Ma LED ari Light Emitting Diodes: zvinhu zvemagetsi zvinoshandura simba remagetsi rakananga kuchiedza kuburikidza nekufamba kwema electron mukati me diode material.Ma LED akakosha nekuti, nekuda kwekushanda kwawo uye kushomeka kwesimba rekushandisa, atova chinotsiva mazhinji akajairika magetsi.
Iyo Surface Mounted Device (SMD) LED ndeye 1 LED pane redunhu bhodhi, iyo inogona kunge iri pakati-simba kana yakaderera simba uye isinganyanye kunzwa kupisa chizvarwa kupfuura COB (Chips On Board) LED.MaSMD LEDs anowanzo kuisirwa paPrinted Service Board (PCB), bhodhi redunhu iro ma LED anotengeswa nemichina.Kana nhamba shoma ye LED dzine simba rakanyanya kushandiswa, kugoverwa kwekupisa paPCB iyi hakuna kunaka.Zviri nani kushandisa yepakati-simba LED mune iyo kesi, nekuti kupisa kunobva kwapatsanurwa zviri nani pakati peiyo LED uye redunhu bhodhi.Bhodhi redunhu rinofanirawo kurasikirwa nekupisa.Izvi zvinowanikwa nekuisa iyo PCB pane aruminiyamu mbiri.Zvigadzirwa zvemhando yepamusoro zvemwenje zve LED zvine chimiro chealuminium kunze kuitira kuti tembiricha itonhodze mwenje.Zvisikwa zvakachipa zvine bhokisi repurasitiki, sezvo plastiki yakachipa kupfuura aluminium.Izvi zvigadzirwa zvinongopa zvakanaka kupisa kupisa kubva ku LED kuenda kune base plate.Kana iyo aluminium ikasarasikirwa nekupisa uku, kutonhora kunoramba kuine dambudziko.
Chiyero che lumen pa watt (lm/W) chinoratidza kushanda kwerambi.Iyo yakakwirira kukosha uku, simba shoma rinodiwa kuti ribudise huwandu hwechiedza.Ndokumbira utarise kana kukosha uku kwakatemerwa mwenje sosi kana luminaire yese kana ma LED anoshandiswa mairi.Ma LED pachawo ane kukosha kwepamusoro.Pane nguva dzose kurasikirwa mukubudirira, semuenzaniso kana vatyairi uye optics vakaiswa.Ichi ndicho chikonzero nei maLED anogona kuve nekubuda kwe180lm/W, ukuwo kubuda kweruminaire yese kuri 140lm/W.Vagadziri vanodiwa kuti vataure kukosha kwechiedza chechiedza kana mwenje.Kubuda kweruminaire kune yekutanga pamusoro peiyo mwenje sosi kubuda, nekuti ma LED luminaires anoongororwa sese.
Chinhu chesimba chinoratidza hukama pakati pesimba rekuisa uye simba rinoshandiswa kuita kuti LED ishande.Pachine kurasikirwa mu LED machipisi uye vatyairi.Semuenzaniso, mwenje we100W LED ine PF ye0.95.Muchiitiko ichi, mutyairi anoda 5W kushanda, zvinoreva 95W LED simba uye 5W mutyairi simba.
UGR inomiririra Unified Glare Rating, kana kukosha kwekupenya kwemwenje sosi.Iyi inhamba yakaverengerwa yedhigirii yekupofumadza kwe luminaire uye yakakosha pakuongorora kunyaradza.
Iyo CRI kana Ruvara Rendering Index indekisi yekuona kuti mavara echisikigo anoratidzwa sei nechiedza chemwenje, ine kukosha kwereferensi kune halogen kana incandescent rambi.
Standard Deviation Color Matching (SDMC) iyuniti yekuyera yemusiyano weruvara pakati pezvigadzirwa zvakasiyana mukuvhenekesa.Kushivirira kwemavara kunoratidzwa mumatanho akasiyana eMac-Adam.
DALI inomirira Digital Addressable Lighting Interface uye inoshandiswa mukutarisira chiedza.Mune network kana yekumira-yega mhinduro, imwe neimwe inokwana inopihwa kero yayo.Izvi zvinobvumira mwenje wega wega kuti ugone kuwanikwa uye kudzorwa (pa - off - dimming).DALI ine 2-waya dhiraivha iyo inomhanya yakaparadzana nemagetsi uye inogona kuwedzerwa nekufamba uye mwenje sensors pakati pezvimwe zvinhu.
