OSRAM LINEARlight LM01A-Y1 – Yellow Rigid LED Module 10 V (32 LEDs, 4 W, 587 nm)
The OSRAM LINEARlight LM01A-Y1 is a rigid 10 V DC LED module with 32 diodes emitting yellow light (λdom 587 nm) . Designed for professional linear lighting and signage applications, it offers a 120° beam angle and a typical luminous flux of 69 lm per panel at 4 W, combining uniformity and low heat generation in a compact form factor. It can be divided into 4-LED units (56 × 10 mm) without loss of functionality and up to 3 modules can be daisy-chained from a single power supply, always in parallel . It is optimized for use with OPTOTRONIC 10.5 V DC constant voltage sources and supports PWM dimming via compatible control interfaces (e.g., OT DIM). Its Ø 4 mm mounting holes facilitate secure installation in profiles and raceways, while the panel (448 × 10 × 4 mm) fits into confined spaces.

Frequently Asked Questions
Can I cut the plate?
Yes. It can be cut into 4 LED modules (56 × 10 mm) at the indicated marks, maintaining functionality in the resulting pieces.
How should I connect it?
Parallel connection only. Series connection is not recommended. Up to 3 modules can be daisy-chained from each power point, respecting the voltage drop and current capacity of the system.
Which driver do I need?
A 10.5V DC constant voltage driver from the OPTOTRONIC range is the recommended choice for stability and adequate protection.
Can it be regulated?
Yes. With OT DIM (0–10 V) control interfaces that generate PWM at the output for smooth and consistent dimming.
Is it suitable for humid environments?
The board does not have a factory-applied conformal coating. For humidity/dust, it must be housed in a suitable enclosure or conformal coating must be applied according to the manufacturer's recommendations.
Installation recommendations
- Use screws with insulating washers to protect the printed circuit board traces.
- Observe polarity and safety distances; take ESD precautions during assembly.
- If the power supply can exceed 2 A , incorporate fast-blow fuses into the design.
- For outdoor or harsh environments, protect by means of conformal coating or housing with an appropriate degree of protection.
