WS2815B-2121 产品概述

一、产品简介

WS2815B-2121 是 worldsemi 推出的一款智能外控全彩 LED 器件,封装为 SMD2121-6P,外形与常见的 2121 封装灯珠相同。每个器件集成控制电路与发光电路为一个像素点,内部包含数据锁存、信号整形、放大驱动、高精度内部振荡器和恒流控制模块,能在外部控制下实现高一致性的颜色显示与稳定亮度输出,适用于高密度点光源、像素化灯带与显示装置等应用。

二、主要特性

  • 集成控制与发光电路,单点即为独立像素。
  • 高精度内部振荡器与恒流控制,保证像素间颜色与亮度一致性。
  • 支持外部数据控制,数据速率:800 Kbit/s。
  • PWM 调制频率:4 kHz,适合肉眼无频闪显示与亮度调节。
  • 工作电压:12 V,静态待机电流:2 mA(典型)。
  • 工作温度范围:-40 ℃ ~ +65 ℃,适应室内外常见环境。
  • 载带方式:正贴,适配自动贴装生产线。

三、电学与光学参数

  • 发光波长:B 465 nm ~ 475 nm;G 510 nm ~ 520 nm;R 620 nm ~ 630 nm。
  • 发光强度(单色典型范围):R 200 mcd ~ 400 mcd;B 150 mcd ~ 300 mcd;G 600 mcd ~ 1000 mcd。
  • 数据传输:单线串行数据,速率 800 Kbit/s(与主控器兼容性需确认)。
  • PWM 频率:4 kHz(用于亮度/灰度控制)。
    注:更详细的电流-亮度曲线、色坐标与驱动电流参数,请参照厂方数据手册。

四、封装与尺寸

  • 封装型号:SMD2121-6P。
  • 外形尺寸:长 2.2 mm × 宽 2.2 mm × 高 1.05 mm。
  • 载带为正贴(适用于常规贴片机)。
    实际焊盘尺寸与引脚分配请以 worldsemi 提供的封装图与 PCB 布局建议为准。

五、使用建议与注意事项

  • 电源:设计 12 V 稳定供电,考虑整条带或像素矩阵的整流与降压保护;建议在电源入口处添加足够的去耦电容以抑制瞬态。
  • 数据:保证数据线完整性与匹配,数据速率为 800 Kbit/s,长线传输或多级驱动时注意信号完整性与参考接地。
  • PWM:当使用 PWM 调光时,按 4 kHz 工作频率设计驱动与滤波,避免与外部采样或感光设备干涉。
  • 散热与可靠性:封装小巧,单点热阻相对较高;在高亮度长期工作场景下应做好散热与间距管理。
  • ESD 与焊接:遵循常规 SMT 工艺与静电防护;贴装与回流焊工艺参数请参考厂方推荐曲线。
  • 环境:工作温度 -40 ℃ ~ +65 ℃;超出范围可能影响寿命与发光一致性。
  • 引脚定义与接线:典型有 VCC、GND、DATA_IN、DATA_OUT 等功能引脚,最终接线请参考 worldsemi 官方资料与原理图。

六、典型应用场景

  • 像素化灯带、点阵屏与装饰性照明。
  • 建筑轮廓照明、舞台灯光与商业展示。
  • 智能家居氛围灯、背光与信号指示。
  • 可编程光艺术装置与互动显示。

七、采购与支持

  • 品牌:worldsemi。型号标识:WS2815B-2121,封装 SMD2121-6P。
  • 订购与技术支持建议直接联系厂家或授权分销商,获取最新版数据手册、封装图纸与可靠性测试报告,以便在量产阶段完成验证与匹配设计。

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
