Title: Dot array fluorescent tube
Inventor: HATTORI HITOSHI
IPC: H01J31/15
Filed: 1989-03-15
Abstract: PURPOSE:To secure uniformity of light emitting condition by forming a magnetic field directed to the direction where light emitting segment array is seen to the left, in the direction of the light emitting segment array and in a cathode side space zone above a grid. CONSTITUTION:A magnetic field 10 is formed in a cathode side space zone above a lattice-shaped grid 6 in a vacuum space over the entire length of a light emitting segment array 4, with the sense of the magnetic field 10 directed in the direction as shown with the letter B where the light emitting segment 4 is seen to the left. Even if there are thermoelectrons emitted out of a cathode 8 and tend to go via lattice openings of the grid 6 to the exposed portion of an insulation layer 5, the thermoelectrons are bent toward the center line or to the side of the light emitting segment array 4 by Lorentz force due to the magnetic field 10 directed in the direction B, The thermoelectrons are absorbed with the grid lattice portion projecting near a phosphor 3 or pass through the grid 6 and reach the surface of the phosphor 3. This prevents the insulation layer 5 at the lattice-shaped openings of the grid 6 from being charged and secures uniformity of light emitting condition in the array direction.
