What are The Different Parts of LED machine vision lighting?

LED machine vision lighting is a critical component in the field of automated inspection and quality control, typically equipped with one or more high-intensity light sources. The design and selection of lighting are tailored to the specific needs of the application and the desired illumination performance. Common types of LED machine vision lighting include Machine Vision Light, Fiber Optic Light, Custom Light, Light Controller, Filter, Lens and Camera. 

Here are the main parts of an LED machine vision lighting:

Lighting Sources: The primary component of any machine vision lighting system is the light source itself. In the context of LED lighting, these can include various types of LEDs such as high-power light-emitting diodes (LEDs) that can be programmed for current and timing to achieve increased brightness and overdriving capabilities.

Camera and Photometric Tunnel: The camera is used to capture images of the object under inspection, while the photometric tunnel is a structure that allows for the acquisition of the lighting pattern projection at a specific distance, such as 25 meters, and includes necessary tools for the vision sensor placement。

Host PC: This computer is responsible for synchronizing all processes, executing computer vision algorithms, and controlling the positioning of the lighting and other components.

Tooling: Tooling is used to secure modules and allows for relative movement between submodules. These devices interface with positioning software components and are controlled by PLCs connected to the host PC via Ether CAT.

LED Board: The LED board is a dedicated board assigned to five high-power LEDs: D9, D11, D14, D15, and D16. These LEDs are specified in the datasheet to have a forward current of up to 1.5A and provide a uniform chart even at low currents of 300mA (up to 50mA with increased tolerance). The datasheet also provides data for the allowed pulse handling capabilities, with peak pulse currents up to 2.5A.

Screwdriver: An electric screwdriver is used to secure the submodules. Once the optimal position is achieved, the folder screws will use a three-axis electric screwdriver to fix them in place.

PLC (Programmable Logic Controller): The PLC is used to control the movement of elements and the illumination of the LED module. The PLC controls the illumination of the LED module through power drivers.

LED Lighting Control: This component allows for the control of a string of multiple high-power LEDs, enabling the safe overdriving of LEDs for increased brightness.

These components work together to form the LED machine vision lighting system, which provides the optimal lighting required for machine vision applications, ensuring high contrast and accurate feature detection in the captured images.
