Application of thermally conductive adhesive in LED lighting fixtures


LED lighting, known as the fourth generation lighting technology, is constantly recognized and favored by the market because of its many advantages. Various companies are also continuing to deepen their technical research and development on LED lighting fixtures. However, the heat dissipation problem of LED lighting fixtures restricts its performance. One of the key factors.

Thermal adhesive is an adhesive with good thermal conductivity, usually composed of organic compounds and thermally conductive particles. It mainly fills gaps to transfer heat and completes heat transfer between heating parts and heat dissipation parts. Its main features are good thermal conductivity, good insulation properties, strong adhesion and long service life. In the manufacturing of LED lighting fixtures, thermally conductive adhesive is widely used in the bonding of thermally conductive materials such as radiators, heat sinks and heat sinks to improve the heat dissipation effect and stability of LED lighting fixtures.

Thermal conductive glue selection

Choosing a suitable thermally conductive adhesive is the key to ensuring good heat dissipation of LED lamps. When selecting a thermally conductive adhesive, you need to pay attention to the following aspects:

1. Thermal conductivity of thermally conductive adhesive: The thermal conductivity of thermally conductive adhesive directly determines its thermal conductivity. Generally, the higher the thermal conductivity, the better the thermal conductivity.

2. Temperature resistance of thermally conductive adhesive: When LED lamps are used, the chip will continue to generate heat, and thermally conductive adhesive needs to be able to operate in high-temperature environments without failing.

3. Operating performance of thermally conductive adhesive: The operating performance of thermally conductive adhesive is also a factor that needs to be considered when selecting, such as gel time, viscosity, hardness, etc.

Application of thermal conductive adhesive

The coating of thermally conductive adhesive can form a uniform thermally conductive layer between the LED chip and the thermally conductive material, tightly fixing the LED chip and the heat sink together to achieve the dual effects of heat conduction and heat dissipation. At the same time, thermally conductive adhesive can also optimize the design of LED lamps, reduce the size of LED lamps, improve the heat dissipation efficiency of the lamps, and enhance the reliability and stability of the lamps.


When using thermally conductive glue, you also need to pay attention to the following points:

1. Remove dust, oil and other impurities on the surface of the adherend to ensure that the thermal conductive adhesive can be evenly coated on the surface of the thermal conductive material.

2. Apply the appropriate amount of thermal conductive glue as required according to the characteristics of the thermal conductive glue to avoid applying the thermal conductive glue too thick or too thin, which will affect the heat dissipation performance of the LED lamp.

3. Select appropriate thermal paste application tools and techniques to ensure uniform coating and good pressure balance.
