Selection strategy for machine vision light sources and suggestions for customizing LED light source

Selection strategy for machine vision light sources and suggestions for customizing LED light sources
In machine vision systems, the selection and customization of light sources are crucial to the performance of the system. Here are the best selection strategies for machine vision light sources and suggestions for customizing LED light sources:
I、 Machine Vision Light Source Selection Guide
1. Understand application requirements:
-Object type: Different surface characteristics of objects, such as reflectivity and color, may require different light sources.
-Testing requirements: The details of identification, measurement, or inspection have different requirements for the type and intensity of the light source.
-Environmental conditions: The light source needs to adapt to different environmental conditions, such as light, temperature and humidity.
2. Light source type:
-Circular light source: suitable for uniform illumination, reducing shadows, commonly used for surface defect detection.
-Backlight source: shining from the back of the object, highlighting the outline of the object, suitable for detecting the edges or holes of the object.
-Linear light source: used to highlight surface features of objects, such as uneven surfaces.
-Point light source: suitable for high contrast detection tasks, typically used for precise measurements and high-resolution imaging.
3. Brightness and uniformity of the light source:
-Ensure that the brightness of the light source is sufficient to provide sufficient contrast.
-Uniform lighting can reduce image distortion caused by uneven lighting.
4. Color and wavelength of light source:
-Choose a light source suitable for the color of the object being detected, such as red, green, blue, etc.
-For certain specific applications, such as fluorescence detection, specific wavelength light sources may be required.
5. Control method of light source:
-Switch control: Simple switch operation.
-Dimming control: Adjust the brightness of the light source to meet different detection needs.
-Flash control: It can reduce motion blur during high-speed shooting.
6. Installation method of light source:
-Choose the appropriate installation method based on the actual machine vision system and spatial conditions, such as fixed installation, adjustable installation, etc.

II、 Suggestions for customizing LED light sources
1. Clarify requirements:
-Determine the specifications of the light source, such as light intensity, spectral range, emission angle, etc.
-Understand the installation environment and space limitations of the system.
2. Choose the appropriate LED model:
-Select the LED model based on the type of light source, such as white LED, infrared LED, etc.
-Consider the lifespan and stability of LEDs.
3. Design and heat dissipation of light source:
-The design should consider heat dissipation issues to ensure the stability of LED under high brightness.
-Use heat sinks or other heat dissipation solutions to extend the lifespan of LEDs.
4. Customized services:
-Looking for suppliers with professional technical capabilities to provide customized services.
-Conduct sample testing to ensure that the customized light source meets practical application requirements.
5. Compatibility and maintenance:
-Ensure that customized LED light sources are compatible with existing machine vision systems.
-Provide relevant technical support and maintenance services.
By considering these factors comprehensively, you can select and customize the most suitable light source for your machine vision system, improving the detection accuracy and efficiency of the system.
