Achieving an impressive lifespan of 60,000 hours! A lighting system combined with a dedicated inverter.

We will introduce the principles and structure of the "electrode-less lamp" that our company handles. Since it adopts a mechanism based on the principles of electromagnetic induction and discharge light emission, the lamp itself is not affected by factors such as electrode wear, allowing it to light up semi-permanently. By passing high-frequency current through a coil, a magnetic field is generated in the ferrite core, which in turn creates an electric field inside the lamp. Electrons released in this electric field collide with mercury particles, emitting ultraviolet light, which is then converted into visible light by the phosphor coated on the inner wall of the lamp tube. 【Features】 ■ No filament ■ No electrode wear compared to conventional fluorescent lamps ■ Achieves an impressive lifespan of 60,000 hours ■ Lighting system combined with a dedicated inverter ■ Instant lighting and instant re-lighting are easily possible *For more details, please refer to the PDF document or feel free to contact us.

basic information

【Other Features】 ■ Similar to conventional fluorescent lamps, a glass tube coated with phosphor contains rare gas and a small amount of mercury sealed as an amalgam. ■ By adopting a special coating, the degradation of the phosphor is significantly reduced compared to conventional fluorescent lamps, achieving a high maintenance rate of luminous flux over long periods. ■ By using amalgam, the design ensures that luminous flux does not decrease even when the temperature inside the fixture rises, compared to standard fluorescent lamps that use pure mercury. ■ By employing a three-wavelength phosphor, the average color rendering index is Ra80, providing high color rendering to keep the illuminated space comfortable. *For more details, please refer to the PDF document or feel free to contact us.
