Practical people care not only about the beauty of the interior, but also about rational spending of funds. Scientific and technical progress allows us to combine comfort and economy. We will talk about a dimmer that can be installed instead of a conventional switch. Thus, the user will be able to change the brightness of the lighting in his apartment (that is, save up to 50% of electricity).
Adjust the brightness of the light
A dimmer is a device that allows you to influence the intensity of artificial light. With the help of such a device, the voltage supplied to the lamp is increased or decreased. The control signal is transmitted to the power element, thanks to the internal potentiometer. When using the simplest dimmer model, the brightness of the light will depend on the angle of rotation of the potentiometer handle.
A more advanced version
The push-button device is more flexible in control. It is permissible to connect several buttons in parallel at once to make adjustments from 3-4 places. The maximum length of the wires in this case can reach no more than 10 meters. Note that the push-button version is manufactured using a microcontroller. When installing the device, it is recommended to strictly follow the manufacturer's instructions (the model's power must correspond to the expected load). Special LED lamps will be required to control the intensity of lighting.
Additional information
Dimmers without fuses are much easier to connect, since you don’t need to figure out where the phase is and where the “zero” is. This is very important in situations where the wiring is done incorrectly (i.e. the polarity of the connection is easy to confuse).
Note that devices with a large switch work like this: a long press with the key on changes the lighting intensity to the value preset on the controller.
The choice is yours
So, mechanical devices operate using a potentiometer. There are remote models controlled by transmitting signals from a remote control. Electronic devices with touch control are also produced.
Before buying a device, pay attention to the length of the LED strip . It is necessary that the power of the selected device corresponds to the power of the strip power supply .
The above-described method can be used to illuminate entrances, stairwells, and also to install interior lighting. The system is useful for lighting urban infrastructure (tunnels, roads, building facades, etc.). All this is effectively used in Smart Home systems, allowing you to optimize the operation of LED strips, modules, and rulers. The size and shape of the body of such devices resembles conventional sockets and switches. This feature allows you to install devices in building structures instead of standard key switches.
A dimmer with an RGB controller is used for professional lighting of facilities where entertainment events, celebrations and concerts are held; in various advertising structures and in design solutions for residential premises.
