Matambudziko Anowanzo Nekupenya Diodes Ari

Wakambosangana nematambudziko akawanda asinganzwisisi here, uye ndeapi matambudziko akajairika? Sei iyo light-emitting diode isingaite overvoltage kana overcurrent inoshandisa mwenje chena LED? Zvichitaurwa zviri nyore, inotsanangurwa neinonyanya kushandiswa 5mm chena mwenje LED. Yayo yakajairika kushanda voltage kazhinji mukati me3.0-3.5V renji, uye yakajairika kushanda ikozvino 20mA 20mA. Zvisinei, vanhu vazhinji vanofunga zvisiri izvo kuti kushandiswa kwechiedza chichena LEDs ne-over-voltage kana overcurrent chichave chakajeka, uye mhedzisiro chaiyo yebvunzo ndeyokuti mushure me15mA, iyo optical flux inowedzera zvakanyanya. Mushure me20mA, panenge pasina kuona-kuburikidza. Asi pane fivha iri pachena. Kune zvakare bvunzo yehupenyu: 20mA yakashanda kwemwedzi, uye attenuation inongova 5%. Ikozvino kune 95% Optical flux. Kana 30mA ichishanda kusvika mazuva gumi nemapfumbamwe, vhoriyamu yechiedza inongova 50%. Zvinogona kutaridzirwa kuti chiedza chichena LED chinogona kushanda maawa 100 000 pasi pemamiriro ezvinhu akajairika inoshandiswa mumhepo huru, nehupenyu hwemaawa 600 chete! Ma LED anogona kushandiswa kweanopfuura maawa 50,000 mukutsanangurwa kwakawanda, uye vamwe vagadziri vanoti Iyo LED inogona kushanda maawa anenge 100,000, asi izvi hazvivimbise kuti zvigadzirwa zve LED zvinogona kushandiswa kwenguva yakareba. Iyo isiriyo mashandiro uye maitiro anogona nyore “Paradzai ”Ma LED, ma LED anozoderera zvishoma nezvishoma nekufamba kwenguva. Kumwe kufanotaura kunoratidza kuti ma LED emhando yepamusoro anogona kuchengetedza kupfuura 60% yechiedza chekutanga kupenya mushure memaawa makumi mashanu ekushanda. Kuti uwedzere hupenyu hwe LED, zvakakosha kuderedza kana kubvisa zvachose simba rinopisa rinogadzirwa ne LED chip. Kupisa simba ndicho chikonzero chikuru nei LED ichimira kushanda. Izvi zvinotsanangurwa kushandiswa kwechiedza-emitting diodes. Kuti uwane rumwe ruzivo, ndapota nyorera online customer service consultation mamwe mashoko.
