In recent years, government departments, research institutions, fixture manufacturers, electrical manufacturers and other relevant units are dedicated to energy research, including road lighting, sidewalk lighting, park lighting and garden lighting in the study as well. Lighting the sake of long time, the energy consumption of the lighting system has been a very important consideration.

With the enhancement of public awareness of environmental protection, people are increasingly concerned about energy issues, government departments have energy efficiency as a performance slogan, called on people not only to adopt new energy-efficient lighting systems, in order to make it more energy efficient.

In order to save energy, road lighting timeshare segment control has become a very effective way. Off-peak hours in traffic, traffic and pedestrian flow, road lighting illumination can be decreased. This can be achieved by using a power converter or sub-paced electronic ballasts. Due to the different lighting systems (with a control line or control line), the benefits of using power converter is also different. This article will focus on the power converter and sub-paced electronic ballasts in road lighting applications.

1, power converter timeshare segment control

According to the technical information provided by light manufacturing enterprises, high-pressure sodium lamps or high-pressure mercury lamp light output can be reduced to 50% of its rated value, the life of the light source is not affected; This means that the light source
Visible light output can be reduced to between 30% to 45%. This can be achieved through the use of segmented ballast. In some special cases, the need for ballast in series or in parallel with an auxiliary impedance power converter.

with the control circuit of the power converter (ZRM U6L / T)

The ballast power segmented conversion is achieved through the use of power converter the ZRM U6L and the ZRM U6L / T. The above units are used with two thermistor (PTC) of the power converter.

This will ensure that the minimum holding current, in order to prevent the lights go out in the power conversion circuit.
If the ballast in series or parallel auxiliary impedance structure, you need to use the ZRM S6L type power converter. The ZRM S6L / T with a delay circuit to ensure that the lights in each time to ignite lights rated output state after a few minutes.

ZRM U6L / T with a delay circuit, when the lamp is lit, it lights at 100% light output state for 330 seconds, and then adjust the lamp brightness to reduce to the default value.

When the Pst added control phase 220V ~ 240V any value between lights 100% light output state; When the control phase is open, the lights in the minimum light output state.

So that the operation of the lamp will be reduced in the low power state of the light output of the lamp, so as to achieve the purpose of reducing energy consumption, impact while not interested in the life of the lamp.

Not with the control line power converter (ZRM U6M)

The ZRM U6M a built-in clock will bring up light operation is synchronized with day and night, dimming time can be arbitrarily set in the central control area. The ZRM U6M completely independent work, maintenance-free without any complex control system.
