LED ea SMD KE ENG?

Lisebelisoa tsa holim'a metsi, li-Diode tse khanyang

LED ea SMD ke chip e nyane haholo ebile e bobebe e koetsoeng ka lehoakhoa la epoxy.

Tsena li fana ka khanya e fetelletseng ha li ntse li boloka tšebeliso e tlase ea matla ha li bapisoa le mofuta o mong oa bulbs (mohlala. Incandescent).

Ka kakaretso motlakase o hloka ka SMD ea LED e ka bang 2 - 3.6V *, 0.02A-0.03A. Ka hona e na le litlhoko tse tlase haholo tsa motlakase le matla.

Ts'ebeliso ea matla ha e bapisoa le litleloubu, e sebelisoa ho 1 / 8th. Maemong a phethahetseng, tebello ea bophelo e kanna ea fihla ho lihora tse 100,000.

Li-SMD tse tsebahalang haholo, ke lihlahisoa no.s 3528 le 5050.

SMD 3528 ke sephutheloana se le seng se hlahisang khanya, ha SMD 5050 e le ka har'a sephutheloana sa khanya e meraro.

3528 e bitsoa joalo ho hlalosa litekanyo tsa chip (35x28mm), ha ts'ebeliso ea eona e ka ba 12V * 0.08W / chip.

Ho fapana le hoo, litekanyo tsa SMD 5050 ke 50x50mm, 'me tšebeliso ea eona ea matla ke 12V * 0.24W / chip.

Ka khopolo 5050 SMD e feta makhetlo a 3 ho feta 3528.

 

* Tlhokomeliso: ha re ntse re re 12V, leha ho le joalo re hlalositse kaholimo hore ke 2-3,6V ka SMD.

Kahoo ka theipi ea LED ea SMD re ke ke ra matlafatsa tlase ho li-SMD tse 3 (4x3smd = 12V)

 

Melemo:

Ho boloka matla ka kotloloho ka lebaka la ts'ebeliso e tlase.

Emittion ea mocheso o tlase.

Ha ho na tlhoko ea tlhokomelo ka lebaka la tebello ea bophelo e kholo haholo (ka hona litšenyehelo tse tlase tsa ho sebetsa).

Leseli le lesoeu le ntlafatsa mebala ea 'nete ea lihlahisoa tsa hau tse hlahang.

Li-SMD tse sebelisoang ke UNIKE li tsoa mefuteng e tummeng ea machabeng Lumileds, CREE, Osram e nang le boleng bo tsitsitseng, ts'epahalo le ts'ebetso. Hajoale, Lumileds 2835SMD, 3030SMD le 5050SMD li sebelisoa haholo. Mocheso oa 'mala ke 3000K / 4000K / 5000K / 5700K / 6500K e fumanehang,' me CRI e khetha 70/80 / 90Ra. Bokhabane bo khanyang ba lebone lohle bo fihletse katleho e phahameng e khanyang ea 170lm / Watt. Bophelo ba lebone bo ka ba bolelele ba lihora tse 100,000. UNIKE e hlokometse haholo mabone a tala, a sebetsang hantle haholo, a bolokang matla le a bolokang tikoloho.
