Production & Quality
Design Development
LIGMAN are 100% dedicated and focused on the quality and design of our luminaires. We select only the highest grade of components and design their integration within fixtures using our many years of experience and technical know-how. We are continuously improving and evolving new ranges, with new inspirations, unique designs, a wider range of finishes and the latest innovative technologies.
Design & Prototyping
LIGMAN products are designed using only the latest CAD/CAM software available in the marketplace and using a variety of high-tech tools to create new prototypes for testing and final production tooling.
The product design engineers, optical design engineers, testing engineers and production engineers work together to develop all new luminaires with the highest quality, highest efficiency and optimal value for our customers.
Materials
LIGMAN uses high corrosion resistance, extremely low copper content LM6 aluminum alloy for our high-pressure diecast luminaire body castings. All fixtures are finished using our superior powder coating process, with double powder coating also offered as an option if desired for extreme environments.
In addition, for key internal components such as LED heatsinks we use ADC12 aluminium alloy. This material is used in the automotive industry for mechanical strength and excellent thermal dissipation, ideally suitable for low and high ambient temperature applications. LIGMAN also verifies heatsink designs through thermal imaging techniques before commencing commercial production. This enables us to ensure less than 10% lumen depreciation at 50,000 hours for all our products.
Testing Laboratories
We built the laboratory center to ensure our products exceed the design and quality requirements set out by international standards. All measuring tools are consistently serviced and updated to the latest technology, with additional measuring implements introduced to cover more metrics.
Our state of the art laboratory has been inspected and tested in accordance with international testing standards.
Each of our products are carefully tested with the following luminaire standard tests in accordance with the international standards requirements:
– Electrical Testing
– Mechanical Testing
– Resistance to Dust, Solid Objects and Moisture
– Endurance Tests and Thermal Tests
– Salt Spray Testing
– Photometric Testing
