Street lights help keep streets safe by marking public roads and sidewalks in many communities and prevent accidents among drivers and pedestrians.Old street lights use traditional bulbs while more modern lights use energyEnergy-saving LED technology.In both cases, street lights need to be durable enough to withstand these elements while continuing to provide lighting.One component common to all types of street lights is the post, which rises from the bottom of the ground and supports the lighting elements above.The street lamp column contains wires that connect the lights directly to the grid.Some positions also include service doors that enter the street lamp control unit and perform repairs or adjustments from the ground.Street lamp positions need to be able to withstand the test of ice, wind and rain.Rust-The resistant metal or paint protective layer can help keep the pillars from the damage of the elements, and the metal is by far the most common material with its strength and rigidity.Some street lamp pillars, such as street lamp pillars in historic blocks, may be decorative, while others are simple gray pillars.Street light bulbs come in a wide variety of styles and sizes.Most traditional street lamps use halogen lamps, which are similar in function and appearance to household incandescent lamps.These bulbs are made up of vacuum tubes and inert gases (such as halogen lamps) with filaments inside, which cause the burning part of the filaments to recall on the filaments and extend the life of the bulbs.Metal halogen lamps use similar techniques, but use less energy and produce more light.A fluorescent street lamp bulb is a fluorescent tube that contains a gas that reacts with the current to produce lighting.Compared with other bulbs, fluorescent street lamps use less energy and emit green light, while halogen lamps emit warm orange light.Finally, light-LEDs are the most effective street light bulb type.LEDs are a semiconductor that can produce a strong lighting effect, much longer than the duration of the bulb.LED street lamps include heat exchangers used to adjust the temperature.These devices regulate the heat generated when the current is supplied to the LED.The heat exchanger uses air channels on a series of fins to keep the lighting elements cool, and make sure the LED is able to produce even light without a darker area or a "hot spot" otherwise this can happen.LED and traditional street lamps adopt curved lenses usually made of heavy-duty lensesGlass or more common plastic.The street lamp lens can amplify the effect of the internal light.For maximum efficiency, they also directed the light down the street.Finally, the street lamp lens protects the delicate lighting elements inside.Blurry, scratched or broken lenses are easier and more costlyEffective than replacing the entire lighting element.
