Lub teeb yog lub teeb txawb hluav taws xob nqa tau. Lub tswb raug suav nrog lub teeb ci teeb tsa hauv lub teeb pom kev zoo, roj teeb, xov hlau thiab hloov. Qhov chaw ntawm lub teeb yog LED piv txwv li lub teeb emitting diode. Hauv LED cov ceg ntev dua yog qhov zoo kawg thiab ceg luv yog qhov tsis zoo kawg. Nws yog lub diode uas tso cai rau tam sim no ntws tsuas yog los ntawm qhov kawg mus rau qhov tsis zoo kawg. Lub cell qhuav hloov pauv khaws cov tshuaj muaj zog rau hauv hluav taws xob. Ob lossis ntau lub cell tsim lub roj teeb. Lub cell qhuav yog zinc carbon cell. Nws tsim hluav taws xob txog li 1.5 volt. Zinc thawv ua raws li cov hluav taws xob tsis zoo, cov pa roj carbon ua raws li cov hluav taws xob zoo. Lub electrolyte siv yog cov dej ntub dej ntawm ammonium chloride thiab zinc chloride. Nws yog tsim los ntawm lub tog raj kheej hlau Nws muaj cov ntaub ntawv tiaj tus thiab lub hau hlau nyob rau sab saum toj. Lub hau hlau yog qhov kawg ntawm lub xov tooj thiab lub hauv paus tiaj yog qhov tsis zoo ntawm tes. Qhov hloov yog lub tshuab hluav taws xob uas siv los ua lossis ua txhaum lub Circuit Court. cell, cov hluav taws xob ntau dhau tau tsim tawm ntawm qhov tsis zoo. Thaum lub cicuit raug kaw nrog txoj hauv kev, cov hluav taws xob muaj peev xwm taug kev mus rau qhov kawg. Yog li tig rov muab lub zog rau LED. Sab hauv LED lub tshuab hluav taws xob sib sau ua ke nrog lub qhov thiab lub zog raug tso tawm hauv daim ntawv ntawm lub teeb. Thaum qhov hloov pauv tsis ua haujlwm, lub Circuit Court tsis ua tiav thiab tam sim no tsis ntws los ntawm nws. Xws li Circuit Court hu ua qhib hluav taws xob. Thaum hloov pauv yog nyob rau ntawm txoj hauj lwm txoj kab hluav taws xob tau ua tiav thiab ntws tam sim no los ntawm nws. Xws li Circuit Court hu ua kaw kaw lus.

Ntxig cov cell hauv lub roj teeb. 2. Txuas qhov zoo (ntev dua ceg) ntawm LED nrog lub roj teeb zoo 3. Connect tsis zoo ntawm lub roj teeb nrog ib lub davhlau ya nyob twg ntawm kev hloov, lwm lub davhlau ya nyob twg ntawm kev hloov yuav tsum txuas nrog rau qhov tsis zoo (ceg me dua) ntawm LED raws li qhia. 4. Hloov ON mus kuaj yog tias nws ua haujlwm lossis tsis yog.
Kauj Ruam 3: Ua Lub Tog Raj Kheej Npog rau Lub Teeb
1. Txiav daim ntawv tuab A4 tuab hauv ib nrab2. Siv ib nrab los ua lub tog raj kheej zoo 3. Ua kom ntseeg tau tias txoj kab uas hla ntawm lub yob yuav tsum txaus kom haum rau lub roj teeb. 4A tus tswv vajvoog tuaj yeem siv los ua lub tog raj kheej raws li qhia
Kauj Ruam 4: Hloov Me Me Hauv Lub Tog Raj Kheej
1. Ua daim duab peb sab rau ntawm ob sab ntug ntawm lub tog raj kheej kom nws tuaj yeem glued kom npog nrog lub voj voos ntawm ib sab thiab tsom iav ntawm lwm sab. 2. Ua qhov yuav luag ze ntawm nruab nrab ntawm lub tog raj kheej thiaj li hloov tau ntxig rau ntawd.
Kauj Ruam 5: Ntxig Roj Teeb thiab Hloov
1. Txuas lub Circuit Court thiab tso roj teeb2.connect hloov raws li qhia. 3. Tshem tawm ob lub dav hlau sab nraum lub tog raj kheej kom LED tuaj yeem txuas nrog nws.
Kauj Ruam 6: Ua tus Reflector
Reflector sib sau ua ke thiab tsom mus rau lub teeb nyob rau hauv ib qho kev taw qhia Ua kom muaj lub teeb pom kev zoo, 1. Luaj cov ntawv txhuas rau ntawm ib daim ntawv thiab txiav lub voj voog loj ntawm kwv yees li 14cm txoj kab. 2. Ua ib qho hlais raws li qhia kom ua lub khob hliav qab.
Kauj Ruam 7: Ntxig LED
Txiav qhov taub ntawm lub khob hliav qab thiab ntxig LED
