Nano diamond thermal paste

Nowadays, with the maturity of chip technology, the input power of a single LED chip can be further increased to 5W or even higher, so it is becoming more and more important to prevent the heat accumulation of LEDs. If these heats are not effectively dissipated, the resulting thermal effects will become very noticeable, causing the junction temperature to rise, directly reducing the photons emitted by the chip and reducing the light extraction efficiency. The increase in temperature also causes the emission spectrum of the chip to red-shift, which causes the color temperature quality to decrease, especially for white LED devices that emit yellow phosphors based on blue LEDs. The conversion efficiency of phosphors also increases with temperature. High and low. At the same time, due to the repeated heating of the chip during the working process, the power module will continuously experience the thermal cycle load. Because the thermal expansion coefficient (CTE) of different materials does not match, the thermal stress of the layer will be generated, warping, cracking, and even generation. Failure and damage are also a major cause of the ultimate failure of the power module. Therefore, various thermal effects due to temperature increase will seriously affect the service life and reliability of LED devices.

The effect of heat on power LEDs is concentrated in chips of small size. The temperature of the chip rises, causing non-uniform distribution of thermal stress, chip luminous efficiency and phosphor lasing efficiency decreasing. The heat per unit volume is getting higher and higher. . The failure of the device is often closely related to its operating temperature. The operating efficiency of the device increases by 5-10 °C , and its failure rate is doubled.
When the temperature exceeds a certain value, the device failure rate increases exponentially. Statistics show that for every 2 °C rise in component temperature, reliability is reduced by 10%.
