Single band, high photoelectric conversion rate, uniform irradiation energy: the traditional exposure machine (mercury lamp) is a scattered light, which is composed of bubble shell, electrode and discharge gas. The emitted light source band is between 350-450nm, the spectrum is long, the utilization rate of ultraviolet light is low, and the energy uniformity is only 70-80%; UV LED exposure machine is parallel light source, emitting 365nm/395nm single band light source, without clutter energy consumption, and the energy uniformity can reach 95%, which is suitable for the use of precision circuit industry.
 
1. High efficiency and energy saving

Mercury lamp needs to be turned on in advance to preheat the equipment when in use, and it needs to be turned on all the time when working, which is very power consuming; UV LED uses ultraviolet diode chip to light up, which can be lit instantly. The output energy can be set by itself, which is very energy-saving and easy to operate.
 
2. No harmful substances discharged, safe and environmental friendly

The spectrum emitted by the traditional exposure machine (mercury lamp) has a wavelength below 200nm, which will change the oxygen O2 in the air and produce ozone O3 (there will be a little odor in the mercury lamp workshop), and the mercury lamp itself will also bring mercury pollution. At present, there is no effective method to deal with mercury pollution; The UV LED exposure machine has ultraviolet diode chip to emit light, which is the conversion of electric energy to light energy. There will be no pollution. It is a cleaner and environmental friendly curing method.
 
3. Long service life, no consumables

The service life of mercury lamp is 300-600h, and the bulb of mercury lamp needs to be replaced regularly; The use time of UV LED exposure lamp can reach more than 20000h. A UV LED curing light source can be used for several years, and the lighting effect will not be weakened.
