Nws yooj yim rau kev khiav lag luam LEDs thaum lub hwj chim txuas nrog lub hauv paus. Hauv 99.9% ntawm cov xwm txheej, hluav taws xob yog "ntawm tes". Txawm li cas los xij, hauv cov chaw uas tsis txuas nrog lossis nyob deb ntawm lub hauv paus, cov roj teeb uas siv hluav taws xob LED strips tseem xav tau.

Peculiarities

3-volt LEDs txuas nrog ib zaug yuav xav tau ntau yam khoom siv.

Ntawm 1-1, 5 volts - circuits ntawm ib lossis ntau lub transistors rau "voltage boost "yog li los ntawm qhov hluav taws xob no (ib lub roj teeb nickel) cov cuab yeej ua rau 3.2 volts, yam tsis muaj LED yuav tsis ci. Rau qhov tsis tshua muaj LEDs ua haujlwm los ntawm 1.5 volts, tsis muaj qhov xav tau ntawm lub Circuit Court.

Yog tias muaj cov roj teeb kua qaub uas ua rau 1, 8-2, 3 V - tsis muaj qhov xav tau ntxiv rau qhov liab, xiav, daj thiab ntsuab LEDs.

Lawv ua haujlwm ntawm qhov ntsuas hluav taws xob tsawg ntawm 1, 8-2, 2 V, lawv tuaj yeem txuas ncaj qha, ua ke, hauv ib qho twg. Qhov ntau, qhov muaj peev xwm ntau nws yuav tsum yog.

Yog tias siv lub roj teeb lithium-ion, cov xim LED tau txuas nrog ua ke ua khub . Ntawm qhov siab tshaj plaws ntawm 4.2 V, lawv qhov ci ci yuav mus txog qib qis dua qhov nruab nrab (2.1 V rau LED). Cov khub no tau txuas nrog ua ke ib leeg. Tsis txhob sim txuas ib qho xim LEDs ua ke yam tsis muaj kev sib txuas ua ke - lawv yuav hlawv tam sim ntawd.

Muaj lub hwj chim los ntawm txhais tes, piv txwv li, lub roj teeb sab nraud nrog lub 5 V smartphone, tsis muaj xim lossis dawb LEDs tuaj yeem txuas ncaj qha: lawv yuav hlawv tam sim ntawd . Ntawm no koj xav tau kev tswj hwm DC qhov hloov hluav taws xob - cov no tau ntaus hauv Suav teb los ntawm ntau lab ib xyoos. Nws yog qhov yooj yim los xaj qhov xav tau thiab teeb tsa cov tswv yim thiab cov hluav taws xob siv lub tshuab ntsuas. Qhov tsis zoo ntawm DC hloov pauv hluav taws xob yog qhov ua tau zoo tsawg: poob tuaj yeem nce txog 34%, nyob ntawm qhov nkag thiab qhov hluav taws xob tso tawm.

12-volt pawg yuav tsis xav tau ib qho, tab sis ntau lub roj teeb. Rau 3 lub roj teeb lithium -ion, qhov ntsuas hluav taws xob yog los ntawm 9 txog 12.6 V - pawg yuav tsis ua haujlwm ntau dua yog tias koj qhib tsis yog 3, tab sis 4 LEDs hauv koob (kev khiav hauj lwm voltage tsis tshaj 12, 8 V). Kev lag luam muaj kev sib sau ua lag luam, hmoov tsis zoo, txawm hais tias muaj tam sim no-txwv cov neeg tawm tsam hauv txhua pawg, muaj raws nraim peb, tsis yog plaub LEDs. Ntawm no, muaj qhov ua txhaum ntawm qhov raug ntawm kev suav rau lub hom phiaj ntawm kev lag luam: tsawg dua LEDs tau siv, tab sis lawv hlawv sai sai, uas yuam cov neeg siv khoom hloov lawv tas li. Hauv cov xim liab, piv txwv li, rau sab nraub qaum (lub teeb nres), nws yuav raug dua txhawm rau txuas ncaj qha 6 LEDs rau 12 V (qhov sib dhos hluav taws xob yuav yog 13.2 V). Tab sis kev khaws nyiaj thiab lub siab xav tau yooj yim super-profit yuam cov tuam txhab tsim khoom kom nrhiav tsis tau 6, tab sis 5 LEDs rau txhua pawg. Thaum raug rau qhov hluav taws xob los ntawm lub roj teeb rov ua dua tshiab, LEDs ua kom sov thiab hlawv tawm ua ntej.

