Compared with small -power LED lamp beads, high -power LED lamp beads, higher power, brighter brightness, and higher price. The rated current of small power LED lamp beads is often 20mA, and the rated current can basically be counted as high power. Common power files are: 0.25W, 0.5W, 1W, 3W, 5W, 8W, 10W, etc. The brightness unit is LM (lumen), and the brightness unit of small power is generally MCD (millaka, 1cd = 1000mcd), which is also the Lighting intensity I. The high -power lamp beads are mainly imitation bright lamp beads, as shown in the figure below. During the application process of high -power LED products and devices, heat dissipation, electrostatic protection, and welding have a great impact on their characteristics. Zhuhai manufacturers specialize in the production of high -power LED lamp beads, small -power LED lamp beads, manufacturers mass production, affordable price! 1. Due to the limitations of semiconductor light -emitting diode chip technology, the conversion efficiency of LED needs to be improved, especially high -power LEDs. Due to its high power, a large part of the electric energy can be transformed into heat energy release (with the development of semiconductor technology, conversion conversion Efficiency is gradually increasing), which requires end customers to do a good job of heat dissipation when applying high -power LED products to ensure that the normal work of high -power LED products work. 1. The heat sink requires that if the finished sealing requirement is not high, it can directly flow with the external air environment. The manufacturer recommends that the aluminum or copper heat sink with fins with fins can be used. 2. Effective heat dissipation surface area for 1W high -power LED white light (other colors are basically the same), and manufacturers recommend the sum of the effective heat dissipation surface area of the heat dissipation tablet≥50-60 square meters; for 3W products, it is recommended to take valid heat dissipation surface area for 3W products≥150 square meters; higher power depending on the situation and test results, try to ensure that the temperature of the heat sink does not exceed 60 C. 3. When the connection method is connected to the high -power LED substrate to ensure that its contact surface is flat and good contact. In order to strengthen the degree of combination of the two contact surfaces, the manufacturer recommends that the thermal silicon grease is applied at the bottom of the LED substrate or the surface of the heat sink (heating silicone grease grease in thermal conductivity. Thermal Conductivity≥3.0W/m.k), thermal silicon grease requires a uniform and appropriate amount, and then fix it with screws. Second, electrostatic protection LED is a semiconductor device, which is more sensitive to static electricity, especially for white, green, blue, and purple LEDs. 1. The generation of static electricity friction: In daily life, after the contact of any two different materials of objects is separated, it can generate static electricity. The most common way to generate static electricity is to friction of raw electricity. The better the insulation of the material, the easier it is to rub the electricity. In addition, if any two different types of objects are separated after contact, it can also generate static electricity. Induction: For conductive materials, because electrons can flow freely on its surface, if it is placed in a electric field, due to the same sex, the opposite sex is sucking, positive and negative ions will be transferred, and the charge will generate charge on its surface. Transmission: For conductive materials, because electrons can flow freely on its surface, such as contact with the electrical body, charge will be transferred. 2. The harm of static electricity to LED Due to the heat generated by the instantaneous electric field or current, the LED local injuries are injured. Due to the insulation layer of the electric field or current destroying the LED, the device cannot work (completely damaged), which is manifested as a dead lamp. 3静电防护及消除措施对于整个工序生产测试包装等所有与LED直接接触的员工都要做好防止和消除静电措施厂家分析6点主要有1车间铺设防静电地板并Do a good job. 2. The workbench is the anti -static workbench, the production machine is well grounded. 3. Operators wear anti -static uniforms, with anti -static bracelets, gloves or footsteps. 4. Apply ionic fan. 5. Welded electric iron for grounding measures. 6. Packaging uses anti -static materials. 3. Welding points 1. Select the constant temperature soldering iron when welding. The welding temperature is below 260 C. 2. If the high -power LED encapsulated by silicone, the maximum heat resistance temperature of silicone is 180 C. Therefore, the welding temperature of LED must not exceed 170 C. The time does not exceed 3S. Fourth, advantages analysis 1. Less power consumption: LED with a light -emitting effect of 75LM/W is greatly reduced than incandescent lights with the same brightness. 2. Long life: the product life is as long as 50,000 hours, and it can be lit for 5 years in 24 hours. 3.

Most of the domestic UV lamp tubes are mercury lamps, and the shell material is quartz glass. One of the better features of this glass is to transmit ultraviolet rays and infrared rays. However, because the quartz glass is very thin, it is only 0.3mm, so it is not significant for the unique effect on infrared rays. The UV lamp tube is launched at the time of working, that is, infrared, visible light, and ultraviolet rays exist at the same time. Because infrared rays have a strong heat effect, this has led to a dramatic temperature increase in the UV area. It is simply relying on thick quartz glass to ensure that the temperature effect of the UV area is not good. Once a domestic manufacturer, a domestic manufacturer specially purchased a quartz glass cover and installed it on the UV lamp tube. In order to effectively avoid the middle layer too thick, or on the other hand, effectively reduce infrared rays and reduce calories, the following points must be achieved: first to ensure the efficacy of the cooling section, it needs to be transferred to the dedicated wind supply and air supply device to the cooling section. , So that it can exude the heat in time to ensure that the product is cured at a lower temperature for UV. The best state is that the product UV can be reduced to less than 40 degrees before. The second is to ensure that the UV section has a smooth exhaust system. Each UV lamp tube is installed with pumping pipes, because the UV lamp tube is the largest heat source during normal working. At the same time, in order not to cause the wire body airflow to disordinate, the air volume should be supplemented at the same time, so it is necessary to arrange the air supply device. The more common approach is to arrange a exhaust link UV lamp tube on the top of the online body, and a row of winds is also arranged below the side of the thread, on the one hand, it is to maintain the cleanliness of the UV room. Get off at the top of the online body. At this time, the natural wind without heating is used to help cool down the overheated area in time. Furthermore, using UVLED light sources as a luminous body, UVLED light source is a pure ultraviolet light source. During the work process, infrared rays, visible light and other miscellaneous light are largely reduced. It is a single band of ultraviolet light emitting a single band of ultraviolet light. Although the total electrical power does not have high mercury lamps (the light in different bands is up, high power consumption), the single wave length is only one -tenth or less of the UVLED light source. Therefore, the UVLED light source, while reducing the calories and improving energy, is an irreplaceable ultraviolet light solid -curing light source.

