Lipontšo tsa LED li hohle kajeno. Li mebala-bala ebile li khanyang, li eketsa mebala e mengata bophelong ba rona. Empa na u kile ua ipotsa hore na lipontšo tsee tsa LED li entsoe ka eng? Kajeno, a re bue ka likarolo tsa bohlokoa tsa lipontšo tsa LED - lifaha tsa lebone.
E 'ngoe ea likarolo tsa mantlha tsa lipontšo tsa LED ke lifaha tsa mabone, tseo boholo ba tsona e leng li-cubes kapa li-cuboids' me li na le litlhaloso tse fapaneng, joalo ka 3535, 3528, 2835, 2727 (2525), 2121, 1921, 1515, 1010, joalo-joalo. e laetsoeng ka har'a bracket ea tšepe, e tlatsitsoeng ka sekhomaretsi 'me e omisitsoe. Sebaka sa bona se khanyang hangata se khanya ka pele, 'me lithakhisa tsa lebone li ka rekisoa ka kotloloho ho boto ea potoloho ea PCB e nang le bokaholimo ba solder.
Lifaha tsa lebone tsa LED li na le litlhaloso tse fapaneng le mehlala ho ikamahanya le maemo a fapaneng a ts'ebeliso. Lefapheng la li-SMD tsa LED tsa ka hare, litlhaloso tse tloaelehileng tsa lebone la lebone li kenyelletsa 0505, 1010, 1515, 2121, 3528, joalo-joalo. Likopong tsa ka ntle, mehlala e tloaelehileng e kenyelletsa 1921, 2525, 2727, 3535, 5050, joalo-joalo. Mohlala, 0505 e bolela hore bolelele le bophara ba karolo ea LED ke 0.5mm ka bobeli.
Tlhaloso e qaqileng ea litlhaloso tsa lifaha tsa lebone
Boholo ba metric ea lifaha tsa lebone tsa 0505 ke 0.5mm×0.5mm, 'me khutsufatso ea indasteri ke 0505;
Boholo ba metric ba lifaha tsa lebone tsa 1010 ke 1.0mm×1.0mm, 'me khutsufatso ea indasteri ke 1010;
Boholo ba metric ea lifaha tsa lebone tsa 2121 ke 2.1mm×2.1mm, le khutsufatso ea indasteri ke 2121;
Boholo ba metric ea lifaha tsa mabone tsa 3528 ke 3.5mm×2.8mm, le khutsufatso ea indasteri ke 3528;
Boholo ba metric ea lifaha tsa lebone tsa 5050 ke 5.0mm×5.0mm, 'me khutsufatso ea indasteri ke 5050.
Ho na le bahlahisi ba bangata ba tsebahalang ba lifaha tsa lebone tsa LED lefatšeng,
Lifaha tsa lebone la LED li phuthetsoe ka litsela tse sa tšoaneng, ho kenyelletsa le li-plug-in tse tobileng, SMD, matla a phahameng le lifaha tsa lebone tsa COB LED. Ka nako e ts'oanang, lifaha tsa lebone la LED le tsona li mebala-bala, ho akarelletsa le khubelu, mosehla-tala, mosehla, lamunu, leputsoa, pherese, pinki le tšoeu.
Ha re khetholla lipalo tse ntle le tse mpe tsa lifaha tsa lebone la LED, re ka li khetholla ka ho tšoaea le ho hlophisa. Hangata, palo e ntle e tla tšoauoa e le letheba le lenyenyane kapa khutlotharo 'me e tla hlahella ka ntle; ha palo e mpe e sena matshwao mme e le kgutshoanyane hanyane ho feta palo e ntle. Haeba lipalo tse ntle le tse mpe li ke ke tsa khethoa, re ka sebelisa multimeter bakeng sa tlhahlobo.
Ho khetha mofuta o loketseng oa lebone la lebone la LED ho bohlokoa ho ntlafatsa ts'ebetso le bophelo ba lihlahisoa tsa LED. Ha re khetha lebitso, re hloka ho nahana ka lintlha tse ngata ho netefatsa hore mofuta o khethiloeng o fihlela litlhoko tsa rona.
Ka lebaka la mefokolo ea eona ea sebopeho, lifaha tsa lebone tsa LED tse otlolohileng li sebelisoa haholo lihlahisoa tsa kantle tse nang le libaka tse kang P10, P16, le P20. Lifaha tsa lebone tsa LED tse holim'a sefahleho li sebelisoa haholo lits'ebetsong tsa kantle le kahare ka lebaka la sebopeho sa tsona se tloaelehileng, masakaneng a tšepe a fetohang, le mefuta e fapaneng. Ebang ke ka ntle P13.33, P10, P8 le libaka tse ling, kapa ka tlung P1.875, P1.667, P1.53, P1.25 le lisebelisoa tse ling tse nyenyane tsa sebaka, lifaha tsa lebone tsa LED tse ka holimo li ka finyella litlhoko.
Litebello tsa nts'etsopele ea lifaha tsa lebone la lebone la pontšo ea LED li bonts'a mokhoa o motle. E tsamaisoa ke lintlha tse ngata tse kang tsoelo-pele ea thekenoloji, kholo ea tlhokahalo ea 'maraka le tšehetso ea leano, ts'ebetso ea lifaha tsa lebone la module e tla tsoela pele ho ntlafala mme sebaka sa kopo se tla tsoela pele ho atoloha. Nakong e tlang, re na le lebaka la ho lumela hore lifaha tsa lebone la lebone la pontšo ea LED li tla bapala karolo ea bohlokoa masimong a mangata le ho tlisetsa batho phihlelo e mebala-bala ea pono.
