Description

What is led aluminum pcb?

As printed circuit board technology has continued to evolve, it has paved the way for the creation of a host of exciting product innovations.

A prime example is the development of the PCB for LED lighting.

The LED is soldered to the circuit board and features a chip that produces the light when electrically connected.

A thermal heat sink and a ceramic base are used to bond the chip.

PCB LED Applications

An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.

Consequently, metal core PCBs are frequently chosen for LED application due to their enhanced ability to dissipate heat. Aluminum in particular is

often used to manufacture circuit boards for LED lights.

The aluminum PCB typically includes a thin layer of thermally conductive dielectric material that can transfer and dissipate the heat with much

greater efficiency than a traditional rigid PCB.

PCB LED Applications:PCB LED lights can be incorporated into numerous lighting applications due to their combination of excellent energy

efficiency, low cost and maximum design flexibility. Examples include Automotive headlights, Airport runway landing lights, Lighting used in military

field applications, Street lighting, Highway tunnel lighting, Photovoltaic (solar) lighting, Flashlights and lanterns, Traffic and signal lighting, Lighting

in hospital operating rooms, High growth plant lighting and many others.

Features of LED  PCB

Mong all Metal core PCBs (aka MCPCBs, known for their ability to provide effective thermal dissipation for electronic products), Aluminum PCBs is

the most common type – the base material consists of aluminum core with standard FR4.

It features a thermal clad layer that dissipates heat in a highly efficient manner, while cooling components and increasing the overall performance of

the products.

Currently,Aluminum Backed PCBs is regarded as the solution to high power and tight tolerance applications.

LED is an abbreviation for light-emitting diode. An LED is essentially a two-lead semiconductor device that emits light when current passes in a

certain direction.

Although LEDs start with devices that only emit low-intensity infrared light, this technology has been widely used in lighting for many years.

Modern LEDs not only provide high intensity, very bright light but also different uses and use in different scenes, such as plant growth lights, car

lights, street lights, traffic lights, shadowless lights in hospital operating rooms.

The advantages of LED PCB

With the electronic products is more and more smaller and thinner, making it popular to use LED PCB, and there are various advantages with using

LED PCB as follows:
·Lightweight, low profile

·dimensional?stability?

·thermal?expansion?

·heat?dissipation

·Lower cost backlit membrane switch

·Dust and moisture resistant

·Make it easy to integrate into complex interface assemblies

·Efficient low power consumption

·Available in a wide variety of sizes, colors, and intensities

LED components

There are two main reasons which make the LED PCB be popular in addition to increasing the light output of the fixture with integrating multiple

LED components.

1.It’s easy to tune the color function by integrating the LED components with different color temperatures or different colors into the same PCB.

2.It can achieve the various light fixtures to meet different lighting requirements with the boards that have different shapes, sizes and materials.

Benefits of LED lighting PCB

LED lighting or light emitting diode is an increasingly popular lighting solution, so it’s popular to improve longevity and reduce environmental

impact. There are some benefits of LED lighting for traditional methods as follows:

Lower power consumption:

great LED lights with high quality can be six to seven times more efficient than traditional incandescent lights.

On average, switching your home from incandescent lighting to LED lights can cut your energy use by?more than 80 percent.

Longer Lifespan:

LED light bulbs can have a life of over 25,000 hours, or three years of 24/7 use, which is 25 times longer than any traditional light bulb. So it saves you the time, money and effort involved in purchasing and installing new bulbs.

More Efficient:

Traditional incandescent light bulbs release 90 percent or more of their energy as heat.

LED lights cut this by up to twenty percent.It means more of your energy is going into lighting your home, and less into unnecessarily heating it.

Aluminium PCB Stack Up details as the drawing.

1. Aluminium PCB Copper Traces Layer

The copper circuit (traces) layer is etched to form the printed circuit, Compared to FR4 material,Aluminium PCB can bear higher electric current

when same thick circuit layer and same trace width.

2. Aluminium PCB Dielectic Layer

The dielectic layer is the core technology of the Aluminium PCB, which mainly serves as the function of adhesion, insulation and heat conduction.

The better the thermal conductivity of insulation is, the quicker the components spread the heat when they work, which can realize the purpose like

improving power loading of the modules,reducing volume, extending life span and increase the output power.

3. Aluminium PCB Metal Substrate Layer

Usually, considering the cost and technical characteristic, aluminium is the ideal choice. The available aluminum plates are 6061,5052,1060 etc.

If there is a higher heat transfer performance, mechanical properties, electrical properties and other special performance requirements, copper,

stainless steel plate, iron plate, silicon steel plate, etc can also be used.
