The present invention provides a projection module comprising: a light source for emitting light; a first reflector arranged behind the light source, and reflecting the light emitted from the light source as an elliptical shape having one focal point arranged on the light source and the other focal point positioned in front of the light source; a second reflector arranged in one side of the first reflector, and reflecting the light emitted from the light source as an elliptical shape having one focal point arranged on the light source and the other focal point positioned in one side of the front side of the light source; and a third reflector arranged in the other side of the first reflector, and reflecting the light emitted from the light source as an elliptical shape having one focal point arranged on the light source and the other focal point arranged in the other side of the front side of the light source. The present invention makes various beam patterns like a projection module having multiple light sources by arranging the multiple reflectors on one light source and efficiency using the light emitted from the light source. Also, the present invention can reduce production costs because it has a simple structure. |
