For Led Downlight: Musiyano Pakati peLens & Reflector

Mavhenekera epasi anogona kuoneka kwese kwese muhupenyu hwedu hwezuva nezuva. Kunewo mhando dzakawanda dzemalights. Nhasi tichataura nezve musiyano uripo pakati peinopenya kapu pasi mwenje uye lens pasi mwenje.

Chii chinonzi Lenzi?

Chinhu chikuru chelens ndeye PMMA, ine mukana wepurasitiki yakanaka uye yakakwirira mwenje transmittance (kusvika 93%). Izvo zvisingabatsiri ndezvishoma tembiricha kuramba, chete anenge 90 madhigirii. Iyo yechipiri lens inowanzo gadzirwa ine yakazara yemukati kuratidza (TIR). Iyo lens yakagadzirwa nechiedza chinopinda kumberi, uye iyo conical surface inogona kuunganidza uye kuratidza ese mwenje wepadivi. Iko kupindirana kwemhando mbiri dzechiedza kunogona kuwana yakakwana kushandiswa kwechiedza uye yakanaka mavara maitiro.

Chii chinonzi TIR?

TIR inoreva "Total Internal Reflection", inova chiitiko chemaziso. Kana mwaranzi ichipinda mukati mepakati ine yakakwira refractive indekisi mune svikiro ine yakaderera refractive index, kana chiitiko cheAngle chiri chikuru pane yakakosha Angle θc (mwaranzi iri kure neyakajairwa), iyo yakasarudzika ray inopera uye chiitiko chose. ray icharatidzwa uye kwete kupinda mukati neine yakaderera refractive index.

TIR lens: kunatsiridza LED chiedza simba kushandiswa

TIR lens inotora musimboti wekufungidzira kwakazara, iyo inogadzirwa nekuunganidza uyekugadzirisa chiedza. Yakagadzirirwa kutarisa mwenje yakananga kumberi nemhando inopinda mukati uye iyo conical surface inogona kuunganidza uye kuratidza ese mwenje wepadivi.. Kupindirana kweaya marudzi maviri emwenje kunogona kuwana mwenje wakakwana wokushandisa uye yakanaka nzvimbo.

Kubudirira kweTIR lens kunogona kusvika kune zvinopfuura 90%, nezvakanaka zvekushandiswa kwesimba rechiedza chakakwirira, kurasikirwa kwechiedza zvishoma, nzvimbo duku yekuunganidza chiedza uye kufanana kwakanaka, etc. TIR lens inonyanya kushandiswa mumarambi maduku-makona (beam Angle <60 °), senge malights uye malights.

Chii chinonzi reflector?

Reflective cup ndeyekunongedza kushandisa mwenje sosi girobhu semwenje sosi, iyo inoratidzira inoda chinhambwe kuti iunganidze mwenje inovhenekera, kazhinji rudzi rwekapu, inowanzozivikanwa serelightive cup. Kazhinji, iyo LED mwenje sosi inoburitsa mwenje paAngle inosvika zana nemakumi maviri°. Kuti uwane iyo yaunoda optical mhedzisiro, mwenje dzimwe nguva inoshandisa rekisheni kudzora chinhambwe chekuvhenekesa, nzvimbo yekuvhenekera, uye mhedzisiro.

Metal reflector: Inoda stamping & polishing tekinoroji uye ine deformation memory. Iyo inobatsira inodhura yakaderera uye inodzivirira tembiricha. Inowanzo shandiswa kune yakaderera giredhi kuvhenekera zvinodiwa.

Plastic Reflector: Inongoda demould imwe chete. Iyo mukana ndeye yakakwira optical precision uye hapana deformation memory. Mari yacho ine mwero uye yakakodzera mwenje iyo tembiricha haina kukwirira. Inowanzoshandiswa kune yepakati uye yepamusoro giredhi yekuvhenekesa zvinodiwa.

Saka ndeupi musiyano uripo pakati peTIR lens nekapu inofungidzira? Muchokwadi, iwo musimboti wekushanda wavo wakafanana, asi tichitaura, TIR lenzi dzine kurasikirwa kushoma kweiyo yekuratidzira interface.

TIR lens: Kudyidzana pakati peyese yekuratidzira tekinoroji uye yepakati, ine zvese zvemuviri nemakemikari maitiro. Imwe neimwe ray inodzorwa uye inoshandiswa, kazhinji isina yechipiri mavara, uye rudzi rwechiedza rwakanaka. Iyo lenzi yakatenderedzwa uye danda repakati rakanyanya yunifomu.Nzvimbo yechiedza ye lens inenge yakafanana, kumucheto kwechiedza chechiedza chakatenderera, uye kuchinja kwakasikwa. Inokodzera nzvimbo ine chiedza chekudzika sechiedza chekutanga, uye inokodzerawo nzvimbo ine yunifomu fungidziro. Iyo lens nzvimbo yakajeka, mutsara wekuparadzanisa hausi pachena, uye mwenje unononoka wakanyanya kufanana.

Reflectkana: Chiedza chekudzora chekuratidzira chakachena. Asi zvishoma nokudanzvimbo yechipiriof chiedza ndichohombe. Major light through cup surface reflectionanoendakunze, chiedzamhando inosarudzwanemukombe pamusoro.Muhukuru hwakafanana uyeangle yenyaya, nekuti mwenje wepakatiangle yemukombe inoratidzira yakakura, saka anti glare ichave nani. Chikamu chikuru chechiedza hachibatanidzi nechitarisiko chepamusoro hachidzorwi, nzvimbo yechipiri yakakura. Reflective kapu yechiedza kunze kwemupendero uyeangle pfungwa yakasimba, pakati pechiedza chechiedza chakasimba uye chiri kure.

Kapu inovhenekera ine yakawedzera kunyura yepakati chiedza nzvimbo uye inverted V-yakaita mupendero, iyo inokodzera mapikicha ane ane mukurumbira mativi madiki. Reflective cup light spot iri kujeka, kucheka mwenje kumucheto secant mutsetse unonyanya kuoneka.

Kana iwe ukabvunza kuti ndeipi iri nani, TIR lenzi kana kuratidzaor? Izvozvo zvinofanira kufungwa nezvazvo nokuda kwezvinangwa zvinoshanda. Chero bedzi ichigona kuzadzisa chinodiwa optical mhedzisiro, yakanaka optical mudziyo. Somuenzaniso, chiedza che LED chinowanzobudisa chiedza paAngle inenge 120 °. Kuti uwane iyo yaunoda optical mhedzisiro, mwenje dzimwe nguva inoshandisa kapu inopenya kudzora chinhambwe chechiedza, nzvimbo yechiedza, uye chiedza chemavara.
