Mwenje ye LED ikozvino ndiyo inonyanya kufarirwa tekinoroji. Anenge munhu wese anoziva nezve akawanda mabhenefiti anopihwa ne LED zvigadziriso, kunyanya nyaya yekuti iwo anowedzera simba uye anogara-anogara-akareba kupfuura echinyakare mwenje zvigadziriso. Nekudaro, vanhu vazhinji havana ruzivo rwakawanda pamusoro peiyo tekinoroji iri kuseri kwemwenje we LED. Mune ino post, tinotarisa kuti pasi peiyo tekinoroji yemwenje ye LED kuitira kuti tinzwisise kuti marambi e LED anoshanda sei uye kuti mabhenefiti ese auya papi.

Chitsauko 1: Chii chinonzi LEDs uye anoshanda sei?

Nhanho yekutanga yekunzwisisa tekinoroji yekuvhenekesa kwe LED ndiko kunzwisisa kuti ma LED chii. LED inomirira chiedza emitting diodes. Aya ma diode ari semiconductor mune zvakasikwa, izvo zvinoreva kuti vanogona kuitisa magetsi ikozvino. Kana magetsi emagetsi akaiswa pachiedza emitting diode, mhedzisiro ndeyekuburitswa kwesimba nenzira yephotons (light energy).

Nekuda kwekuti zvigadziriso zve LED zvinoshandisa semiconductor diode kugadzira mwenje, ivo vanonzi semidziyo yakasimba yechiedza. Mamwe marambi akasimba anosanganisira organic light emitting diodes uye polymer light-emitting diode, ayo anoshandisawo semiconductor diode.

Chitsauko 2: Chiedza che LED uye tembiricha yemavara

Zvizhinji zvezvigadziriso zve LED zvinoburitsa chiedza chichena muruvara. Chiedza chichena chinoiswa muzvikamu zvakasiyana zvichienderana nekudziya kana kutonhora kwechimwe nechimwe chegadziriso (saka tembiricha yeruvara). Aya emhando tembiricha classifications anosanganisira:

Warm White - 2,700 kusvika 3,000 Kelvins
Neutral white - 3,000 kusvika 4,000 Kelvins
Pure White - 4,000 kusvika 5,000 Kelvins
Zuva Rakachena - 5,000 kusvika ku6,000 Kelvins
Inotonhorera White - 7,000 kusvika 7,500 Kelvins
Muchena inodziya, ruvara runogadzirwa ne LEDs rune yellow hue, yakafanana neiyo incandescent mwenje. Sezvo kupisa kwemavara kuchikwira, chiedza chinova chichena pakuonekwa, kusvikira chasvika zuva chena ruvara, rwakafanana nechiedza chechisikigo (chiedza chemasikati kubva kuzuva). Sezvo tembiricha yeruvara ichiramba ichiwedzera, mwenje wechiedza unotanga kuve neblueish hue.

Chinhu chimwe chete chaunofanira, zvisinei, kucherechedza pamusoro pemwenje emitting diodes ndechekuti haaburitse mwenje chena. Iwo madhiodhi anowanikwa mune matatu ekutanga mavara: tsvuku, girini, uye bhuruu. Rudzi ruchena runowanikwa mune mazhinji ma LED zvigadziriso runouya nekusanganisa aya matatu ekutanga mavara. Chaizvoizvo, kusanganiswa kwemavara muma LED kunosanganisira kubatanidza mwenje wakasiyana wavelengths maviri kana anopfuura diode. Nokudaro, kuburikidza nekusanganiswa kwemavara, zvinokwanisika kubudirira chero ipi zvayo yemavara manomwe anowanikwa muchiedza chinooneka chechiedza (mavara emuraraungu), anobudisa ruvara ruchena apo ose akabatanidzwa.

Chitsauko 3: LED uye simba rekushandisa

Chimwe chinhu chakakosha che tekinoroji yekuvhenekesa kwe LED ndiko kugona kwavo kwesimba. Sezvatotaurwa, anenge munhu wese anoziva kuti ma LED ane simba rinoshanda. Zvisinei, nhamba yakanaka yevanhu havazivi kuti simba resimba rinouya sei.

Chinhu chinoita kuti LED iwedzere simba kupfuura mamwe matekinoroji ekuvhenekesa inyaya yekuti maLED anoshandura rinenge rose remagetsi akaiswa (95%) kuita simba rakajeka. Pamusoro peizvozvo, maLED haabudise infrared radiation (chiedza chisingaoneki), iyo inotungamirwa nekusanganisa iwo wavelengths yemavara eiyo diode mune imwe neimwe fixture kuti iwane chete chena ruvara wavelength.

