1. Storage moisture-proof is very important for the normal use of LED lamp beads. In any case, LED lamp beads should be stored in a dry and ventilated environment. The storage temperature is -40 100 . It is better to use LED lamp beads within 3 months under its original packaging conditions, so as not to rust the bracket. When the packaging bag of LED lamp beads is opened, it should be used as soon as possible. At this time, the storage temperature is 5 28 , and the relative humidity is 60%as follows. 2. Cleaning can not use unknown chemical liquid to wash LED lamp beads, which may damage the appearance of LED lamp beads and even cause collagen cracking. If necessary, soak the LED lamp beads at the alcohol at room temperature. Time should Stimulate within one minute. 3. Do not take shape during welding or after welding. Remember that any behavior of squeezing resin may damage the golden line inside the LED lamp bead. 4. When welding is welded with LED lamp beads, do not apply any external pressure to the lamp body. Otherwise, it may break inside the LED lamp beads, which will affect its internal golden wire connection and cause quality problems to cause quality problems. The colloid must not be immersed in the welding. When welding, the welding point must have at least 2 sisters from the lower edge of the colloid. If the LED lamp beads are uniformly launched with a soldering iron, do not weld the two pins of the uniform LED lamp beads at the same time. What else must be noticed is that the welding temperature or improper time control may cause LED lamp bead lenses deformation or the internal opening of the core of the lights and cause the dead lamp. 5. It is recommended to use the essentials in the process of use, whether it is single or multiple in use, the driver current of each LED lamp bead is recommended to use the IF range. The instant pulse will destroy the internal fixed connection of the LED lamp bead, so the circuit must be carefully designed, so that when the online road is closed, the LED lamp beads will not be impacted by overvoltage (overcurrent) shock. LED lamp beads require the consistency of light and brightness and color when used in multiple uses. Under normal conditions, the consistency of the color of the LED lamp beads and the brightness of the brightness. 6. The protective static electrostatic static electrostatic can cause LED lamp beads to effectively lose effect, so during the use process, it is necessary to avoid the damage to LED lamp beads. 1. LED lamp bead detection and assembly must wear static uniforms and anti -static gloves. 2. Welding equipment and testing equipment, tables, storage racks, etc. must be used for use. Three imported LED lamp beads, using ionic fan to eliminate LED lamp beads during storage and assembly during storage and assembly. Fourth, the ingredient box containing LED lamp beads uses anti -static ingredients, and the packaging bag uses a static bag. The phenomenon of LED lamp beads damaged by electrostatic damage will appear: 1. Inverse leakage, light will cause a reduction in brightness, and in severe cases, the phenomenon of death will occur. Second, the voltage value becomes smaller. LED lamp beads can't shine during low -current driving.

In order to maximize the electricity conversion rate and heat dissipation efficiency of high -power LED street light lighting boards, the design of LED high -power chips is used to expand the area of LED high -power chips, and the electrode optimization technology increases the amount of LED chips. , Make the chip surface the heat flow evenly, the chip work is more stable. Analysis of the packaging process of high -power white light LEDs to improve chip lighting rate, guarantee white light quality, and device heat dissipation technology. Based on the results of the above technology and finite element analysis software on the thermal resistance analysis results of high -power LED devices packaging, the array assembly technology of the COB (Chip On Board) LED chip was determined to create the best technical solution for the manufacture of LED street light lighting boards. LED chip knot temperature is easy to control below 120 C, and good compatibility with external heat dissipation technology. The best distance between the LED high -power chip array chip was calculated through the best backing mathematical model of light. Finally, through the comparison of various high -power white light LED drive solutions, the best driving solution for the white light LED is determined to adjust the brightness for the broad current drive arteries (PWM). At present, more and more LED lamps have replaced traditional lighting lamps, and are used in lighting display, advertising lighting, underwater lighting, architectural lighting, street lights and other applications. Our government has been“Energy conservation”As a national policy. With the country“Energy conservation”The project is carried out in depth,“Green Lighting Engineering”It has been listed as a key promotion project in my country and the cross -century strategy of energy -saving industries. China's lighting industry has entered the watershed of industrial upgrading. In the context of calling for lighting energy conservation and emission reduction, high -efficiency and energy -saving LED products are the focus of industrial upgrading.“The beginning of the new revolution in the lighting field”It integrates many advantages such as environmental protection, long life, high -efficiency energy saving, high color rendering, non -frequent flashes, non -ultraviolet rays, no mosquito, instantaneous startup, wide voltage work range, large width working temperature range and other advantages. The advantage of environmental protection is the leader of energy -saving lighting products. If 10%of the traditional light sources in my country are replaced by LED each year, they can save 9 billion kWh, which is equivalent to 8.64 million tons of carbon dioxide. At present, LED high -power lamp lighting products have also penetrated into all areas of social life. The following is a few commonly used lamps, compared with LED lamps to quantify the advantages of LED lamps. LED lamps advantage comparative quantitative table (commercial electricity: 1.2 yuan/kWh) Jinghan Optoelectronics discussed with you to discuss the advantages of LED lamps in energy -saving transformation by the above table. Consumption. For the current energy -saving lamp or solar lamp tube, the energy saving efficiency is also more than 50%, and the harmful and fatal substances in the energy -saving lamp or solar tube are completely avoided——HG. The crushing of a 36W solar lamp tube may cause the mercury steam content in the surrounding air to exceed 2000 times the national standard; and some scrap lamps are not treated properly, and the mercury contained in the underground. It is a huge harm to the ecological environment. LED lights can not only face the increasing energy crisis, but also provide an important way for the purification of the ecological environment. Therefore, the potential of LED lighting in energy -saving transformation is huge.

