DALI nyob ib puag ncig ntev npaum li cas?

Keeb kwm ntawm DALI yog fascinating. Thawj lub tswv yim rau qhov no yog los ntawm European ballast makers. Thawj lub tuam txhab ballast tau ua haujlwm nrog peb lwm tus los tawm tswv yim kom tau txais International Electrotechnical Commission (IEC) los ua tus qauv rau yuav ua li cas ballasts sib tham. Nyob rau hauv nruab nrab ntawm tag nrho cov, nyob rau hauv lub lig 1990s, lub tebchaws United States kuj tau koom tes.

Pekka Hakkarainen, tus thawj coj ntawm kev siv thev naus laus zis thiab kev tsim kho kev lag luam ntawm Lutron Electronics hauv Coopersburg, PA, thiab tus thawj coj ntawm Pawg Tswj Xyuas Teeb pom kev zoo ntawm National Electrical Manufacturers Association hauv Rosslyn, VA, hais tias tus qauv yog ib feem ntawm IEC tus qauv rau fluorescent ballasts thiab yog ib qho ntawm cov txheej txheem txuas ntxiv (NEMA). Cov txheej txheem rau kev sib txuas lus nrog ballast uas feem ntau tau txais yog muab.

Thaum xyoo 1990s, thawj DALI LED tsav tsheb thiab ballasts tawm hauv Tebchaws Meskas. Los ntawm 2002, DALI tau dhau los ua tus qauv thoob ntiaj teb.
