WorldSemi WS2850B 5×5mm SMD全彩LED产品概述

WS2850B是WorldSemi推出的一款5×5mm贴片式(SMD)全彩LED,采用独立二极管配置,针对室内中等亮度显示、装饰照明等场景优化设计,兼具宽视角、稳定电气性能与良好环境适应性,适合批量自动化生产。

一、显示性能参数详解

WS2850B的三基色波长均处于人眼视觉敏感的常规全彩范围,色彩还原准确:

  • 红色(R):621nm(暖红光,饱和度适中,适合文字/图形显示)
  • 绿色(G):518nm(纯绿光,亮度表现突出,符合人眼对绿光更敏感的视觉特性)
  • 蓝色(B):471nm(蓝光,色彩纯净,支撑丰富的冷色调显示)

发光强度梯度设计合理,满足室内场景的亮度需求:

  • 绿色最高达1500mcd(约1.5cd),是红色的2倍左右、蓝色的4倍左右,三基色亮度匹配度良好,无需额外复杂的亮度补偿
  • 红色700-750mcd、蓝色320-350mcd,亮度清晰且不刺眼,适合近距离观看

发光角度达120°,属于宽视角设计,可覆盖较大的观看范围,边缘区域无明显暗区,适合多人同时观看的小型显示场景。

二、电气与功率特性

WS2850B的电气参数统一且稳定,便于驱动电路设计:

  • 正向电流(If):三基色均为20mA(常规LED驱动电流,无需特殊升压/降压设计,可兼容常见驱动芯片)
  • 正向压降(Vf):红色2.0V(典型低压降值,降低功耗),绿色与蓝色均为3.2V(压降一致性好,批量应用时参数稳定)
  • 功率:红色75mW,绿色与蓝色100mW,功率适中,工作时发热低,可简化散热设计,提升产品可靠性

各参数的一致性较好,批量生产时无需频繁调整驱动参数,有效提升生产效率。

三、封装与环境适应性

WS2850B采用5×5mm SMD封装,具有以下实用优势:

  • 贴片式设计:适配自动化贴装设备,支持高速批量生产,降低人工成本
  • 小型化尺寸:5×5mm的紧凑尺寸,可在有限空间内实现较高的集成密度,适合小型显示模块(如柜台屏、玩具发光模块)
  • 宽温工作范围:-40℃~+65℃,可适应寒冷地区(如北方冬季室内)、常规室内环境(25℃左右)及部分高温场景(如夏季室内),环境适应性强

四、典型应用场景

结合WS2850B的性能参数,其主要适用场景包括:

  1. 室内小型电子显示屏:会议室信息屏、商店小型招牌、柜台展示屏等,宽视角与适中亮度满足近距离观看需求
  2. 装饰照明:节日氛围灯、室内装饰灯串、小型景观灯等,三基色可实现丰富的色彩变化
  3. 状态指示设备:家电控制面板、小型仪器状态显示等,亮度清晰且不刺眼
  4. 小型电子产品:儿童玩具的发光模块、小型电子礼品的显示部分等,紧凑尺寸适配小空间设计

五、总结

WS2850B作为一款中等亮度的5×5mm SMD全彩LED,平衡了显示性能、电气可靠性与应用成本,独立二极管配置确保各颜色独立控制,宽视角与宽温范围拓展了应用场景,适合对亮度要求不极端、需要稳定显示效果的室内应用。其贴片封装特性也使其成为批量生产的理想选择,可满足不同行业的中小型显示/照明需求。

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