The full name of the LED is semiconductor emitting diode, which is made of semiconductor material. Its functional principle is to directly transform electrical energy to optical energy, and the electric number is transformed into a light signal light -emitting device. Its advantages are: low consumption, high brightness, rich color, strong vibration resistance, long service life (normal glowing reaches 80,000 to 100,000 hours), cold light source, etc., can be said to be real green lighting. The lighting products with LED as the new light source will definitely replace white weaving lights in the future of the 21st century, becoming another revolution in human lighting. LED lamp beads use low-voltage power supply, and the power supply voltage is kept between 2-4V. According to the difference in product, LED lamp beads are a high-voltage power supply than the application of high-voltage power, which is especially suitable for application in public places in public places. The composition of colorful LED lamp beads includes red (R), green (g), and blue (b) three -base color LED. Everyone is familiar with two -color LED. Usually consisting of red light LED and green LED. It can independently emit red or green light. If the red light and green light are highlights at the same time, the two kinds of light of red and green will be mixed into orange -yellow. The principle of discoloration of the discoloration lamp is when three basic LED lights up with two LEDs, it can emit yellow, purple, cyan (such as red and blue LEDs when lighting out of purple light); If the three LEDs of the blue light at the same time, it will produce white light. If there is a circuit that can light red, green, and blue light LED respectively, light up, and lit with three base colors alone, then seven different colors of light can be emitted, so the phenomenon of colorful LED lights appears.

There are often various solidification phenomena in UV curing technology. The most prone to bad phenomenon is the following. However, sometimes the reason for the poor curing is comprehensive. In other words, sometimes 2 or more solidified phenomenon occurs at the same time in the same product. The specific solution is to contact the technical personnel of the manufacturers of UV resins, UV mercury lamps, product materials, and UV curing machines first, or completely detect the real cause of the phenomenon of solidification. Effective solution. The concept of poor solidification, so -called solidification, means: first, there is no complete solidification state, that is, the state of not hardening; second, the state of excessive solidification, that is, overcured. If the phenomenon of hardening occurs, it will be burned by the cure, or the heat change phenomenon will occur due to the high calorie of the curing bin. If the phenomenon of unseenized phenomenon is because the resin is not completely solidified, the product is sticky, the adhesive force will be significantly reduced, or the resin solution that is not solidified on the surface of the product. 1. Product thermal deformation heat does not have much effect on metal or wood, but the thin plastic series of film or film products is very sensitive to heat. The calories are extremely sensitive, so it can be said that the top priority in the work of solving product thermal deformation in this field. 1) Wave: Thermal deformation is primary stage. 2) Curl: Start partial deformation. 3) Shrinkage: serious local deformation. 4) Carbonization initial stage: all turn yellow, black, and severe thermal becomes serious. 2. Although the adhesive effect seems to have completed the curing process, the adhesion effect between the materials and the coating is not good. It may be scraped with a nail or coin gently, the curing layer will be scraped off, and the cross -cutting test cannot be tested. Mobile parts, LCD display parts or films, COG/BGA and other chip components must be very firm. 3. Swaging, Bulging) The mother material that needs to be painted is like plastic or rubber, which is very sensitive to thermal material. Part of the mother material or resin will swell out due to heating when curing. , It will cause the phenomenon of burning of the mother material or resin. The expansion of the internal and external bending is severe, and the phenomenon of bubbles appears inside, so that the appearance after solidification will not look good. This kind of bad appears in the optical film and mobile phone display flat solidification. 4. Bubbling (Bubbling, Air Bubble) film, high -quality film and other precision films, although the solidification and bonding can be fully completed, if you observe it with a microscope, you will find that there are fine and micro -cracks existing. The reason for it has not yet been concluded, which is also the phenomenon of bad product that is difficult to solve. We believe that this is the result of the crystal of the resin in the horizontal distribution after the resin is solidified. 5. Surface crack film, high -quality film and other precision film. Although the solidification and adhesion can be fully completed, if you observe it with a microscope, you will find that there are fine and micro -cracks. The reason for it has not yet been concluded, which is also the phenomenon of bad product that is difficult to solve. We believe that this is the result of the crystal of the resin in the horizontal distribution after the resin is solidified. 6. The phenomenon of yellowing is a phenomenon that occurs more when solidifying on transparent resin. You can reduce the phenomenon of yellow change from adding yellow changes in the composition of resin to reduce the phenomenon of yellow change. 7. Film non -dry glue ink printing commonly used thin -film non -drying materials are: polyethylene, polypropylene, polyester, polyvinyl chloride, polystyrene, polyolefin, etc. But the difference is that the film is not absorbed. Therefore, the printing of the film does not dry glue mainly uses UV convex marks and UV soft printing. However, in the process of printing and processing, the problem that label printing companies often encounter are the insufficient paste of UV ink on the surface of the film. The solidification has a great impact on the stretch strength. With the increase of the curing of the adhesive, the cross -linked density increases, the average molecular mass of the cross -linking point becomes smaller. If the epoxy and polyurethane acrylics are coordinated, the adhesion will be greatly enhanced.

At the South China printing exhibition ended at the Guangzhou Convention and Exhibition Center this year, it is easy for us to find that many printing devices are equipped with UVLED curing light sources. The application of UV LED curing in printing is a process of solvent without ink. Volatile organic substances can reduce environmental pollution. With the implementation of the WTO's prohibition of mercury, more and more printing equipment will change the previous mercury lamp to UVLED. Our company has done UVLED curing equipment for more than ten years. It has deep technical precipitation and a group of high -tech talents to provide customers with efficient and reliable UVLED curing devices.
