With the commercialization of high-brightness LEDs in various colors such as red, yellow, and green, LEDs have gradually replaced traditional incandescent lamps as traffic lights. Today LED traffic lights manufacturer Qixiang will introduce LED traffic lights to you.
Application of LED traffic lights
1. Urban traffic arterial roads and highways: Installing LED traffic lights at intersections and highway sections of urban roads can effectively control the traffic of vehicles and pedestrians and ensure the safety of driving and pedestrians.
2. Roads around schools and hospitals: Roads around schools and hospitals are areas with heavy pedestrian traffic. Installing LED traffic lights can improve pedestrian safety.
3. Airports and ports: As transportation hubs, airports and ports require efficient traffic control systems. LED traffic lights can provide efficient road traffic control for airports and ports.
Development prospect of LED traffic lights
At present, in addition to being applied in high-value accessories such as automotive lighting, lighting fixtures, LCD backlights, and LED street lights, high-power LEDs can also obtain considerable profits. However, with the arrival of the replacement of old-fashioned ordinary traffic lights and immature LED signal lights a few years ago, new high-brightness LED traffic lights have been widely promoted and applied.
LED products used in the traffic field mainly include red, green, and yellow signal lights, digital timing display lights, arrow lights, etc. When the product requires high-intensity ambient light during the day, it should be bright, and the brightness should be lowered at night to avoid glare. The light source of the LED traffic signal command light is composed of multiple LEDs. When designing the light source, multiple focal points must be considered, and there are certain requirements for the installation of the LEDs. If the installation is inconsistent, the uniformity of the light effect of the light-emitting surface will be affected.
There are also certain differences between LED traffic signal lights and other signal lights (such as car headlights, etc.) in light distribution, although there are also requirements for light intensity distribution. The requirements on the light cut-off line of automobile headlights are more stringent. The design of automobile headlights only needs to allocate enough light to the corresponding place, regardless of where the light is emitted. The designer can design the light distribution area of the lens in sub-regions and small blocks, but traffic lights also need to take into account the entire The uniformity of the light effect of the light-emitting surface must satisfy that when the signal light-emitting surface is observed from any working area used by the signal light, the pattern of the signal must be clear and the visual effect must be uniform.