Rau 24-volt kab xev, qhov ntsuas hluav taws xob saum toj no yog ob npaug.

Xaus: kom tsis txhob ua kom cov LEDs ntau dhau, suav qhov ntsuas qhov ntsuas kom zoo . Cov dawb LED kub hnyiab tawm ntawm qhov hluav taws xob siab dua 3.2 V, liab - ntawm tus nqi siab dua 2, 2. Nws yog qhov yooj yim los laij cov roj teeb npib tsib xee lossis lithium - qee qhov muab 1-1, 5 V, qhov thib ob - 3- 4, 2. Sim suav cov phiaj xwm kom tsuas yog ib lub roj teeb ntawm tes (ib qho "txhab nyiaj") ua haujlwm: ob lossis ntau dua hnav ib txwm tsis xwm yeem, thiab hla dhau tshwm sim vim tsis siv lawv cov peev txheej kom puv.

Thaum twg lawv xav tau?

Ib qho LEDs thiab cov teeb pom kev (raws li ib feem ntawm lub teeb ci) xav tau hauv ob peb kis

1. Teeb pom kev zoo nyob rau qhov chaw uas thaiv tsis zoo, lossis, piv txwv li, hauv lub tebchaws lub tsev uas tsis muaj lub zog siv (lossis nws raug txiav tawm ntev uas tsis them nyiaj).

2. Teeb pom kev ntawm qhov chaw uas tsis muaj sijhawm los txuas rau tsev neeg lossis cov khoom siv hluav taws xob. Ib qho teeb meem tshwm sim yog teeb pom kev zoo ntawm lub tsheb kauj vab, hluav taws xob scooter lossis hluav taws xob scooter, lub tsev pheeb suab ntaub.
3. Hauv cov xwm txheej qhov kev tsim tshwj xeeb tsis xav kom puas los ntawm cov thaiv, tsis muaj txoj hauv kev los zais nws ua ke nrog lub zog siv.
4. Thaum ua haujlwm hauv ib qho chaw uas thaj chaw ntawm chav tsis tseem ceeb, thiab yog li ntawd, lub zog. Muaj lub teeb nyob qhov twg koj nyob qhov twg, koj mus qhov twg - lub taub hau (lossis tsom teeb) yog qhov kev daws teeb meem zoo tshaj plaws rau cov pawg kab. Nws yuav ci ntsa iab nkaus ntawm koj ib sab thaum xav tau. Qhov no ua rau nws muaj peev xwm txuag tau ntawm cov teeb pom kev zoo thiab cov kab hluav taws xob sib txuas sib txuas, teeb pom kev zoo ntawm qhov chaw uas tsis tsim nyog kiag tam sim no.

Qhov tsis zoo ntawm cov tshuaj no yog qhov tsis muaj peev xwm siv lub teeb ci ntawm lub roj teeb ntawm qhov siab, piv txwv li, kho kom zoo nkauj hauv chav ua noj hauv qab qab nthab, uas tuaj yeem ua kom pom kev zoo.

Qhov tsis zoo no tuaj yeem hloov pauv tau yooj yim ntxiv nrog kev pab ntawm cov hnub ci ci uas them lub roj teeb built-in thaum nruab hnub.

