Sehemu hii inatoa uchambuzi wa kina na wa kielelezo wa vigezo muhimu vya utendaji wa kifaa kulingana na hati ya maelezo. Isipokuwa imebainishwa vinginevyo, vipimo vyote vimefafanuliwa kwa joto la mazingira (Ta) la 25°C.

2.1 Viwango vya Juu Kabisa

Viwango hivi vinafafanua mipaka ya mkazo ambayo inaweza kusababisha uharibifu wa kudumu wa kifaa. Katika usanifu unaoaminika, haipaswi kuhakikishiwa au kuzidi kufanya kazi kwenye au kuzidi mipaka hii, na inapaswa kuepukwa.

Matumizi ya Nguvu (Po):

• 160 mW. This is the maximum power that the package can dissipate as heat.DC Forward Current (If):
• 40 mA. The maximum continuous forward current that can be applied.Reverse Voltage (Vr):
• 5 V. Exceeding this voltage under reverse bias may cause immediate breakdown.Operating Temperature Range (Topr):
• -40°C to +85°C. The ambient temperature range for normal operation.Upeo wa joto la uhifadhi (Tstg):
• -40°C hadi +100°C.Joto la kiungo (Tj):
• 90°C. Joto la juu kabisa linaloruhusiwa kwa kiungo cha semiconductor chenyewe.2.2 Tabia za optoelektroniki

These are typical performance parameters under specified test conditions.

Mwingilio wa mnururisho (Φe):

• Katika mkondo wa mbele (If) wa 20mA, ni 14-26 mW (kiwango cha chini-kawaida-kiwango cha juu). Hii ni pato la jumla la nguvu ya mwanga katika wigo wa mionzi ya ultraviolet. Kipimo cha uvumilivu ni ±10%.Pembe ya mtazamo (2θ1/2):
• Digrii 135 (kiwango cha kawaida). Hii inafafanua anuwai ya pembe ambayo ukali wa mwanga wa ultraviolet unaotolewa hupungua hadi nusu ya kilele.Urefu wa wimbi la kilele (λp):
• Wakati If=20mA, ni 362.5-370 nm. Urefu maalum wa wimbi ambapo LED hutoa nguvu ya juu zaidi ya mwanga, na urefu wa wimbi wa katikati ni takriban 365nm. Toleransi ni ±3nm.Voltage ya mbele (Vf):
• Wakati If=20mA, ni 2.8-4.0 V. Mshuko wa voltage kwenye LED wakati sasa maalum inapitishwa. Toleransi ya kipimo ni ±0.1V.Sasa ya nyuma (Ir):
• Wakati voltage ya nyuma (Vr) ni 1.2V, ni hadi 10 µA kiwango cha juu. Kigezo hiki kinajaribiwa ili kuthibitisha sifa zake zinazofanana na diode ya Zener, lakini kifaa hikiis not designed for reverse operation.Prolonged reverse bias may lead to failure.Thermal Resistance (Rθj-s):
• 53 °C/W (typical). This key parameter indicates the efficiency of heat transfer from the semiconductor junction (j) to the solder point or case (s). A lower value means better heat dissipation.2.3 Thermal Management Considerations

The thermal resistance of 53°C/W is a critical design factor. For example, at the maximum rated power dissipation of 160mW, the temperature rise from solder point to junction is approximately 160mW * 53°C/W = 8.5°C. Designers must ensure that the PCB and system design maintain the solder point temperature at a sufficiently low level so that the junction temperature (Tj) does not exceed its maximum of 90°C, especially when operating at high current or high ambient temperature. Exceeding Tj shortens lifetime and reduces radiant output.

3. Explanation of the Binning Code System

Based on key parameters, devices are classified into different performance bins to ensure consistency within the same production lot. The binning code is marked on the packaging.

3.1 Uwekaji wa kiwango cha Voltage ya Mbele (Vf)

When measured at If=20mA, devices are sorted into three voltage bins (V1, V2, V3). This allows designers to select LEDs with similar voltage drops for applications where current matching in parallel strings is critical, or to predict power supply requirements more accurately.

