Lamp holder and lamp assembly having same {A LAMP HOLDER AND A LAMP ASSEMBLY HAVING THE SAME}

The present invention relates to a lamp holder and a lamp assembly having the same, and more particularly, to a lamp holder and a lamp assembly having the same to prevent the soldering portion is disconnected by an external force.

In general, a liquid crystal display device converts a molecular array by applying a voltage to a specific molecular array of the liquid crystal, and changes in optical properties such as birefringence, photoreactivity, dichroism, and light scattering characteristics of the liquid crystal cell that emit light by the conversion of the molecular array. The display device converts the image into a visual change to display an image.

The liquid crystal display device has a smaller volume and weight than the CRT display device, and can be implemented with almost the same resolution, thereby replacing the conventional CRT display device.

However, such a liquid crystal display device requires light due to the characteristics of the liquid crystal, and the light is supplied from light supplied from the outside of the liquid crystal display device, for example, solar light, indoor illumination light, or a device provided inside the liquid crystal display device. It can be supplied by consuming electrical energy.

In particular, in the case of a liquid crystal display device using light generated by consuming electrical energy, a cold cathode ray tube lamp having a long length and a long use time may be used while a long length and a small diameter can be realized.

As a device for generating the light required to perform the display of the liquid crystal display device, a lamp, a lamp wire for applying a driving voltage to the lamp, a lamp holder for supporting the lamp connected to the lamp wire, and light emitted radially from the lamp in a predetermined direction And a lamp reflector for exiting.
