摘要:
A liquid crystal display module with a thermal passage between a bottom chassis and top chassis is presented. The liquid crystal display module includes a top chassis and a bottom chassis. The top chassis has an inwardly elongated contact protrusion on a lateral cover. The contact protrusion connects the lateral cover and a side wall of the bottom chassis. Here, near the contact protrusion, a light source of the liquid crystal display module is located, and at least a portion of the light source heat can migrate outside rather than being trapped inside of the liquid crystal module.

An LED lamp includes a curved lamp cover, a lamp case coupled to the lamp cover at one open end thereof, and a reflective plate fastened to the lamp case. The lamp case has an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted. The lamp case is divided into a first housing portion and a second housing portion. The first housing portion has a hollow space in which the drive module is fixedly installed. A mounting member configured to mount the LED modules thereon is installed in the second housing portion. Each of the LED modules includes a printed circuit board (PCB) substrate attached to the mounting member, a plurality of LED devices mounted on the PCB substrate, a lens seated on the PCB substrate to diffuse light from the LED devices, a spacer ring inserted between the PCB substrate and the lens, and a color film bonded to the lower surface of the lens facing the LED devices to determine the color of light from the LED modules.

A light emitting diode (LED) lamp for street lighting is provided. The LED lamp includes a curved lamp cover, a lamp case coupled to the lamp cover at one open end thereof, and a reflective plate fastened to the lamp case. The lamp case has an inner space in which a drive module for driving the lamp and a plurality of LED modules as light sources are mounted. The lamp case is divided into a first housing portion and a second housing portion. The first housing portion has a hollow space in which the drive module is fixedly installed. A channel-shaped mounting member configured to mount the LED modules thereon is installed in the second housing portion. The inner surface of the channel-shaped mounting member has two bends to form a central area and first and second side areas formed at both sides of the central area. The areas of the inner surface of the channel-shaped mounting member disperse light from the LED modules in different directions.
摘要:
A backlight assembly, which can provide improved display features by preventing a lamp assembly from being loosened from a lower receiving container, and a liquid crystal display apparatus including the backlight assembly. The backlight assembly includes a light guiding plate guiding incident light, a lamp assembly disposed at one or more sides of the light guiding plate, and having at least one lamp to generate light and a lamp cover enclosing the lamp, a lower receiving container having a bottom plane and sidewalls formed around the periphery of the bottom plane and receiving the lamp assembly and the light guiding plate, and at least one elastic and conductive gasket including a hot-melt adhesive agent having a melting point greater than or equal to about 60° C. and interposed between the lamp cover and the lower receiving container.
