ZGSM street lights with Zhaga-D4i

Street lighting is the main component of urban lighting. Its lighting effect (brightness and illumination) and quality (uniformity and glare) are directly related to the city’s nighttime safety and quality of life. With the progress of LED technology in light efficiency, LED is increasingly used in road lighting due to its energy-saving characteristics. How can LED lamps achieve further energy saving and application? The answer is intelligent control. In the early years, we may have heard of Zigbee, LoRa, NB-IoT, etc., which are currently more mature and applied technologies. They mainly rely on the NEMA interface ( Why care about NEMA enclosure types and lP ratings? ) to control street lights and process some lamp data. In recent years, Zhaga and D4i have proposed Zhaga-D4i, which not only has intelligent control but also requires data transmission. Most street lights of ZGSM are honored to have passed the Zhaga-D4i certification this year. Here, we will mainly introduce what Zhaga-D4i is, as well as the street lights certified by ZGSM through Zhaga-D4i and their applications.

What’s Zhaga-D4i?

Zhaga-D4i is a standard for smart lighting and Internet of Things (IoT) connectivity, developed by the Zhaga Alliance and the DALI Alliance. The standard aims to ensure mechanical and electrical interoperability and interchangeability between luminaires and control devices, and promote the deployment of smart connected lighting systems. To understand clearly, we need to know what Zhaga and D4i stand for. ( View ZGSM LED street light with D4i connection )

Zhaga is actually an organization that defines the standards for the interfaces of key components of LED luminaires, which involve LED modules, lenses, LED drivers, sensors, etc. After the interfaces of these components are standardized, it can improve the mechanical and electrical compatibility and interoperability between products/components from different suppliers. Among them, the standardized interfaces involved in Zhaga-D4i are mainly Zhaga Book 18 and Zhaga Book 20. The former is for outdoor luminaires, namely Book 18-Smart interface between outdoor luminaires and sensing / communication modules. The latter is for indoor luminaires, namely Book 20-Smart interface between indoor luminaires and sensing / communication modules.

D4i is DALI for the IoT as some people say, while others say it is DALI for Intra-Luminaire. It was proposed by the DiiA organization. We are more familiar with DALI (Digital Addressable Lighting Interface) and DALI-2, which is a digital addressable lighting interface standard for smart lighting systems. It allows lighting equipment to communicate and control through digital signals, providing functions such as switching, dimming, and scene setting. D4i is an extension based on DALI. It is not just communication and control between lamps, but also focuses on intelligent communication and control between internal components of lamps (such as LED drivers, sensors, etc.). The D4i standard supports the collection and analysis of data such as lighting assets, energy, and diagnostics, which is a function that DALI-2 does not have. Through the D4i standard, sensors and communication modules can be easily integrated into LED lamps without the need for additional DALI lines. D4i defines a unified communication interface and data format, so that lamps, controllers and sensors produced by different manufacturers can be compatible with each other and realize interconnection between lamps.

So Zhaga-D4i is a lighting interface standard that combines the technologies of the Zhaga Alliance and the DALI (Digital Addressable Lighting Interface) Alliance to provide a standardized solution for data communication between smart LED lamps ( Please review videos of smart street light. ) and sensors/communication modules or controllers.

The benefits of Zhaga-D4i

ZGSM street lights with Zhaga-D4i and their applications

ZGSM has been deeply involved in the field of street lighting for 19 years, and we have developed more than 20 different street lamps. For the hot-selling models, we applied for Zhaga-D4i certification this year. These products can meet most of the application places of public lighting. Below we list ZGSM’s Zhaga-D4i-certified products features and applications one by one.

Rifle series street lights

The Rifle series street lights are ZGSM’s new generation of street lights, using high-efficiency LED chips. The product can be equipped with Zhaga or NEMA sockets, which is convenient for customers to equip the lamps with intelligent lighting control systems in the future. At the same time, the product has passed a series of certifications such as ENEC, CE ( CE lighting certification ), CB, RoHS, ENEC+, etc. to meet the certification requirements of customer projects. ZGSM’s Falcon series street lights have almost the same certifications as the Rifle series, but they have higher luminous efficiency. At present, many customers of ZGSM ( Please review videos of ZGSM street light factory. ) choose these two street lights to bid for government projects, mainly because they are cost-effective and have complete certificate reports.

Nova series street lights

The Nova series LED street lights have a unique visual appearance and reliable performance. It is a modern and beautiful outdoor lighting that can provide continuous and stable lighting for residential streets, sidewalks, parks, playgrounds and other lighting places. At the same time, it has a lightweight design and is a very cost-effective product. However, this product also has complete certifications and is equipped with Zhaga and D4i LED drivers, which is also an ideal street light choice for contractors and end users.

Halo series post top light

Halo series is the second generation LED post top light of ZGSM. Halo can be used as a post top light by the installation method of single arm and double arm, Halo with side entry fitter can be used as a street light. There are also other 3 different installation way to make it suitable for more applications. At the same time, Halo’s design is more linear, and its excellent heat dissipation performance provides customers with a more economical garden light solution. These features make Halo an ideal choice for parking lots, parks, pedestrian streets ( Standard and requirements refers to pedestrian lighting ), city squares or road lighting.

H series street lights

The H series LED street lights were developed in 2013 and have been selling well ever since. They have been sold to more than 100 countries around the world, with sales of 500,000 units. ZGSM believes that the reason for its popularity is its traditional modular design, which is very beneficial for heat dissipation and later maintenance. At the same time, the light source and LED power supply are placed independently, reducing the impact of heat dissipation on each other. The H series can be equipped with Zhaga socket and D4i LED driver to make it Zhaga-D4i certificated.

ZGSM AC street lights can be equipped with a D4i LED power supply. The optional LED driver brands include Inventronics, Philips, Osram, Done, Sosen, and others. Additionally, the lamp can be installed with either one or two Zhaga sockets, adhering to the Zhaga-D4i standard. These features allow ZGSM street lights to carry the Zhaga-D4i logo. Below are some pictures for your reference.

Summary

ZGSM street lights with Zhaga-D4i logo are specially designed to illuminate outdoor areas such as roads, streets, parks, squares and parking lots. Different lamp housings are mostly made of die-cast aluminum, PC lens + glass (some series do not contain glass), and the protection level is IP66 and IK08(or above). All of these lamps (H series, K series, Kmini series, L series, Rifle, Nova, Falcon, Leaf, Halo) can be equipped with D4i LED driver and 1-2 Zhaga sockets, making these lamps more interoperable and future-proof. In addition to Zhaga-D4i certification, our products also have CB, ENEC, ENEC+, RoHS, LM80, LM79, LM82, LM84, IEC62717, IEC62722, TM21, IP/IK, Salt spray and other certifications or test reports to help customers get projects. In addition to Zhaga sockets, our lamps can also be equipped with NEMA ( Watch the video of the Leaf Series streetlights featuring NEMA street light controller ) to make it smart ready.
