Khetho ea li-LED e lokela ho hlahlojoa ka mokhoa o khutsitseng le ka saense, 'me mehloli ea mabone le mabone a theko e boima ka ho fetisisa e lokela ho khethoa. Se latelang se hlalosa ts'ebetso ea mantlha ea li-LED tse 'maloa:

1. KhanyaKhanya ea LEDe fapane, theko e fapane. Mabone a LED a sebelisoang bakeng sa mabone a LED a tla kopana le maemo a sehlopha sa I sa laser grade.

2. LED e nang le matla a matla a antistatic e na le nako e telele ea tšebeletso le theko e phahameng. Ka kakaretso, matla a matla a antistatic a fetang 700V a ka sebelisoa bakeng saLebone la LED.

3. Lebone la LED le nang le leqhubu le tšoanang le na le 'mala o tšoanang. Haeba 'mala o hlokahala hore o tšoane, theko e phahame. Ho thata ho baetsi ba se nang led spectrophotometer ho hlahisa lihlahisoa tse nang le 'mala o hloekileng.

4. Leakage jwale LED ke tsela e le 'ngoe conductive luminous' mele. Haeba ho na le reverse current, e bitsoa leakage. Led le leakage e kholo ea hona joale e na le bophelo bo khuts'oane ba ts'ebeletso le theko e tlase.

5. Lehlakore le khanyang la li-LED tse nang le lisebelisoa tse fapaneng li fapane. Sekhutlo se khethehileng sa khanya, theko e phahameng. Joalo ka li-angle tse felletseng tsa diffusion, theko e holimo.

6. Senotlolo sa boleng bo fapaneng ba bophelo ke bophelo, bo khetholloang ke ho bola ha leseli. Ho fokotsa leseli le lenyenyane, bophelo bo bolelele ba tšebeletso, bophelo bo bolelele ba tšebeletso le theko e phahameng.

7. Thee ntšang khanya'mele oa chip LED ke chip. Theko e fapana haholo ka li-chips tse fapaneng. Li-chips tse tsoang Japane le United States li theko e boima haholo. Ka kakaretso, litheko tsa li-chips tse tsoang Taiwan le China li tlase ho feta tse tsoang Japane le United States.

8. Boholo ba chip boholo ba chip bo bontšoa ke bolelele ba lehlakore. Boleng ba chip e kholo ea LED bo molemo ho feta ba chip e nyane. Theko e lekana ka kotloloho le boholo ba sephaphatha.

9. Colloid ea colloid ea LED e tloaelehileng hangata ke epoxy resin. LED e nang le anti ultraviolet le e thibelang mollo e theko e boima haholo. Lebone la boleng bo holimo la kantle la LED le lokela ho ba khahlanong le ultraviolet le ho se kenelle mollong. Sehlahisoa se seng le se seng se tla ba le meralo e fapaneng. Meetso e fapaneng e loketse merero e fapaneng. Moralo o ts'epahalang oa mabone a LED o kenyelletsa: polokeho ea motlakase, polokeho ea mollo, polokeho ea tikoloho e sebetsang, polokeho ea mochini, polokeho ea bophelo bo botle, nako ea ts'ebeliso e bolokehileng le lintlha tse ling. Ho latela pono ea polokeho ea motlakase, e tla ipapisa le litekanyetso tse amehang tsa machaba le tsa naha.
