Lighting technology<\/h2><\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>Light for our purposes is defined by light intensity and colour point. The illumination level indicates the luminance on a surface. It has a distance-based effect on the light intensity. A specific lateral emission is also frequently defined, i.e. there are specifications on the light intensity outside the centrepoint. The colour point can be stated with reference to the standardised CIE colour system (x,y coordinates) or as spectral light distribution. In the specifications, we can normally refer to the relevant guidelines by the UIC, ECE or TSI.<\/p>\n
<\/p>\n
In our in-house lighting laboratory, our specialists can measure the following parameters using calibrated equipment:
\n\u00b7 Light intensity and distribution in cd in distance up to 10m
\n\u00b7 Illumination level in lx
\n\u00b7 Colour points
\n\u00b7 Spectral light distribution (k values)
\n\u00b7 Measurements in the system, i.e. with on-board panes and structural environments<\/p>\n
<\/p>\n
We carry out measurements for development support, approval preparation and quality assurance, in particular. We work with independent specialist institutions for conformity measurements, e.g. for approval. We are also happy to show our customers the lights on the test bench.<\/p>\n
<\/p>\n
Almost all new lights are manufactured with LED technology. The following decision-making criteria frequently apply:<\/p>\n
<\/p>\n
LED
\n\u00b7 Life span approx. 30,000 hours and more, defined as life span in the standard
\n\u00b7 All light functions, marker and tail lights and headlights are now possible. The focal point here is often on marker \/ tail light functions with lower light intensities.
\n\u00b7 New design options, light contributes to the appearance and recognition of the vehicle
\n\u00b7 Light intensities are increasing \u2013 Standardised top values are reliably achieved
\n\u00b7 Thermal management of high-beam headlights is critical
\n\u00b7 Colour management in order to avoid glare for other participants due to cold white light
\n\u00b7 \u201cFit and Forget\u201d \u2013 Accessibility as a design requirement is becoming less important<\/p>\n
<\/p>\n
Halogen and light bulb systems
\n\u00b7 Light is produced using a spiral-wound filament, red light through the filter, e.g. glass cylinder
\n\u00b7 High distribution in stock \/ replacement parts
\n\u00b7 Life span of modern H1 lamps > 1,200 hours (longlife)
\n\u00b7 Cost-effective, great diversity of light intensities and designs<\/p>\n
<\/p>\n
Xenon \/ HID
\n\u00b7 B3 life span approx. 1800 hours \/ TC approx. 3,000 hours
\n\u00b7 Brightest light based on space requirement, > 400,000 cd in a 145mmD headlight is possible
\n\u00b7 Starter unit required
\n\u00b7 Low heat development (through 35W)
\n\u00b7 Perfect for small installation spaces and strong light
\n\u00b7 Higher lamp costs<\/p>\n
<\/p>\n
Fluorescent bulbs
\n\u00b7 Interior lights
\n\u00b7 Life spans > 10,000 hours now possible
\n\u00b7 Higher colour rendering index increases well-being<\/p>\n<\/div>
