The three anti -lacquer three -proof contains mildew, moisture -proof, and salt -proof fog. It is generally used in the protection of electronic circuit boards and their electronic components. These circuit boards are generally used in more complex environments, such as industrial and mining instruments, kitchen appliances, outdoor street lights, etc. The three -proof paint is sprayed on the circuit board and electronic components to protect it, which greatly extend its service life. Protecting, increasing electrical insulation protection, is also a guarantee for users' safety. UV three -proof is a single -component ultraviolet curing electrical rubber. It can generally be cured with light (ultraviolet) and moisture (water in the air). Therefore. Why use dual solidification? Because in many applications, because the coated place is relatively narrow or obstructive, the light cannot be illuminated to the place, and the coatings where the light cannot be illuminated will be solidified by absorbing the trace water in the air to solidify the moisture solidification. UV three anti -paint is waterproof and shock resistance. The salt and fog resistance and breakdown intensity are stronger than other three anti -paint. In light curing, UV three-proof paint use UVLED curing lights with a wavelength of 365nm are generally used. The required light intensity is generally not high. It is generally about 400-800MW/CM2, 3-5 seconds of curing time for 3-5 seconds , Mainly noodle light sources. Tianhui's UVLED face light source adopts imported UVLED lamp beads, high -quality constant stream sources, and excellent heat dissipation design. It has the advantages of compact, high reliability, and high stability.

Nowadays, smartphones have exceeded the hundreds of millions of marks, and the cameras on smartphones are getting more and more powerful. The two cameras have almost belonged to the stage of elimination. In fact, in the production process of mobile phone cameras, UV glue is widely used. The CMOS components, plastic parts, lens, IR filters, etc. of the mobile phone camera need to use UV glue. So since it is useful to UV glue, it naturally needs Tianhui's UVLED curing machine. The mobile phone camera is more sensitive to warm rise. UVLED curing machines can curing 50-300 pieces at a time according to the size of the camera. UV glue is usually cured within 5-20 seconds. The external cooling system is small and exquisite in shape, which is very suitable for the production of common Taiwan methods. TIANHUI's LX-D40 and LX-C40 series light sources can be equipped with 4 or more different irradiation heads to meet different process needs. Some time ago, a company in Suzhou produced a camera module found Tianhui. Customers need to assemble the dialect lens to the sensor chip. At this time, glue solidification is needed. A long time ago, this process was used with traditional natural dry glue, but the time required was very long; later it was changed to a tube -type UV curing furnace, but the warm rise was too large, which affected the quality of the photosensitive chip. The customer has always been entangled with the issues of Wen Sheng and the right. Everyone must know that if the permeable lens fails to align with the sensitive chip, it is a bad product, and it is difficult to align. In response to the customer's situation, Tianhui set up a special discussion group. After some columns and communication, Tianhui provided customers with a perfect solution. Very satisfied, and then signed a long -term cooperation agreement with Tianhui. TIANHUI has obtained dual certification of national high -tech enterprises and Zhuhai high -tech enterprises.

1. AC -free LED is not the essential change of the device. In other words, there is actually no LED chip that does not have the working mechanism of AC Electric Farm. The AC -free LED that is now available is a specially arranged device in the internal chipset. It is just a change in the internal structure of the LED device. Of course The level of craft is not easy. The introduction of AC -free LED is mostly quoted information published by Seoul Semiconductor. It can be seen that it is a traditional rectifier bridge circuit to solve the problem of communication on the so -called DC LED power supply problem. It seems that the benefit is that the rectifier diode is eliminated, but the reverse resistance of LED is limited. When the grid is in a large peak, it is not necessarily the benefit. Because it is an imitation of the rectifier bridge circuit, only half of the current flows on the four bridge arm, and the DC load flows through the entire current, resulting in the current distribution of the upload of LEDs in each group. And light emitting efficiency, such as overcurrent to cause light decay and affect life. It is simple to solve. Just short -circuit the DC LED is removed. Take a closer look at the circuit, and now it has become positive and reverse LEDs in each group. In fact, you don't have to be too complicated at first. 2. AC -free LED does not avoid the essential constant current control technology. From the introduction, the light effect of AC LED is not higher enough than the usual LED. It is said to be the development stage. The author believes that the foundation of similar LED chips itself is the same. The main thing to restrict the amount of light per tile is the circuit type of the rectifier bridge. Imagine that only one group of LEDs can work normally, giving full play to the light effect, and 80%of the remaining four groups work in the underwriting state with poor light effects. No matter how to develop with it, it is naturally lower than that of ordinary LED's luminous efficiency. The way to improve is to abandon the unreasonable rectification bridge road. There is no constant current protection function in the AC -free LED. When used, it must be connected to the flow resistance. However, when the current at the limit of the power supply voltage is limited, it is necessary to work in the low light effect state of the underlying current when normal or low voltage. The resistance limit is a poor protection method. It not only has defects, but also rely on energy consumption to work, so that the utilization rate of power is reduced. If you want to add a PTC to solve the LED constant current problem, you don't know enough about the performance of the component. PTC is mainly used in overcurrent protection and thermal protection. When the current in the circuit is too large, when the PTC reaches the temperature of the residence after the heat, the resistance value rises sharply to the disconnection. The elimination circuit in the color TV uses it to generate a large current attenuation vapor. Demagnetic. When the PTC resistor is affected by the surrounding heat, the temperature will be opened when the temperature becomes more than the residential point, which can play a role in switching thermal protection. If you want to rely on the positive temperature coefficient characteristics of the PTC resistance to the LED's constant current protection effect: First, the PTC resistance passes the current, there is a heating time process to get hot. The current has already damaged LED. Second, the spontaneous heating temperature of the PTC resistor can really control the constant current. Then the impact of high environmental temperature and low may change dozens of degrees to make this "constant stream value" change meaningless. Is it possible that the common LED devices can also be so simple to flow at the current simple current? Unfortunately. And usually communication constant flow is more troublesome than DC constant current. In fact, there can be all kinds of high quality Product support. Instead of energy, LED manufacturers will be more energetic in terms of circuit technology, and it is better to focus on developing low -cost and high -light LED lighting products.

The UVLED curing system has a long life than mercury lamps, but there is still a certain life span. The life of the UVLED curing machine and the materials of the equipment are related to the time use. We take the product of Zhuhai Zhuhai Tianhua Electronic Co., as an example to briefly talk about the maintenance of UVLED curing machines. 1> Ensure that the working environment is clean and tidy, the temperature and humidity adaptation are used to prevent the equipment from moisture and leakage. 2> Wipe off the surface dust on the surface to prevent the inside of the UVLED device. 3> Keep the equipment in the air and the smooth outlet, prevent the heat emissions during work, cause the equipment to be damaged. 4> Check the light source of the light source every day, and confirm whether the lamp beads are not glowing. Whether the light beads luminous color are abnormal. If there is the above situation, replace the lamp beads in time. 5> Regularly measure the light power metering of the light power meter is abnormal.
