Shin kun taɓa kallon ƙaramar hasken LED mai haske kuma kun yi mamakin yadda yake aiki? Me yasa yake da irin wannan daidaitaccen haske kuma baya ƙonewa da sauri? Me yasa wasu LEDs suke haskakawa yayin da wasu ke dushewa da sauri? Duk waɗannan tambayoyin sun zo kan nau'in direban LED da aka yi amfani da su.
LEDs (Light Emitting Diodes) wani nau'in fasahar haske ne mai inganci, mai dorewa, kuma mai dorewa. Suna buƙatar direban LED don yin aiki daidai kuma zuwa cikakken ƙarfin su. Wannan sakon zai shiga cikin duniyar direbobin LED, musamman ma Direbobin Wutar Lantarki na Dindindin na yanzu da na yau da kullun na LED, kuma taimaka muku fahimtar wanda zai dace da bukatun hasken ku.
Idan kuna sha'awar LEDs ko kuna da aikin da ya haɗa da hasken LED, karanta don fahimtar waɗannan mahimman abubuwan gabaɗaya.
I. Gabatarwa
Takaitaccen Gabatarwa zuwa LEDs (Diodes masu Haskakawa)
Haske Emitting Diodes or LEDs na'urori ne na semiconductor waɗanda ke fitar da haske lokacin da wutar lantarki ta ratsa su. An san su da inganci da tsayin daka, wanda hakan ya sa su shahara don aikace-aikacen hasken wuta daban-daban, tun daga hasken gida zuwa siginar zirga-zirga har ma da na'urorin dijital.
Bayanin Bukatar Direbobin LED
Duk da yake masu inganci kuma masu amfani da su, LEDs suna aiki daban-daban da fitilun fitilu na gargajiya ko fitilu masu kyalli. Suna buƙatar takamaiman yanayin halin yanzu da ƙarfin lantarki don yin aiki yadda ya kamata, wanda direban LED ya sauƙaƙe.
Ba tare da direba ba, LED na iya zama mai zafi da rashin kwanciyar hankali, wanda zai haifar da mafi kyawun aiki, haske mara daidaituwa, ko ma kuna. Saboda haka, direban LED shine muhimmin sashi na kowane tsarin LED.
II. Fahimtar Direbobin LED
Ma'anar direban LED
An Direban LED wutar lantarki ce mai sarrafa kanta wacce ke daidaita ƙarfin da ake buƙata don LED ko kirtani (array) na LEDs. Yana tabbatar da cewa LEDs suna aiki a ƙarƙashin ƙayyadaddun yanayin su.
Matsayi da Muhimmancin Direbobin LED a Tsarin Hasken LED
Direbobin LED suna taka muhimmiyar rawa a tsarin hasken LED. Suna kula da ma'auni na halin yanzu da ƙarfin lantarki, wanda ke da mahimmanci don hana LEDs daga lalacewar thermal da kuma tabbatar da cewa suna aiki a mafi girman ingancin su.
Ba tare da direban LED mai dacewa ba, LEDs suna da saurin canzawa a cikin samar da wutar lantarki, wanda ke haifar da haske mara daidaituwa, canjin launi, flickering, da yuwuwar lalacewa. Don haka, direba mai kyau na LED yana da mahimmanci ga tsawon rai da aikin kowane tsarin hasken wuta na LED.
III. Direbobin LED na yau da kullun
Bayanin Direban LED na yau da kullun
A Direban LED na yau da kullun yana daidaita abubuwan da ake fitarwa a halin yanzu, yana kiyaye shi daidai ba tare da la'akari da ƙarfin shigarwa ko canje-canjen kaya ba. Wannan fasalin yana da mahimmanci don kunna LEDs tunda suna buƙatar ci gaba na yanzu don aiki daidai.
Yadda Direban LED na yau da kullun ke Aiki
Direban Constant Current yana daidaita wutar lantarki a fadin abin da ake fitarwa don kula da madaidaicin kwararar halin yanzu. Idan juriya a fadin LED ya karu saboda canje-canjen zafin jiki ko wasu dalilai, direba yana rage ƙarfin fitarwa don ci gaba da kasancewa a halin yanzu.
Ma'anar Runaway na thermal da yadda Direban LED na yau da kullun ke hana shi
Runaway thermal shine yuwuwar batun tare da LEDs. Yana faruwa a lokacin da karuwar zafin jiki ya haifar da karuwa a halin yanzu, yana haifar da LED don zafi fiye da haka, yana haifar da sake zagayowar lalacewa wanda zai iya lalata LED.
Direbobi na yau da kullun suna hana hakan ta hanyar kiyaye tsayayyen halin yanzu duk da canjin yanayin zafi, yadda ya kamata yana rage haɗarin guduwar zafi.