Nrog rau qhov pib ntawm tsaus ntuj, photodiode lossis photoresistor, uas yog ib feem ntawm lub teeb pom kev ib puag ncig, tig nws tus kheej ntawm lub teeb pom kev zoo . Lub zog tau sau hauv lub roj teeb tag nrho cov sij hawm nruab hnub nrig yog siv rau qhov ci ntawm cov teeb-pawg LEDs. Cov kab xev thauj mus los tsis tas yuav ua tus kheej -nplaum - lawv siv cov txheej tiv thaiv sab nrauv ua los ntawm cov yas lossis silicone.

Yuav ua li cas txuas?

Kev txuas LEDs nrog koj tus kheej txhais tes tau ua tiav raws li cov txheej txheem yooj yim tshaj plaws - roj teeb, hloov thiab teeb tsa LED. Nyias, rau rov them lub roj teeb, siv lub davhlau ya nyob twg ntxiv (lossis txuas), uas tuaj yeem nqa tawm los txuas rau lub adapter them.

Tag nrho cov qauv tau muab tso rau hauv rooj plaub me me nrog lub diffuser (lossis, sib tham, nrog lub lens tsom mus rau lub teeb ci). Saib xyuas qhov sib txawv ntawm daim kab xev lub teeb thiab lub zog siv: daim kab xev txuas "rov qab" yuav tsis ci - nws tsis hloov pauv, tab sis ncaj qha tam sim no, ib txwm dhau mus hauv ib qho kev taw qhia.

Hauv qhov chaw ntub, txuas cov kab xev ntawm chav dej tsis muaj dej IP-68: nws cov khoom siv hluav taws xob thiab cov khoom siv lub teeb yuav tsis poob qis hauv qhov cuam tshuam ntawm kev ntub dej.

Txawm hais tias qhov ntsuas hluav taws xob txog 12 volts raug suav hais tias tsis muaj teeb meem txawm tias rau tes ntub (yog tias daim tawv nqaij tsis puas), tag nrho cov qauv (Circuit) yuav tsum muaj kev tiv thaiv kom ntseeg tau los ntawm cov dej noo thiab txaws dej . Yog tias tsis muaj cov teeb pom kev zoo ua ntej nrog kev tiv thaiv noo noo, sau cov neeg sib sau ua ke nrog cov kua nplaum kub lossis roj hmab foob. Tsis txhob siv epoxy yog tias lub rooj sib dhos yog nyias heev - ib qho tawg thiab cov kab hluav taws xob tuaj yeem tawg. Cov cuab yeej "nrum" nrog epoxy tsis tuaj yeem kho tau.

Nws tsis pom zoo kom siv cov xim LED nyob hauv qhov chaw ntawm kev ua haujlwm tseem ceeb . Qhov tseeb yog tias liab, piv txwv li, yuav cuam tshuam cov xim ntawm cov khoom xiav thiab ntsuab hauv ib nrab qhov tsaus ntuj, hla lawv li dub lossis xim av. Ib yam li, cov khoom liab yuav tshwm rau xim liab dua li lawv, thaum tsis sawv tawm tsam tom qab, piv txwv li, ntawm cov neeg dawb, tseem muaj xim nrog lub ntsej muag liab liab nyob hauv cov xim zoo ib yam. Cov kev txwv zoo sib xws siv rau cov xim daj, ntsuab thiab xiav: cov khoom thiab cov khoom ntawm tib xim yuav ploj mus.

Cov xim uas tsim nyog tshaj plaws rau siv txhua hnub yog daj . Yog li, hauv cov tsom iav daj, lub teeb no siv tau tsis tso tawm, uas ua rau muaj kev tiv thaiv tsis pom kev zoo rau lub teeb lossis kab xev.

Nws tuaj yeem tau txais los ntawm kev qhib lub liab thiab ntsuab LEDs nyob rau tib lub sijhawm - teeb pom kev nrog cov xim daj -txiv kab ntxwv tau tsim, uas muaj kev nyab xeeb rau lub qhov muag.

Liab, ntsuab thiab xiav LEDs tuaj yeem siv tib lub sijhawm yog tias tsis muaj ib qho dawb . Qhov tseeb yog qhov sib txawv ntawm lub teeb yuav tsim teeb pom kev zoo, nco txog "sov", "nruab nrab" lossis "txias" dawb lub teeb ci.

