Kingbright L-7113SGC 产品概述

一、概述与定位

L-7113SGC 是 Kingbright 推出的黄绿色发光二极管(LED),采用插件(穿孔)封装,透镜为无色透明结构。该器件以窄光束、高亮度为特征,典型应用于指示灯、面板指示、仪表背光以及需要明确指向性的信号显示场合。器件标称工作环境宽,适合工业级温度要求的应用。

二、主要电学与光学参数(关键数值)

  • 发光颜色:黄绿色
  • 峰值波长:565 nm;典型波长:568 nm
  • 典型正向压降(Vf):2.5 V(在正向电流 20 mA 时)
  • 额定正向电流(If):20 mA
  • 发光强度:240 mcd(标称)
  • 发光角度:20°(窄角聚光型)
  • 透镜颜色:无色透明
  • 工作温度范围:-40 ℃ 至 +85 ℃
  • 封装形式:插件(穿孔)
  • 品牌:Kingbright
    说明:按 If = 20 mA 与 Vf = 2.5 V 的乘积,器件在典型工作点的消耗功率约为 50 mW;若资料中列有 62.5 mW 的额定功率,应以厂方数据为准并据此做热设计与使用限制。

三、光学特性与应用建议

L-7113SGC 的 20° 发光角度属于窄束型,能量集中,适合需要清晰指向性的场合,例如:

  • 仪表、控制面板的指示灯;
  • 精密指示位置或状态的视觉信号;
  • 小型光学定位与导引标识。
    黄绿色波段(565–568 nm)在视觉敏感度曲线接近峰值,肉眼感受亮度效率高,因此在相同电流下比部分其他颜色更“亮”。无色透明透镜有助于色温及波长的纯净输出,利于配色控制与视感一致性。

四、驱动与电路设计要点

  • 恒流驱动推荐:为稳定亮度与延长寿命,优先采用恒流源或恒流限制电路;若采用串联限流电阻,应按实际供电电压计算并留有裕量。
  • 限流电阻示例(以 Vf = 2.5 V、If = 20 mA 为基准):
    • 5 V 电源:R = (5 − 2.5) / 0.02 = 125 Ω(可选 120 Ω 或 130 Ω,电阻功率约 0.05 W)
    • 12 V 电源:R = (12 − 2.5) / 0.02 ≈ 475 Ω(可选 470 Ω 或 480 Ω,电阻功率约 0.19 W)
    • 3 V 电源:R = (3 − 2.5) / 0.02 = 25 Ω(电阻功率约 0.01 W)
  • PWM 调光:通过 PWM 控制驱动电流可实现无色偏的亮度调节,但开关频率应高于可见频闪阈值(建议 >1 kHz),且保持峰值电流不超过额定值。
  • 串联/并联注意:多颗串联时须保证总电压余量;并联时每颗建议各自限流或使用恒流分配方案以防不均流。

五、热与可靠性注意事项

  • 工作温度范围为 -40 ℃ 至 +85 ℃,在高温环境下应考虑适当降额(降低正向电流或缩短工作周期)以保证长期可靠性。
  • 虽然 LED 本身发热较小,但长期超过推荐条件(尤其在高 If 和高环境温度下)会加速光输出衰减。实际应用中应关注电路板散热与通风设计。
  • 存储与装配时注意防静电(ESD)防护与避免强烈机械应力以免损坏芯片或引脚焊点。

六、封装与机械安装

L-7113SGC 为插件封装,便于手工或波峰/选择性波峰焊接装配。装配时注意:

  • 插入孔径、引脚间距和贴装方向,确保透镜朝外无遮挡;
  • 焊接温度与时长遵循通用 LED 插件焊接规范,避免过热对塑料透镜和内部胶体的影响。若有严苛的焊接工艺要求,请参阅 Kingbright 官方 Datasheet。

七、典型应用场景与选型建议

推荐用于:工业设备指示、仪器面板、通信设备状态灯、医疗设备指示、消费类电子指示灯等。选型时注意:

  • 若需要更宽角度或更高亮度,请对比 Kingbright 同系列其他型号或高亮度封装;
  • 在高电压或串并联阵列中优先采用恒流驱动以保证光学一致性;
  • 关注温度与环境条件,必要时选择带散热或降额方案的系统设计。

结语:L-7113SGC 以其窄角高亮的黄绿色输出和插件封装,适合需要明确指示方向和高视觉效率的场景。设计时以恒流驱动与热管理为要点,遵循厂方 Datasheet 的极限值和焊接指南,可获得稳定、长期的性能表现。若需更详尽的机械尺寸、可靠性数据或完整电气极限,建议查阅 Kingbright 官方 Datasheet 或联系供应商获取最新版资料。

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.
