mercury lamp will produce a lot of heat and infrared, will destroy the coating, so it needs to use a longer working distance, thereby reducing the use efficiency. Not only that, but also a lot of heat and infrared, high heat, cooling systems and air conditioning equipment, coupled with the huge size of equipment, energy consumption, short life, mercury, and ozone, these are the shortcomings of traditional UV curing mercury lamps.

But if we use UV LED as light source, we can get higher efficiency of UV range light. At the same time, the advantages of small volume and single wavelength make the UV light source can be very short from the coating, greatly improve the effective light source, and speed up the reaction time, so that the time is less than one millionth of a second (ms), no preheating, that is, on-demand, no need to use. Starting all day, greatly improving the effective use time.

Dr Chuong Anh Tran believes that there are not many manufacturers who want to do UV LEDs well, but there is a technical barrier. SemiLEDs are now firmly established in this field and will continue to provide better UV LED light sources to the market.
