/ Dimmer
Device used to adjust the intensity of the light produced by a luminaire. There are different types of dimmers; they can be installed on the lamp's power supply cable, integrated into the transformer/power supply unit or be part of the building's own electrical system. When supplied, the Catellani & Smith pricelist indicates the type of dimmer and the dimming modes for its lamps. The end customer/designer is responsible for checking the compatibility of our products with the electrical system they will be plugged into. The use of incompatible dimmers could damage the luminaire. Any damage caused by the installation of incompatible dimmers will not be covered by the guarantee. Please note that specific dimmers for halogen lamps may not be compatible with LED light bulbs; it is therefore advisable always to choose specific dimmers for LED light bulbs (see section 5.5, p. 217- 218).
There are different types of dimmers for different purposes. Below is a list of the most common.
Typical of table or standing lamps; the device is integrated into the lamp's power cable. The light adjustment is performed with a cursor or pushbutton. This type of dimmer cannot be adjusted by remote control, domotic system or addition electrical system as this would irreparably compromise the luminaire.
The lamp regulation device is integrated into the transformer itself. It can recognize various signals and dimming protocols depending on its own inherent characteristics. Typically used with building automation systems, it requires an in-depth compatibility study to ensure correct communication with the systems own control units.
This is usually set into the recessed wall box of the buildings own system. It takes up the space of one or two modules, like a normal switch, and is used to adjust limited resistances and powers.
This type of dimmer is integrated into the building's electrical panel; it is designed to adjust different types of loads and very high powers. Lamp compatibility must be checked before this type of dimmer can be used.
This type of dimmer is integrated into the lamp so adjustments can be performed by touching the sensitive part of the luminaire or by using pushbuttons integrated into the structure of the lamp itself. This type of dimmer cannot be adjusted by remote control, domotic system or addition electrical system as this would irreparably compromise the luminaire.
The dimmer memory saves the status of the luminaire after a temporary interruption in the power supply - e.g. if the switch is tripped, a safety device (automatic cut-out switch) activated or in case of a power blackout (see sections 3.3.1 to 3.3.4). Some devices have a memory if the switch is tripped, but lose it in the event of a power blackout; this means that, once the power returns, the lamp may be turned on or off depending on the characteristics of the dimmer.
The lamp is off.
The lamp is on, adjusted according to a percentage set by the dimmer manufacturer.
