LED LIGHT VS FLUORESCENT TUBE LIGHT

Hello folks!!!!!! I know it's been several years i haven't update anything and gone like that Cause get really busy with studies,exams,works and so on. I'm apologize for not updating you guys for give awesome information about and it's not too late. I'm Back now. Now to topics is LED tube light Vs Fluorescent tube light.

In recent years,LED becomes pop star among light variety,people began to change their home lights into LED light and throw away their old rusty fluorescent lights. What so special about these LED light that keep people attract to it, Lets find Out.


Now lets look about the good old fluorescent light specification and design.

There's already post about the fluorescent light and the wiring detail and here's the link: https://electrical4dummies.blogspot.com/2016/04/how-to-wire-fluorescent-tube-light.html.
So in this fluorescent light design,got ballast or auto transformer which give high voltage to starter to flick the light to open and glow. This means the light works in high voltage condition. Even it's work in high voltage condition there's benefits and some drawbacks.

Advantage

1.Can last longer than LED light
2.Parts easily can be change
3.Can fix in flat and rough surface.

Disadvantage

1.Complex wiring circuit,requires skill technician to do it
2.Cables get burns by overheating ballast that occur when light ON for long duration
3.Very hard to find the source of the problems when light didn't work properly.
4.Tube light glass easily broken and harmful poison gas release from it.
5.More power consumption
6.More parts require for light installation
7.No energy efficient

In some cases,you can smell the cables burns and trip the circuit breaker when the cable gets damaged. That's the reason some fluorescent light get spoiled quickly draws more power comsuption. The solution for this problems is place a thermal insulation for cable which sits beside the ballast for protect the cable get heat.

Here comes the LED light which is simple and easy to install and the wiring is easy than the fluorescent light. But it also have some benefits and drawbacks too.

 Advantage

1.Simple installation
2.Easy wiring (Depends On Light Design)
3.Built in mini AC-DC converter
4.No harm to people by broken light glass.
5.Comes with dimmable or non- dimmable
6.Less power comsuption
7.More Brighter
8.Less parts needed for light installation
9.Energy efficient

Disadvantage

1.Light works in Hours rate
2.Tube light easily will break

On thing if you notice in LED tube light label is the hour rate and the luminosity. LED tube light comes with various types of design and models,so every LED light specification is different.

Lets take this model for an example, 15000 Hrs is the life span for the light. The K unit is stand for Kelvin is the unit of temperature. Which refers to light temperature gives out the desire light color. When light comes closer to 150000 hrs, you will see the light will flicker or it will turn into purplish color which indicate the light going to die soon and need to change new one.

Finally this is the reason why LED tube light is become people champion although Fluorescent tube still excellent in some purpose. But still fluorescent light use in UV lights, Hi Beam Mercury light, Rooftop spot light and so on.

ELECTRIFYING FACT OF THE DAY

DON'T THROW FLUORESCENT TUBE LIGHT CAUSE YOU STILL CAN USE THE CAPACITOR IF INSTALL AND BALLAST FOR OTHER PROJECTS AND APPLICATION. ALSO CAN SELL TO SCRAP AND EARN SOME BUCKS :P

What happen when short circuit happen in electrical outlet and appliance

Every time you use your electrical outlet that connected to electrical appliance and it works good. But suddenly a sparks created in the electrical appliance and get burn or explode. The MCB that connected to the electrical outlet trip. So What the heck happens? Well dummies if you read my previous post (Fault in Electrical Circuit) You probably know that is short circuit. The questions is what happen when a short circuit get in electrical outlet and appliance? Lets find out.

Short circuit is an electrical circuit fault,when different current carrying conductors contact each other. Like Neutral wire contact Live. When this happen you MCB will instantly trip in order to protect your electrical appliance and rid you from getting shock.  

When you look into further, When a live wire bypass to neutral accidentally, the current will increase and the voltage will be near zero. This is because the conductor of both wire is less resistance. This is why current increase in first place. The reason why voltage becomes zero is as we know voltage is a electrical potential. When the conductors bypass another conductor, the voltage will choose the less resistance path that make the voltage zero.

Using Ohm's Law you can also see when the resistance is 0 The voltage is zero too. So the current will get higher. When short circuit occur a huge sparkles with arcs. This is dangerous to human when comes to contact with it. even contact with water is so dangerous. 

There's some benefits from short circuit that people used to do everyday like welding. Grounding the metal with ground cable and hold live wire with welding electrode. when the electrode touch the ground,it will make sparks and arc to melt the electrode and stick to the metal. 

There's also a dangerous thing about short circuit. It cause you to pass out or second degree burn on you. So stay away when short circuit happens. Short circuit even happen in DC also. Like in electronics,if the components didn't solder rightly, the component might pin will touch other component to make short circuit.

