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. Substance. The built -in micro -treatment system can control the light intensity, adjust the lighting method, and realize the combination of light and art. 5. It is conducive to environmentally friendly LED as a full -solid luminous body, shock resistance, impact resistance is not easy to break, waste can be recycled, no pollution. The volume of the light source is small and can be combined at will. It is easy to develop into lightweight and short and short lighting products, which is also convenient for installation and maintenance. The above is the characteristics of COB integrated light sources. The LED light source features are analyzed in detail. I believe that the difference between these two lights also understands it.

Customers may be seeking to purchase ultra-violet (UVC) bulbs to sanitize surfaces in the house or other comparable locations given the current epidemic of Coronavirus Sickness 2019 (COVID-19) disease brought on by the new coronavirus SARS-CoV-2. 

What Is UV Light?

UV (ultraviolet) light is a form of electromagnetic radiation. It has a shorter wavelength than visible light, so it is invisible to the naked eye, but it can be detected by its effect on various substances. UV radiation can change chemical bonds in molecules, causing chemical reactions, and can also cause many substances to fluoresce or emit light. UV radiation degrades the chain structure of polymers, resulting in loss of strength and possibly discoloration and cracking. It is also absorbed by many pigments and dyes, causing them to change color. UV light  occur naturally in sunlight and can also be emitted by artificial light sources.

Types of UV Light?

• UVA, or near UV (315–400 nm), UVA light has the lowest energy. When you're in the sun, you're primarily exposed to UVA light. Exposure to UVA light has been linked to skin aging and damage.
• UVB, or middle UV (280–315 nm), UVB light is in the middle of the ultraviolet spectrum. A small fraction of sunlight contains UVB light. It is the main type of UV rays that cause sunburns and most skin cancers.
• UVC, or far UV (180–280 nm), UVC light has the most energy. Most of the UVC light from the sun is absorbed by the Earth's ozone, so you're not normally exposed to it every day. However, there are a variety of artificial UVC sources.

The lamp's wavelengths may impact how well it can inactivate viruses and the safety and health concerns that may be involved. Testing the lamp can reveal whether and how much of any additional wavelengths it emits.Typically, a relatively small wavelength range of radiation is emitted by LEDs. Since LEDs don't contain mercury, they have an advantage over low-pressure mercury lamps. 

At present, experiments prove that UVC light is the most effective type of ultraviolet light to kill bacteria. It can be used to disinfect surfaces, air and liquids. UVC light kills germs like viruses and bacteria by destroying molecules like nucleic acids and proteins. This makes it impossible for the bacteria to carry out the processes it needs to survive.

About UVC Light and the Novel Coronavirus

The novel coronavirus was tested in liquid cultures utilizing UVC light in a recent study published in the American Magazine of Infection Control.

UVC Light for Surface Sanitation

Another research reported in the AJIC examined using a particular UVC light to eradicate SARS-CoV-2 on lab surfaces. According to the study, the UVC radiation killed 99.7% of the live coronavirus in under 30 seconds.

Using UVC Light To Purify the Air 

A study that was investigated utilizing far-UVC light to eliminate two varieties of human coronaviruses inside this UVC air disinfection in the scientific journal Scientific Reports.

UVC Light for disinfecting liquids

 A recent study in the American Journal of Infection Control (AJIC) investigated the use of UVC light to kill large numbers of novel coronaviruses in liquid cultures. The study found that 9 minutes of UVC light irradiation can completely inactivate the virus.

How to Use UVC Lights to Kill Coronavirus

Water, air, and certain surfaces and spaces are difficult to clean. UVC lights can be used to disinfect these environments. For example, UVC lights and robots are used to disinfect water, surfaces in empty hospital rooms, and large vehicles such as buses. UVC lights  can be used in open spaces indoors to inactivate airborne viruses and other microorganisms. Lighting is installed at the top of the room at a height of at least 8 feet (2.4 meters). It is angled so that it shines horizontally or towards the ceiling rather than towards the floor. Fans and lights ensure that the air moves from the bottom of the room to the top and vice versa. By doing this, the entire air in the room is exposed to UVC lights , which inactivates airborne bacteria. UVC lights can also be installed in air ducts to inactivate airborne viruses and other bacteria that move from room to room.

