LED components and their drive electronics creat a lot of heat, and by dissipating the heat from the LED light source, the efficiency and life of the light source can be multiplied. Thermal management is the key factor of lumen output. For high lumen output applications. Although passive cooling heat sinks is sufficient for typical LED applications, passive cooling is not enough for high-brightness led lights and high power LED lights, so designers of LED lights should consider active cooling. In order to achieve the required lumen values with a small size factor, active cooling is the ideal solution for efficiently dispersing the heat generated by the LED components. Along with a heatsink, active cooling includes a subsystem, usually in the form of a fan, to force air over the heatsink, also known as forced air cooling.

In most cases, the designer can choose between passive or active cooling. Passive cooling uses natural air conduction and convection, also known as natural cooling, usually supplemented by heat sinks to accelerate both.The heat sink can solve the thermal management problem of low lumen LED light. However, a heat sink alone cannot cool 75 W or 100 W equivalent LED lights. Even if a heat sink had been designed for the application, the designer might have found it too large, expensive, and unwieldy.

Active cooling solution is an effective way to manage LED cooling. Dissipating heat directly from the core of the module reduces thermal resistance, making the entire led heat sink assembly more efficient. Especially for high brightness leds, active cooling technology provides better thermal performance than passive heat sink and improves performance, while greatly reducing the size of LED lighting fixtures, reducing total cost, increasing light output and extending LED life.
