||Our Street Lighting Team is responsible for the maintenance of street lighting and manage a variety of functions associated with the community associations in Delaware County.
Our Team also provides a consultancy and design service to private developers Councils and other community organizations. To report a faulty Street Light - Faulty lighting is repaired during the daytime, when all of the lights should be off.
If you are reporting a faulty street light, please help us to locate its position by providing the complete reference, painted in white, on the column. We'll diagnose problems of street lights with the electricity power supply on in order to
detect the location of failures. Photo operated circuits must be jumped out to see if the lighting fault you are concerned about has already been reported to the utility company.|
|Most parking lot and area lighting commonly uses HID type lighting fixture which stands for high-intensity discharge lamps, HPS high pressure sodium
lamps of Metal Halide M.H. Such lamps provide the greatest amount of photo optic illumination for the least consumption of electricity. However when lighting calculations are used, it can been seen how inappropriate HPS lamps are for night lighting.
White light sources have been shown to double driver peripheral vision and increase driver brake reaction time at least 25%. When S/P light calculations are used, HPS lamp performance needs to be reduced by a minimum value of 75%.|
New street lighting technologies, such as Light Emitting Diode (LED) and Induction emit a white light that provides high levels of scotopic lumens allowing street lights with lower wattages and lower photopic lumens to replace existing street lights.
However, there have been no formal specifications written around Photopic/Scotopic adjustments for different types of light sources, causing many municipalities and street departments to hold back on implementation of these new technologies until the standards are updated.
Incandescent lamps were primarily used for street lighting until the advent of high-intensity discharge lamps. They were often operated in high-voltage series circuits. Series circuits were popular since the higher
voltage in these circuits produced more light per watt consumed. Furthermore, before the invention of photoelectric controls, a single switch or clock could control all the lights in an entire district.
To avoid having the entire system go dark if a single lamp burned out, each street lamp was equipped with a device that ensured that the circuit would remain intact. Early series street lights were equipped with isolation
transformers that would allow current to pass across the transformer whether the bulb worked or not. Later the film cutout was invented. The film cutout was a small disk of insulating film that separated two contacts connected to the two wires leading to the lamp.
If the lamp failed (an open circuit), the current through the string became zero, causing the voltage of the circuit (thousands of volts) to be imposed across the insulating film, penetrating it. In this way, the failed lamp was bypassed and power restored to the rest of the district.
The street light circuit contained an automatic voltage regulator, preventing the current from increasing as lamps burned out, preserving the life of the remaining lamps. When the failed lamp was replaced, a new piece of film was installed, once again separating the contacts in the cutout.
This system was recognizable by the large porcelain insulator separating the lamp and reflector from the mounting arm. This was necessary because the two contacts in the lamp's base may have operated at several thousand volts above ground/earth.
