company news about Low power consumption, high output: Handheld UV curing lamps lead UV paint coating into the "low power consumption" era

In modern industrial manufacturing and high-end repair fields, UV (ultraviolet) curing paints have become the "darling" of surface coating due to their high hardness, scratch resistance, and environmental friendliness (low VOC emissions). However, traditional mercury lamp curing equipment is often accompanied by high energy consumption, slow preheating, and enormous heat dissipation pressure.

With the rapid advancement of semiconductor technology, handheld UV LED curing lamps are breaking this deadlock with astonishing speed. They not only make application more flexible but, with their "low power consumption and high output" characteristics, are sparking a green revolution in coating efficiency.

In the past, even small-area paint repairs or touch-ups on irregularly shaped parts often required the use of large tunnel curing ovens or high-powered fixed mercury lamps. This "using a cannon to kill a mosquito" approach not only resulted in serious energy waste, but also caused deformation of heat-sensitive substrates such as films and plastics due to the high heat output.

The advent of handheld UV curing lamps has enabled a shift from "global heating" to "precise localized application." Their core advantages lie in: Immediate use and zero standby power consumption: Unlike mercury lamps that require 5-10 minutes of preheating, LED handheld lamps achieve microsecond-level switching, consuming power only when irradiating the paint surface. Extremely high photoelectric conversion efficiency: The electro-optical conversion efficiency of UV-LEDs is far higher than of traditional light sources, meaning that while outputting the same curing energy (joules/cm²), its power consumption is only 10%-20% of that of traditional equipment.

The curing quality of UV paint is highly dependent on the angle and distance of light irradiation. Fixed production lines are often powerless for grooves, corners, or surfaces of extra-large equipment. Handheld UV curing lamps, with their lightweight design, allow operators to guide the beam of light at close range, covering every inch of the paint surface, much like "graffiti." This near-field curing method greatly improves the utilization rate of light energy—because light intensity follows the inverse square law, halving the distance means doubling the energy density. This "near-field reinforcement" strategy is the underlying technological logic for achieving "low power consumption and high output."

The "low power consumption" not only saves electricity but also provides ultimate protection for process quality. Due to reduced infrared heat radiation, the surface temperature rise of the substrate during the curing process with the handheld UV lamp is extremely low, a phenomenon known in the industry as "cold curing."

This is crucial for UV paint coating:

• Prevention of sagging and wrinkling: Precise control of curing speed ensures simultaneous surface drying and complete drying.
• Universal substrate compatibility: Whether it's precision electronic casings or high-end wooden furniture, it will not warp or yellow due to heat.

Against the backdrop of the nation's pursuit of "dual carbon" goals and enterprises' efforts to reduce costs and increase efficiency, handheld UV curing lamps are no longer merely auxiliary tools, but a strategic choice for coating workshops to move towards refined management. This proves that more environmentally friendly solutions are often also more efficient.

With the continuous optimization of UV paint formulations and further improvements in LED efficiency, we have reason to believe that the coating industry will completely bid farewell to the era of high energy consumption and enter a new stage that is lighter, greener, and more intelligent.
