Lighting system
First Claim
1. A lighting system comprising:
- a first lighting circuit configured to provide a first predetermined level of lighting intensity and to receive power from a mains electricity supply or from a battery source if said mains supply is unavailable, said first lighting circuit connected to at least one first light source and configured, when actuated, to provide lighting at said first predetermined level of lighting intensity wherein said first light source is in either an on or off state or at a level of light required to raise ambient light levels above a predetermined level; and
a second lighting circuit configured to provide lighting at least a second predetermined level of lighting intensity, said second lighting circuit configured to receive power from a mains electricity supply and being connected to at least one second light source, said second lighting circuit having a separate control circuit to the first lighting circuit, the second lighting circuit having at least one sensor input such that actuation of said sensor causes said second light source to provide said second predetermined level of lighting intensity;
for a predetermined period of time;
in response to ambient illumination meeting or exceeding a predetermined intensity;
when said sensor has no input or has had no input for a predetermined period of time;
or until re-set;
wherein said second predetermined level of lighting intensity is greater than said first predetermined level of lighting.

Abstract
A lighting system (1) has a first lighting circuit (2) configured to provide a first predetermined level of lighting intensity. The first lighting circuit (2) is configured to receive power from a mains electricity supply (3) or from a battery source (4) if the mains supply is unavailable. The first lighting circuit (2) is connected to at least one first Light source (5) and configured, when actuated, to provide lighting at the first predetermined level of lighting intensity. At this time, the first light source is in either an on or off state or a level of light required to raise ambient light level above a predetermined level. The system (1) further has a second lighting circuit (13) configured to provide lighting at least a second predetermined level of lighting intensity. The second lighting circuit (13) is configured to receive power from the mains electricity supply (3) and is connected to at least one second light source (14). The second lighting circuit (13) has at least one sensor (18) with an input such that actuation thereof causes the second light source (14) to provide the second predetermined level of lighting intensity for a predetermined period of time, in response to ambient illumination meeting or exceeding a predetermined intensity, when said sensor has no input or has had no input for a predetermined period of time, or until re-set. In the system (1), the second predetermined level of lighting intensity is greater than said first predetermined level of lighting.

14. An emergency lighting system comprising:
-
a first lighting circuit connected to at least one LED lighting element, a mains electricity supply, and a battery source, said first lighting circuit being configured to actuate said at least one LED lighting element of said first lighting circuit if said mains supply is unavailable and provide light at a first predetermined emergency intensity; a second lighting circuit connected to at least one LED lighting element, said second lighting circuit including a separate control circuit to the first lighting circuit, the second light circuit being configured to actuate said at least one LED lighting element of said second lighting circuit to provide light at a second predetermined intensity when said mains electricity supply is available, said second lighting circuit having a sensor input adapted to detect availability of the mains electricity supply; and wherein said second predetermined intensity is greater than said emergency intensity. - View Dependent Claims (15)
