Machine vision LED light source performance advantages and categories

June 14, 2023

Machine vision has three technical advantages: acquisition technology, processing technology and motion control technology. The choice of visual light source is to obtain a high-quality, high-contrast image by distinguishing the measured object from the background as much as possible. Moreover, the correct choice of visual light source directly affects the success or failure of the system, processing accuracy and speed.

Type of machine vision light source

The ideal light source should be bright, uniform, and stable. There are three main sources of light used in the vision system: high-frequency fluorescent lamps, fiber-optic halogen lamps, and LED (light-emitting diode) illumination.

1. High-frequency fluorescent lamp: The service life is about 1500-3000 hours. Advantages: good diffusibility, suitable for uniform illumination over large areas; disadvantages: slow response, darker brightness;

2. Fiber-optic halogen lamp: The service life is about 1000 hours. Advantages: high brightness, disadvantages: slow response, almost no change in brightness and color temperature;

3. LED lamp: The service life is about 10000-30000 hours. It can use multiple LEDs to achieve high brightness. At the same time, different shapes can be combined, the response speed is fast, and the wavelength can be selected according to the application.

LED light source performance advantages

1, can be made into various shapes, sizes and various illumination angles;

2, can be made into various colors according to needs, and can adjust the brightness at any time;

3. Through the heat sink, the heat dissipation effect is better and the brightness is more stable;

4, long service life (about 30,000 hours, longer service life);

5, the reaction is fast, can reach the maximum brightness in 10 microseconds or less;

6, the power supply with external trigger, can be controlled by computer, the starting speed is fast, can be used as strobe light;

7. LEDs with low operating cost and long life will show greater advantages in terms of overall cost and performance;

8, according to the needs of customers, special design.

LED light source color

1, the main colors: red, blue, green, white

2, other colors: orange, infrared, ultraviolet

The visual image LED visual light source has the advantages of adjustable brightness, low temperature, equalization, no flicker, no shadow, uniform brightness, color temperature and long service life. The company is committed to continuously developing new products and improving its functionality, providing a wide range of machine vision products, providing free testing and assisting in providing total solutions. It has been used in a wide range of industries. Users can choose the appropriate light source type, color and illumination according to the environment and scope of use, so that the detection system achieves the best performance and obtains the best test results.
