Why is the UVLED curing machine a cold light source curing machine and also generates heat?Click [71] Publish Time:2022-05-11

When we introduce UVLED curing machine, we often say that it is a cold light source curing machine. But some customers will ask that the UVLED curing machine will have heat when in use. How can it be a cold light source? In fact, the so-called cold light source and hot light source of UVLED curing machine are not defined from the temperature, but from the perspective of electric energy conversion. A typical cold light source is a UVLED curing machine, which can directly convert electrical energy into UV light (ultraviolet light); and from electrical energy into heat energy, thermal energy into light energy, called thermal light source.

42923澳门金牛版-澳门彩1877com-u7cc金牛版-u7彩票u7cc-澳门彩1877ccWhat we call a cold light source is actually a luminous light source that has almost no infrared spectrum, unlike thermal light sources that contain an infrared spectrum. UVLED curing machine is a cold light source because the light it emits is almost all visible light.


So, why is the UVLED curing machine still hot? This is because the electric energy of the LED light source is only converted into about 30% of the light energy, and other energy is converted into heat energy, which must be transmitted by heat conduction. Therefore, the UVLED curing machine will also generate heat.

Therefore, the so-called cold light source of the UVLED curing machine is not cold, but it is more energy-efficient than the thermal light source because its electric energy is converted into light energy with relatively high efficiency.


In addition, since the UVLED curing machine generates heat, thermal design is also very important. If the heat cannot be released, it will affect the luminous efficiency of the chip. Therefore, Height-LED attaches great importance to the heat dissipation design of the UVLED curing machine. After scientific calculation of air-cooled water-cooled heat dissipation, improve the heat dissipation efficiency, ensure the long-term high-intensity use of the UVLED curing machine, protect the curing machine, prolong the service life, and slow down the decay speed of the UVLED curing machine.
