XL-1808UBC(1808封装)蓝色LED产品概述

一、产品基本信息

XL-1808UBC是国内LED厂商成兴光(Xinglight) 推出的1808封装蓝色发光二极管,属于常规指示/辅助照明类基础元件。1808为英制贴片尺寸(约4.5mm×2.0mm),体积小巧、贴装便捷,适配小型电子设备的高密度布局需求,是家电、仪器仪表、玩具等领域的常用选择。

二、核心性能参数详解

1. 光学特性

  • 颜色与波长:发光为标准蓝色,波长范围460nm~475nm,峰值波长465nm——此区间是蓝光LED的典型发光范围,视觉辨识度高,且无紫外波段,适合长期观察的指示场景。
  • 亮度与视角:发光强度500mcd,满足日常指示的亮度需求(如家电开关、仪器状态提示);120°宽视角设计,无需额外透镜即可覆盖广域视野,适配多人观察场景。

2. 电学特性

  • 正向压降(Vf):典型值3.2V,与5V、3.3V主流电源兼容性好,仅需串联限流电阻即可稳定驱动。
  • 功率与电流:额定功率75mW,额定正向电流20mA——低功耗特性适合电池供电设备(如遥控器、玩具),可延长续航。

3. 封装与尺寸

1808贴片封装(约4.5mm×2.0mm×1.5mm),支持SMT自动化生产,贴装效率高;环氧树脂封装防潮防尘,抗振动性能优于直插LED,适合移动电子设备。

三、应用场景适配

XL-1808UBC的性能特点使其覆盖多类场景:

1. 小型指示类

  • 家电:电视、空调的电源/功能指示灯;
  • 仪器仪表:万用表、传感器的信号/工作状态提示;
  • 开关插座:智能开关、USB插座的充电/电源指示。

2. 背光辅助

  • 小型设备:遥控器、计算器的局部背光(搭配导光板可均匀发光);
  • 穿戴设备:智能手环的辅助指示背光(低功耗不影响续航)。

3. 简易照明与模型

  • 玩具模型:儿童玩具车、模型飞机的装饰灯/状态灯;
  • 应急照明:户外露营灯的辅助指示、小型应急灯的低亮度模块。

四、可靠性与环境适应性

1. 宽温工作范围

-40℃~+85℃的工作温度,可适应北方户外、厨房家电、汽车内部等复杂温差场景,无需额外温控设计。

2. 长寿命特性

基于成兴光芯片工艺,寿命可达5万小时以上,亮度衰减缓慢,长期使用无需频繁更换,降低维护成本。

3. 封装可靠性

环氧树脂封装防潮防尘,芯片与引脚连接牢固,抗振动性能优异,可承受电子设备运输/使用中的轻微冲击。

五、选型与使用注意事项

1. 电流电压控制

  • 额定电流20mA,实际使用不超过22mA(避免过热);
  • 5V电源需串联90Ω~100Ω限流电阻(公式:R=(V电源-Vf)/If),建议用1/8W金属膜电阻。

2. 焊接与静电防护

  • 焊接温度:回流焊≤260℃(10秒内),手工焊≤350℃(3秒内),避免损伤芯片;
  • 静电防护:生产/安装需戴防静电手环,工作台接地,防止静电击穿。

3. 存储维护

  • 未开封存储:25℃±5℃、湿度<60%干燥环境;
  • 开封后1个月内使用,避免引脚氧化影响焊接。

六、总结

XL-1808UBC是一款性能稳定、性价比高的1808封装蓝色LED,兼顾亮度、兼容性与环境适应性,广泛适用于小型指示、背光辅助及简易照明场景。其小巧封装、宽温范围与长寿命特性,使其成为电子设计中常用的基础元件,可满足多数小型设备的显示需求。

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
