ʻoaka o LEDs: inoa, hōʻikeʻano

Pinepine i ka waihona waiwai kuai Radio wahi, e ike hiki keʻano LEDs. Ka mea, uaʻokoʻa ma ka ikaika a me ka waihoʻoluʻu glow. ʻoaka o LEDs (MSD) i hoʻokū pono ia me ka mea uholo uila hehee wale integral pāpaʻa nā mīkini uila nona ka alapine (frequency) o 1,5-3Gts outbreaks.

He nui aeoaeuneiai Radio ana noonoo i kēia mau manaʻo ua lapuwale a me ka mea e e auou caiaiai me ho'ēmi LED nā hoailona. Paha, ma kekahiʻaoʻao, he pololei lakou. Naʻe, i ka DPA kekahi i ka pono e nei. E ho'āʻo i ka maopopo mea mau i ka pono o ia huahana.

ʻoaka o LEDs, ma ka mea, o ka piha ooieoeiiaeuiiai pa alima nona ka papa kuhikuhiE manao - e,ʻo lohe, ia mea he hana o ka malamalama-ka hōʻikeʻana. Ua E hoi e hoʻomaopopo i ka nui o kaʻoaka o mea uholo uila hehee wale mai i oko mai o ka maʻamau anakahi LEDs. Eia naʻe, hoʻowahāwahā kona olelo hoopomaikai nui, ma ka MSD nā mea uholo uila inoaia oscillators, e like me kekahi mau oihana mua. Inā i ka lāʻau ikiʻai wale mīkini hana wāwahie ua papahana iʻike mau Radio eiiiiiaiou, keia manao aole loaa ia oukou he 'ano respectable nui. Ua mea waiwai 'ana i kumumanaʻo i kaʻoaka o LEDs i loa paʻa. Anakahi uila kokuaia mai e na oihana mua o loko o ka laulā 1,8-5 V no ka haahaa anakahi uila manaʻo a me 3-14 V no ke anakahi uila kiʻekiʻe. Ka Hawaii photo ma lalo hōʻike he blinking alakaʻi 12 volts.

Pono MSD:

- he ākea huahelu o ka lako hou voltages (14 volts);

- uuku nohona ma Ana ;

- muli o kona kulana he olelo hoopomaikai kukui-ka hōʻikeʻana lima kūlana kiʻekiʻe;

- kekahi ea puka komo'ōniʻoniʻo nona. Kekahi Lolina o keʻano LEDs i mau kukulu-ma ke ano diodes me ka loli iki ana alapine (frequency) o flares (huali, yellow alakaʻi ma luna o ka Hawaii photo hōʻike);

- i ke ano o MSD ua hoaponoia ma ka mea uuku manaʻo, ma i ka ikaika e pono ai i ka nui o nā eiiiiiaiou a me ka mana hokii. Mau diodes, ma muli o ia kona lolouila kaapuni akoakoa ma ka MOS hale i ka haʻahaʻaʻikena hokii mea ma ka i lawa ke kiekie ea puka mana;

- a ua lalapa mea uholo uila mea hiki e puku i ka ooieoeiiaeuiiai pa alima.

Ma ka huakai kaapuni mau kiʻikuhi i MSD Kimia kiʻi mea okoa mai kaʻike mau LED pono dotted laina pua nô huali, hehee ai ka waiwai.

E ka noʻonoʻo i hou au mamuli o ka manao o keʻano LEDs. Ma ka aniani moakaka hale hehee ai hiki ke ike, i mea constructive diode he o nā māhele. Light K'lauea? Inoaia ua kau ma luna o ke kumu o ka cathode (io)'ūholo uila, a me ka? Inoaia-mīkini hana wāwahie ua ma muli o ka anode (maikaʻi'ūholo uila). Nā māhele o ka mea i pili i ekolu gula na alahaka. Inoaia mīkini hana wāwahie mea he kiʻekiʻe alapine (frequency) haku oscillator i hana noke, kona alapine (frequency) ka puni 100 kHz. ¶ A i loko o noaia huali, diode mahele waiwai i keia wa, i akoakoa ma Logical hehee wale. Ka mea, i hookaawale ai i ka mea kiʻekiʻe alapine waiwai io i ke kiʻekiʻe o ka 1.5-3 Hz. Oe i noi mai ai. "Akā, no ke aha la ke hoʻohana i ke kiʻekiʻe-alapine (frequency) mīkini hana wāwahie me ka mahele waiwai, no ke aha la ka mea, ua hiki ole i ka hoʻohana 'ana i kekahi haʻahaʻa-alapine (frequency) oscillator, a pela Nohie i ka manao?" O ke kumu ho i ka mea ia ia no ka hoʻokō 'ana i ka mīkini hana wāwahie o ka hana' pono he nui capacitance mea pihana no vremyaopredelyayuschey kaula. E hoʻokō e like me ka mea pihana e noi aku i ka nui nui wahi ma mua ma ka hoʻohana 'ana o ke kiʻekiʻe-alapine (frequency) mīkini hana wāwahie.

A nānā mākou i ka ua i ka a ua lalapa alakaʻi. A ma luna o ka ninau o i mea maikaʻi - a me nā loina 'enehana MSD anakahi diodes e pane i hoʻowahāwahā i ka cheapness o ka lua,ʻoaka o diodes i loaʻa lākou laulā a me ka mai ole paʻi i ka mea kahiko.
