Lighting supports selling
Lighting control systems always play an important role when
it comes to presenting products or rooms in a favorable light.
A fitting mood can be achieved in rooms and spaces by adjusting
the brightness of individual lamps. To achieve that mood, universal
dimmers are used that enable appealing adjustment of the lighting
brightness.
Conventional lamps are giving way to LED lamps
The term “retrofit” – to install something retroactively – suggests
that LED retrofit lamps are supplanting conventional incandescent
and halogen lamps. Products of the same standard socket sizes
(E27 and E14, etc.), similar designs (as bulbs, spotlights and candles)
and directional characteristic (global, spot, etc.) are available,
some dimmable and some not.
In addition to LED retrofit lamps with integrated electronics, there
are LED lamps controlled by an LED driver that serves as an electrical
ballast device. These LED drivers act as electronic transformers.
Dimming of LED lamps
In general, all conventional incandescent and halogen lamps are dim-
mable. In contrast, LED lamps are equipped with electronic switching
for control purposes. As no uniform standard is available for these
electronics, every LED lamp behaves differently. The lamp manufac-
turer defines the brightness range within which an LED lamp can be
dimmed. Lamp manufacturers mark LED lamps correspondingly in
their technical datasheets, on the packaging or on the product itself.
Hence, dimming LEDs is only implementable within the scope of
possibility set by the LED manufacturer. Because the electronics
installed in dimmable LED lamps are not standardized, the range
of dimmabilty can only be guaranteed by testing.
