What sort of spectrum would the light from a fluorescent light or compact fluorescent bulb produce?
Fluorescent lights produce primarily UV radiation. They generate visible light because the bulb is coated with a layer of phosphor which glows when it comes into contact with UV radiation. Although most UV radiation stays within the bulb, some does escape into the environment which can potentially be a hazard.
What do the markings on fluorescent tubes mean?
Lamps are typically identified by a code such as FxxTy, where F is for fluorescent, the first number (xx) indicates either the power in watts or length in inches, the T indicates that the shape of the bulb is tubular, and the last number (y) is the diameter in eighths of an inch (sometimes in millimeters, rounded-up to …
What is the spectrum of fluorescent light?
The spectrum of a fluorescent light has bright lines and a continuous spectrum. The bright lines come from mercury gas inside the tube while the continuous spectrum comes from the phosphor coating lining the interior of the tube.
What are the effects of compact fluorescent lights?
Doctors at Stony Brook University in New York found that CFL bulbs produce significant levels of UVA and UVC emissions, which are harmful to human skin. This ultraviolet radiation can cause skin to age and burn and ultimately lead to skin cancer.
How do fluorescent tubes work physics?
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 ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow.
How is the fluorescent light spectrum different than the spectrum of daylight or tungsten?
a fluorescent bulb has to do with light spectrums and light wavelength. Fluorescent light wavelengths are shorter than incandescent light wavelengths and deliver a different kind of light to the eye. Fluorescent light is on what is called an emissions spectrum. This means that its wavelengths are punctuated by lines.
What is the difference between T8 and G13?
A T8 tube is also called a TL-D tube from Philips and a Lumilux tube from Osram. You can recognize a T8 tube from it’s 28mm diameter. The socket is called G13 this because the 2 pins are 13mm apart from each other. . A T8 tube can work on an electronical ballast using a fixture without a starter.
What do the numbers and letters mean on fluorescent bulbs?
Fluorescent tube shape Linear fluorescent lamps typically include a “T” in the shape abbreviation with a number following it. This “T” stands for tube and the number that follows is the diameter of the tube. That number is divided into 8 to translate into inches. So a T8 has a one inch diameter.
How fluorescent and compact fluorescent bulbs work describe how their operations and their spectra differ from those of incandescent light bulbs?
An incandescent bulb is on what’s called a continuous spectrum. This means that all visible colors are present. In contrast to a fluorescent light spectrum, which only produces a limited amount of color, the incandescent light spectrum is more dynamic.
What are the benefits of using compact fluorescent light bulbs?
Because CFLs use less electricity than traditional light bulbs, they reduce demand for electricity; that reduction means less greenhouse gas emissions (including less mercury) from power plants. CFLs contain a very small amount of mercury — an average of 4 milligrams in each bulb.
