UVLED, that is, UV light light diode, is a type of LED. It is a high -power LED chip with a high -power LED chip with a certain proportion of 200nm to 450nm. The main principles of UVLED are the following points: 1. UVLED emitting mechanism: The end voltage of the PN knot constitutes a certain potential barrier. When the positive bias voltage decreases, most loaders in the P and N areas spread 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. 2. UVLED light emitting efficiency: Generally called the external quantum efficiency of the component, it is the internal quantum efficiency of the component and the product of the component efficiency. 3. UVLED optical characteristics: UVLED provides a large monochrome light with a large semi -width. As the energy gap of semiconductor decreases with the temperature, the peak wavelength it emits increases with the rise of temperature and increases with the rise of temperature. 4. UVLED thermal science characteristics: Under a small current, LED 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. 5. UVLED life: The long -term work of UVLED will cause aging, especially for high -power UVLEDs, the problem of light decay is more serious. When measuring the life of UVLED, it is not enough to use the damage of the light as the UVLED life. It should be used to specify the life of LED with the percentage of UVLED attenuation percentage. There are many characteristics of UVLED, but the main summary is the following points: 1. There is no solvent-greenhouse effect 2. It is conducive to environmental protection 3. Work-oriented land without pollution 4. Fast production 5. room temperature curing 6. Products have unique performance 7. Save energy 8. Easy washing 9. Save space 10. High gloss 11. Little waste materials 12. Method diversity, adaptability, product replacement fast. Because of so many characteristics and characteristics of UVLED, it has laid the foundation for the later use of UV solidification.

In recent years, with the rapid development of the UVLED industry. The chip has always been the technology core of the UVLED industry. Then the development of chip development and quality directly affects the development speed and maturity of the UVLED light source industry. UVLED has been pursuing high performance development. The pursuit of high luminous efficiency has always been the driving force for the development of LED chip technology. Installation technology is one of the main technologies that currently obtain high -efficiency and high -power LED chips. Sapphire in the substrate material and the vertical structure of the vertical structure (LLO) and key combination technology of the supporting vertical structure will still occupy the rule for a long time. status. Photon crystals and AC LED technology will be a technical technology for future potential. In the near future, the new metal semiconductor structure is adopted to improve Ohm contact, improve the quality of the crystal, and improve the electronic migration rate. Improve the shape of the LED chip, the surface thickness and the photon crystal, the high reflectivity mirror, the transparent electrode, the extraction efficiency can be 90%. At that time, the total efficiency of the white light LED can reach 52%. With the improvement of UVLED light effects, on the one hand, the chip is getting smaller and smaller. In a certain size of the outer chip, the more the cut chip can be reduced, thereby reducing the cost of a single chip, reducing the price of the price. If 6mil appears. On the other hand, the power of the single chip is bigger, such as 3W, 5W, 10W development. This can reduce the number of chips in applications such as the lighting of power demand and reduce the cost of the application system. Under the pressure of market competition, if the UVLED industry wants to truly break through the bottleneck of development and active rights in the market, it must have a strong chip technical advantage in order to have the driving force for development. At the same time seize the market opportunities, adjust the company's market and product positioning, highlight your advantages, and jointly develop and expand the future prospects of the market.

Infrared lamps are very helpful for night vision monitoring, but how to extend the life of infrared lights to become recognized as a recognized problem. Below, come to understand with the editor. The service life of a single LED infrared lamp is still relatively long, but the number of LED infrared lamps on the infrared lamp in the infrared camera (including 32PCS, 36PCS, 42PCS, etc.). Therefore Overall calories. If the heat dissipation is not good, the aging of infrared cameras will be too fast, thereby reducing the life of the infrared camera. If the temperature continues to be too high, it will damage other accessories of the infrared camera. According to the above analysis, we can know that too high temperature is the main factor that causes the short life of LED infrared lights. If it does not affect the effect of infrared irradiation, the service life of LED infrared lights should be improved. The design and reasonable match of the component are very important. First of all, choose high -power, low -current LED infrared lights when choosing. This not only guarantees the brightness, but also does not have a large current, causing the overall temperature of the infrared camera to increase. Second, for the application of the substrate, the aluminum is a good choice. Compared with other metal characteristics, aluminum metal has a good heat dissipation function. Therefore, while ensuring the constant temperature, it can also save the negative impact of the cooling fan. Again, it is the problem of reducing the exposure of infrared lights. Install an aluminum metal plate in the middle of the LED infrared light and the lens to prevent the LED infrared lamp's light interference problem. In addition to the improvement of technology, the cooperation of the environment is also very important. For example, using metal film reflection, using high -efficiency optical lenses, etc., can achieve the growth of lighting capacity, thereby reducing the work pressure of infrared lights. In addition, using a stable current and realizing the separate power supply of the lights can reduce the damage caused by the unstable power of the power, or remove the overall infrared light due to a small amount of infrared lamp problems.

As the application field of UVLED curing machines has continued to expand, some friends who have not been exposed to UVLED before, they also started to consult Tianhui about UVLED curing machines. Many friends do not know the problem of UVLED bands, and which one of their products applicable Band curing machine. In fact, the common bands of UVLED are 400nm, 395nm, 390nm, 385nm, 380nm, 375nm, 365nm, 310nm, 254nm, etc. Among them. Today, Tianhui will let you talk about which industries are suitable for UVLED curing machines with 365nm bands! In UVLED, the ultraviolet light of the 365nm band belongs to pure ultraviolet light output, monochrome light does not contain infrared rays, avoiding the influence of radiation from the light wave band in 350nm 400nm. The UVLED curing machine with a band of 365nm is not contained in infrared and thermal radiation, which can effectively reduce the temperature rising temperature of the workpiece. It is very suitable for technological applications that require low temperature, high precision, and minimum thermal deformation, such as optical lens assembly, etc., and generally solidify The band of UV glue is also 365nm. It should be noted that if you use UVLED solidification machine to curing UV glue, you need not only consider the problems such as the band, strong light, and irradiation area, but also the matching of the curing machine and glue. Okay, the solidification effect is not ideal. At present, the UVLED curing machine of Tianhui is very high on the UV glue matching of multiple brands.
