Zhaga Alliance revised LED street light specification to resolve COB restrictions

January 23, 2023

Recently, the Zhaga Alliance is actively working on the existing specifications for LED street lights. Due to the smaller size of the LED street light module in the Book 4 specification of the Zhaga Alliance at the end of March 2012, the LED street light module has a small size, which makes it impossible to efficiently import COB (Chip On Board) process technology that can achieve high lumens. The cost of streetlight products, as well as the life and performance of the products, has been revised by the Zhaga Alliance.

Everlight Electronics said that the size of the LED streetlights defined by the Zhaga Alliance is small. For street lamps that require high lumens, the brightness will be insufficient, and during the development process, the industry will not be able to adopt large-area LED arrays and high lumens. The COB process technology, therefore, LED street lights will not meet the market requirements in terms of life and brightness.

At the same time, Yiguang believes that COB process technology has high lumens, good heat dissipation, and better efficiency and cost performance when combining multiple LED chips. The electrical combination, substrate form, voltage, LED chip size and arrangement are easy to adjust. Customized LED lighting design. However, in the application of small-area LED arrays, the advantages of COB technology will not be able to play, so the Zhaga Alliance Book 4 street light specification limits the development of LED street lights, and even can not attract the industry to develop products according to standards.

In addition, in addition to the revision of Book 4, the future Zhaga Alliance will also release specifications for LED outdoor lights and tunnel lights, and strive to standardize the specifications of various LED application terminals. In May of this year, the Zhaga Alliance began the Book 2 specification certification, which is the integration of electronic controller (ECG) LED downlight certification, and announced two certification laboratories.
