Mababu a LED owunikira magetsi

Pali mitundu inayi yayikulu ya mababu omwe amagwiritsidwa ntchito poyatsira magalimoto: mababu wamba a incandescent, xenon (kutulutsa kwa gasi), halogen ndi mababu a LED. Onse ali ndi zabwino zawo ndi zovuta zawo. Zomwe zimagwiritsidwa ntchito kwambiri zimakhalabe halogen, koma nyali za LED mu nyali zikutchuka kwambiri. Zinthu zingapo zimathandizira izi, zomwe tikambirana mwatsatanetsatane m'nkhaniyi.

Kodi nyali za LED mu nyali zamagalimoto ndi ziti?

Mtundu wa nyali umatengera kugwiritsa ntchito ma LED. M'malo mwake, awa ndi ma semiconductors, omwe, podutsa mphamvu yamagetsi, amapanga kuwala kowala. Ndi mphamvu zamakono za 1 W, amatha kutulutsa kuwala kwa 70-100, ndipo pagulu la zidutswa 20 mpaka 40 mtengo uwu ndiwokwera kwambiri. Chifukwa chake, nyali zama LED zamagalimoto zimatha kupanga kuwala mpaka 2000 lumens ndikugwira ntchito kuyambira 30 mpaka maola 000 ndikuchepa pang'ono kwa kuwala. Kupezeka kwa ulusi wa incandescent kumapangitsa nyali za LED kugonjetsedwa ndi kuwonongeka kwamakina.

Makhalidwe apangidwe la nyali za LED ndi momwe amagwirira ntchito

Chosavuta ndichoti ma LED amatenthetsa panthawi yogwira ntchito. Vutoli limathetsedwa ndimativi otentha. Kutentha kumachotsedwa mwachilengedwe kapena ndi fan. Mbale zamkuwa zopangidwa ndi mchira nthawi zambiri zimagwiritsidwa ntchito potulutsa kutentha, monga nyali za Phillips.

Makina, magetsi a magetsi a LED amakhala ndi zinthu zazikuluzikulu izi:

• Kutentha kuchititsa chubu yamkuwa ndi ma LED.
• M'munsi mwa nyali (nthawi zambiri H4 pamutu).
• Aluminiyamu yokhala ndi heatsink, kapena kabokosi kogwiritsa ntchito heatsink yamkuwa.
• Woyendetsa nyali ya LED.

Dalaivala ndi makina ozungulira omwe ali mkati kapena chinthu china chomwe chimafunikira kuti magetsi azigwira bwino.

Mitundu ndi chodetsa cha nyali za LED ndi mphamvu ndi kutuluka kowala

Mphamvu yamagetsi ya nyali imawonetsedwa pamikhalidwe yagalimoto. Malinga ndi mphamvuyo, mafiyuzi ndi magawo amtambo amasankhidwa. Kuti muwonetsetse kuwunika kokwanira kwa mseu, kutuluka kowala kuyenera kukhala kokwanira komanso koyenera mtundu wa malonda.

Pansipa pali tebulo la mitundu yosiyanasiyana ya halogen ndi madzi ofanana a LED poyerekeza. Pa nyali zazikulu komanso zotsika mtengo, kapu yolemba ndi chilembo "H" imagwiritsidwa ntchito. Maziko ofala kwambiri ndi H4 ndi H7. Mwachitsanzo, nyali yamadzi oundana a H4 imakhala ndi gulu lina lokhala ndi ma diode okwera kwambiri komanso gulu lina lokhala ndi zotsika.

Kuyika koyambira / plinth	Halogen nyali mphamvu (W)	Mphamvu yamagetsi ya LED (W)	Wowala kamwazi (lm)
H1 (magetsi a utsi, mtanda waukulu)	55	5,5	1550
H3 (magetsi a utsi)	55	5,5	1450
Н4 (yophatikizidwa yayitali / yayifupi)	60	6	1000 pafupi   1650 wautali
H7 (kuwala kwamutu, magetsi amoto)	55	5,5	1500
H8 (kuwala kwamutu, magetsi amoto)	35	3,5	800

Monga mukuwonera, nyali za LED zimawononga mphamvu zochepa, koma zimakhala ndi zowunikira zabwino kwambiri. Ichi ndi kuphatikiza kwina. Zomwe zili patebulopo zimakhala ndi tanthauzo. Zogulitsa kuchokera kwa opanga osiyanasiyana zimatha kusiyanasiyana pakugwiritsa ntchito mphamvu ndi mphamvu.

Ma LED amalola kuwongolera kwakanthawi pakuwunikira. Monga tanenera, izi zimatheka pogwiritsa ntchito ma LED awiri kapena amodzi mu nyali. Gome ili m'munsi likuwonetsa mitundu iwiri yamatayala ndi mitundu iwiri ya nyali zotsogozedwa.

mtundu	Kuyika koyambira / plinth
Mtengo umodzi	H1, H3, H7, H8 / H9 / H11, 9005, 9006, 880/881
Matabwa awiri	H4, H13, 9004, 9007

