Nikola Tesla's Incandescent Electric Light introduced an innovative improvement to high-frequency electric lighting by reducing energy losses inside the lamp. Instead of allowing high-frequency electrical energy to dissipate along the supporting conductor, Tesla surrounded it with a metallic electrostatic shielding tube, concentrating the electrical effects at the light-emitting refractory button. This design produced brighter illumination while improving the efficiency of high-voltage, high-frequency lighting systems.

The lamp consists of a highly evacuated glass globe containing a small refractory button mounted on a carbon support. A thin conducting wire supplies high-frequency electrical energy, while a metallic tube surrounds the supporting conductor, acting as an electrostatic screen. This shielding confines the electrical action to the exposed light-emitting button, minimizing unwanted energy dissipation and increasing luminous efficiency.

The CAD model illustrates the complete lamp assembly, including the vacuum glass envelope, supporting stem, conducting wire, carbon support, refractory light-emitting button, and the surrounding electrostatic shielding tube. The simulation demonstrates how the metallic screen directs the electric field toward the exposed button, producing efficient incandescence while reducing electrical losses within the lamp.
