2. Performance comparison of LEDUV and traditional mercury lamps
| LEDUV | Mercury Lamp Mercury (Hg) Iron (Fe) or Gallium (Ga): | |
| Light source characteristics | Instant on and on, electronic control, low temperature | Long startup time, need to warm up, standby, high temperature |
| Energy consumption | Energy saving, single wavelength, high luminous efficiency, UV-LED can directly convert electrical energy into UV light, and emits single-band ultraviolet light, 365nm-405nm these bands . Due to both lighting and lighting, the actual energy consumption is 5-10KW | Traditional UV mercury lamps only account for a part of the ultraviolet spectrum, which is really effective for curing. At the same time, the photoelectric conversion efficiency is low, and the energy consumption is large 17KW |
| Environmental, production impact | Environmental protection, does not generate infrared rays and ozone, can maintain a good working environment, and is safer and more environmentally friendly than traditional mercury lamps. | Traditional mercury lamps generate ozone, infrared rays, and emit a lot of heat, which can easily damage heat-sensitive substrates. |
| life structure | Long service life, simple structure and low maintenance cost The service life of UV-LED lamps can reach more than 150 million hours, which is more than 15 times that of traditional mercury lamps, and the light decay is very slow, and the service life is not affected by the number of switches. There are also no accessories such as lamp shades, so almost no maintenance is required, reducing maintenance costs | The mechanical structure of traditional mercury lamps is complex, and the shutter mechanism, reflector, and lamp need to be replaced regularly |
| Radiation area | Any size can be customized, LEDUV lamp beads can distribute power and wavelength as needed | Fixed size, immutable radiation area, easy to damage printing machinery |
| printability | At this stage, more than 95% of ordinary UV ink can be dried, and the drying effect of white ink is better than that of traditional UV lamps. The drying effect of ordinary UV varnish cannot meet the requirements and needs to be combined with mercury lamps | Traditional UV is more mature to adapt to existing UV printing materials |
3. Energy-saving analysis of LEDUV transformation project examples:
JY04# offset printing machine UV lamp energy-saving renovation project---power consumption measurement report
Project: Transformation of traditional UV lamps in color group of offset printing machines into LED UV lamps
| UV Lamp Configuration | Active power | reactive power | 1 hour power consumption (kWh) | Remark |
| Traditional transformer + UV mercury lamp | 21.96 | 29.75 | 21.96 +30 (reactive power) | Measured during normal operation of a single lamp |
| Electronic transformer + UV mercury lamp | 21.40 | 3.68 | 21.40 | |
| LED UV light | 9.70 | 0.00 | 9.70 |
According to the measured data (the data in the above table is obtained by actual measurement), the report is as follows:
1. The power consumption of electronic transformers and traditional transformers is not much different (active power), and the reactive power is quite different.
2. LED UV lamp, compared with the measured data, the energy saving is obvious, and the energy saving is more than 60%.
| UV Lamp Configuration | Roller surface temperature of long-order production machines | Downtime during production | Impact on products and machines | Safety | energy saving |
| Traditional transformer + UV mercury lamp | 85～90℃ | Keep 50% power on |
