    Product Overview

    With modern lighting technology, the LG3 creates new possibilities in image laboratories by significantly expanding the test area for dynamic range measurements. The LG3 is capable of illuminating a high contrast test target with over 150000 lx (for the LG3 to make an exact indication of the intensity on the chart in luminance [cd/m²], a measuring device is required, e.g., PRC Krochmann RadioLux).

    As a result, high-dynamic-range measurements are possible with short, practical exposure times. The user can also adjust the intensity, while the LG3 temperature management ensures that the light's CCT (correlated color temperature) remains constant.

    Another unique aspect of the LG3 is the flicker mode. With this feature, the user can choose between a constant-pulse-width modulation mode at 32 kHz and a variable-duty-cycle flicker mode, with a range of 10 to 500 Hz. With the LG3, light sources working with variable frequencies can be simulated, e.g., traffic lights, vehicles, and street lighting. Now, cameras in security and automotive applications can be tested and optimized across a wide range of real-world scenarios.

    The standard test chart size for the illumination device is D280 format.

    We also offer an LG C++ API (sold separately) for building a custom measurement environment.

    Via the external control and supply unit, select two illumination methods in three intensity ranges.

    • Pulse width modulation (PWM)

    • Flicker mode 10-500 Hz

    Intensity Ranges

    Normal mode

    0-100% 32 kHz / 100 to 65000 lx

    Low mode

    0-100% 32 kHz / 10 to 6500 lx

    High mode

    100% max. 60s lighting duration / 150000 lx

    Key Features

    High intensity

    The LG3 is capable of illuminating a high-contrast test target at over 150000 lx.

    Variable frequencies

    Simulate light sources that have variable frequencies, e.g., traffic lights.

    Variable duty cycles

    Choose between a constant PWM mode of 32 kHz and variable duty cycle, or the flicker mode with a range of 10 to 500 Hz and variable duty cycle.

    High uniformity

    The LG3 offers a uniformity of > 95 % for the active chart area (measured on a chart plane).

    Dimmable in fine steps

    The light source has the possibility to be dimmed in fine steps for low-light testing.

    Software and APIs

    The LG3 comes with LG control software, and we also offer an LG API (sold separately).

    Use Case - Simulate Variable Frequencies

    Many camera systems, particularly those in the automotive and security industries, regularly interact with light sources that vary their illumination frequency or flicker. These variable frequencies are often challenging to simulate in a test lab environment but are essential for testing the camera's overall performance and safety (e.g., how an ADAS application reacts and adjusts to flickering traffic signs). The LG3 provides a compact solution for generating variable-frequency and pulse-width modulation (PWM) signals (i.e., flickering light) in a test lab, giving you full control over your test environment.
