Abstract
An automatic night light which will change its illumination in response to changes in the ambient light level. The circuit comprises an AC input with the lamp and a solid-state switch connected in series, a resistive voltage divider being connected across the solid-state switch and having series-connected fixed and light-sensitive resistors. The switch gate is connected to the voltage divider tap by a bidirectional conductor. The structure comprises a housing having circuit and lamp portions. The circuit portion has outlet prongs with bent-back ends, a circuit board being supported by notches in the housing and the prong ends. The housing also supports spring contacts which connect the circuit board to the lamp socket in a simple manner, with the light-sensitive device being easily mountable and firmly supported by the housing.