Mitundu ya ma LED m'munda

• Mkulu mtengo... Pamtengo wokwera, nyali za LED ndizabwino ndipo zimawunikira bwino. Plinths H1, HB3, H11 ndi H9 amagwiritsidwa ntchito. Koma dalaivala ayenera kukumbukira nthawi zonse kuti azikhala ndi nyali, makamaka ndi mphamvu yayikulu. Pali kuthekera kokweza magalimoto omwe akubwera ngakhale atakhala otsika mtengo.
• Mtengo wotsika... Kuunikira kwadothi lotsika kumapereka kuwala kokhazikika komanso kolimba poyerekeza ndi anzawo a halogen. Zofananira plinths H1, H8, H7, H11, HB4.
• Magetsi oyimitsira magalimoto ndikusintha ma sign... Ndi ma LED, adzawonekera kwambiri mumdima, ndipo kugwiritsa ntchito mphamvu kumachepetsedwa.
• Magetsi a utsi. Yoyendetsedwa mu PTF imapereka kuwala koyera komanso imathandizira magetsi.
• Mkati mwa galimoto... Payekha, ma diode amatha kutulutsa mtundu wonse wamitundu. Kuyatsa kwamphamvu kwa kanyumba kungasinthidwe pogwiritsa ntchito mphamvu yakutali pempho la mwiniwake.

Monga mukuwonera, mitundu yosiyanasiyana yama diode mgalimoto ndiyotakata. Chinthu chachikulu ndikusintha nyali pamiyala yapadera. Komanso, nyali za LED sizingafanane ndi nyali yamutu, chifukwa nthawi zonse imakhala yayitali. Redieta kapena mchira mwina sizingakwane, ndipo khola silingatseke.

Momwe mungasinthire nyali wamba ndi diode

Sikovuta m'malo mwa "halogen" wamba ndi ma LED, chinthu chachikulu ndikusankha maziko oyenera, sankhani mtundu woyenera wa kutentha, komwe mtundu wa kuwalako udalira. Pansipa pali tebulo:

Mthunzi wowala	Nyali mtundu kutentha (K)
Kutentha kwakuda	Kutulutsa: 2700K-2900K
Kutentha koyera	3000K
Woyera woyera	4000K
Oyera ozizira (kusintha kwa buluu)	6000K

Akatswiri amalangiza kuyambitsanso ndi magetsi am'mbali, kuyatsa kwamkati, thunthu, ndi zina zambiri. Kenako fanizani ma LED mumutu wamtundu ndi kapu yoyenera. Nthawi zambiri imakhala H4 yokhala ndi matabwa awiri apafupi komanso akutali.

Ma LED amachepetsa kwambiri katundu pa jenereta. Ngati galimoto ili ndi njira yodziyesera yokha, ndiye kuti kugwiritsa ntchito mphamvu zochepa kumatha kuwonetsa chenjezo lokhudza mababu olakwika. Vutoli limathetsedwa ndikusintha makompyuta.

Kodi ndizotheka kukhazikitsa mababu a LED mu nyali zamagetsi

Sizophweka kutenga ndikukhazikitsa mababu wamba ndi ma diode. Choyamba muyenera kuwonetsetsa kuti nyali yanu yam'manja ikukwaniritsa zofunikira ndi chitetezo. Mwachitsanzo, zolemba za HCR ndi HR zimakupatsani mwayi wosintha nyali za halogen ndi nyali za diode zamtundu wofananira kuchokera ku fakitaleyo. Uku sikungakhale kulakwa. Ndikofunikanso kugwiritsa ntchito zoyera zokha pamutu. Kukhazikitsa makina ochapira ndichosankha, ndipo simungasinthe galimoto palokha mukayika.

Zowonjezera zowonjezera zowonjezera

Palinso zofunikira zina pakusintha mtundu wa kuyatsa:

• kuunika sikuyenera kuwunikira mtsinje ukubwera;
• nyali yoyendera iyenera "kudutsa" mtunda wokwanira kuti woyendetsa azitha kuzindikira zoopsa zomwe zingachitike panjira;
• dalaivala ayenera kusiyanitsa pakati pa utoto pamoto usiku, motero kuyatsa koyera ndikulimbikitsidwa;
• ngati chowunikira nyali sichilola kuyika kwa kuyatsa kwa diode, ndiye kuti kuyika sikuletsedwa. Izi ndizolangidwa chifukwa chalandidwa ufulu kuyambira miyezi 6 mpaka chaka. Mtengo umasinthanso ndikuwala mbali zosiyanasiyana, ndikuchititsa khungu madalaivala ena.

Ndizotheka kukhazikitsa ma LED, koma pokhapokha potsatira luso ndi malamulo. Ili ndi yankho labwino kwambiri pakukonza kuyatsa. Malinga ndi akatswiri, popita nthawi, nyali zamtunduwu zimalowa m'malo mwa nthawi zonse.

Mafunso ndi Mayankho:

Kodi nyali zakutsogolo za diode ndi ziti? Zida zonse zomwe zimagwiritsidwa ntchito mu nyali za LED zimalembedwa ndi chidule cha HCR. Ma lens ndi zowunikira za nyali za LED zimayikidwa chizindikiro cha LED.

Kodi mungadziwe bwanji chizindikiro cha nyali? C / R - mtengo wotsika / wapamwamba, H - halogen, HCR - babu wa halogen wokhala ndi mtengo wotsika komanso wapamwamba, DC - xenon low mtengo, DCR - xenon wokhala ndi mtengo wapamwamba komanso wotsika.

Kodi ndi mababu a LED ati omwe amaloledwa mu nyali? Nyali za LED zimatengedwa ndi lamulo ngati halogen, kotero nyali za LED zikhoza kuikidwa m'malo mwazomwe zimagwiritsidwa ntchito (ma halogens amaloledwa), koma ngati nyali yapamutu imalembedwa HR, HC kapena HRC.
