2. In-depth Analysis of Technical Parameters

Sehemu hii inatoa tafsiri ya kina na ya uwazi ya vigezo muhimu vya kiufundi vilivyoorodheshwa kwenye hati ya maelezo. Kuelewa viwango hivi vya juu na sifa ni muhimu kwa usanifu sahihi wa saketi na uendeshaji thabiti.

2.1 Viwango vya Juu Kabisa

Viwango hivi vya kudumu vinabainisha mipaka ya mkazo ambayo inaweza kusababisha uharibifu wa kudumu wa kifaa. Haipendekezwi kuendesha kwa muda mrefu chini ya hali zinazokaribia au kufikia mipaka hii.

• Continuous Forward Current (I_F):25 mA. This is the maximum direct current that can be continuously applied without degrading the LED's performance or lifespan. Exceeding this value increases junction temperature and accelerates lumen depreciation.
• Peak Forward Current (I_FP):60 mA (duty cycle 1/10, frequency 1 kHz). This rating allows brief current pulses, which can be used for multiplexing or achieving higher instantaneous brightness. The 10% duty cycle is critical; the average current must still comply with the continuous rating.
• Reverse Voltage (V_R):5 V. The LED is not designed to withstand significant reverse bias. Applying a reverse voltage exceeding 5V will cause immediate and catastrophic failure due to junction breakdown.
• Power Dissipation (P_d):60 mW. Hii ndiyo nguvu ya juu ambayo kifurushi kinaweza kutawanya kwa namna ya joto. Fomula ya kuhesabu ni voltage ya mbele (V_F) * sasa ya mbele (I_F). Wabunifu lazima wahakikisha sehemu ya uendeshaji haizidi kikomo hiki.
• Halijoto ya uendeshaji na uhifadhi:-40°C to +85°C (operating), -40°C to +100°C (storage). The wide temperature range makes it suitable for industrial and automotive environments (non-critical areas).
• Soldering temperature:260°C for 5 seconds. This defines the tolerance for the reflow soldering temperature profile, which is crucial for PCB assembly without damaging the epoxy or internal bonding wires.

2.2 Photoelectric Characteristics (Ta=25°C)

These are typical performance parameters measured under standard test conditions (forward current 20mA, ambient temperature 25°C).

• Luminous Intensity (I_v):Typical value 16 mcd, minimum value 10 mcd. This specifies the amount of visible light emitted in a given direction. The minimum value is the guaranteed lower limit for product acceptance. In designs with strict tolerance requirements, a measurement uncertainty of ±10% should be considered.
• Viewing Angle (2θ_1/2):Typical value 170 degrees. This very wide viewing angle indicates the use of a diffuser lens/resin, producing a broad, uniform illumination pattern rather than a narrow beam. It is an ideal choice for LED applications requiring visibility from multiple angles.
• Peak Wavelength (λ_p):Thamani ya kawaida 632 nm. Hii ndio urefu wa wimbi ambapo usambazaji wa nguvu ya wigo unafikia thamani ya juu zaidi. Inafafanua "rangi" ya mwanga unaotolewa na chip ya semiconductor yenyewe.
• Urefu wa wimbi mkuu (λ_d):Thamani ya kawaida 624 nm. Hii ndio urefu wa wimbi wa mwanga mmoja ambao jicho la binadamu linaona na unalingana na rangi ya LED. Kwa maelezo ya rangi, kwa kawaida ni muhimu zaidi kuliko urefu wa wimbi wa kilele. Tafadhali kumbuka kutokuwa na uhakika wa kipimo cha ±1.0nm.
• Upana wa mionzi ya wigo (Δλ):Thamani ya kawaida 20 nm. Hii ni upana wa wigo kwenye nusu ya kilele (FWHM). Thamani ya 20nm ni sifa ya LED nyekundu ya AlGaInP, ikionyesha kuwa ina usawa wa rangi safi kiasi.
• Voltage ya mbele (V_F):Thamani ya chini 1.7V, thamani ya kawaida 2.0V, thamani ya juu 2.4V (chini ya I_F=20mA). Hii ni kushuka kwa voltage kwenye ncha za LED inapofanya kazi. Muundo wa saketi ya kuendesha lazima ufanane na anuwai hii. Kutokuwa na uhakika wa kipimo cha ±0.1V kimebainishwa katika vipimo.
• Sasa ya nyuma (I_R):Upeo wa juu 10 μA (chini ya hali ya V_R=5V). Hii ni mkondo wa uvujaji wakati kifaa kiko katika upendeleo wa nyuma. 10μA ni thamani ya kawaida kwa LED ya kiashiria.

