Flashing LEDs: los, hauj lwm

Feem ntau cov khw muag khoom noj muag cov xov tooj cua chaw, yuav pom teeb ntsais LEDs. Lawv yog cov sib txawv nyob rau hauv lub dag lub zog thiab xim ci ntsa iab. Flashing LEDs (MSD) yog ntsuas nrog semiconductor ntsiab ib mem tes generators uas nws zaus yog 1,5-3Gts kab mob.

Muaj ntau pib xyaum ua xov tooj cua tswv xav txog hais tias cov pab kiag li lawm yog puas thiab lawv yuav tsum tau hloov nrog cheaper LED ntsuas. Tej zaum, nyob rau hauv ib co txoj kev lawv yog txoj cai. Txawm li cas los, lub DPA kuj muaj cai nyob ua ib ke. Sim kom to taub txog dab tsi yog qhov zoo ntawm tej khoom.

Flashing LEDs, nyob rau hauv qhov tseeb, yog ib tug ua tiav kev haumxeeb chav tsev uas nws lub ntsiab lub hom phiaj - nyiam xim, nws yog ib tug muaj nuj nqi ntawm lub teeb-signaling. Nws yuav tsum tau muab sau tseg tias qhov luaj li cas ntawm cov flashing semiconductor ntsiab tsis txawv los ntawm tus txheej txheem qhia LEDs. Txawm li cas los, txawm nws muaj kev cog lus ntawm loj, nyob rau hauv lub MSD muaj xws li semiconductor nti oscillators, raws li zoo li ib co ntxiv hais. Yog hais tias tus mem tes generator yog tsim nyob rau hauv cov pa xov tooj cua Cheebtsam, qhov no tsim yuav tau muaj ib tug ncaj respectable loj. Nws yog ib nqi sau cia hais tias lub flashing LEDs yog heev universal. Voltage mov ntawm tej lub ntsiab yog nyob rau hauv ntau 1,8-5 V rau cov uas tsis voltage pab kiag li lawm thiab 3-14 V rau lub high voltage. Lub yees duab hauv qab no qhia tau hais tias ib tug blinking LED 12 volts.

Zoo MSD:

- ib tug ntau yam ntawm mov voltages (14 volts);

- me me zuag qhia tag nrho qhov ntev ;

- ib tug heev compact teeb-taw ntaus ntawv;

- sib txawv emission xim. Ib txhia variants ntawm flashing LEDs muaj ob peb ua-nyob rau hauv cov xim diodes uas ua zaus ntawm flares (flashing daj LED ntawm tus yees duab qhia);

- kev siv cov MSD yog tsis txhaum nyob rau hauv me me kiag li lawm, nyob rau hauv uas cov nruj uas yuav tsum tau mus rau lub luaj li cas ntawm Cheebtsam thiab zog noj. Cov diodes, vim nws cov hluav taws xob Circuit Court tuaj txoos ua ke nyob rau hauv lub hlis lug muaj ib tug uas tsis muaj tam sim no noj yog ib tug txaus siab emission hwj chim;

- Flashing semiconductor ntaus ntawv muaj peev xwm txawm yuav hloov tau cov kev haumxeeb chav tsev.

Nyob rau hauv lub Circuit Court kos duab MSD duab duab yog txawv los ntawm cov pa LED cia li dotted kab sub symbolize flashing lub caij khoom.

Cia peb xav txog nyob rau hauv ntau yam tus tsim ntawm flashing LEDs. Los ntawm cov pob tshab tsev nyob lub caij yuav pom, uas yog constructive diode muaj ob qhov chaw. Lub teeb emitting nti yog muab tso rau hauv lub hauv paus ntawm lub cathode (tsis zoo) electrode thiab lub nti-generator yog raws li nyob rau hauv lub anode (zoo electrode). Tag nrho cov qhov chaw hauv lub ntaus ntawv yog kev cob cog rua nrog peb kub choj. Nti generator yog ib tug high zaus tswv oscillator uas ua hauj lwm tsis tu ncua, nws zaus yog nyob ib ncig ntawm 100 kHz. Tsis tas li ntawd nyob rau hauv Scheme flashing diode divider yog tam sim no, tau koom ua ke nyob rau hauv cov zajlus kom hais. Nws cais lub siab zaus nqi mus rau ib theem ntawm 1.5-3 Hz. Tej zaum koj yuav nug: "Tiam sis vim li cas siv ib tug high-zaus generator nrog ib tug divider, yog vim li cas nws yog tsis yooj yim sua rau siv ib tug tsawg-zaus oscillator, thiab yog li piv cov tsim?" Qhov no yog vim lub fact tias rau qhov kev siv ntawm cov generator ntawm tsawg zaus yuav tsum tau ib tug loj capacitance capacitor rau vremyaopredelyayuschey saw. Yuav kom siv xws li ib tug capacitor puas yuav tsum tau ib tug loj npaum li cas hauv cheeb tsam tshaj los ntawm kev siv ntawm high-zaus generator.

Yog li ntawd peb ntsia dab tsi yog ib tug flashing LED. Thiab nyob rau hauv lo lus nug uas yog zoo dua - los yog tsoos technology MSD qhia diodes los teb hais tias txawm lub cheapness ntawm lub thib ob, flashing diodes kuj pom lawv tau thiab tsis sib tw nrog cov tus tsoos.
