[UVLED Feature] UVLED Has These Features

UVLED (UV light diode) luminous mechanism, efficiency, and characteristics are now not limited to high -pressure mercury lamps and halogen lights. The technological progress of semiconductors has allowed ultraviolet light diode to light color in various industries. And based on the characteristics of low energy consumption of ultraviolet light diode itself, it makes the process that was not suitable for ultraviolet curing, and it also became particularly simple and practical. However, do you really understand this ultraviolet light emitting diode? Let s take a look at it: UVLED is the ultraviolet light emitting diode, which is also a type of LED. , That is 365-405 wavelength. UVLED light emitting mechanism: The end voltage of the PN knot constitutes a certain potential barrier. When the positive bias voltage decreases, most carrier in the P and N areas spreads to the other party. Because the electronic migration rate is much greater than the air acupoint migration rate, a large number of electronic spreads to the P area, forming an injection of a minority carrier of the P area. These electrons are compounded from the cave on the price, and the energy obtained during composite is released in the form of light energy. This is the principle of PN knot glow. UVLED luminous efficiency: Early component development is concentrated in improving its internal quantum efficiency. The main method is to improve the quality of the barrier crystal and change the structure of the barrier crystal, so that the power energy is not easy to convert to the thermal energy, and the UVLED luminous efficiency is indirectly improved, so that the luminous efficiency of UVLED can be obtained. About 70%of the theoretical internal quantum efficiency, but such internal quantum efficiency is almost close to the theoretical limit. UVLED electrical characteristics: UVLED electrical characteristics --- The relationship between current and voltage UVLED electrical characteristics --- UVLED voltage and temperature relationship UVLED electrical characteristics --- UVLED light-emitting angle current control device, load characteristics are similar to PN PN The UI curve of the knot, the minimal changes of the positive direction voltage will cause a lot of changes in the positive current (index level), the reverse leakage current is small, and there is a reverse breakdown voltage. In actual use, you should choose. UVLED's positive voltage becomes smaller with the temperature increase, with negative temperature coefficients. UVLED consumption power, part of the transformation into light energy, this is what we need. The rest will be converted into heat energy, so that the knot temperature is increased. UVLED optical characteristics: UVLED provides a large monochrome light with a large semi -width. Because the energy gap of the semiconductor decreases with the temperature, the peak wavelength it emits increases with the rise of the temperature, that is, the spectrum red shifts, that is, the spectrum red shifts, that is, the spectrum red shifts. The temperature coefficient is2 3. UVLED luminous brightness L and forward current. The current increases and the light brightness is approximately increased. In addition, the brightness brightness is also related to the environmental temperature. When the environmental temperature is high, the composite efficiency decreases, and the light emitting intensity decreases. UVLED thermal science characteristics: UVLED thermal characteristics --- Under small current between UVLED wavelength and temperature, UVLED temperature rise is not obvious. If the environmental temperature is high, the main wavelength of UVLED will be red, the brightness will decrease, and the luminous uniformity and consistency will become poor. In particular, the temperature and stability of the reliability and stability of LEDs on LEDs are more significant. So the cooling design is critical. Tianhui Technology Development Co., Ltd. uses the original imported lamp bead, which has a small impact on the temperature environment and high product quality. The commonly used curing devices include UVLED wire light sources, UVLED face light sources, and UVLED dot light sources. Its application involves the UV curing technology of various industries. If you just need to adjust your UV curing technology, you may wish to get in touch with Tianhui. I believe there will be different gains! http: ///list-19-1.html

UV LED curing is a technique that employs ultraviolet light to cure or harden substances. This procedure involves exposing the material to UV LED diodes emitting UV light. When UV light strikes a substance, it initiates a chemical reaction that causes the substance to harden or resolve. UV LED diodes emanate UV-A, UV-B, and UV-C light, which correspond to the wavelengths required to initiate the curing process.
Throughout the years, ultraviolet (UV) light as a disinfectant has gained popularity. UV LED has been used as a UV LED solution that is capable of killing a variety of microorganisms, including bacteria, viruses, and mold. It is also known as UV LED Disinfection process.
As summer approaches, so does the pesky problem of mosquitoes. These tiny insects can ruin a peaceful outdoor evening, leaving us with itchy bites and disease risk. Fortunately, there's a solution in the form of UV LED mosquito traps. These devices use the power of ultraviolet light to attract mosquitoes and other flying insects better.
Are you aware of the latest findings on the transmission rate of the new coronavirus? A recent study has uncovered a shocking discovery- the air transmission rate of the virus may be a staggering 1,000 times that of the contact surface! This means the virus may spread faster and farther than we previously thought. Keep reading to learn more about this groundbreaking research and what it means for our fight against the pandemic.
UV LED printing system is a cutting-edge technology that has revolutionized the printing industry by offering faster printing speeds, improved print quality, and increased energy efficiency. However, like any technology, it has its own pros and cons.
