Nigute ushobora guhitamo amashanyarazi kumatara ya LED?

1. Kugura ibipimo ngenderwaho byo gutanga amashanyarazi

Ibipimo byo gutoranya kumashanyarazi yumuriro bitanga cyane cyane uburebure bwumurongo wumucyo, imbaraga numuyoboro wumucyo. Ibipimo byihariye byo guhitamo ni ibi bikurikira:

1. Uburebure bwumucyo: Guhitamo amashanyarazi akwiranye ukurikije uburebure bwumucyo birashobora kongera cyane ubuzima bwa serivisi no gutuza.

2. Imbaraga z'umucyo: Hitamo amashanyarazi akwiranye ukurikije imbaraga z'umucyo. Nimbaraga nini, niko amashanyarazi asabwa.

3. Ibiriho: Hitamo amashanyarazi akwiranye ukurikije icyerekezo cyumucyo. Nibyinshi bigezweho, niko amashanyarazi asabwa.

2. Ibisobanuro byumuriro utanga amashanyarazi

1. 12V itanga amashanyarazi: ibereye ibara rimwe-ryaka-rike-RGB yumucyo, cyane cyane kumurongo muto.

2. 24V itanga amashanyarazi: ikwiranye ningufu nyinshi za RGB imirongo yumucyo nimirongo miremire.

3. 48V itanga amashanyarazi: ikwiranye numurongo mwinshi wumucyo wera, kandi ikwiranye numucyo uvanga urumuri rwera numucyo wa RGB.

3. Nigute ushobora kubara neza ubushobozi bwumuriro wamashanyarazi

Inzira yo kubara imbaraga zumurongo wumucyo ni: uburebure bwumurongo wumucyo (metero) × imbaraga (W / M) efficiency ingufu (%) × coefficient (1.2). Coefficient ni 1.2 kugirango umutekano wizewe.

Kurugero: Waguze umurongo wa 12V 5050 urumuri rufite uburebure bwa metero 5, ingufu za 14.4W / M, nubushobozi bwa 90%. Ukurikije formulaire, dushobora kubona:

5 (metero) × 14.4 (W / M) ÷ 90% × 1.2 = 96W

Kubwibyo, ugomba guhitamo amashanyarazi ya 12V afite ingufu za 96W.

4. Nigute ushobora gushiraho amashanyarazi yumuriro

1. Amashanyarazi yumucyo agomba gushyirwaho muburyo butarimo amazi kandi ukagerageza kwirinda gutose.

2. Mbere yo kwishyiriraho, ugomba gusuzuma niba voltage yagabanijwe yumuriro w'amashanyarazi hamwe na voltage yagereranijwe yumucyo uhuza.

3. Sukura umwobo wo gukwirakwiza ubushyuhe buri gihe kugirango amashanyarazi agabanuke.

Muri make, ni ngombwa guhitamo amashanyarazi akwiye kugira ngo atange amashanyarazi, adashobora kongera igihe cyumurimo wumurongo wumucyo, ariko kandi anemeza urumuri ningaruka zumucyo. Niba utazi neza uburyo bwo guhitamo amashanyarazi akwiye, urashobora kubaza abatekinisiye babigize umwuga.