Kune rimwe divi, mwenje weiyo incandescent unongoshandura chikamu chidiki chete (chinenge 5%) chesimba rinopedzwa kuita mwenje, uye imwe yese ichiparadzwa nekupisa (inenge 14%) uye infrared radiation (inenge 85%). Naizvozvo, nehunyanzvi hwekuvhenekesa kwechinyakare, simba rakawanda rinodiwa kuitira kuburitsa kupenya kwakakwana, nema LED anoda simba shoma kuti abudise kupenya kwakafanana kana kwakawanda.

Chitsauko 4: Kupenya kunopenya kwezvigadziriso zve LED

Kana iwe wakatenga incandescent kana fluorescent light bulbs munguva yakapfuura, iwe unoziva nezve wattage. Kwenguva yakareba, wattage yaive nzira inogamuchirwa yekuyera chiedza chinogadzirwa nefixture. Nekudaro, kubva pakuuya kweiyo LEDs fixture, izvi zvachinja. Chiedza chinogadzirwa ne LED chinoyerwa muchiedza chinopenya, icho chinotsanangurwa sehuwandu hwesimba rinobudiswa nechiedza chechiedza kumativi ose. Chiyero chechiyero cheruminous flux ndeye lumens.

Chikonzero chekushandura chiyero chekupenya kubva pamvura kusvika pakupenya imhaka yekuti ma LED ari mashoma emagetsi emagetsi. Naizvozvo, zvine musoro kuona kupenya uchishandisa chinopenya chinobuda panzvimbo pesimba rinobuda. Pamusoro peizvi, zvigadziriso zvakasiyana zve LED zvine hunyanzvi hwekupenya hwakasiyana (kugona kushandura ikozvino magetsi kuita mwenje kubuda). Naizvozvo, zvigadziriso zvinoshandisa huwandu hwakafanana hwesimba zvinogona kuve nekupenya kwakasiyana kwakasiyana.

Chitsauko 5: LEDs uye kupisa

Mafungiro akajairika pamusoro pezvigadziriso zve LED ndezvekuti hazviburitse kupisa- nekuda kwekuti zvinotonhorera pakubata. Zvisinei, ichi hachisi chokwadi. Sezvatotaurwa pamusoro apa, chikamu chidiki chesimba rinoiswa muchiedza emitting diode chinoshandurwa kuita kupisa simba.

Chikonzero nei zvigadziriso zve LED zvichitonhorera kukubata ndechekuti chikamu chidiki chesimba chinoshandurwa kuita kupisa simba hachina kuwanda. Pamusoro pazvo, zvigadziriso zve LED zvinouya nemasinki ekupisa, izvo zvinobvisa kupisa uku, izvo zvinodzivirira kupisa kwemwenje emitting diode uye maseketi emagetsi ezvigadziriso zve LED.

Chitsauko 6: Hupenyu hwese hwezvigadziriso zve LED

Pamusoro pekugona kushanda nesimba, maLED light fixtures ane mukurumbira zvakare nekuda kwesimba rawo. Zvimwe zvigadziriso zve LED zvinogona kugara pakati pe50,000 uye 70,000 maawa, iyo ingangoita 5 times (kana kutopfuura) kureba kana ichienzaniswa nedzimwe incandescent uye fluorescent zvigadziriso. Saka, chii chinoita kuti magetsi e LED agare kwenguva refu kupfuura mamwe marudzi echiedza?

Zvakanaka, chimwe chezvikonzero chine chekuita nenyaya yekuti mwenje we LED yakasimba nyika, nepo incandescent uye mwenje wefluorescent inoshandisa magetsi filaments, plasma, kana gasi kuburitsa chiedza. Mafilamu emagetsi anopera nyore nyore mushure menguva pfupi nekuda kwekupisa kwekupisa, nepo magirazi egirazi anoisa plasma kana gasi ari nyore kukuvara nekuda kwekukanganisa, kuzunguzika, kana kudonha. Izvi zvigadziriso zvemwenje hazvina kusimba, uye kunyangwe zvikararama kwenguva yakakwana, hupenyu hwavo hupfupi zvakanyanya kana zvichienzaniswa ne LEDs.

Chinhu chimwe chekucherechedza nezve LED uye hupenyu hwese ndechekuti haatsva senge fluorescent kana incandescent bulbs (kunze kwekunge ma diode achipisa). Panzvimbo iyoyo, iyo inopenya inopenya yemwenje ye LED inodzikira zvishoma nezvishoma nekufamba kwenguva, kudzamara yasvika 70% yepakutanga inopenya kubuda.

Panguva ino (inodanwa seL70), kushatisa kunopenya kunova kucherechedzwa kuziso remunhu, uye mwero wekuderera unowedzera, zvichiita kuti kuenderera mberi kwekushandiswa kwezvigadziriso zve LED kusashande. Izvo zvigadziriso zvinoonekwa kunge zvasvika kumagumo ehupenyu hwavo panguva ino.
