Lighting Accessories For Outdoor Led Street Light

Outdoor led street light has the characteristics of energy saving and environmental protection, high luminous efficiency, long service life, good lighting effect and so on.At present,LED street lamp has replaced traditional high-pressure sodium lamp on a large scale.Do you know that what are the accessories for outdoor LED street light?And what are the functions respectively of each lighting accessories?This blog post will get you into the world of led street light parts!

Typically, a set of complete LED lighting fixture mainly consist of these important parts of LED light source(LED lamp bead), drive power supply, controller, radiator and housing etc.Keep reading!This article will told the related knowledge of each lighting accessories for outdoor led street light one by one.After reading & study,you know how to better choose suitable outdoor led street lamps for your lighting projects.

LED light source

At present, the common light source has DC energy-saving lamp, high frequency electroless lamp, low pressure sodium lamp and LED light source in the lighting market.LED light source (LED refers to Light Emitting Diode) is a light-emitting diode light source. This kind of light source has the advantages of small volume, long life, high efficiency, can be used for up to 100,000 hours.LED light source application in the field of lighting has become the mainstream.

As a new generation of light source, compared with incandescent lamp, high pressure sodium lamp and other traditional heat radiation and gas discharge light source,LED light source has a great difference, LED light source in road lighting has the following advantages:

1. High luminous efficiency

After decades of technical improvement of LED, its luminous efficiency has been greatly improved. The luminous efficiency of incandescent lamp and halogen tungsten is 12-24 lumens/w, fluorescent lamp is 50-70 lumens/w, sodium lamp is 90-140 lumens/w, most of the electricity consumption become heat loss.After improvement,LED light efficiency will reach 50 ~ 200 lumens/watt, and its light monochromaticity is good, spectrum is narrow, can directly emit colored visible light without filtering.

2. Less power consumption

LED single tube power is 0.03 to 0.06 watts, dc drive, single tube drive voltage is 1.S5 to 3.5 volts, current is 15 to18 ma, fast reaction speed, can be operated at high frequency.Under the same condition of the same luminous effect,the power consumption of LED lamps is one ten-thousandth of incandescent bulb,and the half of fluorescent lamp.

3. Long service life

The service life of LED lamps can reach 5 ~ 10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of changing lamps frequently.

4. Strong safety and reliability

LED lamps has the characteristics of low calorific value, no heat radiation, cold light source, safe to touch.

5.Environmentally friendly

LED is full solid luminescent body, shock resistance, impact resistance is not easy to break, waste can be recycled, no pollution.

Drive power supply

In layman's terms, the LED drive power supply is a converter.Its function is to convert our common mains supply or other power sources into voltage and current suitable for LED use.Through its conversion, the LED can work properly and emit light.For example,if we want to unscrew a nut, we must use the same type of wrench.

LED driving power supply is not only an indispensable parts of LED lighting fixtures, but also the main factor affecting the stability of LED lamps.So how to choose suitable drive power supply for led lamp?This is a question worth thinking about!

Led controller

Generally speaking of "LED", the lamps used in public lighting area will come into your mind.And who knows how to control these lights?At this time we need to use led controller.The so called led controller, is to process and control a number of switches in the led lamp circuit through the chip.LED controller is widely used in municipal roads, highways, Bridges, tunnels, gardens, docks, sightseeing lights, sports squares, amusement places, advertising light boxes and other public lighting environment.

Radiator

The role of radiator for outdoor led street light is to absorb the heat from the substrate or chip, and then disperse to the outside environment, so as to ensure the normal temperature of the LED chip.Most radiators are carefully designed for using in both natural and forced convection conditions.

Referring to the radiator, it is necessary to talk about the problem and solutions of heat dissipation of LED street lamps.In daily life, many people only know LED lamps can illuminate our road, but do not know the road lamp cap also has a heat dissipation system.Just as people need a sweat system on a hot summer day, they need to turn on a fan to cool down.LED street lamps work outdoors for a long time, and the temperature difference outdoors is very large, so it is necessary to have a good heat dissipation system.Especially for high-power LED street lamps, if the heat dissipation is not solved well, the light decay will be very large, and the lifespan can not be guaranteed.

LED lamp housing

The LED housing not only protects the LED from external elements, but also dissipates heat and keeps the LED temperature under control.

The above is the knowledge about the main lighting accessories for LED street lamps shared by editor.In all,each lighting accessories of outdoor led street light  has its own role and is indispensable.So we need to regularly check and maintain led lamp accessories, so as to ensure the good work performance and service life of it.
