OSRAM LINEARlight LM01A-B1 - Blue Rigid LED Module 10 V (32 LEDs, 4 W, 470 nm)
The OSRAM LINEARlight LM01A-B1 is a rigid , constant-voltage 10V DC LED module with 32 blue LEDs (λ 470 nm) and a power rating of 4W . Designed for linear lighting and professional signage, it offers a 120° beam angle and a typical luminous flux of 10 lm , ensuring uniformity in contour lighting, light guide injection, and backlighting applications. The narrow board format ( 448 × 10 × 4 mm ) incorporates Ø 4 mm mounting holes for quick installation with standard screws or hardware. It can be cut into 4-LED segments (56 × 10 mm) and connected in parallel only , with the possibility of daisy-chaining up to 3 modules per power point. It is optimized for use with OPTOTRONIC 10/10.5V DC power supplies and supports PWM dimming via OT DIM control units on the secondary side.

Frequently Asked Questions
Can I cut the module?
Yes, in 4 LED units (56 × 10 mm) in the indicated brands.
How should I connect it?
Parallel only . Up to 3 modules can be connected in series from the same power supply point, respecting the cable cross-section and voltage drop.
Which driver should I use?
OSRAM OPTOTRONIC range 10/10.5V DC constant voltage power supplies, which incorporate protections and are optimized for these modules.
Can the brightness be adjusted?
Yes, by means of OT DIM dimming units (1–10 V) on the secondary side, which modulate the module's power supply by PWM .
What environmental considerations are there?
The board does not have a conformal coating; for moisture or dust, it must be protected with a suitable enclosure or coated according to the manufacturer's recommendations.
Installation recommendations
- Use insulating washers with screws to avoid damaging the PCB traces.
- Respect polarity and take ESD precautions during assembly.
- If the power supply can deliver more than 2 A , include fast-blow fuses in the wiring design.
- For environments with humidity/dust, provide an enclosure with a degree of protection or a transparent, UV-resistant conformal coating .
