Thyristor LED. Features iyo mabda 'hawlgalka

LED Thyristor - taasi waa kale oo weyn oo si faahfaahsan jira maanta, kuwaasi oo loo isticmaalo soo saaridda ee qalabka iftiiminta. Faa'iidooyinka LED: socdeyba hawlgal, isticmaalka awood u hooseeya iyo cabbir yar.

Mabda'a hawlgalka ee LED ah

Sababta habka luminescence waa recombination ee godad wanaagsan eedeeyay iyo qayb xun oo lagu eedeeyay in zone ph-guurka ah. zone Tani waa interface laba qalabka (semiconductors) oo leh awood conductivity kala duwan ee hadda jira. In la abuuro uu yahey mid dhalaalaya oo qaab multilayer ee chip LED. Its dhalaalka waa la kordhin karaa by codsanaya xiisad xoog leh, laakiin qiimaha badan oo ah diode hadda ku dafiri karto. Nuurkii LED laga beddeli karaa jihada of hoos. Its dhismaha waa mid aad u fudud, laakiin waqti isku mid ah, soo saarayaasha ugu Uma sheegayno qarsoon oo wax soo saarka ee badeecada.

Si aad u taariikhda, tiristotny LED casri ah oo aad u soo saar leh, maxaa yeelay, safafka hufnaan ay ka 60 ilaa 70%. Haddii aan is barbar dhig ku laambad incandescent (oolnimada of taas oo kaliya 5-7%) la LED, ka khayr badan celceliska toban jeer dambe. Muddada hawlgalka sheegatey ee qalabka iftiiminta isticmaala thyristor diode light-emitting, waa toban sannadood iftiinka joogto ah. kaydka tamarta marka la isticmaalayo LED, sida LDR la barbar dhigo qiyaastii waa 50%, marka la barbar dhigo kula incandescent - 85%.

wax soo saarka The light of dioska- casri ah IPF iyo HPS (iyo DNaZ) tartami kari wayeen. tiradaasi le'eg yahay ilaa 150 lm / W. Muddada Dib u ah nalalka LED - 2-3 sano. Ka dibna, ku haray toban sano, waxaad badbaadin 85% ka mid ah korontada baabbi'iyey bil kasta.

Kokes. sifooyinka

LED, kaas oo sifooyin aan ahayn analogues liita, waxay leeyihiin faa'iidooyinka soo socda:

• soo saaridda ee uu Kokes waxaa loo isticmaalaa quraarad, oo sidaas daraaddeed laambad ifi noocan ah waxay leeyihiin cimri dherer sare, iska caabin gariirka iyo isku halaynta;
• LED adkaysi u isbedbedelka danab oo ha baabbi'iyo kaliya 0.4-0.6 A;
• Thyristor LED hawl wax ku ool ah in xaalad aad u adag, xataa marka heerkulku aad u yar yahay.

Si aad u bilowdo LED ah, waxay u baahan tahay qaali buundada diode, taasoo keenta qiimaha nalalka hore ahayd arrin duldhigay. Soo-saareyaasha xalliyo dhibaatada this. Jaantuska Schematic ayaa la bedelay iyo halkii dimmers triac thyristor ayaa codsatay. Natiijada waxa ay aheyd qalab ka kooban laba thyristors ku xiran ee isku midka ah, waxay ka dhigan tahay miiska. Sababo la hal-abuurnimo this, baahida loo qabo in buundada diode a maqan yahay maanta. Go'aanka Tani waxay keentay in ay alaabta jaban oo aad u kordhay heerka ammaanka iyo tayada alaabta ku salaysan thyristors ah.

Thyristor LED waxaa si balaadhan looga isticmaalaa in soo saaridda ee qalabka iftiiminta. Nolosha adeeg dheer Its, isku halaynta iyo farsamaynta ku farxi macaamiisha, sida chandeliers iyo aaladaha kale ee la LED-Nuur ma aha oo kaliya dhaqaale, laakiin sidoo kale fiirin mid aad u qurux badan.
