About the raw material chip characteristics and working principle of LED UV

th the development of UV curing technology, LED UV systems have gradually replaced traditional mercury UV systems due to their high efficiency, energy saving, and low temperature. LED UV chip as the core component, its performance directly affects the curing effect. Understanding the characteristics and working principles of LED UV chips and adopting reasonable control technology and power supply technology are crucial to ensuring stable operation of the system.

The spectral output of LED UV chips is the most significant difference from traditional mercury lamp UV systems. Mercury lamps produce a wider spectrum, covering UV-A, UV-B and UV-C bands, whereas LED UV chips usually focus on a narrower wavelength range, especially the 365nm and 385nm, 395nm . Those bands are the optimal reaction wavelengths for most UV curing inks and coatings, so the LED UV system can provide higher curing efficiency.

The light efficiency of an LED chip refers to how much ultraviolet light it can produce while consuming a certain amount of electricity. Compared with mercury lamps, LED UV systems are much more efficient.

LED chips generate a certain amount of heat when working, especially high-power LED chips. Excessive operating temperature will affect the stability and life of the chip. Therefore, good thermal management is the key to ensuring long-term stable operation of the LED UV system.

Thermal resistance design of the LED chip affects its heat dissipation ability. High-quality LED chips use efficient heat dissipation materials and structures to help conduct heat away effectively.

LED UV systems are usually equipped with specialized heat dissipation systems, such as water cooling systems, to ensure that the chip temperature is always within a safe range.

Through packaging and optical design, the chip effectively outputs the ultraviolet light generated and irradiates it onto the material to be cured.

LED chips are sensitive to current fluctuations. Unstable current will cause the LED chip to emit unstable light, or even damage the chip.

IUV’s unique technical solution uses a combination of constant voltage source and constant current source to ensure high-quality power supply, stabilize the power supply of the LED UV system and avoid voltage fluctuations.

LED UV systems require regular calibration to ensure that light intensity, wavelength and other parameters meet the requirements.

Use a photometer to check the light intensity regularly to ensure it meets design standards.

Use professional instruments to check whether the wavelength is stable to ensure that the system can continue to produce the required UV wavelength.

LED UV technology has become the mainstream of modern UV curing technology with its advantages of high light efficiency, low power consumption and long life.

Through effective thermal management, stable power supply, regular maintenance and protective measures, the long-term stable operation of the LED UV chip can be ensured and provide a good foundation for UV curing. Strong expert support for the application of UV curing technology.
