Both ends of the light reflecting cup are provided with openings, the opening caliber of one end where the vertex is located is smaller than that of the opposite end, the opening of one end where the vertex is located is used for assembling a light source, and light rays emitted by the light source are emitted from one end of the large opening after being reflected by the light reflecting cup.
Fig. 2 is a schematic view of a three-dimensional structure of a reflective cup provided in an embodiment of the present invention, as shown in fig. 2, an outer surface 2 of the reflective cup is irregular, and the outer surface 2 gradually inclines toward the inside of the reflective cup from a large opening end to a small opening end of the reflective cup. The design can reduce the volume of the reflecting cup, so that the reflecting cup is suitable for being installed in various lighting devices.
On the basis of the scheme, as a possible implementation mode, the inner surface 1 of the reflecting cup is a reflecting surface; the parabolic equation of the bus is y212x, where y is the axis of rotation of the surface of revolution.
The light emitted by the light source irradiates the reflecting surface of the reflecting cup, and is transmitted along the reflecting direction after being reflected. The reflecting surface actually changes the original propagation direction of light, so that the light emitted by the light source can propagate in the required direction after being reflected, and the light energy can be effectively utilized. The parabolic equation of the reflecting surface generatrix is y2After the light emitted by the light source is reflected by the reflecting surface, the irradiation distance can reach 600 meters, and the propagation distance of the light is increased.
