Many people have installed in their homes chandeliers or ceiling lights with more lamps similar to those shown below.
Generally these chandeliers while being equipped with a number of lamps are wired so that all the lamps are driven all together, in practice it is expected the connection to only one switch that turns on or off all lamps simultaneously.
The lighting of the lamps provides a full and adequate lighting; necessary to perform certain tasks.
Often, however, there is no need for all that light, it would be convenient and useful to turn on only one or a few lamps located on the chandelier.
In many cases a less intense light may be sufficient or even pleasant to perform common household activities.
If for example in a chandelier with 5 lights it were possible turn on only 2, would have a sufficiently bright consuming less than half the electricity, resulting in a substantial saving MONEY.
With the present technique, to achieve the above example, it is necessary an intervention quite complex and expensive that only an electrician would be able to accomplish.
In fact, in addition to replacing the single switch with a double switch, it is essential to use another conductor inside the electric system and rewire the entire chandelier in order to obtain two groups of lamps controlled separately.
A simple and innovative solution to this problem is obtained using the energy-saving TWINLAMP lamps.
The TWINLAMP lamps can be realized both in FLUORESCENT technology that LED.
Constructively are identical to lamps currently present on the market, and therefore the cost of production and sales can remain unchanged.
The only difference consists in having placed on the base of the lamp a microswitch which operates on the electronic circuit internal to the same allows to obtain a double-differentiated control.
In a room where it is installed a chandelier with 5 lights controlled by a single switch you can get 2 sets of lights can be controlled separately simply by mounting the TWINLAMP lamps and replacing the single switch with a double switch.
It seems IMPOSSIBLE, here's how.
Together with each TWINLAMP lamp comes a small electronic component
(diode) should be used on the double switch in this way.
After preparing the double switch as shown in Figure simply connect the 2 wires that were attached to the old switch.
By operating on the switch SW1 is now likely that some lamp turns on, for example the 1 and 4, and remain off the lamps 2 / 3 / 5 .
If you want the switch SW1 is acting only on the lamps 2 and 4, you must operate the microswitch on the lamp 1 in order to turn it off, and the microswitch on the lamp 2 in order to turn it on.
You do not need any other operation; the lamps 2 / 4 switch on pressing the switch SW1 while the lamps 1 / 3 / 5 with SW2.
This system works on any chandelier with multiple lights; at any time, simply by operating the microswithc at the base of the lamps can be changed at will the combination switches and lamps.
Currently the TWINLAMP 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 TWINLAMP lamps.
