Ungakhetha kanjani ukunikezwa kwamandla emigqeni yokukhanya ye-LED?

1. Imibandela yokuthenga yokunikezwa kwamandla kamugqa wokukhanya

Imibandela yokukhetha yokunikezwa kwamandla kamugqa wokukhanya ikakhulukazi ihlanganisa ubude bomugqa wokukhanya, amandla kanye namandla omugqa wokukhanya. Imibandela yokukhetha ethize imi kanje:

1. Ubude bomugqa okhanyayo: Ukukhetha ukunikezwa kwamandla okufanelekile ngokuya ngobude bomugqa wokukhanya kungakhuphula kakhulu impilo yesevisi nokuzinza.

2. Amandla omugqa wokukhanya: Khetha ukunikezwa kwamandla okuhambisanayo ngokwamandla omugqa wokukhanya. Uma unamandla amakhulu, kudingeka ukunikezwa kwamandla.

3. Okwamanje: Khetha ukunikezwa kwamandla okuhambisanayo ngokuya ngokusebenza komugqa wokukhanya. Uma i-current iba nkulu, kudingeka ukunikezwa kwamandla.

2. Ukucaciswa kokunikezwa kwamandla omugqa wokukhanya

1. Ukunikezwa kwamandla okungu-12V: kulungele imichilo yokukhanya ye-RGB enombala owodwa kanye nokukhanya okuphansi, ikakhulukazi emicu yokukhanya emifushane.

2. Ukunikezwa kwamandla okungu-24V: kulungele imichilo yokukhanya ye-RGB enamandla amakhulu nemichilo yokukhanya emide.

3. Ukunikezwa kwamandla okungu-48V: kulungele imichilo yokukhanya emhlophe enamandla amakhulu, futhi ifanele imichilo yokukhanya exuba ukukhanya okumhlophe nokukhanya kwe-RGB.

3. Ungabala kanjani ngendlela efanele umthamo wokuphakelwa kwamandla omugqa wokukhanya

Ifomula yokubala umthamo wamandla womugqa wokukhanya ithi: ubude bomugqa wokukhanya (imitha) × amandla (W/M) ÷ ukusebenza kahle kwamandla (%) × i-coefficient (1.2). I-coefficient ingu-1.2 ukuqinisekisa ukuphepha nokuthembeka.

Isibonelo: Uthenge umugqa wokukhanya ongu-12V 5050 onokubude bamamitha angu-5, amandla angu-14.4W/M, kanye nokusebenza kahle kwamandla okungu-90%. Ngokwefomula, singathola:

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

Ngakho-ke, udinga ukukhetha i-12V amandla kagesi enamandla angu-96W.

4. Indlela yokufaka ugesi womugqa wokukhanya

1. Ugesi womugqa wokukhanya udinga ukufakwa ngendlela engangeni manzi futhi uzame ukugwema ukuba manzi.

2. Ngaphambi kokufaka, udinga ukuhlola ukuthi ingabe i-voltage elinganiselwe yomthombo wamandla kanye ne-voltage elinganiselwe yomugqa wokukhanya kuyahambelana.

3. Hlanza izimbobo zokukhipha ukushisa zokunikezwa kwamandla njalo ukuze uqinisekise umphumela wokuqeda ukushisa.

Ngamafuphi, kubalulekile ukukhetha ukunikezwa kwamandla okufanelekile komugqa wokukhanya, okungakwazi nje ukwelula impilo yesevisi yomugqa wokukhanya, kodwa futhi kuqinisekise ukugqama kanye nomthelela womugqa wokukhanya. Uma ungaqiniseki ukuthi ungakhetha kanjani ukunikezwa kwamandla okufanelekile, ungathintana nochwepheshe abafanelekile.