2.3 Thermal Characteristics

Ingawa haijaorodheshwa wazi kwenye jedwali tofauti, umuhimu wa usimamizi wa joto unaweza kudhaniwa kupitia viwango vya nguvu na anuwai ya halijoto ya uendeshaji. Mkunjo wa utendaji unaonyesha utegemezi wa pato la mwanga na mkondo wa mbele kwenye halijoto ya mazingira, ambayo ni kipengele muhimu cha muundo. Wakati wa kufanya kazi katika halijoto ya juu ya mazingira, upoaji wa joto unaofaa au kupunguzwa kwa mkondo kunahitajika ili kudumisha utendaji na maisha ya huduma.

3. Grading System Description

Buku ya maelezo inataja mfumo wa kugawanya daraja kwa vigezo muhimu, kama ilivyoonyeshwa kwenye lebo ya nyenzo za ufungaji. Kugawanya daraja ni mchakato wa kuainisha LED katika makundi (daraja) kulingana na utendaji uliopimwa, ili kuhakikisha uthabiti ndani ya kundi moja la uzalishaji.

• CAT (Luminous Intensity Bin):LEDs are binned according to measured luminous intensity (e.g., 10-12 mcd, 13-15 mcd, 16-18 mcd). This allows designers to select the appropriate brightness grade for their application.
• HUE (Dominant Wavelength Bin):LEDs are binned according to dominant wavelength (e.g., 622-624 nm, 624-626 nm). This ensures color consistency among multiple LEDs used within a single product.
• REF (Forward Voltage Bin):Forward voltage is also binned (e.g., 1.9-2.1V, 2.1-2.3V). This is important for designs with multiple LEDs in series, as it affects the total voltage requirement in series configuration and current matching in parallel configuration.

The specific bin code ranges are not detailed in this public specification. They are typically defined in a separate binning document or negotiated during the ordering process.

4. Performance Curve Analysis

The provided charts offer valuable information for understanding the device's behavior under non-standard conditions.

4.1 Uhusiano wa Nguvu ya Mwanga ya Jamaa na Wavelength

Mkunjo huu wa usambazaji wa wigo unathibitisha urefu wa wimbi wa kilele cha kawaida cha takriban 632 nm na upana wa nusu ya kilele cha takriban 20 nm, ambayo ni sifa ya LED nyekundu angavu ya AlGaInP. Umbo lake ni la kawaida, lenye kukatika kwa mwinuko upande wa urefu wa wimbi mrefu na kupungua kwa mpole zaidi upande wa urefu wa wimbi mfupi.

4.2 Mchoro wa Usambazaji wa Mwelekeo

The polar plot shows a viewing angle of 170 degrees. The luminous intensity is nearly uniform across a very wide area, confirming the diffusing characteristics of the lens. There are no significant side lobes or narrow hot spots, which is ideal for wide-angle indicator light applications.

4.3 Uhusiano wa Sasa ya Mwelekeo na Voltage ya Mwelekeo (I-V Curve)

Grafu hii inaonyesha uhusiano wa kielelezo wa diode ya kawaida. Voltage ya "kigeuzo" ambapo LED inaanza kufanya kazi kwa kiwango kikubwa ni takriban 1.6V. Katika mkondo unaopendekezwa wa uendeshaji wa 20mA, voltage ya mbele ni takriban 2.0V. Mkunjo huu ni muhimu sana kwa kubuni kichocheo cha mkondo wa mara kwa mara au mzunguko rahisi wa kudhibiti mkondo unaotegemea upinzani.

