Nhau dzemagariro uye zvakatipoteredza
Mukugadzira machipisi e LED, iyo inorganic acids, oxidants, complexing agents, hydrogen peroxide, organic solvents uye mamwe maajenti ekuchenesa anoshandiswa muchikamu chekugadzira substrate, pamwe nesimbi organic gasi chikamu uye ammonia gasi rinoshandiswa pakukura epitaxial, zvine muchetura. uye kusvibisa. Aya zvakare akajairwa kemikari zvinhu zvinowanzoshandiswa mukugadzira semiconductor integrated circuits uye mamwe maindasitiri. Kune makambani e LED chip ari eiyi yepamusoro-tech chikamu, yavo yekugadzira tekinoroji uye maitiro akasimba uye anoshanda, zvichiita kuti zvive nyore kuita kurapa kusingakuvadzi.
Ma LED ekudzora maturusi (anowanzozivikanwa sekutyaira magetsi emagetsi) haana kusiyana nemarambi echinyakare efluorescent, marambi esimbi halide, uye mamwe mabhora emagetsi, pamwe nehupfu uye zvinosvibisa zvinogadzirwa mukugadzirwa kwezvinhu zvakasiyana-siyana zvemagetsi zvevatengi.
Iyo inowanzo shandiswa aluminium alloy shell yemwenje ye LED yakafanana neyechinyakare aluminium alloy shell kugadzira, uye huturu uye zvinosvibisa zvinogadzirwa panguva yekugadzira epurasitiki kana simbi mateko hazvina kunyanya kuwedzera.
Muchidimbu, hapana chikonzero chekunetseka nezve semiconductor mwenje zvigadzirwa izvo vanhu vanosangana nazvo zvakananga, pamwe nenyaya dzezvakatipoteredza panguva yekugadzira.

Zvinetso zvekuchengeteka kwevanhu
1. Low LED voltage yakachengeteka zvikuru uye inotsausa kuvanhu
Vazhinji vashandi vehunyanzvi mumabhizinesi vane kudzika uye kusakwana kwekunzwisisa kwekuchengetedzwa kwemagetsi ezvigadzirwa zvemwenje zve LED uye magetsi ekufambisa, izvo zvinotungamira kuchengetedzeka kwemagetsi kwevazhinji vakagadzirwa uye vakagadzira zvigadzirwa zvemwenje zve LED zvichivimba zvachose nekuchengetedzwa kwemagetsi ekutyaira. Nekudaro, kuparadzaniswa kwemagetsi uye kuvharirwa kweakawanda anotsigira LED kutyaira magetsi emagetsi haakwane zvinodikanwa. Pamusoro pezvo, huwandu hukuru hwekusimudzira nezve kuchengetedzeka kwe low voltage LED inogona kutsausa vanhu kuti vagare vachibata zvigadzirwa, zvichikonzera njodzi yakakura yekuvhunduka kwemagetsi kupfuura zvigadzirwa zvemwenje zvechinyakare izvo vanhu vasingazive kuti simba ravo repamusoro rine njodzi uye vanoshinga kubata zvisina basa. .
2. LED blue light hazard issue
Bhuruu chip mhando chena LED ine spectrum iyo yakanyanya kunyura mune inokuvadza kupfuura mwenje wefluorescent, kusanganisira marambi ekuchengetedza simba, zvichikonzera spectrum inokuvadza zvakapetwa kaviri semarambi efluorescent. Pamusoro pezvo, nzvimbo yekuburitsa idiki uye kupenya kwakakwira, zvichiita kuti kukuvadza kwechiedza chebhuruu kuve kwakanyanya kupfuura mamwe marambi. Nekudaro, mudzidziso uye yenguva refu chigadzirwa chekuchengetedza certification bvunzo, mukuita, isingasviki 5% yemarambi edhesiki re LED anodarika izvo zvinodikanwa zveRG1. Mwenje iyi inongoda kunyorwa nechiratidzo chekuti “Usatarise zvakananga patsime rechiedza kwenguva yakareba” munzvimbo ine mukurumbira uye inoratidza chikumbaridzo chakachengeteka chekuyeuchidza vashandisi kuti vasangane nezvinodiwa. Zvinogona kutengeswa uye kushandiswa pasina matambudziko, izvo zvakachengeteka zvakanyanya pane kutarisa zvakananga pachiedza chezuva kwenguva pfupi. Uye nekuwedzera kwechifukidziro chejecha, magetsi e LED haana matambudziko. Uye haasi ma LED chete anounza biosafety nyaya. Muchokwadi, mamwe mwenje echinyakare masosi, akadai ekutanga simbi halide marambi, anogona kunge aine yakanyanya kusimba UV uye kunyange yebhuruu mwenje njodzi.
3. Strobe issue
Zvinofanira kutaurwa kuti zvigadzirwa zvemwenje zve LED zvinogona kunge zvisinganyanyi kupenya uye zvakanyanya kugadzikana mukuburitsa mwenje (senge yakawanda inofananidzira yakachena DC magetsi emagetsi madhiraivha pamusika). Uye zvigadzirwa zvisina kugadzirwa zvakanaka zvinogona zvakare kufinyamisa zvakanyanya (sezviya zvisina magetsi ekufambisa, uko gidhi remagetsi reAC rinopa simba kune tambo ye LED kana COB-LED), asi izvi hazvina kunyanya kusiyana nedambudziko rekufirika kwechubhu yakatwasuka. mwenje wefluorescent ane inductive ballast. Izvi hazvibvi pane mwenje we LED sosi, asi pane magetsi uye kutyaira sosi yemagetsi inoenderana nayo. Izvi zvinoshandawo pakupenya kwezvigadzirwa zvemwenje zvechinyakare.
