How do compact fluorescent bulbs work?

How do compact fluorescent bulbs work?

How Do CFLs Work? In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible light.

Do compact fluorescent bulbs need a ballast?

All fluorescent bulbs require a ballast. All compact fluorescent (CFL) bulbs require a ballast, which is often integrated. All HID bulbs require a ballast, which is sometimes integrated. No LED bulbs require a ballast, although some are engineered to work with an existing ballast.

What are the different types of compact fluorescent lamp?

8 Types of CFL Light Blubs

• #1 – Spiral CFL Bulbs.
• #2 – Incandescent Shaped CFL Bulbs.
• #3 – Globe CFL Bulbs.
• #4 – Tube CFL Bulbs.
• #5 – Candle-Shaped CFL Bulbs.
• #6 – Circular CFL Bulbs.
• #7 – Post CFL Bulbs.
• #8 – Reflector CFL Bulbs.

How do fluorescent and compact fluorescent lamps differ?

Standard fluorescent lights are available in tubes (generally 48 to 84 inches in length). CFLs are much smaller. They are still tubes but they are, as the name implies, “compact.” CFLs were designed to replace standard applications for incandescent bulbs as they are both more efficient and longer lasting.

Are compact fluorescent bulbs being phased out?

Now CFLs, or compact fluorescent lamps, are slowly disappearing from stores. Home retailer IKEA stopped selling them in all its locations last year, and now manufacturer GE has penned a cheeky Dear John letter to the technology, saying it will stop making the bulbs in the United States.

Why CFL is banned?

Like all fluorescent lamps, CFLs contain toxic mercury which complicates their disposal. In many countries, governments have banned the disposal of CFLs together with regular garbage. CFLs radiate a spectral power distribution that is different from that of incandescent lamps.

Which is better CFL or LED?

Efficiency—While incandescent bulbs and CFLs generate most of their energy in heat, LEDs are cool to the touch—which translates into less wasted energy. LEDs are more efficient than even CFLs: A 16.5-watt LED bulb is equivalent to a 20-watt CFL and a 75-watt incandescent.

What are the advantages of compact fluorescent lamps?

The advantages of compact fluorescents are they are energy efficient, compact in size, have good lumen maintenance, long life, endless shapes and sizes, dimmable, easy retrofit, low operating cost, and radiate less heat. Compact Fluorescent bulbs are about 4 times as efficient as incandescent bulbs.

How does a compact fluorescent lamp ( CFL ) work?

Like all fluorescent lamps, CFLs contain mercury, which makes their disposal complicated. CFLs work much like standard fluorescent lamps. They consist of two components: a gas-filled tube, and magnetic or electronic ballast. The gas in the tube glows with ultraviolet light when switched ON and electric current from the ballast flows through it.

How are compact fluorescent lamps different from incandescent bulbs?

Compact Fluorescent Lamps (CFLs) are a low energy alternative to traditional incandescent bulbs. Instead of a tungsten filament, CFLs consist of a glass tube filled with mercury vapour and gas, with an electrode at either end of the tube.

What’s the difference between CFL and non-integrated ballast?

A non-integrated ballast is the type of CFL technology that we typically call a “plug-in.” This means you will purchase the ballast separate from the lamp and the ballast will be configured in the fixture. This is similar to linear fluorescents but is far smaller than a linear ballast.

When did compact fluorescent light bulbs come out?

Everything that is going on inside the linear tube is still happening inside the compact fluorescent tube. Though linear fluorescents were first invented in the early 1900s, the CFL advancement didn’t come until around 1960. Why did it take so long to figure this out?
