1. Field of the Invention
The present invention relates to a light emitting module, a lamp device for vehicles including the light emitting module, and a vehicle including the lamp device.
The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which:
FIGS. 1A and 1B are conceptual views of a light emitting module according to an embodiment of the present invention when viewed in different directions;
FIG. 2 is a conceptual view illustrating an optical path of the light emitting module according to the embodiment of the present invention;
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
FIGS. 1A and 1B are conceptual views of a light emitting module according to an embodiment of the present invention when viewed in different directions, and FIG. 2 is a conceptual view illustrating an optical path of the light emitting module according to the embodiment of the present invention.
Referring to FIGS. 1 and 2, a light emitting module 10 according to an embodiment of the present invention includes a condensing lens 30 for condensing incident light into a space in the front, a light source 20 disposed spaced apart from the condensing lens 30 in one direction, a first optical path conversion member 40, e.g., a reflector, disposed spaced apart from the condensing lens 30 in the other direction, which is opposite to one direction, and a second optical path conversion member 50, e.g., a reflector, disposed spaced apart from the condensing lens 30 in one direction, the second optical path conversion member 50 being spaced apart from the light source 20. Specifically, the light emitting module 10 according to the embodiment of the present invention includes a condensing lens 30 for condensing light incident from the rear into a front space, a light source 20 disposed behind the condensing lens 30 to emit first light 21 toward the condensing lens 30, a first optical path conversion member 40 disposed in front of the condensing lens 30 to reflect the first light 21, having passed through the condensing lens 30, and to supply first reflected light 22 to the condensing lens 30, and a second optical path conversion member 50 disposed behind the condensing lens 30 to supply the first reflected light 22, having passed through the condensing lens 30, as second reflected light 23 to pass through the condensing lens 30.
