Claims

[Scope of utility model registration request]

A light amount control means for controlling the amount of emitted light is provided on the upper surface of the illumination device used in an illumination device in which a linear light source is placed above a reflecting plate and a diffuser plate is placed on the opposite side of the reflecting plate with respect to the linear light source. In the light source,
A fluorescent tube for a lighting device, characterized in that the light amount control means is formed as a continuous pattern connecting both ends of the light source made of a conductive material, and also serves as a trigger coat.
