Cutoff Measurement System

Company synopsis Pleiades Instruments is an optoelectronic system manufacturer, it designs and manufactures specific measures systems. By designing high performance devices, our team allows you to meet the standards and suits your specific needs. Our devices are used by automotive lighting industry for the development and the production testing of different types of products such as rear or head lamps. Our products enable an analysis of the spatial distribution and photometric properties. They will help you for the certification of your devices, according to different standards (SAE, ECE, Japan,...

Photometry and measurement Photometry Photometry is the science of the measurement of light, in terms of its perceived brightness to the human eye. Several photometry units can be used depending on what people want to study. Symbol Luminous Intensity Luminous Flux Candela per square meter [cd/m²] For Automotive lighting industry, the most common unit is the candela. It is the SI base unit of luminous intensity –power emitted by a light source in a particular direction, weighted by the luminosity function: V(λ)-. Luminosity Function This function, determinated in 1924 by the CIE, represents the...

Illuminance is the total luminous flux incident on a surface, per unit area. It is a measurement of the intensity of the incident light. Illuminance is measured in lux. ф=I.Ω L=I/A Luminosity Intensity polar graph When the source can be considered as a point –for example a star- we have the formulas –if detector is perpendicular to the beam-: Photometric standards Photometric standards are defined according to geometries (Plane or Sphere), Units (Lux or Candela) and distances (10m for signaling and 25m or lighting). θPlane Source Surface , The conversion between plane and sphere is given by:...

System structure Cutoff Measurement System has been conceived and designed to measure and analyze temporal changes of cutoff position for headlamps. A cell detector, placed at 10 m (or 25m) in front of the product and moving along the vertical axis, provides...

Cutoff Measurement System Cutoff Measurement Systems with a mobile cell allow measurement and qualification of related products according to different standards (SAE, ECE and Japan) on 10m or 25m. Thanks to this device, useful for Research and Development as well as production in the automotive lighting industry, our customers can test and certify many different products. Our Cutoff Measurement System has many assets: Stand alone system. Large measurement range: 0 to 2750 lux High photometric resolution. High quality and repeatability of the measurements. Instant measurement. Easy to use software,...

Software: ALPES Our system is delivered with our fully applicative software called ALPES (Automotive Lighting Photometric Equipment Software). ALPES is an application used for controlling and running the photometric systems manufactured by Pleiades Instruments. It offers a user friendly and simplified user interface for operators in production mode, or a fully customizable software for administrators and Research & Development users. ALPES is used for all the systems sold by Pleiades Instruments: goniophotometer, multi-cells, and cutoff systems and for different products: signaling and lighting....

Our Cutoff Measurement Systems may be certified by the French certification body UTAC to fulfill customer requests. UTAC is the Technical Union for the Automobile, Motorcycle and Cycle Industries. accredited by COFRAC also recognized as a certification body by the International Automotive Task Force (IATF). UTAC is officially designated by the French authorities to the European Commission to carry out the approval tests of any vehicle and equipment under European directives. Japan, Taiwan and Australia have appointed UTAC to perform tests under their national DEMANDEIRI PLEIADES TECHNOLOGIES...
