Tepi LED: mphamvu, gulu, mitundu

Masiku ano, anawatsogolera Mzere Kuwala ntchito pounikira zosiyanasiyana zinthu, mkati ndi kunja malo a. Choncho, wotchuka. Koma kuti iwo kuti athe kugwira bwino ntchito zake, izo chofunika kusankha chipangizo ndi yaikulu kwambiri.

Akukhulupirira kuti mwa makhalidwe onse amene ali tepi anatsogozedwa, mphamvu ndi imodzi mwa magawo chachikulu. Iwo ndi zina zingapo chimatanthauza kuchuluka kwa fixture a. Choncho, posankha mankhwala anapereka kudziwa momwe magawo ayenera kulabadira mu malo oyamba.

makhalidwe General

Tepi LED zomwe mphamvu ayenera anasankha mwadala kwambiri, ali ndi mamangidwe wapadera. Ndi gulu kusintha pa zimene ankasindikiza ojambula kutero. Pa mfundo imeneyi, wogawana spaced diodes. Iwo ndi kuwala gwero la mankhwala.

The makulidwe filimu imeneyi si upambana 2-3 mm. m'lifupi ndi 8 kapena 10 mm. Zoletsa panopa likuyenderera mu diodes ndi, resistors ali wokwera pa tepi. Kutchuka kwa fixture izi chifukwa durability ake ndi dzuwa. Pafupifupi zipangizo ntchito anapereka kwa zikwi 50 100. Maola. Komabe, iwo kugula kuchuluka kochepa mphamvu.

Malinga ndi mphamvu tepi, komanso chiwerengero cha makhalidwe ena angagwiritsidwe ntchito mizere chiwalitsiro cha pamakoma, njira, zinthu za kamangidwe malo, komanso chilengedwe cha malonda. M'nyumba tepi ndi mtsikana polenga zosiyanasiyana zotsatira za kamangidwe mkati. Osiyanasiyana ntchito mankhwala amenewa ndi mkulu.

mitundu ya diodes

Choyamba, tiyenera kunena kuti pali mitundu iwiri ya magulu lero. chizindikiro awo monga RGB ndi SMD-chipangizo. Mtundu choyamba mwiniwake ndi mphamvu kulenga zosiyanasiyana mithunzi ya kuyatsa. Wake aliyense mchitidwe tichipeza diodes atatu. Choncho dzina la chipangizo. LEDs kuwala wofiira, wobiriwira, ndipo buluu mtundu (Red, Green, Blue - RGB).

Pakuti tepi chofunika kugula wapadera mphamvu ya kutali, wotchedwa Mtsogoleri. Mphamvu mowa LED Mzere umakhudza kusankha unit kulamulira. Iye zidzalamulira osati mtundu panamveka ndi chipangizo, komanso kuwala kwake, mwamphamvu.

The zosinthika chachiwiri chipangizo ndi tepi SMD - zinthu mopupuluma atakwera Chipangizo, kutanthauza "pamwamba wokwera chipangizo". Diodes mankhwala a mtundu womwewo. Iwo anabwera zoyera, buluu, wobiriwira, ofiira kapena wachikasu. Izi ndi chipangizo mtengo.

Kukula kwa LEDs kwa

Mphamvu LED tepi zimadalira kukula ndipo chiwerengero cha zinthu payekha. Iwo amakulolani kulenga kufunika mwamphamvu kuwala. Sitepe yoyamba ndi kuganizira kukula kwa diodes lapansi. Kulemba katundu zimatithandiza kumvetsa zimene mtundu wa chounikira ukufanizidwa mu kugulitsa.

Poyamba, chizindikiro amasonyeza mtundu mankhwala (RGB kapena SMD). Komanso chodetsa lili manambala 4. Ichi ndi kukula kwa diodes lapansi. Mwachitsanzo, kwalembedwa mu SMD3528 chodetsa, kutanthauza kuti kuyatsa zanyengo ndi m'litali ndi m'lifupi 3.5 × 2.8 mm.

Palinso diodes zikuluzikulu - 5050 kapena 5630. Kuwala SMD3528 5 lumens. Ndi zina chowala tepi muyeso. Mphamvu LED matepi 5050 ndi 5630 padzakhala. Wowala kamwazi panamveka ku anati diode, motero, adzakhala wofanana 15 ndi 18 lumens. Chifukwa cha makhalidwe amenewa akhoza m'malo LED Mzere kuwala kuyatsa wamba mphamvu yopulumutsa getsi.

Number pa diodes tepi

Chinthu china chofunika kudziwa LED Mzere mphamvu pa mita, ndi chiwerengero cha diodes. pafupipafupi awo ndi osiyana mu zipangizo zosiyanasiyana. The mankhwala muyezo amatuluka ndi chiwerengero cha zinthu 1 mamita 60 ma PC.

Kusintha kuwala ndi mphamvu ya tepi kumawonjezera chiwerengero cha diodes. Kwa tepi SMD3528 achuluke ndende ya zinthu kuyatsa 120 ndipo ngakhale ma PC 240. 1 m. Komabe, ambiri diodes ndi zosavomerezeka kwa matepi ndi diodes zikuluzikulu. Choncho SMD5050 ndi SMD5630 ndende ya zinthu izi ndi 30, 60 kapena 120 mayunitsi. mamita 1.

