What is tube light

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.

Which is the tube light?

The tube light is the fluorescent lamp. The tube light or the lamp is a low pressure, mercury vapour gas discharge lamp that works on the principle of fluorescence to produce visible light. When the power button is switched on, the electric current passes through the tube.

What is tube light made of?

A fluorescent lamp consists of a glass tube filled with a mixture of argon and mercury vapour. Metal electrodes at each end are coated with an alkaline earth oxide that gives off electrons easily. When current flows through the gas between the electrodes, the gas is ionized and emits ultraviolet radiation.

Which gas is used in Tubelight?

A fluorescent lamp tube is filled with agas containing low-pressure mercury vapor and argon, xenon, neon, or krypton (inert gases). The pressure inside the lamp is around 0.3%(very low) of atmospheric pressure.

Why tube light is white?

However, since ultraviolet rays are not visible to the human eyes, the inside of the glass tube is coated with a fluorescent material that converts ultraviolet rays to visible light. It is this coating that causes fluorescent lamps to glow white.

Are tube lights LED?

This tube light is mercury-free, which makes it environmental friendly as it consumes less energy. Eveready LED Batten comes with optimum functionality at Pocket-Friendly rates. The LED tube consumes less energy and hence saves more cost. This tube light produces light that perfectly suits your surroundings.

What are the 4 types of light bulbs?

What Are the Different Types of Light Bulbs?

Incandescent Bulbs. Source. Traditional incandescent light bulbs are still widely used but they're controversial due to their lack of efficiency.
Halogen Bulbs. Source. ...
Compact Fluorescent Lamps (CFLs) Source. ...
Light-Emitting Diode (LED) Source.

Which Tubelight is best?

An LED light produces 90% more efficient light as compared to incandescent bulbs and Compact Fluorescent Lighting (CFL) tube lights.

Why mercury is used in tube light?

When electricity enters a CFL, mercury and argon fumes inside the bulb produce invisible ultraviolet (UV) light. This UV light reacts with the fluorescent coating to produce the white, visible light you see when you turn on a CFL.

How does a LED tube light work?

An LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence.

Why inductor is used in tube light?

An inductor is used because unlike a resistor, a choke coil does not dissipate energy in the form of heat when current passes through it. A choke coil has inductive reactance which does not cause energy dissipation. It is also much easier to control AC mains using inductors such as the choke coil.

What happens when Tubelight breaks?

When broken, mercury vapors may be released into the air. The mercury released from broken bulb is mostly in vapor form. If properly cleaned up, broken bulbs or CFLs do not pose a serious health risk.

Which gas is filled in CFL?

CFLs instead send electric current through a tube (Figure 1) filled mostly with argon gas, and a slight amount of mercury gas. These gases generate ultraviolet light, which excites atoms on the phosphorous coating of the tube, which in turn emits visible light.

Does Tubelight contain mercury?

Really, these lights contain mercury? Yes, mercury vapor is used to transport electrical currents through the light bulb. Even though the amount of mercury is relatively small, fluorescent lights must be disposed of as hazardous waste.

Who invented Tubelight?

Edmund Germer Fluorescent lamp / Inventor Edmund Germer was a German inventor, recognized as the father of the fluorescent lamp. His father was an accountant. He obtained a doctorate from the University of Berlin in lighting technology. Wikipedia

Is Tubelight white light?

The light produced by a tube light is white in color. In a tube light, there is a filled with mercury at low pressure and when we apply a high voltage at the metal electrodes at the ends of the tube light the current ionizes the mercury vapor which emits ultraviolet light.

How does the tube work physics?

Process of tube light The heat makes the bimetallic poles in the starter bend towards each other. Once the bimetallic poles meet, the discharge automatically stops and is sent to the poles of the lamp. When the bimetallic strip cools, it returns to its original position.

Which is better Tubelight or LED?

LED tube lighting is the better choice because it lasts about 40,000 hours longer in testing, is more energy efficient, will save you more money, and will leave less impact on the environment.

Which is better Tubelight or LED for eyes?

Light emitted from tube light is pleasant: Tube lights will not hurt eyes when stared at it. It also causes less strain to the eyes when used for studying or working for a long time. Whereas, light emitted from CFLs and LEDs is harsh on eyes.
