At present, the luminous body of the UVLED curing machine on the market is ultraviolet UVLED lamp beads. The UVLED curing light is composed of one or more Ingan quantum traps in a thin GAN sandwich structure, and the source area formed is. By changing the relative proportion of Inn-GAN in the Ingan quantum trap, the launch wavelength can be changed from purple light to other light. Algan can be used to make the cover layer and quantum trap layer in UVLED by changing the ALN ratio, but the efficiency and maturity of these devices are poor. If there is a source quantum trap layer is GAN, which is relative to Ingan or Algan alloy, the spectral range of the device emitted is 350 370nm. When a short electronic pulse at the blue inflection diode pump, ultraviolet radiation is generated. Aluminum -containing nitrogen, especially Algan and Algainn can make short -wavelength devices, obtain a series of wavelength UVLED. Most of the domestic manufacturers still use traditional ultraviolet mercury lamps to work. However, due to the characteristics of UVLED long life and no radiation, its application is also becoming more widely widely used.

Directly inserted LED lamp beads in the process of welding, please strictly abide by the following requirements: 1. Be sure to wear anti -static gloves, anti -static wrists, etc. during actual production. Only lead. Because the humidity of the human body on the workbench is 60%-90%, the static electricity of the human body will damage the crystal layer of the LED lamp beads. After a period of time, the LED lamp beads will show failure and dead lamps. 2. Welding temperature is 260 C, 3 seconds. Too high temperature and too long will burn bad chips. In order to better protect the LED lamp beads, LED lamp beads and PC boards should be kept at a distance of more than 2mm to make the welding heat dispel. 3. The normal operating current of the direct -inserted LED lamp bead is 20mA, and the micro fluctuations of the voltage will cause a large fluctuation of the current. Therefore, during the design of the circuit design, different current -limiting resistors should be paid according to the voltage and deployment of LED lamp beads to ensure that the LED lamp beads are in the best working state. When the current is too large, the LED lamp beads will shorten the life, the current is too small, and the required brightness requirements cannot be met. Our company will split the LED lamp beads when batch supply, that is, the LED lamp bead parameters in the same pack of products are consistent, ensuring the consistency of the actual product. At present, the more common LED lamp beads welding method: 1. Single iron welding: the tip of the tip of the soldering iron does not exceed 300 C, the welding time does not exceed 3 seconds, and the welding position is at least 2mm from the colloid. 2. Summit welding: The maximum temperature of soaking welding is 260 C, the welding time does not exceed 5 seconds, and the soaked welding position is at least 2mm from the colloid. Directly inserted LED lamp bead welding curve pins method: 1. Must be 2mm from the collagen to bend the bracket. 2. The formation of the bracket needs to ensure the pins and spacing consistent with the line board. 3. The formation of the bracket must be done with a fixture or by a professionals. 4. The formation of the bracket must be completed before welding.

LED lamp beads have many strengths such as energy conservation and environmental protection. Following the reduction of LED lamps quotation, these years, LED lamps have slowly entered the vast home lighting and lighting market. And more and more wide. So, what are these infrared LED lamp beads on the lamps? First of all, in addition to the primary use of infrared LED lamp beads on the scene lighting shopping mall, including: construction decoration, interior decoration, tourist attractions and other lamps, it can also be used on the primary construction, big streets, business centers, famous monuments, bridges, communities, yards , Lawn, home, leisure and entertainment, decoration lighting fixtures, and commercial lighting lamps that are integrated and advertising. Secondly, the infrared LED lamp beads are first used on the car lamps. Car shopping malls are infrared LED lamp beads using fast -developed lamp shopping malls. They are mainly used in the instrument panel, air conditioning, audio and other indicators and internal reading lights. Wait. Again, infrared LED lamp beads also have many use in the backlight shopping mall. For example, infrared LED lamp beads have been used in many fields such as mobile phones, computers, handheld electronic products, cars, aircraft dashboards and other fields. In the end, infrared LED lamp beads also have many use in traffic lamp malls. It is precisely because infrared LED lamp beads red, yellow, and green LED have high brightness, long life, and power saving. The LED light source has the characteristics of seismic resistance, weather resistance, good sealing, low heat radiation, small volume, and easy to carry. It can be widely used in special operations such as explosion -proof, field operations, mines, military operations, etc. In the process of the curing process of deep ultraviolet LED lamp beads, the oxygen resistance aggregation has always been confused by everyone: when the light is curing in the air, the oxygen blocking effect often causes the bottom layer of the coating. Oxygen blocking can cause the surface layer of the coating to present a lot of oxidative structures such as hydroxyl, cymbal, and peroxy groups, and then affects the long -term stability of the coating, and may even affect the hardness, gloss and resistance of the paint film after curing. Function. Why? The basic state of the material is single -line, but the stability of O2 is three -line state. Therefore, it consumes free radicals with the aggregation response competition of free radicals. Because the vast majority of optical curing technology is performed in the air environment, and the primary application is data such as coatings and inks with a large appearance/volume ratio, O2 has a free radical polymerization response to the free radical polymerization of optical solid data. Concentration. Especially when the thickness of the coating film is thin, the concentration of oxygen in the oily organic system is generally less than or equal to 2 10-3 mol/L. Not only does the dissolved oxygen molecule in the formula obstruct the aggregation, in the process of light, follow the oxygen in the solidification system. The consumption of the molecule, the oxygen in the appearance of the coating air can also be scattered into the coating agile, continuously obstructing the aggregation. The oxygen concentration of the system Chinese dissolved in China is very low, which is easier to consume. Regarding the closing system, the process of primary activity free radicals consuming oxygen is basically equivalent to the aggregate induction period. Relatively speaking, oxygen from the outside world to the inside of the coating is the primary cause of obstruction of aggregation. Oxygen blocking also occurs simply in the superficial layer or all of the thin coating, because in these areas, the oxygen molecules in the environment are more simply.
