A pyrene compound is provided. The pyrene compound is represented by Formula 1: wherein Aand Aare as defined in the specification. Further provided is an organic electroluminescent device using the pyrene compound. The organic electroluminescent device has high color purity of blue light and shows long life characteristics. Therefore, the organic electroluminescent device is suitable for use in displays and lighting systems.

Pyrene compounds and organic electroluminescent devices using the same

Provided is a rail assembly fixed to the sides of a storage compartment of a refrigerator, with rail housings supporting rail members that insert and extrude a storage container, and a light source fixed to a rail housing to indicate whether a certain function is being performed in the storage compartment and function as a lamp that illuminates the inside of the storage compartment.

Refrigerator and rail assembly thereof

Disclosed are a refrigerator and a lighting device therefor. Since an optical source, an LED is installed at a height to overlap a guide member, light emitted from the LED is widely dispersed through the guide member. This may allow a user to easily check a discharged degree of ice cubes or water, and to have sophisticated aesthetic feeling. Furthermore, since the optical source is fixed to an optical source accommodation portion by being encompassed thereby, a water leakage prevention function may be enhanced, and an additional coupling member for coupling the optical source may not be required. This may allow the number of components and assembly processes to be decreased, and the production costs to be reduced.

Refrigerator and lighting device therefor

In order to increase the reliability of the parts constituting the basket and to conveniently use the basket and to stably accomplish the operation of the basket, as the shaking of the basket is prevented, there is disclosed a basket operation device of a refrigerator, comprising: a basket freely moved in a back-and-forth direction in the state that the basket is supported by an inner wall of the refrigerator; a rotation shaft supported by the basket and moved with the basket and respectively rotated; a pair of rotation elements supported by both sides of the rotation shaft and rotated at the same angle to guide a movement of the basket when the basket moves in a back-and-forth direction; and a corresponding element formed in the inner wall of the refrigerator in a back-and-forth direction to contact with the rotation elements.
