Safety-crit­i­cal light­ings light up ve­hi­cle aes­thet­ics

Auto components India - - COVER STORY - ACI Bu­reau

The au­to­mo­tive in­dus­try is grow­ing in dif­fer­ent di­rec­tions. Light­ing is a vi­tal com­po­nent in au­to­mo­tive ve­hi­cles, play­ing an im­por­tant role in au­to­mo­tive safety. The ve­hi­cle con­sists of dif­fer­ent lights to in­crease vis­i­bil­ity in dark­ness and bad weather along with the in­crease in com­plic­ity. For light­ing, which is safety crit­i­cal and an es­sen­tial in­gre­di­ent of ve­hi­cle aes­thet­ics, en­hanc­ing the aes­thetic looks to both in­te­rior and ex­te­rior parts.

The light­ing sys­tem com­prises light­ing and sig­nalling de­vices, which are placed at dif­fer­ent lo­ca­tions such as front, rear, side, and in­te­ri­ors. Light­ing pro­vides il­lu­mi­na­tion for the driver and helps other ve­hi­cle driv­ers and pedes­tri­ans on the road to de­tect the ve­hi­cle’s po­si­tion, di­rec­tion of move­ment, and size. The con­sumers are look­ing be­yond in­can­des­cent lights. Pref­er­ence is for high in­ten­sity dis­charge (HID) head­lights and other 12V LED light­ing so­lu­tions. Even more op­tions and mod­i­fi­ca­tions are avail­able now. There are amaz­ing new tech­nolo­gies. But many of them are not gen­uine im­prove­ments or even street-le­gal.

Au­to­mo­tive light­ing had been chang­ing along with the ve­hi­cles un­til it reached the halo­gens through in­can­des­cent bulbs. With their in­creased light out­put halo­gens are the most com­mon light source for head­lights even to­day. They are giv­ing way to HID (high in­ten­sity dis­charge) bulbs and LED (light emit­ting diode) lights and OELDs (or­ganic light emit­ting diodes).

The ma­jor play­ers op­er­at­ing in the mar­ket of global au­to­mo­tive light­ing are Mag­neti Marelli (Italy), Philips Light­ing NV (Nether­lands), Ichikoh In­dus­tries Ltd (Ja­pan), Hella KGaA Hueck & Co (Ger­many), Koito Man­u­fac­tur­ing Co Ltd (Ja­pan), ZKW Licht­sys­teme GmbH (Wiesel­burg), Peter­son Man­u­fac­tur­ing com­pany (U.S.), OSRAM GmbH (Ger­many), Stan­ley Elec­tric Co. Ltd (Ja­pan), and Gen­eral Elec­tric (USA).

In­dia’s au­to­mo­tive light­ing mar­ket is ex­pected to garner $3.1 bil­lion by 2022, reg­is­ter­ing a CAGR of 5.6%, says a re­port pub­lished by Al­lied Mar­ket Re­search. The In­dian au­to­mo­tive light­ing mar­ket has wit­nessed sig­nif­i­cant growth on ac­count of in­creased au­to­mo­tive sales and eco­nomic growth. In ad­di­tion, it is driven by in­creas­ing pop­u­la­tion and con­cerns about ve­hi­cle safety trig­gered by gov­ern­ment reg­u­la­tions.

Im­pact­ing fac­tors

Grow­ing em­pha­sis on road safety: Ris­ing num­ber of road ac­ci­dents dur­ing bad weather con­di­tions and night is the prime con­cern among ve­hi­cle driv­ers. This has risen the de­mand for re­li­able and bright­ened au­to­mo­tive lights. There­fore, the grow­ing em­pha­sis over en­hanced road safety through high-per­for­mance au­to­mo­tive lights has cre­ated the need to de­velop ad­vanced lights pro­vid­ing bet­ter il­lu­mi­na­tion in the dark­ness.

