Problems solved by technology

However, due to part of the discharge electric field E out It is not located in the discharge space, so that the discharge gas 230 cannot be released, but only by the partial discharge electric field E located in the discharge space in The free discharge gas 230 cannot effectively improve the luminous efficiency of the flat fluorescent lamp 200

Embodiment Construction

[0024] FIG. 3A is a partial perspective view of a flat fluorescent lamp according to an embodiment of the present invention, and FIG. 3B is a partial side view of the flat fluorescent lamp of FIG. 3A . Please refer to FIG. 3A and FIG. 3B at the same time. The flat fluorescent lamp 300 of this embodiment mainly includes a first substrate 310, a second substrate 320, a discharge gas 330, an electrode group 340, a dielectric layer 350 and a fluorescent material 360. . The first substrate 310 has a first recess 312, and the second substrate 320 has a second recess 322, and the first substrate 310 and the second substrate 320 are joined together, so that the first recess 312 and the second recess 322 form a discharge Space S. In this embodiment, the first recess 312 and the second recess 322 are respectively formed by a groove, for example, and the cross section of the groove is semicircular. Of course, the cross section of the groove can also be U-shaped, V-shaped (as shown by t...

Abstract

The invention discloses a plane fluorescent lamp, which comprises a first basal plate, a second basal plate, a discharging gas, an electrode group and a fluorescent material. At least one first concave is arranged on the first basal plate; at least one second concave is arranged on the second basal plate; the first and second basal plates are joined with each other to form a discharging space between the first concave and the second concave. The discharging gas, the fluorescent material and the electrode group are all positioned in the discharging space. Wherein, the first concave and the second concave are respectively arranged at two sides of the electrode group, so that the majority of a discharging field provided by the electrode group can be arranged within the discharging space. Therefore, the invention is able to elevate the degree of dissociated discharging gas in the discharging field and enhance the luminance efficiency of the plane fluorescent lamp.

Description

technical field [0001] The present invention relates to a flat fluorescent lamp, and in particular to a flat fluorescent lamp with high luminous efficiency. Background technique [0002] With the advancement of modern video technology, liquid crystal display devices have been widely used in display screens of consumer electronic products such as mobile phones, notebook computers, personal computers and personal digital assistants (PDAs). However, since the liquid crystal display panel of the liquid crystal display device does not have the function of emitting light, it is necessary to configure a backlight module under the liquid crystal display panel to provide the light source required by the liquid crystal display panel, so that the liquid crystal display panel can achieve the display function. At present, the backlight modules on the market are mainly flat fluorescent lamps (Flat Fluorescent Lamp, FFL), cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp, CCFL)...
