LED 가로등

Street lights, also called road lights, refers to the road to provide lighting function of the lamps and lanterns, refers to the traffic lighting within the scope of road lighting lamps and lanterns, street lamps are widely used in a variety of places that need lighting.

Street light mainly consists of lamps, wires, light sources, poles, arms, flanges, foundation pre-buried parts to form a whole.

Street light types:

1、According to the height of street lamps: high pole lamps, medium pole lamps, road lamps, garden lamps, lawn lamps, buried lamps;

2, according to the street lamp pole material: hot dip galvanised iron street lamp, hot dip galvanised steel street lamp and stainless steel street lamp;

3, according to the street lamp light source: sodium street lamps, LED street lamps, energy-saving street lamps, new Somin xenon street lamps.

4, according to modelling: Chinese lights, antique lights, landscape lights, single-arm street lights, double-arm street lights.

5、According to the power supply mode: utility street light, solar street light, wind and solar hybrid street light.

LED street light refers to the street light made of LED light source, which has the unique advantages of high efficiency, safety, energy saving, environmental protection, long life, fast response speed, high colour rendering index.

LED street light advantages:

1, its own characteristics – unidirectional light, no light diffusion, to ensure light efficiency.

2, LED street light has a unique secondary optical design, the LED street light to the required lighting area, further improving the light efficiency to achieve energy saving.

3, LED has reached 110-180lm / W, and there is a lot of room for development, the theoretical value of 360lm / W. The luminous efficiency of high-pressure sodium lamps is increased with the increase in power only increased, therefore, the overall light effect of LED street lamps than high-pressure sodium lamps; (this overall luminous efficacy is a theoretical, in fact, more than 250W high-pressure sodium lamps are higher than the LED lamps).

4, LED street lamps light colour rendering than high pressure sodium lamps, high pressure sodium lamps colour rendering index is only about 23, and LED street lamps colour rendering index reaches more than 75, from the visual psychological point of view, to achieve the same brightness, LED street lamps illumination can be reduced by an average of 20% or more than high pressure sodium lamps.

5, light decay is small, a year of light decay less than 3%, the use of 10 years still meet the road requirements, while the high pressure sodium light decay, a year or so has declined by more than 30%, therefore, the LED street lamp in the use of power design can be lower than the high pressure sodium lamp.

6, LED street lights have automatic control of energy-saving devices, can be achieved to meet the lighting requirements at different times of the case of the maximum possible reduction in power, saving electricity. Can achieve computer dimming, time period control, light control, temperature control, automatic inspection and other humane functions.

7, long life: can be used more than 50,000 hours, to provide three years of quality assurance. The shortcoming is that the life of the power supply is not guaranteed.

8, high luminous efficacy: the use of ≥ 100LM chip, compared with the traditional high-pressure sodium lamp can save energy more than 75%.

9, easy to install: no need to add buried cable without rectifier, etc., will be installed directly on the pole connected or the light source nested in the original lamp shell.

10, excellent thermal control: summer temperature control below 45 degrees, and the use of passive heat dissipation, summer cooling protection is not enough.

11, reliable quality: circuit power supply all high-quality components, each LED has a separate overcurrent protection, no need to worry about damage.

12, light colour uniformity: no lens, not to improve the brightness at the expense of uniform light colour, thus ensuring no aperture light colour uniformity.

13, LED does not contain harmful metal mercury, in the end of life will not cause harm to the environment.

14, low maintenance costs: relative to traditional street lamps, LED street lamps maintenance costs are extremely low, after comparison, less than 6 years to recover all investment costs.