It is important that UVC lights  used in rooms with people do not hit the room. His high intensity UVC light can damage eyes and skin in just seconds.

What Drawbacks Does UVC Lights Have? 

One of its drawbacks is that UVC light requires direct touch to be effective.

· It is yet unknown what UVC exposure parameters, such as wavelength and dosage, are most effective for killing SARS-CoV-2.

· Your eyes or skin may become damaged if exposed to particular UVC light kinds.

· The UVC light lamps that are offered for use at home are frequently of lesser intensity. As a result, the time it takes to destroy bacteria may be longer.

· UVC light sources might create ozone or mercury, which could harm people.

What Are The Many Lamp Kinds That May Emit UVC Radiation?

Here is a detail so know what will exactly work for you.

Low-Pressure Mercury Lamp:

 In the past, UVC radiation was most frequently produced by low-pressure mercury lamps, which emit mostly at 254 nm (>90%). This kind of bulb can also generate other wavelengths. Other lamps are available that generate not only visible and infrared light but also a wide variety of UV wavelengths.

Excimer Bulb or Far-UVC Lamp:

A particular type of lamp with a peak emissions of about 222 nm is called an "excimer lamp."

Pulse Xenon Lamps:

These lights, which produce brief bursts of UV, visible, and infrared light that have been controlled to release UVC radiation primarily, are occasionally used in hospitals to clean surfaces in operating theatres and other areas. These are typically used when there are no people present in the area.

Light-Emitting Diodes:

It is also getting easier to get LEDs that emit UV radiation. Typically, a relatively small wavelength range of radiation is emitted by LEDs. Since LEDs don't contain mercury, they have an advantage over low-pressure mercury lamps. LEDs may be more directed and have a smaller surface area.

UVC air disinfection has been incorporated into the standard cleaning procedures by many hospitals and medical institutions. Hospital wards, operating theaters, operating rooms and medical equipment benefit from UVC air disinfection to keep them clean and remove pathogens, including certain antibiotic-resistant superbugs. Daily cleaning can also use UVC lamps for disinfection.

LED lamp beads are already a very familiar product in the LED industry, but many people do nt know much about the price of LED lamp beads. What is the reason why LED lamp beads are very different? Everyone introduces factors affecting the price of LED lamp beads. 1. LED lamp bead brightness. The price of LEDs with different brightness is different. The price difference between ordinary brightness and high bright LED is very different. 2. The chip used by LED lamp beads. The chips include domestic and Zhuhai chips and imported chips (including American chips, Japanese chips, German chips, etc.). The chip is different, the price difference is very different. Currently more expensive American chips, followed by Japanese chips and German chips. The lower -priced Zhuhai chip has a slightly worse heat dissipation performance. 3. The effect of LED size on price. Different specifications of LEDs are different. For example, the price of 0603 LED lamp beads and 3528LED lamp beads is large; and the price of LEDs of 3528 and 5050 is different. Don't just pay attention to the price when buying LED lamp beads. Comprehensive assessment should. 4. LED installation. Divide resin packaging and silicone packaging. The price of resin packaging is cheaper. Others are the same. The cooling performance of silicone packaging is good, so the price is slightly more expensive than resin packaging. 5. LED lamp bead welding effect. The assembly and breakup of LED lamp beads, handmade welding and machine welding. Manual welding is to use the soldering iron and use the most primitive method for welding. The product that enters this operation is ugly (the welding joints are inconsistent with the size of the Fuzhou LED electronic display). The second is that the static maintenance measures are not good. Machine welding is welded with reflux welding, and machine welding is different. Not only the welding product is beautiful (the size of the welding joint, the smooth welding joints, the residual welding residue, the LED packaging is intact), and there will be no phenomenon of chip being burned by electrostatic and burning. At the same time, the LED position and direction are more beautiful. This can be seen directly from the appearance. 6. The consistency of the color of LED lamp beads. There are currently many packaging factories in China. There are thousands of large and small plus up, of course, there are strengths of strength and weakness. There are many small packaging factories because there is no split color division machine, so it is either different from the color or color, so it is difficult to guarantee the quality. The color consistency of the LED without splitting color is poor, and the effect after lighting on the LED lamp bead is not so good, of course, the price difference is relatively large. 7. Does the FPC have undergone environmental certification and UL certification? Is there any patent for LED?. No price is low. The price of certification and patent is more expensive. 8. FPC material. FPC division pressure dependent copper and copper applied copper. It is cheaper to apply copper plate, and it is more expensive. The pad of the copper plate is easy to fall off when the bend is bent, but the crushing copper will not. What kind of material is used to make decisions based on your own environmental environment to make decisions. 9. LED lamp bead color. Different color. Different price. Red and green are difficult to split color and color matching, so the price is higher than the price of other colors; the color of red, yellow, blue and other colors is easier and consistent. Therefore, the price is slightly cheaper. Special colors such as purple and brown due to color reasons, the price is the most expensive.

