XL-4020RGBC-WS2812B 是成兴光(Xinglight)出品的一款表贴式智能发光二极管模组,封装规格约 2×4 mm,外形紧凑(长度 3.95 mm,宽度 1.7 mm,高度 1.95 mm)。模组内置 WS2812B 类型的单线数字驱动芯片,支持逐点寻址的串行控制,适合像素级可控的彩色照明与显示场景。透明透镜与 120° 的发光角度保证了宽广均匀的出光效果,适用于背光、装饰灯带、舞台灯光及智能显示等应用。
XL-4020RGBC-WS2812B 内置单线控制芯片,支持标准 WS2812B 协议,数据传输速率为 800 kbit/s,便于与常见控制器(如 MCU、FPGA、专用 LED 控制器)配合使用。PWM 频率 1.5 kHz 可实现低闪烁感的亮度调制与色彩混合。工作电压宽幅允许在 4.5–5.5V 的电源环境下稳定工作,但为保证显示一致性与寿命,建议在额定 5V 电源并加适当去耦与限流设计。
透明透镜设计配合 120° 发光角度,具备较好的光分布均匀性,适合点阵、灯条及面状背光应用。峰值波长分别在 R:625 nm、G:525 nm、B:470 nm 区间,颜色还原性好,绿色亮度优势明显(600–800 mcd),适合对绿色亮度要求高的场合。小型化封装(3.95×1.7×1.95 mm)便于高密度布局,支持常规表面贴装回流焊工艺。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
