Train lighting lamp with wireless coverage and wired bridging functions

[0016] Such as figure 1 As shown, the present invention provides a train lighting fixture with wireless coverage and wired bridging functions. In the lighting fixture, the centers of gravity or geometric centers of all LED thin film chips are located on the same plane, for example, the centers of gravity of all LED thin film chips are located on the same plane ; For another example, the geometric centers of all LED thin film chips are located on the same plane. Or, on the basis of the above examples, in the lighting fixtures provided in this embodiment, except for one LED thin film chip X, the centers of gravity or geometric centers of the other LED thin film chips are located on the same plane A; on the basis of this example In another example, the LED thin film chip X is parallel or substantially parallel to the plane A, or the light-emitting surface or cross section of the LED thin film chip X is parallel or substantially parallel to the plane A.

[0017] For example, the LED
