Usati watenga rambi redhesiki, pamusoro pekutarisa zvakatemwa, mabasa, uye mamiriro ekushandiswa, kuitira kuti uve nechokwadi chekuchengetedzwa, usazeye chiratidzo chetifiketi pane yekupakeji yekunze. Nekudaro, kune akawanda mareti etifiketi emarambi etafura, anorevei?
Parizvino, inenge yese mwenje we LED unoshandiswa, angave magirobhu kana machubhu emwenje. Munguva yakapfuura, mazhinji ezviratidziro zve LED zvaive pamwenje marambi uye marobhoti ezvigadzirwa zvemagetsi, uye vaisawanzopinda muhupenyu hwedu hwezuva nezuva. Nekudaro, sezvo tekinoroji yakura mumakore achangopfuura, marambi edhesiki re LED akawanda uye magirobhu akaonekwa, uye marambi emumugwagwa uye mwenje wemotokari zvakatsiviwa zvishoma nezvishoma nemarambi e LED. Pakati pavo, mwenje wedesiki re LED ane hunhu hwekuchengetedza simba, kusimba, chengetedzo, smart control, uye kuchengetedza kwezvakatipoteredza. Vane zvakawanda zvakanakira kupfuura zvechinyakare incandescent bulbs. Naizvozvo, marambi mazhinji edhesiki pamusika parizvino anoshandisa mwenje we LED.
Nekudaro, marambi mazhinji edhesiki pamusika anoshambadza maficha akadai seasina kuvheneka, anti-glare, ekuchengetedza simba, uye pasina mwenje weblue ngozi. Idzi ichokwadi here kana kuti inhema? Ita shuwa yekuchengeta maziso ako akavhurika uye utarise kune iyo label certification kuitira kuti utenge rambi redhesiki rine yakavimbiswa mhando uye chengetedzo.
Nezve "Safety Standards yeMarambi" mucherechedzo:
Kuitira kuchengetedza kodzero nezvido zvevatengi, nharaunda, chengetedzo, uye utsanana, uye kudzivirira zvigadzirwa zvakaderera kupinda mumusika, hurumende dziri munyika dzakasiyana dzine masisitimu ekunyora anoenderana nemitemo nemitemo yenyika. Iyi ndiyo inosungirwa kuchengetedza mwero munharaunda yega yega. Hapana mwero wekuchengetedza unopfuudzwa nenyika imwe neimwe. Zhang haakwanise kupinda munzvimbo kuti atengese zviri pamutemo. Kuburikidza nemarambi akajairwa aya, uchawana mucherechedzo unoenderana.
Nezve mwero wekuchengetedza marambi, nyika dzine mazita akasiyana uye mirau, asi iyo mirau inowanzogadzika zvichienderana neyakafanana zviyero zvepasi rose zveIEC (International Electrotechnical Commission). MuEU, iri CE, Japan iPSE, United States iETL, uye muChina ndiyo CCC (inozivikanwawo se3C) chitupa.
CCC inotaura kuti ndezvipi zvigadzirwa zvinofanirwa kuongororwa, zvichienderana nehunyanzvi hwekuita, maitiro ekushandisa, kucherechedzwa kwakabatana, nezvimwewo. Zvakakosha kuziva kuti zvitupa izvi hazvivimbise kunaka, asi ndiwo anonyanya kukosha mavara ekuchengetedza. Aya mavara anomiririra kuzvizivisa kwemugadziri kuti zvigadzirwa zvake zvinoenderana nemirairo yese yakakodzera.
MuUnited States, UL (Underwriters Laboratories) isangano repasi rose rakazvimiririra rekuyedza kuchengetedzwa nekuzivikanwa. Yakazvimiririra, haina purofiti, uye inoisa zviyero zvekuchengetedza veruzhinji. Ichi chitupa chekuzvidira, kwete chekumanikidza. UL certification ine kuvimbika kwepamusoro uye kuzivikanwa kwepamusoro pasirese. Vamwe vatengi vane ruzivo rwakasimba rwekuchengetedza chigadzirwa vanobhadhara zvakanyanya kuti chigadzirwa chine UL certification.
Standards nezve voltage:
Nezvekuchengetedzwa kwemagetsi kwemarambi edhesiki, nyika imwe neimwe ine mitemo yayo. Iyo inonyanya kuzivikanwa ndeyeEU LVD Low Voltage Directive, iyo ine chinangwa chekuona kuchengetedzeka kwemarambi etafura kana ashandiswa. Izvi zvakare zvakavakirwa paIEC tekinoroji zviyero.
Nezve low flicker standards:
“Low flicker” zvinoreva kudzikisira mutoro unokonzerwa nekupenya kwemaziso. Strobe ndiyo frequency yemwenje inochinja pakati pemavara akasiyana uye kupenya nekufamba kwenguva. Kutaura idi, kumwe kupenya, kwakadai semarambi emotokari yamapurisa nokudzima marambi, kunogona kunzwisiswa zvakajeka nesu; asi kutaura zvazviri, marambi edhesiki anopenya, ingori nyaya yekuti mushandisi anogona kuzvinzwa. Kukuvadza kunokwanisika kunokonzerwa nepamusoro-frequency flash zvinosanganisira: photosensitive pfari, musoro uye kusvotwa, kuneta kwemaziso, nezvimwe.
