DALI D4i技术解析:智能照明界新宠,您跟上潮流了吗?

2024/6/27

Exploring DALI D4i: The Latest Trend in Smart Lighting–Are You Up to Date?

光亚展不仅是照明产品的璀璨舞台,更是新技术交流的璀璨盛会。回顾刚刚结束的2024年光亚展,哪些新兴趋势跃然眼前?相较于去年零星的亮相,今年D4iNFCZHAGACASAMBI、米家智联、Matter等产品在展会上频频亮相,备受瞩目。这些名词频繁被客户提及却又似乎不甚了解?那么,这些名词究竟代表着什么?它们在照明应用中又发挥着怎样的作用呢?

The GILE is more than just a showcase for dazzling lighting products; it's a vibrant platform for the latest technology exchanges. Looking back at the recently concluded 2024 GILE, what new trends stood out? Unlike their sporadic appearances last year, technologies like D4i, NFC, Zhaga, Casambi, Xiaomi Smart Home, and Matter were prominently featured and attracted significant attention this year. These terms are frequently mentioned by customers but seem to lack clear understanding. So, what do these technologies represent, and what roles do they play in lighting applications?

秉承以客户为中心的理念,为了增进大家对智能照明现状及技术的了解,莱福德将陆续分享一些前沿智能技术与功能的深入解析。在本文中,我们将用4~5分钟的时间,为大家详细解读什么是D4i

Embracing a customer-first philosophy, Lifud will share in-depth insights into cutting-edge intelligent technologies and features to enhance understanding of the current state of smart lighting and its technologies. In this article, we will take 4-5 minutes to explain what D4i is in detail.

DALI、DALI-2与D4i


DALI, DALI-2, and D4i

DALI是照明控制设备之间双向数字通信的行业标准协议(语言)DALI协议在由多个部分组成的国际标准IEC 62386以及DALI联盟编写的规范中进行了规定。关于DALI的详细解析可查看莱福德往期分享《建议收藏!全面认识DALI调光系统》
DALI is an industry-standard protocol (language) for bidirectional digital communication between lighting control devices. The DALI protocol is specified in the international standard IEC 62386, which consists of multiple parts, and in the guidelines provided by the DALI Alliance. For a detailed analysis of DALI, please refer to Lifud’s previous article, “Recommended to Bookmark! A Comprehensive Introduction to the DALI Dimming System.”

DALI-2是目前最新的DALI协议版本,相比DALI version-1版本,进行了许多改进,规范了更严格全面的测试程序,增强了产品的互操作性并扩展了新的功能命令。

DALI-2 is the latest version of the DALI protocol, featuring many improvements over DALI version-1. It includes more stringent and comprehensive testing procedures, enhances product interoperability, and introduces new functional commands.

D4i技术是基于DALI-2协议的扩展,专为智能物联网(IoT)照明设计。它不仅继承了DALI-2的所有优点,更增加了对数据相关功能的支持,如灯具资产、能耗使用和诊断数据的收集与分析。

D4i technology is an extension of the DALI-2 protocol, specifically designed for smart IoT (Internet of Things) lighting. It not only inherits all the advantages of DALI-2 but also adds support for data-related features, such as the collection and analysis of luminaire asset, energy usage, and diagnostic data.

也就是说,所有的 D4i 认证产品也都是 DALI-2 认证产品,这些产品可以选择放置 D4i 标识或者 DALI-2 标识,也可以两者都放。

This means that all D4i-certified products are also DALI-2 certified. These products can display either the D4i logo, the DALI-2 logo, or both.

D4i技术的优势


Advantages of D4i Technology

1、集成DALI总线:该功能可开启也可禁用,简化系统实现即插即用。

2、在传统DALI-2的应用中,总是伴随着 DALI 总线将多个DALI设备连接起来才能成为一个DALI系统,而D4i则将总线集成在了驱动内部,也就是一个应用D4i驱动的灯具可以自成系统。

1. Integrated DALI Bus: This feature can be enabled or disabled, simplifying the system for plug-and-play functionality.

2. Self-Contained Systems: Traditionally, DALI-2 applications require a DALI bus to connect multiple DALI devices into a system. D4i integrates the bus within the driver, allowing a luminaire with a D4i driver to function as a standalone system.

3、灯具资产数据收集:储存和灯具相关的数据,帮助用户了解产品信息。

如灯具生产厂家的GTIN码、生产日期、色温、标称输入功率等,便于产品追溯和后期维护。

3. Luminaire Asset Data Collection: This feature stores detailed luminaire information, assisting users in understanding product details. Data includes manufacturer’s GTIN code, production date, color temperature, and nominal input power, aiding in product traceability and maintenance.

4、能耗监测:读取灯具运行的能耗数据,帮助用户了解并优化能源使用。

例如如灯具消耗了多少电(理论值=电源输出),电源消耗了多少电(理论值=输出/效率),电网提供了多少电(理论值=电源耗电/PF)等。

4.Energy Monitoring: Reads the luminaire's energy consumption data to help users understand and optimize energy usage.
Examples include:

5、诊断与维护:诊断电源和灯具运行状态,读取维护数据,实现数据化管理。

如看驱动电源是否输入欠压、输入过压、过温以及故障次数;看灯具是否短路、开路、过载、过温以及故障次数等。

5. Diagnostics and Maintenance: Monitors the operating status of the driver and luminaire, reads maintenance data, and enables data-driven management.

Examples include: Driver Diagnostics: Checks for issues such as input undervoltage, input overvoltage, overheating, and counts the number of faults.

Luminaire Diagnostics: Checks for conditions such as short circuits, open circuits, overloads, overheating, and counts the number of faults.

6、24V辅助源:非D4i产品必备功能,可选项。

D4i还定义了和传感器、无线模块之间的接口(要求典型电压24vdc125mA 辅助电源,平均功率为 3W,峰值功率为 6W),可提高应用可靠性,并方便外接模块。

6. 24V Auxiliary Power Supply: This is not a mandatory feature for D4i products but an optional one.

D4i also defines interfaces with sensors and wireless modules, requiring a typical voltage of 24V DC and an auxiliary power supply of 125 mA, with an average power of 3W and a peak power of 6W. This enhances application reliability and facilitates the connection of external modules.
