LED 가로등 시리즈

LED road light are installed on the side of the road for lighting lights.

Road lighting is closely related to people’s production and life, with the acceleration of urbanization, LED street lamps with directional light, low power consumption, good driving characteristics, fast response time, high seismic capacity, long service life, green and environmental protection and other advantages gradually into the people’s field of vision, become the world’s most alternative to the advantages of the traditional light source of a new generation of energy-saving light source, therefore, LED street lamps will become the best choice for energy-saving transformation of road lighting!

Characterization of Street Lighting

LED street light and conventional street light is different, LED light source using low-voltage DC power supply, by GAN-based power blue LED and yellow synthesis of high-efficiency white light, with high efficiency, safety, energy saving, environmental protection, long life, fast response speed, color rendering index and other unique advantages, can be widely used in roads.

The outer cover is available for production, high temperature resistance up to 135 degrees, low temperature resistance up to -45 degrees.

장점

• LED Street Light own characteristics – unidirectional light, no light diffusion, to ensure light efficiency;
• 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;
• LED has reached 110-130lm / 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, therefore, the overall light effect of LED street lamps than high-pressure sodium lamps; (this overall light effect is theoretical, in fact, more than 250W high-pressure sodium lamps are higher than the LED lamp light effect);
• LED street light color rendering than high-pressure sodium lamps, high-pressure sodium lamps color rendering index is only 23 or so, while the LED street light color rendering index reaches 75 or more, from the visual psychological point of view, to achieve the same brightness, LED street light illuminance can be reduced by 20% or more than high-pressure sodium lamps, on average;
• 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;
• LED street lights have automatic control of energy-saving devices, can be realized to meet the lighting requirements at different times of the year under the circumstances of the maximum possible reduction in power, saving electricity. Can realize computer dimming, time period control, light control, temperature control, automatic inspection and other humanized functions.
• long life: can be used more than 50,000 hours, provide three years of quality assurance. The disadvantage is that the life of the power supply is not guaranteed.
• high luminous efficacy: the use of ≥ 100LM above the chip, relative to the traditional high-pressure sodium lamp can save energy more than 75%;
• 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.
• excellent thermal control: summer temperature control below 45 degrees, and the use of passive cooling, summer cooling protection is not enough;
• reliable quality: circuit power supply all high-quality components, each LED has a separate over current protection, no need to worry about damage;
• light color uniformity: no lenses, not to improve the brightness at the expense of uniform light color, thus ensuring that no aperture light color uniformity;
• LED does not contain harmful metal mercury, will not cause harm to the environment at the end of life.

Composition of LED street light

LED light source (1W-200W), die-casting aluminum street light shell, LED power supply, electric wire, light pole, light arm, foundation embedded parts.

Low maintenance cost

Relative to traditional street lamps, LED street lamps maintenance costs are extremely low and easy to maintenance and fix.

LED street light application places

LED street light is mainly used in main roads, secondary roads, branch roads, factories, schools, gardens, city squares, courtyards and other road lighting.

Installation height of street lights

Choose a good height, it determines the lighting vision of the street lights

1. the lamps and lanterns installation height, the same street lamps and lanterns installation height must be the same (luminous center to the ground height),
   5-6 meters of ordinary streets.
   Long arm lamps and chandeliers 6.5-7.5 meters.
   Fast lane arc lamps not less than 8 meters
   Slow lane arc lamp not less than 6.5 meters
2. Special lamp type is installed according to the design requirements, the height of the lamp is roughly equivalent to the width of the road to be illuminated.
