Ho na le mefuta e mengata e fapaneng ea likhoele tsa LED, e 'ngoe le e' ngoe e na le likarolo tsa eona tse ikhethang. Sehloohong sena, re tla buisana ka lesela le khanyang ka ho fetisisa la LED 'marakeng.
Leseli la LED le khanyang ka ho fetisisa 'marakeng ke lefe?
Ke li-strip tsa LED tsa SMD2835 tse sebetsang hantle haholo, 9LED ka sehiloeng, CRI> 80, ho feta 220LM/W, mme matla a ka feta 20W/M. Ba sebelisa khanya e phahameng ea SMD2835 LED e nang le chip ea boholo bo boholo, koporo e hloekileng ea 3OZ kapa 4OZ PCB.
Khanya ea likhoele tsa LED e khethoa ke lumens.
Lumens = Leseli Leseli. Ka mantsoe a bonolo, Lumens (e hlalosoang ke lm) ke tekanyo ea kakaretso ea khanya e bonahalang (ka leihlo la motho) e tsoang leboneng kapa mohloling oa leseli.
Lintlha tse amang lumens ea likhoele tsa LED.
Lintlha tse peli tse kholo li ama lumens ea lihlopha tsa LED, khanya e khanyang (lm / w) le matla (w / m). Joalo ka ha re tseba, li-lumens tsa lesela la LED li lekana le ts'ebetso e khanyang e atolositsoeng ke matla.
Leseli bokgoni
Matla a khanyang ke tekanyo ea hore na mohloli oa leseli o hlahisa khanya e bonahalang hantle hakae. Ke karo-karolelano ea phallo e khanyang ho matla, e lekantsoeng ka lumens ka watt (lm/w).
Lintlha tse ka sehloohong tse amang ts'ebetso ea khanya ke tse latelang:
Boholo ba Chip ea LED
Lifaha tsa mabone a LED ke likarolo tse ntšang khanya, 'me likarolo tsa tsona tse ka sehloohong ke li-chips, li-brackets le lithapo tsa khauta tse kopanyang li-chips le masakana. Karolo e ka ntšang leseli ke chip. Ka hona, boholo ba chip bo lekanya bokhoni bo khanyang ba lifaha tsa lebone la LED. Ha boholo ba chip bo le boholo, bo eketsa bokhoni bo khanyang ba lifaha tsa lebone la LED. Ho na le lifeme tsa lifaha tsa mabone 'marakeng. Ho ntlafatsa ts'ebetso e khanyang le ts'epahalo ea lifaha tsa lebone tse tšoeu tsa SMD2835 LED, li-chips tse peli li kenngoa ka har'a bracket.
CRI
A index ea tlhahiso ea mebala (CRI) ke tekanyo ea palo ea bokhoni ba mohloli oa leseli ho senola mebala ea lintho tse sa tšoaneng ka botšepehi ha ho bapisoa le mohloli oa khanya oa tlhaho kapa o tloaelehileng.
CRI e boetse ke ntlha ea bohlokoa ho khethollang katleho e khanyang. Ha CRI e phahame, e theola bokhoni bo khanyang.
Haeba u batla ho tseba lintlha tse ling, ka kopo bala Hobaneng ha CRI e Phahameng e lula e sa sebetse hantle.
CCT
Thempereichara ea 'mala (Correlated Color Temperature, kapa CCT, in lighting tech jargon) ha e le hantle ke tekanyo ea hore na 'mala o mosehla kapa o moputsoa oa leseli o tsoang mohloling o hlaha hakae. E lekantsoe ka yuniti ea Kelvin 'me hangata e fumanoa lipakeng tsa 2200 Kelvin degrees le 6500 Kelvin degrees.
Ka kakaretso, ha CCT e phahame, e phahamisa matla a khanya. Ka mohlala, bakeng sa sefaha sa lebone sa lebone sa LED se tšoanang, katleho e khanyang ea 6000K e phahame ho feta ea 2700K.
matla
Ha khanya e sebetsang hantle e tiile, matla a phahameng a phahame, a phahamisa lumen.
Kahoo, haeba re hloka khanya e phahameng, re hloka ho eketsa matla.
Matla a lesela la LED a angoa haholo ke lintlha tse latelang:
Lebokose la LED
Sefaha se le seng sa lebone sa LED se na le moeli o phahameng oa hajoale. Ka mohlala, SMD2835 e tloaelehileng ke 60mA, 'me SMD3528 ke 20mA. Haeba re batla ho eketsa matla a lesela la LED, re hloka ho eketsa bongata ba lifaha tsa lebone la LED.
Tlhokomeliso: Ho boloka litšenyehelo, bahlahisi ba bang ba theha masela a LED a nang le motlakase o fetang tekanyo e holimo ea libaha tsa lebone la LED. Leha ho le joalo, ha lesela lena la LED le sebetsa, mocheso o tebile, 'me ka mor'a nako e itseng, khanya e tla fokotseha.
PCB
PCB ke karolo e 'ngoe ea bohlokoa. Mosebetsi oa eona o ka sehloohong ke ho hokahanya likarolo tse kang mabone a lebone la LED le li-resistors.
Karolo e ka sehloohong ea PCB ke koporo, 'me palo ea koporo e etsa qeto ea hore na PCB e sebetsa joang. Koporo e teteaneng, e sephara e ka feta hona joale mme ea hlahisa mocheso o fokolang.
PCBs ka boela thusa dissipate mocheso kapele. Mocheso o bohlokoa bophelong ba LED, 'me mocheso o phahameng o ka fokotsa bophelo ba LED.
Ka hona, ho eketsa matla a lesela la LED, re tlameha ho khetha PCB e nang le koporo e hloekileng le e pharaletseng haholoanyane.
Aluminium Profile
Matla a mangata a bolela mocheso o mongata. Leha ho le joalo, haeba mocheso o sa felisoe ka nako, o tla fokotsa bophelo ba LED. E 'ngoe ea litsela tse atileng haholo tsa ho thusa ho qhala mocheso ka potlako ke ho hokela likhoele tsa LED ho lintlha tsa aluminium.
