LED Specifications: lub teeb emitting diode tsis

Muaj ntau ntau hom LEDs sib txawv uas muaj, txhua hom nrog nws tus kheej cov ntaub ntawv thiab cov lus qhia tshwj xeeb. Txhua yam los ntawm cov xim mus rau lub pob, lub teeb tso zis mus rau qhov poob qis thiab ntau yam kev qhia tshwj xeeb.

Nplooj ntawv no yuav pab nthuav tawm lub ntsiab lus ntawm cov ntaub ntawv tseem ceeb ntawm LED cov ntaub ntawv tshwj xeeb thiab pab coj qee qhov pom tseeb rau kev nkag siab txog LED specifications.

Cov xim tawm los ntawm LED yog teev nyob rau hauv cov nqe lus ntawm nws lub ncov wavelength (lpk) - piv txwv li lub wavelength uas muaj lub ncov lub teeb tso zis. Qhov no yog ntsuas hauv nanometer (nm).

The colour of the LED, i.e. the peak wavelength of the emission from the LED governed mainly by the material used for the LED and also by the chip fabrication process. Variations in the process can tailor the peak wavelength variations up to figures of around ±10nm.

Thaum xaiv cov xim nyob rau hauv tag nrho LED specification, nws yog tsim nyog nco ntsoov tias tib neeg lub qhov muag yog feem ntau rhiab heev rau hue los yog xim variations nyob ib ncig ntawm lub daj / txiv kab ntxwv cheeb tsam ntawm lub spectrum, piv txwv li ntawm li 560 mus 600 nm. Cov txheej txheem me me tuaj yeem ua rau me ntsis xim txawv uas tuaj yeem pom tau yog tias cov txiv kab ntxwv LEDs raug xaiv thiab zaum ntawm ib sab ntawm lub vaj huam sib luag pem hauv ntej. Qhov no yuav cuam tshuam rau kev xaiv xim, lossis txoj haujlwm ntawm LEDs yog tias qhov no tuaj yeem yog teeb meem.

LED teeb pom kev siv lub teeb tsis yog qhov tseem ceeb rau feem ntau cov ntawv qhia, tab sis nrog LEDs siv rau teeb pom kev zoo, qhov ntsuas no yuav tsum muaj peev xwm txheeb xyuas qhov xav tau hauv ntau qhov xwm txheej.

Lub teeb tso zis los ntawm ib qho LED yog xam raws li ib qho taw tes, on-axis luminous siv tus nqi (Iv). Qhov no yog teev raws li millicandella, mcd.

Kev ntsuas lv rau LEDs tsis tuaj yeem yooj yim piv nrog cov txiaj ntsig ntawm lub zog hluav taws xob kheej kheej, MSCP siv rau cov teeb ci.

The luminous intensity value for an LED must be quoted for a given current. Many LEDs will operate at currents of around 20mA, but the light output of an LED increases with increasing current.

LED tam sim no / voltage specification

LEDs are current driven devices and the level of light is a function of the current - increasing the current increases the light output. It is necessary to ensure that the maximum current rating is not exceeded. This could give rise to excessive heat dissipation within the LED chip itself which could result in reduced light output and reduced operating lifetime.

Hauv kev ua haujlwm, LEDs yuav muaj qhov muab hluav taws xob poob hla lawv uas yog nyob ntawm cov khoom siv. Qhov hluav taws xob kuj tseem yuav yog me ntsis nyob ntawm theem tam sim no, yog li qhov tam sim no yuav raug teev rau qhov no.

Feem ntau cov LEDs xav tau ib qho kev sib txuas sab nraud tam sim no txwv cov resistor. Qee cov LEDs yuav suav nrog cov resistor series thiab yuav hais txog qhov kev ua haujlwm tag nrho.

LED rov qab voltage

LEDs tsis kam rau qhov loj rov qab voltages. Lawv yuav tsum tsis txhob khiav saum lawv qhov siab tshaj qhov rov qab voltage, uas feem ntau me me. Yog hais tias lawv yog ces kev puas tsuaj mus tas li ntawm lub cuab yeej yuav luag yeej tshwm sim.

LED kaum sab xis saib specification

Raws li kev pom ntawm txoj kev uas LEDs ua haujlwm, lub teeb tsuas yog tawm ntawm ib lub kaum ntse ntse. Txawm hais tias qhov kev qhia LED no yuav tsis tseem ceeb rau qee qhov kev siv, nws tseem ceeb heev rau lwm tus.

The angle of view is normally defined in degrees - °. For early devices, the angle of view was normally relatively small. More recent devices may have a much wider angle of view.

LED specification rau lub neej ua haujlwm

Lub teeb siv ntawm LED txo qis nrog lub sijhawm. Qhov no txhais tau tias LED muaj lub neej ua haujlwm.

Qhov kev qhia LED no yog qhov tseem ceeb tshwj xeeb thaum LED lossis LEDs yuav tsum tau siv rau kev siv teeb pom kev zoo. Nws tsis yog ib txwm tseem ceeb heev thaum LED siv los ua qhov taw qhia - ntawm no qhov kev puas tsuaj loj yog qhov tseem ceeb dua.

LED specification rau nws lub neej ua hauj lwm feem ntau txhais nyob rau hauv cov nqe lus hauv qab no:

L50%= Lub sij hawm mus rau 50% ntawm illumination (lumen tu)

The rationale behind these figures is that 70% lumen maintenance equates to a 30% reduction in light output. This is around the figure for the threshold for detecting gradual reductions in light output.

Thaum lub teeb tso zis tsis tseem ceeb, 50% lumen txij nkawm daim duab yuav siv tau ntau dua. Txawm li cas los xij rau cov ntawv thov uas lub teeb yuav raug muab tso rau ib sab ntawm qhov sib txawv yuav pom tau zoo heev thiab yog li ntawd 80% lumen txij nkawm daim duab yuav yog qhov siv tau ntau dua.
