WS2812D-F5 产品概述

一、产品简介

WS2812D-F5 是由 worldsemi 推出的可编程 5mm 插件型 RGB 发光二极管,内置驱动控制电路,支持单线串联控制(数据输入/输出)。该器件将三色 LED 发光单元与智能控制芯片集成于同一封装内,适用于像素级颜色控制和动画显示应用,能够在单一供电线下通过 800Kbit/s 的数据信号实现精细亮度与色彩调节。

二、主要参数

  • 波长范围:
    • 红(R):620 nm ~ 625 nm(峰值 622.5 nm)
    • 绿(G):520 nm ~ 525 nm(峰值 522.5 nm)
    • 蓝(B):465 nm ~ 470 nm(峰值 467.5 nm)
  • 发光强度(典型):G: 4000 mcd;R: 3000 mcd;B: 2500 mcd
  • 工作温度:-25 ℃ ~ +85 ℃
  • 数据速率:800 Kbit/s
  • 工作电压:3.7 V ~ 5.3 V
  • PWM 频率:2 kHz
  • 正向电压范围(单色 LED):
    • R: 1.8 ~ 2.2 V
    • G: 2.8 ~ 3.1 V
    • B: 2.9 ~ 3.2 V
  • 封装形式:插件(D = 5 mm)
  • 引脚数量:4(VCC、GND、DIN、DOUT)
  • 品牌:worldsemi

三、电气特性与接口说明

  • 接口:四引脚设计,通常排列为 VCC(供电)、GND(接地)、DIN(数据输入)、DOUT(数据输出),支持链式级联,多个 WS2812D-F5 可通过 DOUT 串联到下一个器件的 DIN。
  • 电源范围:推荐在 3.7 V 至 5.3 V 范围内工作,典型应用以 5 V 供电最为常见,确保稳定电源与良好旁路去耦以降低数据误码与亮度波动。
  • 数据要求:支持 800 Kbit/s 的单线串行数据协议,内置 PWM 驱动对 RGB 三色进行细分占空比调节,PWM 基频为 2 kHz。

四、光学特性

  • 三色峰值波长和亮度参数适用于视觉显示与装饰照明场景,绿色通道亮度最高,可用于提高白光混合时的亮度均衡。
  • 典型亮度值为参考值,实际亮度受驱动电流、温度与封装差异影响;在设计显示效果时应考虑色彩校准与亮度一致性。

五、驱动与数据协议

  • 内置可编程控制器直接接收单线串行数据,通过 PWM 控制三色子像素的亮度,实现 24-bit(或可编程位深)颜色输出(具体位深与命令格式请参照 worldsemi 的通讯协议文档)。
  • 支持级联连接,便于构建长串像素链;链路设计时需考虑数据线走线完整性和串间延迟。
  • 建议在数据线入口处加入适当电阻与 TVS 或瞬态抑制器以提高抗干扰能力(具体元件选型依据系统环境而定)。

六、封装与机械信息

  • 5mm 圆头插件式封装,便于手工/自动插件焊接与更换,适配常见面包板与插座布局。
  • 四引脚排列利于插装与信号走线,安装时请注意方向与极性标识,避免反接导致损坏。

七、应用场景

  • 可编程灯带、像素点阵屏、装饰照明、可穿戴设备指示灯、互动艺术装置、舞台灯光与标识灯等需要单像素独立驱动与颜色控制的场合。
  • 适合需要链式扩展、对每个像素进行独立动画与色彩控制的项目开发。

八、使用建议与注意事项

  • 电源稳定性:使用低纹波的稳压电源并在 VCC 与 GND 之间放置强旁路电容(例如 0.1 μF 与 10 μF 组合)以降低瞬态干扰。
  • 布线与终端:长距离数据线建议使用适配的抗干扰措施,必要时在数据线前端增加小阻值串联限流电阻。
  • ESD 与反接保护:在装配与调试中注意静电防护,避免反向连接电源导致芯片损坏。
  • 热管理:在高亮度、长时间点亮条件下注意散热与环境温度,超过工作温度可能影响寿命与色彩稳定性。

九、可靠性与环境适应性

  • 适用工作温度范围为 -25 ℃ 至 +85 ℃,符合常见室内与许多户外环境应用,但在极端温度或潮湿环境下建议进行相应密封与防护处理。
  • 推荐在实际应用前进行环境应力测试(温度循环、湿热测试)以验证长期可靠性和颜色一致性。

十、包装与选型提示

  • 作为插件封装的可编程 RGB 器件,选型时请确认供电电压、控制器兼容性与所需的亮度/色彩规格;批量采购时可与供应商确认光学一致性分级与出货测试报告。
  • 如需详细协议时序图、命令集或参考电路,请向 worldsemi 或正规渠道索取 WS2812D 系列技术手册与应用笔记。

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
