Description

A Design Method for Low Illumination Lighting in Light Controlled Areas

technical field

The invention relates to the field of ship lighting systems, in particular to a design method for low-illuminance lighting in lighting control areas.

Background technique

In order to avoid exposing its targets due to light exposure during wartime, combat ships need to conduct light control on aisles, staircases, cabins and other places where light leakage may occur. The above places are collectively referred to as light control areas.

Under normal circumstances, the main lighting in the lighting control area is powered by the AC 220V main power supply, and the main lighting and low-light lights are respectively configured. Low-illumination lighting behind lighting lamps; emergency lighting in light-controlled areas is powered by DC 24V emergency power supply, and low-illuminance lights are also equipped. Repeated configuration of low-light lamps and repeated laying of power cables in the same lighting control space not only occupy space resources, but also increase the demand for power, especially for frigates with tight layout space and strict weight control, it is undoubtedly a waste of precious overall resources. resource.

Contents of the invention

The technical problem to be solved by the present invention is to provide a design method for low-illuminance lighting in a lighting control area. This method can realize the combination of the main lighting low-illuminance lamp and the emergency lighting low-intensity lamp in the lighting control area through an interlocking device. Powered by DC 24V battery charging and discharging system.

The interlocking device in the present invention needs to meet the requirements for the use of low-illuminance lighting in the lighting control area under normal operating conditions and emergency operating conditions of the system, realize automatic switching between main lighting and emergency lighting, and reduce the occupation of overall resources. Therefore, the interlock device must have the following functions:

1. During the light control period, the main power supply is normal, and the low-illuminance lamp is powered by DC 24V rectified by the battery charging and discharging system, providing main low-light illumination for the light control area;

2. During the lighting control period, when the main power supply is out of power, the low-illuminance lights are directly powered by the battery pack, providing emergency low-light illumination for the lighting control area;

3. During the non-light control period, when the main power supply is out of power, the low-illuminance lamp is directly powered by the battery pack to provide emergency low-light illumination for the light control area.

Note: During the period of non-light control, the main power supply is normal, and the low-light lamp does not work. This is implemented by the ship's existing control unit.

After adopting the design method of the invention, the points of low-illuminance lamps and cables are reduced to half of the original, effectively solving the problem of extra occupation of overall resources.

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a schematic diagram of the principle of the interlocking device in the present invention.

In the figure: ZJ and ZK are AC contactor coils, 1ZJ and 1ZK are passive normally closed contacts respectively. The contact capacity of 1ZK depends on the current of the lighting branch.

Fig. 2 is a comparative schematic diagram of the arrangement of low-illuminance lamps before and after the application of the present invention.

Detailed ways

As shown in Figure 1, the low-illumination lighting in zone 1 is powered from the charging and discharging board in zone 1 through the passive normally closed contact 1ZK (DC). In order to realize the main lighting and emergency lighting during the blackout period, two contactors need to be set to correlate the lighting blackout working condition and the main power state respectively, that is, the former is represented by the contactor ZJ, and the latter is represented by the contactor ZK. The ZJ coil takes power from the busbar (AC) of the low-illumination lighting part of the lighting control lighting distribution box configured in the lighting system. When the busbar has power, it means that the main power supply is powered and the ship is in the lighting control working condition. On the contrary, it means that the ship is in a non-light control condition or the main power supply is out of power. The ZK coil takes power from the busbar (AC) of the lighting distribution board in Zone 1. When the busbar has power, it means that the main power supply in Zone 1 is powered. The passive normally closed contact 1ZJ is connected in series in the electrification circuit of the ZK coil.

When the main power supply has power and is in the light control working condition, the ZJ coil is energized, the passive normally closed contact 1ZJ is disconnected, the ZK coil is not powered, the passive normally closed contact 1ZK is closed, and the low-illuminance lighting is bright, and the zone 1 The charging and discharging board provides a rectified DC 24V power supply, thereby realizing the first function to be satisfied by the interlocking device mentioned in the summary of the invention.

When the main power supply is de-energized and under the lighting control condition, the ZJ coil is de-energized, the passive normally closed contact 1ZJ is closed, the ZK coil is de-energized, 1ZK is closed, and the low-illumination lighting is bright, and the DC 24V power supply is provided by the battery pack in zone 1. This achieves the second function.

When the main power supply loses power and is in a non-light control working condition, the ZJ coil loses power, the passive normally closed contact 1ZJ is closed, the ZK coil is not powered, 1ZK is closed, and the low-illumination lighting is bright, and the DC 24V power supply is provided by the battery pack in zone 1 , thereby realizing the third function.

The ship lighting system is generally divided into multiple areas. In Figure 1, only the low-illuminance lighting in the lighting control area of Area 1 is taken as an example to illustrate the principle of the interlocking device. In practice, the interlocking support of other lighting control areas can be expanded as appropriate by referring to Figure 1. road.

It can be seen from Fig. 2 that after adopting the design method of the present invention, the points and cables of low-illuminance lamps are reduced to half of the original, effectively solving the problem of additional occupation of overall resources.
