WP934MD/2GD 产品概述

一、产品简介

WP934MD/2GD 是 Kingbright 推出的 3mm 插件型翠绿色(绿翡翠色)指示 LED,标称峰值波长约 565nm,典型发射波长 568nm。该器件以小体积、较窄的发光角度和稳定的电光性能适用于面板指示、信号指示及多种仪器仪表点状显示场合。型号名称中包含 BI-LEVEL 字样,设计上用于常规指示用途;有关是否实现双级发光或引脚结构的具体含义,请在设计前参考原厂详细数据手册确认引脚定义和内部结构。

二、主要参数

  • 发光颜色:翠绿色(Green)
  • 峰值波长:565 nm(典型发光波长:568 nm)
  • 正向电压 Vf:2.2 V(典型)
  • 正向电流 If(最大额定):25 mA
  • 额定功率(耗散):62.5 mW
  • 发光强度(Iv):25 mcd(在指定测试电流下)
  • 发光角度:50°
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 封装形式:插件(3 mm 圆头封装)
  • 品牌:Kingbright

以上参数为典型/额定值,实际设计中请以厂家数据手册为准,并留有裕量以保证可靠性与寿命。

三、典型电路与阻值计算

驱动 LED 时通常使用限流电阻串联,基本公式: R = (Vsup - Vf) / I

推荐驱动电流:为了兼顾亮度与寿命,一般建议在 10–20 mA 范围内工作;25 mA 为最大额定电流,长时间满载工作会降低寿命。

示例计算(以 I = 20 mA 为例,Vf = 2.2 V):

  • 3.3 V 电源:R = (3.3 − 2.2) / 0.02 = 55 Ω → 选用标准阻值 56 Ω
  • 5 V 电源:R = (5 − 2.2) / 0.02 = 140 Ω → 选用 150 Ω
  • 12 V 电源:R = (12 − 2.2) / 0.02 = 490 Ω → 选用 510 Ω

电阻功耗 P = I^2 × R(以 5 V、I=20 mA、R≈150 Ω 为例):P ≈ 0.02^2 × 150 = 0.06 W,建议采用 1/4 W 阻值以保证足够裕量。

若在 25 mA 工作,阻值与功耗相应减少/增加,请在设计时按最大额定值进行热与电流验证。

四、应用场景

  • 面板/机箱指示灯(电源、状态、警示等)
  • 仪器仪表与控制设备的状态反馈
  • 电子玩具、家用电器的指示/装饰灯
  • 点状显示阵列与低功耗信号标识

得益于 50° 的发光角度和中等发光强度(25 mcd),该 LED 更适合近距离点状提示与方向性指示,而不是大面积照明或大视角显示。

五、热、机械与可靠性注意事项

  • 温度影响:LED 的 Vf 与光输出会随结温变化,工作温度越高,通常 Vf 会略降低但光通量会下降。设计时应预留温升裕量,并保证良好的散热环境。
  • 驱动电流:尽量避免长期在最大额定电流 25 mA 长期驱动,以延长寿命并降低光衰速率。
  • ESD 防护:LED 对静电敏感,焊接与装配过程中应采取基本的防静电措施(接地腕带、抗静电台面等)。
  • 焊接温度:插件元件焊接时遵循厂方推荐的焊接条件,避免过高温度或长时间加热导致封装变形或光衰。
  • 存储与保管:避免强光、潮湿和高温环境长期存放,必要时遵循湿敏包装(若适用)及存储规范。

六、选型与封装建议

  • 若设计需要在同一面板上实现不同亮度级别或双输入控制,请务必参考原厂数据手册确认 WP934MD/2GD 的内部引脚与 BI-LEVEL 的具体定义。
  • 在 PCB 布局时,预留足够的引脚间距与孔径以匹配 3 mm 插件封装,并在驱动回路中放置限流电阻和必要的反向保护元件(若电路可能出现反向电压)。
  • 采购时注明型号、颜色和批次要求,并向代理商或 Kingbright 索取最新数据手册以确认机械尺寸、引脚配置与包装形式(直插轴、散装或管装等)。

总结:WP934MD/2GD 为一款典型的 3mm 翠绿色指示 LED,适用于面板和设备指示领域,具有良好的定向发光特性和稳定的电光参数。设计时请合理选择驱动电流与限流元件,并参考厂家资料进行最终尺寸与电气验证。若需要详细的机械尺寸图、引脚图或 I-V 曲线,请索取 Kingbright 官方数据手册。

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.
