Thermal Pad on LED Lights-Small Size, Great Effect!

时间： 2024-01-18 来源：Waermtimo News

技术问答

LED lights have many advantages such as energy saving, environmental protection, safety, long life, high brightness, easy maintenance, etc., not only general lighting but also used in various fields such as indication, display, decoration, backlight, etc. It’s called four generations of light sources.

How to make heat conduction more effective in LEDs (to effectively conduct heat generated during the conversion of electric energy into light energy) is a problem that the industry generally faces.

Fig.1

In the traditional heat dissipation method, the heat conductive material often used is thermal grease. Although the cost of the thermal grease is economical, it is inconvenient to operate ( the thermal grease cannot be evenly applied, and the heat conduction function cannot be well achieved, and cannot be widely promoted).

Fig.2

The appearance of the thermal silica pad is a good solution to this shortcoming. The thermal conductive silicone pad has ductility and can be laid over a large area between the heat-dissipating copper plate and the heat sink, the metal bracket, and the metal casing. Effectively solve the contact problem, so that transferring heat to the heat sink components to the greatest extent.

Fig.3

For example: Waermtimo's new TIM WT5912-H20 series of high-strength thermal pad, with high mechanical strength of thermal sheet, tensile rate >300%, with high toughness. It can effectively reduce vibration while conducting heat. It can be reworked many times and unbreakable, and it can tightly integrate irregular or complicated surfaces and has an excellent interface filling function.

In addition, the thermal pad has excellent thermal conductivity, insulation, flame resistance, cushioning, etc., and is suitable for use in LED lamps, displays, and other products. It improves production efficiency and the operation simple.

LED投影仪如何散热？

光学组件是LED投影仪中成像显示的核心部分，容易产生热并受热影响的主要部件是灯泡和液晶板及其附近光学器件。投影仪的投射成像技术要求光源输出度高，由于设备体积小巧、热量集中，投影仪多数的功率都耗散在一个很小的空间里。温度过高，会造成LED灯泡内壁的石英发生失透现象，产生白色斑点，引起局部区域温度异常升高，并进一步扩大，进而使亮度迅速衰减。
