Why are Fluorescent lights more efficient than incadescent bulbs?

Question

i already know that they are
just like.. how so?
i know they use less energy, but what about their chemistry does this?
Like, i'm talking about specifics, like electrons and atoms and how all that works to make it efficient

Answer 1

The incandescent light bulb is a tungsten fillament in an evacuated glass chamber. The electric current heats the fillament at a rate equivalent to the power consumption of the bulb. A 100 W bulb generates more heat than a 40 W bulb. The heating of the tunsten reaches temperatures sufficient for the metal to emit energy in a broad spectrum from infrared to some UV as the atoms of the metal are excited by heat energy. Some of the energy is emitted in the visible range, thus it provides light

The central element in a fluorescent lamp is a sealed glass tube. The tube contains a small bit of mercury and an inert gas, typically argon, kept under very low pressure. The tube also contains a phosphor powder, coated along the inside of the glass. The tube has two electrodes, one at each end, which are wired to an electrical circuit. The electrical circuit is hooked up to an alternating current (AC) supply

When you turn the lamp on, the current flows through the electrical circuit to the electrodes. There is a considerable voltage across the electrodes, so electrons will migrate through the gas from one end of the tube to the other. This energy changes some of the mercury in the tube from a liquid to a gas. As electrons and charged atoms move through the tube, some of them will collide with the gaseous mercury atoms. These collisions excite the atoms, bumping electrons up to higher energy levels. When the electrons return to their original energy level, they release light photons.

Incandescent bulbs artwork via forcing fairly a lot of electrical energy by way of a cord made up of tungsten. This motives the cord to become so warm that it glows white. regrettably, those easy bulbs produce an invaluable style of warmth, it somewhat is wasted power. This makes them inefficient. Fluorescent easy bulbs use electrical energy passing by way of fluorine and gaseous mercury with a view to produce an rather remarkable easy. They produce lots much less warmth than incandescent bulbs. in actuality, they or lots greater powerful, which you additionally may lead them to burn lots brighter with no need to apply as lots electrical energy. because of the fact of this incandescent easy bulbs use greater electrical energy for comparable quantities of light. better of success, -Fox
