Description
FIG. 3 is a cross-sectional view taken along a line I-I shown in FIG. 1;
The connecting part 20 may have a plate shape extended in a longitudinal direction. A plurality of first fixing portions may be formed on a lower surface of the connecting part 20. The first fixing portions may include a plurality of fixing hooks 21 spaced apart from each other by a constant distance. For example, the fixing hooks 21 may be combined with fixing holes formed through the receiving container.
The receiving container 310 includes a bottom plate 311, a first sidewall 313, a second sidewall 315, a third sidewall 317 and a fourth sidewall 319. The first, second, third and fourth sidewalls 313, 315, 317 and 319 are protruded from sides of the bottom plate 311 to form a receiving space. The first and second sidewalls 313 and 315 face each other. The third and fourth sidewalls 317 and 319 face each other, and are connected between the first and second sidewalls 313 and 315. A stepped portion is formed on an upper portion of the first, second, third and fourth sidewalls 313, 315, 317 and 319. A plurality of openings 312 are formed on the bottom plate 311 adjacent to the first and second sidewalls 313 and 315. A second fixing portion may be formed between the openings 312. For example, the second fixing portion may include a plurality of fixing holes 314.
A side of the power supply substrate 330 is inserted into a space between the lower surface of the lamp holder 440 and the inverter connecting part 451. The side of the power supply substrate 330 includes a plurality of output terminals corresponding to the inverter connecting parts 451, respectively. For example, conductive lines formed on the PCB may be partially exposed to form the output terminals. A second aligning part corresponding to a first aligning part formed on the lower surface of the lamp holder 440 may be formed adjacent to the output terminals. For example, the first and second aligning parts may be an aligning protrusion and an aligning hole 335, respectively.
A plurality of fixing portions 377 may be formed on a rear surface of the upper portion 375, and a stepped portion may be formed on the upper surface of the upper portion 375. The fixing portions 377 correspond to the lamp holders 440, respectively. A fixing recess may be formed on an end portion of each of the fixing portions 377. An edge of the fixing recess may have a hook shape. When the side cover 370 is arranged on the bottom plate 311, the first and second lamp connecting parts 455 and 456 are pressed into the fixing recesses. Thus, the first and second lamp connecting parts 455 and 456 may make secure contact with the lead wire 355.
A holding protrusion 459 that is formed on each of the first and second lamp connecting parts 455 and 456 is supported by the fixing recess of the fixing portion 377 so that the first and second lamp connecting parts 455 and 456 are supported by the fixing recess. Thus, the lamps 350 are electrically connected to the power supply substrate 330 through the lamp socket 405.
