Ambient light controlled outdoor gas light

摘要

An outdoor lamp has a solenoid valve which controls the feed of gas and mixed with air to an electrically conducting venturi table and thence to burner tips which are surrounded by mantles. An electrode disposed adjacent to a slit in the venturi tube creates a spark adjacent to the slit when the valve is electrically opened to light the gas mixture which subsequently lights the gas mixture at the tips. An electrical circuit has a photocell array which causes the electrical circuit to open the valve at dawn with a shot of electricity and closes the valve at night with another shot of electricity. A sensor in the circuit detects when the lamp is lighted and discontinues the spark.
