Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.The DALI Alliance regularly holds the calls on different committees and working groups, namely the board of directors, technology and certification work groups (T & C WG) and Public Working Group (PWG). T & C working group host face-to-face meetings and “Plugfest” activities. Only the full authority can participate in the working group. All representatives and ordinary members can participate in the DALI Alliance Conference.

Yes, all members of the DALI Alliance need to pay the certification fee for each certification product. Pay in advance by purchasing certification credit points. This is separated from any test costs that member companies must pay independently. The certification fee helps to promote and develop work related to DALI, including: certification technical support; testing and improvement of test sequence software; verification of test results; maintaining online submission systems and product databases, and building new functions; and through market supervision to protect the value of the DALI Alliance and DALI brand.

The DALI-2 certification process is based on the latest version of the DALI protocol, involving the verification of the test results of the DALI Alliance. In contrast, the DALI-1 compliance test is based on self-declaration and does not require verification results. In addition to covering many different product types, including control devices such as input devices and application controllers, the DALI-2 certification also promises to improve the interoperability of different manufacturer products.

No, the certification fee is a one-time fee for each product. Once the product is certified, as long as the company is still a member of the DALI Alliance, it is still certified.

DALI Alliance does not release test reports or product certification documents. Instead, each DALI-2 certified product is listed on the public search page: (www.dali2.org/products). This page can be used to check the DALI-2 certification status: the products that are not displayed in the list have not passed the DALI-2 certification. This is also applicable to DALI-1 registration.

The cost depends on the situation. The DALI-2 certification is only applicable to the full authority or ordinary member of the DALI Alliance, and the annual fee for full or ordinary members is 15,000 euros or 5,000 euros, respectively. Each authentication product needs to purchase certification points in advance. The price is shown in the table as shown below, and the certification process is completed through the certification points. Member companies can buy Probitlab2 hardware and other devices for testing, or when applying for certification on the DALI Alliance website, a third-party institution can be tested and attached a test report.

Certified credit points purchase cost:

1 500 euros

5 2000 euros

20 5000 euros

100 15000 euros

Yes, it is no longer possible to register the DALI-1 control device on the DALI Alliance website. See www.dali-alliance.org/testing/dali-version-html

Yes, all DALI-1 products will be kept visible in the product database (www.dali-alliance.org/products). In addition, according to the DALI Alliance “Trademark Guide” documents, all registered products are still allowed to use DALI trademarks.

The 1st edition of non-DALI standards does not include control devices (including input devices, such as occupying sensors, buttons, etc., and application controllers). Therefore, the DALI-1 logo cannot be used for these products. The DALI-2 certification of the input device has now been launched.

DALI website can be listed on the DALI-1 control device that has not been recognized by DALI-2: https://www.dali-rliance.org/product-info/Control-devices.html

DALI-2 is the latest version of DALI Lighting Control Agreement. DALI-2 includes many new commands and functions, focusing on the interoperability of multi-supplier products. In addition, DALI-2 includes control devices (including input devices such as application controller and sensors) for the first time, which are not part of the DALI-1.

The DALI-2 logo can only be used by members of the DALI Alliance (a complete representative or ordinary member) on products that successfully completed the DALI-2 certification process. All DALI-2 certified products are listed in the product database on the DALI Alliance website. In addition, according to the DALI Alliance trademark guide, the DALI Alliance’s communication members have the right to use the DALI-2 logo on the lamps including DALI-2 certified devices.

Yes, but only when you apply for a communication member qualification, use the certified DALI-2 control devices and control devices in the lamp, and the lamps are registered on the DALI website. License. Lantern manufacturers are communication members who have no registered fees, annual fees and expenses listed on the product website. 

For the DALI control unit (or LED driver or power supply) and control device, D4i is a DALI-2 certification extension. D4i products are DALI-2 products, with a set of specific data support functions. All D4i certification control devices (driving power) and control devices are also certified by DALI-2. These products can be selected using D4i tags, DALI-2 tags, or both.

Data related to asset management, energy use, diagnosis and maintenance can be stored in the memory library of control devices, and these data can be read. For more details, see DALI Consortium Specification Part 251-253.

LED controls need to support components 207 and components 250-253. Auxiliary power function-150 part is optional. In addition, the default state of the integrated bus power must be on. The product must also meet the requirements listed in “D4i certification and trademark use” (download) https://www.dali-rliance.org/specifications/download.html

Yes, the new D4i specification DALI part 351 defines the requirements of D4i for sensors and other control devices.

Use multiple D4i lamps in the same DALI system, please make sure that the bus power current does not exceed the maximum bus allowed range up to 250mA. For example, the maximum bus supply current with a D4i lamp with a control device may be 60mA, and the four such lamps can be connected together on a single DALI bus (the maximum total current power supply is 240 mA). However, if more than four lamps are connected, one or more bus power supply needs to be disabled by configuring the debugging tools. For the configuration of the D4i control unit, the configuration debugging tool can be used before connecting the DALI bus of the lamp to a larger system decoration.

Zhaga-D4i is a joint certification project between Zhaga and DALI (DIIA). Tested and certified by DALI Alliance D4i and passed the Zhaga Book18 or Book20 certification product (lamp or application controller) of the Zhaga Alliance.

The D4i certification is only applicable to members of the DALI Alliance (a complete representative or ordinary member). This means that Zhaga members must also join the DALI Alliance to obtain D4i certification, which is an important first step towards Zhaga-D4i controller certification.

