A street light, street lamp, lamppost, pole, post, standard or light fixture are usually a metallic erected structure on the side of a roadway or pathway. They are designed to catch and redirect lighting from passing drivers so that they may move safely and appropriately. Other types of street lights include vehicular lights, which are intended for use in combination with another vehicle type such as a car or a bicycle, and street lights are often used in combination with street lamps.
There are many uses for temporary changes of street lights, some of which include security and holiday lighting. Security and holiday lighting is used to alert drivers about approaching vehicles, to mark off where no parking is allowed, and to temporarily change the visibility of the road. In addition, temporary changes of lighting can be used for aesthetic effect in a particular area.
Sidewalks and public walkways are generally dark at all times, making it difficult to locate nearby street lights, let alone holiday lighting. Sidewalks are illuminated using low-powered, low-hanging lamps known as headlamps. Headlamps have two lenses, the first with a high-power HPS, or high-pressure sodium, bulb to provide bright illumination. The second lens has a lower power rating; however, is not high-hanging and does not produce harsh shadows. Sidewalk lights are also commonly used along sidewalks to provide illumination, especially at night.
High-pressure sodium lights are typically used for decorative purposes on the side of a building, on landscaping or near a water body. Floodlights aimed at a specific object for general illumination is also common, as are lights designed to provide different levels of task lighting. These can be classified according to the number of bulbs, the type of bulb and its brightness, as well as its use.
Another common use for street lighting is to mark entrances or exit routes into a building. This serves practical and functional purposes, as well as improving safety for both pedestrians and building occupants. The various types of signals include traditional green and red lights, as well as LED and Night Glow signals. LED, or light emitting diode, is the more recent technology, replacing the traditional incandescent bulb. These new types of signal fixtures offer brighter light and longer lasting bulbs, which make them ideal for both commercial and residential applications.
Street lights can help reduce pedestrian fatalities and accidents, especially during holidays when many people are out of town. Unfortunately, too many pedestrian accidents occur during the busy summer months. This tragic occurrence is often due to inadequate or improper pedestrian safety measures, such as lack of traffic signals or improperly installed pedestrian lighting. Improving on-site lighting is an easy and inexpensive way to prevent pedestrian accidents, which can be a costly nuisance and can cause serious damage to personal property.
