5 Handling Light Head
Mounting the Light Head
The light head may be attached to any stand or mounting fixture which utilizes a standard 5/8“ (16mm) stud
A
.
The stand fitting accepts these studs in both vertical and horizontal positions.
The DLED4 series light heads may be rotated 360° around the axis of the stand fitting. Several spring washers
and friction discs provide an even friction to the stand fitting.
Should this friction become too low, the self locking nut may be tightened with a 10 mm wrench.
Connecting Power Supply
The DLED4 (D, T and BI) is equipped with a 5-pin male XLR connector located on the back of the light head. Both
AC and DC power supplies may be connected to this connector. With the SE-Series (Studio Edition) the power sup-
ply is built-in. For more detailed information please see chapter „6 Handling Power Supplies“ on page 19.
Dimming
The DLED4 fixture may be dimmed by the dimmer knob located on the power supply.
More detailed description in chapter „6 Handling Power Supplies“ on page 19.
Focusing
The dedolight DLED4 LED light fixture offers a great variation of beam angle and intensity - 60° to 4° (1:20).
The dual lens, aspherics

optical system offers even light distribution throughout the entire focusing range.
The beam angle is continuously adjustable by turning the yellow ring on the light head.
You will notice that when moving to the wide angle/flood position, the entire light head becomes shorter, while
turning the yellow ring
E
in the opposite direction (spot), makes it longer. A narrower beam is created towards
the spot position. In doing so, the light head grows in length exposing the extra cooling devices which are other-
wise hidden inside the light head.
Heat
Although it is commonly believed that LED light sources produce no heat, this is not true. On the contrary, LED
light sources still turn about 85% of the energy consumed into heat. Therefore, cooling devices are necessary.
With prolonged use, the cooling ribs, visible at the rear of the light head, will become warm. A temperature sensor
will turn the light off in the unlikely case of overheating. This sensor will automatically reset once the temperature
returns to normal.
A handle
F
is provided on the back of the head allowing adjustments to be made along with the yellow focusing
ring
E
to adjust the angle of the beam.
Accessories for the Light Head
A variety of accessories may be attached to the accessory holder. Three of those
D
are in a fixed position while
the fourth
C
serves to lock the accessories in place.
For example:
• Barn doors (e.g. eight leaf)
• Scrims
• Light shield ring
• Color conversion filters
• ND grad filter
• DP1.2 imager/projection attachment for gobo projections or iris
• DP2.2 imager/projection attachment with built in framing shutter blades dedolight DP1, DP2 and
DP3 imager/projection attachments may also be used but will not provide perfectly smooth and
even light distribution.