Iwo ayenera kukumbukira kuti nthawi zina kuwala sikudalira ndende kapena kukula kwa diodes ndi mtundu cheza kapena kutentha kuwala. Iwo ranges kuchokera 3000 K kwa 7000 K. The chidwi kwambiri anaona tepi, amene luminescence uli mkati osiyanasiyana 5500-7000 K.

mphamvu

Mawerengedwe a mphamvu LED Mzere wapangidwa zochokera kukula ndipo chiwerengero cha zanyengo pa mita. Izi amayezedwa Watts. Pakuti SMD3528 tepi khalidwe luminescence diodes 60 mphamvu - 4.8 W, diodes 120 - 9,6 Watts, ndi diodes pa 240 - 16.8 Watts. makhalidwe amenewa tikhulupirira mwa opanga onse katundu anapereka.

Nthawi zambiri mu kugulitsa ndi SMD5050 tepi. Iwo anapereka mphamvu yeniyeni pa mita. Ngati tepi lili diode 30, chithunzi ndi 7.2 Watts. 60 diodes kupatsa mankhwala ndi mphamvu 14,4 Watt ndi 120 diodes - 28,8 Watts.

makhalidwe amenewa ayenera kuganizira posankha. Pa izi zimatengera mtundu wa magetsi. Ngati njira imeneyi si anasankha bwino, chipangizo sizigwira ntchito kwa nthawi yayitali. mphamvu yake kotunga adzakhala overheat kapena tepi sizigwira ntchito konse. Choncho, mphamvu mawerengedwe wapangidwa kuvomerezedwa.

mphamvu mawerengedwe

Kusankha bwino mphamvu okwanira ndi kubala kugwirizana apamwamba, muyenera kuphunzira mmene kuwerengera mphamvu LED Mzere. Ndi luso yosavuta. Choyamba kudziwa kuchuluka mphamvu zida Adzaperekedwa ku 1 m. Njira imeneyi wasonyeza pamwamba.

Ndiye, mtengo kupeza kuchulukitsa ndi chiwerengero cha mamita tepi. Mwachitsanzo, chipangizo, amene kutalika 5 m. Mphamvu Zake pa mita wa 4.6 Watts. Izi zikutanthauza kuti mphamvu ya tepi lonse kuchita masamu motere:

• 5 mamita × 4.6 W / mamita = 23 Watts.

Adaputala ntchito bwino, amafunika kotunga mphamvu. Ngati tepi amakhala ndi 23 W, ulamuliro wagawo amatenga pang'ono wamphamvu kwambiri. Oyenera zida lakonzedwa 28 Watts. Mphamvu headroom ndi 20%.

Kusankha adaputala

Mphamvu LED Mzere amathandiza kusankha bwino ulamuliro unit. Masiku ano mu kugulitsa zipangizo diode ntchito pa panopa mwachindunji. Pa nthawi yomweyo ayenera kupereka voteji 12 kapena 24 V. Mu kugulitsa kumeneko, ntchito ndi kupereka chizindikiro 36 V ndi tepi, koma iwo n'zochepa kwambiri.

Sankhani adaputala lolondola ndi lophweka. Choyamba, muyenera kuphunzira kulemba chipangizo kuyatsa. Izo ziyenera kusonyeza voteji. Nthawi zambiri, ogula wapereka kwa tepi 12 V. The magetsi ayenera zizigwirizana chizindikiro ichi.

Sikuti kusankha adaputala azamagetsi ndi zambiri mphamvu. The apamwamba khalidwe ili, m'pamenenso tiyenera chipangizo. Akatswiri amanena kuti mphamvu ya 20% ya katundu adzakhala okwanira. Izi adzalola lamba ntchito bwino.

kalasi chitetezo

Mphamvu LED Mzere pa mita ndi khalidwe zofunika kwa mankhwala m'nkhaniyo. Koma iyi si njira yokha, ozikidwa pa kusankha. Malinga ntchito, pali magulu osiyanasiyana a chitetezo tepi.

Chifukwa malo ouma ndi zinthu zachilendo zachilengedwe, pakalibe fumbi kwambiri ntchito lotseguka zosiyanasiyana zipangizo. olemba awo lili index IP20.

Ngati chipinda wokongola yonyowa, mukhoza kugwiritsa ntchito chipangizo ndi chitetezo epoxy. Nkhanizi amateteza pamwamba pa lamba, koma osati LEDs. Choncho, njirayi siyabwino chifukwa unsembe panja. Chitetezo cha tepi amenewa ikusonyezedwa IP65.

Pakuti unsembe panja ntchito silikoni tepi olimba. Mmenemo ndiotetezedwa ku mavuto chilengedwe mbali zonse kamangidwe. IP68 awo chitetezo kalasi.

katswiri Nsonga

matepi LED, kakakulu amene asankhidwa mogwirizana ndi malamulo onse, ntchito kwa nthawi yaitali. Koma izi ziri zoona zokha pa nkhani ya kugula zopangidwa kudziwika ndi kutsimikiziridwa. Akatswiri osati kugula wotsika ndi otsika khalidwe tepi.

mankhwala Chokhalitsa alibe m'mbali akhakula tepi, kapena kuzilemba LEDs crookedly. Choncho, musanasankhe chinthu m'pofunika kufufuza kuyatsa unit. Kuyambira zopangidwa zotsika mtengo koma apamwamba, akatswiri kuonetsetsa Feron, Maxus. Malinga ndi mayankho a owerenga wamba, monga LED Mzere adzakhala zaka zosachepera 5.

Njira wapadera kusankha liyenela anatsogolera Mzere. Mphamvu ndi makhalidwe wapadera pogwiritsa kulola kugula ndi kulumikiza mtundu abwino kwambiri a mankhwala molondola.
