Why Choose DL1L Series
- Continuous Uninterrupted Illumination: Designed to provide seamless linear lighting without any optical gaps. This advanced architecture allows system integrators to achieve perfectly uniform illumination spans extending up to 3000 mm for wide-field vision applications.
- Line Scan Camera Optimized: Specifically engineered to meet the stringent demands of high-speed linear vision sensors. The dense LED spacing and integrated focusing optics deliver a highly homogeneous light profile across very large inspection areas.
- Anti-Flex Support Bar: The illuminator is built directly onto a heavy-duty anodized aluminum support bar. This reinforced structural integrity prevents mechanical deformation and bending, ensuring perfectly straight optical alignment over exceptionally long production lines.
- Integrated Driver Stability: Equipped with internal Multi Constant Current Driver (MCCD) technology, the system seamlessly compensates for power supply fluctuations. This electronic stabilization guarantees constant light intensity across the entire length, enabling reliable sub-pixel analysis.
- Advanced Thermal Management: Utilizing High Thermal Transmission Material (HTTM), the robust aluminum chassis efficiently dissipates heat generated by the LEDs. This protects internal components during intensive high-duty cycles and prevents unwanted chromatic shifts over time.

The DL1L Series LED bar illuminators are precisely engineered to solve the complex challenges of large-scale machine vision applications, specifically targeting high-speed line scan cameras. Unlike standard modular lights that suffer from dark spots when joined together, this advanced series delivers uninterrupted continuous illumination up to 3000 mm without any optical gaps.
To ensure long-term mechanical reliability, the DL1L is constructed upon a specialized anti-flex aluminum support bar. Consequently, this rigid structural design effectively prevents bending over long spans, maintaining a perfectly aligned light emission along the entire inspection web.
Furthermore, consistent lighting performance is critical for accurate defect detection. For this reason, the built-in MCCD (Multi Constant Current Driver) technology makes the system immune to voltage drops, while the advanced HTTM thermal management efficiently dissipates excess heat.
Ultimately, combining high-density LED optics with a robust industrial architecture makes the DL1L Series the definitive choice for inspecting films, textiles, glass, and continuous production materials.

What inspired this series

The DL1L series was developed to address the specific technical challenges of wide-field linear inspection.
Standard linear lights often suffer from light discontinuity when multiple units are combined.
Furthermore, maintaining mechanical straightness over long spans is difficult without bulky supports. Our engineers designed a modular yet seamless architecture. This allows for continuous illumination up to 3000 mm.
Design Evolution: Ensuring Straightness and Continuity
A critical design driver was the integration of a reinforced aluminum support bar. This prevents bending and maintains optical alignment. We also prioritized thermal management.
The use of HTTM technology ensures stability in high-duty cycles. The DL1L provides the intensity required for high-speed web cameras. It eliminates the common “seams” found in tiled lighting. This family represents a solution for engineers inspecting films, textiles, and glass. It is a tool built for precision over large dimensions.