Zvinoenderana neInternet, iyo flicker inogona kuyedzwa kuburikidza nenhare mbozha kamera. Nekudaro, maererano nekutaura kweBeijing National Electric Light Source Quality Supervision uye Inspection Center, nhare mbozha kamera haigone kuongorora flicker/stroboscopic yezvigadzirwa zve LED. Iyi nzira haisi yesainzi.
Naizvozvo, zviri nani kutaura kune yepasi rose chiyero IEEE PAR 1789 yakaderera-flicker certification. Low-flicker desk marambi anopfuura iyo IEEE PAR 1789 yakajairwa ndiwo akanakisa. Pane zviratidzo zviviri zvekuyedza strobe: Percent Flicker (flicker ratio, iyo yakaderera kukosha, zvirinani) uye Frequency (flicker rate, iyo yakakwirira kukosha, zviri nani, isinganyanyi kunzwisiswa neziso remunhu). IEEE PAR 1789 ine seti yemafomula ekuverenga frequency. Kunyangwe iyo mwenje ichikonzera kukuvadza, zvinotsanangurwa kuti mwenje wekubuda frequency inodarika 3125Hz, iri nhanho isiri-ngozi, uye hapana chikonzero chekuona iyo flash ratio.
(Rambi rakapimwa chairo rinenge riri low-stroboscopic uye harikuvadzi. Pamufananidzo uri pamusoro apa pane kavara dema, zvichireva kuti kunyange zvazvo rambi racho risina ngozi inopenya, rinenge riri pedyo nenzvimbo ine ngozi. Pamufananidzo wezasi hapana mavara matema anooneka. zvachose, zvinoreva kuti mwenje uri mukati meiyo yakachengeteka strobe Mukati)
Certification nezve njodzi yechiedza cheblue
Nekuvandudzwa kwe LEDs, nyaya yeblue light hazards yakawanawo kuwedzera kutariswa. Pane zviyero zviviri zvinoenderana: IEC/EN 62471 uye IEC/TR 62778. IEC/EN 62471 yeEuropean Union ndiyo yakafaranuka yeoptical radiation hazard tests uye zvakare ndicho chinodiwa chakakosha pamwenje wedhesiki unokwanisa. Iyo International Electrotechnical Commission's IEC/TR 62778 inotarisa pane yebhuruu mwenje wengozi yekuongorora mwenje uye inokamura njodzi dzechiedza chebhuruu mumapoka mana kubva kuRG0 kuenda kuRG3:
RG0 - Hapana ngozi ye photobiohazard apo nguva yekuratidza retinal inodarika 10,000 seconds, uye hapana kunyorwa kunodiwa.
RG1- Hazvikurudzirwe kutarisa zvakananga kune mwenje sosi kwenguva yakareba, kusvika ku100 ~ 10,000 masekonzi. Hapana kumaka kunodiwa.
RG2-Haikodzeri kutarisa zvakananga kune mwenje sosi, yakakura 0.25 ~ 100 masekonzi. Yambiro yechenjedzo inofanira kuiswa.
RG3-Kutarisa zvakananga kuchiedza kunyange muchidimbu (<0.25 seconds) kune ngozi uye yambiro inofanira kuratidzwa.
Naizvozvo, zvinokurudzirwa kutenga marambi etafura anoenderana nezvose IEC/TR 62778 hazard-free uye IEC/EN 62471.
Label nezvekuchengetedzwa kwezvinhu
Kuchengetedzwa kwemidziyo yemwenje yedesk yakakosha. Kana zvinhu zvekugadzira zvine simbi dzinorema se lead, cadmium, uye mercury, zvinokonzeresa kukuvadza kumuviri wemunhu. Zita rakazara reEU RoHS (2002/95/EC) ndere "Directive paKurambidza uye Kudzora Zvinhu Zvinokuvadza Muzvigadzirwa zveMagetsi neMagetsi". Inochengetedza hutano hwevanhu nekudzora zvinhu zvine njodzi muzvigadzirwa uye inova nechokwadi chekuraswa kwemarara zvakakodzera kuchengetedza zvakatipoteredza. . Zvinokurudzirwa kutenga marambi edhesiki anopfuudza iyi kuraira kuti ave nechokwadi chekuchengetedza uye kuchena kwezvinhu.
Zviyero pamagetsi emagetsi
Electromagnetic fields (EMF) inogona kukonzera dzungu, kurutsa, leukemia yehucheche, maronda ehuropi akashata uye zvimwe zvirwere zviri mumuviri wemunhu, zvichikanganisa zvakanyanya hutano. Naizvozvo, kuitira kuchengetedza musoro wemunhu uye torso yakavhurika mwenje, marambi anotumirwa kuEU anofanirwa kuongororwa kuongororwa kweEMF uye anofanirwa kutevedzera zvinoenderana neEN 62493 standard.
Mucherechedzo wepasirese chitupa ndiyo tsigiro yakanakisa. Hazvina mhosva kuti vangani zviziviso zvinosimudzira chigadzirwa, hazvigone kuenzaniswa nekuvimbika uye chiratidzo chepamutemo chetifiketi. Naizvozvo, sarudza zvigadzirwa zvine zvitupa zvepasi rose kudzivirira kunyengedzwa uye kushandiswa zvisina kunaka. Kuwedzera rugare rwepfungwa uye hutano.
