Built for the UK LED Lighting Supply Chain
The UK LED lighting market has transformed rapidly over the past decade and the pace of change is not slowing. Government energy efficiency mandates, the continued transition away from legacy light sources, and the growing integration of smart lighting controls across industrial, commercial, and automotive applications have created sustained demand for precision LED electronics.
At Arkle Electronic Systems, we manufacture electronics for LED lighting OEMs across industrial and automotive applications. Our PCB assembly, box build, and cable harness capabilities cover both the light engine boards that carry and drive the LEDs, and the driver and control electronics that manage power, switching, and system integration. With over 50 years of electronics manufacturing experience and a UK manufacturing facility in Stevenage, Hertfordshire, we are well positioned to support LED lighting programmes that require a reliable, quality-accredited UK manufacturing partner.
Our LED Lighting Sector Experience
Arkle's LED lighting customer base is deliberately focused rather than broad. We work in depth with customers in two distinct areas of the market, each with its own specific technical requirements, and we build the understanding of those requirements into every programme we take on.
Industrial Lighting Controls for High-Speed Production and Assembly Lines
Industrial lighting control electronics for high-speed production and assembly environments represent one of the most demanding applications in the LED sector. These systems must deliver precise, repeatable light output at switching speeds that keep pace with the production line, with the reliability and longevity that continuous industrial operation demands.
Machine vision systems, inspection stations, and automated assembly lines depend on lighting control electronics that can trigger consistently and accurately, with minimal variation between cycles and no tolerance for failures that would halt production. The electronics behind these systems, including driver boards, control interfaces, and power management assemblies, must be built to the quality standards that industrial automation requires: full traceability, consistent performance across production batches, and the documentation that supports maintenance and system integration on the line.
Arkle manufactures these electronics with the process discipline and inspection rigour that industrial customers expect. IPC-A-610 Class 3 assembly acceptability, AOI and X-ray inspection, and full build documentation are standard across our industrial lighting control builds.
Automotive LED Lighting: On-Road, Off-Road, and Military Applications
Automotive LED lighting electronics operate in one of the broadest environmental envelopes of any LED application. On-road vehicles face wide temperature cycling, vibration from engine and road inputs, moisture exposure, and the electrical noise of a 12V or 24V automotive power system. Off-road vehicles add dust, mud, impact, and more aggressive vibration profiles. Military vehicle lighting extends the requirements further still, with ruggedisation, EMC, and in some applications specific military standards coming into play.
Arkle manufactures LED lighting electronics for an automotive customer whose product range spans on-road and off-road vehicle lighting, and who is developing military vehicle lighting applications. This breadth of application within a single customer relationship reflects the versatility of our manufacturing capability and our ability to scale with a customer's product range as it develops.
Automotive and Military LED: The Manufacturing Requirements
Automotive LED electronics must meet the environmental qualification requirements of the vehicle market. Vibration resistance to ISO 16750-3, thermal cycling across the operating temperature range of the vehicle, and moisture protection appropriate to the installation location are all manufacturing considerations that affect product reliability in the field.
For military vehicle lighting applications, additional requirements apply. EMC compliance to DEF STAN 59-411 or equivalent, ruggedisation for the shock and vibration profiles of military vehicle operation, and the documentation and traceability discipline of defence programme supply chains are all considerations that Arkle's manufacturing processes are equipped to support. The crossover between automotive and military lighting is a growing area of the market, and one where Arkle's experience across both sectors provides genuine value.
The Technical Challenge of LED Lighting Electronics
Professional and industrial LED electronics sit at the intersection of high-precision light engine design and power electronics. The manufacturing decisions made at every stage affect the performance and longevity of the finished product in ways that matter to the end user, whether that is a production engineer watching for inspection failures on a high-speed line or a fleet operator expecting vehicle lighting to last the life of the vehicle.
LED Light Engine Boards and Thermal Management
The LED light engine board carries the LEDs themselves and acts as the primary thermal pathway from LED junction to heatsink. For most commercial and industrial applications the board uses a Metal Core PCB with an aluminium base plate typically 1.0 to 3.0mm thick. The thermal conductivity of the dielectric layer between the copper circuit and the aluminium base determines how effectively heat moves from the LED junction through the board. Junction temperature management is critical: for every 10 degrees Celsius above rated junction temperature, LED lifespan approximately halves.
Solder mask reflectivity is a further consideration that is often overlooked at the assembly stage. White solder mask on LED boards reflects spilled light back through the optic, improving luminaire efficacy. Standard white masks can lose their reflective properties during reflow soldering. Arkle specifies solder mask materials that retain their reflectivity after the thermal cycling of the assembly process.

Driver Board Electronics
The driver converts mains or vehicle supply voltage to the constant-current output the LED engine requires, and provides the control interface that allows the system to respond to switching commands. For industrial lighting control applications the switching speed, consistency, and immunity to electrical noise on the supply are the critical parameters. For automotive applications the driver must cope with the wide voltage range and transient events of the vehicle electrical system, from cold-start voltage dips to load-dump transients, without compromising LED performance or driver reliability.
Moisture Sensitivity Management
LEDs and many driver board components are moisture-sensitive devices classified under IPC/JEDEC J-STD-033. Incorrect handling before assembly, including exposure to ambient humidity beyond the rated floor life, causes moisture absorption into the package which can result in delamination or internal damage during the high temperatures of the reflow process. Arkle manages moisture-sensitive components to J-STD-033 throughout storage and assembly, with controlled storage in sealed bags, floor life monitoring, and baking procedures where required.
Conformal Coating for
Demanding Environments
LED electronics destined for industrial or automotive applications require conformal coating appropriate to the installation environment. For automotive applications this means coating chemistry that maintains flexibility and adhesion across wide temperature ranges and through repeated thermal cycling. Silicone coatings are well suited to wide-temperature automotive applications. Acrylic coatings are used where repairability is a consideration. All coating is applied and inspected to IPC-CC-830C standards with UV verification of coverage.
Our LED Lighting Manufacturing Capabilities
Standards and Quality
Arkle holds ISO 9001:2015 quality management and ISO 14001:2015 environmental certification. Our assembly processes reference IPC-A-610 for assembly acceptability, IPC/WHMA-A-620 for cable and harness, and IPC J-STD-001 for soldering. LED component moisture sensitivity management follows IPC/JEDEC J-STD-033. No additional sector-specific standards are currently required by our LED lighting customers beyond these.
UK-based manufacturing means direct access to our engineering team, shorter supply chains, and faster response to design changes. Our 50-plus years of electronics manufacturing experience across industrial, automotive, defence, and other high-reliability sectors gives LED lighting OEMs a manufacturing partner who brings broader sector knowledge to every build.
We work with customers from prototype through to production, scaling with the programme and maintaining consistent process discipline at every stage.
