      Nail curing lamp is an important tool for curing nail polish. Currently, the most commonly used nail lamps are UV lamps, LED lamps and CCFL lamps. What is the difference between different lights?
      The UV nail lamp is an abbreviation for the ultraviolet lamp. The UV nail lamp is a hot cathode fluorescent lamp, and its lamp emits UVA, which corresponds to a nail polish containing a UV-reactive photopolymerization initiator.

      LED is an abbreviation for light-emitting diode, which can directly convert electricity into light. The LED is a single-wavelength light source, so it can be used in combination with ultraviolet or infrared light. So we can see that there are UV+LED dual lamps on the market.

      The CCFL lamp is called cold cathode fluorescent tube, which has the advantages of high power, high brightness and low energy consumption. Moreover, the life of the cold cathode is relatively long, so it is not necessary to replace the bulb.
      There are some common problems with nail lamps:
      1: Does the nail lamp tan skin like UV lamps?
      The ultraviolet light emitted by the nail UV lamp belongs to the UVA band, that is, the wavelength is 320 to 400 nm, which is also called the long-wave black spot effect ultraviolet light. It does not contain UVB and UVC bands. UVB is outdoor ultraviolet light. UVB that is not absorbed by the ozone layer will illuminate the surface of the earth. People will directly inject into the skin when they are outdoors. The damage caused by it is short-term and immediate. (UVC as a short-wave UV lamp will be absorbed by the ozone layer and can be ignored).
      The UVA band of light requires a long period of chronic exposure to organically cause harm to human skin. The general power of current UV nail lamp is between 20-30W, and some LED lights emit less power 9W. According to the frequency of making nails in two weeks, the exposure dose and irradiation time of these UVA bands are far from being able to tan or cause disease.
      2: Does the UV lamp need to be replaced? How often do you change it?
      The intensity of the UV lamp will gradually decrease, so the lamp needs to be replaced regularly. After the lamp has been used for a period of time, the intensity of the emitted UV light is weakened, so some nail lamp manufacturers use an
UV light meter to measure the intensity of the nail lamp.
      3: Which type of lamp is better for nail lamps?
      The exposure time of the nail lamp is not enough to tan the skin, but the LED lamp emits UVA (long-term use) which causes the skin to have melanin precipitation, just like the ordinary UV lamp, but compared with the UV lamp, the LED lamp only needs to be irradiated very short. So the LED lamp is more energy efficient than the UV nail lamp. But the corresponding price is also more expensive than the UV lamp. 
      Furthermore, the LED light does not emit light in other wavelength bands, and it will not be hot when illuminated, and will not burn the hands and feet. At present, the new phototherapy lamp is a UV lamp + LED lamp, which has the advantages of long service life, low power, low heat generation, more stable ultraviolet source and stronger penetrating power.
      4: How long does it take for a general nail lamp to reach the effect of curing the nail polish?
      As mentioned above, different nail lamps have different power levels, LED lamps are single-wavelength light sources, and UV lamps are not a single wavelength, and the illumination durations required for the two lamps are different. So the specific illumination duration is determined by the power and type of the lamp.
