Desk lamps are a very important electronic accessory to have on the table, as they direct light towards the work surface and help reduce the load and ophthalmic functional problems. When you work or study, the work area must be properly lit, otherwise it can cause vision problems and make work stressful and uncomfortable. Proper lighting helps individuals see small details easily, this can be missed otherwise, which improves productivity. Touch desk lamps are lamps that are activated or controlled by a finger or hand.
Touch technology: temperature
The technology used in tablet computers is sensitive to human touch and is not powered by manual switches. The touch sensor can either be sensitive to the temperature or resistance of the human body. Temperature sensors are made of heat-sensitive diodes that reach a temperature change. Human bodies are warmer than the environment and thus the lamp can be controlled by human touch.
Touch technology: resistance
The human body is a good electrical conductor because we are made of 70 percent water. The touch of the human hand on the tablet lamp can close the lamp circuit and illuminate it and act as a switch. These types of techniques are usually rare to use because it needs a constant touch to be on and work. Lamps made by this technology will be on and working as long as the human touch is present and the circuit breaks when the hand and light go out.
Touch technology: Capacitance
This is the most common type of technology used in tablet computers that use the capacitive nature of the human body. Capacitance is the ability of an object or body to hold electrons in them. Each object or body has a capacitance number and when the human touches a capacitance-sensitive touch table lamp, it charges or fills the electrons in the lamp and turns it on. Most tablet lamps can also control the brightness and have different numbers of touches to adjust the brightness. Usually a single touch gives the least brightness and increases with the number of times the lamp is touched. It will be easier to control the lamp in this way.
