Many customers see “cold light source”, will think UVLED cold light source will not be like the traditional uv mercury lamp as heat, in fact, this is wrong, LED curing light source will still produce heat when used. In fact, what we call cold light source does not mean that when the light does not produce heat, but refers to the way the light is not converted from heat to light energy.
Currently widely used curing equipment – uvled curing machine can directly convert electrical energy into UV light (ultraviolet), is a typical cold light source. And thermal light source is converted from electrical energy to thermal energy, thermal energy is then converted to light energy. Strictly speaking, uvled curing light source light-emitting heat, due to UVLED curing lamp light radiation density is high, containing high energy, but also has a certain temperature, but the light-emitting temperature is not higher than the ambient temperature, so called “cold light source.
UVLED curing equipment often uses air-cooled and water-cooled two cooling methods. Fotanxi electronic technology research and development production of uvled curing light source, the use of unique heat dissipation technology, rapid heat discharge, improve the output irradiation stability and reduce wavelength drift.
UVLED curing light source no infrared emitted, no infrared heat radiation, the irradiated material surface temperature rise is small, while the traditional mercury lamp will make the irradiated material surface temperature rise 60-90 ℃, so that the positioning of the product displacement and thermal deformation, resulting in a series of problems such as a decline in yield. The use of led cold light source uv curing technology can be a good solution to the production of equipment heat, heat injury and other problems, to meet the plastic substrates, lens bonding and electronic products, optical fiber cable and other heat-sensitive, high-precision product bonding curing process requirements.
