Abstract

A pathway indicating luminaire for use in an auxiliary lighting system contains at least one source of primary light and at least one light emitting diode. A switching system provides energy from a storage cell to the light emitting diode upon certain conditions, generally by time or by lack of ambient light.

Claims

exact text as granted — not AI-modified
1 . A lighting system comprising:
 a) a housing having an upper portion and a lower portion;   b) a primary or main light source mounted proximate the upper portion of the housing; and   c) at least one light emitting diode (LED) proximate the lower portion of the housing.   
     
     
         2 . The lighting system of  claim 1  further comprising a sensor for sensing a level of ambient light or for sensing a level of a main source of power provided for the primary or main light source, the sensor being connected to one of the main source of power and an auxiliary source of power, and the sensor being connected to the at least one LED to selectively control the provision of electricity from the one of the main source of power and the auxiliary source of power to the at least one LED in response to a low level of ambient light or a lack of power to the primary light source. 
     
     
         3 . A lighting system comprising:
 a primary light source; and   a light emitting diode (LED) connected to the primary light source.   
     
     
         4 . The lighting system of  claim 3 , further comprising a sensor for sensing a level of ambient light or for sensing a level of a main source of power provided for the primary light source, the sensor being connected to one of the main source of power and an auxiliary source of power, and the sensor being connected to the LED to selectively control the provision of electricity from the one of the main source of power and the auxiliary source of power to the LED in response to a low level of ambient light or a lack of power to the primary light source.