3.2 Uwekaji wa kiwango cha Flux ya Mionzi (Φe)

The optical output power is sorted into six categories (R3 through R8), each representing a 2mW range from 14mW to 26mW (at If=20mA). This enables selection based on the required UV intensity, facilitating brightness matching in multi-LED arrays.

3.3 Uwekaji wa kiwango cha Urefu wa Wimbi la Kilele (λp)

The center emission wavelength is sorted into three tight ranges (P3M2, P3N1, P3N2), each spanning 2.5nm around the 365nm target wavelength. This is crucial for applications sensitive to specific UV wavelengths, such as initiating particular photoinitiators in curing processes.

4. Performance Curve Analysis

The datasheet provides several characteristic curves, which are essential for understanding the device's behavior under real-world conditions.

4.1 Relative Radiant Flux vs. Forward Current

This curve shows that the optical output (radiant flux) increases superlinearly with forward current. While driving at higher currents yields more UV output, it also increases power consumption and junction temperature, leading to reduced efficiency and accelerated aging. The typical test condition of 20mA represents a balanced operating point.

4.2 Forward Current vs. Forward Voltage (I-V Curve)

Curve ya I-V inaonyesha uhusiano wa kielelezo wa kawaida wa diode. Voltage ya "kigeugeu" ni takriban 3V. Curve hii ni muhimu sana kwa kubuni saketi za kudhibiti mkondo, iwe kwa kutumia upinzani rahisi au madereva ya mkondo wa kudumu.

4.3 Mzunguko wa Mionzi wa Jamaa dhidi ya Joto la Kiungo

Mchoro huu unaonyesha mgawo hasi wa joto wa pato la LED. Kadiri joto la kiungo (Tj) linavyopanda, flux ya mionzi hupungua. Hii inasisitiza umuhimu mkubwa wa usimamizi bora wa joto katika matumizi ili kudumisha pato la ultraviolet thabiti kwa muda na chini ya hali tofauti za uendeshaji.

4.4 Wigo wa Utoaji wa Jamaa

Mchoro wa wigo unaonyesha usambazaji nyembamba wa Gauss unaozingatia kwenye urefu wa wimbi la kilele (mfano ~365nm). Upana wa Nusu ya Urefu Kamili (FWHM) ni sifa ya kawaida ya LED ya ultraviolet, ikionyesha kuwa inatoa mwanga wa UV-A safi kiasi, bila uvujaji dhahiri wa mwanga unaoonekana au infrared.

5. Taarifa za Mitambo na Ufungaji

5.1 Vipimo vya Umbo

Kifaa hiki kinatumia ufungaji wa juu usio na uso uliowekwa. Vipimo muhimu (milimita) ni takriban: urefu 3.5mm, upana 3.2mm, urefu 1.9mm. Kathodi kawaida hutambuliwa kupitia alama kwenye ufungaji. Mchoro wa kina wa vipimo umetolewa kwenye faili ya chanzo, na uvumilivu wa kawaida ni ±0.1mm.

5.2 Mpangilio Unaopendekezwa wa Pads za PCB

Muundo wa pedi ya chuma umetolewa kwa ajili ya kuunganisha kwa njia ya infrared au mvuke. Muundo huu umeboreshwa ili kuhakikisha umbo sahihi la mshono, utulivu wa mitambo, na uhamishaji bora wa joto kutoka kwa pedi ya kupokanzwa ya LED (ikiwepo) au pini hadi safu ya shaba ya PCB. Kufuata mapendekezo haya ni muhimu kwa ajili ya kuegemea.

• Si zaidi ya 300°C.Muda wa kuchomelea:
• Kila mchomo usizidi sekunde 3.Vizuizi:
• Uchomeleaji ufanyike mara moja tu. Urejeshaji wa kazi haupendekezwi kabisa.6.3 Usafishaji

Unspecified chemical cleaners may damage the LED package. If cleaning after soldering is required, the only recommended method is to immerse the LED in ethanol or isopropyl alcohol at room temperature for no more than one minute.

6.4 Tahadhari za Kuzuia Utoaji Umeme wa Tuli (ESD)

UV LEDs are sensitive to electrostatic discharge (ESD) and voltage surges. Appropriate ESD control measures must be taken during handling and assembly:

Tumia kifungo cha mkono au glavu za kuzuia umeme tuli.