Zhaga members can obtain lamps Zhaga-D4i certification that do not need to join the DALI Alliance (although DALI Alliance Communication Members are free). Lantern manufacturers must be able to prove that their lamps use certified D4i products, such as D4i power supply, D4i controller, etc. Zhaga-D4i certification will check Zhaga during the process of authentication.

The Zhaga-certified Zhaga part is only suitable for Zhaga members (formal or ordinary members). DALI Alliance does not conduct mechanical compatibility inspections. This means that if members of the DALI Alliance with D4i certification control devices want to obtain Zhaga-D4i certification, they must also become a member of Zhaga (full or ordinary members).

DALI Alliance provides D4i protocol certification for all control devices for all DALI (“Lighting Control Control Equipment” specifications). The connector can use the Zhaga connector Book18, NEMA/ANSI, and other connectors, as well as no connectors (only provided cables).

DALI Over Wireless (also known as wireless DALI) to implement DALI lighting control applications on the underlying wireless network. The DALI device on the wireless mesh network is a DALI-based device with wireless communication function. Bridge between wireless to DALI Gateway Bridge connecting wireless DALI networks and wired DALI networks or lamps. Wireless to DALI gateway allows integrated DALI lighting products into existing wireless ecosystems. The gateway is highly transformed between DALI and wireless protocols.

By combining DALI lighting control with wireless communication connections, many different application areas and use cases can be solved. By formulating specifications for DALI wireless and wireless gateway options and participating in multiple wireless agreements, the DALI Alliance is creating necessary standardization to provide options for product developers, customers and other stakeholders.

DALI part 104 and IEC 62386 Standard part 104 is related to DALI Wireless options. Anyone can use part 104, which can be obtained through IEC. Section 104 describes a variety of transmission alternatives (wireless and wired) of traditional wired DALI bus systems. However, part 104 lacks many key details that support interoperability and certification. These details have been changed and added in the new DALI Alliance specification.

The goal of the wireless DALI and wireless DALI gateway promoted by the DALI Alliance is to establish a certification plan with different ecosystem partners. The work is ongoing, but the final timetable of the beginning of the certification is yet to be announced later.

There are many benefits of wireless networks, especially when the lighting is integrated with other building management systems. However, the most widely used wireless protocol has not been developed with lighting. In contrast, DALI is developed for lighting, and has many custom functions related to lighting, color control, sensing, emergency lighting, lamp usability, energy and diagnostic data. DALI is based on global standards. Other protocols do not provide equally rich standardized lighting specific functions.

Section 104 describes a variety of transmission alternatives (wireless and wired) of traditional wired DALI bus systems. A underlying communication protocol in part 104 is the user database protocol (UDP), which is related to the Internet protocol (IP). UDP supports a variety of wired (such as Ethernet) or wireless (such as Thread, WiFi) options. The new specification supports IP-based wireless protocol DALI with Thread. Other protocols may be supported in the future.

Standards promote interoperability, establish market confidence and speed up adoption. DALI wireless gateway solutions have many closed solutions, which aims to act as a gateway between DALI and other wired and wireless protocols. However, if there is no open, industry-defined specification, it is impossible to ensure that these gateways work normally in different environments.

All the tasks of the DALI League in terms of standardization and certification are guided by the usability of priority matters set by our members and the availability of the volunteers who perform the necessary tasks; this includes the formulation of specifications and testing procedures, and the assessment and testing to start certification. For the DALI wireless gateway, our members considered various options and initially decided to cooperate with the ZigBee Alliance and Bluetooth SIG.

The gateway specifications support the definition of good and consistent lighting behavior. DALI is developed for lighting, with many customized lighting control functions, as well as the availability of lamps, energy and diagnostic data. It is important that DALI is based on global standards. Other protocols do not provide equally rich standardized lighting specific functions. In addition, the gateway allows the use of existing DALI products. Especially for the LED control unit, the existing suppliers provide a large number of certified products and provide options for different application scenarios.

“Wireless DALI” is another different solution. Among them, the DALI command is transmitted through wireless carrier, and the network network consists of wireless DALI device. For the gateway, the DALI side is wired, or a single lamp containing a DALI bus inside a lamp, or a wired bus with multiple lamps, not the DALI side is wireless.

The transformation between the wireless to the DALI gateway is a wireless protocol at one end and the wired DALI device on the other end. Wireless device (including gateway) uses a wireless ecosystem protocol to communicate. For DALI+, there is no need to translate, and always use the DALI command. DALI+ combines with wireless operators to achieve a real wireless DALI.

The first version of the new part 104 and supplementing the norm supports IP-based protocols, such as Thread, Ethernet, and Wi-Fi. The specified future version may support other operators. The first DALI+ certification plan will support DALI+ direct Thread.

We are already working with Thread Group to develop DALI+ with Thread certification, which will be separated from DALI-2 certification. Different operators need their own DALI+ certification plans.

Yes, the bridge interface is defined in the changes and supplementary specifications of part 104 of DALI. Through the bridge, the D4i lamps access the DALI+ network.

Yes, the bridge interface is defined in the changes and supplementary specifications of part 104 of DALI. Through the bridge, the wired DALI-2 device and lamps access the DALI+ network.

When using the 1.5 mm2 (15AWG) cable and the total maximum bus power supply current is 250mA, the recommended maximum distance between any two devices on the DALI bus is 300m. These two lines should be adjacent.
