Technical Field
Embodiments of the utility model relate generally to the field of lighting and/or signaling, and more particularly, to a light guide, a light assembly, and a motor vehicle.
Background
Various lighting and/or signalling devices are used to provide light for lighting and/or optical indication, and are widely used in various fields, for example in motor vehicles for ensuring safe driving by means of lighting devices such as car lights or signalling devices. While various types of lights are often required on motor vehicles to perform different functions, such as high beam lights, low beam lights, fog lights, turn lights, daytime running lights, tail lights, brake lights, and the like. In different types of vehicle lamps, transparent light guides are often used to guide the light source light to obtain a light distribution meeting regulatory requirements or to achieve a specific lighting profile.
However, in the case where the space in which the lamp is located is limited, only a light guide of a limited size can be disposed, which may cause the light-emitting surface of the lamp to be not fully lighted, and thus, the regulatory requirements may not be satisfied, or a specific lighting shape may be realized.

In the above-described two embodiments of the first light guide portion 12, as shown in fig. 1, the end side area a of the light emitting portion 22 of the light guide apparatus 1 cannot be lighted because, if the end side area a is to be lighted, it is necessary to dispose at least one more first light guide portion 12 in the left space of the first light guide element 10, but such a demand cannot be achieved due to space limitation.
In order to solve the above-described problem, as shown in fig. 2, the first light guiding element 10 of the light guiding device 1 according to the present embodiment further includes a second light guiding portion 14, wherein the second light guiding portion 14 is arranged in a space formed by the misalignment of the adjacent two first light guiding portions 12 in the main exit direction. The second light guiding element 20 further comprises a reflecting portion 23, wherein the second light guiding portion 14 is configured to guide light from the light source towards the reflecting portion 23, the reflecting portion 23 being arranged substantially between the second light guiding portion 14 and the light emitting portion 22 in the main exit direction X and configured to reflect light from the second light guiding portion 14 towards an end side area a of the light emitting portion 22, the end side area a being thus capable of being lit.
