Semuyenzaniso, Lumileds LUXION COB inoshandisa eutectic soldering tekinoroji kubatanidza 121 0.5W machipi pane denderedzwa substrate ine dhayamita ye19mm, iine simba rose re60W. Iyo chip spacing inomanikidzwa kusvika 0.3mm, uye nerubatsiro rweyakakosha inopenya mhango, kufanana kwekugovera kwechiedza kunodarika 90%. Iyi yakasanganiswa yekurongedza haingorerutsa maitiro ekugadzira, asi zvakare inogadzira nzira nyowani ye "light source semodule", ichipa hwaro hwekuchinjalightingdhizaini, sekupa pre made equisite modules evagadziri vemwenje, inovandudza zvakanyanya kugona kwekugadzira nekugadzira.

Iro LED imwe chete ndeye Lambertian mwenje sosi, inoburitsa mwenje pakona ingangoita 120 °, asi kusimba kwechiedza kunoratidza kudzikira kwakanyanya kwebapiro rebapiro repakati, senyeredzi inopenya, inopenya zvinopenya asi yakati pararira uye isina kurongeka. Kusangana nelightingzvinodiwa, zvinodikanwa kugadzirisa zvakare mwenje wekugovera curve kuburikidza neyechipiri optical dhizaini.
Kushandiswa kweTIR lenses mu lens system inogona kudzvinyirira emission angle kusvika 30 °, asi kurasikirwa kwechiedza kunogona kusvika 15% -20%; The parabolic reflector in the reflector scheme inogona kuwedzera simba repakati pechiedza, asi inobudisa mavara akajeka; Kana uchibatanidza ma LED akawanda, zvinodikanwa kuchengetedza nzvimbo yakakwana kudzivirira kusiyana kwemavara, izvo zvinogona kuwedzera kukora kwemwenje. Zvakafanana nekuedza kubatanidza pamwe chete mufananidzo wakakwana nenyeredzi mudenga rehusiku, asi zvinogara zvakaoma kudzivirira kuremara uye mimvuri.

Thermal management solution:hutsva kubva munzvimbo yekupisa kupisa kusvika kune system level kupisa conduction
Traditional LED chiedza sosi
Ma LED echinyakare anotora nhanho ina yekudziya conduction nzira ye "chip solid layer inotsigira PCB", ine yakaoma kupisa kwekupisa, senge nzira inomonereka, inotadzisa kukurumidza kupera kwekupisa. Panyaya yekupikisa kupisa kwemafuta, pane kusangana kwekushisa kwe 0.5-1.0 ℃/W pakati pe chip uye bracket; Mukutaura kwezvinhu zvinopisa kupisa, iyo thermal conductivity yeFR-4 board inongova 0.3W / m · K, iyo inova bhodhoro rekupisa kupisa; Pasi pekuwedzera kwekuita, hotspots dzemuno dzinogona kuwedzera tembiricha yekusangana ne20-30 ℃ kana akawanda maLED akasanganiswa.
Data rekuyedza rinoratidza kuti kana tembiricha yakadzikama yasvika 50 ℃, mwero wekuora kwechiedza cheSMD LED nekukurumidza zvakapetwa katatu kupfuura iyo ye25 ℃ nharaunda, uye hupenyu hunopfupikiswa kusvika 60% yeL70 standard. Kungofanana nekuratidzwa kwenguva refu kuzuva rinopisa, kuita uye hupenyu hweChiedza che LEDtsime richaderedzwa zvikuru.
COB light source
COB inotora matatu-nhanho conduction architecture ye "chip substrate heat sink", ichiwana kusvetuka mumhando yekupisa yekudziya, sekuisa mugwagwa wakafara uye wakafuratira.chiedzazvitubu, zvichibvumira kupisa kukurumidze kuitwa uye kubviswa. Panyaya ye substrate innovation, thermal conductivity yealuminium substrate inosvika 2.0W / m · K, uye iyo yealuminium nitride ceramic substrate inosvika 180W / m · K; Panyaya yemhando yekupisa dhizaini, yunifomu yekupisa layer inoiswa pasi peiyo chip array kudzora mutsauko wekushisa mukati me ± 2 ℃; Iyo inopindirana zvakare nekutonhora kwemvura, ine kupisa kwekupisa simba kunosvika 100W/cm ² apo substrate inosangana nendiro yekutonhodza yemvura.
Mukushandiswa kwemarambi emota, iyo Osram COB mwenje sosi inoshandisa thermoelectric separation dhizaini kudzikamisa tembiricha yekusangana iri pasi pe85 ℃, ichisangana nekuvimbika kwezvinodiwa zveAEC-Q102 mota zviyero, nehupenyu hweanopfuura maawa 50000. Kungofanana nekutyaira nekumhanya kwakanyanya, inogona kuramba ichipa yakagadzikana uyechiedza chakavimbikakuvatyairi, kuve nechokwadi chekuchengetedzwa kwekutyaira.
