Meetso ea Mabone a Kakaretso

Nako: 2020-04-09

Sengoliloeng sena se ngoletsoe ba amehang tikolohong ea mabone, ho kenyeletsa baqapi ba mabone, baetsi ba meralo, baenjiniere, le baetsi ba lisebelisoa tsa mabone.


Mona ke tse ling tsa mabone a akaretsang ao batho ba bangata ba indastering ea khoebo, ea mekhatlo le uyility ba hlokang ho a tseba.


COB (Chips tse ka board)


COB (litebele tse ka sekepeng) ke mahlale a pakang a LED a sebelisoang lienjineng tsa lebone la LED.


Lisebelisoa tsa LED tse ngata li pakiloe hammoho ho liboto tsa substrate tsa LED. Ho na le liboto tsa tšebelisano, liboto tsa aluminium, liboto tsa ceramic joalo-joalo. Har'a likhetho tsena, chip ea board ea Ceramic board e na le ts'ebetso e ntle ho latela ts'ebetso ea mabone le ho fokotsa khanya.


Boholo ba boto bo ka tloha ho mita oa mini ho ea ho lisentimitara tse 'maloa, ho latela bokhoni ba k'hamphani ea nts'etsopele.

SMD


Ma-LED a morao-rao a mahlale a morao-rao ke li-LED tse amehang ka ho fetisisa 'marakeng. Hangata e kentsoe li-PCB tse fapaneng tse bohale ho lekana mabone kapa lisebelisoa tse fapaneng.

Mefuta e tloaelehileng ea SMD ke 2828, 3535, le 5050. Mohlala, 2828 e supa hore bophara ba SMD ke 2.8mm mme bophahamo ke 2.8mm.


Index Rendering Index


Ka linako tse ling mabone a bua leshano. Mmala oa lintho tse ka ntle o fapana le kahare. Ke hobane mabone a na le bokhoni bo fapaneng phetolelong ea mebala.


Index Rendering Index, eo hape e bitsoang CRI, ke tekanyo ea bokhoni ba phetolelo ea mebala. CRI e beha lipalo tse phahameng ho isa ho 100, 'me ha index ea eona e phahama, e ntlafatsa boleng ba mebala.


Bakeng sa merero ea mabone a maiketsetso, sebaka sa CRI sa kantle ke RA70 ho RA80, athe CRI ea kahare ke RA85 ho RA90.Empa bakeng sa libaka tse ikhethang, joalo ka libaka tsa bonto, libaka tsa khatiso, kapa libaka tse fe kapa li fe tse hlokang tlhahiso e mebala e holimo, index ea CRI e ka fihla RA95 ho RA98 kapa hofeta.

mala Mocheso


Mocheso oa mebala ke tekanyo ea hore na leseli le hlahisitsoeng ke lebone le futhumala hakae. Mokhoa oa ho lekanya leseli o feta ka tekanyo ea mocheso oa Kelvin.


Mebala e futhumetseng e shebahala e matahane 'me ka kakaretso e ikutloa e le bonolo ebile e boreleli. Mebala e pholileng e koahetsoe ka boputsoa 'me e shebahala e le tšoeu, e ba etsa' khanya e tšepahalang le e sa tšoareleng, e loketseng maemo a sebetsang ho feta ho phomola.


Ts'ebetso ea Leseli


Khanya ea lebone ke metric e sebelisetsoang ho bapisa karolelano ea tlhahiso ea khanya le tšebeliso ea matla. Yuniti ke lumens ka watt ka ngoe. Sesebelisoa se phahameng sa ho bonesa mabone se bolela ho boloka matla le ho feta ke ts'ebetso ea ho boloka matla.


The lighting efficiency of normal light sources can reach 140lm/w to 160lm/w, while the lighting efficiency of some outstanding models can exceed 180lm/w, which is far away from other lighting equipment.


Leha ho le joalo, ha mohloli oa leseli o kentsoe lebone le etelletsoeng pele, matla a mabone a tla fokotseha hobane ha mabone a feta lense, matla a mabone a tla sebelisoa le ho ananeloa ke 'mele oa tšepe.Le ka lebaka leo mabone a seterateng a sebelisang mehloli ea leseli la LED kamehla .

Lumen


Lumen, the unit of light flow. The lumen rating of a lamp is a measure of the total light output of the lamp. It is used to describe the ability of the light source radiation to produce a strong or weak visual response per unit time. The unit is lumen, also called brightness.


Likhanyo tse ka bang mabone a tloaelehileng (lumens / watt):


* Lebone la Incandescent, 15

* LED e tšoeu, 80-200

* Lebone la Fluorescent, 50

* Leseli la letsatsi, 94

* Lebone la Sodium, 120

* Mabone a pholosang matla, 60-80

* LED, 80-130


* Ka kopo hlokomela hore li-lumens tsena li lekane ebile li ka fapana ka lebaka la bahlahisi ba fapaneng.




Lux


Lux ke yuniti ea leseli, e bonts'ang leseli le bonahala le le bokae holim'a lefatše. Kamore e le 'ngoe e hlalosoa e le leseli le hlahisoang ha lebone le le leng le le teng sebakeng sa mithara se le seng, ka hona, Lux e le ngoe e Lumen ho latela sebaka sa mithara.


Ho bonesa ka letsatsi le khanyang ke li-100,000 tse majabajaba. Papali ea bolo ea maoto e phatlalalitsoeng thelevisheneng e hloka ho bonesoa ka likhahla tse ka bang 16,000. Kichine e hloka li-lux tse ka bang 500. Litsela tsa sechaba bosiu li hloka li-lux tse 30.




Khanya


The degree of illumination required by the surface depends mainly on the type or nature of the sa jobs kapa ketso ya motho emong a bonesitsoe.


Ka hona, mohato oa 1 ke ho fumana hore na leseli le hlokahala hakae. Mofuta oa mosebetsi, nako ea tšebeliso, lilemo le palo ea batho ba sebetsang sebakeng seo, boemo ba mosebetsi hantle, le mabone a tlhaho ke lintho tse hlalosang litlhoko tsa leseli.


Mohato oa bobeli ke ho khetholla palo le mofuta oa mehloli ea leseli e hlokahalang ho hlahisa leseli le lakatsehang. Ho lokela ho nahanoa ka lintlha tse tharo tsa sehlooho.


* Mofuta oa Light source: cost, color and life of the light source are the main determinants of the light source type.


* Matla a bobebe a ketsahalo a latela molao oa lisekoere. Leseli le holim 'a lefatše le lekana le lisekoere tsa sebaka, e leng ho etsang hore sebaka se hole le leseli e be ntho ea bohlokoa.


*Tšebelisano-moho ea tšebeliso le eona ke eona e etsang qeto ea hore na ke bokae ea flux e khanyang e hlile e tsoa mohloling oa leseli holim'a lefatše leo u le batlang. Li-Reflectors, mabone a mabone le mabone li ka eketsa kapa tsa fokotsa ts'ebeliso. Sekhahla sa tšebeliso ea mabone a liindasteri a matle se ka fihla ho 90%.



LED Array kapa Module


In the assembly of LED package (components) or dies on a printed circuit or substrate, the optical element may have additional thermal, mechanical, and used to connect an electrical load to the LED drive interface side. The device has no power supply and standard lamps. The device cannot be directly connected to the branch circuit.


It may carry optical components and other thermal, mechanical, and electrical interfaces that are intended to connect to the load side of the LED driver.