Rau cov hlua LED tswj los ntawm cov cuab yeej siv wireless, cov khoom siv hauv qab no yuav tsum tau ua:

• kev tswj chaw taws teeb - qhov chaw hluav taws xob infrared;
• chaw nres nkoj - tus txais ntawm tib lub duab hluav taws xob infrared;
• chav sib txuas lossis tus yuam sij ntawm transistor - lub zog hloov khoom siv;
• qhov yooj yim microcontroller - tswj kev ua haujlwm ntawm tus yuam sij hloov.

Cov chaw taws teeb nws tus kheej yuav xav tau roj teeb cais. Cov phiaj xwm zoo sib xws tau pom daim ntawv thov hauv chav tsev, thaum lub zog hluav taws xob nruab nrab raug kaw ib ntus.

Yuav ua li cas zog?

Los laij cov kab hluav taws xob lossis lub luminaire uas tuaj yeem ua haujlwm nyob rau hauv yuav luag teeb pom kev zoo rau ntau dua ib xyoos, siv cov yam ntxwv ntawm LEDs, roj teeb thiab txwv kev tiv thaiv (lossis txo qis qhov hluav taws xob ntawm diodes), DC hloov pauv (hloov pauv, piv txwv li, 1, 5V-3V), nthuav tawm siab dua. Koj txoj haujlwm yog txhawm rau tswj hwm lub hwj chim kom ntau li ntau tau kom cov LEDs ua haujlwm rau lub sijhawm teev tseg los ntawm 25 txog 50 txhiab teev, raws li qhia hauv kev tshaj tawm . Kev ua haujlwm hnyav yuav ua rau lub teeb ci qis lossis ua rau lawv qhov kub hnyiab ntxov vim yog lub teeb ci ntsa iab.

Thaum muab cov kab hluav taws xob tso rau teeb pom kev sab hauv tsev yam tsis muaj lub qhov hluav taws xob, nws yog qhov zoo dua los siv cov roj teeb uas rov them tau . Tsis yog ib tus neeg siv niaj hnub no hauv lawv lub siab zoo, muaj tsawg kawg qee lub tswv yim txog roj teeb, yuav cov roj teeb uas siv tas mus li thiab ntau yam khoom siv ua haujlwm, txawm hais tias nws yog ib qho LED hauv lub teeb nyem me me.

Cov roj teeb muaj ntau ntawm cov khoom siv thiab lub moos phab ntsa, qhov twg kev siv hluav taws xob tsis zoo (ntsuas hauv microamps ib teev) uas nws tsis tuaj yeem siv lawv los ua qhov tseem ceeb tam sim no uas muaj kev siv tau zoo.

Txawm li cas los xij, tsuas yog cov roj teeb tsawg uas tsim nyog rau txoj kev - piv txwv li, cov roj teeb npib tsib xee -cadmium, them txawm tias qhov kub tsis zoo, uas ua rau lawv tsis tuaj yeem nyob hauv Far North.

Sim ua kom cov xov hlau luv li sai tau . Qhov no yuav cawm koj ntawm qhov tsis tsim nyog poob tam sim no hauv lawv. Lub teeb ci, uas tuaj yeem tso rau hauv ib qho chaw uas tsis muaj neeg nyob, yuav tsum nyob ze ib puag ncig cov roj teeb. Yog tias ib rooj plaub siv rau daim kab xev, tom qab ntawd nws raug nquahu kom tso lub roj teeb rau hauv nws, hloov nws tus kheej thiab lub dav hlau rau rov ua dua lub cuab yeej zoo li no. Qee tus kws tshaj lij tso lub roj teeb rov tau, piv txwv li, hauv ib da dej nrog lub taub loj dua, muab tso rau hauv txheej tiv thaiv ntawm daim kab xev tiv thaiv dej - los ntawm ib qho ntawm qhov kawg uas muaj qhov txuas rau txuas.
