<p>As the mainstream lighting equipment, <a href="https://www.cowlightbulbs.com/led-filament-bulb" rel="noopener noreferrer" target="_blank"><strong>LED filament bulb</strong></a>s are basically available in every household. Many people are curious about how LED filament lamps emit light. Therefore, today I will give you a popular science about the principle of LED filament bulbs. It will satisfy everyone's curiosity and give everyone Popularize the knowledge of LED filament bulbs.</p><p><br></p><p>First of all, if the temperature is too high, the filament is easily oxidized in the air, so the LED filament bulb must be isolated from the air to work, that is, the bulb can be vacuumed or filled with inert gas such as nitrogen that does not react with the filament. Generally speaking, the bulb power of 40W and below is a vacuum LED filament bulb, and the power of 40W and above is a gas-filled bulb.</p><p><br></p><p>Secondly, the LED filament lamp is made according to the principle of thermal radiation. It relies on current to heat the filament to incandescent temperature, and the light source that radiates visible light. The filament is the main part of the LED filament bulb. If the filament is broken, the bulb will be broken.</p><p><br></p><p>Furthermore, the filling gas of the LED filament lamp is a mixed gas of argon and nitrogen. The purpose of charging in the LED filament bulb is to reduce the evaporation of tungsten. Because tungsten encounters inert gas obstruction during the evaporation process, some tungsten particles will fold back to the filament. In this way, the evaporation of tungsten can be reduced, and the working temperature of the filament can be increased accordingly, the luminous efficacy of the LED filament bulb can be improved, and the life of the LED filament bulb can be prolonged.</p><p><br></p><p>After reading the above content, everyone must have understood the principle of LED filament bulb.
