What UV LED Linear Light Source is

UV LED Linear Light source has High power irradiation area, saving, environmental protection, fast drying.

1.Different solvents, the light-curing ink dilution monomer is involved in the chemical reaction, its molecular weight is large, so the ability to reduce viscosity is limited. And ordinary ink solvents do not participate in the reaction of 100 percent volatilization, but can greatly reduce the ink viscosity.
2.The influence of pigment. The pigment of UV LED ordinary ink hardly affects the drying speed. Ink of different colors is composed of different pigments, the same substrate and the same auxiliary agent. But UV LED light curing ink situation is different, because different colors are on different wavelengths of light selective absorption and conditional reflex, so different color printing ink curing speed.
3.All visible light is fully reflected and requires high energy. Black absorbs all of the light in the theory, but to the light shade effect, because of pigment particle hinders ink curing deep, UV LED also needs higher energy, that is why the curing speed lower.

4.UV LED cold light source and ink are closely related. Whatever UV LED exposure area, light intensity and son on have a great relationship with ink. Long service life, LED life is up to 20,000 hours, reduce the cost of consumables.
5.Security monitoring camera UV glue adhesive small parts, UV LED label printing surface light source, according to practical application of customers, customized UV LED surface light oven.
6.UV LED Oven is a cold light source, no thermal radiation, the temperature of irradiated products is almost constant.

The Application of UV LED Area Light Source Glue Curing Lamp in Ink Glue Industry

UV LED has another advantages, that is, it has widely adaptation. It is suitable for all kinds of materials, such as UV LED curing glue. The performance of UV glue adaptive wide edge is suitable not only for automatic production line, but also for semi-automatic line. In general, as long as the current production line with UV curing equipment and the corresponding assembly tools to modify a little, to ensure that the ultraviolet light can illuminate the adhesive surface, adaptability is reflected in the materials properties of UV glue is very wide, such as from the A3 D69 hardness.

Compared with other alternative technologies, UV LED has obvious environmental benefits. Compared with fluorescent lamps, the energy consumption of UV light-emitting diodes is reduced by 70%. In addition, ultraviolet ray passes ROHS authentication, do not contain the harmful substance mercury that CCFL technology common. UV LED is smaller and more durable than CCFL. Because UV LED has anti-vibration and anti-impact performance, the loss is small, so the garbage and cost are reduced.

Curing process is a solvent-free process, without volatile organic compounds, can reduce environmental pollution. The requirements of the current environment is very high. The printing industry is an important source of environmental pollution, which uses the ink and other materials have a certain degree of volatility, causing environmental pollution. UV curing technology can overcome this shortcoming and reduce the use of solvent for printing. UV LED curing technology is a low temperature curing technology, which can meet some printing requirements and reduce the waste of printing resources and the printing cost.

The traditional UV curing system uses ultraviolet mercury lamp to irradiate. Generally, the use of UV lamp in daily life needs to replace the bulb after using 1000~3000 hours. But UV LED light curing system life is up to 30000~40000 hours, which do not need to replace the lamp. UV LED cold light source mode only can be lit when ultraviolet light is needed. According to DUIY = 1/5 (preparation time = 5 exposure time = 1), LED life is 30-40 times longer than mercury lamp mode. Greatly improve the efficiency, but also very energy efficient, and the traditional UV mercury lamp curing systems need a slow start (not the moment of light), open and close the light bulb life, and must always lit up, causing unnecessary waste of energy.

The Principle of UV LED Ink Drying

The polarizing polymerization of fry vegetable oil as connection material in air was carried out, changing the molecular morphology of vegetable oil. Therefore, UV ink is fixed on the substrate surface and dry. Ink drying uses oxidation polymerization to change oil form a low molecular weight liquid into a reticular solid. Reticular macromolecular solid is a process called ink drying. Similar to UV curing effect, ink after drying, surface gloss high, ink film solid, scratch resistance.

The principle of UV ink UV light curing : UV ink is cured by ultraviolet radiation. UV ink curing needs to add a small amount of photo-initiator. Polymerization takes place under the combined action of photo-initiator and ultraviolet ray, that changing the molicular shape of the ink curing. This reaction can be done in seconds or less.

Intermittent rotary machine with UV LED curing light source

Wireless Operation System UV Energy Meter

Introduction
The EIT Instrument Markets MicroCure ® is a radiometer that addresses UV measurement and process control in areas where radiometer placement is difficult. The MicroCure ® combines its compact size and adaptability to address a variety of demanding physical and thermal environments. These attributes make it possible to obtain measurements in curing applications that were previously inaccessible to radiometers.
The MicroCure ® radiometer is a microprocessor-based, calibrated, electro- optic instrument that measures and accumulates total UV energy and UV irradiance applied to its measurement surface. The DataReader reads and displays the data collected by the MicroCure ® radiometer.

