Abstract: A lighting device for a vehicle may include: a light source for generating light by an applied power source; and two or more films that allow light generated by the light source to be projected onto a particular shape depending on a pattern. Thermal expansion coefficients of at least two films among the two or more films are different from each other.

Abstract: Disclosed is a graphite component comprising a metal substrate; and a graphite layer formed on the metal substrate. The metal substrate has one or more straight portions and one or more bent portions, which preferably forms a zigzag shape, each bent portion has a round shape, and a number of bent portions is two or greater. The graphite component may improve a heat radiation effect, such that lifespan characteristic and performance of an electronic device may be further improved.

Abstract: Disclosed is a flexible copper clad laminate including a first copper foil layer, a composite layer, and a second copper foil layer. Preferably, the composite layer includes a polyimide layer and a plurality of thermoplastic polyimide layers as an outermost layer thereof being the thermoplastic polyimide layers. In particular, with respect to a total thickness of the composite layer, a total thickness of the plurality of thermoplastic polyimide layers is in a range of from about 15 to about 50%, and a total thickness of the polyimide layer is in a range of from about 50 to about 85%. Each thickness of the first copper foil layer and the second copper foil layer is in a range of from about 30 to about 80 ?m, and the total thickness of the composite layer is in a range of from about 40 to about 60 ?m.

Abstract: A buried interior lamp of a vehicle includes: an illumination portion in which a light source for emitting light is disposed in a buried interior lamp of a vehicle which is inserted into and installed in a vehicle headlining; a pattern layer disposed on the lower portion of the illumination portion to form a specific design of light; a fabric layer disposed on the lower portion of the pattern layer; and a pattern cover layer which is disposed between the pattern layer and the fabric layer and has the same color as a cover so as not to display the pattern layer to the outside when turning off a lamp of the illumination portion.
