Abstract
Abstract A selectively operable lighting system including a lamp for providing a flame of gas particularly suited for use in illuminating outdoor areas, such as patios, terraces and the like. The system is characterized by a tubular pillar supported by a rigid pedestal embedded beneath the surface of an area being illuminated, and surmounted by a burner connected with a source of gas and encased within a protective and ornamental head. A selectively operable, electrically energizable igniter capable of responding to an absence of an illuminating flame is provided for igniting combustible gas delivered to the burner, whereby a substantially continuous illuminating flame selectively is provided.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
267 words
A gas Lighting system comprising: A. a lamp including a tubular pillar having a substantially uninterrupted external surface supported in a substantially vertical disposition by a rigid pedestal embedded in the surface of an area to be illuminated and surmounted by a gas burner including a gas delivery jet; gas delivery means including a normally closed gate valve remote from said pillar and coupled with a source of combustible gas, and a gas conduit extended from said valve axially through said pillar and coupled with said burner for delivering an uninterrupted flow of combustible gas from the valve to the burner when said valve is opened, whereby a flow of gas is delivered from the jet in response to an opening of the valve; and igniter means disposed adjacent to said jet energizable in response to an electrical signal applied thereto for igniting gas delivered from the jet, said igniter means being de-energizable in response to an adjacent flame of ignited gas; and B. a control circuit including means coupled with said valve and responsive to an electrical signal applied thereto for opening the valve, whereby a flow of gas is conducted through the valve and discharged to said conduit in response to an applied electrical signal; a switching circuit including a photosensitive device electrically coupled with said valve and with said igniter responsive to selected changes in the level of ambient light for selectively applying an electrical signal to said valve and to said igniter, whereby ignition of gas delivered through said jet is achieved in response to selected changes in the level of ambient light.

Claim 4
Dependent Claim
13 words
The system of claim 2 further comprising an ornamental head encasing said burner.
Claim 5
Dependent Claim
16 words
The system of claim 2 further comprising an electrical timer electrically coupled with said control circuit.
