A light guide plate (LGP) includes a first surface, a second surface, and a plurality of light incident surfaces. The first surface is a light-emitting surface. The light incident surfaces connect the first surface and the second surface. The second surface has a plurality of ring-shaped grooves. Depths of the ring-shaped grooves are gradually decreased from a place close to a center of the LGP towards places close to the light incident surfaces. Each of the ring-shaped grooves has a first ring-shaped side wall surface and a second ring-shaped side wall surface. The second ring-shaped side wall surface is opposite to the first ring-shaped side wall surface and located between a geometry center of the ring-shaped groove and the first ring-shaped side wall surface. The first ring-shaped side wall surface is a tilted surface. In addition, a light source apparatus is also provided.

A light emitting diode (LED) lamp includes a heat dissipation module, a circular light guide plate (LGP), and LED light sources. The heat dissipation module includes a heat dissipation element and a heat-conducting base that has a containing concave. The heat dissipation element connecting and surrounding the heat-conducting base is distant from the circumference of the heat-conducting base. The circular LGP in the containing concave has a top surface, a bottom surface, and an annular side surface. The top surface faces the heat-conducting base and has concentric annular trenches. The LED light sources are configured in the containing concave and face the annular side surface. The LED light sources are suitable for emitting a light beam which is capable of passing through the annular side surface to enter the circular LGP and capable of being reflected by the annular trenches and emitted from the bottom surface.

A cup assembly includes two sleeves, a bottom element, a ring and bosses. The sleeves are made of paper while the ring and bosses are made of a plastic material. The first sleeve is made with a lower edge and an upper edge. The bottom element is attached to the lower edge of the first sleeve. The ring is formed on the upper edge of the first sleeve. The bosses are formed on the first sleeve against the ring. The second sleeve is made of paper with a lower edge and an upper edge. The lower edge of the second sleeve is located against the bosses as the second sleeve is provided around the first sleeve. Thus, an adequate insulating space is defined between the first and second sleeves.
