In the actual use of customers, such problems often occur, that is, I do nt know if the radical intensity of its own UV curing machine is suitable. Today, Tianhui will talk about the main factors that affect the irradiation of UVLED cold light source curing machines. UVLED curing principle I. The characteristics of the characteristics of UVLED cold light source curing machine by UVLED solidification material, decided to enter the cured material emitted by the lamp to cause the light and cause the molecules. UV solidification determines the collision between photons and molecules, which can cause the molecules to spread evenly through materials. In addition to the characteristics of UVLED light sources, the solidified bears also have optical and thermodynamic characteristics. They interact with radiation energy and have a significant impact on the process of solidifying. UVLED's spectral spectral two, spectral absorption, light energy is the amount of ink absorbed into the wavelength within the gradually increasing thickness. The more energy absorbed near the surface, the less energy obtained. However, with the different wavelengths, the longer the wavelength, the more the penetration efficiency, the shorter the wavelength, and the less the penetration part. In terms of the actual production process, the 365nm wavelength UVLED ultraviolet rays It is much better for the watch, and the long wavelength or 405nm penetration is better than 365nm. The overall spectral absorption rate includes all from the influence of light cause, single molecular substances, clustering and additives including pigments. Third, the reflection and scattering are relative and absorbed. The light can be changed by the direction of the ink, which produces reflection and scattering. These factors have reduced the energy reaching the deep UV energy, but improved the solidification efficiency of the reaction. The change curve between UVLED temperature and wavelength 4. The temperature of the cooling system UVLED curing machine has a significant impact on the rate of curing reactions (that is, strong irradiation light). One of the important restrictions that affect the curing process. People who know the temperature characteristics of UVLED lamp beads must know that the higher the temperature, the higher the wavelength of UVLED will drift higher. For example, some domestic lamp beads, when they first use it, the solidification effect is good. Light for a while for a while. After that, as the temperature rises, the wavelength of UVLED lamp beads has changed. 365nm will drift in the direction of 370/380nm. There is no way to absorb the glue or ink of the cause, and naturally cannot complete the cross -linking translation between glue or ink molecules, reflects the macro perspective, that is, the glue and ink are not well -curing or have no solidification. Tianhui has served more than ten years for various industries. If you have questions about UVLED curing, please contact us at any time!

Glowing diode is closely related to various products in life today, and it is inseparable. Products that can often appear in the glow diodes include home decoration lights, computers, billboards, lights and indicators on the road, toys and other products. The most commonly used products are patch 2835 lamp beads. The patch LED is affixed to the surface of the line board, suitable for SMT processing, can be returned welded, and the patch -type LED solves problems such as brightness, perspective, flatness, reliability, consistency, etc. It has the advantages of strong vibration resistance, low welding point defect rate, and good high -frequency characteristics. It encapsulates more LED chips on a smaller area and uses lighter PCB and reflective layer materials to show that the reflective layer needs to be filled. There are fewer epoxy resins. By removing heavier carbon steel material pins and reduced size, the product weight can be easily reduced by half. The volume of electronic products is reduced by 40%, one 60%, and the weight is reduced by 60%, 80%, and finally makes the application more perfect. So how to distinguish its advantages of 2835 patching beads? 1. Look at the bead bracket, the difference between lamp bead bracket materials: At present, there are aluminum brackets, brass brackets, copper brackets, etc. on the market. , The price difference is dozens of times. Even if it is copper bracket, the price of silver plating is divided into high and low. The market is generally called a good bracket, most of which are made of brass silver plating. 2. The difference between the welding line material: The chip and the bracket use the gold wire welding method to complete the electrode connection. At present, there are two types of alloy lines and pure gold lines on the market. 3. The difference between the chip size: The size of the chip that is usually reported is MIL. If there is no high -power measuring microscope, it is generally difficult to distinguish. We can compare the size of the chip by calculating the area of the chip, such as 23X10, the area of the chip is 230 square MIL, and the size of the chip area is a good way.

The light -emitting diode is usually referred to as LED lamp beads, which are made of compounds such as 镓 (GA), arsenic (AS), phosphorus (P), nitrogen (n). When the electron and the cavity are compounded, it can radiate visible light, so it can be used to make a light -emitting diode. LED lamp beads are usually applied in circuits and instruments as indicator lights, or form or digital display. The luminous color and luminous efficiency of LED light -emitting diode are related to the materials and processes of making LEDs. At present, LED lamp beads with three colors of red, green, and blue light widely used. The wavelength range of different colors is also different. Generally, the PN pressure decrease can be determined to determine the wavelength color of the glow diodes. 1. What are the encapsulation structure of the two -color LED light -emitting diode?. The reason why the two -color LED light -emitting diode can emit two colors of light is mainly to pack two different colors of chips in the same bracket. Simply put, its structure is beside the tube core of ordinary monochrome emitting diode, and then install another color tube core. The two -color LED can be divided into two feet without polar two -color LED lamp beads, and two -legged co -yin -yang two -color LED lamp beads. Second, the luminous principle of the luminous diode of the influence of the influence of the inflexible two -color LED luminous diode is two pins. For example, there are two pins in the red and green non -polarized LED LED glowing diodes. Extreme and short foot welding, n pole and long foot welding. When the current flows from long feet to short feet, the red and green double -colored LED lamp beads work normally, and the green light does not work because the current flows from the short foot to the long foot, the green light bead of the non -polar red and green double -colored LED lamps is normal, the green light is normal Work, red lights do not work, so as to achieve the purpose of controlling the current flow of two colors of red and green. Three, three -legged co -yin -co -aode two -color LED lamp beads of light beads, three -legged two -color LED light -emitting diode, two different colors of tube cores share one pole. The three pins are different, and the longest public foot in the middle is the public end. Three -foot and two -color LED lamp beads can be divided into two types: common cathode and common anode LED according to the different polarity of the public end pins. So. How to distinguish between three -legged two -color LED luminous diode polarity? The distinction between the Communist Yin and the yang is mainly to see the positive and negative poles of the longest public end pin. If the public pin is negative, it is the Gongchen pole LED LED light -emitting diode. LED current generally flows from the positive electrode, and the negative electrode flows out. Back to list

LED lamp bead packaging can be divided into two different packaging forms: direct -inserted and patch LED light -emitting diode. The LED patch is also referred to as SMD LED packaging. Its luminous principle is to turn the current through the compound semiconductor. Through the combination of electrons and holes, the excess energy is released in the form of light to achieve the effect of glowing. In fact, it is also called LED. It can convert electrical energy into light energy. Like an ordinary diode, it is composed of a PN, and it is also one -way conductive. The glowing diodes are posted on the surface of the line board, suitable for SMT processing, which can be welded. The size of the lamp beads is smaller than the direct -inserted LED, so it is packaged in smaller space to pack more LED chips. Patching lamp beads solve the problems of brightness, perspective, flatness, reliability and consistency. Compared with other packaging components, LED patch lamp beads have great advantages, such as high -quality seismic resistance impact performance , Low welding point defect rate and high frequency characteristics.
