EVERLIGHT 15-21/BHC-AP1Q2/3T (1206) 蓝色贴片发光二极管——产品概述

一、产品简介

15-21/BHC-AP1Q2/3T 为 EVERLIGHT(台湾亿光)出品的一款 1206 尺寸蓝色贴片发光二极管(SMD LED)。该器件采用独立二极管配置与无色透明透镜设计,提供均匀的蓝色发光(峰值 468 nm),适用于状态指示、面板背光、通用指示灯及消费类电子小信号照明场合。

主要参数(典型值):

  • 发光颜色:蓝色
  • 峰值波长:468 nm(光谱范围 464.5–476.5 nm)
  • 正向电压 Vf:≈ 3.3 V(在 20 mA)
  • 额定正向电流 If:20 mA
  • 功率限制:75 mW(器件最大功耗)
  • 发光强度:45–112 mcd(在标准测试条件下)
  • 发光角度:130°(全角,FWHM)
  • 封装:1206 SMD
  • 二极管配置:独立二极管(单颗发光芯片)
  • 透镜颜色:无色透明
  • 工作温度:-40 ℃ 至 +85 ℃

二、光电特性说明

  • 峰值波长 468 nm 表明光色处于纯净蓝色区域,适合对色彩要求较高的指示用途或与其他颜色混光时作为蓝通道。
  • 发光强度 45–112 mcd 为典型光强范围,实际值受制造批次与测试条件影响;标明值通常在 If=20 mA、标准测试视角下测得。
  • 发光角度 130°(全宽)表示光束较宽,适合广角指示与面板均匀照明,不适合需要聚光或远距离可视的场合。

三、电气与热特性与设计注意

  • 正向电压 Vf ≈3.3 V(20 mA),在设计驱动电路时应以此为基准并考虑容差与温度漂移。
  • 功率消耗:在 20 mA 条件下实际耗散功率约为 P = Vf × If = 3.3 V × 0.02 A = 66 mW,小于器件最大额定 75 mW,但长时间工作或多颗并列时仍需注意散热与退化。
  • 驱动建议:采用限流电阻或恒流驱动。示例电阻计算(以 5 V 供电为例):R = (Vcc − Vf) / If = (5 − 3.3) / 0.02 ≈ 85 Ω,常用 82 Ω 或 100 Ω。若使用 12 V:R ≈ 435 Ω,常用 430 Ω 或 470 Ω。电阻功率需按 (Vdrop)^2 / R 或 Vdrop × If 计算并留有裕量。
  • 温度影响:高环境温度或密集贴片会增加结温,从而降低光输出并影响寿命。保持良好 PCB 散热(铜箔面积、散热层)有利于稳定性能。

四、封装与装配要点

  • 1206 尺寸适合自动贴装与回流焊工艺;由于为小型 SMD,建议在元件取放与贴装过程中注意机械应力,避免过度挤压透镜或焊膏挤出。
  • 回流焊工艺:遵循厂商推荐的回流曲线;一般情况下采用无铅回流时峰值温度不超过 260 ℃,在回流过程中注意总体升温速率与在液相温度范围内的时间以防止热损伤。请以 EVERLIGHT 最新 datasheet 中的回流规范为准。
  • 极性标识:实际 PCB 设计时请参考器件数据手册中的极性标记和焊盘尺寸,以确保正负极方向正确。

五、可靠性与使用环境

  • 工作温度范围宽(-40 ℃ 至 +85 ℃),适合户内及工业环境的常规指示使用。
  • 推荐储存及防护:避免潮湿、避免强酸/强碱及有腐蚀性气体环境,建议干燥包装下保存并遵循防潮回流焊前的烘烤建议(若为潮湿敏感级别器件)。
  • 静电防护:LED 对静电敏感,使用和检验过程中请佩戴防静电设备并采取相应防护措施。

六、典型应用场景

  • 工业与民用面板指示灯、按键指示
  • 仪表、医疗设备状态显示(非主照明)
  • 家用电器指示、玩具与装饰照明点缀
  • 小型背光与标识灯

七、选型与采购建议

  • 在批量选型时注意光强与色温分档(bin)要求,以保证整机外观一致性;若对色彩一致性敏感建议向供应商确认色彩分档信息并索取样片。
  • 设计样机阶段宜做温升与寿命测试,验证在目标应用下的光衰与可靠性表现。

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