Fa'idodin Amfani da Direbobin LED na yau da kullun
Direbobi na yau da kullun suna tabbatar da daidaiton haske a duk LEDs da aka haɗa a jeri, suna haɓaka daidaituwar gani gaba ɗaya. Hakanan suna da tasiri wajen guje wa ƙonewar LED ko guduwar zafi.
Matsaloli masu yiwuwa ko Iyakoki
Duk da fa'idodin su, Direbobi na yanzu na iya samun iyaka. Misali, suna buƙatar daidaitaccen daidaitawa tare da buƙatun LED na yanzu kuma gabaɗaya sun fi direbobin Constant Voltage tsada.
IV. Direbobin Wutar Lantarki na LED
Bayanin Direbobin Wutar Lantarki na Constant Voltage LED
A Direban Wutar Lantarki na LED yana kiyaye ƙayyadaddun wutar lantarki ba tare da la'akari da zana na yanzu na kaya ba. Ana amfani da wannan sau da yawa don tsarin LED wanda aka riga an sanye shi da resistors ko iko na yanzu, kamar LED tsiri fitilu.
Yadda Direbobin Wutar Lantarki na LED ke Aiki
Direban Voltage Constant yana kiyaye irin ƙarfin lantarki iri ɗaya a duk abin da yake fitarwa, ba tare da la'akari da nauyin da ke ciki ba. Wannan yana da amfani musamman lokacin da ake kunna LEDs da yawa da aka haɗa a layi daya.
Fa'idodin Amfani da Direbobin Wutar Lantarki na LED
Direbobin wutar lantarki na yau da kullun sun san ƙira da injiniyoyin shigarwa, waɗanda zasu iya sauƙaƙe tsarin saitin. Suna iya yuwuwar rage farashin a cikin manyan aikace-aikacen aikace-aikacen saboda madaidaiciyar ƙira.
Matsaloli masu yiwuwa ko Iyakoki
Ɗaya daga cikin ƙayyadaddun ƙayyadaddun masu tuƙi na Constant Voltage shine dogaro da ƙarin abubuwan haɗin gwiwa don sarrafawa na yanzu a kowace naúrar LED. Wannan na iya sa tsarin ya fi rikitarwa kuma mai yuwuwar rashin abin dogaro a cikin dogon lokaci.
Misalai na Aikace-aikace
Aikace-aikace na yau da kullun don direbobin Voltage Constant sun haɗa da fitilun ƙasan majalisar da aikace-aikacen tsiri na LED inda aka haɗa fitattun fitilun a layi daya.
V. Kwatanta Tsakanin Direbobi na LED na Constant Current da Constant Voltage LED
Tebur mai zuwa yana kwatanta bambance-bambancen maɓalli tsakanin Direbobi na LED na Constant Current da Constant Voltage LED:
| M Yanzu | Volaƙwalwar Wuta | |
| Output | M Yanzu | Volaƙwalwar Wuta |
| Yana Hana Guduwar Thermal | A | A'a |
| Daidaitaccen Haske | A | Ya dogara da Ƙarin Gudanarwa na Yanzu |
| Yi amfani da Halin | High Power LEDs | LED tube, sanduna, da dai sauransu. |
Zaɓin tsakanin su biyun ya dogara da takamaiman aikace-aikacen. Direbobi na yau da kullun galibi ana fifita su don manyan LEDs, inda sarrafa zafi ke da mahimmanci. A gefe guda, ana amfani da direbobin Constant Voltage don samfuran LED tare da LEDs masu yawa da aka haɗa tare, kamar fitilun igiya na LED, tube LED, da sandunan LED.
VI. Zabar Direban LED ɗin Dama
Abubuwan da za a yi la'akari da su Lokacin zabar Tsakanin Direbobin LED na yau da kullun da na yau da kullun na wutar lantarki
Zaɓin direban LED ɗin da ya dace ya dogara da abubuwa daban-daban, gami da takamaiman LED ko buƙatun ƙarfin lantarki na tsararru, lamba da tsari na LEDs a cikin tsarin (jeri ko a layi daya), da yanayin wutar lantarki na mahallin ku.
Nasihu don Zaɓin Direban LED ɗin Dama don takamaiman Aikace-aikace
Ana buƙatar direban Voltage na dindindin idan LED ko tsararru sun ƙayyadad da takamaiman irin ƙarfin lantarki. Koyaya, idan kuna aiki tare da manyan LEDs, direba na yanzu zai kasance da fa'ida don hana guduwar thermal da tabbatar da daidaiton haske.
Koma zuwa ƙayyadaddun masana'anta kuma tuntuɓi ƙwararrun haske idan kuna buƙatar bayani.
VII. Tambayoyi
VIII. Kammalawa
Direbobin LED, ko Constant Current ko Constant Voltage, suna taka muhimmiyar rawa wajen kiyaye aiki da tsayin LEDs ɗin ku. Duk da yake duka biyun suna da fa'idodi da iyakancewa, zaɓinku yakamata ya dogara ne akan takamaiman buƙatun tsarin LED ɗin ku.
