Abstract
PURPOSE: To obtain a bulb which is strong in the coating intensity and in possession of beautifully looking fluorescent coat by forming a fluorescent coat on the surface of the glass bulb after fluorescent material has been suspended in alcoholic solution of inorganic compound in low melting point.
CONSTITUTION: Inorganic compound in low melting point, such as boric anhydride is dissolved in alcohol, such as ethyl alcohol or another, this solution is added calcium halophosphate fluorescent material which is cooperative keep-alive with antimony and manganese, which is stirred to be suspension that is heated for drying and removing ethylene, alcohol, and electrostatic coating is done on soda quartz glass bulb which is heated up with obtained fluorescent material particle. This facilitates to obtain a bulb which is strong in the coating intensity and in possession of beautifully looking fluorescent material coat.
