XL-304UBC直插发光二极管产品概述

XL-304UBC是成兴光(Xinglight)推出的一款3mm圆形直插LED,主打“白发蓝”高辨识度视觉效果与聚光型设计,适配传统插件工艺,广泛应用于电子设备状态指示、小型显示等场景,是工业控制、消费电子领域的经典入门级选型。

一、产品基本定位与核心特性

作为低成本高可靠性的指示类LED,XL-304UBC的核心定位是低功耗、易驱动的状态指示与辅助照明器件,核心特性包括:

  • 3mm标准圆形灯头,兼容所有传统PCB插件线;
  • 无色透明透镜+白发蓝外观,蓝光纯度高、视觉辨识度强;
  • 长脚设计(比常规插件脚长20%),方便手工焊接或波峰焊作业;
  • 额定20mA电流下功率仅70mW,无需额外散热,适合长期通电场景。

二、核心性能参数详解

(1)光学参数:高亮度聚光蓝光

  • 波长范围:460nm~470nm,峰值465nm—— 属于人眼感知清晰且不易疲劳的蓝光波段,无偏紫/偏青问题;
  • 发光强度:5000mcd—— 比普通3mm蓝灯亮度提升30%,强光环境下仍清晰可见;
  • 发光角度:30°—— 聚光型设计,光线集中性好,适合定向指示(如设备面板状态灯)。

(2)电学参数:低功耗易匹配

  • 正向压降(Vf):3.4V—— 蓝光LED常规压降,与5V/12V电源兼容(需限流电阻即可稳定工作);
  • 额定正向电流(If):20mA—— 常规驱动电流,短时间可承受25mA以内过载;
  • 额定功率:70mW—— 连续工作100小时仅耗电0.07Wh,长期通电无能耗压力。

(3)结构参数:标准化插件封装

  • 灯头尺寸:D=3mm圆形,符合行业标准,可直接替换同类产品;
  • 透镜类型:无色透明环氧树脂—— 透光率≥90%,寿命期内无黄化,蓝光透过率稳定;
  • 引脚材质:铜质长脚—— 抗氧化、焊接牢固,手工烙铁/波峰焊适配性好。

三、典型应用场景

XL-304UBC的特性决定了它覆盖以下高频场景:

  1. 电子设备状态指示:路由器电源灯、交换机连接灯、万用表功能指示灯;
  2. 小型显示模组:数码管辅助背光、字符显示板段码灯(需搭配驱动电路);
  3. 消费电子与玩具:发光钥匙扣、模型车尾灯、儿童电子玩具装饰灯;
  4. 工业控制:PLC模块I/O指示灯、传感器状态反馈灯;
  5. 户外小型装置:太阳能庭院灯辅助指示、自行车尾灯聚光元件(需防水封装)。

四、可靠性与环境适应性

  • 工作温度:-20℃~+85℃—— 适应北方冬季室内、南方夏季户外等场景;
  • 储存条件:-30℃~+60℃,湿度≤85%—— 常规仓库即可储存,无需特殊温湿度控制;
  • 寿命:额定电流下≥50000小时—— 远高于白炽灯,适合长期通电指示需求。

五、使用注意事项

为确保稳定工作,需注意:

  1. 限流电阻匹配:5V电源下,R=(5-3.4)/0.02=80Ω(推荐100Ω/0.125W电阻,避免过流);
  2. 焊接要求:烙铁头温度≤300℃,焊接时间≤3秒,避免透镜变形;
  3. 静电防护:操作时佩戴防静电手环,使用防静电烙铁(LED对静电敏感);
  4. 反向电压限制:短时间反向电压≤5V,长期反向会导致芯片漏电。

XL-304UBC凭借标准化封装、稳定性能与亲民价格,成为3mm直插蓝灯领域的经典选型,可满足大多数入门级LED指示与辅助照明需求。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
