Does UVLED equipment need to dissipate heat? What are its cooling methods? believe For everyone, UVLED is an emerging product, so the most impressive thing is the cold light source. However, such a "cold light source" itself also needs heat dissipation. Reasonable heat dissipation design will affect the entire set. UVLED curing equipment quality and service life.
I believe friends who have used laptops know that solid-state electronic devices dissipate heat, so for UVLED curing equipment The same is true. The heat dissipation and cooling of equipment is very important for UVLED chips. According to the current UVLED production process on the market, the photoelectric conversion efficiency of UVLED lamp beads needs to be improved. UVLED lamp beads can only convert 15-25% of electrical energy into light energy, and the other 75-85% of the electrical energy will be converted into heat. Therefore, UVLED curing equipment must be equipped with a cooling device to dissipate heat.
Due to the current limitations of semiconductor light-emitting diode chip technology, the UVLED photoelectric conversion rate needs to be improved, especially for high-power LED lamp beads. Due to their high power, more than 60% of the electrical energy will be converted into heat energy for release (with the development of semiconductor technology, the photoelectric conversion rate will gradually increase). This requires end customers to do a good job in heat dissipation when using high-power UVLED sources to cure products to ensure that high-power UVLED lamp beads can work normally.
Common cooling methods Currently, the cooling methods of UVLED curing equipment mainly include self-cooling, air cooling and water cooling.
It is worth noting that the higher the output energy of UVLED curing equipment, the more heat it generates. Therefore, while pursuing higher and higher radiant energy, it is also very important for UVLED curing equipment suppliers to control and eliminate system heat.
Natural cooling UVLED point light source, air-cooled UVLED surface light source , Water-cooled UVLED surface light sources With the improvement of UVLEDs and the increase in radiant energy, their requirements for system heat dissipation technology have also increased. For low-power, self-cooling or air-cooling is generally sufficient. If it is a high-power light source, water cooling must be used to lower the temperature.
