Introduction

As an important part of lamp accessories, interchangeability and safety are fundamental requirements for ensuring safe production of lamp holders. GB/T 1406 "Lamp Holders" the "Type and Size of Lamp Heads" aims to standardize the type and size of lamp heads, and proposes to consist of five parts.

---Part 1: Screw-in Lamp Holders. The purpose is to specify the types, basic dimensions, and inspection methods for screw-in lamp holders.

---Part 2: Plug-in Lamp Holders. The purpose is to specify the types, basic dimensions, and inspection methods for plug-in lamp holders.

---Part 3: Prefocused Lamp Holders. The purpose is to specify the types, basic dimensions, and inspection methods for prefocused lamp holders.

---Part 4: Miscellaneous Lamp Holders. The purpose is to specify the types, basic dimensions, and inspection methods for miscellaneous lamp holders.

---Part 5: Bayonet Lamp Holders. The purpose is to specify the types, basic dimensions, and inspection methods for bayonet lamp holders.

GB/T 1406.2-2008 has been published for over ten years, and the types and sizes of lamp holders specified in it are no longer compatible with the current interchangeability and safety of lamp holders.

Improving product safety and quality, standardizing the market, and enhancing the competitiveness of Chinese products are all of great importance.
