Lamp socket, backlight assembly including the lamp socket, and liquid crystal display including the backlight assembly

1. A lamp socket comprising:

a power connection unit which is electrically connected to an electric source which supplies power to a lamp;

a lamp connection unit which is disposed above and adjacent to the power connection unit along a longitudinal axis and is electrically connected to the lamp; and

a fastening member which is disposed on the lamp connection unit and has an outwardly protruding hook portion to be coupled with a unit provided externally,

wherein the lamp connection unit comprises at least one sub-component which has a surface area perpendicular to the longitudinal axis which is larger than the largest surface area of the power connection unit perpendicular to the longitudinal axis and wherein the sub-component of the lamp connection unit with the largest surface area perpendicular to the longitudinal axis is located proximate to the power connection unit.

2. The lamp socket of claim 1 , wherein the fastening member is disposed at opposing sides of the power connection unit.

3. The lamp socket of claim 1 , wherein the fastening member comprises a hook.

4. The lamp socket of claim 1 , wherein the sub-component of the lamp connection unit comprises:

a light-shielding plate;

a first housing which is disposed on the light-shielding plate and is made of an insulating material; and

a lamp connection terminal which is disposed in the first housing and is electrically connected to the lamp.

5. The lamp socket of claim 1 , wherein the power connection unit comprises:

a second housing made of an insulating material; and

a power connection terminal which is disposed in the second housing and is electrically connected to an inverter printed circuit board which supplies power to the lamp.

6. The lamp socket of claim 5 , wherein the power connection unit further comprises a board support, which is interposed between the lamp connection unit and the power connection terminal and supports the inverter printed circuit board.

7. The lamp socket of claim 1 , wherein the sub-component of the lamp connection unit comprises:

a first housing which is disposed adjacent to the power connection unit; and

a lamp connection terminal which is disposed in the first housing and is electrically connected to the lamp.

8. A backlight assembly comprising:

at least one lamp;

a housing unit which receives the at least one lamp and has socket holes corresponding to ends of the at least one lamp; and

lamp sockets which are inserted into the socket holes and are connected to the lamps,

wherein each of the lamp sockets comprises:

a lamp connection unit which is electrically connected to the lamp;

a power connection unit which is disposed below and adjacent to the lamp connection unit along a longitudinal axis and is electrically connected to an electric source which supplies power to the lamp; and

a fastening member which is disposed on the power connection unit and is secured to the socket hole, and has an outwardly protruding hook portion to be coupled with a unit provided externally,

wherein the power connection unit comprises at least one sub-component which has a surface area perpendicular to the longitudinal axis which is larger than the largest surface area of the lamp connection unit perpendicular to the longitudinal axis and wherein the sub-component of the power connection unit with the largest surface area perpendicular to the longitudinal axis is located proximate to the lamp connection unit.

9. The backlight assembly of claim 8 , wherein the lamp socket is inserted into the corresponding one of the socket holes, and

wherein the lamp connection unit is disposed inside the housing unit and the power connection unit is disposed outside the housing unit.

10. The backlight assembly of claim 8 , wherein embossing is disposed around the socket holes.

11. A liquid crystal display comprising:

a liquid crystal panel; and

the backlight assembly of claim 8 which supplies light to the liquid crystal panel.

12. A method of manufacturing a lamp socket, the method comprising:

forming a power connection unit which is electrically connected to an electric source which supplies power to a lamp;

forming a lamp connection unit which is disposed above and adjacent to the power connection unit along a longitudinal axis and is electrically connected to the lamp; and

forming a fastening member which is disposed on the lamp connection unit and has an outwardly protruding hook portion to be coupled with a unit provided externally,

wherein the forming a lamp connection unit comprises forming at least one sub-component to have a surface area perpendicular to the longitudinal axis which is larger than the largest surface area of the power connection unit perpendicular to the longitudinal axis and wherein the sub-component of the lamp connection unit with the largest surface area perpendicular to the longitudinal axis is formed proximate to the power connection unit.
