Abstract
The invention discloses a reflecting cup lamp which comprises a reflecting cup, a light guiding pillar and a light-emitting diode (LED) lighting part which is coupled with the light guiding pillar. The light guiding pillar is an axial symmetry concrete body made of transparent materials and comprises a rear end face, a side face and a front end face, wherein the side face surrounds the rear end face and extends along the horizontal direction. A first optical curved surface is formed as the periphery of the front end face sinks to the center. A second optical curved surface is formed as the periphery of the rear end face sinks to the center. A third optical curved surface is formed as the periphery of the reflecting cup sinks to the center. The second optical curved surface is a light incoming face. The side and the third optical curved face are light reflecting faces. After arranging the light guiding pillar in front of the LED lighting part, a light source is invisible so that glaring does not occur. Light rays of small angles near the normal direction of the light source can be effectively controlled. Application occasions of the reflecting cup lamp can be expanded. By adjusting positions of the light guiding pillar in the optic axis direction, multiple light emitting angles of the lamp and even continuous adjustment of the light emitting angles are achieved.
