smd light strip e bolela'ng?

Ka botumo ba mohopolo oa moralo oa "no main light light", lihlahisoa tsa linear light strip tsa LED li ntse li tsebahala le ho feta molemong oa mekhabiso ea lapeng le merero ea ho etsa ntlo eohle. Ho na le lihlahisoa tse tharo tse tloaelehileng tsa mabone a LED 'marakeng, e leng likhoele tsa mabone a SMD LED, likhoele tsa mabone a COB LED le likhoele tsa morao-rao tsa CSP LED. Le hoja sehlahisoa se seng le se seng se na le melemo le liphapang tsa sona, mohlophisi o tla leka ho sebelisa sehlooho se le seng ho u lumella ho utloisisa phapang pakeng tsa tse tharo, e le hore u ka etsa khetho e nepahetseng.

Li-strip tsa mabone a SMD, lebitso le felletseng la lisebelisoa tse khanyang tsa Surface Mounted Devices (Surface Mounted Devices), li bua ka chip ea LED e kentsoeng ka kotloloho holim'a substrate ea leseli, ebe e phutheloa ho etsa mela e menyenyane ea mabone. Mofuta ona oa leseli ke mofuta o tloaelehileng oa lebone la lebone la LED, leo hangata le nang le litšobotsi tsa ho feto-fetoha ha maemo, bosesaane, ho boloka matla le bophelo bo bolelele.

SMD ke khutsufatso ea "Surface Mount Device", e leng mofuta o atileng haholo oa sesebelisoa sa LED hajoale 'marakeng. Chip ea LED e kentsoe ka har'a khetla ea bracket ea LED ka sekhomaretsi sa phosphor ebe e beoa holim'a boto ea potoloho e hatisitsoeng (PCB). Li-strip tsa LED tsa SMD li tumme haholo ka lebaka la ho feto-fetoha ha tsona. , Lisebelisoa tsa LED tsa SMD li na le boholo bo sa tšoaneng: 3528, 5050, 2835, 3014, 2216, 2110; ka kakaretso li bitsoa ho latela boholo ba tsona, mohlala, boholo ba 3528 ke 3.5 x 2.8mm, 5050 ke 5.0 x 5.0mm, le 2835 ke 2.8 x 3.5mm, 3014 ke 3.0 x 1.4mm.

Kaha likhoele tse tloaelehileng tsa SMD LED li sebelisa likarolo tse arohaneng tsa SMD LED, sebaka / lekhalo lipakeng tsa lisebelisoa tse peli tse haufi tsa LED li batla li le kholo. Ha leselinyana le khantšitsoe, u ka bona lintlha tse khanyang ka bomong. Batho ba bang ba re Bakeng sa libaka tse chesang kapa tse hlahelletseng. Kahoo haeba u sa batle ho bona matheba a chesang kapa matheba a khanyang, u lokela ho sebelisa thepa e koahelang (e kang sekoahelo sa polasetiki) ho e beha ka holim'a lesela la LED la SMD, 'me u lokela ho siea bophahamo bo lekaneng bakeng sa ho kopanya leseli ho khaola. matheba a khanyang Letheba le khanyang, ka hona, profilse ea aluminium e sebelisoang hangata e teteaneng.

Leseli le khanyang la COB, lebitso le felletseng ke Leseli la lebone la LED la Chips On Board, ke mofuta oa lebone la lebone la LED le nang le chip on board (Chips On Board). Ha ho bapisoa le likhoele tsa mabone a SMD, likhoele tsa mabone a COB li paka ka kotloloho li-chips tse ngata tsa LED holim'a boto ea potoloho ho theha sebaka se seholo se ntšang khanya, seo hangata se sebelisoang maemong a ts'ebeliso a hlokang mabone a tšoanang.

Ka lebaka la sekhomaretsi sa phosphor se sa khaotseng, likhoele tsa COB LED li ka hlahisa leseli le ts'oanang ntle le letheba le le leng le hlakileng, kahoo li ka hlahisa leseli le ntšang khanya ka mokhoa o tsitsitseng ntle le tlhoko ea likoahelo tse eketsehileng tsa polasetiki. , haeba u ntse u hloka ho sebelisa lijana tsa aluminium, u ka khetha profiles tse tšesaane haholo tsa aluminium tse bataletseng.

CSP ke e 'ngoe ea litheknoloji tsa morao-rao indastering ea LED. Indastering ea LED, CSP e bua ka foromo e nyane le e bonolo ka ho fetisisa ea sephutheloana ntle le substrate kapa terata ea khauta. Ho fapana le thekenoloji ea boto ea khanya ea SMD, CSP e sebelisa liboto tsa potoloho tse feto-fetohang tsa FPC.

FPC ke mofuta o mocha oa mohala o entsoeng ka filimi e sireletsang le terata ea koporo e tšesaane haholo, e hatelloang hammoho ka mohala oa tlhahiso ea thepa ea laminating e ikemetseng. E na le melemo ea ho ba bonolo, ho kobeha le ho phutha mahala, botenya bo tšesaane, boholo bo nyane, ho nepahala ho phahameng, le conductivity e matla.

Ha ho bapisoa le sephutheloana sa setso sa SMD, sephutheloana sa CSP se na le ts'ebetso e bonolo, lisebelisoa tse tlase, litšenyehelo tse tlase, 'me sekhutlo se hlahisang leseli le tataiso li kholo ho feta mefuta e meng ea liphutheloana. Ka lebaka la boikhethelo ba ts'ebetso ea eona ea ho paka, masela a mabone a CSP a ka ba nyane, a bobebe le a bobebe, 'me a ba le lintlha tse nyane tse kobehang. Ka nako e ts'oanang, lehlakoreng la eona la ho ntša leseli le leholo, le fihla ho 160 °, 'me' mala o khanyang o hloekile ebile o bonolo, ha o na mahlakore a mosehla. Karolo e kholo ka ho fetisisa ea likhoele tsa mabone a CSP ke hore ha li bone leseli 'me li bonolo ebile li lerootho.
