What Is LED Thermal Management?

The term LED means Light Emitting Diode and is perhaps one of the biggest sensations in the world of lighting.

LED based on the nature of its functioning has many inherent advantages.
It has significantly smaller footprint, higher efficiencies and lasts a long time.

It therefore goes without saying that with the rising popularity of the LEDs, the challenges of designing with them is growing, especially in areas of LED thermal management.

In this context one of the best places to start with would be thermal management within a printed circuit board or MCPCB.

Thermal Management In MCPCB

If you are using LED power, there are chances that you would encounter problem at or above 80 watts.

For example if you are considering application like the street lighting which might require up to 150 watts per lamp, led thermal resistance at such high power point would be a cardinal concern.

The point to remember is here would be that thermal connection between the LED and the MCPCB is established with a help of a thermal via and designing them at varied planes could reduce the overall system temperature by 10°C.

Not just that research has indicated to achieve the right kind thermal management, MCPCBs can be created using a wide range of heat-dissipating materials without changing the LED component.

From copper which offers better thermal conductivity to aluminum which is cheaper to specialized MCPCBs using coated steel, ceramics or many other options, the range is unbelievably long.

To address the LED thermal resistance issues and achieve optimum thermal management using LED, external heat sinks can also be used.

Conclusion: Digital Control

One fundamental approach to address the LED thermal resistance issue and effective thermal management via LED can be achieved through relying on digital control.

One brilliant example of that could be the use of thermistor near the LED.

This will enable tracking temperature in a specific part of the MCPCB that is mounting the LED.

As a result this will not just monitor temperature but can also incrementally cut down voltage supply of the temperature exceeds a given limit.

Moreover digital control can also optimize LED efficiency and thereby the overall energy usage and effective thermal management.

Thermal Management Of MCPCB

Thermal management is important for the electronic systems to encompass the processes along with the technologies.

The main objective of thermal management is to ensure the temperature remains consistent for the functional and absolute maximum limits.

The temperature exceeding the limit may cause destruction physically or may lead to a system failure.
Therefore, metal core PCB is essential because efficient thermal management increases the feasibility, enhances durability, and reduces the failure rates.

It also enables the high circuit density design for the users.
Basically, thermal conductivity is a specific material from a property with the ability to conduct proper heat management as soon as it enters into the system.

The conventional PCBs share less thermal conductivity and also not capable enough to meet the increased demand for the thermal constraint required for high power dissipation PCB.

The best alternative to solve this problem is the Metal Core Printed Circuit Board.

2 Layers direct thermal path copper core pcb application

2 Layers direct thermal path copper core pcb are designed to dissipate heat generated by high-power LEDs,
which helps to increase the lifespan of the LED and improve its performance.
The aluminium base acts as a heat sink, which absorbs and dissipates the heat generated by the LED.

The 2 Layers direct thermal path copper core pcb is made by laminating a thin layer of copper onto an copper substrate.
The copper layer is then etched to create the circuit pattern.
2 Layers direct thermal path copper core pcb for LED lighting applications are available in various sizes and thicknesses, depending on the specific requirements of the application.
They are also available in single-sided, double-sided, and multi-layered configurations.