LED was born as early as the 1960s. In the 1980s, it was generally used on household appliances, such as audio volume indications, switching instructions, etc. In the 1990s, some new types of domestic car meters were also used to use LEDs, which were mainly used for charging instructions. Later, there were also showing engine speed conditions. When the driver stepped on the accelerator, LED lamps were lit from bottom to top. When the pine throttle, the LED lamps went out from top to bottom in order, which is quite eye -catching. In the mid -1990s, my country used LEDs to make high brake lights and installed on the car. Because the LED lights were fast, the car driver at the end of the tail could know the driving status of the vehicle in front, reducing the occurrence of a car rear -end collision accident. Classification of LED car lights: mainly divided into external lamps and internal lamps. Common lights are: front lights, turning lights, rear lights, fog lights, reversing rear lights, etc. Let's introduce the maintenance and use of each major light one by one. In general, as long as it is not on, it means that the bulb has been burned and must be replaced. But if it is not completely broken, it is just a decrease in brightness, red and dim light, and must not take it lightly. Because this may be a precursor of failure, and the reduced lighting ability is also a major reasons for the decrease in the major hidden dangers of safe driving. The most common is the astigmatism glass of the lamps or dust on the reflective mirror. At this time, the only thing that needs to be done is to remove the dirt with a velvet or lens paper. Another reason is that the battery charging capacity decreases, and the electricity is insufficient and the brightness is insufficient. In this case, you need to replace the new battery. There is also a possibility of aging line or too thin wires, causing the resistance to increase and affect power supply. This situation not only affects the work of the bulb, but even causes the line to pass through the heat and cause the fire. Various types of lamp maintenance methods: front lights: Generally speaking, friends who often drive night cars should consider replacing a pair of higher brightness front lights. In this way, in the dark night, enough brightness can help you see the road surface clearly on the road surface. All the details, and when you hit Yuanguang, you can also make you look farther. If the premise is permitted, you can even replace a pair of pyrine headlights (HID). The pyrine lamp not only has enough brightness and long life. It also has a feature: the color temperature is very high, and the color temperature close to the sunlight is also a protection of the driver's eyes. Tail light: Don't underestimate the rear lights. If the rear light is faulty, it is easy to cause a rear -end accident. Generally speaking, as long as it is not a failure, the tail lights have not been selected. In addition to installing transparent light shells to increase ornamental, it is a good choice to replace traditional light bulbs with LED luminous body. Traditional light bulbs have shortened, which means that after you step on the brake pedal, the LED brake light can be brighter earlier than ordinary light bulbs, so that the tail -to -vehicle has more preparation time. Fog lights: fog lights are often referred to as shooting lights. As the name implies, the main purpose of the fog lights is to ensure the driver's sight in harsh days, and to ensure that others can see you. Now there are many manufacturers. The quality of the choice of fog lights is relatively poor. Like the front light, in addition to changing the fog lights with enough brightness, choosing a pair of HID 氙 氙 fog lights is also a good choice. Receive lamp after reversing: It is a headache for reversing in the night, especially the driver with poor vision. The weak light of the original reversing light is actually not much help. At this time, you need a pair of backs to rear lights. This is an independent lamps installed in the middle or below of the rear bumper. It will automatically light up after you hang up the reverse gear. No longer need to worry about it. Technology Co., Ltd., specializes. In 13 years of LED component production and sales experience, ceramic 3535 lamp beads are used for flashlights and lights; use ASM, KS fully automatic solid crystal welding lines, Musashi point replenishment, from the choice of raw materials, He Line's gold thread, the gold thread of He Li's, Red copper brackets, San'an, Jingguan, Dehao Chip. 13 years of industry precipitation to escort your high -quality lamps.
