Qeexitaan sare ilaalinta isha keliya ayaa aad uga muhimsanbandhig LED gudaha
Sababtoo ah wasakhowga iftiinka daran ee shaashadaha waaweyn ee LED-ka, Guangzhou waxay soo saartay "amarka xaddidaadda LED" ee ugu horreeya ee Shiinaha si loo xakameeyo wasakhowga iftiinka, kaas oo mamnuucaya furitaanka bandhigyada elektaroonigga ah ee LED-ka laga bilaabo 22:30 habeenkii ilaa 7:30 soo socda maalin.Kadib, marka shaashadda LED-ka ay soo gasho qolka, wasakhowga iftiinka ayaa hoos u dhacaya, laakiin diiradda dareenka ayaa loo wareejiyaa heerka "caafimaadka iyo raaxada".Muqaal noocee ah oo gudaha LED ah ayaa caafimaad qaba oo raaxo leh?Sida loo qiimeeyo caafimaadka iyo raaxadabandhigyada LEDwaxay noqotay walaac.
Macaamiisha inta badan isticmaala muraayadaha LED-ka waxay ogaan doonaan haddii ay isticmaalaan muraayadaha LED-ka ee qolalka shirarka hoteelka, indhahooda ayaa guban doona marka ay daawadaan wakhti dheer.Goobta duubista barnaamijka TV-ga, waxa ku jira muraayadda LED-ku si degdeg ah ayey u shidaysaa, dhalaalkuna si degdeg ah ayuu isu beddelaa, taas oo sidoo kale ka dhigi doonta in dhegaystayaashu ay dareemaan raaxo.Qaar ka mid ah muraayadaha LED-yada ee tayadoodu hooseyso ayaa laga yaabaa inay xitaa keenaan indho qalalan, indho-biyood iyo indho beel.Tani waa sababta muraayadda gudaha ee LED-ka ee gudaha ma aha oo kaliya in ay noo keento tayada sawir cad oo muuqaal ah oo midab leh, laakiin sidoo kale waxay keentaa dhaldhalaalka waxyeellada u keena indhaha.
Qiimaynta iftiinka aan raaxada lahayn, dhammaan waddamada adduunka waxay leeyihiin habab u gaar ah.Habka tusmada iftiimaya ee CGI (CIE Glare Index) oo ay ku talisay CIE (Guddiga Caalamiga ah ee Iftiinka) ayaa ah habka tibaaxaha xisaabeed ee ka wanaagsan wakhtigan, kaas oo qiimayn kara iftiinka iftiimaya si dhamaystiran iyo si dhab ah.Odhaahdu waa:
Ed - Iftiin toos ah oo toos ah (lx) indhaha, oo ka imanaya isha iftiinka.
Ei – Iftiin toosan oo aan toos ahayn (lx) isha, xagga dambe.
L - dhalaalka isha dhalaalaysa (cd/m2).
ω– Cabbirka isha dhalaalaysa (Sr).
Tusiyaha booska P-Ghth (mawqifka booska).
Glare index waa tilmaame lagu saadaaliyo laguna qiimeeyo dhalaalka raaxada ee jawiga shaqada gudaha.Marka loo eego habka samaynta dhaldhalaalka, muraayadda shaashadda LED-ka waxaa loo qaybin karaa laba nooc: dhalaal toos ah, taas oo ay sababtay iftiinka sare ee shaashadda LED-ka iyo jihada xooggan ee isha iftiinka LED;Iftiinka milicsiga waxaa sababa isku-dhafka sare ee milicsiga ee qaar ka mid ah qalabka soo bandhiga LED iyo milicsiga xooggan ee ilaha iftiinka kale.
Dilaaga aragga 1: dhaldhalaalka tooska ah
Shaashada gudaha ee LED-ka waxaa guud ahaan lagu isticmaalaa qolalka shirarka ee hoteelada, garoomada ciyaaraha, TV-ga tooska ah, riwaayadaha iyo munaasabadaha kale.Marka ay isha bini’aadamku daawato wakhti dheer oo ay ku jirto masaafo yar, waxa isha bini’aadamka kacsi u noqon doonta dhalaalka tooska ah ee muraayada LED-ka.Ardayga isha wuu yaraanayaa, indhuhuna waxay dareemi doonaan raaxo la'aan.Daawashada muddada dheer waxay dhaawici doontaa indhaha.
