. 3 can be localized heating, save energy.
4 To provide a comfortable working environment.
5 to save the construction cost and space, combination, installation and maintenance simple and easy.
6 heating process is clean.
7 temperature control is easy, and the temperature rise rapidly, and is relatively safe.
8 thermal inertia is small, do not need to preheat, save manpower.
Because infrared heating has the advantages and therefore to obtain high efficiency and uniformity of heating is possible and get high quality products
