Kingbright L-934GD LED指示灯产品概述

一、核心身份与基础定位

Kingbright L-934GD是一款3mm级插件式漫射型黄绿色LED指示灯,属于通用型指示类元器件,专为电子设备、工业控制、消费电子等场景的状态显示设计。其采用标准插件封装,兼顾安装便捷性与可靠性,是替代传统白炽灯指示的高性价比选择,可满足从研发原型到量产设备的多阶段需求。

二、电气性能参数详解

L-934GD的电气参数经过优化,适配主流驱动电路,核心参数如下:

  • 正向压降(Vf):2.2V(典型值,20mA正向电流下),压降稳定且接近通用5V电源的半压,无需复杂升压/降压电路,串联约140Ω限流电阻即可直接驱动;
  • 额定正向电流(If):20mA,为LED最佳工作电流,既保证发光强度稳定,又避免过流导致的光衰或损坏;
  • 功率(P):105mW(20mA×2.2V),低功耗特性适合电池供电设备(如便携式仪器)或低功耗系统;
  • 波长范围:峰值波长565nm,中心波长568nm,属于黄绿色标准区间(区别于纯绿色的520nm左右),视觉辨识度高,不易与红色、蓝色等其他指示色混淆。

三、光学特性与显示效果

作为漫射型LED,L-934GD的光学表现适配通用指示场景:

  • 发光颜色:黄绿色,视觉舒适度佳,长时间观察无刺眼感,适合设备状态的持续监测;
  • 发光强度:20mcd(典型值),在室内/半室外环境下清晰可见,无需额外光学放大组件;
  • 发光角度:60°(半强度角),漫射封装使光线均匀扩散,视角宽广——从侧面30°左右观察仍能清晰识别状态,避免直射型LED的“眩光盲区”;
  • 漫射型优势:光线无明显方向性,嵌入面板后显示均匀,提升设备外观的整洁度与用户体验。

四、机械与封装规格

封装设计适配传统插件工艺,安装便捷且兼容性强:

  • 灯头尺寸:2.9mm圆形灯头(接近3mm标准),符合通用面板开孔尺寸(3mm左右),便于嵌入式安装;
  • 封装类型:插件式(通孔焊接),引脚长度适配标准PCB板,焊接牢固,耐插拔(适合维修场景);
  • 尺寸紧凑:灯头直径2.9mm,整体高度约5mm,不占用小型设备内部的额外空间,适合高密度布局。

五、环境适应性与可靠性

L-934GD具备宽温工作能力,满足多场景的可靠性需求:

  • 工作温度范围:-40℃~+85℃,覆盖工业级环境(如低温户外设备、高温车间)与消费电子日常使用(如车载、家用);
  • 品牌可靠性:Kingbright作为专业LED厂商,产品符合RoHS环保标准,寿命典型值>50000小时,免维护;
  • 抗干扰性:LED无灯丝结构,抗振动、抗冲击能力优于传统白炽灯,适合移动设备(如手持仪器)或振动环境(如工业流水线)。

六、典型应用场景

L-934GD的通用特性使其适用于多种领域:

  1. 电子设备状态指示:路由器、交换机、服务器的电源/运行/故障灯;
  2. 工业控制面板:PLC、传感器、变频器的“运行”“待机”“报警”状态显示;
  3. 消费电子:小家电(豆浆机、加湿器)的功能指示、电源灯;
  4. 车载辅助指示:仪表盘辅助灯、车载充电器状态灯(宽温适配车载环境);
  5. 通信终端:手机基站、无线AP的信号强度指示。

综上,L-934GD以高性价比、稳定性能与宽适应性,成为通用指示场景的主流选择,可有效降低系统设计与维护成本。

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