4.4 Relationship Between Relative Light Intensity and Forward Current

Pato la mwanga (nguvu ya mwanga ya jamaa) huongezeka kwa mstari kadri mkondo wa mbele unavyoongezeka, hadi kufikia kiwango cha juu cha kawaida. Uhusiano huu wa mstari unarahisisha udhibiti wa mwangaza kupitia udhibiti wa mkondo (kupunguza mwanga kwa analogi). Hata hivyo, katika mikondo ya juu sana, ufanisi unaweza kupungua kwa sababu ya athari za joto zinazozidi.

4.5 相对光强与环境温度关系 & 正向电流与环境温度关系

Hizi ni mikondo ya kupunguza mzigo, ambayo inaweza kusemwa kuwa ni sehemu muhimu zaidi katika usanifu wa kuaminika.

• Uhusiano wa Pato la Mwanga na Joto:Ukubwa wa jamaa wa mwanga hupungua kadri halijoto ya mazingira inavyoongezeka. Kwa mfano, kwenye 85°C, pato la mwanga linaweza kuwa takriban 70-80% tu ya ile kwenye 25°C. Katika matumizi yanayohitaji uthabiti wa mwangaza kwenye anuwai ya halijoto, hii lazima ilipwe fidia.
• Kwa ufungaji wa LED wa radial, cathode kawaida hutambuliwa kupitia uso uliopigwa kwenye ukingo wa lenzi ya plastiki, pini fupi, au nafasi kwenye flange. Njia maalum ya utambuzi inapaswa kuonyeshwa kwenye mchoro wa vipimo vya ufungaji. Uwiano sahihi ni muhimu sana; voltage ya nyuma inayozidi 5V inaweza kuharibu kifaa.Mkunjo huu unaweza kuonyesha upeo wa ruhusiwa wa mkondo wa mbele kama utendakazi wa joto la mazingira ili kudumishwa ndani ya mipaka ya matumizi ya nguvu. Kwa uhakika wa kutegemewa, mkondo wa uendeshaji lazima upunguzwe (kupunguzwa kwa rating) kadiri joto la mazingira linavyoongezeka. Ni salama tu kukimbia kwa mkondo wa juu kabisa wa 25mA katika hali ya joto la chini la mazingira.

5. Mechanical and Packaging Information

5.1 Package Size

LED hii inatumia ufungaji wa kawaida wa waya wa radial (kwa kawaida huitwa "3mm" au "T1", lakini vipimo halisi vinapaswa kuwa kulingana na mchoro). Maelezo muhimu ya vipimo ni pamoja na:

• Vipimo vyote vina kipimo cha milimita.
• Urefu wa flange (makali ya chini ya kuba) lazima uwe chini ya 1.5mm (0.059"). Hii ni muhimu kwa nafasi wakati wa kusanikisha kwenye PCB.
• Toleo la kawaida la vipimo visivyoonyeshwa ni ±0.25mm.

Mchoro wa vipimo ni muhimu sana kwa muundo wa PCB pad, kuhakikisha umbali sahihi wa mashimo na uwekaji wa vipengele.

5.2 Polarity Identification

For radial LED packages, the cathode is typically identified by a flat spot on the rim of the plastic lens, a shorter lead, or a notch in the flange. The specific identification method should be indicated on the package dimension drawing. Correct polarity is essential; reverse biasing beyond 5V can destroy the device.

6. Welding and Assembly Guide

Kuzingatia miongozo hii kwa uangalifu ni muhimu ili kuzuia uharibifu wa mitambo na joto wakati wa usanikishaji.

