With the development of electronics technology, PCB lays a good foundation for a variety of electronic products, such as B. Development of PCB for LED lighting. A prime example is the development of the printed circuit board for LED lighting. The LED is soldered to the circuit board and has a chip that generates the light when electrically connected. A thermal heat sink and ceramic base are used to bond the chip.
It is difficult to cool an LED circuit board using traditional methods as it tends to generate a high volume of heat. SoCircuit boards with a metal coreare often chosen for LED applications due to their improved heat dissipation capabilities. Aluminum in particular is widely used to make circuit boards for LED lights. The aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate heat with much greater efficiency than a traditional rigid PCB.
What is LED circuit board?
LED is an acronym for Light Emitting Diode, i.e. semiconductor diodes. The LED is soldered to the circuit board and has a chip that produces the light as electrically connected. A thermal heat sink and ceramic base are used to bond the chip. Needless to say, LED circuit boards are at the heart of LED lighting, and an LED circuit board easily generates a high volume of heat, but is difficult to cool using traditional methods. Therefore, metal core circuit boards are widely used in LED applications due to their improved heat dissipation ability, especially aluminum is widely used to manufacture circuit boards for LED lights. In general, aluminum PCB contains a thin layer of thermally conductive dielectric material that can transfer and dissipate heat much more efficiently than a traditional rigid PCB.
Now SMD packaging style is the most widely used packaging style in LED applications. In general, it is limited to the light emitted by a single LED component. In other words, several LED components would be used for a single luminaire in order to achieve sufficient light. Like other semiconductor devices, PCB is the best method to electrically connect the LED components. And a circuit board with soldered LED components is usually called "LED circuit board".
The advantages of the LED circuit board
As the electronic products become smaller and thinner, the use of LED circuit boards is popular, and there are various advantages of using LED circuit boards as follows:
·Lightweight, low profile
·Low cost membrane switch with backlight
·Dust and moisture resistant
·Facilitate integration into complex interface assemblies
·Efficient low power consumption
·Available in a variety of sizes, colors and intensities
·May be used inSilver flex membrane switch and copper flexmembrane switch.
There are two main reasons that make the LED circuit board popular, in addition to increasing the light output of the fixture by integrating multiple LED components.
1. It is easy to match the color function by integrating the LED components with different color temperatures or different colors on the same circuit board.
2. It can reach the different lights to meet different lighting needs with the panels which have different shapes, sizes and materials.
The LED lighting industry
LED lighting or Light Emitting Diodes is an increasingly popular lighting solution, so it is popular to improve longevity and reduce environmental impact. There are some advantages of LED lighting over traditional methods as follows:
Low energy consumption:Great quality LED lights can be six to seven times more efficient than traditional incandescent bulbs. On average, switching your home from incandescent to LED lights can reduce your energy consumptionmore than 80 percent.
Longer Lifespan:LED light bulbs can last over 25,000 hours or three years of 24/7 operation, which is 25 times longer than any conventional light bulb. This saves you time, money and effort when buying and installing new lamps.
More efficient:Conventional light bulbs dissipate 90 percent or more of their energy as heat. LED lights reduce this by up to twenty percent. This means more energy is used to light your home and less to heat it unnecessarily.
Very compact:Due to their small size, LED lights have different sizes and types in applications. This means manufacturers can put LEDs in everything from computers and smartphones to cars and traffic lights.
Mercury Free:LED lights, unlike more traditional options, contain no mercury. SoLEDs have a lower environmental impact than traditional incandescent bulbs and are easier to dispose of without special disposal procedures.
The application of LED PCB
PCB LED lights have excellent energy efficiency, low cost and maximum design flexibility, allowing them to be integrated into numerous lighting applications.
Telecommunications:LED indicators and displays are always used in telecommunications equipment because of the surrounding machinery and have great heat transfer ability. Therefore, aluminum-based LED PCBs have a beneficial impact on their application.
Car:Aluminum PCB LEDs are also used for automobiles on turn signals, brake lights and headlights and other applications. There are a few factors that make aluminum PCBs ideal for the automotive industry such as: B. the durability and competitive prices.
Computer:LED indicators and displays are becoming increasingly popular in computer applications. Andaluminum circuit boardLEDs are an ideal solution due to the heat sensitivity of computer machines. Aside from LED applications, aluminum circuit boards are also used for computer parts such as power devices and CPU boards due to their ability to dissipate and transfer heat.
Medical:Lighting tools used in surgeries and medical examinations commonly use high-power LED lights, and these LED lights often use aluminum circuit boards, which is mainly due to the durability and heat transfer ability of aluminum circuit board LEDs - this ensures that medical devices function properly regardless of the number of patients cycling through a doctor's office. For lighting tools, expect medical scanning technology to also commonly use aluminum circuit boards.
SMD LEDs in your circuit board
There are many devices, including LEDs on a printed circuit board, that use surface mount components. If the wires are fairly thin, through hole components can easily bend, making it look cheap from the outside. If it is correct to solder the SMD LED it will be rigid on the board. In addition, the SMD LED can also be placed behind a screen, and cheaper LEDs that use an incandescent bulb protrude through the packaging. So the SMD LED can be placed behind a small screen in your package to be cleaner for your device. As you know, many PCBs that contain LEDs are made with multilayer FR-4 substrates, so you need to have a pattern of closely spaced filled or plated vias under each component so that it can transfer heat and get to you power and soil layers.
If your LEDs have a small footprint and are surface mount, they can use our vias. There will likely be a weak solder joint or even tombstone formation as it does not fill or coat the vias and then solder can penetrate the vias during assembly. The reason why it is better to use only SMD LEDs on an LED lighting array is because of the problem with wicking. A single LED with decent power output will not cause damage to your board due to excessive heat. However, if you have a system for lighting applications, it must suffer from massive heat for the board that carries your LEDs, making it difficult to cool using traditional board methods. Because the individual LEDs are too small, there's really nowhere to put a heatsink, and a heatsink will block the emitted light anyway. Due to the large thermal requirements, the metal core boards are typically used in LED lighting applications due to their ability to dissipate a lot of heat. In general, aluminum is used for LED lighting applications as a metal core in printed circuit boards. In addition, aluminum is the metal most commonly used as a core among all possible metal core PCBs. In addition to copper, iron is also used for metal-core printed circuit boards.
