FIELD: lighting engineering. SUBSTANCE: night light has cylindrical plug with two electrodes secured in its base; electrodes project on either side of base; electrodes are connected with light sources through resistors; light is also provided with light diffusing screen secured above light source. Dielectric washer made from sticky material is secured to base of plug; similar washer is secured to surface of receptacle and night light is inserted. EFFECT: high safety due to additional pressure force between surface of plug and base of plug due to sticky washers on surface of receptacle and on base of plug. 1 dwg |
