Lighting : Everything you need to know about Lighting

Introduction to the electric searchlight:

Flashlight:

The first electrical measuring instrument to detect the presence of an electrical charge,

Charge is detected by the movement of the body due to the electrostatic force according to Coulomb’s law.

The amount of charge on a body is proportional to its potential.

Charge buildup  to detect with an electroscope requires hundreds or thousands of volts,

Electromicroscopes are therefore used with high voltage sources such as static electricity and electrostatic machines.

Use an electric flashlight to demonstrate electrostatic induction.

The electroscope can only give a rough indication of the amount of charge;

An instrument that measures electric charge quantitatively is called an electrometer.

The first electric searchlight was a coaxial needle (called a versorium).

Invented by British physician William Gilbert around 1600, it is still used in physics education to prove the principles of static electricity.

A type of electroscope is also used in quartz fiber radiation dosimeter.

The torch usually consists of a pair of thin gold leaves suspended from an electrical conductor.

A transparent box that is isolated from its external surroundings so that what is inside it is not affected by what is around it.

Its working principle is based on repulsion and attraction of charges. This is done by bringing a charged body close to the column connected to the searchlight device.

Therefore, the electrons move on the body to which they are connected to the detector device, reaching the two thin gold leaves.

To protect the gold leaves from air currents, they are placed in a glass bottle, usually opened at the bottom and mounted on a conductive base.

There are often metal plates or foil strips in the bottle surrounding the gold leaf on both sides,

The charges are distributed equally on the two papers, which results in the presence of the same charges on both papers.

Modern electromicroscopes typically use balls made of plastic to test the presence of charge on an object.

The electric searchlight is considered one of the most important inventions through which several things were revealed in scientific studies.

What is the story of the invention of the electric searchlight?

Jean-Antoine Nollet was a cleric and physicist.

In 1748 AD,

Nollet invented one of the first electron meters, the electroscope, and determined the existence of an electric charge using the principle of attraction and repulsion.

Nollet later wrote a theory of electric attraction and repulsion based on the existence of a continuous flow of electrical matter between charged bodies and became the first professor of experimental physics at the University of Paris.

Scientists continued to make many improvements to the searchlight,

Because it only indicated the presence of the shipment and not its type, after that they modified it so that they could know the type of shipment as well.

Later, a graduated scale was added to determine the amount of charge. In the late nineteenth century, a detector was developed to study radioactivity.

Samuel C. Lind, born in 1879 AD, invented the first electric searchlight for radium measurements, called the Lind searchlight.

 Floodlights: Everything you need to know about Floodlights

Installation of lighting fixtures

One of the most cost-effective and quickest upgrades you can do to the appearance of your home is through

Easy and simple lighting upgrades, floodlight replacements and electrical upgrades that will make your home brighter and more inviting.

Most floodlights come with instructions that will help you assemble and install the light, which I recommend you read the manufacturer’s instructions before you start replacing the light fixture.

This step-by-step lighting installation will help you replace most downlights including sconce lights, pendant lighting, track lighting, ceiling light, wall light and more.

The following is a simple, easy, step-by-step procedure that will help you install the lighting fixture safely and correctly.

Most floodlights and light boxes are universal and standard,

So the lighting installation procedure you will learn here will help you be able to install most spotlights.

To make installing the light easier, it’s a good idea to take a photo of the old light’s wiring or even a video, especially when there is more than one three-conductor wire inside the box.

When installing a light fixture, the black/red wire is hot, the white wire is neutral and the bare wire is grounded.

Before doing anything, turn off the power and check the dual circuit with a non-contact voltage tester to ensure there is no power to the light.

Always turn off the power to the light you want to install or remove from the circuit breaker panel and if not the electrical panel

If your light is rated or you’re not sure what circuit is for the light you’re replacing, turn off the main breaker which will shut off power to your entire home.

Tools you need for light installation:

[Screwdrivers (4 in 1, or Philips, flat, Roberson), non-contact circuit tester, pliers, wire strippers, wire cutters, safety glasses

, ladder, flashlight, wire connectors (wire nuts)]

alert:

When working with electricity, caution and caution are the first priority and be sure to follow the electrical code and building code requirements,

And first check with your local electrical code authority if you are allowed to do this electrical job if you do not contact a licensed electrician.

If you’re not sure about your home’s wiring, hire a certified electrician. And always disconnect the power before doing anything.

