COB integrated light source and LED light sources are two kinds of lamps that are famous in today's lamp industry. The difference is that LED integrated light sources generally use large -size high -power LED chips with a large size of more than 1 watt. The COB light source is mainly based on a small -power LED chip of less than 1 watt, and a small amount of COB light source will also use a high -power LED chip of more than 1 watt. Their overall characteristics have some similarities, and the manufacturers make a detailed analysis for everyone. COB integrated light source characteristics to integrate several small power LED light sources on a stand to get light sources to integrate light sources. Generally referring to the form of encapsulation of Chip on Board, which is commonly known as COB packaging, that is, to put several chips directly to the substrate, encapsulate with silicone, epoxy resin or other materials. The yellow is fluorescent powder. At present The main problem in lighting applications is the problem of volatile fluorescent powder and the aging of the lens. COB integrated light sources are widely used in LED bubbles, LED light cups, LED spotlights, LED downlights, LED ceiling lamps, LED bean bile lamp products. It is one of the mainstream trends of LED lighting light sources .cob integrated light sources mainly have the following Features: 1. Can be freely matched and combined to form a variety of LED lamps, which is convenient for assembly. 2. High reliability, no dead lamp, no plaques. 3, uniform light, soft light, no glare, not hurting the eyes. 4. High color rendering index, high light effect. 5. Under normal current, the minimum attenuation is controlled at less than 3% within 1000H. 6. Safe and reliable, all work below 50V, fully consider the application certification. 7, green environmental protection, no pollution. LED, high -efficiency energy -saving effect, has been given the title of green lighting. According to the analysis of LED lighting products, COB integrated light sources, as the core of lighting, have always been the core of LED development. The understanding of COB integrated light sources can be divided into several aspects. Click, then place the silicon wafer directly on the surface of the base, heat it to firmly fix the silicon wafer until the base is firmly fixed, and then use the silk welding method to directly establish electrical connections between the silicon wafer and the base. Compared with the traditional aluminum substrate, ceramics, ceramics The reflectance of the substrate is high, which helps improve the light effect. Ceramics has the characteristics of high reliability, long life and other characteristics. The thermal expansion and contraction coefficient of ceramics is small. Even in high temperature environments, the surface is relatively flat, which helps heat dissipation. It is easy to assemble, you can directly assemble the ceramic substrate COB light source directly on the radiator through the heat conduction. The heating coefficient of ceramics is high, LED has the industry's leading thermal streaming maintenance rate (95%), and ceramics is an insulator. It helps LED lighting products to pass various high -voltage tests and can resist high pressure 4000V or more. Choose LED lamp beads to choose the right high -quality LED manufacturer. The material is guaranteed, and the price of large amounts will be relatively favorable. There is no middleman to earn the difference. Xiaobian recommends the Zhuhai manufacturer LED light source and COB integrated light source. Rest assured LED manufacturers are trustworthy! LED light source characteristics LED light source is the light source of luminous diode (LED), which has the characteristics of high efficiency and long life. LED light sources mainly include ring light sources, strip light sources, line -type light sources, refusal light sources, backlight sources, outer coaxial reflection light sources, internal coaxial dot -shaped light sources, hemispherical ridge light sources, etc. With the continuous research of people's research on semiconductor luminous materials, the continuous progress of the LED manufacturing process and the development and application of new materials (nitride crystals and fluorescent powder), the ultra -high brightness LEDs of various colors have made breakthrough progress, and their luminescence is emitted The efficiency has improved a lot, and all the color of the visible light wave segment has been realized in terms of color. The important thing is the appearance of ultra -high brightness white light LED, making the LED application field span into high efficiency lighting light sources market. Someone once pointed out that high brightness LED will be one of the great inventions after the invention of human beings invented the invention of the fixing light bulbs. 1. High emitting efficiency, LED has improved its luminous efficiency after decades of technical improvement. And its light monochromaticity and narrow spectral spectrum, no filter can emit a colored visible light directly. 2. Less power consumption. 3. Life life, use electronic light field radiation, filament light and easy to burn, heat sink, light attenuation and other disadvantages. The size of LED lights is small, light weight, and epoxy resin packaging can withstand high -intensity mechanical impact and vibration, not easy to break. 4. Strong safety and reliability, low heat, no heat radiation, cold light sources, can be safely touched: can accurately control the light and luminous angles, soft color, no glare; no mercury, sodium elements, etc. may endanger health and health.

