WS2813B-B可编程RGB LED产品概述

一、基础属性与封装设计

WS2813B-B是worldsemi品牌推出的可编程SMD RGB LED,采用行业通用的SMD5050封装(PLCC6引脚结构),尺寸为5.0×5.0×1.6mm,满足小型化、高密度集成的设计需求。透镜采用透明材质,透光率高且色彩还原度好;产品为三色版本,集成红(R)、绿(G)、蓝(B)三原色LED芯片,是全彩显示与氛围照明的核心基础器件。

二、光学性能参数

该产品光学参数经过精准调校,覆盖人眼视觉敏感的三原色区间:

  • 波长一致性:红光620nm625nm、绿光515nm525nm、蓝光465nm~475nm,波长偏差控制在±2nm以内,色彩饱和度高;
  • 发光强度:绿光典型值1150mcd(同封装中亮度突出,适合醒目标识),红光典型值360mcd、最大值380mcd,蓝光典型值220mcd,亮度满足室内外中等场景需求;
  • 发光视角:透明透镜搭配SMD5050封装,默认视角约120°,发光均匀无暗区,视觉体验佳。

三、电气与传输特性

作为可编程LED,WS2813B-B内置控制IC,具备高效稳定的电气性能:

  • 数据传输:支持单线数字传输,数据速率可达800Kbit/s,兼容主流RGB LED控制协议(如WS2812系列),级联稳定性强;
  • 功耗表现:静态电流仅0.7mA(低待机功耗),工作电压为5V(行业标准),单灯珠工作电流约20mA(典型值),能效优异;
  • 温宽范围:工作温度覆盖**-25℃~+85℃**,可适应低温户外、高温车载等复杂环境,长期可靠性高。

四、可编程控制优势

WS2813B-B的核心优势在于内置独立控制IC,无需额外驱动电路:

  • 像素级全彩控制:每个灯珠可独立调节三原色亮度,实现1670万色全彩显示(24位色深),色彩渐变自然流畅;
  • 级联便捷性:支持多灯珠级联(单控制器可驱动数百至上千个灯珠),布线仅需电源、数据、地三线,大幅降低系统设计复杂度;
  • 兼容性强:可搭配STM32、Arduino等通用MCU,或专用LED控制器,适配不同场景的控制需求。

五、典型应用场景

结合其封装、光学与可编程特性,WS2813B-B适用于以下场景:

  1. LED灯带/灯条:室内氛围灯、户外装饰灯带(宽温适配低温环境);
  2. 小型显示模块:桌面屏、广告灯箱、智能镜辅助显示;
  3. 智能照明:可调色台灯、场景化照明(如客厅、卧室氛围调节);
  4. 车载应用:车内氛围灯、仪表盘状态指示(小尺寸+宽温适配车载环境);
  5. 工业指示:设备状态灯、小型信号塔(高亮度绿光适合醒目标识)。

六、可靠性与工艺特点

  • 封装可靠性:PLCC6引脚设计,回流焊兼容性好,焊接牢固,抗振动性能佳;
  • 材料稳定性:芯片与透镜采用耐高温、抗老化材料,长期使用光衰控制在10%以内(1000小时测试);
  • 批量一致性:批量产品的波长、亮度偏差控制在±5%以内,适合大规模集成应用。

WS2813B-B凭借小尺寸、可编程、宽温稳定等特性,成为消费电子、智能照明、车载等领域的高性价比RGB LED选择。

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