How to replace headlights

1. Start by reading the manufacturer’s instructions and assembling the new light as best you can

2. Turn off the power from the electrical panel by flipping the breaker that powers the light fixture you are replacing

3. Make sure the power is off by turning the lamp off and on

4. Remove old headlights by removing the light bulbs, and the lamp shade

This is when you will see the current lighting wires and connections and use a non-contact voltage tester to ensure there is no power.

5. Take a picture of the existing wires to make sure you remember how to connect the wires and the new wires the same way.

This is especially useful when there is more than one three-conductor wire in the box

6. After ensuring that there is no power, disconnect the wires and remove the old headlights

7. Install the mounting bracket and hardware for the new lighting fixture on the ceiling light box

8. Connect the light wires to the wires in the box with the same colors (black to black, white to white, green to green or bare)

Pull each wire nut to make sure the connection is tight, then push the wires into the box.

9. Install the new light fixture on the mounting bracket, and install the new bulbs and lamp shade.

(note:

Be sure to check the light bulb rating and install bulbs with the maximum wattage at or below what is indicated on the light bulb)

10. Turn on the electricity by flipping the breaker and enjoy the new lighting

.

How to install a lighting device

Here are simple and easy techniques to install spotlights correctly and safely:

1. Start by reading the light manufacturer’s instructions on how to assemble and install the light fixture

4. Make sure the light box is securely fastened and supported properly if it is not secured and supported

5. Install the mounting bracket for the new light fixture and install it correctly

6. Connect the white wire of the light box to the white wire of the floodlights (neutral to neutral)

Twist the ends of the wires together clockwise and screw the wire nut onto the twisted wires

, and do the same for the black wires and the ground wires (always twist like-colored wires together clockwise and then twist the wire connector over them)

7. Then mount the light fixture on the light mounting bracket

8. Screw the light bulb into the light fixture and install the lamp shade

9. Turn on the power at the breaker panel and then turn on the light switch

How to replace a pull string light

This may be the easiest light to replace, as the pull string light does not have an exposed metal body

, so you’ll only need to connect the black and white wires to the light. Below are the installation instructions.

1. You will first need to disconnect the power from the breaker box

2. Test the circuit with a non-contact voltage tester to confirm that the power is off

3. Remove the old light by unscrewing the bulb and then unscrewing the wires

Then start installing the new lamp as follows:

4. Connect the white striped wire to the white screw, then wrap it around the screw clockwise and tighten the screw

5. Connect the black striped wire to the gold screw, then wrap it around the screw clockwise and tighten the screw

6. Screw the two screws that secure the light to the box

7. Turn on the power and pull the string light ready for use

Safety instructions on how to install the lighting device

1. First disconnect the power from the breaker box [Electricity comes from the street into your home through your electric meter

And from the electric meter it goes to the main breaker panel to the main breaker and then from there to the branch circuit breakers and finally to your home’s outlets, lights and appliances] so

Each lamp will be connected to a branch circuit breaker and you will need to turn off the light circuit breaker.

2. If the electrical panel is not labeled and you are not sure what circuit is for the light you are going to install

, turn off the main breaker which will shut off power to the entire house.

3. Turning off the power from the switch does not mean there is no power to the light and always turning off the power form breaker box

4. Double check the light with a non-contact voltage tester to make sure there is no power

5. The hot wire is for the light (black) carrying current, the white wire is neutral and the bare/green wire is ground

6. Most lamps have exposed metal parts,

It must be grounded by connecting the green screw on the mounting bracket to ground to make it safe and meet electrical code installation requirements.

7. Make sure the light fixture is grounded and that you have three conductors (black, white, bare) inside the box

8. Make sure you follow the polarity and connect the wires with the same polarity (hot to hot, neutral to neutral, ground to ground)

9. Anytime you install a heavy lighting fixture, make sure the electrical box is secure and supported to support the weight of the spotlights

10. Some national and local electrical codes require that a licensed electrician install a lighting fixture.

Check with your local electrical code authority if you are allowed to install a lamp and if you need an electrical permit to install a lamp.

11. Make sure you install light bulbs with the same or lower wattage they are rated for.

(If you install bulbs with a higher wattage than they are rated for, you may cause a fire.)

12. Always follow electrical code requirements and manufacturer instructions

alert:

When working with electricity, always first turn off the power to the breaker box and be sure to follow electrical code requirements

If you do not call a licensed electrician or if you are not sure of the wiring in your home, first check with your local electrical code authority if you are allowed to do this electrical task.

Hire a certified electrician.
