1、 Product Overview

The light source adopts imported ultra-high brightness LED. The lamp housing is made of disposable aluminum die-casting or engineering plastic injection molding. The diameter of the luminous surface of the lamp panel is 300mm and 400mm. The lamp post is processed and formed from high-quality steel plate, and the surface is sprayed with plastic after light heat zinc treatment. All technical parameters comply with the GB14887-2011 standard for road traffic signals of the People's Republic of China.

2、 Product advantages

1. The light source adopts ultra-high brightness LED light-emitting tubes, composed of two sets of LED units, equipped with a balance circuit and specially designed optical components, which emit light uniformly, with clear and beautiful images.

2. The control circuit design is reasonable and reliable, and the pedestrian pattern display of the countdown pedestrian light is synchronized with the numerical value displayed during the countdown.

3. The outer shell of the lamp body is made of PVC plastic or aluminum, which is lightweight and solid, reliable, stable, and waterproof. It is beautiful and durable, with a beautiful appearance, bright brightness, and long service life. All indicators meet the GB14887-2011 standard. High brightness LED light source, low heat, environmentally friendly and energy-saving. The unique exterior design allows the lamp body to be combined with any number of units.

Features:

1. The unique light source of LED traffic lights: using a bright and luminous large chip, with a 5mm round LED.

2. Adding a "balanced current" resistor to the LED traffic light unit's luminous circuit can reduce the difference in branch current by 30%,

Increase the average time between failures of light-emitting tubes and increase their service life.

3. Overvoltage and overcurrent protection: In case of special circumstances, such as output short circuit or input voltage>270V, the fuse

Fusing or breakdown of varistors to fuse and protect the luminous system.

Expanded the shading surface, blocking the impact of diffuse backscattered light, specular reflection light, ambient light reflection, and transmitted light from behind on vision;

4. The traffic light adopts a PC shell, which has the characteristics of light weight, good insulation, and corrosion resistance.

5. High IP protection level: IP65, effectively extending product life without being affected by dust and rainwater immersion.
