How do Touch Lamp Circuits Work?
As the name implies, touch table lamps are lamps with touch-sensitive switches like the bedside table touch lamp, and this works in contrast to a flip or pushes the electronic control.
How to Build?
Here, we’ll look at three things: Touch lamp circuit using NE555 timer, touch lamp circuit using Arduino, and touch lamp control dimmer.
Rounding Up
Most touch lamp circuits feature three brightness levels without the use of three-way bulbs. Making contact with these lamps doesn’t just turn them on/off, and it switches the brightness level from dark to dimmest to second brightness to brightest.
How many volts does a megohm potentiometer use?
A modification in this design is indicated in the above diagram, by using a 1 megohm potentiometer working like a ballast resistor and a couple of 45 volt or four 22.5 volt dry batteries as the voltage input source.
How does a potentiometer work?
Allowing the potentiometer to be in this position, the neon must then begin blinking at different flashing rates as determined by the value of the selected capacitor.
How does a neon bulb work?
The neon bulb gets a voltage supply equivalent to the charge developed across the capacitor terminals. As soon as this voltage reaches the breakdown voltage of the lamp, it switches on and forces the capacitor to discharge via the gas inside the neon bulb, resulting in the neon to glow.
What is the purpose of replacing R with a variable resistor?
Replacing R with a variable resistor could enable adjustment for any specific desired flashing rate. This could also be further enhanced like a novelty light system by attaching an array of capacitor neon circuits, each having its own neon lamp in cascade as shown below.
What happens when a neon lamp capacitor discharges?
When the capacitor discharges fully, it inhibits any further current to pass through the lamp and thu s it shuts down again until the capacitor has gathered another level charge equal to the firing voltage of the neon, and the cycle now keeps repeating.
How many volts does a neon bulb have?
Without any precise info given, it may be supposed that a neon lamp may have simply no resistance while it is illuminated, but may have a drop of around 80 volts across its terminals.
How many volts does a neon light need?
Commonly the firing, or breakdown, voltage of a neon lamp could be anywhere between approximately 60 to 100 volts (or occasionally even greater). The continuous current rating is fairly minimal, generally between 0.1 and 10 milliamps.
How to remove a lamp from a harp?
Unplug the lamp and disassemble it. Start by disconnecting your lamp from its power source. Now, remove the lampshade from the harp, which is the metal piece that surrounds the bulb and connects to the lampshade. Afterward, remove the harp and unscrew the light bulb from the socket base and remove it.
How to separate lamp cords?
Separate the top 2 inches (5.1 cm) of the lamp cord. Your cord is made of 2 wires connected together: one that is ribbed (neutral) and another that is smooth (hot). Pull them apart with your hands or—if they're tightly connected—use a pair of scissors to cut along the middle indent that separates them.
What is a lamp cord made of?
Each lamp cord is made of 2 wires stuck together: one with smooth insulation and one with ribbed insulation. Take note of each one for later on. If you purchase a flat cord, use a clamp-style wire plug. For round wires, use a two-pronged wire plug.
How to feed a new cord to a lamp?
Pull the old cord through the base of the lamp to feed the new cord through. Pull on the old cord from the bottom of the lamp until the new cord appears . Now, pull on the old cord from the edge of the lamp base to bring the new cord through the channel.
How to make a cord escape for a lamp?
Create a cord escape within 2 inches (5.1 cm) from the bottom of the lamp base. The cord escape will run the lamp cord from the base and connect to a plug. Attach a 3⁄8 inch (0.95 cm) bit to an electric drill. Make sure the length is at least the radius of your lamp base. Hold the base steady with one hand and drill the hole horizontally ...
How to reattach a socket to a lamp?
Reattach the socket to the socket cap. Slide the insulator tube that acts as the outer covering of the socket over the inner part of the socket. Be sure that it slides over the lamp switch. Now, press the socket down into the socket cap—this may take a bit of effort.
How to make a lamp base?
Drill a vertical hole through your lamp base. Attach a 3⁄8 inch (0.95 cm) bit to an electric drill. In terms of length, make sure the bit is at least half the length of the base material . Now, drill a vertical hole through both sides of the base to meet in the middle.
Circuit Operation
The above circuit operates in the following manner: The capacitor 220n 400V behaves as a voltage dropping resistor and ensures that the current flowing is not more than 12 mA. The diodes 1N4007 bridge rectifier turns the AC voltage into a DC voltage i.e. LEDs can only operate from a DC voltage.
Applications and Uses
They are proving their worth in many specific residential and business lighting tasks such as in desk lamps.
What do you need to make a lamp?
To make a lamp all you need is the vessel and a lamp kit. The vessel can be any vase, tin, wood box or even a pitcher. Basically you can make a lamp out of anything that you can get a cord into. The basic lamp kits you can buy for $12 includes the wiring, the harp and all of the hardware.
