LED signaling technology makes processes safer and more transparent

Clearly visible signals & process safety

LED signaling technology delivers instantly visible, unambiguous information for operators, maintenance, and automation systems. This improves safety, speeds response times, and reduces operating errors.

Industrial-rated & reliable in operation

LED signal lights from LED2WORK are rugged, vibration-resistant, and built for industrial environments. Even in 24/7 operations, signals remain stable, highly visible, and extremely reliable.

Efficient, flexible & future-ready

Modern LED signaling technology supports connected manufacturing through low energy consumption, long service life, and flexible control. Ideal for machines, systems, and automated workflows.

 

Reference customers & application areas

Logistics & Intralogistics

Smart signaling for automated material handling

Intralogistics covers all internal material and goods movement within a facility—from receiving and conveyor systems to sorting, order picking, and shipping. In modern logistics centers, these processes are increasingly automated and AI-driven, for example through autonomous vehicles (AGVs/AMRs), intelligent sortation systems, and adaptive material flow.

In such highly dynamic environments, clear visual signaling is critical to instantly communicate machine status, travel clearance, faults, or transfer points—clearly understandable for both people and systems.

Typical requirements:
Long-distance visible status indicators in large facilities, clear color coding for travel clearance and fault conditions, synchronization with automated systems (AGVs, conveyor systems), flicker-free light quality for vision systems, rugged construction for 24/7 operation, flexible integration into modern control architectures.

LED2WORK solution:
IO-Link-capable signal lights for direct connection to automated logistics systems, flexible configuration of colors and states, clear visualization of travel paths, transfer points, and system status, scalable concepts from individual stations to entire logistics centers. Our solutions have also proven themselves in large-scale intralogistics projects, including highly automated distribution centers.

Recommended lights:

TUBELED_25 RGB-W & IO-Link for dynamic status indication on conveyor and sortation systems
DOMELED 50 / 90 IO-Link for 360° status signaling in transfer and traffic zones
SIGNALED RGB/W for clearly visible status at individual stations
TUBELED_40 II RGB-W for combined illumination and status signaling on logistics systems

Machine Status & Visual Escalation Systems

Transparent equipment status for maximum productivity

Unlike classic signaling, where individual states are displayed, the focus here is on active process monitoring and escalation. Downtime, deviations, and faults are made visible in real time and automatically communicated, enabling faster response and minimizing production losses.

Typical requirements:
Real-time status indicators for machines and lines, clear escalation logic (e.g., green/yellow/red), visualization of downtime and deviations, clear assignment to lines or zones, integration into higher-level systems (e.g., MES/OEE), flicker-free displays with long-distance visibility, reliable 24/7 operation.

LED2WORK solution:
IO-Link-based status lights for direct integration into modern automation architectures, flexible configuration of colors and states, centralized diagnostics, and scalable concepts—from individual machines to entire production lines. This turns signaling from a simple display element into an active control tool.

Recommended lights:

TUBELED_25 RGB-W & IO-Link for dynamic line and machine status
DOMELED 50 / 90 IO-Link for highly visible escalation indicators
SIGNALED RGB/W for local status indication at individual stations
TUBELED_40 II RGB-W for combined task and status lighting directly on the machine

Classic Signaling

Clear visual status indication for machines, systems, and processes

In production environments, unambiguous visual signaling is critical for safe operations and fast response. Operating states, faults, or process steps must be instantly recognizable at a glance — even from farther away or under changing lighting conditions.

Typical requirements:
Highly visible status indicators, clear color coding (RGB/RGB-W), quick recognition from different viewing angles, rugged construction for industrial environments, easy integration into existing equipment, reliable continuous duty operation, future-ready communication.

LED2WORK solution:
LED2work is one of the technology leaders in IO-Link-capable signal lights. Our solutions enable direct, bidirectional communication with the controller — including parameterization, diagnostics, and real-time status monitoring. This is complemented by high-performance analog versions for classic applications. The result is flexible signaling concepts for both modern and legacy systems.

Recommended lights:

SIGNALED II RGB/W for clearly visible machine and process status
TUBELED_25 RGB-W & IO-Link as a linear status indicator with direct controller connectivity
DOMELED 50 / 90 for 360° all-around visibility, also available as an IO-Link variant for smart status communication
