Osram to launch LED-based au­to­mo­tive sig­nal lamps

Auto components India - - COVER STORY - ACI Bu­reau ACI

The Mu­nich-based Osram is launch­ing XLS (eXchangable LED Sig­nal), stan­dard­ised LED light sources for sig­nal light ap­pli­ca­tions in the au­to­mo­tive in­dus­try. By com­bin­ing stan­dard­ised light sources and LED tech­nol­ogy, the com­pany will fun­da­men­tally change the au­to­mo­tive sig­nal lamp sec­tor.

“For the first time, a uni­form plat­form with 4 dif­fer­ent light sources can cover all the im­por­tant sig­nal ap­pli­ca­tions in ve­hi­cles. This al­lows sim­ple re­place­ments, re­duces com­plex­ity and over­all costs for car man­u­fac­tur­ers and leads to faster de­vel­op­ment pro­cesses thanks to adapted stan­dards,” Hans-Joachim Schwabe, CEO Spe­cialty Light­ing, Osram, said. The LED-based sig­nal lamps are sched­uled to ap­pear on the roads by Oc­to­ber 2018.

Over the past few years, LED tech­nol­ogy has brought many ben­e­fits in terms of de­sign and has led to greater en­ergy ef­fi­ciency. There­fore, a be­wil­der­ing ar­ray of ve­hi­cle-spe­cific so­lu­tions has been cre­ated. To re­duce this com­plex­ity, Osram has de­vel­oped an in­no­va­tive stan­dard­ised LED light source for sig­nal light ap­pli­ca­tions. With the XLS prod­uct fam­ily Osram is launch­ing a sig­nal light port­fo­lio that of­fers all the in­no­va­tive ben­e­fits of LED tech­nol­ogy while of­fer­ing the proven ben­e­fits of tra­di­tional lamps such as stan­dard­i­s­a­tion and ex­change­abil­ity.

A sin­gle plat­form

The UN/ECE (R128) stan­dard­ised lamps will be avail­able in 4 types for dif­fer­ent sig­nal ap­pli­ca­tions in yel­low (LY5), white (LW5, L1) and red (LR5). The yel­low LY5 with 280 lu­men and a life of up to 4,000 hours is used for turn-in­di­ca­tors. LW5 is a white sig­nal lamp for re­vers­ing and DLR lights with 350 lu­men and a life of up to 5,000 hours.

The 2 other mem­bers of the XLS prod­uct fam­ily cur­rently in plan­ning are a red brake, rear and fog light (LR5), which pro­vides up to 4,000 hours of light with a lu­mi­nous flux of 120 lu­men, and a white high­pre­ci­sion fog light (L1) with up to 350 lu­men and a life of up to 5,000 hours. With pro­tec­tion against elec­tro­static dis­charge, po­lar­ity re­ver­sal and over­volt­ages the Osram XLS prod­ucts com­ply with all stan­dard re­quire­ments for mod­ern ve­hi­cle elec­tron­ics. Osram uses chip-on­board tech­nol­ogy for its XLS light sources. This en­ables the LED chips to be spaced very close to one an­other with com­mon op­tics.

The XLS prod­uct fam­ily de­liv­ers a wide range of ben­e­fits for con­sumers, head­light man­u­fac­tur­ers and car man­u­fac­tur­ers. A stan­dard­ised plat­form for LED sig­nal lamps re­duces the num­ber of in­di­vid­ual so­lu­tions for ve­hi­cle mod­els. In­te­grat­ing the heat sink and elec­tron­ics in the light source elim­i­nates the costs for their de­sign and ap­proval for each in­di­vid­ual so­lu­tion. All this con­sid­er­ably re­duces over­all costs for car man­u­fac­tur­ers across the var­i­ous ar­eas – such as the sup­ply chain and qual­ity con­trol. The re­use of de­sign mod­ules and the same plat­forms also cuts down on the time, ef­fort and costs of de­vel­op­ment. For car work­shops and car own­ers a stan­dard­ised so­lu­tion means the light sources can be di­rectly re­placed in the event of a fault, which in turn means lower re­pair costs and greater road safety. Long-term avail­abil­ity of the lamps will en­cour­age the es­tab­lish­ment of the XLS prod­uct fam­ily.

Se­ries pro­duc­tion of the lamps in the au­to­mo­tive plant in Her­brechtin­gen, Ger­many, guar­an­tees pre­mium qual­ity and is an im­por­tant mile­stone in the fur­ther de­vel­op­ment of stan­dard­ised au­to­mo­tive light sources. Cus­tomers of XLS prod­ucts ben­e­fit from the many years of ex­pe­ri­ence at this plant in man­u­fac­tur­ing car lamps.

The stan­dard­ised XLS prod­uct fam­ily en­ables de­sign cy­cles to be shorter and com­plex­ity to be re­duced, mak­ing it a pioneer for the wide­spread pen­e­tra­tion of LED tech­nol­ogy in high-vol­ume ve­hi­cle seg­ments. Osram’s launch of LY5 and LW5 in yel­low and white means that for the first-time users (Tier1/OEMs) can equip ve­hi­cles with stan­dard­ised ex­change­able LED sig­nal light sources in all sig­nal ap­pli­ca­tions.