New reg­u­la­tions: The In­dian

gov­ern­ment has for­mu­lated var­i­ous reg­u­la­tions re­gard­ing suf­fi­cient in­stal­la­tion of light­ing equip­ment in pas­sen­ger ve­hi­cles. Few reg­u­la­tions are still in the process of be­ing laid down to im­prove the safety of ve­hi­cle in bad weather con­di­tions. The reg­u­la­tions re­gard­ing en­er­gy­ef­fi­cient ve­hi­cles sup­port the in­stal­la­tion of LED lights in ve­hi­cles. Thus, such reg­u­la­tions are ex­pected to fuel the growth of the au­to­mo­tive light­ing mar­ket.

Ris­ing ve­hi­cle sales: Au­to­mo­bile sales has wit­nessed no­table growth rate in In­dia. The re­vival of econ­omy has par­tic­u­larly sup­ported the growth in the re­cent past. This grow­ing trend is ex­pected to con­tinue dur­ing the fore­cast pe­riod with size­able de­mand of pas­sen­ger ve­hi­cle and two-wheel­ers. Au­to­mo­tive light­ing in­dus­try, which de­pends on the state of au­to­mo­tive in­dus­try for its growth, is ex­pected to cer­tainly ben­e­fit from this on­go­ing ris­ing ve­hi­cle sale.

LEDs to the fore

Nu­mer­ous tech­no­log­i­cal ad­vance­ments were ob­served in the com­mer­cial au­to­mo­tive light­ing down the years. Cur­rently, the seg­ment for LED light­ing tech­nol­ogy is gain­ing wide­spread pop­u­lar­ity world­wide. Ac­cord­ing to a re­cent re­port pub­lished by Al­lied Mar­ket Re­search, ti­tled, `Global LED mar­ket by type and ap­pli­ca­tion: Global op­por­tu­nity anal­y­sis and in­dus­try fore­cast, 2018-24’, the global LED mar­ket was val­ued at $33.10 bil­lion in 2017, and is pro­jected to reach $96.71 Bil­lion by 2024, reg­is­ter­ing a CAGR of 15.9% from 2018 to 2024.

LEDs are used in va­ri­ety of ap­pli­ca­tions. A few years ago, ap­pli­ca­tion of LED was lim­ited to cer­tain spe­cific light­ing needs and had not en­tered the main­stream gen­eral light­ing ap­pli­ca­tions. En­trance of LED in ap­pli­ca­tions such as gen­eral light­ings have given a strong thrust to the mar­ket. LED is ex­pected to take over the con­ven­tional CFL and CCFL light­ing mar­ket due to ad­vanced fea­tures. More­over, it is a cost­ef­fec­tive so­lu­tion for all light­ing as well as other ap­pli­ca­tion pur­poses such as back­light­ing in large screen dis­plays, au­to­mo­tive light­ing and many oth­ers.

At pre­sent, Asia Pa­cific dom­i­nates the mar­ket, fol­lowed by Europe. In 2017, the U.S. is ex­pected to re­main dom­i­nant in the North Amer­ica mar­ket, while China is pro­jected to lead the over­all mar­ket in Asia Pa­cific.

In­crease in gov­ern­ment fo­cus on en­ergy sav­ing so­lu­tions, in­crease in util­ity re­bates, and Grow­ing dis­play and large screen back­light­ing mar­ket are the fac­tors that drive the mar­ket. In ad­di­tion, growth of smart light­ing and high ef­fi­cacy LED boost the growth of the LED mar­ket. How­ever, high ini­tial cost re­stricts the growth of the mar­ket.

For au­to­mo­tive, LEDs are also ex­cel­lent for ex­tremely bright off-road bar lights. Their high ef­fi­ciency al­lows them to con­sume sig­nif­i­cantly less power to pro­duce the same amount of light as other sources or con­sume the same amount of power and pro­duce huge amounts of light. A 100W in­can­des­cent flood light pro­duc­ing 1500lm could be re­placed with a 13W LED bulb, or an LED bulb could con­sume 100W to pro­vide over 10,000lm. Even though 100W is a rea­son­able amount of power

to draw from a car bat­tery, the bat­tery volt­age is only 12V. This means the PCB sup­port­ing the LEDs in a bar light needs to be able to han­dle mov­ing over 8A of cur­rent with­out in­cur­ring volt­age drops that would cause LEDs at the ex­trem­i­ties to dim.

