2. In-depth Technical Parameter Analysis

2.1 Absolute Maximum Ratings

Absolute maximum ratings define the stress limits that may cause permanent damage to the device. These values are not intended for normal operating conditions. For the 17-215 LED, the maximum continuous forward current (I_F) rating is 25 mA. Under pulsed conditions with a duty cycle of 1/10 and a frequency of 1 kHz, the peak forward current (I_FP) Inaweza fikia 60 mA. Upeo wa voltage ya kurudia inayoruhusiwa (V_R) ni 5 V; ni muhimu kuzingatia kuwa kifaa hiki hakikusudiwa kufanya kazi kwa upendeleo wa kurudia, rating hii inatumika hasa kwa hali ya majaribio ya mkondo wa kurudia (I_R). Jumla ya matumizi ya nguvu (P_d) haipaswi kuzidi 60 mW, thamani hii inakokotolewa kutokana na bidhaa ya voltage ya mbele na mkondo wa mbele. Kulingana na mfano wa mwili wa binadamu (HBM), kifaa hiki kinaweza kustahimili utokaji umeme tuli (ESD) wa 2000 V. Safu ya joto ya uendeshaji (T_opr) is -40°C to +85°C, while the storage temperature (T_stg) is slightly wider, up to +90°C.

2.2 Electro-Optical Characteristics

Photoelectric performance is specified under standard test conditions with an ambient temperature (T_a) of 25°C and a forward current of 20 mA. The typical range of luminous intensity (I_v) is from 36.00 mcd to 72.00 mcd, with a specified tolerance of ±11%. The spatial distribution of light features a wide viewing angle (2θ_1/2) as a feature, providing broad illumination. The spectral characteristics are defined by the peak wavelength (λ_p) 575 nm and the dominant wavelength (λ_d) range 570.00 nm to 574.50 nm (tolerance ±1nm). The spectral bandwidth (Δλ) is approximately 20 nm. At a current of 20 mA, the forward voltage (V_FThe typical range for ) is 1.75 V to 2.35 V, with a tolerance of ±0.1 V. When a 5 V reverse voltage is applied, the reverse current (I_R) is guaranteed to be less than or equal to 10 μA.

3. Maelezo ya Mfumo wa Kupanga

To ensure consistency in mass production, LEDs are sorted into different bins based on key performance parameters. This allows designers to select components that meet the requirements of specific applications in terms of brightness, color, and electrical behavior.

3.1 Luminous Intensity Binning

Nguvu ya mwanga imegawanywa katika vikundi vitatu kuu_Fchini ya hali ya I = 20 mA:

4. Performance Curve Analysis

Ingawa faili ya PDF inaonyesha kuwa ukurasa wa 5 una mkunjo wa kawaida wa sifa za optoelektroniki, maudhui ya maandishi hayatoi chati maalum. Kwa kawaida, maelezo kama haya ya vipimo yanajumuisha mikunjo inayoonyesha uhusiano kati ya sasa ya mwelekeo mzuri na ukubwa wa mwanga, uhusiano kati ya voltage ya mwelekeo mzuri na sasa ya mwelekeo mzuri, na ukubwa wa jamaa wa mwanga unavyobadilika kulingana na joto la mazingira. Mikunjo hii ni muhimu sana kwa wabunifu kuelewa tabia ya kifaa chini ya hali zisizo za kawaida. Kwa mfano, ukubwa wa mwanga kwa kawaida hupungua kadiri joto la mazingira linavyoongezeka. Voltage ya mwelekeo mzuri pia ina mgawo hasi wa joto, ikimaanisha kuwa itapungua kidogo kadiri joto linavyoongezeka. Wabunifu wanapaswa kurejelea data ya michoro, kupunguza utendaji kwa kadiri inavyofaa kulingana na mazingira yao maalum ya uendeshaji, na kuhakikisha kuendesha kwa sasa thabiti ndani ya anuwai ya joto lengwa.

5. Taarifa za Mitambo na Ufungashaji

5.1 Package Size

The 17-215 SMD LED utilizes a compact package. Key dimensions (in millimeters) are as follows, with a general tolerance of ±0.1 mm unless otherwise specified: overall package length is 2.0 mm, width is 1.25 mm, and height is 0.8 mm. The device features two anode/cathode terminals for electrical connection. A detailed dimensional drawing, including pad pitch, terminal dimensions, and lens geometry, is provided in the datasheet to guide PCB pad pattern design for optimal soldering and mechanical stability.

5.2 Polarity Identification

Correct polarity is crucial for LED operation. The package outline in the datasheet clearly indicates the anode and cathode terminals. Typically, one terminal may feature a marking or have a distinct shape (e.g., a notch or chamfer) for visual identification during manual assembly or inspection. Designers must ensure the PCB footprint pattern aligns with this polarity to prevent misplacement.

