Three-color lamp

I. The Functions of the Three-color Light 
The three-color lamp (also known as "signal indicator lamp", "alarm indicator lamp", or "machine tool three-color lamp") is an industrial signal device used for displaying equipment status and giving warnings. It is widely applied in various automated production lines, CNC machines, hydraulic equipment, packaging machinery, and other scenarios. 
The main purposes include: 
Equipment operating status display 
Green light on: The equipment is operating normally or is in use; 
Yellow light on: The equipment is in standby, debugging or warning state. 
Red light on: The equipment has malfunctioned, there is an alarm or an emergency stop. 
Production Line Monitoring and Management
In the automated production workshop, the three-color lights provide remote signals for indication, facilitating operators and inspectors to quickly understand the equipment status and enhancing management efficiency. 
Safety warning function
It provides visual alarm prompts for abnormal equipment conditions, electrical faults, pressure or temperature over-limit situations, thereby reducing errors and safety accidents. 

Human-machine interface assistance
Combined with PLC and industrial control systems, it enables real-time status feedback and is an indispensable visual component in intelligent manufacturing. 
II. Main Features of the Three-color Light 
Three-color integrated design
The red, yellow and green lights are integrated into one unit, saving installation space and ensuring clear signals with high status recognition. 
Multiple light sources are available.
It uses high-brightness LED light sources, featuring high brightness, long lifespan, and low energy consumption. It supports various alarm modes such as constant illumination and flashing. 
Installation methods are flexible
You can choose from options such as vertical installation, wall-mounted installation, or installation on the top of the machine tool, meeting the needs of different industrial equipment. 

Supports multiple signal inputs
Can be combined with PLC, sensors, controllers, etc. to achieve automatic control and signal switching. 
The casing is sturdy and durable.
The lamp body is mostly made of ABS, aluminum alloy and stainless steel, and has excellent dustproof and waterproof properties (up to IP54~IP65 level). 
Highly scalable
Optional buzzer and sound-light alarm module can be equipped to enhance the alert effect. 
Wide range of applications
Applicable to: 
Automated assembly line 
CNC numerical control machine tool 
Hydraulic equipment 
Robot workstation 
Packaging machinery, inspection equipment 
Warehousing and Logistics System
