WS2815C-2020-4P 产品概述

一、产品简介

WS2815C-2020-4P 是 worldsemi 推出的智能外控 LED 器件,将控制电路与发光电路高度集成于 2mm 级别的小型封装内。外形等同于 2020 型号 LED(约 2×2×2mm),每个元件即为一个独立像素点。像素内部集成了数据锁存、信号整形放大、高精度内部振荡器和恒流控制模块,可在外部时钟与数据驱动下实现稳定、可寻址的彩色显示效果,适合像素化矩阵、灯带与装饰照明等应用场景。

二、核心性能亮点

  • 高度集成:控制电路与发光单元一体化,减小系统设计复杂度与占板面积。
  • 色彩一致性:内部高精度恒流控制与振荡器,保证像素点间颜色一致性与稳定性。
  • 外控灵活:支持 800 Kbit/s 数据速率的串行数字接口,便于与常用控制器配合。
  • 宽电压工作:工作电压范围 9.5V ~ 13.5V(典型 12V 系统兼容),便于在多种供电方案下使用。
  • 小型化封装:SMD-4P,典型尺寸 2.0 × 2.0 × 2.0 mm(封装参数标注为 2.2 × 2 mm),适合高密度贴装。

三、主要电气与光学参数

  • 波长(典型范围)
    • 蓝色 (B):467 nm ~ 471 nm
    • 绿色 (G):518 nm ~ 523 nm
    • 红色 (R):627 nm ~ 632 nm
  • 发光强度(典型)
    • R:45 mcd
    • G:140 mcd
    • B:35 mcd
  • PWM 调制频率:4 kHz(用于亮度与色彩混合的脉冲宽度调制)
  • 数据传输速率:800 Kbit/s(单线串行数据接口)
  • 静态电流(待机):2 mA
  • 工作电压:9.5 V ~ 13.5 V
  • 工作温度:-40 ℃ ~ +65 ℃

注:上述发光强度为典型值,实际显示亮度受驱动电流、封装与印刷板条件影响。

四、封装与机械信息

  • 封装形式:SMD-4P(表面贴装,4 引脚)
  • 尺寸:2.0 × 2.0 × 2.0 mm(封装标注 2.2 × 2 mm,具体尺寸请参考厂商封装图纸)
  • 每个像素包含完整驱动与发光单元,便于串联拼接与模块化设计。

五、应用场景

  • 像素化灯条与灯带(12V 系统)
  • 灯光装饰、广告招牌与轮廓照明
  • 可编程背光、舞台灯光与互动装置
  • 智能家居氛围灯与户外景观灯(在符合防护要求下)

六、设计与使用建议

  • 电源设计:器件允许 9.5V~13.5V 工作。建议采用稳定的直流电源,并在长距离布线或大量像素时考虑分段电源注入以降低压降。
  • 去耦与保护:在电源入口处增加适量去耦电容(如 100 μF 级与 0.1 μF 并联)以抑制瞬态,必要时加入保险与过压保护电路。
  • 信号完整性:数据速率 800 Kbit/s,建议保持良好走线、避免长距离无屏蔽直连;在需要时增加信号缓冲或使用差分/抗干扰手段。
  • PWM 与刷新:内置 PWM 工作在 4 kHz,可与控制器的亮度控制相配合以获得平滑的颜色过渡。
  • 热管理:虽然单颗器件功耗较低,但在密集排列或高亮度连续点亮时仍需注意散热与温升。
  • SMT 与焊接:遵循常规 SMT 回流焊工艺与 ESD 防护规范,避免静电损伤器件。具体回流曲线与工艺参数请参照 worldsemi 官方资料。

七、可靠性与注意事项

  • 工作温度范围 -40 ℃~+65 ℃ 能满足常见室内与部分户外环境,但在严苛高温或潮湿环境需采取防护处理(如涂覆、封装或防护胶)。
  • 静态待机电流为 2 mA,系统空闲时仍有微量耗电,长时间断电或休眠场合请通过外部电源控制实现节能。
  • 器件为精密半导体组件,避免在不良焊接、过压或静电环境中直接使用。

八、结语

WS2815C-2020-4P 以其小尺寸、高度集成与良好的色彩一致性,适合对像素密度与视觉效果要求较高的智能照明与显示应用。为获得最佳性能,推荐在设计初期参考 worldsemi 的详细技术资料与封装图,并在实际项目中做必要的电源与信号完整性验证。若需技术资料(数据手册、封装图)或样品支持,可联系供应商获取官方资料。

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
