GB/T 34846-2017 in English

GB/T 34846—2017 Standard Overview

This standard specifies the specifications and interface technical requirements for independent LED modules for road lighting or tunnel lighting, and is applicable to integrated, semi-integrated and non-integrated LED modules.

Main Technical Contents

• LED module specification classification: classified by rated luminous flux, light distribution and rated correlated color temperature.
• Interface technical requirements: including external dimensions and the structure and mating dimensions of electronic connectors.
• Test methods: covering test requirements such as luminous flux, light distribution and electrical parameters.

Specification Comparison

Technical Requirements Analysis

Light Intensity Distribution Test

According to GB/T9468-2008, the light distribution characteristics of the module need to be tested to ensure that it meets the classification listed in Table 1.

Requirements for Electronic Connectors

Electronic connectors must comply with IEC 61984 standards to ensure waterproof performance and plug-in reliability. Appendices E and F specify the dimensional requirements for two-core and three-core connectors in detail.

Implementation suggestions

1. Selection suggestions: Select appropriate LED module specifications according to specific application scenarios to ensure that the light intensity distribution matches the installation requirements.
2. Test verification: Strictly conduct tests in accordance with standards, especially light distribution and electrical parameter tests, to ensure that the product meets the requirements.
3. Quality control: Strictly implement dimensional tolerance requirements (as shown in Table 5) during the production process to ensure module interchangeability.