6.1 Lead Forming

• Pindua pini kwa umbali wa angalau 3mm kutoka chini ya taa ya epoxy.
• Operesheni ya kuunda piniLazima iwe soldering.
• Perform before soldering. Avoid applying stress to the LED package during the forming process. Stress may cause epoxy cracking or damage to internal bonding wires.
• Cut the leads at room temperature. High-temperature cutting may cause thermal shock.
• Hakikisha mashimo ya PCB yanalingana kikamilifu na pini za LED, ili kuepuka mkazo wa usakinishaji.

6.2 Storage Conditions

• Baada ya kupokea, tafadhali hifadhi chini ya hali ya joto ≤30°C na unyevu wa jamaa ≤70%.
• Maisha ya uhifadhi kwenye mfuko asilia: miezi 3.
• Kwa uhifadhi wa muda mrefu zaidi (hadi mwaka 1): tafadhali tumia chombo kilichotiwa nitrojeni na kifungo cha ukaushaji.
• Epuka mabadiliko ya ghafla ya joto katika mazingira yenye unyevunyevu ili kuzuia umande.

6.3 Welding Process Parameters

Kanuni za Jumla:Weka umbali wa chini wa mm 3 kati ya mwamba wa kuunganishia na taa ya LED ya epoxy.

Uchomeaji kwa Mkono:

• Joto la ncha ya chuma cha kuchomelea: hadi 300°C (nguvu ya chuma cha kuchomelea hadi 30W).
• Muda wa kulehemu: sekunde 3 kwa kila pini.

Wave soldering (DIP):

• Joto la kukausha: Hadi 100°C (kwa muda wa sekunde 60 kwa kiwango cha juu).
• Joto la chombo cha kuuza bati na muda: Hadi 260°C, kwa muda wa sekunde 5 kwa kiwango cha juu.

Uangalizi Muhimu:

• Epuka kutumia mkazo kwenye pini wakati LED iko katika hali ya joto kali.
• Usifanye uuzaji wa kupitishia umeme zaidi ya mara moja (soldering by dipping au manual soldering).
• Baada ya kulehemu, linda LED kutokana na mshtuko/utetendaji wa kikabla kabla ya kupoa hadi joto la kawaida.
• Punguza joto polepole kutoka kiwango cha juu; kupoa kwa kasi hakupendekezwi.
• Daima tumia joto la chini kabisa linalowezekana la kulehemu linalofanikisha muunganisho wa kuaminika.

6.4 Cleaning

• Ikiwa ni lazima, tumia isopropanol kwa usafishaji tu kwa joto la kawaida la chumba, kwa muda usiozidi dakika moja.
• Kukausha hewani kwenye joto la kawaida.
• Isipokuwa uthibitisho umekamilika mapema chini ya hali maalum.Usitumie usafishaji wa mawimbi ya sauti (ultrasonic) kwani unaweza kuharibu muundo wa ndani.

7. Ufungaji na Taarifa za Kuagiza

7.1 Vipimo vya Ufungaji

Ufungaji wa LED unakusudiwa kuzuia utokaji umeme tuli (ESD) na kuingia kwa unyevu:

1. Ufungaji wa kiwango cha kwanza:Mfuko wa kuzuia umeme wa tuli, wenye angalau vipande 200 hadi 1000.
2. Ufungaji wa kiwango cha pili:4 anti-static bags are placed into one inner box.
3. Tertiary packaging:10 inner boxes are placed into one master carton.

7.2 Labeling Instructions

Lebo ya mfuko wa ufungashaji ina misimbo kadhaa inayotumika kufuatilia na kutambua vipimo:

• CPN:Customer Production Number (optional customer reference number).
• P/N:Production Number (manufacturer part number, e.g.: 594SURD/S530-A3).
• QTY:Idadi ya vifurushi ndani ya mfuko.
• CAT, HUE, REF:They are the binning codes for luminous intensity, dominant wavelength, and forward voltage, respectively.
• LOT No:Production lot number, used for traceability.

