       4 . The lamp socket of  claim 1 , wherein the support member is a forked structure. 
   
   
       5 . The lamp socket of  claim 4 , wherein the forked structure comprises at least a first branch and a second branch, the engaging groove comprises a first engaging width and a second engaging width, the first engaging width corresponds to a gap between a top of the first branch and the flange, and the second engaging width corresponds to a gap between a top of the second branch and the flange. 
   
   
       6 . The lamp socket of  claim 1 , wherein the socket body comprises a first side surface and a second side surface opposite to the first side surface, and the plurality of support members are placed on the first side surface and the second side surface. 
   
   
       7 . The lamp socket of  claim 6 , wherein the socket body further comprises a third side surface and a fourth side surface, and the plurality of support members are placed on the third side surface and the fourth side surface. 
   
   
       8 . The lamp socket of  claim 1 , wherein the bezel has a plurality of openings placed corresponding to the plurality of support members. 
   
   
       9 . A backlight unit, comprising:
 a bezel; and   a lamp socket, comprising:
 a socket body; 
 a flange connected to the socket body and horizontally protruding from the socket body; and 
 a plurality of support members connected to the socket body; 
   wherein the plurality of the support members and the flange therebetween form at least one engaging groove having at least two engaging widths for securing the socket body to the bezel.   
   
   
       10 . The backlight unit of  claim 9 , wherein the support member comprises a stepped structure. 
   
   
       11 . The backlight unit of  claim 9 , wherein the support member is a forked structure. 
   
   
       12 . The backlight unit of  claim 9 , wherein the socket body comprises a first side surface and a second side surface opposite to the first side surface, and the plurality of support members are placed on the first side surface and the second side surface. 
   
   
       13 . The backlight unit of  claim 12 , wherein the socket body further comprises a third side surface and a fourth side surface, and the plurality of support members are placed on the third side surface and the fourth side surface. 
   
   
       14 . The backlight unit of  claim 9 , wherein the bezel has a plurality of openings placed corresponding to the plurality of support members. 
   
   
       15 . A backlight unit, comprising:
 a lamp socket, comprising:
 a socket body, and 
 at least one clamping member extending from the socket body to form at least one horizontal engaging groove; and 
   a bezel having at least one bending end that is engaged in the engaging groove, wherein a depth of the engaging groove is greater than or equal to a height of the bending end for engaging the bending end therein.   
   
   
       16 . The backlight unit of  claim 15 , wherein the socket body comprises a flange horizontally protruding from the socket body, and the engaging groove is formed between the flange and the clamping member.
