Bwe tugenda mu maaso n'ensi y'amataala naddala abavuzi ba LED n'enkola za dimming, ekigambo 'dimming curve' kitera okuvaayo. Endowooza eno nkulu nnyo kuba efuga engeri okwakaayakana kw’ekitangaala gye kukyuka mu kuddamu siginiini eyingizibwa, ka kibeere nga kizikira okuva ku kitangaala okudda mu kizikiza oba vice versa. Enkokola y’okuzibikira ekwata butereevu ku bumanyirivu n’enkola y’okuzibikira okutwalira awamu.
Dimming curve kye ki?
Dimming curve mu bukulu gwe mulimu ogwateekebwawo nga tegunnabaawo ogulagira engeri ekyuma ekizikiza gye kivvuunula siginiini eyingizibwa mu ddaala erikwatagana ery’okufuluma kw’ekitangaala. Kikola nga pulaani y’engeri okumasamasa gye kutereezaamu okusinziira ku siginiini y’okufuga ewereddwa.
Waliwo ebika bya dimming curves ebiwerako, nga buli emu erina engeri zaayo ez’enjawulo n’okukozesebwa kwayo. Ebisinga okusangibwa mulimu linear, logarithmic, gamma, ne exponential dimming curves. Ka twekenneenye buli kimu ku bino mu bujjuvu.
Linear dimming curve Enkokola ya linear dimming curve mpozzi y’esinga okuba ennyangu era esinga obutereevu. Mu mbeera eno, akabonero k’okuzikira (dimming signal) kageraageranye butereevu n’enkyukakyuka mu kumasamasa kw’ekitangaala. Okugeza, singa siginiini y’okuzibikira yeeyongera ebitundu 10%, okumasamasa kw’ekitangaala nakyo kijja kweyongera ebitundu 10%, era kye kimu kikola mu ngeri ey’okudda emabega. Ekika kino eky’okuzibikira (dimming curve) kitera okwettanirwa mu bifo ng’okufuga okutuufu ku kwaka kwetaagisa, gamba nga mu bifo eby’okwolesezaamu oba mu situdiyo.
Linear dimming curve
Wadde nga linear dimming curve nnyangu okutegeera n’okufuga, eyinza obutakwatagana bulijjo n’engeri eriiso ly’omuntu gye lilabamu ekitangaala. Eriiso ly’omuntu litegeera nnyo enkyukakyuka mu kwakaayakana ku kitangaala ekitono, ne lizuula n’okweyongera oba okukendeera okutonotono. Kyokka, ku mitendera egy’okumasamasa egy’amaanyi, eriiso terifuuka nnyo ku nkyukakyuka zino.
Logarithmic dimming curve Okusobola okukwatagana obulungi n’engeri y’okulaba kw’eriiso ly’omuntu, logarithmic dimming curve yakolebwa. Okwawukana ku kikonde kya layini, ekiwujjo kya logarithmic dimming curve kisobozesa enkyukakyuka mpolampola mu kwakaayakana ku madaala aga wansi, ekivaamu enkyukakyuka ey’obutonde ennyo. Ku mitendera gy’okumasamasa egy’oku ntikko, enkyukakyuka mu kumasamasa eba ya mangu, ekintu ekitalabika nnyo mu liiso ly’omuntu. Curve eno ekola bulungi nnyo mu dizayini y’okutaasa naddala mu mbeera nga okutumbula ekikolwa ky’okuzibikira n’okukwatagana n’okutegeera kw’omuntu okulaba bikulu nnyo.

Gamma okuzikira curve
Gamma dimming curve enyonyola enkolagana etali ya linnya wakati w’akabonero k’okumasamasa n’okumasamasa kwennyini okulowoozebwa eriiso ly’omuntu. Nga tutereeza omuwendo gwa gamma, engabanya y’okumasamasa mu kitundu ekitangalijja esobola okulongoosebwa obulungi. Kino kivaamu ekitangaala ekifaanagana era ekigonvu, ekikendeeza ku kumasamasa n’ebisiikirize.
Kikulu okumanya nti enkokola ya gamma dimming si curve emu wabula wabula famire ya curves. Omuwendo gwa gamma bwe guteekebwa ku 1.0, ekiwujjo kifuuka layini engolokofu ku nkoona ya 45° eri ekisiki kya koodinati, mu bukulu nga kifaananako ekiwujjo ky’okuzibikira eky’ennyiriri. Okwetegereza kulaga nti omuwendo gwa gamma gukosa ekiwujjo ky’okuzikira mu ngeri eno wammanga: mu bitundu ebiddugavu (nga enkwatagana ey’okwebungulula eri wansi wa 30%), omuwendo gwa gamma ogw’oku ntikko guviirako enkyukakyuka ennyangu, ate omuwendo gwa gamma ogwa wansi guvaamu enkyukakyuka ez’amaanyi.

