Simulated lub koob yees duab LED teeb
Qhov no yog lub koob yees duab simulation LED hmo ntuj teeb. Txhim kho cov neeg siv kev them nyiaj, hloov cov teeb meem roj teeb, siv cov hnub ci vaj huam sib luag cia khoom siv hluav taws xob. Nws cov duab ua raws li lub koob yees duab, uas muab kev nkag siab ntawm kev saib xyuas kev nyab xeeb, tab sis kuj coj kev yooj yim rau lub neej thaum hmo ntuj.

Solar vaj huam sib luag LED teeb
Photovoltaic panels hloov lub teeb lub zog rau hauv hluav taws xob thaum illuminated, uas yog khaws cia rau hauv cov roj teeb.
Nyob rau yav tav su, thaum lub hnub tsis ci txaus, photovoltaic panels tsim hluav taws xob tsawg,
Tsis siv neeg txhais tes hloov, txuas lub roj teeb Circuit Court los ua LED teeb.
