Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
118 words
An adaptor for operation of a high intensity arc discharge lamp comprising: a housing containing an inductor having a trigger winding, an electronic circuit and an electrical outlet; an external electrical plug connected to said housing; said inductor being connected as a current limiting means between said electrical plug and outlet; the electronic circuit including a diac-triac condition and a resistor in series with a capacitor, one side of the diac being connected to the gate of the triac, the other side of the diac being connected to a point between the resistor and the capacitor; the triac being in series with the trigger winding; and said series resistor and capacitor being connected directly across said electrical outlet.
Claim 2
Dependent Claim
118 words
An adaptor for operation of a high intensity arc discharge lamp comprising: a housing containing an inductor having a trigger winding, an electronic circuit and an electrical outlet; an external electrical plug connected to said housing; said inductor being connected as a current limiting means between said electrical plug and outlet; the electronic circuit including a diac-triac condition and a resistor in series with a capacitor, one side of the diac being connected to the gate of the triac, the other side of the diac being connected to a point between the resistor and the capacitor; the triac being in series with the trigger winding; and said series resistor and capacitor being connected directly across said electrical outlet.
Claim 3
Dependent Claim
47 words
The adaptor of claim 1 including a second resistor in series with a second capacitor, the second resistor and second capacitor being connected directly across said electrical plug, and said trigger winding being series-connected between said triac and a point between said second resistor and second capacitor.
