The present invention relates to a lamp holder and a lamp assembly using the same, and more particularly, a lamp wire which disconnects a lamp wire for supplying power to the lamp and a lamp wire that is prevented from being shorted by contact with another conductive member such as a lamp reflector. It relates to a holder and a lamp assembly using the same.                         

In general, a liquid crystal display (LCD) has an electro-optical characteristic of a liquid crystal (LC), specifically, a predetermined electric field between two transparent electrodes in a state in which a liquid crystal is injected between the two transparent electrodes. As a result, the display device may display a character, an image, and a moving image by using characteristics in which light transmittance of the liquid crystal is changed.

The liquid crystal display device defined as described above is widely used in a display device of a portable computer, a monitor for a desktop computer, a display device of a mobile phone, and the like because the liquid crystal display device has a smaller volume and weight than a CRT display device, which is a typical display device.

Since the liquid crystal, which is essential for performing a display in such a liquid crystal display device, only adjusts the amount of light transmitted but does not produce light by itself, light is required in order to allow a user to recognize the result data processed by the information processing device.

At this time, the light required to perform the display from the liquid crystal display is obtained by two methods.

The first method is to use light generated from sunlight, indoor lighting, etc. existing outside the liquid crystal display.

The second method uses a light produced in itself by consuming electric energy stored in the liquid crystal display.

Each of these first and second methods has advantages and disadvantages.                         

 The first method, that is, the display using the light generated from sunlight, indoor lighting, etc., is very effective in terms of power consumption, but has a fatal disadvantage that the display cannot be performed at all in a dark place.

The second method, that is, a method of performing display using light produced by consuming electric energy stored in the liquid crystal display device, has a disadvantage in that power consumption is large, but can be displayed freely anywhere regardless of the external environment of the liquid crystal display device. Due to the advantage of being able to perform most of the liquid crystal display device performs the display using this method.

In this case, in order to perform the display of the liquid crystal display by the second method, an apparatus for generating light necessary for the display is required.

As a device for generating light required to perform the display of the liquid crystal display, a lamp, a lamp wire for supplying power to the lamp, and a lamp holder for supporting a lamp coupled to the lamp wire In addition, a lamp reflector which emits light emitted radially from the lamp in one direction is required.

At this time, when there is a problem in the structure of the lamp wire and the lamp holder supporting the lamp, for example, when the lamp holder does not sufficiently absorb external force applied from the outside, the lamp wire coupled to the lamp holder is disconnected, and the lamp When the wire is broken, the lamp driving power is not applied to the lamp, so that information display from the liquid crystal display is impossible.                         

In another example, when the lamp holder does not insulate the stripped wire portion of the lamp wire from other conductive members while the lamp wire is coupled to the lamp holder, for example, the wire of the lamp wire and the lamp reflector Short-circuit causes lamp deterioration and fire.

For this reason, there is an urgent need for the development of a technology in which the disconnection of the lamp wire coupled to the lamp holder and the lamp wire are not shorted with other conductive members.

Accordingly, the present invention is to meet the above-mentioned conventional problems and technical development needs, and a first object of the present invention is to provide a lamp holder such that a disconnection or short of a lamp wire for supplying power to a lamp does not occur.

In addition, a second object of the present invention is to provide a lamp assembly including a lamp holder to prevent the disconnection or short of the lamp wire for supplying power to the lamp.

The lamp holder for implementing the first object of the present invention has a body portion is formed with a coupling hole for fitting a plurality of lamp electrodes on the first side, the lamp wire is inserted into the second side to supply power to the electrode ; And a lamp wire fixing means integrally formed in the body and fixing and insulating the lamp wire located outside the coupling hole.                     

In addition, a lamp assembly for implementing a second object of the present invention includes a lamp having a first, a second electrode and a first, second lamp wire for applying power to the first and second electrodes on both sides of the lamp tube; A body portion having a coupling hole for holding a first lamp wire for holding a first electrode on a first side and a power supply to the first electrode on a second side, and an outer circumferential surface of the first lamp wire protruding outside the coupling hole A first lamp holder comprising a first lamp wire fixing tube protruding from the body portion to surround the body; A body portion having a coupling hole for holding a second electrode end on a first side and holding a second lamp wire for supplying power to the second electrode on a second side, of the second lamp wire exposed to the outside of the coupling hole. A second lamp holder including insulating partition walls protruding from both sides of the coupling hole to fix and insulate the electric wire; And a lamp reflector configured to reflect light emitted radially from the lamps coupled to the first and second lamp holders in one direction.

The insulating partitions 252, 254, and 256 are installed to include the openings 220b formed in the first surface 211.

Such a structure prevents the wire portion from being shorted in contact with another conductive member, for example, a lamp reflector, while the wire portion of the lamp wire is exposed to a portion not coupled to the lamp holder body 230, and the lamp wire is prevented. It acts to prevent flow and disconnection.

In this way, the lamp wire insulated from the other conductive member by the insulating barrier wall 250 is applied to the lamp by using a first voltage, which is a reference voltage required for driving the lamp, and a first voltage, which is alternating with respect to the first voltage, to the lamp. do.
