Street & Roadway Lights
LED Street Light Supplier
A street light, light pole, lamppost, street lamp, light standard or lamp standard is a raised source of light on the edge of a road or path. Similar lights may be found on a railway platform. When urban electric power distribution became ubiquitous in developed countries in the 20th century, lights for urban streets followed, or sometimes led.
Many lamps have light-sensitive photocells that activate the lamp automatically when needed, at times when there is little to no ambient light, such as at dusk, dawn, or at the onset of dark weather conditions. This function in older lighting systems could be performed with the aid of a solar dial. Many street light systems are being connected underground instead of wiring from one utility post to another. Street lights are an important source of public security lighting intended to reduce crime. (Wikipedia)

Enhancing the appearance and urban design of the area especially in dark. Arrangement of lights in a commercial street describing the character of the street
Implementing Street Lights: Important Factors to remember before Installing
Lighting arrangements may be used to identify the functions of different roads and create an urban design effect. For example, two light poles at the entrance to a road can be used to create a gateway effect to any area. Sizing of trees and shrubs when mature and their location in any layout plan must be considered in relation to location of street light poles.
Adequate lighting should be provided in all parts of the area/layout to enhance safety and security for drivers, cyclists and pedestrians as well. Lighting is also necessary to illuminate bottle necks, bends and traffic calming features, to enable road users to see the potential obstacles and each other in the night to reduce the fear of crime.
Street lighting must be planned as an integral part of the initial layout of access and shared surface roads, driveways, walkways and in conjunction with the location and anticipated growth of trees/shrubs. The uniqueness of lighting provided should confirm that shadows are avoided in places where pedestrians/cyclists would otherwise be vulnerable.
6 Types of Street Lights
Low Pressure Sodium (LPS)
The low pressure sodium (LPS) lamp works similarly to the HPS light. Instead of producing white light (all the colors of the rainbow), LPS lamps produce almost exclusively yellow light. While this light is fairly efficient, it takes several minutes for the bulb to turn on. The light is very yellow-orange. This yellow light makes objects it is illuminating look a different color or gray.
LED Street Lamps
LED technologies have developed rapidly in recent years and these bulbs are now being integrated into outdoor lighting solutions. While the energy savings are significant, LEDs produce a lot of blue light, too much of which can have negative effects on human health and wildlife.
High Pressure Sodium (HPS) Street Lights
The high pressure sodium lamp (HPS) is the most commonly used street light in many countries throughout the world. It produces bright light by electricity via mixture of gases, which produces light. The lamp itself is much preferable because it requires very little/less maintenance. These lamps are fairly efficient. They take few minutes to turn on completely and produce a yellow-orange kind of glow.
Metal Halide Street Lights
Metal halide lamps/bulbs are mainly used in streetlights, parking lot lights, and stadium lights. They are very bright in color and contribute to a lot of light pollution. They are fairly efficient. They produce very white light and have good color performance/rendering, meaning that objects under these lights look their true color.’
Phosphor-Converted Amber (PCA) LED Street Lamps
PCALEDs have only been on the market for the past few years. They use very little energy and have good color rendition, but are still rather expensive. Some cities have already installed these lights on their streets.
Narrow-Band Amber (NBA) LED Street Lamps
Narrow-band amber (NBA) LED street lights are a brand new technology. Rather than emitting all the colors of the rainbow and a lot of blue light, they emit mostly in the yellow. They still have good color rendition, meaning that they do not make things look grey like LPS lamps do. Because this technology is so new, these bulbs are not widely available and as such, are still expensive. They are very efficient.
