Mokhoa oa ho etsa lesela la LED lapeng?

Ho bonolo ho etsa lesela la LED ka matsoho a hau, u nahanela likhetho tsa motho. Ho etsa sena, khetha lisebelisoa le lisebelisoa tse hlokahalang, ebe u latela litaelo tsa mohato ka mohato bakeng sa ho etsa le ho hokahanya sehlahisoa.

Lisebelisoa le lisebelisoa tse hlokahalang

Ho iketsetsa lesela la LED, o tla hloka sete e nepahetseng ea lisebelisoa le lisebelisoa. E ka fapana haeba ho na le lintho tse sieo kapa li ipapisitse le khetho ea motho. Nakong ea ts’ebetso ea tlhahiso, lisebelisoa tse latelang li tla hlokahala:

• Lithapa tsa textolite kapa getinaks . Foil textolite (seaparo se tenyetsehang se koahetsoeng ka koporo ea koporo) se tla thusa haholo mosebetsing. Haeba li-chips tsa LED (li-LED tsa LED) li sebelisoa, joale li ka rekisoa ka ho toba ho foil textolite, e tla thusa ho tlosa masoba a ho cheka le ho kopanya lithapo tse eketsehileng.
• Diode . Ho molemo hore motlakase o sebetsang oa li-LED o be ka tlase ho 3 volts. U ka sebelisa li-diode tse pota-potileng ka maoto kapa ka mokhoa oa li-chips ho latela theknoloji ea tlhahiso. Ka mohlala, li-LED tse pota-potileng – tse tšoeu tse pepeneneng 3014UWC, 5AW4QC, 10003UWC, ARL2-3214UWC (moetsi ARLIGHT); Li-diode tsa SMD – BL-LS3014A0S1UW2C (tse entsoeng ke Betlux Electronics), KA-3528PWC-A (tse entsoeng ke Kingbright). Palo eohle ea diode e angoa ke matla a motlakase (12, 24 V) le khetho ea khanya. Theipi ea mebala e mengata ea RGB e hloka li-diode tsa mebala e meraro (e khubelu, e putsoa, ​​​​e tala), ‘me ha u sebelisa li-diode tsa SMD, u ka sebelisa li-LED tsa RGB tsa mebala e meraro.
• Khanyetso (resistors) . Fokotsa palo ea hona joale e phallang ka li-LED. Ho hanyetsa ho hlokahalang ho baloa ho sebelisoa molao oa Ohm (R = U / I). U sebelisa mohlala, u ka inahanela palo ea khanyetso ea mohanyetsi ha diode tse tharo tsa 3 V le 20 mA li kopantsoe ka letoto ho tloha mohloling oa hona joale oa 12 V. Tabeng ena, ka kakaretso ea 9 V, moeli. ea 3 V e hlokahala, palo ea khanyetso e hlokahalang e etsoa ho sebelisoa mokhoa: 3 V e arotsoe ke 20 mA (0.02 A). Ka lebaka leo, ho hlokahala 150 ohm resistor.
• Lithapo tse nang le karolo efe kapa efe ea sefapano, empa ka ho khetheha li se ke tsa feta 0.35 square metres. mm . Ho sebelisa lithapo tse teteaneng le tse thata ho tla ba bonolo ho sebetsa ka tsona.
• Mocheso o fokotsa li-tubing . E etsa hore tepi e be ntle le ho feta mme e etsa mesebetsi e sireletsang.
• Meqathatso e entsoeng ka libotlolo tsa polasetiki kapa thepa e tšoanang . E sebelisoa ho fetola ‘mala o hlahisoang ke diode.
• Sealant kapa motsoako (resin) . Sebelisa haeba u hloka ho tiisa sets’oants’o sena ho etsa hore se se ke sa mamella mongobo o mosoeu.

Ha o etsa lesela la LED, o tla hloka lisebelisoa tse latelang:

• tšepe ea tšepe e nang le rosin le solder;
• drill kapa cutter (bakeng sa ho seha likhoele tsa getinax kapa textolite), o ka sebelisa lisekere tse tloaelehileng;
• screwdriver kapa drill e nang le li-drill tse tšesaane, empa u ka li nkela sebaka ka awl e tloaelehileng;
• ho haha ​​​​moriri o omisitsoeng kapa o bobebe o tloaelehileng oa ho futhumatsa mocheso o fokolang.

