Na u kile ua kopana le mathata a mangata a sa utloisiseng, 'me mathata a tloaelehileng ke afe? Hobaneng ha diode e ntšang khanya e ke ke ea ba le matla a maholo kapa overcurrent e sebelisa lebone le lesoeu la LED? Ka mantsoe a bonolo feela, e hlalosoa ke khanya e sebelisoang haholo ea 5mm e tšoeu ea LED. Matla a eona a tloaelehileng a ho sebetsa hangata a ka har'a 3.0-3.5V, 'me nako e tloaelehileng ea ho sebetsa ke 20mA 20mA. Leha ho le joalo, batho ba bangata ba nahana ka phoso hore tšebeliso ea li-LED tse khanyang tse nang le matla a ho feta-voltage kapa overcurrent li tla khanya haholoanyane, 'me sephetho sa sebele sa teko ke hore ka mor'a 15mA, phallo ea optical e eketseha haholo. Ka mor'a 20mA, ho batla ho se na pono-ho feta. Empa ho na le feberu e hlakileng. Hape ho na le teko ea bophelo: 20mA e sebelitse khoeli, 'me ho fokotseha ke 5% feela. Hona joale ho na le 95% optical flux. Ha 30mA e sebetsa ho fihlela matsatsi a 19, molumo oa leseli ke 50% feela. Ho ka nkoa hore lebone le lesoeu la LED le ka sebetsang lihora tse 100 000 tlas'a maemo a tloaelehileng le sebelisoa maqhubu a maholo, le nako ea bophelo ea lihora tse 600 feela! Li-LED li ka sebelisoa lihora tse fetang 50,000 ka litlhaloso tse akaretsang, 'me bahlahisi ba bang ba bolela hore LED ea eona e ka sebetsa lihora tse ka bang 100,000, empa sena ha se tiise hore lihlahisoa tsa LED li ka sebelisoa nako e telele. Ts'ebetso e fosahetseng le ts'ebetso e ka ba bonolo
“Senya
”Li-LED, li-LED li tla senyeha butle-butle ha nako e ntse e ea. Likhakanyo tse ling li bontša hore li-LED tsa boleng bo holimo li ka boloka ho feta 60% ea khanya ea pele ea khanya ka mor'a lihora tse 50,000 tsa ts'ebetso e tsoelang pele. Ho lelefatsa bophelo ba LED, hoa hlokahala ho fokotsa kapa ho tlosa ka ho feletseng matla a mocheso a hlahisoang ke chip ea LED. Matla a futhumatsang ke lona lebaka le ka sehloohong le etsang hore LED e khaotse ho sebetsa. Sena se hlalositsoe bakeng sa tšebeliso ea li-diode tse hlahisang leseli. Ho fumana lintlha tse ling, ka kopo ikopanye le tlhahlobo ea litšebeletso tsa bareki inthaneteng.
