Nkhani za chikhalidwe ndi zachilengedwe
Popanga tchipisi ta LED, ma inorganic acid, oxidants, complexing agents, hydrogen peroxide, organic solvents ndi zinthu zina zoyeretsera zomwe zimagwiritsidwa ntchito popanga gawo lapansi, komanso gawo lachitsulo la organic gasi ndi mpweya wa ammonia womwe umagwiritsidwa ntchito pakukula kwa epitaxial, ndizowopsa. ndi kuipitsa. Izinso ndi zinthu zomwe zimagwiritsidwa ntchito popanga ma semiconductor ophatikizika ma circuits ndi mafakitale ena. Kwa makampani opanga zida za LED omwe ali m'gulu laukadaulo wapamwambawu, ukadaulo wawo wowongolera ndi njira zake ndizokhazikika komanso zogwira mtima, zomwe zimapangitsa kuti zikhale zosavuta kuchita chithandizo chopanda vuto.
Zida zowongolera za LED (zomwe zimadziwika kuti magetsi oyendetsa) sizosiyana ndi nyali zachikhalidwe za fulorosenti, nyali zachitsulo za halide, ndi ma ballast ena amagetsi, komanso kawopsedwe ndi zowononga zomwe zimapangidwa popanga zinthu zosiyanasiyana wamba zamagetsi.
Chipolopolo cha aluminiyamu chomwe chimagwiritsidwa ntchito kwambiri pa nyali za LED ndi chofanana ndi chipolopolo chamwambo cha aluminiyamu, ndipo kawopsedwe ndi zowononga zomwe zimapangidwa panthawi yopanga mapulasitiki kapena zipolopolo zachitsulo sizikuwonjezeka kwambiri.
Mwachidule, palibe chifukwa chodera nkhawa zinthu zowunikira za semiconductor zomwe anthu amakumana nazo mwachindunji, komanso zovuta zachilengedwe panthawi yopanga.

Zokhudza chitetezo chamunthu payekha
1. Magetsi otsika a LED ndi otetezeka kwambiri komanso amasocheretsa anthu
Ogwira ntchito zamaukadaulo ambiri m'mabizinesi ali ndi chidziwitso chozama komanso chosakwanira cha chitetezo chamagetsi pazowunikira zamagetsi za LED ndi magetsi oyendetsa, zomwe zimatsogolera kuchitetezo chamagetsi chazinthu zambiri zopangidwa ndi kupanga zowunikira za LED kudalira kwathunthu chitetezo chamagetsi oyendetsa. Komabe, kudzipatula kwamagetsi ndi kutchinjiriza kwa ambiri othandizira magetsi oyendetsa a LED sikukwaniritsa zofunikira. Kuphatikiza apo, kukwezedwa kwakukulu kokhudza chitetezo chamagetsi otsika a LED kumatha kusokeretsa anthu kuti azigwira pafupipafupi zinthuzo, zomwe zimapangitsa kuti pakhale chiwopsezo champhamvu chamagetsi kuposa zinthu zowunikira zachikhalidwe zomwe anthu samadziwa mosadziwa kuti voteji yawo ndi yowopsa ndipo amayesa kukhudza wamba. .
2. LED buluu kuwala ngozi vuto
Buluu chip mtundu woyera LED ili ndi sipekitiramu yomwe imakhala yokhazikika kwambiri pamagetsi owopsa kuposa nyali za fulorosenti, kuphatikizapo nyali zopulumutsa mphamvu, zomwe zimapangitsa kuti pakhale kuwala komwe kumakhala kovulaza kuwirikiza kawiri kuposa nyali za fulorosenti. Kuonjezera apo, malo otulutsa ndi ochepa ndipo kuwala kwake kumakhala kwakukulu, zomwe zimapangitsa kuti kuwala kwa buluu kuwonekere kwambiri kuposa nyali zina. Komabe, mwamalingaliro komanso kuyesa kwachitetezo chachitetezo cha nthawi yayitali, m'kuchita, zosakwana 5% za nyali zolimba kwambiri zapa desiki za LED zimapitilira zofunikira pa ngozi za RG1. Nyalizi zimangofunika kulembedwa ndi chizindikiro cha "Musayang'ane mwachindunji pa gwero la kuwala kwa nthawi yaitali" pamalo odziwika bwino ndikuwonetsa mtunda wotetezeka kuti akumbutse ogwiritsa ntchito kuti akwaniritse zofunikira zoyenera. Zitha kugulitsidwa ndi kugwiritsidwa ntchito popanda mavuto, zomwe zimakhala zotetezeka kwambiri kusiyana ndi kuyang'ana mwachindunji kuwala kwa dzuwa kwa nthawi yochepa. Ndipo powonjezera chivundikiro cha mchenga, magetsi a LED alibe mavuto. Ndipo si ma LED okha omwe amabweretsa vuto la biosafety. M'malo mwake, zowunikira zachikhalidwe, monga nyali zoyambirira zachitsulo za halide, zitha kukhala ndi zowopsa za UV komanso zowopsa za buluu.
3. Nkhani ya Strobe
Ziyenera kunenedwa kuti zowunikira za LED zitha kukhala zocheperako komanso zokhazikika pakutulutsa (monga zambiri zofananira ndi madalaivala amagetsi a DC pamsika). Ndipo zopangira zosapanga bwino zimathanso kuthwanima kwambiri (monga zomwe zilibe magetsi oyendetsa, pomwe gululi lamagetsi la AC limapereka mwachindunji ku chingwe cha LED kapena COB-LED), koma izi sizosiyana kwambiri ndi vuto la chubu chowongoka. nyali za fulorosenti ndi ballast inductive. Izi sizidalira gwero la kuwala kwa LED, koma pamagetsi ndi magetsi oyendetsa galimoto omwe amagwirizana nawo. Mfundo yomweyi imagwiranso ntchito pakuthwanima kwa zinthu zounikira zakale.
