HEAD 

 

 

 

The LED lightHEAD enables you to create individual light types with the built-in iQ-LED technology. 

Besides the 10 iQ-LED devices there is an additional fluorescent lamp of type F11 mounted into the 

LED lightHEAD by default. This lamp can be switched on and off with button 

F11

 [5] and its intensity 

varied with a slider [6] and a value input field [7]. During a sequence play back this lamp is turned off 

in order to attain the selected spectrum and illuminance.  

For sequences all illuminants created in the illumination settings panel (

chapter 4.3.3

) are available in 

the  third  column  of  the  sequence  list.  Add  a  start  and  end  time  to  complete  one  illumination  period. 

Since switching time bewtween illuminants is very fast periods down to 50 ms are possible. 

Underneath  the  table,  information  about  existing  spectral  calibration  and  illuminance  adjustment  is 

displayed [2] (see 

chapter 4.3.3

). It is possible to switch the selected illuminants on an off by enabling 

this functionality with lamp button [4]. The click on one of the selected illuminants in the list to turn it 

on.  

The  temperatures  of  the  iQ-LED  modules  have  impact  on  the  temporal  stability  of  the  selected 

spectra.  The  optimal  operating  temperature  is  between  33  and  36  °C,  thus  the  lightHEAD  needs 

generally be warmed up before usage. In the panel the temperature of the coldest module is displayed 

[3]. Click the button to the left of the temperature display to show a more advanced 

view.  The  thermometer  is  colored  blue,  if  the  (coldest)  module  is  below  the 

working  temperature,  green  in  the  working  range  and  red,  if  the  temperature 

exceeds  the  working  range.To  accelerate  warm-up  click  the  lamp  button  to  the 

right  of  the  thermometer  –  all  iQ-LED  modules  are  switched  on  with  all  22 

channels  set  to  100  %  illumination.  When  the  lower  temperature  threshold    is 

reached the modules are switched off. Click the thermometer button to the right in 

order to view the temperatures of all 10 iQ-LED modules.