 In Overhead transmission line also can be short circuit if the distance between the cable is so closely. 

FOLKS YOU HAVE TOO BE ALWAYS AWARE OF ELECTRICAL ACCIDENTS. IT MAY HAPPEN ANYTIME. ALL YOU NEED TO DO IS MAKE YOURSELF SAFE. SAFETY FIRST.

Electromagnetism : Three phase Motor

Factories!!!! Conveyor belt machines!!!! Mixer!!!. These three things has something one in common. That is really fascinating us to know what is the common thing. Let me give you clues. These three things usually used in factories and some used in homes to. It rotate all time depends on user and it's cheap. Well dummies if you guess three phase induction motor, and you are right. Dummies lets learn about three phase induction motor that going to amaze your mind.

The picture above shown is the exploded view of three phase induction motor. The main two parts of AC three phase induction motor is the stator and Rotor.The stator is the stationary part and the function as you know earlier that produce rotating magnetic field. The rotor is the rotating part. The rotor is a squirrel cage design that short circuit in end rings. These will allow rotor to rotate by inducing magnetic field in rotor.

Lets go to the interesting part. It's the working principle of Three phase motor.  If you compare single phase induction motor, you can easily spot the difference in three phase motor. Like in three phase motor has Three phase windings. Means each phase has it's own windings. When the three phase supply flows to the each stator windings and it will energize. The energize each phase windings will give a rotationg magnetic field that runs  at synchronous speed. To calculate the synchronous speed the formula is : 

While the rotating magnetic field runs in synchronous speed, the rotating magnetic field will energize the rotor. This will produce and EMF in the rotor and produce a force to rotate the rotor by Lorentz's force law. This rotation will make a three phase sinusoidal wave. This means each phase has it'a own sinusoidal wave in order to rotate the rotor.

It's look interesting to see how this three phase motor works. But there's a little glitch in the rotor. Like in synchronous motor, the rotor with permanent magnet or external DC power supply, will follow the stator rotating magnetic field in constant synchronous speed even load is added. But in this induction motor, The rotor first follow the synchronous speed. Eventually the when the both stator's rotating magnetic field and rotor comes with same speed, it will slow down and speed up again. This rotor speed never achieve the synchronous speed. This phenomena called 'Slip' Note that dummies. To calculate the slip the formula is :

Every things has benefits and some drawbacks. Same goes to this induction motor dummies. The advantage is less maintenance and less cost. this is why it's widely used in factories. Furthermore, it also has self starting that doesn't require external force or adding special windings.

 The disadvantage of this induction motor is it produce huge amount of heat actually can fried an egg :P just kidding,There's a fan mount back of the motor to dissipate the heat. The torque is reduce when load is added and didn't make constant synchronous speed. Finally it has less efficiency than a synchronous motor.

 IT BEEN 8 MONTHS I START THIS BLOG AND GAIN 3K VIEWS. I THANK YOU TO PEOPLE FROM ALL OVER THE WORLD WHO READ THIS BLOG AND UNDERSTAND THE WORLD OF ELECTRICITY. SHARE THIS BLOG AND CONTACT ME OR EMAIL ME TO DISCUSS OR TALK ABOUT ELECTRICAL TOPICS. 
TILL THEN STAY ELECTRIFY

The Lorentz Force Law

We seen how magnetic field behaves when interact with conductor, as today we know motors. What makes a motor rotate by itself without starting by external force? This kind of question commonly everyone has. Well dummies it's all about Lorentz force. So lets discuss about Lorentz force law.

Lorentz force Law says When a electric charge Q flows in a magnetic field B,The force occur in both the direction of magnetic field and charge are perpendicular. 

  
This is easily determined by Right Hand rule and Right hand Fleming's rule too. The right hand rule indicate the thumb as the direction of current flows and other 5 fingers refer to the direction of magnetic field. While in Fleming's right hand rule state is force is perpendicular to the direction of current flows and the direction of magnetic field.

This force created by electric charge such as electron flows in a conductor that exert in magnetic field. When the electron moves in the magnetic field, it feels a force that might the force goes upward or downward. This force cannot be don't if the electron move parallel to the magnetic field. This is because the force will be zero if move parallel to the magnetic field. The equation for this will be :

Applications Of Lorentz's Force Law

1. Electric Motors

 

Electric motors are run by this force. Example your toy car DC motor. When the conductor in rotor by external DC power supply, the rotor will rotate.

 

2.Northern Lights (Aurora)

 

When solar charge particles hit the earth magnetosphere (Earth's Magnetic Field),The particle will spiral along with earth's magnetic field and get the beautiful northern light.

 

3.Speaker   

 

When a speaker's coil is energize it's vibrate the diaphragm with the permanent magnet due to the Lorentz force generate in the coil,
