5. Uchambuzi wa Mkunjo wa Utendaji

Mwongozo unarejelea mikunjo ya kawaida ya utendaji ili kuelezea uhusiano kati ya vigezo muhimu. Ingawa michoro maalum haijarudiwa katika maandishi, kwa kawaida hujumuisha:

• I-V (Current-Voltage) Curve:Inaonyesha uhusiano kati ya voltage ya mbele (VF) na mkondo wa mbele (IF) kwa LED ya kijani na ya manjano. Hii ni muhimu sana katika kubuni saketi za kudhibiti mkondo.
• Uzito wa Mwanga dhidi ya Mkondo wa Mbele:Elezea jinsi pato la mwanga linavyobadilika kulingana na mkondo wa kuendesha, ukisisitiza uhusiano usio wa mstari, unaosaidia kuboresha hali ya kuendesha ili kufikia mwangaza unaohitajika.
• Uwiano wa nguvu ya mwanga dhidi ya joto la mazingira:Elezea jinsi pato la mwanga linavyopungua kadiri joto la kiungo linavyoongezeka, jambo muhimu kwa usimamizi wa joto katika matumizi ya joto la juu au mkondo mkubwa.
• Usambazaji wa wigo:Shows the relationship between relative radiant power and wavelength, confirming the peak wavelength (λP) and spectral width (Δλ) for each color.

These curves are crucial for designers to predict actual performance beyond the single-point data in the table.

6. Mwongozo wa Uchomaji na Usanikishaji

6.1 Uhifadhi na Uendeshaji

• Uhifadhi:LEDs should be stored in an environment with a temperature not exceeding 30°C and relative humidity not exceeding 70%. If removed from the original sealed packaging, they should be used within three months. For long-term storage outside the original packaging, please use a sealed container with desiccant or a nitrogen environment.
• Cleaning:If necessary, clean using alcohol-based solvents such as isopropyl alcohol.

6.2 Pin Forming and PCB Mounting

• Bend the leads at a minimum distance of 3mm from the LED lens base. Do not use the lead frame base as a fulcrum.
• Pin forming must be performed at room temperature, and在 soldering.
• Katika mchakato wa kuingiza PCB, tumia nguvu ya kushinikiza inayohitajika na ndogo zaidi, ili kuepuka kutumia mkazo wa mitambo mwingi kwa vipengele.

6.3 Soldering Process

Lazima uwe na pengo la angalau 2mm kati ya msingi wa lenzi/kofia na sehemu iliyochomelewa. Epuka kuzamisha lenzi/kofia kwenye chumvi ya kuchomelea.

Masharti yanayopendekezwa ya kuunganishia:

Warning:Excessively high soldering temperature or duration may cause lens deformation or catastrophic LED failure. Do not apply stress to the leads while the LED is heated from soldering.

7. Ubunifu wa Sakiti ya Kusukuma

LED is a current-driven device. Its forward voltage (VF) has tolerances and varies with temperature. To ensure uniform brightness when driving multiple LEDs (especially in parallel), it ishighly recommended.

• Mradi unaopendekezwa (A):Kila LED ina upinzani wake wa mfululizo unaounganishwa na chanzo cha umeme. Hii inaweza kulipa tofauti za VF za kila LED, kuhakikisha kila LED inapata mkondo sawa, na hivyo kufikia mwangaza sawa.
• Mradi usiopendekezwa (B):Kuunganisha LED nyingi moja kwa moja kwa sambamba, ukishiriki upinzani mmoja. Tofauti katika sifa za I-V za kila LED zitasababisha usambazaji usio sawa wa mkondo, kusababisha tofauti kubwa katika mwangaza, na kunawezekana kusababisha LED moja kubeba mkasi mkubwa kupita kiasi.

Thamani ya upinzani wa mfululizo (R) inahesabiwa kwa kutumia sheria ya Ohm: R = (Voltage ya usambazaji - Voltage ya mbele ya LED) / Mkondo unaotarajiwa, ambapo mkondo unaotarajiwa haupaswi kuzidi 20mA kama mkondo wa juu wa moja kwa moja wa mbele.

8. Maelezo ya Matumizi na Tahadhari

8.1 Matumizi Yanayofaa

This LED lamp is suitable for general indicator purposes in indoor and outdoor signage, as well as in standard electronic equipment within the listed fields of communication, computer, consumer, and industrial applications.

8.2 Design Considerations

• Thermal Management:Although the power consumption is low, it is necessary to ensure that the operating ambient temperature does not exceed 85°C. In enclosed spaces or under high ambient temperatures, derating of luminous intensity must be considered.
• Current Control:Daima tumia njia ya kuendesha ya umeme wa mara kwa mara au chanzo cha voltage chenye upinzani wa mfululizo. Kamwe usiunganishe moja kwa moja kwenye chanzo cha voltage kisicho na hatua za kudhibiti kikomo.
• Kuzuia ESD:Ingawa haijasemwa wazi, utaratibu wa kawaida wa usindikaji wa ESD unapaswa kufuatwa wakati wa usanikishaji ili kuzuia uharibifu wa chipu ya semiconductor.
• Optical Design:The 100-degree viewing angle and diffuser lens provide a wide, soft illumination pattern, suitable for panel indicator lights. For focused or narrow beam applications, a different type of lens is required.

