ir infrared is Important role in the touch screen  

The 808nm200mw far ir infrared light covered the full touch screen, the laser red outside thickness probably about 2mm, fingers or other objects close to the touch screen,ir infrared form infrared plane are reflected, forming a bright spot, the tip of the finger will be infrared point is displayed. The infrared camera to capture these bright spots, and pass a pictures of screen to the computer, computer processing and analysis of these images, identify the touch event and the position, and then call the corresponding instruction, provide feedback, and produce a new image, and then the new image onto the projection soft screen through the projector projection.

Infrared led plays an important part in people’s life.
Therapeutic effect with infrared 

Infrared can improve blood circulation, increase phagocytosis, reduce swelling, promote inflammation dissipated, the treatment of chronic inflammation.

More infrared everyday applications

Infrared applications in daily life is also very extensive, high-temperature sterilization, monitoring equipment, the phone’s infrared port, the hotel door cards, TV remote control, However,
But the broader ir led market in the us appears brighter.
,other words ,it already has success in the app space.

What is difference between the isolated of LED driver and non-isolated of LED driver?
The work flow of Isolation of LED driver as follow:
Input power 110Và rectifying à filtering  à switch transistor of ICà High-frequency transformerà  geted output voltage.The contact is isolated between the output side and input side by transformer. so the security.
Non- isolated LED driver is used capacitance + Resistance To reduce the voltage. But it still has high voltage(with input 11V) after reduce the voltage.

used in the low voltage led lamps,the lamps have 110V, who had touched the danger of electric shock.Very likely People is danger of electric shock when touched the led lamps.

Summary:

Non isolation: input and output power of common ground.

Isolation: input and output power with no common ground, a transformer separated.

 Ir led strip can be done barbecue?

Infrared wave has longer lengths (radio, microwave, infrared, visible light. Wavelength  in order from  from long to short），the impression is feeling the heat, the effect is produced by thermal effects,
what kind of level is reach when then the infrared transmission? If the infrared can penetrate to theatomic, molecular internal, so will cause the atomic, molecular enlargement and can lead to the disintegration of atoms, molecules. This is really the case? As a matter of fact? Infrared frequency is low, the energy is not enough, the ir led could not achieve effect that atomic and molecular disintegration .
Therefore, the infrared can only penetrate the gap of the atoms and molecules, and can not penetrate to the internal of atoms, molecules. because the infrared can only penetrate into the interstitial of atoms, molecules, will cause the vibration of atoms and molecules to accelerate, distance to big,
increasing the thermal energy, from a macro perspective, the material in the melting and boiling in, on vaporization, but the nature of matter (atoms, molecules themselves) did not change,this is the infrared thermal effect. So we can use this infrared excitation mechanism to barbecue food, make organic polymer degeneration, but cannot use the infrared ray generated photoelectric effect, but can not make the nuclear internalchange.

Automotive painting with ir led strip
Wall hanging type ir led strip

Spray paint When the car repair,generally use two-component paint, ensure the bright color, and not easy to fade. This paint chemical reaction depends on its Chemistry molecular to the drying and heating, the effect is not very good.
Far infrared penetration is very strong, can enter the paint layer directly, from inside to outside to finish drying process in a very short period of time, at the same time to keep intact paint colors of primary.because of the ir led strip has a distinctive character in the far infrared,
based on the combination of advanced technology developed on the baking equipment, to paint domain introduction of infrared heating technology, which has a strong penetration wavelength straight into the paint, so that the paint layer(body shell) temperature rises rapidly generate self-heating effect,coating moisture (or solvent) is rapidly from the inside to the outside, when the volatile chemical paint is same,paint bond resonance surface increase due to aggregation amplitude,so that the probability of vibrational frequencies draw the
crosslinked polymer is increased,the acceleration curing of  lacquer paint. Ensure that the paint drying and heating should have high efficiency, environmental protection and energy-saving features requirements. Therefore. The gloss of paint surface and high fullness, mirror more clear, coating adhesion, is not easy to produce the “orange peel, tears” phenomenon, avoid rework, cost savings, improve efficiency.
