SAE Update - December 2023 - 45

STANDARDS & COMMITTEES
Recommended Practice, it laid out the
critical parameters and framework essential
for this lighting technology. SAE J3069 had
a further update, fine-tuning the earlier
release; today, work continues with an
upcoming information report that will aid
the industry in testing systems and to help
design future systems.
All this advanced lighting technology
requires testing at many different levels. The
SAE LSG has developed new testing methods
and procedures in existing test documents,
developing new documents and adding
procedures, recommendations, or guidelines
to put in our functional J-documents. With
light sources now able to operate many times
longer than before, the lighting assemblies
must also have increased lifetime capability.
To address this critical need, the group
developed SAE J3086, which answers the call
for increased robustness of materials and
coatings used in headlamps. This was an
outstanding effort combining forces from the
materials, testing, and lamp manufacturer
areas to develop a recommended test
procedure for the industry.
A few years ago, the SAE LSG brought
the motorcycle lighting activity into the
group. A very-much-needed update to SAE
J584 was accomplished, bringing this
headlamp document to a level that the
industry can better employ. Further work
will continue to better harmonize the
document with its global counterparts as
we strive to make our documents
compatible worldwide.
UPDATE
Many additional lighting types are quickly
becoming more commonplace on today's
vehicles. Lighting welcomes you to your
vehicle and lights the pathway as you exit.
Soon, additional signaling lights, directional
lights, and warning lights will project to the
surrounding scene to aid the driver and
forewarn pedestrians/bicyclists of vehicle
presence and intended actions. Several new
J-documents are currently in development
to address these areas. This is another
instance of global collaboration to come to
a harmonization level of new lighting
technology. The SAE LSG has a strong
presence in the global lighting community
with active participation in many groups
and organizations.
I am very proud of all these group
accomplishments. It has been a very
gratifying-yet sometimes hectic-
experience, and I very much appreciate
SAE International providing me the
opportunity to lead this group, all the while
continuing to learn and engage with
industry colleagues.
A big salute to all the SAE LSG volunteers
over the years-superb job! n
