As a signal lamp commonly used in industrial production, the three-color lamp of machine tool is widely used in machine tools, automation equipment and production lines, etc., to indicate the working status of equipment, alarm and remind operators. With the continuous improvement of industrial automation, the performance and function requirements of machine tool tricolor lamps are getting higher and higher. This article will analyze the three-color lamp of the machine tool in detail from two aspects: color transformation mechanism and working principle.
1. Color transformation mechanism.
The color change mechanism of the tri-color lamp of the machine tool is its core part, which determines whether the signal light can accurately indicate the working status of the equipment. Generally speaking, the color change mechanism of the tri-color lamp of the machine tool is realized by LED lights and circuit control.
1.LED lights.
The three-color lamp of the machine tool generally uses the LED lamp as the light source, which has the advantages of long life and high brightness, which can meet the requirements of the industrial environment. The color of the LED lamp mainly includes red, yellow and green, which corresponds to the working state represented by the three-color light of the machine tool.
2.Circuit control.
The color change of the tri-color lamp of the machine tool is realized by circuit control. The circuit control can control the on/off of the LED lamp and the color change according to the input signal, so as to realize the control of the three-color lamp of the machine tool. This kind of circuit control is generally realized by controllers such as microprocessors or PLCs, which has the advantages of high flexibility and fast response.
Second, the working principle.
The working principle of the tri-color lamp of the machine tool includes three aspects: signal input, color transformation and brightness control.
1.Signal input.
The signal input of the tri-color light of the machine tool usually comes from the machine itself or from an external controller. The equipment itself will send signals such as working status and alarm to the three-color light of the machine tool, and the external controller can also send the corresponding signal to control the three-color light of the machine tool through the interface.
2.Color transformation.
When the tri-color lamp of the machine tool receives the signal, according to the type and state of the signal, the LED lamp is controlled to turn on and off and change the color through the circuit. For example, when the machine is working normally, the tri-color light of the machine is green;When the machine fails, the machine tricolor light is shown red.
3.Brightness control.
In addition to the color change, the machine tool tri-color lamp also needs to control the brightness to adapt to the requirements of different environments. The brightness control is generally realized by the LED driver circuit, which can be automatically adjusted according to the intensity of the ambient light to ensure that the three-color light of the machine tool has good visibility in various environments.
Epilogue. The tri-color lamp of machine tool is an indispensable equipment in industrial production, and its color transformation mechanism and working principle determine its application effect and reliability at the production site. With the improvement of industrial automation, the requirements for machine tool tri-color lamps are getting higher and higher, therefore, it is one of the current research hotspots to continuously improve and perfect the technology and performance of machine tool tri-color lights. It is believed that with the development of technology, the three-color lamp of machine tools will play an increasingly important role in industrial production.
