Market Analysis of UVLED Industry Applications

UVLED is gradually entering our field of vision, and some companies are participating in the research, improvement, and application of UVLED ultraviolet lamps. For the general public, an appropriate amount of ultraviolet radiation of appropriate wavelength is also a necessary light wave for our human body. So today we will learn about the main applications of UVLED in which fields.

The so-called ultraviolet rays (UV) refer to the visible light of the sun (red, orange, yellow, green, blue, purple) that is invisible to the naked eye outside of purple. Ultraviolet is a general term for radiation in the electromagnetic spectrum with wavelengths ranging from 10nm to 400nm. According to different wavelengths, ultraviolet radiation is generally divided into three bands: A, B, and C. Specifically, UVA ranges from 400 to 315nm, UVB ranges from 315 to 280nm, and UVC ranges from 280 to 100nm. Corresponding to different wavelengths, specific applications may vary.

Compared to UV discharge lamps, UV LED has many advantages: more environmentally friendly, free of mercury, no environmental pollution, and no health risks; Long lifespan; Low radiation attenuation; Easy to control and adjust, etc. Therefore, UV LED has broad application prospects and can be used in many fields such as curing, detection, medical treatment, beauty, sterilization, disinfection, communication, etc.

Application areas in UV curing systems:

The typical applications of UVA band are UV curing and UV inkjet printing, with representative wavelengths of 365nm, 385nm, 395nm, and 405nm. UVLED curing applications include UV adhesive curing in industries such as display screens, electronic healthcare, and instruments; UV coating curing for industries such as building materials, furniture, household appliances, and automobiles; UV ink curing in industries such as printing and packaging... Among them, the UV LED decorative panel industry has become a hot topic. The biggest advantage is the ability to produce environmentally friendly boards with zero formaldehyde, which can save 90% energy, produce large quantities, be resistant to coin scratches, and have comprehensive economic benefits. This indicates that the UVLED solidification market is a comprehensive and full cycle application product market.

Microelectronics industry - UV curing applications: component assembly (camera lens, earpiece, microphone, shell, LCD module, touch screen coating, etc.), hard disk head assembly (gold wire fixation, bearings, coils, chip bonding, etc.), DVD/digital camera (lens, lens bonding, circuit board reinforcement), motor and component assembly (wire, coil fixation, coil end fixation, PTC/NTC component bonding, protection transformer core), Semiconductor chips (anti moisture protective coating, wafer mask, wafer contamination inspection, exposure of UV tape, wafer polishing inspection), sensor production (gas sensors, photoelectric sensors, fiber optic sensors, photoelectric encoders, etc.).

LED UV curing applications in the PCB industry: fixing components (capacitors, inductors, various plugins, screws, chips, etc.), moisture-proof sealing and core circuit and chip protection, antioxidant coating protection, circuit board conformal (corner) coating, ground wire, flying wire, coil fixing, wave soldering through-hole mask.
