Measurement Solutions for Automotive Interior Lighting
Accurate and Traceable Solutions for the Specification and Testing of Interior Lighting Assemblies
Measure Automotive Interior Lighting
Control of functional and decorative lighting of automobile interior
The interior of a modern automobile is a core component in customer experience and perceived value. Now more than ever it is also an expression of the brand, its character and, therefore, by extension its owner.
Modern lighting technologies give the manufacturer a myriad of options for both functional and effect lighting. Each element must be specified and controlled, and for each additional option or level of user customisation, the challenges of specification, measurement, and control for undesired interactions increase.
The combination of different optical elements can lead to irritation in the vehicle interior if their colours are not carefully coordinated. Even colours that only slightly, yet recognizably, differ from one another, may be distracting to passengers. Generally, the various components are manufactured by different suppliers. For objective and absolute testing of the optical parameters, specific light measurement technology is therefore required at each production facility. The goal is to guarantee highly comparable and metrologically traceable measurement results whilst no reference measurement with a golden sample is required.
Konica Minolta, along with our group companies Radiant Vision Systems and Instrument Systems, produces a range of solutions for measuring lighting and lighting assemblies in development or production environments to ensure that the lighting contributes to delivering a high quality interior environment in harmony with interior materials. Solutions will ensure control of brightness, uniformity and colour of interior lighting assemblies including reading lights, footwell lighting, accent lighting and more.
Experience shows that a data driven approach allows supply chains to build relationships based on quality and consistency, reducing subjectivity, and simplifying specification and approval.
Traceable and trusted solutions for digital luminance data can greatly expedite the process of development, production, and QC testing.
Our expert teams can help to implement a system that allows all parties, from equipment manufacturer through to QC, to work in a more streamlined and consistent way.
Offering customers a global network of sales, support and expertise, Konica Minolta can deliver tested solutions to customers in the automotive industry. Our network of authorised service facilities provide ongoing maintenance and calibration of devices to minimise downtime and ensure that systems remain traceable throughout their working life.
A measurement solution from the Konica Minolta Group can ensure that you deliver a high quality interior environment in harmony with interior materials by controlling the brightness, uniformity, and colour of interior lighting assemblies including reading lights, footwell lighting, accent lighting, and more.
Benefits
- Eliminate subjectivity in specification and QC with accurate and traceable data.
- Traceable safety data by measuring store and analysing luminance data points for maximum luminance, angle, etc.
- Harmonise interior when measuring under determined light sources to specify custom interior components such as LED light strips and other illuminated elements, plastics, carpets, etc., and to detect inconstant colours early.
- Benefit from a better conformity of repeated or decentralized measurements using absolutabsolute calibrated measuring instruments. Under these conditions a realistic comparison between the incoming and outgoing inspection of suppliers and OEMs is possible, and the efficiency of the overall supply chain can be improved.
Instruments
CS-150 Luminance Colour Meter
Colorimeter for light sources and irradiated objects, display lights and signal lights. The portable tristimulus colorimeter for light sourfces and irradiated objects is commonly used to measure display lights, signal lights, and to make non-contact surgace colour measurements.
CS-200 Luminance Colour Meter
Spectrally based colorimeter for luminance measurement, including chromaticity and colour temperature. The CS-200 Chroma Meter measures luminance and chromaticity of light emitting products as diverse as large plasma displays, compact LCDs and LEDs, outdoor screens, high pressure lamps, and instrument panels.
Applications
Measurement of Boot Lighting
A portable illuminance meter can be used to verify even and appropriate illuminance levels throughout the depth and breadth of the boot to improve customer experience.
Measurement of Curved Displays
Instrument Systems developed the DMS goniometer systems specifically for characterisation of the quality of curved lighting components. All DMS systems enable the measurement of luminance, colour and contrast under different
viewing directions and operating conditions, electrooptical transfer functions (EOTF) and flicker, spectrally diffuse and direct reflection and transmission, qualification of the effects of ambient lighting and temperatures.
Measurement of Illuminance / Brightness / Chromaticity of interior lighting
Inspect and manage the illuminance, brightness, and chromaticity of automotive interior lights with a luminance meter (CS-150 / CS-200) or illuminance meter (CL-500A). Thanks to the handheld design, it is easy to measure hard-to-reach areas in the cabin, such as near the steering wheel, near the doors, under the seats, etc.
