The Siemens built-in ring light 6GF3540-8DA13 is a lighting system specifically developed for MV540 devices in red multi-design. It serves as an integrated light source for industrial image processing systems of the SIMATIC MV500 series and enables precise, even illumination of objects in the immediate vicinity of the camera. The device is designed for use in automated production environments, where constant and reproducible lighting is required for optical detection of patterns, colors, or structures.

Applications
The ring light is primarily used in applications of industrial image processing, particularly for surface inspection, detection of color or structure differences, and part positioning. The red light color is especially suitable for distinguishing materials that reflect differently in the red spectral range and provides high contrast for certain objects. Use with MV540 devices (MLFB: 6GF3540-0CD10, -0GE10) is intended, ensuring direct integration into existing systems.

Functions and Equipment in Detail
The ring light features LED lighting with a luminous intensity of 618 Nm, providing sufficient brightness for most inspection tasks. The illumination range reaches up to 120 cm, offering adequate reach for many industrial applications. An integrated cross-polarizing filter reduces unwanted reflections and glare that could interfere with image capture. This improves image quality and enables more precise evaluation of captured images. The device comes with mounting material for secure attachment to the respective device.

Technology Explained Simply
Lighting is provided by LEDs, ensuring long service life and high light stability. The red color of the light is produced by special filters or LED chips and is optimized for use in industrial image processing. The cross-polarizing filter works on the principle of polarization filtering: it blocks light polarized in a specific plane, thereby reducing reflections on smooth surfaces. The luminous intensity of 618 Nm measures light output and affects object visibility in the image. The maximum illumination range of 120 cm defines the area where the light is still intense enough to enable clear image capture.

Compatibility and Accessories
The ring light is specifically designed for MV540 devices (MLFB: 6GF3540-0CD10, -0GE10) and is used in conjunction with these systems. For protection of the ring light and to prevent damage during mounting or operation, the use of a protective tube (MLFB: 6GF3540-8AC11) is recommended. This protective tube serves as mechanical protection and can be optionally mounted to shield the device from mechanical impacts or contamination.

Mounting and Installation
Mounting is done using the included mounting material, enabling secure attachment to the MV540 device. The positioning of the ring light is directly on the device, with alignment and distance to the inspected object adjusted according to the specific application.

Advantages in Operation
The combination of red LED lighting and cross-polarizing filter ensures high image quality for surface and material inspection. Even illumination minimizes shadows and reflections, increasing the reliability of image processing. Integrated mounting allows for quick and easy installation, accelerating commissioning. Use with MV540 devices ensures optimal compatibility and seamless integration into existing systems.
