Spectrum of fluorescent light
Did you know?
The spectrum is nearly identical to a normal fluorescent lamp except for a near total lack of light shorter than 500 nanometers. This effect can be achieved through either specialized phosphor use or more commonly by the use of a simple yellow light filter. See more 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 See more The fundamental mechanism for the conversion of electrical energy to light is the emission of a photon when an electron in a mercury atom falls from an excited state into a lower energy level. Electrons flowing in the arc collide with the mercury atoms. If the … See more Fluorescent lamps come in many shapes and sizes. The compact fluorescent lamp (CFL) is becoming more popular.

When you switch on the lamp the gas starts emitting light. However in contrast to the sodium lamps which are widely used in street lighting (the orange lamps), mercury emits UV light (mainly 254 nm) which is not only invisible for us, but could also harm us in the same way UV light from the sun can …
WebAug 29, 2024 · Fluorescent Light Wavelength Spectrum . Fluorescent lights are a type of light that use electricity to produce light. These lights contain a gas that is excited by the electric current and then emits ultraviolet (UV) light. This UV light then strikes a phosphor coating inside the tube, which converts the UV light into visible light.
