Chii chinofanira kuitwa kana mwenje uchidzima panguva yekudzima?

Matanho emwenje e LED, nechiedza chavo chakapfava, mamiriro akasiyana-siyana ekuisa uye mabasa ekudzima anochinjika, zvave zvinhu zvinonyanya kufarirwa pakugadzirisa dzimba, mwenje yekutengeserana uye kushongedza nzvimbo. Zvisinei, vashandisi vazhinji vanosangana nedambudziko rekudzima kana vachishandisa basa rekudzima. Vashandisi vazhinji vanotenda kuti "kudzima zvishoma hakukanganisi kushandiswa", asi vanokundikana kufunga nezvenjodzi dzinogona kuitika: Chekutanga, zvinokanganisa ruzivo rwekuona, kunyanya munzvimbo dzakadai semakamuri ekurara, makamuri ekudzidzira, uye mashopu ekutengeserana uko kugadzikana kwechiedza kunodiwa zvakanyanya. Kudzima kunogona kukonzera kuneta kwekuona, musoro, uye kutokurumidzisa kukura kwemyopia yevana kana vakasangana nekudzima kushoma kwenguva yakareba. Kunewo mamwe matambudziko akatevedzana.
1 Yakajairika: Kusawirirana kweDimmer neLight Strip (60% yeMatambudziko)
Ichi ndicho chikonzero chekutanga chandinoona—zvishoma nezvishoma. Mitsetse ye LED haina kufanana nemabarabhu ekare e incandescent; haugone kungodzikisa voltage kuti udzikise. Inoda kudzora magetsi kwakaringana uye kutumira masaini. Kana dimmer yako ne strip zvisingataure mutauro mumwe chete, flicker inyaya iripo. Ngatirambei tichiita izvi zviri nyore—hezvino zvekutarisa:
- Rudzi rweDimmer Risiri Rwechokwadi: Hazvina kukodzera madhimaki emwenje ye LED. Zvakare, madhimaki akasiyana (akadai seRGBW kana anogona kutumirwa) anoshandisa "makodhi" akasiyana ekudimaki—kusanganisa madhimaki emhando dzakasiyana kunokanganisa zvese. Semuenzaniso, a5V WS2812B stripinoda chiratidzo che800kHz, nepo12V DMX stripzvinoda zvayo—hazvizoshandi pamwe chete.
- Kusawirirana kwePWM Frequency: Mazhinji ma LED controllers akanaka ane PWM frequency iri pakati pe200-1000Hz—maziso ako haakwanise kuona kupenya kuri pamusoro pe200Hz. Asi ma dimmer nema strips akachipa? Ma frequency avo anowanzova 120-180Hz chete. Paunodzikisa kupenya, kupenya ikoko kunoonekwa—uye zvinonetsa. Kungovandudza kuita dimmer iri nani kunogadzirisa izvi.
- Kusawirirana Kwemutoro: Dhimeri yega yega ine "nzvimbo inotapira" yesimba rayo. Kana zvidimbu zvako zvikashandisa simba shoma pane simba redhimeri (rakajairika kune thyristor dimmers dzekare) kana kupfuura simba rayo guru, uchatanga kupenya. Zvakafanana nekuedza kushandisa girobhu diki remwenje padhimeri rakagadzirirwa chandelier hombe—hazvishande zvakanaka.

2 Zviri nyore Kupotsa: Simba Rinotadza Kuwanikwa
Funga nezvemagetsi se "moyo" wetambo yako ye LED—kana isina simba kana kuti isina kunaka, zvese zvinofamba zvisina kunaka. Ndakaona vatengi vazhinji vachiregeredza izvi, asi ingori mhinduro iri nyore kana wangoziva zvekutsvaga. Heano matambudziko anowanzo sangana nawo emagetsi:
- Simba Remhando Yepasi: Simba remagetsi rakachipa rinocheka makona—havana ma capacitor akakwana ekusefa simba remagetsi nemazvo. Izvi zvinoreva kuti simba reDC ravanoburitsa rine "ripple" yakawanda (simba diki reAC rakasanganiswa). Paunodzima strip, simba remagetsi rinochinja nekukurumidza, zvichikonzera kudzikira kwevoltage—uye kudzima. Ndakaedza simba remagetsi re12V rakachipa apo ripple iyi iri 10% yevoltage yakayerwa—izvozvo zvakawandisa, uye zviri nyore kugadzirisa nekuvandudza simba remagetsi remhando yepamusoro.
- Kusakwana kwemagetsi kana simba: Voltage inobuda yemagetsi inofanira kunge yakafanana neye light strip, uye simba rinofanira kunge rakakwira ne30% kupfuura simba rese relight strip. Nenzira iyi chete ndipo panogona kuva nesimba rakakwana rekufambisa light strip.
- Simba remagetsi richikwegura kana kupisa zvakanyanya: Kana simba remagetsi rikashandiswa kwenguva yakareba, zvikamu zvemukati zvinokwegura, uye simba remagetsi rinobuda harina kugadzikana, izvo zvinogona kukonzeramitsetse yakapfavakupenya nguva nenguva.

