How to Choose the Right LED Traffic Signal Light - Complete Procurement Guide

Introduction

Choosing the right LED traffic signal light is crucial for urban traffic safety. Whether you're building new roads, upgrading traffic signal systems, or procuring temporary traffic control equipment, multiple factors need careful consideration. This comprehensive guide will help you understand the key points for selecting LED traffic signal lights.

1. Determine Basic Parameters

1.1 Size Selection

LED traffic signal light size directly affects visibility distance and application scenarios:

Expert Recommendation: For urban main roads, use 300mm or larger specifications to ensure sufficient driver reaction time.

1.2 Aspect Selection

2. Brightness & Visibility

2.1 Luminance Requirements

According to international standards, LED traffic signal lights need to meet:

• Daytime: ≥ 400 cd/m²
• Nighttime: ≥ 100 cd/m²
• Foggy conditions: Higher brightness required

2.2 Viewing Angle

Quality LED signal lights should have:

• Horizontal: ±30°
• Vertical: ±10°

Note: Ensure products comply with GB 14887-2011 or EN 12368 standards.

3. Power Type Selection

3.1 Mains Power Supply
