Light Intensity Controller (LIC)


Falcon supplies various light controls on the basis of LIC. Control in this case means that trigger signals can be processed and lights can either be operated in continuous mode, in trigger mode, or in strobe mode. 120 kHz pulse width modulations allows all controllers to ensure flicker-free and therefore reliable image processing.

The LIC series is split into four areas:
- Starting with LIC-VA, which meets basic requirements and can be easily integrated into applications.
- Then we have our latest product, LIC-CA2.
- The mid-range of the series - as measured by the technical specification - is represented by the models LIC-2256, LIC-4256,as well as LIC-8 and LIC-16.
- As a new addition to the line, LIC-S is specifically intended for„shape from shading“ applications.




LIC-CA2


LIC-CA2 provides 2 controllable output with selectable current and adjustable intensity. It is able to configure in continuous or strobe mode and CH1 and CH2 are able to take 2 input signals individually. The CA2 driver board uses metal core PCB which is directly attached to the casing main body, allowing better heat dissipation. LIC-CA2 is able to supply up to 2A per channel. With a cost-saving solution in mind, no resistors are needed for the application of LIC-CA2 as a current source controller.

The LIC-CA2 is equipped with the following features:



Features Descriptions
2 Channel Light Control LIC-CA2 provides 2 controllable output with selectable current and adjustable intensity.
Continuous Mode LIC-CA2 supports continuous mode in maximum of 2A per channel.
External Trigger / Strobe Mode LIC-CA2 is able to configure in trigger or strobe mode and CH1 and CH2 are able to take 2 input signals individually.
Built in Heat Sink LIC-CA2 driver board uses metal core PCB which is directly attached to the casing main body. This allows the controller to have a better heat dissipation and to deliver stable output when operating at max output current.
Easy Mounting and Miniature Size LIC-CA2 is designed with a space saving solution allowing an easier installation. The controller offers two easy mounting methods:

i. Direct Panel mounting.
ii. Optional method to clip for clipping the DIN rail mounting bracket at the DIN mounting rail.
Output Power LIC-CA2 is able to supply up to 2A per channel and maximum of 48W per channel.

LIC - VA


FALCON expanded the product line by developing a controller that is easy to operate and cost-effective, while also equipped with proven technology.
The result will be available as the LIC-VA starting in 2019.


The LIC-VA is available in two versions:
- LIC-VA1 processes a trigger signal.
- LIC-VA2 processes 2 trigger signals and switches these to the same number of outputs.

The trigger signals can have 5V or 24V levels. The LIC-VA has switchover times between 2μs and 5μs. In spite of its short switchover times, the LIC-VA is able to control up to 48V and 10 ampere per output in strobe mode. The associated output voltage depends on the available input voltage. In strobe mode, the maximum switch-on time is hardware-limited to 100μs to protect the light against overheating. The switch between individual operating modes is implemented with jumpers. A simple potentiometer is arranged as an intensity control for each channel. Like the entire LIC series, the LIC-VA also features 120 kHz pulse width modulation to prevent brightness fluctuations in the image recording.



Model Input / Output Voltage (V) Output Rating Per Channel (V) Quantity of Output Channel
LIC-VA1 12 - 48 24V 1
LIC-VA2 12 - 48 24V 2




LIC-X256N, LIC-8, LIC-16


In contrast to the LIC-VA the light intenity controllers LIC-X256N, LIC-8 and LIC-16 offer the possibility of communication. Via RS232-interface individual output-channels can be controlled. Intensities can be set and activated by software or manually. In addition, a display allows to adjust the brightness accurately. Like the LIC-VA, this series is also equipped with jumpers, which switch between the Continuous/Trigger- Mode (12/24 Volt) and the Strobe-Mode (48 Volt). In Strobe-Mode, the Switch-ON-Time is limited to 7.5ms by the hardware side. A special feature of the LIC-X256N is that different voltages can be connected. Thus it is possible to operate a controller with
12 volt and 24 volt lights.

LIC-S


The LIC-S is a controller with the ability to cost-effectively implement „shape from shading“ systems. Starting with the trigger signal from a camera or PLC, it continuously switches its outputs. Segment lights can then be used to obtain images with various illumination angles. The achieved results differ with the illumination angle. Software can then be used to process the results into a composite image with a meaningful result.


- The first result shows smallest scratches or bumps on the flat surface.
- The second result shows normal OCV/OCR applications which can be detected by synchronized switching of all segments.
This makes it possible to detect several characteristics in one application. Several LIC-S‘s can also be synchronized by software.

The hardware of LIC-S is similar to the hardware of LIC-X256N. The technology with 120 kHz pulse width modulation, the BCD display and the buttons on the frontpanel have proven themselves and are a decisive factor for Customers.
