Intelligent LED street lamp

Intelligent LED street lamp with a fourth-generation light sources (LEDs) as light-emitting main,

with a high luminous efficiency, less power consumption, long life, safe and reliable, light a light

rate, environmentally friendly features. Used in the field of urban trunk road (Main road) city

roads (Street) Industrial Park roads, urban and rural roads.

The principle of intelligent LED lights and a variety of applications of intelligent LED street lamps

with induction of ICT with the demand for road lighting, and lead to many additi onal applications,

and more to enhance the efficiency of lighting and security. The following profile has been the

development of induction types of LED street.

(A) real-time fault notification

Failure to repair the existing road lighting, for example, manual inspection approach is often

limited by human factors, and easy to produce delays in repair, causing the public inconvenience.

LED Lighting Energy Smart of the Taiwan Institute for Information Industry will develop a full

range of solutions, the use of Power Line Communication (PLC) transmission of electrical

equipment in use, in the event of failure can be immediately detected and a message prompts,

effectively shortening the repair time and reduce the traditional human maintenance costs.

(B) illumination flexibility to adjust

Intelligent LED systems can also make use of the brightness sensor, microwave vehicles and

sensors to detect the ambient light intensity and the people and vehicles activities at any time

change state, via the ZigBee wireless sensor networks, Power Line Communication (PLC),

transmission of information, analysis, automatic control lights lumens. Automatically by the

system during the unmanned vehicle activities, the LED lighting be adjusted to meet the

environmental safety of low lumen illumination, on the contrary, intensive period of activity of

people and vehicles, while the high lumen LED lighting, improve the clarity of sight of drivers to

ensure road safety sex.

Toulouse, southwestern France (Toulouse) pilot induction street lights in the local public roads

and on college campuses, the temperature can detect pedestrians and vehicles, automatically

double the street lamp brightness, when the people and vehicles to leave after 10 seconds, it

automatically back into the dim lighting state. Toulouse city government estimates, the induction

street lights, if the pilot is successful, will be extended to the city, to save at least half of the

street lamp power consumption; French environmental groups advocating to set up the induction

street lights, only power, but also to protect the ecological environment.

Illumination adjustment type LED lamp key is the logic of the sensor and illumination adjustment.

Sensor portion of the infrared sensor sensing temperature, sensing the temperature of the object

for more than 35 ℃, as a person or vehicle, according to which "circular controller turning up

the brightness of the street lamp, another way is to use image recognition technology.

Taiwan's Industrial Technology Research Institute Energy and Environment Research pointed out

that the road for vehicles to install induction street lights and home in front of sensor lights,

because when the moment when people and vehicles near the light, this will cause too large

contrasts, and instantly The lights will light up the formation of "disability glare", visual impact, it

may cause a traffic accident. Over the traffic during peak hours, as long as the street lamps to

maintain 1/3 or 1/2 of the illumination after midnight, almost no car, the illumination can also be

transferred to a lower power efficiency is quite high.

Even through the sensor in the middle of the night have the vehicle passes through the vehicle

after the location of the next lamp or the next row of street lamps to redouble electric light, after

a period of time, the sensors undetectable vehicle and automatically restore the pre-set

brightness or completely extinguished.

Dimmable lamps is a prerequisite for the induction street lights, the most common mercury lamp

dimming, sodium lamp, although dimmable, but the adjustment speed is slow, is not ideal, you

can transform the brightness and colors of LED lights is the induction street lights choice.

(C) the color temperature flexibility to adjust

The car usually at night, car headlights is white or yellow light, with $ fog lamps vehicles

encountered fog, you can rely on the fog lights to improve visibility. Intelligent street lighting

through the sensor can also automatically detect fog, light, and emergencies, the elastic to adjust

the color of the highway lights.
