By adopting the light-emitting device 200 in the embodiment of the application, some light rays penetrate through the upper side of the tail lamp 11 to form a piano key light-emitting effect, and some light rays penetrate through the rear part of the tail lamp 11 to form a penetrating effect, so that on one hand, more light-emitting areas can be ensured, the warning effect is better, and the safety is realized; on the other hand, the red-black phase luminous effect of the upper side and the rear side has aesthetic property.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the embodiments of the present application, and are not limited thereto; although the embodiments of the present application have been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the spirit and scope of the technical solutions of the embodiments of the present application.