6. Welding and Assembly Guide

6.1 Reflow Soldering Temperature Profile

LED hii inaendana na mchakato wa reflow soldering wa infrared na mvuke. Kwa uchomeaji usio na risasi, lazima kufuata mkunjo maalum wa joto:

• Preheating:Heat from ambient temperature to 150-200°C within 60-120 seconds.
• Soak/Reflow:Weka kwa sekunde 60-150 kwenye joto la juu ya 217°C (joto la liquidus). Joto la kilele halipaswi kuzidi 260°C, na muda wa kuwa juu ya 255°C lazima udhibitiwe hadi sekunde 30 tu.
• Kupoa:Kiwango cha juu cha kupoa hakipaswi kuzidi digrii 6 kwa sekunde.

Inapendekezwa sana idadi ya upasuaji wa reflow isizidi mara mbili, ili kuzuia uharibifu wa mkazo wa joto kwenye kifurushi cha LED na viunganisho vya ndani vya waya.

6.2 Manual Soldering

If manual soldering cannot be avoided, extra care must be taken. The soldering iron tip temperature should be below 350°C, and the contact time with each terminal must not exceed 3 seconds. The soldering iron power should be 25W or lower. At least 2 seconds should elapse between soldering each terminal. The use of a dual-tip soldering iron for rework is recommended to minimize thermal stress, but rework after initial soldering is generally discouraged.

6.3 Storage and Moisture Sensitivity

LED imefungwa kwenye mfuko wa kinga ya unyevu ulio na kivundo cha kukausha. Usifungue mfuko kabla ya kujiandaa kutumia kipengele. Baada ya kufungua:

• LED zisizotumiwa zinapaswa kuhifadhiwa katika mazingira ya 30°C au chini, unyevunyevu wa jamaa (RH) 60% au chini.
• "Urefu wa maisha wa kiwanda" baada ya kufungua mfuko ni saa 168 (siku 7).
• Ikiwa hazijatumiwa ndani ya muda huu, LED zilizobaki lazima zipakwe tena kwenye mfuko wenye desiccant.
• Ikiwa kiashiria cha desiccant kimebadilisha rangi au wakati wa mfiduo umezidi uliowekwa, inahitaji kukaushwa kwa 60°C ±5°C kwa saa 24 kabla ya matumizi.

8. Mapendekezo ya Utumiaji

8.1 Typical Application Scenarios

Rangi ya manjano ya kijani kibichi na ukubwa mdogo hufanya LED hii ifae kwa viashiria mbalimbali vya mwanga na kazi ya mwanga wa nyuma:

• Interior ya Gari:Mwanga wa nyuma wa vifaa vya dashibodi, swichi na paneli za udhibiti.
• Vifaa vya Mawasiliano:Viashiria vya hali na taa za nyuma za kibodi katika simu, mashine za faksi na vifaa vingine vya mawasiliano.

• Uonyeshaji wa jumla:Viashiria vya hali ya umeme, uteuzi wa hali, na maonyo katika vifaa mbalimbali vya elektroniki.

8.2 Key Design Considerations

Lazima kuzuia mkondo:LED is a current-driven device. An external current-limiting resistor must always be connected in series with the LED. The resistor value is determined based on the supply voltage (V_supply) and the LED's forward voltage (V_F, inayotolewa kutoka kwenye kiwango chake) na mkondo wa mbele unaohitajika (I_F, kawaida ni 20 mA au chini) kuhesabu. Fomula ni: R = (V_supply- V_F) / I_F. Bila upinzani huu, hata ongezeko dogo la voltage ya usambazaji linaweza kusababisha ongezeko kubwa na linaloharibu la mkondo.

Usimamizi wa joto:Ingawa matumizi ya nguvu ni ya chini, kuhakikisha eneo la kutosha la shaba la PCB karibu na pedi ya LED husaidia katika upotezaji wa joto, hasa katika hali ya joto kali ya mazingira au wakati inaendeshwa kwa mkondo wa juu zaidi unaoendelea. Hii husaidia kudumisha mwanga wa pato na maisha ya huduma.

Mipaka ya matumizi:Hii LED ya kiwango cha kibiashara haijabuniwa au kuthibitishwa kwa matumizi ya uaminifu wa juu ambapo hitilafu inaweza kusababisha hatari ya usalama. Hii inajumuisha, lakini sio tu, mifumo ya kijeshi/anga, mifumo muhimu ya usalama wa magari (kwa mfano, taa za breki, viashiria viairbag), na vifaa vya matibabu vinavyoshikilia maisha. Kwa matumizi kama haya, vipengele vilivyo na sifa husika na data ya uaminifu vinapaswa kununuliwa.

