Wherein, this reflector plate covers the end metal plate in back of the body metal plate, and the side of this reflector plate stretches in the L type lamp plate and be overlapping with side plate.
Wherein, this reflector plate is fitted on the back of the body metal plate by adhesive glue.
Wherein, this light source is a kind of in cathode fluorescent tube, thermal cathode fluorescent tube, external electrode fluorescent lamp pipe and the light emitting diode.
Wherein, this light source is fixed on the back of the body metal plate by keeping rubber.
Wherein, this L type lamp plate is sheet metal component or working of plastics.
Wherein, has plurality of bump on the side plate of this L type lamp plate.
Wherein, have a plurality of breach on the side metal plate of this back of the body metal plate, each breach is corresponding with each projection on the L type lamp plate, and this back of the body metal plate is chimeric fixing by breach, projection and L type lamp plate.
Wherein, this L type lamp plate is fixed by screw and back of the body metal plate.
Positive progressive effect of the present invention is:.
The fluorescent tube reflex housing of the lamp plate replacement cost costliness of L type is processed in use, inwall at L type lamp plate attaches one deck reflectance coating, with L type lamp plate and back of the body metal plate combination fixing after, thereby play and the same effect of original fluorescent tube reflex housing, reduced the material cost of backlight.And, L type lamp plate and back of the body metal plate by bayonet socket mode such as chimeric or screw fix, easy to assembly, improved the packaging efficiency of backlight greatly.
