Abstract

An emergency lighting and evacuation guidance system includes an emergency lighting and evacuation guidance arrangement which is electrically connected to a commercial electricity supply, and a complementary green power assembly which is electrically connected to the emergency lighting and evacuation guidance arrangement. When the commercial electric supply is cut off during an emergency, the power generated by the complementary green power assembly is supplied to the emergency lighting and evacuation guidance arrangement, whereby the emergency lighting and evacuation guidance arrangement guides people to evacuate and escape during the emergency.

Claims

1. An emergency lighting and evacuation guidance system, comprising:

an emergency lighting and evacuation guidance arrangement, which is electrically connected to a commercial electricity supply, comprising

at least one emergency evacuation guidance arrangement which is provided in a building for providing an evacuation information during the emergency, said evacuation information is selected from a group consisting of a runner safety exit sign, a text safety exit sign, an evacuation map, an indication information of a location of the emergency, and the combinations thereof, and

at least one emergency lighting arrangement, which is provided at a location selected from a group consisting of a corridor, a staircase, an evacuation passage, a safety exit of the building, and the combinations thereof, for providing a lighting during the emergency;

a complementary green power assembly which is electrically connected to the emergency lighting and evacuation guidance arrangement, wherein when the commercial electric supply is cut off during an emergency, the power generated by said complementary green power assembly is supplied to said emergency lighting and evacuation guidance arrangement, whereby said emergency lighting and evacuation guidance arrangement guides people to evacuate and escape during the emergency, wherein said complementary green power assembly comprises at least one photovoltaic power generation arrangement and at least one wind electric power generation arrangement;

a storage battery assembly, wherein said complementary green power assembly and the commercial electricity supply are both electrically connected to said storage battery assembly, wherein said emergency lighting and evacuation guidance arrangement is powered by said storage battery assembly, wherein said photovoltaic power generation arrangement and said wind electric power generation arrangement are electrically connected to said storage battery assembly, so that the power generated by said photovoltaic power generation arrangement and said wind electric power generation arrangement is stored in said storage battery assembly; and

a normally closed relay which electrically connecting said storage battery assembly with the commercial electricity supply, wherein said emergency evacuation guidance arrangement further comprises a first power-down activation switch and at least one emergency evacuation indication lighting, wherein said first power-down activation switch is electrically connected to said normally closed relay, said storage battery assembly, and said emergency evacuation indication lighting, wherein when the emergency takes place and the commercial electricity supply is cut off, said normally closed relay is switched off, and said first power-down activation switch is automatically switched on to electrically connect said storage battery assembly and said emergency evacuation indication lighting in such a manner that said storage battery assembly provides an electricity supply to said emergency evacuation indication lighting.

2. The emergency lighting and evacuation guidance system, as recited in claim 1, wherein said emergency evacuation indication lighting is an LED lamp which is provided for displaying a safety exit sign and a text sign.

3. An emergency lighting and evacuation guidance system, comprising:

an emergency lighting and evacuation guidance arrangement, which is electrically connected to a commercial electricity supply, comprising

at least one emergency evacuation guidance arrangement which is provided in a building for providing an evacuation information during the emergency, said evacuation information is selected from a group consisting of a runner safety exit sign, a text safety exit sign, an evacuation map, an indication information of a location of the emergency, and the combinations thereof, and

at least one emergency lighting arrangement, which is provided at a location selected from a group consisting of a corridor, a staircase, an evacuation passage, a safety exit of the building, and the combinations thereof, for providing a lighting during the emergency;

a complementary green power assembly which is electrically connected to the emergency lighting and evacuation guidance arrangement, wherein when the commercial electric supply is cut off during an emergency, the power generated by said complementary green power assembly is supplied to said emergency lighting and evacuation guidance arrangement, whereby said emergency lighting and evacuation guidance arrangement guides people to evacuate and escape during the emergency, wherein said complementary green power assembly comprises at least one photovoltaic power generation arrangement and at least one wind electric power generation arrangement;

a storage battery assembly, wherein said complementary green power assembly and the commercial electricity supply are both electrically connected to said storage battery assembly, wherein said emergency lighting and evacuation guidance arrangement is powered by said storage battery assembly, wherein said photovoltaic power generation arrangement and said wind electric power generation arrangement are electrically connected to said storage battery assembly, so that the power generated by said photovoltaic power generation arrangement and said wind electric power generation arrangement is stored in said storage battery assembly; and

a normally closed relay which electrically connecting said storage battery assembly with the commercial electricity supply, wherein said emergency lighting arrangement comprises a second power-down activation switch and at least one light illuminator, wherein said second power-down activation switch is electrically connected to said normally closed relay, storage battery assembly, and said light illuminator, herein when the emergency takes place and the commercial electricity supply is cut off, said normally closed relay is switched off, and said second power-down activation switch is automatically switched on to electrically connect said storage battery assembly and said light illuminator in such a manner that said storage battery assembly provides an electricity supply to said light illuminator.

4. The emergency lighting and evacuation guidance system, as recited in claim 3, wherein said light illuminator is an LED lamp.
