German – LISUN Engineer Provide Free Installation and Training of LSG-1950 Goniophotometer for Automotive and Signal Lamps

In the global field of traffic lighting and special lighting manufacturing, German enterprises are renowned worldwide for their strict quality standards and exquisite craftsmanship. The customer of this cooperation is a large-scale German lighting manufacturer with decades of experience in the industry, focusing on the R&D, production and sales of traffic signals, automotive lamps, bus-specific lamps, and supporting lamps for marine and aerospace equipment. Its products are exported to many countries and regions around the world, widely used in core scenarios such as urban traffic, rail transit, and maritime shipping, and have extremely high requirements for the detection accuracy of product optical performance.

The customer learned about our optical testing equipment through the company’s official website and then took the initiative to initiate consultation, clarifying the core demand – purchasing a professional goniophotometer, focusing on the optical performance testing of traffic signals, while taking into account the auxiliary testing of automotive lamps and marine lamps, to ensure that the products meet relevant international standards and guarantee the safety and stability of terminal use. Combining the customer’s industry attributes and product characteristics, our sales and technical teams intervened immediately, conducted in-depth communication with the customer for many rounds, and accurately explored their core demands and potential needs.

The customer clearly put forward specific requirements for the equipment testing parameters, which is also the core standard for their selection of suppliers:
• first, the luminous intensity measurement range should cover 1.0cd~10⁷cd, and the illuminance measurement range should be 0.001lx~99999lx to meet the testing needs of different specifications of traffic signals;
• second, the angle accuracy should reach 0.01°, and the angle resolution should be 0.001° to ensure the accuracy of beam angle testing, which is consistent with the strict light distribution requirements of traffic signals;
• third, it should meet international and domestic standards such as ECE-R65, FMVSS108, and GB13954, and support English operation software to adapt to the operating environment of their German factory;
• fourth, the equipment should have good compatibility, capable of testing various lamps with a weight of no more than 35kg, to meet the testing needs of multiple product categories.
• In addition, the customer also proposed a clear budget range and informed us of the existing darkroom size of their factory, which is 10 meters in length, 6 meters in width and 6 meters in height, requiring us to customize the optimal equipment and darkroom planning scheme based on this size and budget.

In response to the customer’s needs, our technical team conducted a comprehensive plan demonstration and optimization. Combining the customer’s darkroom size, referring to the standard requirements of LM-79 and CIE-70, and considering that the test optical path length needs to be more than 6 times the maximum diameter of the tested lamp, we accurately planned the installation position and optical path layout of the LSG-1950 Goniophotometer for Automotive and Signal Lamps. The main equipment was installed at one end of the darkroom, and the photometric probe was fixed at the other end to ensure that the optical path length meets the testing accuracy requirement of more than 8 meters. At the same time, reasonable operating space was reserved to not affect the customer’s subsequent production and testing processes. In terms of budget control, we optimized the equipment configuration, streamlined unnecessary additional functions on the premise of ensuring that the core parameters meet the standards, which not only meets the customer’s testing needs but also strictly controls the cost, in line with their budget expectations.

After multiple rounds of plan communication, parameter confirmation and detail optimization, the customer highly recognized our professionalism, response speed and the rationality of the customized plan, and finally decided to place an order for the LSG-1950 goniophotometer. After receiving the order, our technical department immediately contacted the customer again to synchronize the equipment production progress, and communicated the darkroom pre-processing matters in advance, guiding the customer to complete the preliminary preparation work such as stray light control and temperature adjustment of the darkroom (ensuring a constant temperature environment of 25±1℃), laying the foundation for the subsequent equipment installation and commissioning.

After the equipment was produced and successfully delivered to the customer’s factory, we immediately sent an experienced team of engineers to Germany to carry out equipment installation, commissioning and operation training. The engineering team efficiently completed the assembly and calibration of the equipment in strict accordance with the standardized process, ensuring that all parameters of the equipment meet the customer’s requirements, the stray light is controlled below 0.1%, and the testing accuracy reaches 2% (under standard light source). During the training, combining the customer’s product characteristics, the engineers demonstrated the equipment’s operation process, parameter setting, data collection and analysis methods on site, guided the customer’s employees to master the daily operation and maintenance skills of the equipment by hand, and answered various practical questions. Below are the photos sent by the client after the successful installation and training of the laboratory:

The entire installation and training process was efficient and orderly, completing all work in only 3 working days, far exceeding the customer’s expectations. The customer highly praised the professional quality and response speed of our engineers as well as the performance of the equipment, clearly stating that the equipment is easy to operate and accurate in testing, fully meeting their production and testing needs, effectively solving the previous problems of inaccurate and inefficient optical performance testing of products, and providing strong support for their product quality control.

This successful cooperation with a large German traffic lighting enterprise not only demonstrates the product strength and professional advantages of our LSG-1950 goniophotometer but also further expands the influence in the overseas market. In the future, we will continue to focus on the optical testing field, deepen industry needs, provide more accurate, efficient and customized testing equipment and services, help global lighting manufacturers improve product quality, and empower the high-quality development of the industry.
