Benefits of technology

[0009]In order to resolve the above problems, the present invention provides a backlight unit and the lamp socket thereof. A single lamp socket that can be secured to bezels of different thicknesses is provided, so as to simplify inventory management and significantly lower the mold cost of preparing various lamp sockets.
[0016]In accordance with the present invention, a single lamp socket can be used for bezels of different thicknesses, thereby tremendously increasing flexibility in use. Therefore, the lamp socket can be used for backlight units of different sizes and has superior commonness, and accordingly the production cost and the likelihood of assembly errors in the production line can be decreased.

Problems solved by technology

As a result, manufacturing costs such as mold cost, production and inventory management are greater than if a more versatile design were produced.
Consequently, the throughput is lowered and the rework process is complicated.

first embodiment

[0023]FIG. 1 illustrates a lamp socket in accordance with the present invention, and FIG. 2 and FIG. 3 illustrate the front view and side view of the lamp socket shown in FIG. 1. A lamp socket 10 includes a socket body 11, and the upper portion of the socket body 11 is provided with a flange 12 that is connected to the socket body 11 and horizontally protrudes from the socket body 11. Two support members 13 are connected to the socket body 11 and extend upward. In this embodiment, the socket body 11 includes a first side surface 23 and a second side surface 24 opposite to the first side surface 23. The two support members 13 are placed at the first side surface 23 and the second side surface 24, respectively.

[0024]As shown in FIG. 1 and FIG. 2, in this embodiment, the top of the support member 13 is a stepped structure 14 including a first step 15, a second step 16, a third step 17 and a fourth step 18. Accordingly, the gaps between the stepped structure 14 and the flange 12 corresp...

second embodiment

[0027]FIG. 5 illustrates the lamp socket in accordance with the present invention, and FIG. 6 illustrates the front view of the lamp socket shown in FIG. 5. A lamp socket 20 includes a socket body 11, and the upper portion of the socket body 11 is provided with a flange 12 connected to the socket body 11 and horizontally protruding from the socket body 11. Two support members 43 are connected to the socket body 11 and extend upward. In this embodiment, the socket body 11 includes a first side surface 23 and a second side surface 24 opposite to the first side surface 23. The two support members 43 are placed at the first side surface 23 and the second side surface 24, respectively.

[0028]As shown in FIG. 6, in this embodiment, the support member 43 is a forked structure, and includes at least a first branch 44 and a second branch 45. The gap between the top of the first branch 44 and the flange 12 corresponds to a first engaging width e, and the gap between the top of the second branc...

third embodiment

[0031]FIG. 7 illustrates a lamp socket in accordance with the present invention, in which the lamp socket is engaged with a bezel of a backlight unit. FIG. 8 and FIG. 9 illustrate the front view and the side view, respectively, of the lamp socket shown in FIG. 7. A backlight unit 90 includes a lamp socket 70 and a bezel 80. The lamp socket 70 includes a socket body 11, and the upper portion of the socket body 11 is provided with a flange 12 connected to the socket body 11 and horizontally protruding from the socket body 11. In this embodiment, the socket body 11 includes a first side surface 63, a second side surface 64 opposite to the first side surface 63, a third side surface 65 and a fourth side surface 66 opposite to the third side surface 65. As shown in FIG. 8 and FIG. 9, two support members 73 are placed at the first side surface 63 and the second side surface 64, respectively. The gap between the top of the support member 73 and the flange 12 forms an engaging groove 75 wit...

Abstract

A lamp socket includes a socket body, a flange and a plurality of support members. The flange is connected to the socket body and protrudes from the socket body horizontally. The plurality of support members are connected to the socket body. At least one engaging groove including at least two engaging widths is formed between the plurality of the support members and the flange, so as to secure the socket body to a bezel.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 97145047, filed Nov. 11, 2008. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification.BACKGROUND OF THE INVENTION[0002](A) Field of the Invention[0003]The present invention relates to a backlight unit and the lamp socket thereof, and more specifically, to a backlight unit and lamp socket for panel display applications.[0004](B) Description of Related Art[0005]A backlight unit is one of the key components of a liquid crystal display (LCD). Since liquid crystal is not luminous, the backlight unit is introduced to serve as a light source capable of generating sufficient brightness and even light distribution, so that liquid crystal can display desired images. LCD display is widely used in the electronic devices with great development potential such as desktop monitors, notebook computers, di...
