For the lighting of the home environment generally are installed ceiling lights or chandeliers inside which is mounted one or more lamps with a given power to light up the room adequately.
Often during daily use one perceives the need to be able to decrease the light intensity emitted by the lamps in order to obtain a more comfortable lighting; obtaining a considerable economic benefit associated with corresponding savings of the electricity.
For several years, devices and systems have been developed to achieve this objective, namely to reduce the electricity to be sent to the lamp in order to obtain lower brightness and consumption.
The most common devices that use this technique are the DIMMER (see picture on the right).
These devices generally installed in place of the switch allow you can adjust the light intensity of the incandescent lamps from a minimum value to the maximum.
The use of these devices, however, also entails a number of disadvantages;
- High cost of dimmer (more than 20 euro).
- Poor compatibility with modern CFL / LED lamps (in fact, only a few manufacturers offer dimmable lamps compared to the wide range of models available).
- High cost of the dimmable lamp.
- Inability to adjust the light intensity of the lamp from multiple points of control.
To avoid these drawbacks, and in the meantime get a significant cost savings would be more logical and appropriate to integrate the system of adjustment of light directly into the body of the lamp (together with the electronic control circuit already present in it).
Following this criterion has been developed DIMLAMP lamp.
The DIMLAMP lamp achievable in both CFL / LED technology is similar to the existing ones, and therefore can also be used to replace any conventional lamp.
Using the wiring diagram in the figure below, you can control the dimlamp lamp to turn on / off and adjusting light intensity from one or more points through simple buttons.
Through a diode (D1) connected in parallel with a push button, the dimlamp lamp is constantly powered with only one half-wave (either positive or negative).
Pressing any button for an instant you send to the lamp the alternating current in full wave, in this way you can control the lamp to achieve the desired function:
- a short pulse acts as a reversing control of the on / off state of the lamp.
- an extended pulse activates the control circuit to perform a continuous variation of the brightness of the lamp from a maximum value to a minimum and vice versa.
Being the lamp always powered (even when it is being turned off) it is possible to implement inside other electronic control circuits, (motion detectors, twilight, remote controls, etc.) thus providing additional functionality.
Thanks to this type of lamp and without intervention on the electrical system shall be available a wide variety of functions combined with versatility of use; e.g. to be able to control the lamp equally and simultaneously from both your SMARTPHONE that the normal button on the wall (feature precluded also for the numerous smart lamps currently on the market).
Currently the DIMLAMP lamps ARE NOT FOR SALE
, but have been installed in various home environments to test efficiency and durability; will be marketed as soon possible and will be available to the public.
WARNING! use this type of connection ONLY to control the DIMLAMP lamps.
