LED-UV Curing System Components

LED-UV Curing Systems consist of the following two components:
"LED Main Body Unit" and "Power Supply Unit".

The main function of the Power Supply Unit is to send LED On/Off signals to LED Main Body Unit.

In accordance with the signal sent from the Power Supply Unit, the LED Main Body Unit turns the LED On/Off.

Below is an example of use in a Printing Machine:
One LED-UV curing device is required for each ink color used in the printer, with one device installed between each of the ink colors. We can modify Curing Systems according to the area of irradiation or printer attachment adaptor.
Replacing ordinary UV lamps with LED-UV systems solves many problems.
We'd like to illustrate the benefits of "LED" below in terms of environmental friendliness and reduction of running cost as follows:
Environmentally friendly

Noritsu LED-UV usage results in absolutely no mercury disposal and no ozone emission, and it brings a vast reduction in CO₂ emission. Traditional UV lamps contain mercury, which is harmful to the environment, but Noritsu's UV LED do not contain any mercury, and therefore do not produce any mercury waste. Furthermore, the vast reduction in electricity consumption means that much less CO₂ is emitted when using LED.

Reduced running costs

Noritsu LED-UV curing systems take energy-efficiency to a whole new level. They only use one-tenth the amount of electricity that traditional UV lamps use. Furthermore, traditional UV lamps need to be left on all the time, but Noritsu LED-UV are only illuminated when needed, thus providing a high level of energy efficiency.

Low-temperature curing

The LED light source enables low-temperature UV curing. Traditional UV lamps release infrared rays and therefore emit an excessive amount of heat. Noritsu LED UV curing systems solve this problem because they use only ultraviolet light, not infrared.

Long life

Noritsu LED-UV curing systems have an amazing life of 15,000 hours or more. This means that when they are used for 4 hours a day they will last for over ten years, eliminating the need for replacement during this time. This results in a much lower running cost than traditional UV lamps.

Space-saving design

Noritsu's LED-UV curing devices take up a minimal amount of space because they have a compact structure with a small Power Supply Device and they do not require an exhaust duct. In contrast, traditional UV lamp Power Supply Devices are bulky and they require an exhaust duct, which means a much larger space is necessary. LED-UV is the ideal solution for those who want to save space.

Changing from traditional UV lamps to LED-UV systems brings a dramatic reduction in running costs due to the fact that, once installed, LED-UV does not need to be replaced for a very long time. So exactly how much can you save per year? Below is a simulation of when 4 LED-UV curing systems are installed in one printer. (One for each color used)

= 1,859kWH
Electricity charge: $0.15/kWH
$4,561.92 $278.85
Lamp Costs Cost of lamp: $700 / lamp
labor cost for replacement:
$10 / lamp
Lamp replacement:
1 time / year x 4 lamps		 Replacement of lamp:
0 time / year
$2,840.00 $0
Total $7,401.92 $278.85

In this simulation, power consumption is reduced by 28,554kWH and the electricity bill is reduced by $7,123.07 for one year. And with LED-UV, you do not have to install exhaust ducts, and the overall room temperature is cooler because LED does not produce excessive heat like traditional UV lamps, further enabling savings in installation expenses and air conditioning.

Note: Electricity rates and other costs vary from region to region. The actual amount you pay for electricity, UV lamps and labor may be different.
We work side-by-side with the customers to meet their individual needs.
We evaluate the results of demo product tests to help us meet the exact needs of the individual customers.
Noritsu has made demo products available to match against the required specifications of our customers. When necessary, we customize to make a product that fits the customer's exact needs in terms irradiation width, wavelength, number of lines, etc.
Air-cooled 1-line type　
Irradiation width : 200mm / 250mm
Wavelength : 365nm / 385nm
Air-cooled 2-lane type
Irradiation width　 : 200mm/300mm
Wavelength : 365nm/385nm
Water-cooled 4-line type
Irradiation width　 : 450mm/700mm
Wavelength : 365nm/385nm
In the case that there is no demo product that meets the customer's required specifications, we will analyze the possibility of making a custom product. In that case we will perform an optical simulation and make the custom model based on the results of the simulation. The following are actual examples of simulations we have performed for area irradiation models to meet the needs of customers with specific demands.
LEDs are "Light Emitting Diodes"
LED chips are made from n-type diodes and p-type diodes, and they release light when these two types of diodes are joined together and a voltage is applied. p-type diodes have many electron holes and n-type diodes have many electrons. Joining these two diodes (PN junction) and applying voltage causes the electrons and electron holes in the LED chip to move, resulting in an electric current.
Electrons and electron holes come together and recoupling occurs. The energy it has is converted into a smaller amount of energy, and the extra energy that occurs is released in the form of light.

The color of the light that the LED emits depends on the type of the diode material that makes up the chip. It was 35 years after the development of red LED in 1962 that ultraviolet LED was developed.

UV curing resign is generally composed of monomers, oligomers, initiators, and other additives. When ultraviolet light is projected onto the UV curing resign, a photopolymerization reaction occurs and hardens or "cures" the monomers, oligomers and polymers as a result. This technology is used in the printing segment and many other segments including coating, electronic part assembly, and adhesive-related applications.

Noritsu's curing devices have been well received in the market, achieving a high level of customer satisfaction.

Q.
What is the wavelength of the ultraviolet light emitted from Noritsu LED-UV units?
A.
Currently our equipment produces UV wavelengths of 365nm or 385nm. We are always developing new products and we can also customize products in our current line to meet specific needs, so please contact us and see what we can do for you, even if you have needs for a UV wavelength other than the ones listed above.
Q.
What is the life of Noritsu LED-UV products?
A.
Our products are designed to last 15,000 hours or more. LED units gradually begin growing dimmer when they are used extensively. We define the product life as the period it illuminates at 100% to 70% brightness as compared to the initial intensity when it began to be used. So in other words, when the light intensity falls below 70%, we deem the life of the product to be over, in which case we can replace the LED PCB.
Q.
Do I need to install any ancillary equipment?
A.
No.　Noritsu products produce no ozone and very little heat. Therefore, there is no need for ducts or blow fans, etc.
Q.
What kind of maintenance is required?
A.
Cleaning the protective glass and the intake filter on the curing device so as to keep them free of dust, smudges etc.
Q.
What would happen if the product were to break?
A.
We have a send-back program just in case something goes wrong. To minimize downtime we provide a substitute product right away for you to use until the original has been repaired.
Q.
What kind of customization do you do?
A.
We make custom products to meet specific needs in irradiation width, adapters, LED specifications, etc.
