Abstract
A combined frame for housing at least a lamp with one end connected to a power cord is provided. The combined frame comprises a lower frame and an upper frame. The lamp is positioned between the upper frame and the lower frame. The lower frame has an angled cable groove that encloses the power cord from the lamp. One end of the power cord is exposed outside the lower frame. The upper frame is positioned over the lower frame. Through the angled cable groove, the power cord is prevented from sliding in the axial direction of the lamp by any unintended external force and hence pulling power cable away from the lamp. This invention also provides a back light module comprising a light-guiding plate and the aforementioned lamp and combined frame.
Claims19
A combined frame for housing at least a lamp with one end connected to a power cord, comprising:
- a lower frame having an angled cable groove, wherein the power cord is enclosed within the angled cable groove such that the end of the power cord is exposed outside the lower frame;
- and
- an upper frame covering the top section of the lower frame.
A back light module, comprising:
- a light-guiding plate having at least a light-incidenting surface, at least a light-diffusing surface and a light-emitting surface;
- at least a lamp with one end connected to a power cord, wherein the lamp is installed on one side of the light-incidenting surface so that light emitted from the lamp travels to the light-incidenting surface of the light-guiding plate, passes through the light-diffusing surface and emerges from the light-guiding plate via the light-emitting surface;
- a combined frame for supporting the light-guiding plate and the lamp, the combined frame-comprising:
- a lower frame having an angled cable groove, wherein the power cord is enclosed within the angled cable groove such that the end of the power cord is exposed outside the lower frame;
- and
- an upper frame positioned over the lower frame, wherein the upper frame has a window for exposing the light-emitting surface of the light-guiding plate.