9. Ulinganishi wa Teknolojia na Tofauti

Sababu kuu za kutofautisha za LED ya 17-215 ni pamoja na muundo wake wa chip maalum ya AIGaInP kuzalisha mwanga mkali wa manjano-kijani, ukubwa wake mdogo sana wa ufungaji wa 2012 (2.0x1.25mm), na kufuata viwango vya kisasa via mazingira (bila risasi, bila halojeni, RoHS, REACH). Inafanikiwa kupunguza ukubwa kwa kiasi kikubwa ikilinganishwa na LED za zamani za kupenyeza mashimo au SMD kubwa zaidi. Ikilinganishwa na LED nyingine za manjano-kijani, teknolojia ya AIGaInP kwa kawaida hutoa ufanisi mkubwa wa mwanga na utulivu bora wa rangi (kubadilika kwa joto na mkondo) kuliko vifaa mbadala vingine vya semiconductor vinavyotumiwa kwa rangi sawa. Pembe pana ya mtazamo wa digrii 130 pia ni sifa muhimu kwa matumizi yanayohitaji mwanga mpana na sawa badala ya boriti iliyolengwa.

10. Maswali Yanayoulizwa Mara kwa Mara (FAQ)

Q1: Kuna tofauti gani kati ya urefu wa wimbi la kilele (λp) na urefu wa wimbi kuu (λd)?
A1: Urefu wa wimbi la kilele ni urefu wa wimbi ambapo usambazaji wa nguvu ya wigo unafikia thamani yake ya juu kabisa. Urefu wa wimbi kuu ni urefu wa wimbi wa mwanga wa monokromati unaolingana na rangi inayohisiwa ya LED. Kwa LED zenye wigo dhaifu kiasi, hizi mbili kwa kawaida ziko karibu, lakini λd ina umuhimu zaidi katika maombi kwa ajili ya vipimo vya rangi.

Q2: Je, nikitumia chanzo cha voltage ya kudumu kilichowekwa kwa voltage ya mbele ya LED, naweza kuendesha LED hii bila kupinga kikomo cha mkondo?
A2: Hapana, haipendekezwi kufanya hivyo, na kuna uwezekano mkubwa wa kuharibu LED. Voltage ya mbele ina uvumilivu na mgawo hasi wa joto. Mabadiliko madogo ya voltage ya usambazaji au ongezeko la joto la LED yanaweza kusababisha ongezeko kubwa na lisilodhibitiwa la mkondo, na kusababisha joto kupita kiasi na kushindwa kufanya kazi. Hakikisha unatumia upinzani wa mfululizo au kiendesha kikomo cha mkondo maalum.

Q3: Kwa nini kuna kikomo cha "maisha ya karakana" kali baada ya kufungua mfuko wa kuzuia unyevu?
A3: SMD components absorb moisture from the atmosphere. During high-temperature reflow soldering, this trapped moisture can rapidly vaporize, creating internal pressure that may lead to package cracking (the "popcorn" effect) or delamination, resulting in failure. Floor life and baking procedures are used to manage this Moisture Sensitivity Level (MSL).

Q4: How to interpret the binning codes (CAT, HUE, REF) when ordering?
A4: You can specify the exact binning codes you require based on your application's needs for brightness (CAT), color (HUE), and forward voltage (REF). Ordering tighter bins ensures higher consistency in the final product's appearance and electrical performance. If not specified, you will receive components from the standard production bins.

11. Mifano ya Uundaji na Matumizi Halisi

Mfano 1: Taa ya Nyuma ya Swichi ya Dashibodi
Katika dashibodi ya gari, LED nyingi za 17-215 zinaweza kuwekwa nyuma ya kofia ya swichi wazi. Pini ya GPIO ya microcontroller inaweza kuwashwa kutoka kwa mfumo wa 12V wa gari kupitia transistor. Kokotoa upinzani wa mfululizo kwa kila LED. Kwa mfano, kwa kutumia usambazaji wa umeme wa 12V, V_Fni 2.1V (Kiwango 1), lengo I_FFor 20mA: R = (12V - 2.1V) / 0.02A = 495 ohms. A standard 510 ohm resistor will be suitable, resulting in I_F≈ 19.4 mA. The wide viewing angle ensures the switch is evenly illuminated.

Example 2: Network Equipment Status Indicator
For the "Link Activity" indicator on a router, a single LED can be driven directly by a 3.3V logic signal. Using V_F= 1.9V (gear 0) and I_F= 15 mA to reduce power consumption and extend lifespan: R = (3.3V - 1.9V) / 0.015A ≈ 93.3 ohms. A 100-ohm resistor will be used. The bright yellow-green color is very eye-catching and is often associated with network activity.

12. Introduction to Working Principles

A light-emitting diode (LED) is a semiconductor device that emits light through a process called electroluminescence. The 17-215 LED uses an AIGaInP (aluminum gallium indium phosphide) compound semiconductor. When a forward voltage is applied across the p-n junction, electrons from the n-type region and holes from the p-type region are injected into the active region. When these charge carriers (electrons and holes) recombine, they release energy. In AIGaInP material, this energy is released primarily as photons (light particles) with a wavelength corresponding to the bandgap energy of the semiconductor material. The specific composition of Al, Ga, In, and P atoms is engineered to create a bandgap that produces yellow-green light with a peak wavelength of approximately 575 nm. An epoxy resin lens encapsulates the chip, protecting it and shaping the light output to achieve the desired 130-degree viewing angle.
