Kodi Makhalidwe Anayi a Mikanda ya Nyali ya LED ndi Mikanda ya Nyali ya LED ndi Chiyani?

Kodi ukadaulo ndi mawonekedwe a ma diode owala ndi ati? Ukadaulo ndi mawonekedwe a ma diode owala: Diode yowala imatanthawuza kupanga ukadaulo wa LED (Light-Emitting Diode, Light Tube) ngati yayikulu. Ma diode a tsitsi ndi gawo lolimba la semi-superconductor. Coaxing yake DC ndi yosalala kwa semi-superconductor P-N malo omangira, ndiyeno zamagetsi za gulu ndi electron ya gulu la electron ndi carnitar ya gulu la carnitar zimagwirizanitsidwa. , Kuti apange ma photon emitters, diode yonyezimira ya mitundu yosiyana imatha kubweza kuwala kuchokera ku mzere wofiira wamkati kupita ku kuwala kwa buluu, kuchokera ku zofiirira - kuwala kupita ku mzere wofiirira. & nbsp Gundam mikanda ya nyali ya LED; nyali yowala yokhala ndi diode yowala ndi yaying'ono komanso yopepuka, ndipo imakutidwa ndi epoxy resin. Zitha kutenga mkulu -mphamvu makina mlandu ndi mantha. Maola 50,000-100,000, kuposa maola 1,000 a mababu amtundu wa tungsten ndi maola 10,000 a nyali ya fulorosenti. Chifukwa kugwiritsidwa ntchito kwa diode kungafikire zaka 5-10, osati phindu la m'malo mwa nyali likhoza kuwonjezeka, komanso makhalidwe omwe amatha kuyendetsedwa ndi mphamvu yapamwamba -DC imatha kuyendetsa chonyezimira. Mphamvu ndi theka chabe la fulorosenti nyali chubu, kotero kuwala diode komanso kugwirizana mphamvu za kupulumutsa mphamvu ndi kupulumutsa mphamvu. Poyerekeza ndi magwero ena chilengedwe kuwala pa chiyambi, tungsten filament thovu kuwala ndi za 15 LM/W, fulorosenti dzuwa za 45 60 LM/W, HID nyali za 120 150 LM/W. Iwo pang'onopang'ono anapeza kuipa; uku ndiko kuyerekezera kwa mphamvu zowunikira za diode yowunikira ndi nyali zina wamba: mawonekedwe a kuyatsa kwa diode kuyatsa kwa kuyatsa kowala kwa diode, gwero la kutentha kwa ma diode, zikhalidwe zogwirira ntchito, sing'anga-kakulidwe, zowopsa, zowunikira kwambiri. kuwala kwa dzuwa (fluorescence fluorescence Light) Kuunikira kwa fulorosenti yopulumutsa mphamvu, koma kuthetsa mavuto monga mercury ndi mercury purification, white thermal tungsten filament thovu ndizochepa, kugwiritsa ntchito mphamvu zambiri, moyo waufupi, ndi tsitsi losalimba ndi ma diode owala. Komabe, anthu omwe sagwiritsa ntchito diode pang'ono adzapeza kuti diode yowala imakhala yosalala makamaka chifukwa cha kusalala, komwe kumakhala kosavuta kutentha kwa kuvutika kwa kuwala, komwe kumapangitsa kuti tsitsi likhale lowala. Panthawiyo, ndiye kuti diode ya diode idapangitsa kuti isavutike ndi kutentha kwanthawi yayitali, ndipo moyo wake udzachepetsedwa. Nkhaniyi imachokera ku mikanda ya nyali ya LED.
