Where Will LED PCBs and DOB Modules Go After the 2026 Frankfurt Light + Building Fair?

If there’s one way to summarize the 2026 trend: Lighting products are evolving from light sources into system-level nodes.

1. From Driver-less to Re-integrated Systems：

DOB (Driver On Board) was originally about: cost reduction, simplicity and eliminating external drivers. Now, that logic is shifting. Under electrification and smart connectivity, DOB is no longer just “driver-less”, but is being re-integrated with: control (MCU) , communication (BLE / DALI / Zigbee) and sensors. DOB is becoming a lightweight driver + control node.

2. The Role of LED PCBs is Changing:

Historically, LED PCBs were: carriers, thermal solutions and cost-driven components. Now they are evolving into: standardized modules, replaceable units and system interfaces. Especially in Europe, modularity and serviceability are becoming essential. PCBs are no longer just boards -- they are platforms.

3. DOB Module will Split into Two Distinct Paths:

In the coming years, DOB will likely split into two categories: one is Cost-driven DOB for low-end markets, focused purely on cost with simple function. The other is Smart DOB integrated dimming and communication, support system access, focused on commercial and smart lighting. The middle ground will shrink.

4. Technical barriers are quietly rising.

DOB used to be simple. Future DOB will be more complicated.

Key shifts will include: electrolytic-free designs (longer lifetime), stricter EMI/EMC requirements, stronger thermal design and better power quality (PF / THD). DOB is shifting from a cheap solution to an engineering-driven product.

5. A More Fundamental Shift

A deeper transformation is happening in lighting industry: from luminaire = light source + power supply to luminaire = node. This node can emit light, sense, communicate and connect to energy systems. LED PCBs and DOB modules are located at the core of this transformation.

This is not just a product upgrade — it’s a role shift: from component supplier to system module provider. In the next 3–5 years, competition will not just be about cost, but about: integration, standardization, and system-level understanding.
