摘要： A backlight assembly includes a planar fluorescent lamp, a heat-discharge member and a bottom chassis. The planar fluorescent lamp includes a lamp body, a first external electrode and a second external electrode. The lamp body emits light, the first external electrode is formed on an upper face of the lamp body and the second external electrode is formed on a lower face of the lamp body. The heat-discharge member is coupled to the planar fluorescent lamp allowing the heat-discharge member to make contact with the first and second external electrodes. The bottom chassis includes a bottom portion and a side portion to receive the planar fluorescent lamp and makes contact with the heat-discharge member. Thus, the backlight assembly may effectively discharge heat generated from planar fluorescent lamp and prevent a pin-hole defect.

摘要： A backlight assembly includes a receiving container having a receiving space, a flat-type light source, an optical member, and an inverter. The flat-type light source has a plurality of light emitting spaces spaced apart from each other and is received into the receiving space. The optical member has a prism pattern formed in areas corresponding to areas between adjacent light emitting spaces and disposed at a light emitting direction of the flat-type light source. The inverter generates a voltage for the flat-type light source. The prism pattern 1o includes prisms having a substantially trigonal prism and continuously connected one after another. Thus, the backlight assembly may improve brightness uniformity thereof and have a reduced thickness.

摘要： A lens for a light emitting diode is formed with a material having a refractive index of n, and the lens includes a base, a first curved circumferential surface extending from the base, a curved center-edge surface extending from the first curved circumferential surface, and a curved centermost surface extending from the curved center-edge surface. The base includes a groove for receiving a light emitting chip therein. In the lens, a distance from a center of the base to a point of the curved center-edge surface is always shorter than the radius of curvature for the point of the curved center-edge surface. The curved centermost surface has a concave shape with respect to the base. In addition, when an obtuse angle formed between a main axis of the lens and a tangent line of a point of the curved centermost surface is A1, and an acute angle formed between a straight line linking the center of the base to the point of the curved centermost surface and the main axis of the lens is A2, the lens satisfies the equation: A1+A2

摘要： A light-generating device includes a driving substrate and a plurality of light source arrays. The driving substrate has a rectangular planar shape. The plurality of light source arrays is formed on the driving substrate. The light source arrays include at least one light emitting diode to generate light in response to power being applied through the substrate, and the light source arrays are spaced apart from each other. Thus, heat generated from the light-generating device is rapidly dissipated from the light-generating device, improving brightness of the light, brightness uniformity of the light and color reproducibility of the light.
