Is it right for the Electromagnetic radiation has an important effect on human health?

Is it right for the Electromagnetic radiation has an important effect on human health.
The Electromagnetic radiation is one of the ordinary elements in the nature. It has a century-long reputation of being poisonous was right after all While succinct, the above question a lot of questions unanswered. So all people want get a answering questions quickly and succinctly. might better be “Yes” or “No”. However tough questions, actually has many factor in here. Such as The electromagnetic wave frequency, intensity (please see pic as follows)and differences for human ‘physical, etc.
Specturum

If everyone was forced to summarise my answer, This is possible, If the Electromagnetic radiation is higher than a certain level may lead to harmful for the human’body, as for the Electromagnetic radiation as low-power; There was no evidence to proof that possibly hurt our body will do small harm to human health.

LED strip with Anti-ultraviolet

LED strip with Anti-ultraviolet
There are two color of LED strip with Anti-ultraviolet, one is yellow other is white. can effectively that ultraviolet rays under 400~500nm. These are normally widely used for unwanted ultraviolet rays’ place. such as : semiconductor factory, electronic archives, libraries, museums, art galleries, art galleries, exhibition shop, printing ink for color inspection, antique warehouse, food production workshop etc.

* Yellow led strip with Anti-ultraviolet
During the Producing of semiconductor , there was no ultraviolet rays under 500nm. The Yellow led strip with Anti-ultraviolet  without ultraviolet rays under 500nm. And these led strip are very energy efficient, long server time.So it’s good for Communication, bio-tech, new material industry photoelectron technology and high efficient energy saving technology

* White led strip with Anti-ultraviolet
The White led strip with Anti-ultraviolet has not ultraviolet rays under 400nm. Specific energy-efficient, long life, quality and stability is an indispensable quality of space embellishment.

Definition for uv led strip

Definition for uv led strip
The ultraviolet rays are one of the electromagnetic wave, the electron atoms jump from the high-energy bands at low energy band, will release excess energy with electromagnetic waves . The stronger the energy of electromagnetic wave , the short the wave you can . the human can see that400nm-780nm(1nm=10-9m),
The 400nm of electromagnetic wave will shows “ blue ” color,
The 780nm of electromagnetic wave will shows “orange” color.
The wavelength of ultraviolet rays are smaller than 400nm. The wavelength outside the ultraviolet rays area, , it is known as Ultraviolet, the wavelength of UV as 100-400nm, These rays would not be visible to our eyes. But the cameras can see what human eyes can ‘ t: The ultraviolet rays.

many user(inquiring mind) think about this all the time. What is the material that makes this led?
However that is also very important for led manufacturer. Because The use of the correct materials was crucial.

LED DROOP

LED DROOP
The blue LED Illuminate yellow fluorescent powder got a white LED. This is the origin of white LED. First we gave a brief analysis of LED DROOP . there are have two reason . a reason for some self reason . the blue led droop is fast than RED LED ,YELLOW LED AND GREEN LED.Other reason from fluorescent powder DROOP. The led fluorescent powder DROOP will be serious in high temperature.
Concretely, this reason includes the following two parts,
Quality problems:
*LED chip have a quality deficiency issue make brightness DROOP is fast.
*Production technology has been faulted
The LED not used correctly:
*It is better to use constant current to drive led. Because the voltage drive make LED DROOP is fast.
* Driving current can be overly ambitious. Even the current is larger than requirements of Technical Specification.

LED’usage recomendations

LED’usage recomendations
As a single led and as multiple led, we are defined by IF(range is 10mA-20mA) on led spe sheet. The LED short circuit currents of bulk electric are very high. it’s Mable destroy the LED when restart the led initially.The user must be carefully that designed to avoid over voltage (over current) for a start, keeping the color and brightness consistency in 20 mA .
That said, To obtain uniformity of brightness and color, should use the same current and same batches. Because of the different batches of LED Have different performance characteristics. It’s to cause differences in brightness .

Topic of preserving a led(achieve moistureproof)

LED how to preserving (or moistureproof)led module— All the user are concerned with the topic of the Secure the working.today we simply talk about this topic

In order to avoid moisture, LED should be stored away from wet place,Try to decide on fittings dry and ventilated environment, the storage temperature for -40 degrees C – +100 C, relative humidity below 85%.After unpacking, immediately use is best,Tidying up the remainder of led module to original packaging, about it we are expected to run out in less than four months. One more time to say that please settle your led module as quickly as possible when open the packaging. Becase of the storage temperature for 5 C -30 C at this moment , the relative humidity below 60% .Do not use the unknown chemical liquid to clean the LED module, because that might will damage the LED resin surface, even causing colloidal cracks.
if necessary, pleas to clean the LED module with alcohol or fluorine wrapped at natural temperature . the cleaning time within one minute.

High power led bracket of materials

High power led bracket of materials

The different power led using several different led bracket. Small power adopt PPA、 medium power using PCT、some high power led were equipped with EMC . All plastic materials has water absorption . led module have to be  Dehumidification when using the led module. electroplated coatings is a key process in manufacturing led bracket. The step are directly related to the  luminous flux and welding performance.Choose a best bracket is paramount to the development work in high power led.

High power led bracket of materials
medium power led is much better for the using copper material . most high power led module are now already made by Direct Bonding Copper.