Oluvannyuma lw’okwetegereza ebikosa eby’enjawulo eby’emiwendo gya Gamma egy’enjawulo ku kiwujjo ekizikiza, tujja kusanga ekintu ng’ekyo: nga tufudde nti ekitundu ky’ekikulukusi ekirina enkwatagana ey’okwebungulula eri wansi wa 30% kye kitundu ekiddugavu, omuwendo gwa Gamma gye gukoma okuba omunene, enkyukakyuka y’ekitundu ekiddugavu gy’ekoma okubeera ennyangu, ate omuwendo gwa Gamma gye gukoma okuba omutono, n’enkyukakyuka y’ekitundu ekiddugavu gye kikoma okubeera ekinene.

Enkokola y’okuzikira okw’ekigero Mu nkulungo y’okuzibikira okw’ekigero, okumasamasa kw’ekitangaala kukwatagana mu ngeri ey’ekigero ne siginiini eyingizibwa. Nga siginiini eyingizibwa yeeyongera, okumasamasa kw’ekitangaala kweyongera mpola mu kitundu ky’amaanyi amatono ate mu kitundu eky’amaanyi amangi.
Enkokola y’ensengekera (exponential curve) era nkyukakyuka (dimming curve) ekwatagana n’engeri y’okutegeera kw’eriiso ly’omuntu, kubanga eyaka mpola ku musana omutono, eyaka mangu mu kitundu ekisembayo, era ekyuka mangu mu kitundu eky’okumasamasa okw’amaanyi, ekitali kyangu kuzuulibwa liiso lya muntu era nga kikwatagana n’engeri y’okutegeera kw’eriiso ly’omuntu.
Nga tukozesa enkokola ez’enjawulo ez’okuzikira, ebyetaago eby’enjawulo eby’okutaasa mu kitundu ekiddugavu bisobola okutuukibwako obulungi. Okugeza, mu bifo ebitongole nga myuziyamu, ebifo ebirimu enzikiza bitera okwetaaga okufuga amataala mu ngeri ennyangu, ekiyinza okukakasa nti abagenyi basobola okulaba obulungi ebikwata ku by’okwolesebwa awatali kwonoona by’okwolesebwa olw’ekitangaala ekisusse.
Gyaanyisa dimmers ez’enjawulo
Nga dimming stroke ya dimmer si linear ne output brightness signal, bw’oba oyagala output ekitangaala okukyuka linearly, dimming curve ey’enjawulo yeetaagibwa.
Okuyita mu kunnyonnyola waggulu, nzikiriza nti buli muntu alina okutegeera okusooka ku dimming curves. Kati, ka tuddeyo endowooza eno mu nkola ey’enkola. Olw’okukulaakulana kwa tekinologiya okutambula obutasalako, abakozesa bataddewo ebyetaago eby’oku ntikko olw’obwangu bw’okukozesa dimming curve.
Nga omukugu mu China omukozi wa ddereeva amagezi agaziba, SCPOWER/Suretron etuuse ku customization ya dimming curves okuyita mu buyiiya bwa tekinologiya, okutuukiriza obulungi ebyetaago by’abakozesa eby’okukozesa ku dimming curves.
High-Power Constant Current Ddereeva wa LED asobola okuzikira
Esobozesa abakozesa okulongoosa dimming curves
Nga tutwala SCPOWER/Suretron constant current high-power series intelligent dimming driver nga ekyokulabirako, series eno esobola okulonda linear, logarithmic oba gamma dimming curve okuyita mu nkola ya NFC, okusobozesa abakozesa okulonda mu ngeri ekyukakyuka dimming curve esinga okusaanira okusinziira ku mbeera y’okukozesa entongole, ebyetaago by’okutaasa oba by’ayagala. ill carefully preset a variety of dimming curve schemes based on the actual application scenarios, lighting needs or personal preferences of different customers, okukekkereza bakasitoma emitendera egy’okwetereeza egy’obuzibu, okukekkereza obulungi obudde n’amaanyi g’abakozesa, n’okukakasa obutuufu bw’okuzikira, okulongoosa obulungi ebikolwa by’okutaasa. Omulongooti gw’okulonda ebintuBwe kiba kyetaagisa, oleke ebikukwatako mu kasanduuko k’obubaka era tujja kukutuukirira mu ssaawa 24 zokka.圣昌产品:DALI-2 | 可控硅 | 0/1-10V | DMX512 | Omukutu gwa yintaneeti (蓝牙/ZigBee/Wi-Fi)| 户外大功率 | CASAMBI圣昌展会: 2024香港秋灯展 | 2024广州光亚展 | 2024法兰克福照明展| 2024香港春灯展| 2023云知光论坛| 2023光亚展 | 2023广州设计周X云知光| 2022光亚展 | 2022法兰克福照明展
