Difference Between Active Light-emitting Sign And Passive Light-emitting Sign

The differences between active and passive light-emitting signs are as follows:

Active luminous signboard

First, let's talk about the active light-emitting signs. It is inevitable that we will encounter some solutions in the process of driving. For example, we can't see the words on the road signs because of bad weather. The active light-emitting traffic signs are also called LED light-emitting traffic signs. They can be used by solar energy, wind energy, or connected to the city power through voltage transformation. It refers to the traffic signs such as warning signs, indication signs, direction signs, prohibition signs, auxiliary signs and construction protection in the form of active lighting specified in the national standard gb5768-2009 road traffic signs and markings, as well as the self-developed traffic sign products with LED as the light source.

From this picture, you can know that the words in the road guide signs can be clearly displayed at night, and you won't be unable to see them clearly because of the darkness.

Principle of active luminous signboard

With strong light penetration and long visual distance, it can meet various adverse weather conditions and effectively reduce traffic accidents; With its own light source to take care of all traffic subjects

Passive luminous plate

At present, the traditional light-emitting signs rely on reflective film to achieve reflective effect. High intensity lamps are required to illuminate to achieve the luminous effect.
