SMD-LEDs: mbiri ndi waukulu makhalidwe

Zotsatira LED munthu zinali kuonekera kwa nthawi yoyamba zaka 90 zapitazo. Zimenezi zinachitika mu Russia mu 1923, pamene Oleg Losev mu Nizhny Novgorod anali woyamba anati ndi luminescence wa pakachitsulo carbide zasayansi amagetsi. Nkhani Scientific pa nkhani ino anasindikizidwa mu 30s Mu zaka zapitazo, ndipo mamangidwe choyamba anaonekera okha 70s lapansi. mu Leningrad, Zelenograd ndi Kaluga. Yogwira chitukuko njira kugwirizana ndi apolisi magalimoto malangizo kwa kupanga 1,000 maloboti kuti patha zaka 850th likulu, imene m'malo nyali incandescent ntchito yowala LEDs wobiriwira.

Inatsogolera ndi michenga yopangira zida zamagetsi Chip zaikidwa ndi gawo lapansi kwa zotayidwa kapena mkuwa ndi cholinga dongosolo kuwala ndi malo. Anatsogolera SMD (padziko montage mfundo) kwa mitundu ina amakhala mu magawo m'menemo ali wokwera mwachindunji padziko. Crystal nyumba kwa njira imeneyi mwakula ndi epitaxy organometallic. Pa ndondomeko iyi, mkati mwa tsiku lina, mukhoza kukula kapangidwe anakhumba (tchipisi) kuti munthu pazipita magawo 12.

Kenako, timibulu analandira asonyezedwa mwa luso mkulu iwo amasonkhana thupi anapanga zotuluka chagwiritsidwa, zinthu zina Napempha anakonza kutentha moganizira. Chinthu Ichi ndi mtengo, kotero SMD LEDs ndi okwera mtengo kusiyana ndi mababu wamba. Akukhulupirira kuti ndalama pa lumen kwaiye LED nthawi 100 kuposa unit chomwecho opangidwa ndi nyali halogen.

The makhalidwe abwino a kachitidwe monga wochepa, mkulu mtundu chiyero, pakalibe infuraredi ndi ultraviolet poizoniyu okwanira mphamvu, durability ndi chitetezo. Today liruyuschey dziko lonse, kumene zokolola SMD-LEDs, ndi Japan.

Pamene akugwira ntchito zinthu izi zambiri tikambirana makhalidwe zotsatirazi:

- kuwala, zimenezi woyera (ofunda kapena ozizira), buluu, wobiriwira, chikasu kapena wofiira. White kuwala SMD-LEDs analandira m'njira zambiri, kuphatikizapo njira RGB, pamene mitundu yosiyanasiyana ali osokonezeka ndi mandala kapena kachitidwe kena kuwala;

- m'dziko la magwero a Chip (amangoona, Taiwan);

- wowala kamwazi (lumens);

- chofunika voteji;

- chiwerengero cha makhiristo (tchipisi);

- zofunika mphamvu panopa;

- ngodya zounikira (45 140 madigiri);

- kukhalapo kapena kusapezeka kwa gawo lapansi, chomwe nthawi zambiri ndi zina mtengo.

SMD-LEDs ankagwiritsa ntchito kuunikira m'madera osiyanasiyana. okonza awo kukonda khalidwe mkulu wa kuunika ndi chitetezo magetsi, wogwila ntchito zofunikira pagulu - kudya otsika mphamvu ndi mkulu vandal kukana. Yekha kugwiritsa ntchito njira zamakono izi lero pamaso pa malo aakulu, kotero iwo si ntchito pa ulimi. LED Mzere masiku ano m'mabanja, malo omwera ndi maudindo, kuphatikizapo malo ndi chilengedwe chinyezi, chifukwa pali mitundu ina ya diodes samuopa madzi.

The moyo utumiki mwa zipangizozi ndi lalikulu (50 000 maola zitsanzo mkulu-mapeto), kotero ife tikhoza kunena, SMD-LEDs - ndi chida kwambiri kuunikira m'tsogolo.
