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, aspherics2optical 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 Ein 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 Fis provided on the back of the head allowing adjustments to be made along with the yellow focusing
ring Eto 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 Dare in a fixed position while
the fourth Cserves 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.

6 Handling Power Supplies
For AC ballasts:
When power supply is switched Poff, connect the ballast and the light head with 5-pin XLR connector J. Then
connect the input cable Oof the ballast to the AC mains.
Switch Pon the ballast. The signal LED J„ON“ should light up in green. (If the LED is flashing or no light ap-
pears, that indicates damage.)
For Battery ballasts:
When power supply is switched Poff, connect the ballast and the light head with the cable Kwith the 5-pin
XLR connector H. Then connect the input cable Qto the ballast Sand to the battery or a car cigarette lighter
output. The signal LED J„ON“ should light up in green. This indicates the battery is connected and charged.
Switch Pon the ballast. The signal LED „ON“ should turn off.
NOTE that in Battery ballasts, this LED‘ s function is inverted. The LED does not light while the light head is
operating. When the battery is exhausted, the ballast switches off automatically and the green LED starts blinking
in short intervals.
DT4 has a rotary knob to adjust intensity (dimming) I.
DT4-BI, bi-color power supply, has 2 rotary knobs. One for dimming I, another one for adjusting the color tem-
perature Mfrom 2700K to 6500K.
For devices with display:
When operating dimming knob Iin manual mode, display shows ‚d‘ from d00 to d99 (d00 to dff in some ver-
sions).
When operating knob for color temperature Mregulation, display shows equivalent color temperature, starting
with 27 (for 2700K) all the way to 65 (for 6500K).
For devices with DMX function:
To set DMX address push the buttons Vat the left ( ) and right ( ) sides of the display Usimultaneously,
release, then select address ‚up‘ with the right and ‚down‘ with the left button. Auto store after 10 sec. A dot in
display indicates a correct DMX signal. For manual control set the address below channel 1. Use the rotary knobs
to adjust color or dimming levels.
Thermal protection/missing lamp head:
On the ballast there is a signal LED J„heat“. In case of overheating of the light head, the ballast automatically
switches off and the LED „heat“ lights up in red. After cooling down, the ballast recovers and continues its normal
operation. The „heat“ LED lights up in red also in case of damage in the output cable or missing lamp head. After
recovering the connection, the ballast continues its normal operation.
Mismatch conditions:
Should a mistake arise, where the DLED4 mono-color light head D or T is connected with DT4-BI, bi-color power
supply, both buttons influence brightness.
If you connect the DLED bi-color light head with the mono-color DT4 power supply, only one of the two color tem-
peratures will be active and cannot be changed, but can be dimmed.
No damage will occur to light head or power supply.