Si looga hortago dhaldhalaalka tooska ah, dariiqa tooska ah waa in la yareeyo dhalaalka shaashadda LED-ka.Si kastaba ha noqotee, iyada oo la dhimayo iftiinka shaashadda LED-ka, waxay sidoo kale luminaysaa faa'iidada asaasiga ah ee shaashadda LED-ka gudaha - miisaanka cawl.Ciyaarta u dhaxaysa labadooda sidoo kale waa mid ka mid ah marinnada muhiimka ah ee "iftiin hooseeya iyo cawl sare" ee muraayadda muraayadda LED-ka ee gudaha gudaha.Shenzhen Lanke Electronics Co., Ltd. waxay jebisay marinkan farsamada iyada oo loo eegayo fahamkeeda qoto dheer ee codsiyada soo bandhigida LED gudaha iyo faa'iidooyinka farsamo ee lagu ururiyay 16 sano ee baakadaha LED.
Injineerada Lanke waxay soo saareen badeecooyin baakad ah oo loogu talagalay shaashadda soo-bandhigidda LED-ka taas oo si weyn u yarayn karta dhaldhalaalka - Blackcrystal 2121 iyada oo loo marayo horumarrada agabka baakadaha LED-ka iyo naqshadeynta habka.Si ka duwan isha caadiga ah ee isha iftiinka gudaha ee LED, crystal madow 2121 wuxuu qaataa tignoolajiyada iftiiminta iftiinka dusha.Marka la barbar dhigo isha isha laydhka ah ee isku nooc ah, isha ilayska oogada waxa ay leedahay astaamo ifaya oo hooseeya sababtoo ah iftiinka weyn ee ka baxaya oogihiisa oo isku mid ah, taas oo aad u yaraynaysa dhiirigelinta isha iftiinka ee isha aadamaha, aadna u yaraynaysa Dhibaatooyinka iftiimaya ee ka jira alaabada isha iftiinka iftiinka LED ee dhaqanka.
Isla mar ahaantaana, isha iftiinka dusha sare ayaa sidoo kale si buuxda u tirtiraya walxaha gaarka ah ee muraayadda LED-ka (taas oo samayn doonta wasakh iftiin leh oo waxyeello u geysan doonta xuubka daawadayaasha), waxay kordhisaa jilicsanaanta sawirka, waxay ka dhigtaa sawirka jilicsan, saaxiibtinimo iyo saaxiibtinimo. , waxayna wanaajisaa hufnaanta sawirka shaashadda LED-ka.
Dilaaga aragga 2: dhaldhalaalka muuqda
Marka laga soo tago is- iftiiminta, dhalaalka shaashadda LED-ka ayaa sidoo kale waxaa keena iftiinka iftiinka xoogga leh ee deegaanka ku hareeraysan dusha sare ee alaabta shaashadda LED.Gaar ahaan muraayadda asalka ah ee marxaladda LED, dhaldhalaalka milicsiga ayaa gaar ahaan halis ah.Ka-hortagga iyo xakamaynta dhaldhalaalka noocan oo kale ah, walxaha milicsiga ayaa inta badan la tixgeliyaa.Qalabka PPA-ga madow ee leh muraayad hoose ayaa loo xushay crystal madow 2121. Isla mar ahaantaana, tignoolajiyada daaweynta atomization ee dusha sare ayaa sidoo kale loo isticmaalaa si loo yareeyo hantida milicsiga ee dusha sare ee kolloidalka inta lagu jiro habka iftiinka shaashadda.Marka la barbar dhigo kuulka nalka cad iyo kuul madow ee caadiga ah, crystal madow wuxuu yarayn karaa iftiinka milicsiga 70%, hoos u dhigista dhaldhalaalka iftiimaya ee uu keeno iftiinka jawiga.
Iyadoo diiradda la saarayo tayada alaabta LED, Lanke Electronics waxay wax badan ka ogtahay badbaadada iyo caafimaadka alaabta LED.Shaashadda gudaha ee LED-ka ee leh aaladaha soo saara wejiga waa sheyga ilaalinta indhaha ee warshadaha soo bandhigista LED.Lanke Electronics waxa ay ka dhigtaa iftiinka ay shidayso laambada LED-ka mid jilicsan, dabiici ah oo aan waxyeello u geysan indhaha iyada oo loo marayo tignoolajiyada iftiiminta iftiinka iftiinka iyo tignoolajiyada daawaynta atomization dusha sare, iyada oo hoos u dhigaysa dhaldhalaalka ifafaale ee shaashadda LED-ka, taas oo si weyn u hagaajinaysa ifafaalaha quruxda badan. ee muraayadda gudaha ee LED-ka, iyo gaaritaanka saamaynta si wax ku ool ah looga ilaaliyo indhaha waxyeellada oo gebi ahaanba baabi'inta isha iftiinka.
Xilliga gudaha gudaha gudaha gudaha garoonka yar yar iyo nolosha caqliga leh, bandhiga LED waa inuusan noqon mid midab leh oo leh nolol dheer oo adeeg ah, laakiin sidoo kale tixgeli badbaadada iyo raaxada daawadayaasha.Shaashad caafimaad qabta oo keliya ayaa u dhow in la isticmaalo