8. Application Design Considerations

8.1 Drive Circuit Design

The most common driving method is to connect a current-limiting resistor in series. The formula for calculating the resistor value (R) is: R = (V_{Power Supply}- V_F) / I_F. Use the maximum V_Fvalue (2.4V) from the datasheet for calculation to ensure reliability even with a low V_FThe LED current will not exceed the desired value. For example, using a 5V power supply with a target I_Fof 20mA: R = (5V - 2.4V) / 0.02A = 130Ω. The closest standard value (120Ω or 150Ω) should be selected, with 150Ω being more conservative. For critical applications requiring high brightness uniformity or a wide operating temperature range, the use of a constant current driver is recommended.

8.2 Thermal Management

Even for small indicator LEDs, thermal management is still important for extending lifespan. Ensure the PCB has sufficient copper foil area around the LED pins to act as a heat sink. Avoid placing LEDs near other heat-generating components. When designing for high ambient temperature environments, adhere to the current derating guidelines shown in the performance curves.

8.3 ESD (Electrostatic Discharge) Protection

Spec sheet inabainisha kuwa bidhaa hii ni nyeti kwa ESD. Katika mchakato wa usanikishaji, lazima kufuata tahadhari za kawaida za usindikaji wa ESD: tumia kituo cha kazi kilichowekwa ardhini, mkanda wa mkono, na mto wa sakafu unaoendesha umeme. Safirisha na hifadhi kwenye mfuko wa kinga ya ESD.

9. Maswali Yanayoulizwa Mara kwa Mara (Kulingana na Vigezo vya Kiufundi)

9.1 Naweza kutumia kiwango cha mantiki cha 3.3V kuendesha LED hii?

Yes. Use a series resistor: At a typical V_FWhen it is 2.0V, the required resistance value is (3.3V - 2.0V)/0.02A = 65Ω. However, if the LED's maximum V_Fis 2.4V, then with a 3.3V power supply and a 65Ω resistor, the current will be only about 14mA, resulting in reduced brightness. A smaller resistor (e.g., 47Ω) can be used, but it must be verified that the current does not exceed 25mA under the minimum V_F conditions.

The current does not exceed 25mA under the conditions.

9.2 Kwa nini pembe ya kuona ni pana kiasi hiki (170°)?

Maelezo ya resin "SURD" na "Red Diffused" katika nambari ya sehemu yanaonyesha kuwa inatumia lenzi iliyotawanyika. Hii hutawanya mwanga, na kutoa pembe ya kuona pana sana na sawasawa, inayofaa kabisa kwa taa za kiashiria cha hali zinazohitaji kuonekana kutoka pande nyingi (sio tu mbele moja kwa moja).

9.3 Je, kuna tofauti gani kati ya Peak Wavelength (632nm) na Dominant Wavelength (624nm)?

Urefu wa wimbi la kilele ndio kilele cha kimwili cha wigo wa mwangaza unaotolewa na chip. Urefu wa wimbi kuu ndio "nukta ya rangi" inayohisiwa na jicho la binadamu, ambayo huathiriwa na umbo la wigo mzima na usikivu wa jicho (majibu ya kuona mwanga). Kwa matumizi ya kuendana rangi, urefu wa wimbi kuu kwa kawaida huwa muhimu zaidi.

9.4 Ni LED ngapi ninaweza kuunganisha mfululizo?_FKikomo kinategemea voltage yako ya kuendesha. Kwa kiendesha cha mkondo wa mara kwa mara, ongeza V

Kuongeza. Kwa mfano, kwa kutumia kiendeshi cha 12V: 12V / 2.4V = LED nyingi zaidi 5 zinaweza kuunganishwa mfululizo. Daima weka nafasi ya ziada. Kwa mfululizo wa LED unaoendeshwa na chanzo cha voltage kupitia upinzani, hesabu ni ngumu zaidi; ni lazima kuzingatia jumla ya kupungua kwa voltage na mkondo.