Establishing a Cure or Process Window
A cure or process window is a set of parameters that defines equipment settings and run conditions to ensure proper curing. A cure window gives the user assistance in troubleshooting deficiencies in a UV process. Ideally, tests are run for every combination of coating and substrate so that a history can be obtained. This history helps establish baseline parameters for various chemical and material combinations and provides important information for process control. The operator can compare a current measurement to the cure window and adjust the process to get the desired curing results.
The process value is often defined as total energy or total energy produced by a system. It is the mathematical integration of lamp intensity over time. The MicroCure ® derives this value by measuring instantaneous lamp irradiance during the run and then summing them together. The process value must be maintained to get complete UV curing every time.

Handling and Safety Precautions
Due to the radiometer's data transfer, case configuration, and the applications for which it was designed, the following precautions should be observed to ensure the radiometer's performance.
• Avoid conductive materials, including process chemicals, process vapors, and anti-static mists when handling the MicroCure ® . These materials may cause the unit to short, reset and lose stored data.
• Handling the MicroCure ® with gloves reduces the chances of a short occurring.
• Do not let the MicroCure ® radiometers travel through print stations, die cutters, pinch rollers or other processes which may damage both the radiometers and your equipment.
• Do not short the two case sides of a MicroCure ® together. Doing so will reset the unit and any stored data will be lost.
• Do not allow MicroCure ® radiometers to touch each other. Data loss or corruption may occur.
• Do not mark or label the MicroCure ® radiometer case.

Operation
1. Insert the MicroCure ® into the slot in the upper left side of the DataReader.
2. Press the RESET button to move the unit from standby/sleep mode to turn the unit on to active data collection mode. The DataReader will briefly display the software version (Px.xx), "rxx" where "xx" is the number of unit resets, then "0.00" to indicate that the unit is ready to take a reading.
3. Remove the MicroCure ® from the DataReader and place it in the UV process with the optics aperture towards the UV source.
NOTE: The MicroCure ® must be exposed to UV energy within four minutes after being reset. Otherwise, the MicroCure ® it will go back into standby/sleep mode. The DataReader automatically shuts down after thirty seconds of inactivity.
4. Remove the MicroCure ® from the UV environment and place it back into the slot in the DataReader.
5. Press the SELECT button. The DataReader will display the total UV energy in Joules per square centimeter (J/cm²) or the irradiance in Watts per square centimeter (W/cm²). Press and hold the SELECT button to toggle between total energy and irradiance.
6. Press the RESET button when the reading is displayed to clear the current reading and to set the MicroCure ® for its next reading.

Error Messages
The DataReader displays error messages if there is a problem with it or the MicroCure ® .
If "---" is displayed, communication between the MicroCure ® and the DataReader has failed. Re-insert the MicroCure ® into the DataReader and retry.
If "LO BATT" is displayed, the MicroCure ® 's battery is low. If this occurs within a 200-reading/ 1-year period from date of purchase, the unit or battery may be defective. The battery in the MicroCure ® is not user replaceable, contact EIT Instrument Markets for assistance. When the DataReader's battery is low, it will scroll "LO" ten times and then shut down. The battery in the DataReader is user replaceable. Refer to the Maintenance section of this manual for replacement instructions.
If the DataReader displays a numeric error code, contact EIT Instrument Markets for assistance.

High Speed Application
The MicroCure ® 's sample rate of 2048 samples per second produces accurate readings at high system speeds. Since total energy readings are directly proportional to exposure time, a reading for a high-speed system can be derived from a reading taken at a lower speed. For example, if the system speed is 600 feet per minute (fpm), jog the system down to 60fpm and take an energy reading. This reading represents the UV total energy of the system at 1/10 th the speed. To translate this to 600fpm, simply divide the energy reading by 10.
NOTE: Irradiance readings with the MicroCure ® should be consistent and are not dependent on speed. The MicroCure ® should register similar irradiance readings when consistent data collection techniques are .
The irradiance values displayed by the MicroCure ® are instantaneous peak irradiance values versus average or RMS irradiance values. The irradiance values are similar to the irradiance values collected with EIT instruments used in the “Smooth Off” (instantaneous peak) mode versus “Smooth On” (average peak) mode.

Maintenance
MicroCure® Radiometer Clean the MicroCure ® Radiometer's aperture with a cotton swab and isopropyl alcohol. Use isopropyl alcohol and a soft cloth to clean the case of the MicroCure ® .
Do not open the radiometer's case. There are no user-serviceable parts inside the unit.
The MicroCure ® radiometer is given a one-time calibration before it is shipped from EIT Instrument Markets. It is specified to take 200 readings or last for approximately one year. Once the unit meets one of these conditions, it must be replaced.
The MicroCure ® Unit contains a battery. Any expired MicroCure ®  units may be returned to EIT for proper disposal of the battery.