The Fu­ture

Sev­eral stud­ies as­cer­tain that the fu­ture of au­to­mo­tive light­ing is bright, but the im­me­di­ate fu­ture is not quite as “smart” as that of other ver­ti­cals be­cause the reg­u­la­tions are sim­ply not pre­pared to han­dle the new­est tech­nolo­gies. Adap­tive head­lights are al­ready ris­ing in pop­u­lar­ity in Europe. Reg­u­la­tory agen­cies in In­dia could bring this to In­dia along with BSVI and the new road safety reg­u­la­tions. Adop­tion of LEDs are set to rise as they are be­com­ing more af­ford­able and get de­signed into ve­hi­cles from the orig­i­nal man­u­fac­turer, rather than only be­ing avail­able as an af­ter­mar­ket mod­i­fi­ca­tion.

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

“For the first time, a uni­form plat­form with four dif­fer­ent light sources so can cover all the im­por­tant sig­nal si ap­pli­ca­tions in ve­hi­cles. This T al­lows sim­ple re­place­ments, re­duces re com­plex­ity and over­all costs co for car man­u­fac­tur­ers and leads le to faster de­vel­op­ment pro­cesses p thanks to adapted stan­dards”, st Hans-Joachim Schwabe, Sc CEO Spe­cialty Light­ing, Osram, O said. The LED-based sig­nal lamps la are sched­uled to ap­pear on the th roads by Oc­to­ber 2018. Fiem In­dus­tries Ltd, a lead­ing man­u­fac­turer of au­to­mo­tive light­ing, sig­nalling equip­ment and rear-view mir­rors, is pre­sent in all types of au­to­mo­tive light­ings. Through joint ven­tures the com­pany is di­ver­si­fy­ing its prod­uct port­fo­lio. As the in­dus­try is look­ing for in­no­va­tive, per­for­mance­ori­ented lamps, Fiem con­cen­trates on global bench­mark­ing of prod­ucts to get the high­est level of tech­nol­ogy and fea­tures very cost-ef­fec­tively. The com­pany sup­plies LED lamps to its two and 4-wheeler OEM cus­tomers in In­dia. It is also de­vel­op­ing many new gen­er­a­tion lamps for some of the forth­com­ing mod­els of renowned OEMs.

With a lot of safety norms com­ing in, In­dia Ja­pan Light­ing (IJL) plans to make all lamps LED in the In­dian mar­ket. IJL also plans to bring in the new Adop­tive Driv­ing Beam (ADB). This will be the com­pany’s drive for the In­dian mar­ket. ADB changes high beam to low beam au­to­mat­i­cally when it senses the traf­fic in the op­po­site di­rec­tion. It recog­nises the po­si­tion of the other rider. In In­dia, driv­ing al­ways is with high beam. With the cam­era and sen­sors, ADB will help the change. It is ex­pected to be launched by 2022. For its ef­fec­tive ap­pli­ca­tion cus­tomers will have to up­grade the ve­hi­cle with cam­era and sen­sors. ADB will be thrice costlier than LEDs.

Phoenix Lamps Di­vi­sion, a unit of Supra­jit Engi­neer­ing Ltd (formerly Phoenix Lamps Ltd), which man­u­fac­tures and sup­plies halo­gen lamps for the au­to­mo­tive sec­tor, is in­tro­duc­ing new H4 and H7 halo­gen bulbs with ex­tra life. Phoenix be­lieves that halo­gens will re­main for long in the af­ter­mar­ket, even if OEMs go for LEDs in a big way.
