Lighting is an essential part of creating the ambiance of any room, be it in your home or workplace. Choosing lamps to light up your space is a careful process that needs much consideration.
While there are traditional lamps that can be turned on or off by toggling a switch, a more convenient way of controlling light in your room is by a touch-sensitive lamp.
As with many modern gadgets and fixtures, touch lamps work on certain conditions and principles. If you want to know how do touch lamps work, read on and discover!
How Do Touch Sensitive Lamps Work
There a few different ways in which a touch-sensitive lamp works. But before that, you might want to know how the wires and the circuit are connected.
Inside the lamp body, there lies a touch-control box. Through this box, the lamp plug cables and the cables to the socket are connected. There is one extra wire which is connected to the metal part of the lamp.
This additional wire makes the lamp turn on or off when the human hand touches any part of the metal on the lamp.
Read on to know the details of the mechanisms by which a touch-sensitive lamp works.
Capacitance means the capacity of any object to hold electrical charges or electrons. While the touch lamp has its individual capacitance, it differs from that of humans.
With the circuits that are part of the components of a touch lamp, it can detect when there is a change in capacitance. Therefore, when a human touches the lamp, the electrical switch in the lamp turns on.
When the hand is removed, the capacitance changes and hence, the lamp either turns off or gets into a different setting.
Did you know that our body is warmer than the air that surrounds us? When touch-sensitive lamps are programmed to detect a change in temperature, they start to work. So, when we touch this type of lamp, it reacts to the heat emitted from our hands and turns on.
About 60% of the human body contains water, making it a good conductor of electricity. When you touch the lamp, you come in close contact with the circuit, thereby closing it. That’s why the touch lamp lights up.
The human body is a good antenna and that is proven when you touch a TV or a radio and the reception improves immediately. Similarly, when you touch a lamp, it detects the change in radio reception and reacts to your touch.
Touch Sensitive Lamps Turns On By Itself – What To Do
When you see the touch lamp turns on by itself, you can try a few things to get it working properly again.
The control-box inside the body of the lamp can get affected due to power fluctuations. In these circumstances, the touch lamp may remain on. If this is the case, then the control-box needs to be replaced.
In most cases, the touch lamp remains on because of RFI or radio frequency interference. Objects like your computer, cell phones, and others may cause your touch lamp to be on. You could take out the control-box and put a mechanical switch in its place.
If you want to teach your kids about how things work, touch lamps can be a great start. Almost all homes have these lamps in the living room, the nursery, and the bedroom.
Touch-sensitive lamps are convenient to use as there’s no switch to turn it off or on. If you just reach out and touch any metal part of the lamp, it will activate or deactivate as per your preference.
With easy-to-understand mechanisms, you can pass on the knowledge of how do touch lamps work to your kids. That way, you can have quality time with them as well as ignite their curiosity about how things function around us.