TIANHUI has also made a lot of UVLED furnaces and has rich experience. So what are the main application directions for the UVLED curing furnace? UVLED CITC has been widely used in the fields of 3C electronics, medical devices, accessories and other fields. Many manufacturers have replaced the original UV mercury lamp production line to UVLED curing furnace production line. As a UVLED furnace producer, what are the application directions of the UVLED furnace today? 1. Spraying: Most of the plastic spraying companies such as the general mobile phone case, cosmetics shell, small appliance shell and other plastic spray companies can be used. The UVLED curing furnace is required on the mobile phone case spraying and UV printing. 2. Medical aspects: There are also many places to use UV glue in the medical device industry, especially like syringa needles, infusion pipes, oxygen masks, cardiovascular brackets, dentistry, etc., because many high requirements have high requirements for light pollution, so tianhui production The UVLED UV light source curing equipment is particularly suitable for this process. 3.3C: There are many 3C products, such as mobile phone chargers, data cables, headphones and other products. In the production process, UV glue needs to be used for bonding, coating and sealing. UV glue can be cured instantly after the UVLED ultraviolet curing machine irradiation. It can no longer be settled for a long time as before before it can be determined. The above is only a few typical cases. In fact, as long as the process of UV glue is used, it is all necessary to support ultraviolet UVLED solid light source machines. If it is a small part and a small number of UVLED furnaces that can be produced in Tianhui, you only need to set the irradiation time, the irradiation power, and the irradiation distance. And compared to the equipment of the previous mercury lamp, the size is smaller, the energy consumption is lower, and the efficiency is higher.

From factory enterprises to resident families, the detection and monitoring of alcohol leakage and monitoring of drunk driving are very important and essential for the personal and property of the residents. Today, due to the enhancement of people's awareness of safety and the improvement of environmental safety and life comfort, coupled with the development of gas sensors towards low power consumption, multifunctional, and integrated direction, alcohol concentration LED detector is very broad Real market and potential market requirements. The functional characteristics of the alcohol concentration LED detector are: 1. Professional airway design, test results of human exhaust alcohol content 2. Accurate measurement results, three -grade alcohol concentration content prompt, LED light visual display: Safe (green): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low): Low low: Low low) In 0.02% BAC (0.10mg/L Brac) Warning (yellow light): 0.02% BAC (0.10mg/L Brac) to 0.05% BAC (0.25mg/L Brac) Danger (red light): higher than 0.05% BAC (0.25mg/L BRAC) 3. Short warm -up time, no more than 10 seconds 4. Fast response and recovery of alcohol concentration LED detector with voice alarm, LED display gas alcohol concentration and environmental temperature value, alcohol concentration value and environment The temperature value automatic circulation display. The alcohol concentration LED detector can set the different alarm thresholds of alcohol concentration and environmental temperature according to different environments, that is, to exceed the alcohol concentration value or the ambient temperature threshold for a live -action voice alarm, indicating the harm to the harm. According to a report from the World Health Organization, when the driver's blood content in the blood reaches 80mg/100ml, that is, when the critical value of drunk driving, the opportunity to occur in traffic accidents is 2.5 times when the blood is not alcohol in the blood. The alcohol content in the blood is 100mg/100ml. The chance of a traffic accident is 4.7 times when the blood does not contain alcohol. Therefore, in order to reduce the occurrence of accidents, alcohol concentration LED detection is necessary. Alcohol concentration LED detection is characterized by simple hardware structure, efficient software design and high cost performance. It can be used for winery, food fermentation factories, alcohol warehouses and traffic security inspection. UVLED has certain market prospects and practical value. The matters that the alcohol concentration LED detector needs attention during the test: 1. Test it after drinking at least 20 minutes, because the alcohol takes about 20 minutes from the digestive system to the blood. Test it immediately after drinking, and the result can only reflect the alcohol concentration in the mouth at that time, not the alcohol concentration contained in the blood. 2. In order to make the test results accurately, please wait for 20 minutes after drinking. 3. Do not directly wipe the products with chemicals or corrosive solutions to avoid liquid flowing into the air -blowing pipe. 4. If the product will not work normally in a high -concentration gas environment. If there are too many high -concentration gases in the product, the product will not work normally. Please blew the residue gas in the product or throw the product more or more, or wait a few more before testing. 5. It is strictly forbidden to place and use in a closed environment with corrosive gases or air pollution in pigments, pesticides, alcohols, etc.
