In recent years, the popularity of nail art has spurred innovations and technological advancements in the nail industry. If you frequently get your nails done, you might already know that the best gel nails today have evolved from traditional nail polish. Along with this evolution, UV nail lamps and LED nail lamps have emerged. So, how do UV LED nail lamps work? How do they work? Let’s unveil the answers to these questions for you.

Gel Nail Polish Curing Principles

As mentioned above, nail lamps emerged as a response to the evolution of nail polishes. Now, let’s delve into the principles of gel nail polish curing.

The photoinitiators (or photosensitizers) in gel nail polish absorb ultraviolet light when exposed to UV light, generating active free radicals or cations, initiating monomer polymerization, cross-linking, and branching chemical reactions, which transform the adhesive from a liquid to a solid state within a few seconds. Typically, gel nail polish can only absorb specific wavelengths of light, so different wavelengths correspond to different gel nail polishes; the selected nail lamp must be able to produce ultraviolet light within this wavelength range to be effective.

Nail Lamp Categories

1. Nail Dryer

Nail Dryers are devices used to quickly dry traditional nail polish. They may use fans or warm air to accelerate the drying process of nail polish, but do not involve any UV or LED light curing technology. They are similar to hand dryers found outside restrooms and have almost been phased out in the nail industry.

2. UV Nail Lamp

UV Nail Lamps use ultraviolet light to cure specific formulations of gel nail polish. They typically contain mercury-filled tubes, which, when an electric current passes through, produce UV light to activate the photoinitiators in the gel nail polish, thereby achieving curing. UV nail lamps usually emit light within the UV-A spectrum range, with wavelengths typically between 320 to 400 nm. Some common specific wavelengths might include 365 nm, 375 nm, 385 nm, or 395 nm.

3. LED Nail Lamp

LED Nail Lamps utilize LED (Light Emitting Diode) chips to produce a specific range of wavelengths to cure gel nail polish. They are usually more energy-efficient, cure faster, and have a longer lifespan. LED nail lamps typically emit light close to the ultraviolet or visible light range, with wavelengths usually between 365 to 420 nm. For instance, they might emit light at 365 nm, 385 nm, 395 nm, or 405 nm.

4. UV LED Nail Lamp

UV LED Nail Lamps combine UV and LED technology, capable of emitting light within both ultraviolet and visible light wavelength ranges. This design allows UV LED nail lamps to be compatible with various types of gel nail polish, providing users with an efficient and flexible curing solution. Common UV LED lamps on the market may have peak wavelengths at 365 nm, 385 nm, 395 nm, or 405 nm, meaning the light intensity is highest at these specific wavelengths; while most of IKSBEAUTY’s UV LED lamps have peaks at 365 nm and 405 nm, and of course, we can also customize according to your needs.

Nail Lamp Light Emission Principles

1. UV Nail Lamp: Traditional UV nail lamps usually rely on mercury gas discharge to produce ultraviolet light. Their design may include electronic control systems and circuit boards, which may have chips to control the current and other functions of the lamp. However, the generation of UV light mainly relies on the mercury gas discharge in the tubes, not semiconductor chips.

2. LED Nail Lamp: The core component of LED nail lamps is the LED (Light Emitting Diode) chip. These chips are semiconductor devices that produce light when current passes through them. Each LED chip is designed to emit light within a specific wavelength range, usually in the visible light or near-ultraviolet range.

3. UV LED Nail Lamp: This type of nail lamp uses specially designed LED chips to produce ultraviolet light. Similar to regular LED nail lamps, their core component is the LED chip capable of emitting light within the ultraviolet wavelength range.

  • How To Use UV LED Lamps?
    Just like you have used UV or LED nail lamps before, turn on the power, and select the curing time based on the thickness of the gel polish you applied. If you applied a thicker layer, choose 45 seconds or more; if you applied a thinner layer, choose 30 seconds or less. Of course, curing time is also affected by other factors, which you can read about in our other article: How Long to Cure Gel Polish Under UV Light?
  • How to maintain and clean your UV LED nail lamp?
    Keep the lamp clean, especially avoid dust and gel residue accumulation on the light beads. Regularly use a soft cloth and non-corrosive cleaner to gently wipe.
  • What is the lifespan of UV LED nail lamps?
    UV LED nail lamps usually have a long lifespan, typically over 50,000 hours.