Ho hlahisa lihlahisoa tsa LED

Ho thata haholo ho kopitsa lesela la LED le entsoeng ka feme. Ena ke boto ea potoloho e hatisitsoeng e nang le setsi se feto-fetohang, moo diode tse nang le li-resistant SMD li kenngoa. Sebokeng sa lapeng, ho e-na le lisebelisoa tsena, u ka sebelisa seaparo sa textolite le li-LED tse bonolo. U lokela ho etsa se latelang:

1. Etsa mohopolo.
2. Ho ea ka motlakase o lekantsoeng le hona joale oa li-LED, li li kopanye ka lihlopha ka lihlopha tse nang le mochine o thibelang ho thibela hona joale.
3. Bakeng sa ho feto-fetoha ha tepi, hoa hlokahala ho beha textolite ka thoko ka lihlopha. U hloka feela ho tlohela lera ka holimo ka seaparo sa koporo.
4. Khaola lesela le bophara ba 6mm hore ho be bonolo ho lokisa li-chips tsa LED le ho kenya likhoele.
5. U sebelisa rula le pentšele, etsa matšoao ka likarolo tse peli tse lekanang tsa 3 mm.
6. Ka sehahi kapa drill, khaola sekhahla ho latela mola ho ea botebong ba lera la koporo ka bolelele bo felletseng. Hoa hlokahala ho sebelisa bolelele le bophara ba lihlopha, tse lekaneng ho amohela likarolo tsohle tsa potoloho ho tsona.
7. Pele u kopanya likarolo tse peli, ho hlokahala hore u koahele lesela ka flux.
8. Ka tšepe ea solder, o hloka ho koahela likarolo tse peli ka solder, empa u se ke ua lumella solder hore e phalle ho lebaleng le haufi. Lipineng tsena tse peli tse hlahisoang, li-chips tsa LED li tla beoa.
9. Solder li-chips tsa diode ka tšepe ea solder ka tsela e ts’oanang ho pina ka ‘ngoe. Hokela diode ka tatellano ka sebaka se lekanang ho tloha ho tse ling. Ha o etsa strip ea RGB, fetola mebala ea diode ha e ntse e lokisoa.
10. Ha o sebelisa lesela la LED la 3-12 V, ho tlameha ho sebelisoe lihanyetsi tse fokotsang. Li lokela ho behoa ka mahlakoreng, pakeng tsa diode, kapa ka morao ho latela maemo a sebaka.
11. Solder li-strips ho hokahanya lesela la diode.
12. Lithapo tsa solder.
13. Ho etsa hore sesebelisoa se shebahale se le botle haholo, beha litheipi tsa diode ka har’a tube e hlakileng ea ho fokotsa mocheso hammoho le lesela le sehiloeng ho tloha botlolong (bona ka lehlakoreng le ka morao).
14. Chesa tube ea ho fokotsa mocheso ka se omisang moriri ho hula likarolo tsohle hammoho.
15. Haeba u batla ho etsa sebopeho sa aquarium, joale se tlameha ho koaloa lipheletsong ka silicone sealant, e tla etsa hore sehlahisoa se se ke sa kena metsing.

Ho kenya le ho hokahanya

Ho kopanya lesela la LED ke mokhoa o bonolo. Ka motlakase o sebetsang oa sesebelisoa se entsoeng sa 12 V, o tla hloka
phepelo ea motlakase e fetolang mefuta ea 220 Volt sebakeng sa ho tsoa. Ntho ea bohlokoa ka ho fetisisa ke ho hlompha polarity. Ha o sebelisa motlakase o tloaelehileng, ka ho kenya letsoho o hloka ho bulela karolo le zero ho tloha sebakeng seo, ‘me ho tsoa – terata e khubelu “+”, e putsoa “-“. Haeba u batla ho laola boemo ba ‘mala, dimmer e hokahane pakeng tsa strip le mohloli oa matla (ho shebella polarity). Sebopeho se felileng se hlophisitsoe ka mekhoa e fapaneng:

• ho sebelisa li-clamps tsa polasetiki;
• mohaho o ka har’a tube ea ho fokotsa mocheso o khomaretsoe ka tepi e mahlakoreng a mabeli;
• leaky textolite strip e khomaretsoe ho li-screws kapa li-screws tse itšebetsang ka likoti tse phuntsoeng pele;
• sebelisa silicone sealant kapa lipekere tse metsi.

Haeba mocheso o fokotsang mocheso o sa sebelisoe ho kopanya tepi, ho lokela ho sebelisoa sekontiri se sa nke lehlakore.

U ka sebelisa profil e khethehileng ea aluminium, e tsitsitseng ka li-screws leboteng, ‘me tepi e se e khomaretsoe ho eona.
Profiles bakeng sa lihlopha tsa LEDli tlatsitsoe ke polasetiki ea li-diffuser e patang li-diode mme e kenya letsoho ho thehoeng ha khanya e ts’oanang haholoanyane. Baetsi ba kenya li-fan ka har’a lisebelisoa tse matla tsa matla, tse ka fetohang mohloli oa lerata ‘me li tla kena-kenana haholo. Boemong bo joalo, phepelo ea motlakase e tlosoa ka kamoreng e ‘ngoe moo e ke keng ea baka tšitiso. Sheba litaelo tse qaqileng tsa ho hokahanya le ho kenya lesela la LED ka matsoho a hau: https://www.youtube.com/watch?v=UKWm6RBg6wM Lesela la LED le iketselitseng le ka fetoha sebaka se felletseng sa sehlahisoa se felileng, ‘me ho tse ling. maemo a ka ba a molemo le ho feta. Ha o kenya lesela la LED, mehato ea ts’ireletso e tlameha ho hlokomeloa mme monyetla oa ho qhaqha ka mokhoa o sa fellang kapa o feletseng o lokela ho bonoa esale pele.