Iyo LB standard iri kuwedzera kutaurwa mune mwenje zvirevo.Izvi zvinopa chiratidzo chakanaka chemhando, zvese maererano nekudzoreredza kwechiedza uye kutadza kwe LED.Iko 'L' kukosha kunoratidza huwandu hwekupora kwechiedza mushure mehupenyu hwese.L70 mushure memaawa ekushanda e30,000 inoratidza kuti mushure memaawa ekushanda kwe30,000, 70% yechiedza chinoramba chiripo.L90 mushure meawa 50,000 inoratidza kuti mushure memaawa ekushanda e50,000, 90% yechiedza inosara, nokudaro inoratidzira hukuru hwepamusoro.Iko 'B' kukosha kwakakoshawo.Izvi zvine chekuita neperesenti inogona kutsauka kubva pamutengo weL.Izvi zvinogona semuenzaniso kukonzerwa nekutadza kwe LEDs.L70B50 mushure memaawa 30,000 inowanzoitika.Zvinoratidza kuti mushure memaawa ekushanda e30,000, 70% yehuwandu hutsva hwechiedza hunosara, uye kuti huwandu hwe50% hunotsauka kubva pane izvi.Iko kukosha kweB kunobva pane yakaipisisa-mamiriro ezvinhu.Kana iyo B kukosha isina kutaurwa, B50 inoshandiswa.PVTECH luminaires yakayerwa L85B10, iyo inoratidza hupamhi hwemhando yemwenje yedu.
Motion detectors kana kuvapo masensa musanganiswa wakanakisa kuti ushandiswe nemwenje we LED, nekuti anogona kubatidza nekudzima zvakananga.Mhando iyi yekuvhenekesa yakanakira muhoro, kana chimbuzi, asi inogona zvakare kushandiswa munzvimbo dzakasiyana siyana dzeindasitiri uye matura uko vanhu vari kushanda.Mazhinji magetsi e LED anoedzwa kuti ararame 1,000,000 ekuchinja nguva, izvo zvakanaka kwemakore ekushandiswa.Imwe muromo: zviri nani kuisa detector inofamba yakaparadzana kubva kune luminaire, sezvo mwenje sosi inogona kugara kwenguva refu kupfuura sensor.Uyezve, sensor isina kukwana inogona kudzivirira imwe mari yekuchengetedza.
Iyo tembiricha yekushanda ndiyo inonyanya kukanganisa hupenyu hwema LED.Iyo inokurudzirwa tembiricha yekushanda inoenderana nekutonhora kwakasarudzwa, mutyairi, maLED uye imba.Chikwata chinofanirwa kutongwa sechose, kwete zvikamu zvaro zvakasiyana.Mushure mezvose, iyo 'weakest link' inogona kuve inogadzirisa.Nzvimbo dzekushisa dzakaderera dzakanakira ma LED.Kutonhora uye kutonhora kwemasero kunonyanya kukodzera, nokuti ma LED anogona kubvisa kupisa zvakanaka.Sezvo kupisa kushoma kwatogadzirwa neLED pane nemwenje wakajairwa, kutonhora kunodawo simba shoma kuchengetedza tembiricha yayo.Kukunda-kukunda mamiriro!Munzvimbo dzinodziya zvishoma, mamiriro ezvinhu anova akasiyana.Kuvhenekera kwe LED kwakawanda kune tembiricha yekushanda ye35 ° Celsius, PVTECH mwenje unokwira kusvika 65 ° C!
Ma LED ane mwenje wakanangana nechiedza, kusiyana nemagetsi echinyakare anoparadzira mwenje paakapoteredza.Kana zvivheneko zve LED zvinopihwa zviratidziri, mwenje wakawanda uri pakati pedanda unosiya sisitimu usina kana kumbosangana neanoratidzira.Izvi zvinoderedza dhigirii rekugadzirisa kwechiedza chechiedza uye chinogona kuva chikonzero chekupofumadza.Malenzi anobatsira kutungamira chero chero mwenje wemwenje unoburitswa ne LED.
