To alleviate traffic congestion phenomenon

All the year round in the underground subway control lamp has a high requirement. Demand not only micro grid tie inverter saving, high brightness, long life. Must also ensure uninterrupted lighting.

At present, the commonly used incandescent lamp, fluorescent lamp, high pressure sodium lamp, etc are made with ac power supply.

Optimum design of ac power grid also inevitably appear blackouts.

In order to ensure uninterrupted lighting underground.

Usually must be installed by the rectifier, inverter and battery components of emergency lighting power supply.

When normal power grid, the alternating current into direct current to the battery charging after rectifier; When interruption of power grid power supply.

The battery through the inverter the dc into ac, to power a lighting lamps and lanterns.

The uninterrupted lighting system cost is very high, at the same time, after many transformations. Power consumption is bigger also.

In recent years, the other dc power supply of semiconductor lighting (LED) has been developed rapidly, this kind of floodlight than incandescent lamp energy saving 90%, under the same power LED is higher than ordinary fluorescent lamp and high-pressure sodium lamp luminous intensity 40%.

And the life of the LED lamp to l0 thousands of hours.

Color rendering index can reach more than 80, far higher than high voltage sodium lamp. Because use dc constant current pure sine wave power inverter , LED lights not possible stroboscopic.

Therefore. Has become the best green lighting lamps and lanterns.

Subway station with LED lights not only save a lot of electricity and a lot of copper.

But also can save a lot of maintenance costs.

At the same time also can ensure the quality of the lighting.

In view of the present problems of subway lighting systems.

Provides a new structure, low cost. Long service life, energy saving effect is good. High reliability of the lighting solution.
