Mhedzisiro yesimba pa LED Headlamps

Simba chinhu chakakosha parameter yemarambi akatungamira, zvisineirechargeable LED marambikana Dry LED marambi. Saka ngatiwedzere kunzwisisa kuti chii chinonzi simba.

1、Simba
Iyo simba chinhu chinoratidza kugona kweMwenje we LEDkuburitsa simba rinoshanda. Simba chiyero chehuwandu hwekufambisa kwesimba, uye mumagetsi eDDC ndiyo chibereko chemagetsi V uye ikozvino A. Mu AC system, inonyanya kuoma: imwe AC ikozvino inotenderera mumutoro, iyo inonzi reactance current kana harmonic current, iyo inoita kuti simba rinoratidzika (voltage Volt neAmps ikozvino) yakakura kudarika simba chairo. Musiyano pakati pesimba rinoratidzika uye simba chairo rinotungamira kune chinhu chesimba, uye chinhu chesimba chakaenzana nereshiyo yesimba chairo kune simba rinoonekwa. Saka iro chairo simba muAC system yakaenzana neinotsamira simba nguva iyo simba chinhu.
Ndiko kuti: simba chinhu = simba chairo / rinooneka simba. Izvo chete simba rekugadzirisa mutsara wakadai semagetsi heater uye chiedza girobhu ndeye 1. Musiyano pakati pesimba chairo uye simba rinoratidzika remichina yakawanda iduku zvikuru uye isingakoshi, asi musiyano pakati pemichina ye capacitive yakadai semarambi yakakura zvikuru uye inokosha.

2. Simba rinooneka
Active simba: chigadzirwa che AC voltage uye AC ikozvino. Neformula se: S=UI. Iko S inotarwa simba rekubuda muVA (volt-ampere); U yakatemerwa kubuda kwemagetsi muV, senge 220V, 380V, nezvimwewo; Ini ndakayerwa kubuda ikozvino muA. Simba rinoratidzika rine zvikamu zviviri: rinoshanda simba (P) uye reactive simba (Q). Simba rinoshanda rinoreva chikamu chebasa rakaitwa zvakananga. Semuenzaniso, mwenje kumusoro, iyo mota kutenderera, iyo yemagetsi dunhu inoshanda. Nokuti simba iri rave kupisa, rinogona kunzwiwa zvakananga nevanhu, saka vamwe vanhu vane fungidziro, ndiko kuti, simba rinoshanda sesimba rinoratidzika, ndiani anoziva simba rinoshanda rinongova chikamu che
Simba rinoratidzika, rine fomula: P = Scos θ = UIcosθ = UIF. Apo P ndiro simba rinoshanda muW (watts); F = cos θ inodaidzwa kuti simba chinhu, uye θ ndiyo mutsauko wechikamu chemhando dzakasiyana dzemagetsi pamutoro usiri mutsetse. Reactive simba chikamu chesimba rakachengetwa mudunhu asi risingashandiswe zvakananga, rinoratidzwa neformula: Q = Ssin θ = UIsinθ. Iko Q ndiyo simba rinoshanda mu var (kushaya).

ForLed headlampsuye mamwe ese emagetsi maseketi anoshanda paDC voltage, hazvibviri kushanda pasina simba.
