Description
Description
Function and application
The OT EASY 60
II LED control unit can be used to implement static and dynamic light-
ing concepts.
Function
The OT EASY 60
II LED control unit enables the manual and automatic control of up to
four LED luminaire groups on separate channels. Up to 4 x 16 lighting scenes can be
programmed, called up individually or run through cyclically in up to 4 sequences (e.g.
to simulate daylight).
A colored light mixing system can be set up by assigning LED colors to the outputs.
The functions can be executed via a remote control, pushbutton, switch, timer switch,
motion detector or PC, depending on the installation.
Important definitions
Scene, lighting scene
A lighting scene defines the lighting situation in a room or the color resulting from the
mixing of individual LED colors (red, green, blue).
Example 1: Coloured effect lighting
The LEDs have different colors (red, green, blue, white). They are set to different
brightness levels according to the desired shade of color (mixed color of the room
lighting). This mixing color is a lighting scene.
Example 2: Daylight simulation
White LED modules with different colour temperatures of 3300 K and 6500 K in con-
junction with red and blue LED modules are suitable for daylight simulation in areas
at a great distance from a window front, ceiling lights and task lighting with variable
colour temperatures. Very slow cross fades are imperceptible to the human eye.
Sequence
A sequence is the automatic retrieval of stored lighting scenes and their cyclic play-
back.
Fade time
The fade time is the time in which the lighting system changes from one lighting scene
to the next in sequencer mode.
Cycle time
The cycle time is the time in which the daylight simulation system runs through a
complete daylight cycle.