8. Application Design Considerations

8.1 Driving Method

LED is a current-driven device. For reliable and consistent operation, it

kuendeshwana chanzo cha mkondo wa mara kwa mara, sio chanzo cha voltage ya mara kwa mara. Kutumia chanzo cha voltage kunaweza kusababisha udhibiti wa joto uliopotea na uharibifu. Wakati wa kuunganisha LED nyingi, muunganisho wa mfululizo unapendekezwa kwa sababu huhakikisha mkondo sawa kupitia kila kifaa. Ikiwa muunganisho wa sambamba hauepukiki, inashauriwa sana kutumia upinzani wa kikomo wa mkondo tofauti au kiendeshi tofauti kwa kila tawi, ili kulipa fidia tofauti za asili za voltage ya mbele (Vf) na kuhakikisha usawa wa nguvu.8.2 Upunguzaji wa Joto na Ubunifu wa PCB

Kwa kuzingatia upinzani wa joto wa 53°C/W (Rθj-s), PCB hutumika kama kifaa kikuu cha kupoza joto. Tumia PCB yenye unene wa kutosha wa shaba (mfano, oz 2). Buni pedi ya shaba chini ya LED na kuzunguka kwa ukubwa mkubwa iwezekanavyo. Kuunganisha pedi kwa safu ya ardhini ya ndani au visima vya kupitisha joto kwa safu ya shaba ya chini kunaboresha sana usambazaji wa joto. Katika matumizi ya nguvu kubwa au hali ya joto ya mazingira ya juu, fikiria hatua za ziada za usimamizi wa joto, kama vile PCB yenye msingi wa chuma (MCPCB) au kupoza kwa kutumia nguvu.

8.3 Ubunifu wa Optics

Pembe ya maono ya digrii 135 hutoa muundo mpana wa utoaji. Kwa matumizi yanayohitaji kuzingatia au kusawazisha mwanga wa ultraviolet, ni lazima kutumia vifaa vya pili vya macho, kama vile lenzi au kioo cha kutafakari. Nyenzo za vifaa hivi vya macho lazima ziwe wazi kwa mwanga wa UV-A (mfano, kioo maalum, quartz, au plastiki wazi kwa UV kama acrylic). Nyenzo za kawaida za macho zinaweza kufyonza mionzi ya ultraviolet.

8.4 Usalama na Udhibitisho wa Kutokuwa na Hatia

Kifaa hiki kimeundwa kutumika katika vifaa vya kawaida vya elektroniki. Hakijaundwa au kuthibitishwa kwa matumizi ambapo kushindwa kunaweza kuhatarisha moja kwa moja uhai, afya, au usalama—mfano, anga, usafiri, mifumo ya kusaidia uhai ya matibabu, au udhibiti wa nyuklia. Kwa matumizi kama hayo, ni lazima kushauriana na mtengenezaji wa vipengele, na kunaweza kutumika vipengele vilivyothibitishwa kwa matumizi ya uaminifu wa juu (hi-rel) au matibabu.

9. Ulinganishi wa Kiufundi na Mazingira ya Soko

9.1 Faida Ikilinganishwa na Vyanzo vya Kawaida vya Mwanga wa Ultraviolet

Ikilinganishwa na vyanzo vya jadi vya mwanga wa ultraviolet kama vile taa za mvuke wa zebaki, LED hii inatoa:

Kuwasha/Kuzima Papo hapo:

• Hakuna haja ya muda wa joto au baridi.Maisha marefu:
• Maelfu ya saa, wakati bomba la taa ni maelfu tu ya saa.Ufanisi wa juu wa nishati:
• Ufanisi wa juu wa mnururisho, hubadilisha zaidi ya umeme kuwa mwanga muhimu wa ultraviolet.Ukubwa mdogo na kubadilika kwa muundo:
• Inaweza kuunganishwa katika vifaa vidogo vya kubebebea.Uendeshaji wa joto la chini:

• Hauna zebaki.Upekee wa urefu wa wimbi:
• Hutoa mwanga wa bendi nyembamba, kupunguza athari za zisizohitajika au joto.9.2 Kubadilishana na Kuzingatia katika Ubunifu

