A wuri na "haske kwan fitila Ilyich" zo zuwa ga haske LED

A mafi alamar tushen haske wadannan kwanaki, babu shakka, zama LED fitilu. Shin a high-tech zamani samfurin, LED haske a hankali zo domin maye gurbin gargajiya lagwanin, kazalika da daban-daban iri makamashi-ceton na'urorin, wanda a kasuwannin cikin gida na lighting maras motsi kasance ma mun gwada kwanan nan.

A kadan tarihi

Light watsi a lokacin da nassi na lantarki ta hanyar wani pn maha? Ar na wani semiconductor na'urar da aka sani tun farkon XX karni. Saboda haka, Henry Joseph akai-akai, da kirkiro na Birtaniya a 1907, da aka bayyana electroluminescence sakamako ta wucewa da lantarki ta hanyar wata biyu daga karfe - Karbid Kremniya, tare da rawaya, da kore da kuma orange haske a cathode. Similar gwaje-gwajen da aka za'ayi a shekarar 1923 ta Soviet masanin kimiyya Olegom Losevym (af, har ya zuwa farkon '70s da American masana kimiyya LED fitila yana da kyau mai suna - «Losev Light», daga baya da sunan da aka manta). Amma da gaske kome, idan wannan samu ba ba, sabili da haka ba diddigin ga dama da suka gabata.

A shekarar 1961, an jadadda mallaka firtsi ne infrared, kuma a shekarar 1962 - yi aiki a cikin haske (ja) kewayon da LED. Daga bisani, da sabuwar dabara aka ci gaba da inganta. Bi da bi, rage da kudin. Saboda haka, a shekarar 1968, a kan LED kwararan fitila, da farashin da aka game da $ 200, amma saboda su m amfani sosai iyaka.

Yau, wadannan fitilu suna amfani da kusan ko'ina. Don yin wannan, LEDs suna samuwa tare da dukan rare iri iyakoki: E27, E14, GU5.3, G53, GU10, G13.

A LED haske mafi fiye da saba?

LED fitilu bayar da wadannan abũbuwan amfãni:

• High luminous yadda ya dace. Modern misalai daga wadannan lighting maras motsi a cikin wannan siga ne m tare da karfe halide da sodium sallama fitilu.
• Low ikon amfani. Shi ne sau da yawa m fiye da na al'ada haske kafofin.
• Long sabis rayuwa. Dangane da manufacturer da fitilar fasahar LED iya wuce daga talatin zuwa dubu ɗari hours. Yawan a kan-kashe hawan keke, ba yawa tasiri a kan rayuwar LEDs.
• High ƙarfi kuma vibration. Wannan shi ne cimma saboda gaskiyar cewa babu kula inji danniya aka gyara.
• A low inertia. Ba kamar sauran fitilu, LED kusan nan da nan ta fara haskakawa a cika haske. Bayan haka, ta ba ji tsoron ikon surges.
• High muhalli friendliness. Ba kamar da makamashi-ceton fitilu, LEDs ba dauke da Mercury ko wasu abubuwa masu cutarwa.

Ba shi yiwuwa ba a ambaci cewa mafi kuma mafi motoci fara nema a kowace shekara LED hasken wuta ga mota. Samun wannan halaye kamar da LEDs ga iyali lighting, suna bayar da daban-daban embodiments na iyakoki (h1, h3, H7, h8, h10, da dai sauransu). Su suna shigar a kai da mota da fitilolin mota, kuma ba kawai a matsayin hazo, amma kuma kamar yadda low da kuma babban katako.

Zai yiwu ne kawai drawback, wanda yana da wani LED haske kwan fitila - babban kudin. Arha LED (LL) Kudinsa 500 rubles, da kuma farashin mafi tsada (tabo) zai iya isa 5000. Ko da yake duk, kamar yadda suka faɗa, shi ne zumunta. Babba sabis rai na LED fitilu, yawaita da yawan cinye wutar lantarki iya zama ma fi riba fiye da amfani na al'ada haske kwararan fitila.
