Below, a kind of specification of the plane fluorescent light of expression present embodiment.
The width W of discharge vessel 1: size=750mm * 450mm * 4mm, each discharge cell 13: 6.5mm, height H: 2.4mm.
Discharge medium: mercury=100mg, establish neon and argon is 9: 1,8kPa by weight.
Luminescent coating 14a: the thickness=10 μ m of particle diameter=5.0 μ m, layer.
Luminescent coating 14b: the thickness=150 μ m of particle diameter=2.4 μ m, layer.
Between outer electrode 15a1~15c2:20mm * 143mm, the adjacent electrode every d=5.5mm.
Be connected transducer 3a, 3b, 3c by lead-in wire respectively with on the outer electrode 15a1 of the plane fluorescent light that these constituted and 15a2,15b1 and 15b2,15c1 and the 15c2.That is to say, be formed with on the plane fluorescent light electric on independently 3 luminous group, can carry out independently lighting with being made as luminous group of C between outer electrode 15c1 and the 15c2 with being made as luminous group of A between outer electrode 15a1 and the 15a2, will being made as luminous group of B between outer electrode 15b1 and the 15b2 as shown in Figure 4.The luminous timing of this luminous group of A~C can be controlled by the controller 3 that is connected on transducer 2a, 2b, the 2c.
