There are problems in the lighting of advertising column
        Advertising is the use of post is basically a high pressure sodium lamp, high pressure sodium lamp because of its high brightness, long has been advertising column lighting the main lighting lamps and lanterns, however, its high current, high power, high energy consumption to energy and environmental protection, and caused a huge waste. And column ad is basically after nightfall uninterrupted lighting, for electric energy consumption and the life of lamps and lanterns is a great test. Very low color high-pressure sodium lamp color index is less than 30, not good effect in advertising such occasions.

Therefore, the advertising column lighting needs to have a high energy saving, high brightness, high color rendering, long life characteristics.

LED cast light lamps and high pressure sodium contrast

1, energy conservation: the white LED luminous efficiency is about 90 Im/W, actual lighting effects tested than column ad is currently used in high-pressure sodium lamp integrated energy-saving 50% ~ 60% (by the tariff cut in half). With the rapid development of LED technology, the LED projection lamp has a huge potential in energy saving.

2, long life and low maintenance cost: high power LED light source can be normal with 4 ~ 5 years without replacement, and traditional high-pressure sodium lamp average a year and a half to replace a, greatly reduce the maintenance cost, saves the manpower and resources. The high cost, high risk and long life of LED cast light lamp can greatly reduce the cost of replacement of the artificial cost and accident risk.

3, the color of good: LED cast light color rendering index greater than 75, especially on the occasion of the advertising, advertising looks brighter, feeling more comfortable; and high pressure sodium lamp color rendering index of less than 30, narrow spectrum, poor color, advertising seems to feel faint.

4, green environmental protection: on the environment without any pollution, and does not produce electromagnetic interference (high pressure sodium lamp contains mercury and xenon elements, the electronic ballast will produce electromagnetic interference), non polluting to the power grid, power factor is greater than or equal to 0.9, EMI in line with the global index.

5, protection performance: LED cast light lamp uses the semiconductor chip to light, not the traditional tube fragmentation problem, strong earthquake resistance, the use of high reliability of advanced packaging technology, fully protect the LED lamp life.

6, high safety factor: the characteristics of DC low voltage work compared to the traditional lamps more safe and reliable, LED cast light on the required voltage, current is small, less heat, no safety hazard.

Application effect of LED lamps
      According to the needs of users, the an advertising column replacement for LED cast light, originally is the use of 18 high-pressure sodium lamp lighting, in order to ensure the illumination brightness under the premise we used 18 lamp popularity led light cast light lamps to replace:

 Note: work 12 hours a day, electricity is 1 yuan / degree

       Through the above data comparison, we can find replace led cast light lamps a year of electricity than the use of high pressure sodium lamp saves $23328. This is no additional maintenance costs often HPS and green environmental advantages.

Advertising column special universal light LED projection lamp

1, thermal design by superconducting aluminum radiator, using advanced phase-change heat transfer ways to enhance the heat dissipation capability, with temperature integration;

2, power supply design, anti surge absorption circuit, load protection, open circuit protection, EMC circuit design, power efficiency of more than 90%, power factor of up to 95;

3, LED light source: LED lamp with integrated light source of imports, high light efficiency, high color rendering index, longer life; optical design using special optical design, uniform light, no glare; energy saving and environmental protection without mercury and other heavy metals and UV.

4, the product has passed UL, TUV, CE, SAA, RoHS certification.
