do not worry. LED lights are recognized as cold light sources without radiation. compared to ordinary spotlights. Working under the LED light will not harm the skin.
- The first thing to tell you is that visible light is a kind of electromagnetic radiation. When it comes to radiation, everyone’s face has changed, it’s actually not that serious. LED lamps are semiconductor materials.
- The led light is actually a light-emitting diode, and its basic structure is an electroluminescent semiconductor material chip, fixed with silver glue or white glue, connected to the chip with silver or gold wire, and sealed with epoxy resin to protect the inner core wire , covering the shell.
The diode is semi-conductive, the positive voltage is turned on and the negative voltage is turned off, and it is controlled by DC voltage without electromagnetic radiation. The alternating current signal can generate alternating magnetic fields and the possibility of electromagnetic radiation. DC voltage control is used, so there is no electromagnetic radiation. Only with an alternating current signal can an alternating magnetic field be generated and the possibility of electromagnetic radiation be possible.
Generally speaking, LED judges factors such as the length of irradiation time according to the brightness of the lamp and whether the lamp damages the skin.
The details are as follows:
- No damage to the skin: LED lights have a certain amount of radiation. If used by asymptomatic patients, the brightness is not high. The irradiation time is not long, and generally there is no damage to the skin.
- Skin damage: However, long-term exposure to the skin will generally damage the skin to a certain extent, which may lead to changes in facial skin cells. If the light is not well adjusted, it may also stimulate the secretion of melanocytes in the skin, resulting in darkening of the skin.
In addition, LED lights can also be used for beauty, using the principle of photodynamics to activate deep cells and make the skin better metabolized.
