How are fluorescent light bulbs made
Did you know?
Nikola Tesla made similar experiments in the 1890s, devising high-frequency powered fluorescent bulbs that gave a bright greenish light, but as with Edison's devices, no commercial success was achieved. One of Edison's former employees created a gas-discharge lamp that achieved a measure of commercial success. Ver mais A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave Ver mais The fundamental mechanism for the conversion of electrical energy to light is the emission of a photon when an electron in a mercury atom … Ver mais Fluorescent lamps come in many shapes and sizes. The compact fluorescent lamp (CFL) is becoming more popular. Many compact fluorescent … Ver mais Luminous efficacy Fluorescent lamps convert more of the input power to visible light than incandescent lamps.
