LED Backlight Illuminators BL2 Series

Why Choose BL2 Series

• High-Density LED Matrix: Built-in integrated lens creates a direct and homogeneous light beam, with a special fixturing mask ensuring uniformity of LED mounting spacing across the entire emission area.
• MCCD© Current Control: The integrated Multi Constant Current Driver regulates LED current for consistent homogeneity and stability of light emission throughout continuous industrial operation.
• HTTM© Heat Dissipation: High Thermal Transmission Material between LEDs and housing keeps operating temperature constant, stabilises brightness and significantly extends LED service life.
• Compact 17.5 mm Profile: A one-piece anodised aluminium block with flush top surface and bottom-side fixing fits into tight machine spaces where side brackets cannot be used.
• Industrial M8 Connector: Threaded M8 3-pin connector with flexible grommet enables easy assembly, quick disconnection for maintenance and reliable cable management in constrained spaces.
• Reverse Polarity Protection: Internal circuits are fully protected against reverse polarity of the supply voltage, preventing damage from incorrect power cable connection during installation.
• 21 Standard Sizes: From 50 × 50 to 300 × 300 mm, in neutral white or infrared, every BL2 is delivered with its own 48-hour test certificate.

The BL2 series delivers high-intensity LED backlight illumination optimized for machine vision and automated optical inspection. Featuring a high-density LED matrix with integrated lens, these compact illuminators provide exceptional luminous uniformity for sub-pixel edge detection, dimensional measurement, and surface defect detection.

The integrated MCCD© Multi Constant Current Driver ensures automatic current regulation and light stability, while HTTM© thermal management extends LED operating life in continuous industrial use. With PWM dimming, 24 Vdc remote control, and an M8 vibration-resistant connector, the BL2 integrates seamlessly into OEM machines and robot-guided pick-and-place, pharmaceutical packaging inspection, and label verification systems.
