简介

数字可寻址照明接口 (DALI) 在家庭和建筑照明应用中越来越受欢迎。该标准可以使用简单的接线和选项来更改配置。最新的 DALI 2.0 标准允许用户控制多达 65 个单独的灯和/或 32 组灯。如今,可以通过 DALI 轻松设置使用多个照明设备的复杂彩色灯光场景。该参考设计使用了节能 LED,通常以灯条形式排列。对于环境照明,首选 RGB;但对于常规照明,则需要使用暖/冷白光。

瑞萨电子提供了一种高度集成的完整解决方案,可驱动五个 LED 灯条,分别是红色、绿色、蓝色、暖/冷白光,每个灯条电压可达 70V,电流可达 700mA,从而产生 245W 的 LED 总功率。超出 24VDC 输入情况下,可以内部升压至 70V。

瑞萨电子的 Synergy S128 微控制器 (MCU) 已经包含了 DALI 2.0 专用的外部设备,因此 BOM 总数进一步减少。瑞萨电子还提供了一流的电源解决方案,以在标准 24VDC 之外运行系统。

系统优势:

  • RGBWW 驱动器适用于高达 5* 70V/700mA = 245W LED ~ 25.000 Lumen
  • 多种接口,包括 DALI 2.0 接口(S128 MCU 中包含的外部设备)、RS-485 接口以及 PMOD 适配器,以添加无线连接(例如: 蓝牙或 Wi-Fi)——全部采用 24VDC 电源且 BOM 数量少