Steps to Make a Lamp
The first step to making a lamp is to make sure you can get the cord up through the bottom or the side of your vessel. I drilled a hole in the side of the tin toward the bottom. The second step is to decide how the top will fasten in. If you are using something with a top, it’s easy to drill a hole in the and feed the lamp wiring through that.
How to tell if a light bulb is in series?
Consider a very simple circuit consisting of four light bulbs and one 6 V battery. If a wire joins the battery to one bulb, to a second bulb, to a third bulb, then back to the battery, in one continuous loop, the bulbs are said to be in series. If the three light bulbs are connected in series, the same current flows through all of them, and the voltage drop is 1.5 V across each bulb and that may not be sufficient to make them glow.
What happens when a circuit is closed?
When the connections are made properly, the circuit will “close” and current will flow through the circuit and light the lamp. Once one of the wires is removed from the power source or a “break” is made in the flow, the circuit is now “open” and the lamp will no longer light.
What is the difference between a parallel circuit and a parallel circuit?
Parallel Circuits. In a parallel circuit, the voltage across each of the components is the same , and the total current is the sum of the currents through each component . If two or more components are connected in parallel they have the same potential difference ( voltage) across their ends.
How many V does a light bulb drop in a series circuit?
If the light bulbs are connected in parallel, the current flowing through the light bulbs combine to form the current flowing in the battery, while the voltage drop is 6.0 V across each bulb and they all glow. In a series circuit, every device must function for the circuit to be complete.
What happens when a light bulb burns out in a series circuit?
In a series circuit, every device must function for the circuit to be complete. One bulb burning out in a series circuit breaks the circuit. In parallel circuits, each light has its own circuit, so all but one light could be burned out, and the last one will still function.
What is an electrical circuit?
Basic Circuits. An electric circuit is an unbroken path along which an electric current exists and/or is able to flow. A simple electrical circuit consists of a power source, two conducting wires (one end of each being attached to each terminal of the cell), and a small lamp to which the free ends of the wires leading from the cell are attached.
What are the two types of circuits?
In practical application, circuits are “opened” by such devices as switches, fuses, and circuit breakers. Two general circuit classifications are series and parallel. The elements of a series circuit are connected end to end; the same current flows through its parts one after another.
Step 2: Explore the TTP223 Module
The TTP223 comes in various form factors, but the one shown here is the most common. They are also extremely cheap, as little as $0.10/each.
Step 3: Test the Circuit
Before we get started, I strongly suggest you wire up the circuit on a breadboard so you can become familiar with the wiring and each component. Once we get started, the lamp may have a restricted space to work in, and knowing the circuit now will help later.
Step 4: Circuit Diagram
Study the attached diagram and make a plan before you start. Measure the existing lamp's wires and use the appropriate gauge wire when working with the mains AC part of the circuit. In my case, I used 18AWG wire where I needed new connections.
Step 5: Mounting Electronics
My donor lamp has a large concrete block in the base for ballast, which is common. In my case, the AC module will fit between the concrete block and the side of the lamp, but the relay is just slightly too large.
Step 6: 3D Print a Switch Box
Above is an STL file for the 3D box that I designed and printed for my lamp. This box could be used with most lamps but may not fit exactly the same way mine did, which is fine.
Step 7: Testing Lamp
Before we do the final assembly, let's do a quick test. I used a small 3-pin header and a standard 3-pin female connector to attach the TTP223 to the rest of the circuit. This makes it very easy to mount after everything is assembled, and it allows you to remove the box if needed.
Step 8: Final Product
And there you have it. You just converted a regular lamp into an awesome touch lamp! No more struggling to reach those crazy tiny switches in the dark.
How to make a lamp?
To build a lamp, start by getting a lamp kit at your local hardware store, which will come with a detachable harp, a cord set, a socket and shell, a finial, and some basic hardware. You'll also need a base for your lamp, like a book or a wine bottle, since you won't get one in a lamp kit.
What is the neutral wire on a lamp?
Usually, the neutral wire will be surrounded by ribbed insulation. If you're unsure, refer to the instructions that came with your lamp kit. If the wires have two colors at all, the white is the neutral wire and the black is the hot wire.
How to tie wires to a doubled wire?
Doing this will prevent the wires from falling through the rod to the base. To tie an underwriter's knot : Bring the left wire down so that it's facing to the right, in front of the doubled wiring.
Where do you run a lamp cord through a socket?
If you don't wish to run a rod through your lamp base, sockets are available that allow the lamp cord to come through the bottom part of the socket shell.
How do I remove insulation from a cord?
Strip the wires. Pull the two covered wires at the top of the cord apart, separating about 4 inches (10 cm) down the cord. Using wire strippers or a knife, remove the insulation from the top 1 inch (2.5 cm) of the cords.
What should the base of a lamp be?
The base for your lamp should be sturdy enough to stand on its own , even after you add lamp apparatus and a shade on top. If you have a hollow base that you need to stabilize, consider partially filling it with something like marbles or sand. Some ideas for lamp bases that you could use: Wine bottles. Log or timber.
