WP934AD/GD 产品概述

一、产品简介

WP934AD/GD 是 Kingbright 的翠绿色(雾状绿色透镜)直插式右角发光二极管,典型用于面板指示、板上状态显示及各种电子设备视觉提示。峰值波长为 568 nm,呈现明亮的翠绿色光色,透镜为雾状设计,可提供均匀的漫散射视感,适合近距离观察及角度可视性要求较高的场合。

二、电光主要参数

  • 发光颜色:翠绿色
  • 峰值波长:568 nm(典型)
  • 正向电压 Vf:2.0 V(典型)
  • 正向电流 If:25 mA(额定)
  • 发光强度:25 mcd(If=25 mA,典型)
  • 发光角度:50°(典型)
  • 标称功率:62.5 mW(厂商给出);按 Vf×If 计算典型消耗约 50 mW(2.0 V × 25 mA)
  • 工作温度:-40 ℃ 至 +85 ℃

三、机械与封装特性

WP934AD/GD 为右角插件(through-hole)封装,适合 PCB 垂直/平行布板以改变观察方向。雾状绿色透镜有助于降低眩光并扩大视角,便于近距离观察时得到均匀光斑。安装时注意确保透镜方向与面板开孔或观察方向一致,焊接后避免对透镜与导线施加机械应力。

四、驱动与典型电路

本器件建议恒定电流驱动或在电源端串联限流电阻:

  • 电阻计算:R = (Vsup − Vf) / If
  • 例:5 V 电源时 R ≈ (5 − 2.0) / 0.025 = 120 Ω,耗散功率 P_R ≈ (Vsup − Vf)×If = 3 V×0.025 A = 0.075 W,选用 1/4 W 或更高功率电阻;
    12 V 电源时 R ≈ 400 Ω,电阻耗散约 0.25 W,建议 1/2 W 电阻。
    推荐使用恒流驱动器以获得稳定亮度与长寿命;PWM 调光时注意开关频率与占空比,以避免可见闪烁或驱动过冲。

五、热管理与可靠性

器件自身功耗较低,但长期在高温环境(靠近 85 ℃)下工作应适当降额(降低 If)以延长寿命。装配过程中遵循制造商焊接规范:手工焊接建议快速点焊、峰值温度与时间应控制在合适范围(参照 Kingbright 数据表)。运输与装配时注意静电防护(ESD),避免直接接触发光面与焊点过热。

六、典型应用场景

  • 仪器仪表指示灯、面板状态指示
  • 家电指示、键帽背光(低亮度提示)
  • 通信设备、网络设备面板状态显示
  • 位置指示与工业控制信号灯

七、注意事项与选型建议

  • 请以 Kingbright 官方数据表为最终依据,器件焊接参数、绝对最大额定值应参照原厂。
  • 若需要更高亮度或更大发光角度,可考虑并联多颗或更大功率型号,但必须保证每颗 LED 的限流与散热。
  • 对于严格色度一致性或批次间一致性要求高的应用,建议向供货商索取同一批次(bin)器件或进行色彩筛选。

总结:WP934AD/GD 以其翠绿色、雾状透镜和右角插件结构,在需要方向性、均匀光斑和可靠指示的场合表现优秀。合理驱动和良好装配可确保稳定的光学性能与长久可靠性。

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
