摘要： The present invention provides a structure of car lamp comprising a light-guiding element and a light-emitting device. The width of a first body shrinks gradually from a first light-emergence plane to a first light-incidence plane and forming a first side oblique plane and a second side oblique plane. A second body of the light-guiding element includes a second light-incidence plane and a second light-emergence plane. The second light-incidence plane is connected to the first light-emergence plane. The first body includes side oblique planes and oblique planes; the second body includes a third side oblique plane, a reflective plane, and oblique planes. By using the side oblique planes, the reflective planes, and the oblique planes to reflect part of incident light out of the light-guiding element, the reduction of the overall luminous efficacy of the structure of car lamp can be avoided.

摘要： A lighting module is provided for generating two different lighting effects, and includes at least one light source, a first primary optical element, a second primary optical element, and a projection lens. The first primary optical element contains a diffusion surface diffusing the light beams from the light source to homogenously light the projections lens for a first lighting effect. The first primary optical element has a first reflector and second reflector. The first reflector reflects light beams from the light source in a boundary area between the diffusion surface and another section of the lighting module onto the second reflector to direct these light beams through the diffusion surface onto the projection lens. The second primary optical element directs light beams from the light source onto the projection lens to light the projection lens for a second lighting effect.
