Application of thermal grease in heat treatment of LED lamp solid state light source

In order to achieve the purpose of daily lighting applications, it is usually necessary to increase the power of a single group of components to strengthen the output lumen of the unit. This results in the LED component producing higher temperatures during operation. If the heat is not dissipated in time, the LED junction temperature will rise rapidly, resulting in a series of problems, such as a decrease in luminous efficiency and an increase in the failure rate. Therefore, in the heat treatment of LED lamp solid state light source, the use of thermal grease for heat dissipation treatment is particularly important. In practical applications, the thermal conductivity and high temperature resistance of thermal conductive silicone grease need to be strictly tested. The heat transfer capacity of thermal grease can be evaluated by measuring the thermal conductivity of thermal grease by steady-state method or transient method. At the same time, the chemical composition of thermal grease is analyzed to ensure that its formula meets industry standards, which is also an important part of ensuring its quality.

In addition, in order to achieve better thermal conductivity, in the heat treatment of LED lamp solid-state light source, the following points need to be noted:

1. Ensure that the contact surface between the heat dissipation facility and the heating body is smooth and clean, so that the thermal grease can be evenly applied and form good thermal contact.

2, control the coating thickness of thermal grease, too thick may lead to increased thermal resistance, affecting the heat dissipation effect.

3. Select the appropriate thermal grease model and performance parameters to meet the heat dissipation requirements of specific application scenarios.

In summary, thermal grease plays an irreplaceable role in the heat treatment of LED lamp solid state light source. Through the rational use of thermal grease, the heat dissipation problem of LED lamp solid state light source can be effectively solved, and its service life and stability can be improved.
