57w Economical Residential Street Lights

Q: 1. How can proper lighting help make residential development safer?

Improving street lighting is widely regarded as an effective means of crime prevention, second only to increasing the police force. In fact, residents of crime-ridden neighborhoods often demand improved lighting, and recent studies have generally confirmed their expectation that improved lighting does reduce crime.

Q: 3. What circuit is used for street lights?

Most of the early street lights operated on high-voltage "series" circuits. Long before the invention of personal photoelectric control, this type of circuit allowed a large number of lights in an area to be controlled by a single switch or clock. Current will pass through each lamp in series.

In fact, residents of crime-ridden neighborhoods often demand improved lighting, and recent studies have generally confirmed their expectation that improved lighting does reduce crime.

2. What is the principle of street lights?

The diffuse nature of the street or pavement causes a certain part of the incident light to be reflected in the direction of the observer, which makes the road surface appear brighter to the observer. In the case of the diffusion principle, the lamp is filled with a suitable reflector.

3. What circuit is used for street lights?

Most of the early street lights operated on high-voltage "series" circuits. Long before the invention of personal photoelectric control, this type of circuit allowed a large number of lights in an area to be controlled by a single switch or clock. Current will pass through each lamp in series.