3 Zviri Nyore Kugadzirisa: Kubata waya zvisina kunaka kana Kubatana Kwakareruka
Paunenge uchigadzira tambo dzemwenje dzaunozviitira wega, kazhinji nekuda kwewaya dzisina kunaka kana kubatana, tambo dzemwenje dzinodzima.
- Waya dzisina kusimba: Kubatana pakati pemitsetse yemwenje nemagetsi, pamwe chete nedhimmer, hazvina kugadzirwa nemazvo, zvichikonzera kuti magetsi apedzisire achinja-chinja uye adzima.
- Kudzosera kumashure ma terminals akanaka neasina kunaka: Izvi zvinokonzeresa kudzima-dzima panguva yekudzima, kupenya kusina kujairika, uye kutotadza kudzimwa zvakanaka
- Chikanganiso chenzira yekubatanidza: Kana tambo dzakawanda dzechiedza dzakabatana mumutsara, kubatana kwakafanana hakuna kushandiswa, zvichikonzera kugoverwa kwemagetsi kusina kuenzana.
- Kuoresa kwenzvimbo yekubata: Mushure mekushandiswa kwenguva refu, chimiro chemuchina wechiedza chinooresa uye chinoshanduka kuita chitema, zvichikonzera kutenderera kwemagetsi kusina kugadzikana uye kupenya kwemuchina wechiedza.

4 Zvimwe Zvinokonzera: Kutsveyama Pachako kana Kupindira Kwezvakatipoteredza
- Chidimbu chemwenje chisina kunaka: Zvidimbu zvakachipa zvinoshandisa mabhero e LED emhando yepamusoro uye soldering isina kunaka. Mabhero anogona kupera kana kudonha, kana kuti bhero haribvise kupisa zvakanaka. Paunoridzima, tembiricha inokwira, uye bhero rinodzima kwenguva pfupi—zvichikonzera kudzima. Mamwe mabhero akachipa ane zvikanganiso zvemagadzirirwo zvinoita kuti zvisakwanise kudzimwa pasina kudzima. Kana zvakadaro, tsiva bhero racho kuitatambo isina kupenya.
-Kupindirana kwemagetsi: Kana chitofu chemhepo, firiji, kana microwave chikavhurwa kana kudzimwa, chinogadzira kupindirana kwemagetsi, izvo zvinokanganisa chiratidzo chePWM uye zvinoita kuti mwenje upfuure.
- Kusapisa zvakanaka: Matandi emwenje akaiswa munzvimbo yakamanikana pasina matanho akakodzera ekudzima kupisa. Munguva yekudzima, shanduko dzesimba dzakaita kuti tembiricha iwedzere, zvichikonzera kushanda kusina kujairika kwemabhera emwenje nedhiraivha chip. Nekuda kweizvozvo, matandi emwenje aidzima.

Nezvemamiriro ezvinhu apo chiratidziro chiri kudzima, heano mamwe magadzirisiro ekugadzirisa.

Danho 1: Tarisa Wiring
Iri ndiro danho rekutanga randinotora nemutengi wese—zviri nyore, hazvidhuri, uye zvinogadzirisa matambudziko akawanda ari nyore. Heino zvekuita:
1. Kudzima magetsi: Bvisa chivharo chemagetsi kudzivirira njodzi yekubatwa nemagetsi.
2. Tarisa mapango akanaka neasina kunaka: Iva nechokwadi chekuti mapango akanaka neasina kunaka ezvimedu zvemwenje, madhimmer, uye magetsi zvakabatana nemazvo. Kana zvakabatana nenzira isiriyo, gadzirisa divi rewaya woedzazve.
3. Kusimbisa ma connections: Tarisa kana ma connections ese akachengeteka; kana paine oxidation panzvimbo dzekubatanidza, pukuta ne alcohol.
4. Tarisa nzira yekubatanidza waya: Kana tambo dzakawanda dzemwenje dzakabatana panguva imwe chete, shandisa waya dzakafanana kuti usabatana nenguva imwe chete.
Mushure mekuongorora, ita bvunzo yekudzima magetsi panzvimbo yacho. Kana tambo yemwenje ikarega kupenya, zvinoratidza kuti dambudziko riri pawaya dzemagetsi; kana ichiri kupenya, zvinoda kugadziriswazve.

Danho rechipiri: Tarisa Simba remagetsi
1. Tarisa ma parameter emagetsi: Iva nechokwadi chekuti voltage inobuda nesimba remagetsi zvinoenderana nezvinodiwa ne light strip. Simba remagetsi rinofanira kunge rakapetwa ka1.2 kupfuura simba rese re light strip kudzivirira mutoro usina kukwana.
2. Kuedza kutsiva magetsi: Kana paine fungidziro yekuti pane matambudziko emhando yemagetsi, chinja nemagetsi akafanana uye ita bvunzo yekudzima magetsi.
3. Tarisa kana magetsi achichinja-chinja: Tarisa kana kudzima kunoitika panguva imwe chete nekutanga nekumiswa kwemidziyo yemagetsi ine simba guru. Kana zvikaitika, mudziyo unosimbisa magetsi unogona kuiswa pamagumo ekupinda kwemagetsi.

Danho rechitatu: Tarisa kana michina yekudzima chiedza iriyo sarudzo chaiyo
Kana waya dzemagetsi nemagetsi zviri zvakanaka, dambudziko ringangodaro nderekuti mudziyo unodzima magetsi hauenderane neTambo ye LEDUnogona kuedza mhinduro dzinotevera: Simbisa kuti strip ye LED iri kudzima sei: Tarisa kana strip ye LED iri monochrome, RGB, kana RGBW.

Aya ingori mhinduro dziri nyore. Kana ukasangana nematambudziko akaomarara ane chekuita nemwenje ye LED, ndapota inzwa wakasununguka kuashandisataura nesu.
