The application of thermal conductive materials in mining LED bracket lights is mainly achieved through the following two ways:
Thermal conductive silicone grease filling
The fin type heat dissipation structure is filled with thermal conductive silicone grease, which evenly conducts the heat generated by the LED chip to the heat dissipation fins through the silicone grease. The thermal conductivity of this scheme can reach 3.0 W/mK, ensuring that the junction temperature of the LED is controlled below 65 ℃ and achieving a light attenuation of no more than 10% within a lifespan of 50000 hours.
Thermal conductive silicone sheet bonding
Some mining lighting fixtures use thermal conductive silicone sheets to bond components and heat sinks, with a thermal conductivity of 3.0 W/mK and a thickness of 0.5mm, achieving efficient thermal conductivity through bonding. This material can work stably in an environment of -50 ° C to 200 ° C, suitable for the heat dissipation needs of high-power LED chips.
Both solutions achieve efficient thermal conductivity through automated dispensing processes, with the former focusing on thermal conductivity efficiency and the latter on structural stability and maintenance convenience.