Ingawa yenye nguvu kwa ukubwa wake, pato la jumla la ultraviolet la LED moja ni chini ya la taa za jadi. Kufikia mnururisho sawa wa jumla kwa kawaida huhitaji safu ya LED, jambo linaloweka changamoto za muundo katika usimamizi wa joto, kuendesha mkondo, na usawa wa optiki. Gharama ya awali ya kipengee kwa kila kitengo cha nguvu ya mwanga inaweza kuwa kubwa zaidi, lakini hii kwa kawaida husawazishwa na akiba katika nishati, matengenezo, na maisha ya mfumo.

10. Maswali Yanayoulizwa Mara kwa Mara (FAQ)

10.1 Mkondo unaopendekezwa wa uendeshaji ni upi?

Mwongozo wa maelezo ya kiufundi unaelezea kifaa hiki kwenye 20mA, ambayo ni sehemu ya kawaida na ya kuaminika ya uendeshaji. Inaweza kuendeshwa hadi thamani yake kamili ya juu zaidi ya 40mA, lakini hii itaongeza halijoto ya kiungo, inayoweza kufupisha maisha na kupunguza ufanisi (lumen kwa kila watt). Uchambuzi wa kina wa muundo wa joto unahitajika kabla ya kufanya kazi kwa zaidi ya 20mA.

10.2 Can I drive this LED directly with a 3.3V or 5V logic supply?

It cannot be driven directly. The forward voltage range is 2.8V to 4.0V. A simple series resistor with a 5V supply can be used to limit the current. For a 3.3V supply, if the LED's Vf is on the higher end (e.g., 3.6V-4.0V), there may be insufficient voltage headroom, necessitating a boost converter or a dedicated LED driver IC. For optimal performance and longevity, a constant current circuit should always be used.

10.3 How do I interpret the binning code on the bag?

The binning code is a combination of letters and numbers (e.g., V2R5P3N1), indicating the performance groups for forward voltage (V), radiant flux (R), and peak wavelength (P). Please refer to the binning code table in Section 3 to understand the specific range for each parameter for your lot of components.

10.4 Je, inahitaji ulinzi wa macho?

UV-A radiation (315-400nm) does not cause immediate harm like UV-B or UV-C, but prolonged or high-intensity exposure can cause damage to the eyes (photokeratitis) and skin (premature aging, increased cancer risk). Always use appropriate Personal Protective Equipment (PPE), such as UV-blocking safety glasses or face shields, when handling or testing these LEDs.

12.1 Working Principle

The working principle of a UV LED is the same as that of a visible light LED: electroluminescence in a semiconductor p-n junction. When a forward voltage is applied, electrons and holes recombine in the active region (typically made of aluminum gallium nitride - AlGaN for this wavelength). The energy released during recombination is emitted in the form of photons. The specific wavelength (color) of the light is determined by the bandgap energy of the semiconductor material. A bandgap corresponding to approximately 3.4 eV produces photons of about 365nm (UV-A).

12.2 Mielekeo ya Sekta

The UV LED market is driven by several key trends:

Nguvu ya pato na ufanisi vinazoendelea kuboreshwa:

• Utafiti mwingi na maendeleo umelenga kutengeneza UV-B na UV-C LED zenye ufanisi (hadi 250nm), zinazotumika kwa usafi, usafishaji wa maji na matibabu ya kiafya, zikipingana na taa za zebaki katika soko jipya.Kupunguza gharama:
• Uchumi wa kiwango na uboreshaji wa mchakato wa utengenezaji unapunguza taratibu gharama kwa kila milliwati ya mwanga wa UV, na kuharakisha utumizi katika viwanda mbalimbali.Ujumuishaji wa mfumo:
• Mwelekeo ni pamoja na kuunganisha viendeshi, vihisi na chipi nyingi za LED kwenye vifurushi vya kiotomatiki na vya moduli vya toa mionzi ya UV, ili kurahisisha muundo na utekelezaji wa matumizi yanayodhibitiwa zaidi.Trends include integrating drivers, sensors, and multiple LED chips into smart, modular UV emitter packages for easier design-in and more controlled application.
