Why will UVLED lamps replace high-pressure mercury lamps? What are the advantages of UVLED lamps compared to high-pressure mercury lamps?
No heat radiation
High-power LEDs do not emit infrared light. The surface temperature of the irradiated product rises below 5 degrees Celsius, and the traditional mercury lamp method of ultraviolet curing machine generally raises the surface of the irradiated product by 60 to 90 degrees Celsius, which causes the positioning of the product to shift, resulting in product failure. The UV-LED curing method is suitable for thermally sensitive and high-precision bonding process requirements such as plastic substrates, lens bonding, electronic products, and fiber optic cables.
Environmental protection and pollution-free
The traditional mercury lamp curing machine uses a mercury lamp to emit light. There is mercury in the bulb, which makes waste disposal and transportation very troublesome, and improper handling can cause serious pollution to the environment. The LED curing machine uses semiconductors to emit light, and there is no environmental pollution. Therefore, the use of LED curing machine is more environmentally friendly.
Super illuminance
The high-power LED chip and special optical design achieve high-precision and high-intensity irradiation of ultraviolet light; currently, the maximum output of ultraviolet light reaches 200,000 mW/m2. Using the latest optical technology and manufacturing process, it has achieved a higher intensity output and uniformity that is more optimized than the traditional mercury lamp irradiation method, which is almost twice the luminosity of the traditional mercury lamp method, so that the UV adhesive is cured faster and shortened The production time greatly improves the production efficiency. When the traditional mercury lamp type point light source curing machine increases the irradiation channel, the increase of the channel will cause the output energy of a single irradiation channel to decrease. With LED-type irradiation, each irradiation head emits light independently, and the irradiation energy is not affected by the increase in the channel, and is always kept at the maximum value. Because of its super concentrated illuminance, compared with mercury lamps, UV LED shortens the irradiation time of the operation and improves the production efficiency.

Low energy consumption
The effective luminous efficiency of the UV LED method is more than ten times higher than that of the mercury lamp method. At the same time, no matter whether the mercury lamp is irradiated effectively or not, the mercury lamp needs to be continuously lit, and the electricity is always in a state of consumption. The UV LED method consumes power only during irradiation, and almost zero power consumption during standby. A simple calculation can be made. The energy saved by each point light source curing machine: 270 (watts) * eight (hours) * three hundred and sixty-five (days) = 800 (kwh)
It can be seen that each unit can save 1,000 yuan per year with only electricity consumption. Not only that, by saving electricity, each car can indirectly reduce carbon dioxide emissions by 1.4 tons per year, which is equivalent to the annual displacement of a car.
Simple installation and space saving
The volume of the LED curing machine is only one-fifth the size of the traditional curing machine, which makes the installation of the equipment easier and reduces the occupation area of the production site. High reliability design. From circuit design, optical design, system optimization to component selection, implement ST -LED's consistent high-reliability design concept ensures the stability, reliability and curing consistency of the equipment.
In summary, UVLED light source has significant advantages that are incomparable with high-pressure mercury lamps, and it is the preferred curing light source for industrial light curing applications at present and now.
