Especially, the base material is essential for the PCB to determine how they transfer heat effectively. In some applications, specific properties are required in their PCBs. It is right in the case of temperature-sensitive products.
In response to growing interest in the cost-effective and highly efficient lighting method, the LED lighting business is rapidly expanding. An LED is a semiconductor diode and lies in the category of electroluminescent luminaries.
The electroluminescent generate light by recombining charge-carrier pairs in the semiconductors with a suitable energy gap. They offer the right edge in customer service because of low operating power and voltage, stability, extended lifetime, and compact sizes.
There are several types of Led lights in the market with different design shapes. With high thermal dissipation, LEDs generate light, which is their most appealing feature, so they are safe for daily use.
The main reason that LEDs lights are embedded in the PCBs is its characteristics. The LEDs are efficient and dependable to use in PCB applications. LED PCBs often have blue or white color as single or bi-color LEDs.
LED PCBs prototype usually works as the light indicator in the non-tactile membrane switches. They are used frequently under rubber keypads and polyester graphics, as well. Right now, the core of LED lightening is LED PCB.
In LED PCB manufacturing, the LED is attached to the circuit board with the help of soldering and has a chip that is used to produce light when connected to the electricity. A ceramic base and thermal heat sink are used for chip bonding.
An LED circuit board is likely to generate much heat, and using traditional cooling methods makes it difficult to cool it. The aluminum PCBs are preferred for LED applications as they offer a high ability to thermal dissipation.
PCBs are often found in the membrane switch for lower circuits with LED indicators because they give structural display window. These can integrate easily into the membrane switch design of PCB, but when it comes to choosing the LED type, there are some choices to make.
It is beneficial to use LED PCB as the electronics get thinner and smaller. Also, they offer a simple manufacturing, final assembly, product sourcing, and less quote. The benefits of LED make PCB LED lighting much desirable by the customer for numerous applications.
Other application fields of LED PCB board are airport runway lights, street lighting, photovoltaic (solar) lightening, lanterns and flashlights, highway tunnel lightening, highway growth plant, signal, and traffic lighting.
These LED lights are suited best for consumer devices, some marine and aviation applications, flashlight and other camping accessories, lower-light environments, elevator lighting, power converters, decorative and concealed lights, and many more.
When the LEDs are embed in the PCB, it then becomes easier to assemble the membrane switch with touch screens, keypads, and other membrane switch types. The LED PCBs have more design freedom, even creating backlit switch assemblies with intricate designs.
The thinness of the LED PCB membrane switches helps to minimize the overall footprints of complex interfaces of a switch. Engineers and designers, when upgrade and revise products they often choose LED PCBs.
LED PCBs offer the best affordable backlighting for different types of membrane switches. Sometimes, they are the best backlighting choice for small symbols and icons because backlighting large symbols and icons are not easy to achieve compared to LED PCB.
1. LED aluminum PCB
LED aluminum PCB has good conductivity, so it is widely used in the LED PCB industry. Led aluminum PCB also is known as LED PCB aluminum, it in the LED PCB circuit design or in the thermal conductivity and reflective performance of the test has a very good performance. Led aluminum-based circuit board also has good cooling and heat dissipation performance, which can also be very good to extend the service life of Led products.
2. LED Strip
LED lamp strips are generally divided into two types: LED flex lamp strips(LED flexible PCB or LED flex PCB) and LED rigid lamp strips （Rigid PCB
A、The flexible LED light strip adopts FPC as the printed circuit board assembly, and USES the patch LED to assemble, so that the thickness of the product is only the thickness of a coin and saving space; The general specifications are 30cm long (18 LED, 24 LED) and 50cm long (15 LED, 24 LED, 30 LED). There are also 60cm, 80cm, etc. Different users have different specifications. And it can be cut at will or extended at will without being affected. The FPC material is soft and can bend, fold and wind at will. It can move and stretch freely in 3d space without breaking. Suitable for the use of irregular places and narrow space, because it can be arbitrary bending and winding, suitable for advertising decoration in any combination of all kinds of patterns.
B、LED rigid light strip is made of rigid PCB board to assemble the circuit board, LED can be assembled by patch LED, or directly inserted LED, depending on the needs of different components. The advantage of a rigid light strip is that it is easy to fix, convenient to process and install. The disadvantage is not free bending, not suitable for irregular places. There are 18 LED, 24 LED, 30 LED, 36 LED, 40 LED and other many specifications assembled with the patch. There are 18, 24, 36, 48 and other different specifications assembled with directly inserted led. In addition, in addition to the front of the installation of LED is also installed in the side, side light also known as the Great Wall light strips.
3. led display PCB board
LED display is a flat panel display, composed of many small LED module panels, used to display text, images, video, video signal, and other information devices. From the earliest P31.25 outdoor screen to the current P1.58 indoor screen, the led display PCB board used in it is more and more sophisticated, and the led PCB board design and production level are more and more excellent. For example, P1.58 led display PCB board, the designed pad size is the only 0.15mm, and this board is a second-order HDI board. The following figure is P1.58 board produced by PCBONLINE.
In addition, we are still constantly studying the modified display screen, such as the latest glass display screen, which can be transparent when viewed from the inside and the display screen when viewed from the outside.
