UV LED light sources

Why will UVLED lamps replace high-pressure mercury lamps? The advantage of UVLED lamps and high-pressure mercury lamps is that there is 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 optical fiber cables.
Environmentally friendly and pollution-free 
The traditional mercury lamp curing machine uses a mercury lamp to emit light. There is mercury in the bulb, which makes the waste disposal and transportation very troublesome, and improper handling can cause serious environmental pollution. 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. UV intergrator is used to test the uv energy and uv irradiation intensity of the curing light sources.
Super illuminance
High-power LED chips 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, which makes the UV adhesive cure faster and shorten Production time has greatly improved 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 always remains at the maximum. Because of its super concentrated illuminance, compared with mercury lamps, UV LED shortens the irradiation time of the operation and improves the production efficiency.
