Kingbright WP937EGW 双色LED产品概述
一、产品定位与封装特性
Kingbright WP937EGW是一款T-1（3mm）标准通孔封装的双色指示灯LED，专为需要双状态视觉提示的场景设计，可同时实现黄绿色与红色两种发光效果。产品搭配雾状白色透镜，兼顾发光均匀性与视觉辨识度，无需额外光学配件即可满足多数指示需求。作为Kingbright的经典通用型LED，其封装符合工业级通孔安装规范，适配各类PCB板的标准焊盘设计，安装便捷且机械可靠性高。
二、核心电光学参数详解
WP937EGW的参数针对双色指示场景优化，关键指标清晰稳定：
1. 正向电参数
- 正向电流（If）：额定值20mA，是LED指示场景的通用工作电流，避免过流导致的器件老化；
- 正向压降（Vf）：红色发光时Vf=2.0V，黄绿色发光时Vf=2.2V，压降差异可通过简单电阻匹配实现独立控制；
- 功率消耗：红色75mW、黄绿色62.5mW，低功耗设计适合电池供电或低功耗设备。
2. 光学特性
- 波长与峰值波长：黄绿色主波长568nm、峰值565nm，红色主波长617nm、峰值627nm，色彩辨识度高，无明显色偏；
- 发光强度：两种颜色均为14mcd，亮度适中——既避免过亮刺眼，又能在普通环境下清晰识别；
- 发光角度：60°广角设计，确保从多方位均可观察到指示状态，无需正对器件。
三、典型应用场景
WP937EGW的双色特性适配多种场景：
- 电子设备状态指示：小家电（电饭煲、加湿器）的“待机/工作”“正常/故障”提示；
- 工业控制模块：PLC、传感器、继电器的“信号通断”“设备就绪/异常”指示；
- 消费电子配件：遥控器、电子秤、玩具的功能状态提示；
- 小型仪器仪表：万用表、示波器的“量程切换”“测量状态”指示。
四、可靠性与环境适应性
- 宽温工作范围：-40℃~+85℃，覆盖工业级与消费级设备的典型温度，可在北方户外、厨房电器等场景稳定运行；
- 通孔封装优势：相比贴片，通孔焊接的机械强度更高，抗振动、抗冲击能力更强，适合长期稳定运行的设备；
- 长寿命设计：低功耗、小电流模式下，器件寿命可达数万小时，无需频繁更换。
五、安装与使用注意事项
为确保稳定工作，需注意：
- 电流限制：实际电流不得超20mA，需串联限流电阻（如5V电源下，红色需150Ω、黄绿色需140Ω）；
- 焊接规范：温度不超260℃，焊接时间≤3秒，避免高温损坏；
- 静电防护：LED对静电敏感，操作需戴防静电手环或用防静电工具；
- 极性识别：长脚为正、短脚为负（或通过封装标识判断），反向焊接易击穿。
总结：Kingbright WP937EGW作为高性价比双色T-1通孔LED，凭借清晰的双色指示、稳定参数与宽温适应性，成为各类设备状态提示的理想选择，覆盖消费电子到工业控制多领域。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
