On the Photoelectric Effects of the Various Kinds of Light Source influencing to the Starting Characteristics of the Cold Cathode Type Discharge Tube

냉음극방전관의 기동특성에 미치는 각종광원에 의한 광전효과

It is well known that the starting characteristics of the cold cathode type discharge tube have photoelectric effects by the incident light from outside. After making the cold cathode type discharge tubes to be avaiable for popularizing, the present paper was devoted primaliry to a study of relations between the starting characterstics and photoelectric effects of discharge tube under the oight circumstances of day light, incandescent lamp, flouresent lamp, and mercury lamp we used frequently. The result of this investigation show that the photoelectric effects by flourescent lamp emitting short wave length having close ralation to the photoelectric effects is greater than incandescent lamp or day light, and also mercury lamp emitting shorter wave length than flourescent lamp indicates the greatest photoelectric effects.