9. Technical Comparison and Positioning

Bidhaa hii inawakilisha suluhisho la kawaida la kiashiria cha kuingiza moja kwa moja. Sifa zake kuu za utofautishaji ni pamoja na:

• Ganda lililojumuishwa:Ikilinganishwa na kutumia LED tofauti na viunga pekee, kiunga cha pembe mraa nyeusi kilichokusanywa mapema kinaurahisi muundo na usanikishaji wa bodi ya mzunguko, huku ukiboresha tofauti ya mwonekano.
• Single Package Dual Color:Combining green and yellow indicator lights in a compact through-hole package saves PCB space compared to using two separate single-color LEDs.
• Material Compliance:Kama kipengele kisicho na risasi na kinachokidhi viwango vya RoHS, kinakidhi mahitaji ya kanuni za mazingira katika utengenezaji wa kisasa wa elektroniki.
• Inafaa kwa otomatiki:Ufungaji wa mkanda na diski unaunga mkono michakato ya usanikishaji ya kiwango kikubwa na ya otomatiki, na kupunguza gharama za wafanyikazi.

Ikilinganishwa na vifaa vya LED vya SMD, toleo hili la kuingizwa moja kwa moja lina faida katika utengenezaji wa mfano, usanikishaji wa mikono, na matumizi yanayohitaji nguvu zaidi ya muunganisho wa mitambo au mwanga kupenya bodi. Hata hivyo, LED za SMD kwa kawaida huruhusu msongamano mkubwa wa kufunga, na zinafaa zaidi kwa mstari wa usanikishaji wa otomatiki kamili na wa kasi wa kuchukua-na-kuweka.

10. Frequently Asked Questions (FAQ)

Q1: Can I operate this LED continuously at the 60mA peak current?
A1: Hapana. Kikomo cha kilele cha mkondo wa mbele (60mA) kinatumika tu kwa hali ya chini ya uwiano wa kazi (≤10%), na mipigo mifupi sana (≤0.1ms). Kikomo cha juu cha mkondo wa mbele wa DC unaoendelea ni 20mA. Kuzidi thamani hii kunaweza kusababisha joto kupita kiasi, kukua kwa umri haraka au kushindwa kufanya kazi.

Q2: Kwa nini kiwango cha kawaida cha nguvu ya mwanga cha LED ya kijani (420mcd) na LED ya manjano (11mcd) kinatofautiana sana kwa mkondo sawa wa 10mA?
A2: Hii inatokana hasa na vifaa tofauti vya semikondukta (InGaN kwa kijani, AlInGaP kwa manjano) na uwezo wa macho ya binadamu kuona mwanga wakati wa mchana (mkondo wa CIE), ambao unafikia kilele katika eneo la kijani (karibu 555nm). Macho ya binadamu yana uwezo mdogo wa kuhisi urefu wa wimbi la mwanga wa manjano, kwa hivyo nguvu ya mwanga (inayopimwa kwa mcd) inayopimwa kwa nguvu sawa ya mnururisho ni ya chini.

Q3: Nini kitatokea ikiwa LED haitawekwa kwa umbali wa 2mm kutoka kwa msingi wa lenzi wakati wa kuunganishwa kwa kutumia chuma cha kuuzimisha?
A3: Kutumia joto karibu sana na lens au kifuniko cha plastiki kunaweza kusababisha kuyeyuka, kubadilika umbo, au kubadilika rangi. Joto pia linaweza kupitishwa kupitia pini hadi kwenye chip ya LED kupita kiasi, ikivawezekana kuharibu kiungo cha semiconductor au waya za ndani za kuunganisha.

Q4: Je, msimbo wa kugawanya (binning code) unafasiriwaje wakati wa kuagiza?
A4：Bin code（例如，绿色LED的KL & G10）定义了您将收到的LED的发光强度和主波长的保证范围。指定分档允许您为应用选择性能一致的LED。如果颜色或亮度均匀性至关重要，您应指定严格的分档，并可能要求提供测试数据。

Q5: Je, mzunguko wangu unahitaji diode ya ulinzi ya kinyume?
A5: Mwongozo wa spec unasema kifaa hiki hakikusudiwa kufanya kazi kwa kinyume, na unabainisha mkondo wa kinyume (IR) chini ya majaribio ya 5V. Ingawa voltage ndogo ya kinyume mara kwa mara huenda isisababisha hitilafu mara moja, haipendekezwi. Katika mizunguko ambapo voltage ya kinyume inaweza kutokea (k.m., kuunganishwa kwa AC, mzigo wa inductive), ulinzi wa nje unapendekezwa, kama kuunganisha diode mfululizo na LED au kuweka diode iliyoelekezwa kinyume sambamba na LED, ili kuzuia voltage ya kinyume kutumika kwa LED.
