Effortlessly Attach Your LED to a Heat Sink with 20mm-T-Tape-Star Pre-Cut Thermal Pads
Precise Fit for all Cutter 20mm Star Shaped MCPCB’s
|These pads are precision cut to fit the 20mm Star metal core PCB used for our assembled Cree XP, XML XR, and MCE LEDs. They make it easy to fasten the Star base directly to a heat sink without the need for screws or messy compounds and adhesives.|
High-Performance Design for Optimal Results
|Made from a high-performance, thermally conductive, pressure-sensitive acrylic adhesive tape, these pads electrically isolate the LED from the heat sink while providing an excellent dielectric barrier. With a thickness of 0.25mm and an operating temperature range of -30°C to +125°C, these pads are designed to provide optimal results in a variety of environments.|
Easy to Use with High Bond Strength
|These pads immediately bond to the target surface and their bond strength increases over time when repeatedly exposed to high continuous-use temperatures. They can be used instead of thermal epoxy, mechanical fasteners, or mounting clips, making them a convenient and versatile option for all your LED attachment needs.|
So if you’re looking for an easy, mess-free way to attach your LED to a heat sink, try these pre-cut thermal pads and experience the convenience and efficiency they provide!
Explanation of the TIM
Thermal interface material (TIM) is a crucial component in the assembly of LED lighting systems. LEDs generate heat as they convert electrical energy into light, and without effective thermal management, the excess heat can degrade the LED’s performance and shorten its lifespan. TIM is used to facilitate heat transfer from the LED to a heat sink, which helps dissipate the heat and keep the LED cool.
There are many types of TIM available for LED applications, including thermal pads, thermal pastes, and thermal tapes. Each type has its unique properties and advantages, but they all function to reduce the thermal resistance between the LED and the heat sink.
Thermal pads are pre-cut, electrically insulating pads that are often used in high-power LED applications. They are made of a soft, compliant material that conforms to the surface of the LED and the heat sink, creating a low thermal resistance pathway for heat transfer.
Thermal pastes are viscous materials that are applied between the LED and the heat sink. They typically contain a mixture of thermally conductive particles suspended in a silicone or grease-like base. When the paste is squeezed between the LED and the heat sink, it fills in any gaps and imperfections, creating a continuous thermal pathway.
Thermal tapes are double-sided adhesive tapes that have a thermally conductive layer between the two adhesive layers. They are easy to use and provide a strong, permanent bond between the LED and the heat sink while also facilitating heat transfer.
Choosing the right TIM for a specific LED application requires considering factors such as thermal conductivity, thermal impedance, operating temperature range, and application method. It’s important to use a TIM that can handle the heat generated by the LED and provide reliable long-term performance.
In conclusion, TIM is a critical component in the assembly of LED lighting systems. Using the appropriate TIM can significantly improve LED performance, increase lifespan, and reduce the risk of failure. With the wide range of TIM options available, it’s essential to consider the specific requirements of the LED application and choose a TIM that can provide effective thermal management.
