IE LG3 Light Box
The compact chart light box LG3 shines because of its high dynamics. LEDs provide the light source with a correlated color temperature of 5000 K.
LG3 creates new possibilities in laboratories and expands the test areas for dynamic-range measurements considerably through modern lighting technology. In this way, measurements of high dynamic range can also be realized with short, practical exposure times. Testers can choose between pulse width modulation in a constant mode with 32 kHz and variable duty cycle or flicker mode variable frequency from 10 to 500 Hz and variable duty cycle. Light sources working with variable frequencies can be simulated e.g. traffic lights, vehicle or street lighting. In that way cameras in the security and automotive area can be tested and optimized for all kinds of real life situations.
Its important features are:
- high intensity >150,000 lx
- min. intensity <10 lx
- variable frequencies
- variable duty cycles
- high homogeneity >95%
- dimmable in fine steps
- stabilized intensity in normal and low intensity mode
- correlated color temperature (CCT) of 5000 K
Via the external control and supply unit, two illumination methods can be selected in three intensity ranges.
- Pulse width modulation PWM
- Flicker modus 10-500 Hz
Each with:
- normal Modus: 0-100% 32 kHz / <100 to >65000 lx lx
- low Modus: 0-100% 32 kHz / <10 to >6500 lx
- high Modus: 100% max. 60s lighting duration / >150,000 lx
The standard test chart size for the illumination device is D280 format.
