Thermal grease is used in the manufacturing process of LED lamps. As a heat dissipation material, why is thermal grease used in LED lamps? This question bothers many people. In fact, LED lamps cover a wide range, not only the common LED advertising lamps, but also LED power supplies, LED street lamps, LED water drop viewing lamps, LED point light sources, LED indoor downlights, LED floodlights, etc. The following will introduce to you why thermal grease is needed in these fields.
What are the characteristics of LED thermal grease?
1. The main characteristics of LED thermal grease are good thermal conductivity and electrical insulation performance. It is low volatile during use. The volatile silicone oil will not pollute the LED components and will not affect the light emission. It can still maintain good heat dissipation performance after years of use, ensuring that the LED will work for more than 10 hours without heat dissipation problems and will not burn the lamp beads.
2. Secondly, LED thermal grease also has the properties of weather aging resistance, water resistance and ozone resistance. It has stable performance during use, will not corrode materials such as copper, steel, and aluminum, and extend the service life of LED and safety in use.
3. Led thermal grease is a non-toxic and odorless paste. This paste will not affect the operator's body, solidify, or dry up during use. In particular, it has good temperature resistance, will not flow or separate oil at high temperatures, but it is necessary to understand the temperature resistance index before construction, and it cannot be used in areas that exceed the temperature resistance index.
Is it necessary to use Led thermal grease?
According to the current electrical safety performance requirements and insulation and heat dissipation indicators, LED thermal grease must be used, and products with good quality and good reputation must be used, such as TENSAN, which focuses on the research of thermal grease and provides customized thermal grease application solutions. LED lamps that do not use LED thermal grease are prone to various safety hazards during use. For the safety of users, such products cannot be subject to safety monitoring and cannot be introduced into the market through formal channels.
Led thermal grease is used in the same way as ordinary thermal grease. It can only be applied in the middle of the heating element and the heat dissipation facility. Whether it is coating or potting, the construction thickness needs to be mastered so that good heat dissipation performance can be demonstrated.
