The voltage level and power supply mode of lamps installed at 8 m or less from the ground shall comply with the following requirements:

1) A type of luminaire should be selected;

2) The marker light set on the ground should be selected as the centralized power supply type A luminaire;

3) Residential buildings without fire control room, evacuation walkways, stairwells, etc. can choose to have their own power B-type lamps.

The specifications of the sign lights shall comply with the following regulations:

1) For indoor heights greater than 4.5m, extra large or large sign lights should be selected;

2) For indoor heights of 3.5m to 4.5m, large or medium-sized sign lights should be selected;

3) For indoor heights less than 3.5m, medium or small sign lights should be selected.

3) When the sign surface of the direction sign lamp is perpendicular to the evacuation direction, the installation pitch of the lamp shall not exceed 20m; when the sign surface of the direction sign lamp is parallel to the evacuation direction, the installation pitch of the lamp shall not exceed 10m.


(This is a general place. The main thing is that there are two installation methods for this luminaire. One installation is parallel to the evacuation direction, one is perpendicular to the evacuation direction, and the luminaire perpendicular to the evacuation direction is definitely parallel due to visibility. The luminaire, so the installation distance of the luminaire parallel to the direction of evacuation is small, 10m, vertical 20m)


2. Evacuation passages in open space spaces such as exhibition halls, shops, waiting rooms (ships), civil aviation lounges, and business halls shall comply with the following provisions:

1) When the wall, column and other structures are installed on both sides of the evacuation channel, the direction sign lamp should be placed on the wall surface and the cylinder surface below the ground height of 1m; when there are no walls, columns and other structures on both sides of the evacuation channel, the direction sign The light should be placed above the evacuation channel.

2) When the sign surface of the direction sign lamp is perpendicular to the evacuation direction, the setting distance of the extra large or large direction sign lights shall not exceed 30m, and the setting pitch of the medium or small direction sign lights shall not exceed 20m; the sign surface of the direction sign lamp and When the evacuation direction is parallel, the setting distance of the extra large or large direction marker lights shall not exceed 15m, and the setting pitch of the medium or small direction marker lights shall not exceed 10m.

2. Medical buildings, elderly care facilities, public buildings with a total construction area of more than 100,000 m2 and underground and semi-underground buildings with a total construction area of more than 20,000 m2 shall not be less than 1.0 h.

3. Other buildings should not be less than 0.5h.

4. The urban traffic tunnel should meet the following requirements:

   1) Class I and Class II tunnels should not be less than 1.5h, and the station building connected to the tunnel port should not be less than 2.0h;

   2) The third and fourth tunnels should not be less than 1.0h, and the station connected to the tunnel port should not be less than 1.5h.