At present, the use of UVLED light sources is very wide, and one of the most obvious features of UVLED curing light sources is that the thermal effect is low and no radiation. It is precisely because the thermal effect of UVLED facial light source is low. Below I will use a label printing technology to be more sensitive to calories to explain it. The thermal contraction membrane label is a thin film label printed on the plastic film or plastic tube with a dedicated ink. During the label, when heating (about 70 C) Contraction, close to the surface of the container, the thermal contraction membrane label mainly includes a shrinking sleeve label and contraction surround label. The shrinking sleeve tag is based on the heat -shrink film as a substrate. The cylindrical tag made by printing after printing. It has the characteristics of convenient use and is very suitable for alien container. The thermal shrinking film label is part of the label market. It is currently in rapid growth. The market share is expanding. It is expected that the annual growth rate is about 15%, which greatly exceeds the annual growth rate of about 5%of the ordinary label market. Become a highlight of the label printing industry, predicting that the domestic hot film market will grow at a rate of more than 20%within 5 years. The production of thermal contraction label has high technical requirements for technology. For ordinary water -based and solvent -type inks, the drying temperature is too high, then the material occurs in heat contraction; if the temperature is too low, the ink is not completely dry enough. Therefore, The crafts are quite complicated, and the waste rate is high. For UVLED face light sources, in the action of ultraviolet energy, the ink enables polymer substances to form a mesh crosslinker in an instant, the ink is quickly solidified, and the temperature of the printing material has no effect. Therefore, the UV optical curing technology fundamentally solves the problem of the heat shrinking film label fear of heat. UVLED optical curing technology is dry to print ink, and the pure ultraviolet drying rarely generates any heat, and there are many benefits to our environment.

The LED integrated light source is different from the COB light source: 1. Different LED chips used for LED chips generally use large size high -power LED chips with a large size of more than 1 watt. The COB light source is mainly based on a small -power LED chip of less than 1 watt, and a small amount of COB light source will also use a high -power LED chip of more than 1 watt. 2. Different supports used by LEDs are only 10W, 100W, 500W and other square brackets. The materials are mainly copper, and the brackets have 2 side feet. There are many sizes used in the COB light source. Its shapes are square, rectangular, oval and other dozens of stents. The materials are mainly aluminum, and there are copper and ceramic brackets. Generally, they are generally all. Not to bring. 3. Different LED integrated light sources in the use of light sources is to make outdoor lamps such as LED light lamps, LED street lights, etc., and its maximum datches can reach 500W. The COB light source is mainly used on the indoor lamps such as LED downlights, rail lights, ceiling lights and other indoor lamps. Extended information: COB integrated light sources are widely used for LED ball bubbles, LED light cups, LED spotlights, LED downlights, LED ceiling lamps, LED bean bile lamp products. They are one of the mainstream trends of LED lighting light sources. LED lights are light -emitting diode. They use solid semiconductor chips as luminous materials. Compared with traditional lamps, LED lights are energy -saving, environmentally friendly, color rendering and response speed. 1. Energy -saving is the most prominent feature of LED lights. In terms of energy consumption, the energy consumption of LED lights is one -tenth of incandescent lamps, and a quarter of energy -saving lamps. This is one of the biggest features of LED lights. People now advocate energy conservation and environmental protection. It is precisely because of the characteristics of energy saving that the application range of LED lights is very wide, which makes the LED lights very popular. 2. If you can work on the high -speed switch status, we usually walk on the road, and you will find that the screen or screen of each LED is unpredictable. This shows that LED lights can be done at high speed switches. However, for the incandescent lamps we usually use. When living in normal times, if the number of switches is too large, it will directly lead to the broken incandescent lamp. This is also an important reason for the popular LED lamp. 3. Environmental protection LED light does not contain any heavy metal materials such as mercury, but incandescent lamps are contained, which reflects the characteristics of LED light environmental protection. People now attach great importance to environmental protection, so more people are willing to choose environmentally friendly LED lights.

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. Zhuhai Tianhui Electronic Co., LTD. is a company engaged in LEDUV irradiation equipment. After years of accumulation, it has a very rich LEDUV irradiation point light source and wire surface light source equipment types. It can also customize various equipment according to customer needs according to customer needs.

With the advent of UV LEDs, UVLED technology began to gradually apply in various industries, UV LED curing technology has brought about changes in PCB exposure, because there are many advantages such as low energy consumption, high performance, environmental protection, etc. UV LEDs, UV LED Technology is applied to the field of PCB exposure. In PCB exposure, the light source characteristics of the exposure light directly affect the quality of the exposure and the effect of exposure. The application of UV LED in PCB exposure is mainly to use ultraviolet exposure Ultraviolet light reacts to the sensor -sensitive dry film to generate reaction. The energy consumption of traditional lamps in PCB exposure is very high, and the service life is very short, only 800 hours, and the lamp tube needs to be preheated before each use. The actual effective working time of the PCB exposure tube is less than 800 Hour. The traditional mercury lamp will produce a lot of heat and infrared rays during the use of glowing, and it is easy to destroy the coating, so there is a certain distance in the process of use, so as to reduce the efficiency of its use efficiency. The application of UV LED in PCB exposure, compared with traditional mercury lamps, has the advantages of high luminescence, long life, and low energy consumption, which has greatly interested in domestic and foreign exposure machine manufacturers and make them develop and develop them. Taking advantage of the new UV LED technology. Although the light power of a single UV LED is not high, in practical applications, its light sources can achieve very high ultraviolet light intensity through special optical treatment and structural combination. It can be used in PCB exposure. The use of scanning exposure methods can effectively reduce the size area of the UV LED light source, and then solve the heat dissipation problem of UV LED. The application of UV LED in PCB exposure has many advantages such as uniform distribution, stability, and decrease in equipment costs, and the performance of various performances is higher than the traditional exposure process, so it can meet the PCB exposure process.
