Trademark Usage

The Trademarks listed on this page (logos and wordmarks) are reserved for use by DALI Alliance (DiiA) members ONLY.
DiiA membership allows use of these Trademarks in accordance with the DiiA Trademark Guidelines (available to members only).

OEM and ODM products

Products manufactured by a DiiA member, but bearing the name of another company, shall not bear the DALI Trademarks (listed on this page) unless the company name shown on the product is that of a DiiA member.

The DiiA member’s name and manufacturer’s part number, as shown on the product, shall be used for registration or certification and shall be listed in the Product Database.

All Trademark rules described in the Trademark Guidelines also apply to rebranded products.


Member company X makes a product and it is certified and visible on the DiiA website with the brand “X”. This company then makes it available to another member company, “Y”, with the product bearing the branding of company “Y”.

In regards to Trademark use, these are two different products. To allow Trademark use, company “Y” needs to submit the product for certification with this new brand. Trademark use is not permitted until this product is visible to the public in the product database, with the brand “Y”.

The Product Submission Guide explains GTIN and testing requirements for ODM/OEM products.
