UV Curing lamp, literally, UV It refers to the abbreviation of ultraviolet in English. Combined with the curing lamp, it is a lamp that converts ultraviolet radiation to solidify the coating from liquid to solid through ultraviolet rays. It is generally used in printing plate making, flexible packaging color printing, furniture industry, wooden floor decoration materials, printed iron cans, shoemaking industry, semiconductor and printed circuit board ink drying, etc.
Why are traditional mercury curing lamps used? UVLED What about curing lamp replacement?
1.Luminous efficiency, band and energy consumption
The electrical conversion efficiency of mercury curing lamps is relatively low, and the emission spectrum is very broad. Only a part of the ultraviolet spectrum that has the real curing effect accounts for a large energy loss. and UVLED can directly convert electrical energy into UV Light, and it emits single-band ultraviolet light. The light energy is highly concentrated in the designated ultraviolet light band. The most widely used in the market is 365nm、385nm、395nm、405nm Wait for a few bands.
2.Infrared and ozone
Mercury curing lamps produce infrared rays and a large amount of heat energy, which can easily cause damage to heat-sensitive substrates. They also produce ozone during use. Excessive ozone concentration can cause allergies to the oral, nasal, and eye mucous membranes, and is harmful to the human body if inhaled. UVLED The curing lamp uses a cold light source, which will not cause damage to heat-sensitive substrates, and uses ultraviolet light with a longer wavelength, which does not produce ozone during the curing process, making it relatively safer and more environmentally friendly.
3.preheat
Mercury lamps need to be preheated in advance, and cannot be switched on and off frequently in order to maintain lamp life and working efficiency. UVLED The curing lamp can be turned on and off instantly, the output energy can also be set according to the actual situation, and can be controlled electronically using a program.
4.Service life and cost
UVLED Wait until the service life is1Ten thousand-5More than 10,000 hours, which is the limit of traditional mercury lamps10More than times, and the light decays very slowly, and the service life is not affected by the number of switches. Maintenance LED The lamp does not use mercury and has no lampshade or other accessories, so it requires basically no maintenance.
5.Flexible use
LED Curing lamps can customize the effective irradiation area according to needs. The size of the light source equipment is relatively small and it can adapt to more environments than mercury lamps.
Why are mercury curing lamps replaced by UVLED curing lamps? After many comparisons, traditional mercury lamps are inferior to UVLDE lamps in terms of luminous efficiency, wavelength band, energy consumption, environmental protection, service life, cost and flexible use, so mercury lamps will gradually be replaced by UVLED lamps.
