Features and Usage of Strobe Controllers

Just like machine vision light sources, there are multiple types of vision light source controllers. Among them is the strobe controller. Let's explore the "features and usage of strobe controllers" with falenses technology.

What Is the Purpose of a Strobe Controller?

The SC series strobe controller is a high-performance LED light source controller developed by our company. Unlike conventional light source controllers, strobe controllers control the on/off of their output voltage according to a preset pulse width to manage strobe lighting for LED light sources.

When the output voltage is turned on, the voltage is generally twice that of conventional controllers (for example, a 24VDC LED light source can have an output voltage of up to 48VDC), with a maximum on-time of 1000 microseconds. This allows the strobe controller to significantly increase the instantaneous brightness of LED light sources. Because the light source is on for only a short time, internal heating of the LED is minimized, thereby greatly extending the light source's lifespan.

Features of a Strobe Controller

1. Adjustable Pulse Width: The width of the output voltage pulse (i.e., the light source's on-time) can be set from 1 to 1000 microseconds, with adjustable pulse width ratios.

2. Significant Brightness Increase: The strobe controller can increase the instantaneous brightness of the light source by over 300%, while extending the lifespan of the light source.

3. Camera Trigger Synchronization: Automatically outputs a camera trigger signal and ensures that the camera is triggered synchronously after the light source is illuminated.

4. External and Internal Trigger Modes: The strobe controller can work in external trigger mode, where the light source is illuminated as needed, or in internal trigger mode, where it is illuminated at a fixed frequency.

5. Automatic Protection: If the load current exceeds the controller's maximum value or there is a short circuit, the controller automatically stops outputting to prevent damage.

How to Use a Strobe Controller?

Method 1: Internal Trigger Mode

• In this mode, the controller outputs at a fixed period ranging from 15 to 1000 milliseconds (adjustable). External triggers are ineffective, and the camera signal terminal outputs a synchronization signal.

Method 2: External Trigger Mode

• In this mode, the light source is turned on when an external trigger signal is received. The camera signal terminal outputs a synchronization signal.

By understanding these features and usage methods, you can effectively integrate strobe controllers into your machine vision system, optimizing performance and lifespan.
