Peak Irradiance & Energy Density There are two key parameters of an LED lamp that should be understood for the purposes of optimizing cure and establishing a process window. Identifying this process window will result in the most durable and desirable finish, as well as acceptable adhesion and surface cure: peak irradiance and energy density. Peak irradiance, also called intensity, is the radiant power arriving at a surface per-unit area. With UV curing, the surface is the cure surface of the substrate or part, and a square centimeter is the unit area. Irradiance is expressed in units of watts or milliwatts per square centimeter (W/cm² or mW/cm²). Peak irradiance is instrumental in penetration and aiding surface cure. Peak irradiance is affected by the output of the engineered light source, the use of reflectors or optics to concentrate or contain the rays in a tighter surface impact area, and the distance of the source from the cure surface. The irradiance for UV LEDs at the cure surface decreases quickly as the distance between the source and the cure surface increases. Energy density, also called dose or radiant energy density, is the energy arriving at a surface per-unit-area during a defined period of time (dwell or exposure). A square centimeter is again the unit area and radiant energy density is expressed in units of joules or millijoules per square centimeter (J/cm² or mJ/cm² ). Energy density is the integral of irradiance over time. A sufficient amount of energy density is necessary for full cure.

When uv cure lamps are properly used and maintained, they provide consistent, reliable and accurate results for the adhesives, coatings and inks they cure. uv cure lamp But like any light source, UV lamps don’t last indefinitely – they have a defined operational lifespan and, over time, their performance degrades to the point where they can no longer deliver effective curing. Fortunately, understanding the factors that contribute to UV lamp degradation and recognizing the signs of decline can help you avoid unexpected downtime and maintain efficiency throughout your production process. Medium pressure mercury-vapor bulbs are the industry standard for many curing applications, delivering high spectral output with major wavelength peaks in the UV region of the electromagnetic spectrum, from 250 nm to 400 nm.uv cure lamp By varying the composition of a bulb’s mixture with noble gases and metal halides, different absorption profiles can be achieved to match specific product formulations. A common misunderstanding is that the UV intensity of nail polish curing lamps can be determined solely by their wattage.uv cure lamp While a higher wattage bulb is generally considered more powerful, the irradiance window is not necessarily proportional to this value and can be misleading for consumers.  

How to Use a UV LED Curing Lamp With a Water Cooling System The UV LED curing lamp is the most versatile, high-performing and energy-efficient light source available today.water cooling uv led curing lamp It can be used for many types of printing, coating and bonding applications. However, it is important to understand a few key details about the light before deciding if it is appropriate for a specific application. The key benefits of UV LED technology include instantaneous turn-on/turn-off, fast and uniform drying/curing, low heat emission, and a small form factor, making it ideal for integration into machinery with limited space.water cooling uv led curing lamp It can also be significantly more energy efficient than traditional arc-based UV sources, and it has the potential to reduce energy costs by 65% or more over a lifetime of 20,000 operating hours. Early UV LED systems were not powerful enough to cure at conventional sheetfed and web offset print speeds, but technological advances have made it possible to deliver sufficient peak irradiance and energy density for most commercial printing applications — including digital inkjet, spot cure, and screen.water cooling uv led curing lamp In addition, new LED lamp designs and application-specific formulations make UV LED curing systems applicable for a much wider range of printing processes than previously possible. To achieve proper, consistent UV curing of the substrate, it is necessary to control a few variables, such as power density, irradiance, and energy. The amount of energy needed to cure a substrate depends on the wavelength (nm), irradiance, and power density of the UV source, as well as the type of coating being applied to the substrate. These factors can be impacted by temperature, humidity, and other environmental factors. A water cooling system is essential for UV LED curing systems that require high intensity, as it has a higher thermal conductivity and specific heat capacity than air. It can dissipate heat more effectively, helping to maintain consistent UV curing performance and extending the life of the LEDs. It is also critical to properly monitor the cooling system, as it can help identify potential problems before they cause unexpected downtime and loss of productivity. To maintain the highest level of performance and efficiency, a water-cooled UV curing system requires a chiller that continuously circulates 6 liters of cool water through the LED module. This helps prevent the buildup of condensation on the lamp surface, which can degrade the LED chip and impact the intensity of the UV output. The cool water also helps to prevent dust or debris from entering the LED module and potentially contaminating the product. Water-cooled UV systems typically have a more compact and less expensive form factor than air-cooled systems, and they can run quieter, without the need for fans that create noise and may blow dust or debris onto the product. Regardless of which type of cooling is chosen, it is important to follow the manufacturer’s recommended guidelines and specifications for each UV LED curing system. This will ensure that the system is properly matched to a specific application and will continue to perform consistently for years to come. Tags: support custom | uv led fatory
