The LED Light Manager (LLM) from Smart Vision Lights is designed to drive as many as four separate lights including virtually all light types as well as drive four different quadrants or channels within an integrated photometric or multispectral ring light solution.
Each program is able to hold as many as four sequences with up to four lights. It is possible to set these lights at either ‘off’, constantly ‘on’, or any intensity level between the two. An OverDriveTM strobe mode is also provided.
By linking the LLM to a computer using an Ethernet cable, and using the browser-based interface to program the light via a series of drop-down menus, four individual LED light sources, or the four quadrants of a single LED illumination system such as a ring light can be programmed.
Technicians of any skill level can set program intensities and image sequences for each light by means of the intuitive user interface.
The preliminary target of the LLM system and light kit bundles will be 2D multi-light and 3D photometric stereo applications. The lighting system can solve formerly intractable tasks when it is used together with dedicated photometric stereo software from Matrox Imaging, SICK, TeleDyne DALSA, Cognex, or MVTec.
An example of such a task is the ability to locate a defect in a part’s surface. The photometric image processing software accomplishes this by taking successive images of an immobile object while it is lit up by a sequence of lights.
By doing that, it can establish the 3D surface orientation of every pixel on the surface of the object. By employing separate lights and/or cameras, this same method is able to produce 2D images of different regions of interest.
LLM can also be used for multispectral imaging solutions where LED wavelengths (not broad-spectrum white lights having optical filters before the sensor) are the spectral band selection mechanisms.
The cost of multispectral imaging solutions can be considerably cut by using the illuminating light’s color as the spectral band selection mechanism. This accordingly increases budgets for imaging applications.
