Square LED Module Heat Sink

 

Square LED module heat sink is one of the LED module heat sinks type. There different shapes of LED module heat sinks.

 

There are several types of heat sinks used in LED modules, including passive and active heat sinks. Passive heat sinks are made of aluminum or copper and rely on natural convection to dissipate heat. Active heat sinks, on the other hand, use a fan or other cooling mechanism to enhance heat dissipation.

 

 

 

Our custom square heat sinks for LED modules provide optimized thermal management for COB, SMD, and mid-power arrays in space-constrained applications. Utilizing high-conductivity aluminum alloys (1050/6063), we engineer monolithic solutions with uniform thermal distribution across the entire mounting surface. Unlike circular designs, our precision square heatsinks for LED arrays eliminate corner hotspots while maximizing fin surface area within compact form factors – essential for modern LED panels, downlights, and horticultural lighting.

The size and shape of the heat sink depend on the specific LED module and application. Generally, larger heat sinks are more effective at dissipating heat, but they may not be practical for all applications due to space limitations.

 

 

 

 

Features of square led module heat sink:
1. Dimensions, flexible matching and strong versatility.
2. Matching the diversity of light sources, a wide range of applications.
3. Good heat dissipation performance and long service life.
4. The lens has ultra-high light transmittance, multiple angles are optional, and the light distribution is uniform.
5. Free serialization of full power to fully meet the needs of the program.
6. The protection grade is IP65, no need to apply glue for secondary waterproofing.
7. The surface treatment is anodized, corrosion-resistant and anti-rust.
 

 

 

LED modules can be used in various lighting fixtures such as street lights, tunnel lights, flood lights, garden lights, landscape lights, etc., and are especially suitable for the matching of traditional lamp renovation projects.
