What is the purpose of fluorescent lamp?

Fluorescent lamps are a lamp type that is commonly used to provide illumination for settings such as commercial lighting, industrial lighting, classroom lighting, and retail lighting. The sizes, light colors, and wattage of fluorescent tubes vary significantly.

How does a fluorescent light bulb work for kids?

How it works. An electric current is applied to mercury vapor inside the tube, causing it to emit ultraviolet (UV) light. A phosphor on the walls of the tube absorbs the ultraviolet light. This causes an electron to jump up to an orbital with a higher energy.

What does a fluorescent lamp require?

Fluorescent lighting depends on a chemical reaction inside of a glass tube to create light. This chemical reaction involves gases and mercury vapor interacting, which produces an invisible UV light.

Do fluorescent lights emit UV?

All fluorescent lamps emit some UV. Typical fluorescent lamps, including CFLs, which consumers would encounter, emit very low levels of UV. In order to measure any UV radiation from these lamps, very sensitive measuring equipment must be used.

What is fluorescent lamp wiring?

When we connect the AC supply voltage to the circuit, then the starter act like short circuited and current flow through those filament (located at the first and second end of the tube light) and the filament generate heat and it ionized the gas (mercury vapor) in the fluorescent tube lamp.

Can you get sunburn from fluorescent light?

In other words, there aren’t any known cases of sunburn from light bulbs yet. As it turns out, all fluorescent light bulbs contain mercury vapor, which emits a lot of UV rays when hit with an electric current.

Is fluorescent light the same as sunlight?

Like sunlight, fluorescent light is also white light, and it is also made up of many different wavelengths. But, the wavelengths in fluorescent light are not exactly the same as those in sunlight. Makeup that looks wonderful under fluorescent light will look strange under natural light.

How do fluorescent light bulbs help the environment?

Fluorescent light bulbs consume less energy and heat per hour than regular bulbs. The energy output is much more efficient for people looking to conserve the environment. Traditional bulbs produce energy, but lose up to 80 percent of it in the process.

How do fluorescent lamps work in a circuit?

The classic fluorescent lamp design, which has fallen mostly by the wayside, used a special starter switch mechanism to light up the tube. You can see how this system works in the diagram below. When the lamp first turns on, the path of least resistance is through the bypass circuit , and across the starter switch. In this circuit, the current passes through the electrodes on both ends of the tube.

What is inside a fluorescent lamp?

A fluorescent lamp basically consists of a long glass gas discharge tube. Its inner surface is coated with phosphorous and is filled with an inert gas, generally argon, with a trace of mercury.

How do fluorescent light bulbs save energy?

How compact fluorescent lamps ( CFLs ) work. Traditionally, energy-saving lights save energy by making light without the heat using a completely different process called fluorescence. This is a trick similar to the one used by creatures like fireflies and glow-worms, whose bodies contain chemicals that make “cool light” without any heat.
