Yadda za a inganta yadda ya kamata ƙara haske na LED fitilu?

LED (Haske Emitting Diode) tushen haske ne na kowa tare da fa'idodin inganci mai ƙarfi, aminci da tsawon rai. A yawancin aikace-aikace, sau da yawa muna buƙatar sarrafa hasken LEDs bisa ga buƙatu. Wannan labarin zai gabatar da wasu hanyoyin sarrafa haske na LED gama gari da ka'idodin su.

1. Daidaita halin yanzu

Daidaita halin yanzu yana ɗaya daga cikin mafi sauƙi hanyoyin canza haske na LED ta canza halin yanzu ta hanyarsa. Babban halin yanzu zai sa LED ɗin ya yi haske, yayin da ƙaramar halin yanzu zai sa ya dimmer. Wannan hanya tana aiki don sauƙaƙe LED da'irori kuma ana iya aiwatarwa ta hanyar daidaita tushen yanzu, resistor, ko direba na yanzu.

2. Pulse width modulation (PWM)

Pulse width modulation (PWM) fasaha ce da ake amfani da ita sosai a sarrafa hasken LED. PWM yana sarrafa haske ta daidaita girman bugun bugun jini da mitar LEDs. Ka'idarsa ita ce canza yanayin lokaci na babban matakin da ƙananan matakin bugun jini a cikin kowane zagayowar, ta haka ne ke daidaita tasirin haske daban-daban. Idan aka kwatanta da daidaitawa na yanzu, PWM na iya cimma daidaiton daidaitawar haske mafi girma da ƙarancin amfani da wutar lantarki.

3. Yi amfani da m resistor

A m resistor (kamar potentiometer) wani abu ne na gama gari da ake amfani dashi don sarrafa hasken LED. Ta hanyar haɗa resistor mai canzawa zuwa da'irar LED, ana iya sarrafa haske ta hanyar canza kwararar ta yanzu ta hanyar daidaita juriya na resistor. Daidaita juriya na resistor na iya daidaita hasken LED sosai da fahimta, amma kewayon daidaitawarsa na iya iyakancewa.

4. Yi amfani da madaidaicin tushen yanzu

Madadin da'irar tushen halin yanzu hanya ce ta gama gari ta tuƙi LED, wanda ke canza haske ta hanyar daidaita madaidaicin tushen yanzu. Madogararsa na yau da kullun na iya samar da tsayayyen halin yanzu don kiyaye daidaiton haske na LED. Wannan hanyar ta dace da aikace-aikace waɗanda ke buƙatar daidaitaccen sarrafa hasken LED kuma suna buƙatar kwanciyar hankali.

5. Yi amfani da guntu mai sarrafa haske

Wasu takamaiman guntuwar direba na LED suna da aikin sarrafa haske wanda zai iya daidaita haske ta siginonin sarrafawa na waje (kamar shigar da PWM). Waɗannan kwakwalwan kwamfuta suna haɗa da'irorin daidaita haske don cimma daidaitaccen sarrafa haske. Amfani da wannan guntu yana sauƙaƙa ƙirar kewayawa kuma yana ba da ƙarin zaɓuɓɓukan sarrafawa masu sassauƙa.

Don taƙaitawa, akwai zaɓuɓɓuka da yawa don sarrafa hasken LED, gami da daidaitawa na halin yanzu, daidaitawa mai faɗin bugun jini, ta yin amfani da masu tsattsauran ra'ayi, madaidaicin tushen yanzu da kwakwalwan sarrafa haske. Kowace hanya tana da yanayin yanayi da ƙa'idodinta. Zaɓin hanyar da ta dace bisa ga takamaiman buƙatu na iya cimma ikon sarrafa LED wanda ya dace da buƙatun haske.
