An automation and control leader in Spain for more than 40 years, Contaval designed the industrial lighting brand Lumher to fill a critical gap in manufacturing environments. Machine vision, automated quality control, high-precision robotics – they all require robust, specific lighting systems that didn’t exist in the market until Lumher.
“Generic, standard lighting simply wasn’t enough,” said César Elorriaga, Technical Director. “Our mission is to provide engineering firms, machine builders and integrators with a lighting solution that truly solves their problems.”
Why Lumher Stands Out
Contaval draws on decades of experience in the industrial field and a deep understanding of where standard lighting falls short. As a result, Lumher products are engineered to meet the demands of modern manufacturing with reliability and peak performance.
“Every stage of our design and production in Spain is under rigorous quality controls,” said Javier González, Head of R&D Department. “Using high-resistance materials, Lumher lights are made to survive tough industrial conditions and keep maintenance costs low.”
Custom solutions are a defining feature of the brand and have been since day one. While standard lighting often leads to glare and imbalanced illumination, Lumher’s systems are tailored for high-precision environments. Every luminaire is built to deliver the uniform, contrast-rich light that computer vision systems need to function perfectly, resulting in fewer false rejections and greater efficiency on the production line.
Company Growth and Recognition
Lumher is a recipient of the Innovative SME Seal from the Spanish Ministry of Science and Innovation. The brand has focused more on machine vision products over the last few years, developing versatile and competitively priced solutions. This strategic focus has driven growth with international customers such as Ford, Tesla, Mitsubishi, Istobal and Irizar.
Strategic Advantage in Spain
Having a product manufactured in Spain, with European certifications and standards, allows Lumher to supply products efficiently to America and Europe. These are the company’s primary markets and where machine vision applications are expected to grow in the coming years. Lumher also collaborates with local customers and expert technological partners in the development and improvement of machine vision products.
Lumher Machine Vision Lighting
In automated inspection and quality control, LED machine vision lighting is essential for accurate and reliable image capture. Consistent, uniform illumination enhances visibility and ensures high-resolution images for detecting defects, measuring precisely and improving overall product quality.
LED lights can be customized for specific wavelengths, like infrared or ultraviolet, and adjusted in intensity, direction or strobe operation to match different production and inspection needs. With a compact size and low power consumption, they are easy to integrate into machine vision systems.
At AutomationDirect
AutomationDirect offers a wide range of Lumher vision lighting fixtures, including bar, ring, flat and spot lights.
· Bar Lights: Available in two series—PD (standard power) and FD (high-power, emits twice the light from the same package). Both come in semi-diffuse and ultra-diffuse lighting angles, with white, red and infrared models.
· Ring Lights: Offered in semi-diffuse and ultra-diffuse angles, with white or infrared LED options.
· Flat Lights: Provide semi-diffused lighting angles and emit bright, uniform white light.
· Spotlights: Deliver a narrow 6° lighting angle for highly focused light at varying distances.
All Lumher lights are IP65 rated, operate on 22.8–25.2 VDC and are built for continuous use. Select models also support strobe operation. A wide range of mounting accessories makes installation simple, and everything is backed by a 3-year warranty.
“Choosing Lumher is about more than lighting up a workspace,” added Bernardo Álvarez, Head of Lighting & Vision Department. “It means gaining a competitive advantage with a partner that understands industrial challenges and designs precise, reliable solutions to overcome them.”
