The position of the fixed base plate 5 is relatively fixed, and the fixed base plate 5 and the movable base plate 6 are movably connected, that is to say, the relative position between the fixed base plate 5 and the movable base plate 6 can be adjusted by adjusting the Active connections change.

The light-emitting element 3 is disposed on the upper surface of the movable substrate 6 , and is fixedly and electrically connected to the movable substrate 6 at the same time. The fixed connection means that the light-emitting element 3 is connected to the movable substrate 6 and the relative positions are fixed, and the electrical connection means that the light-emitting element 3 can be energized through the movable substrate 6 . Similarly, for the fixed connection and electrical connection between the light-emitting element 3 and the movable substrate 6, if the light-emitting element 3 is a positive chip, the fixed connection can be realized by gluing, and the electrical connection can be realized by wires; If it is a flip chip, it can achieve fixed connection and electrical connection at the same time by means of solder or conductive glue. In the embodiment of the present invention, the specific type of the light-emitting element 3 may be a VESEL (Vertical-Cavity Surface-Emitting Laser, vertical cavity surface emitting laser) laser chip, or an LED chip.

When the fixed substrate 5 and the movable substrate 6 remain connected and the relative positions change, the light-emitting element 3 arranged on the upper surface of the movable substrate 6 can adjust its light-emitting position according to the position change between the fixed substrate 5 and the movable substrate 6, The light at different angles is realized, and after the light is emitted through the optical cover 4, the light emerges in different light-emitting patterns.

This embodiment provides an optional connection structure between the fixed substrate 5 and the movable substrate 6, as follows:

The upper surface of the bottom substrate 51 is provided with an accommodating groove 53 , and the bottom surface of the accommodating groove 53 includes a first arc surface 71 extending toward the position where the bottom surface of the bottom substrate 51 is located. The movable substrate 6 is arranged in the accommodating groove 53 , and the movable substrate The bottom surface of the The arc surface direction realizes the sliding connection between the first arc surface 71 and the second arc surface 72 ;

The fixed substrate 5 includes a bottom substrate 51 and a sidewall substrate 52 , wherein the bottom substrate 51 is disposed at the bottom, and the sidewall substrate 52 is disposed around the light-emitting element 3 and is fixed in position with the bottom substrate 51 . On the upper surface of the base substrate 51, an accommodating groove 53 is opened. The bottom surface of the accommodating groove 53 is an arc-shaped first arc surface 71, and the bending direction of the arc surface faces the bottom surface of the base substrate 51. The accommodating groove 53 is a downwardly convex structure, please refer to FIG. 3 . The movable base plate 6 is placed in the accommodating groove 53 . The bottom surface of the movable base plate 6 is also an arc-shaped second arc surface 72 . The second arc surface 72 and the first arc surface 71 contact and match each other, please refer to FIG. 4 . The meaning of matching means that the radians between the first cambered surface 71 and the second cambered surface 72 are consistent within the allowable error range, and there may be slight differences, as long as the first cambered surface 71 and the second cambered surface are not limited The sliding between the surfaces 72 in the arc surface direction can be done; and the arc lengths of the first arc surface 71 and the second arc surface 72 are not limited, and the first arc surface 71 may be longer, or the second arc surface 72 longer. Due to the relationship between the first arc surface 71 and the second arc surface 72, a movable connection can be realized between the movable base plate 6 and the bottom base plate 51, and the movable connection is realized by the relative sliding between the two arc surfaces, at least the movable base plate The upper and lower contact relationship between 6 and the base substrate 51 achieves the connection.

By adjusting the relative position, the relative position between the movable substrate 6 and the bottom substrate 51 can be adjusted accordingly, and the light output pattern can be adjusted accordingly. In order to facilitate the manipulation of the sliding shaft 62 , the sliding shaft 62 may also extend out of the outer sidewall of the bottom substrate 51 and protrude outward.

The first locking member may be a separate component, or may be formed by a combination of multiple components.

In some embodiments, the first locking member includes friction surfaces respectively disposed on the first arc surface 71 and the second arc surface 72 . This means that the first arc surface 71 and the second arc surface 72 are rough surfaces with a certain friction factor, which can realize the relative sliding between the first arc surface 71 and the second arc surface 72 in the arc surface direction. When specifying the position, it can rely on its surface roughness to fix its relative position. Since there is no absolutely smooth surface, any surface can be called a rough surface, and the rough surface in this embodiment refers to a surface whose friction factor meets certain requirements, which can make the required relative position, The first cambered surface 71 and the second cambered surface 72 can remain relatively static without applying other external force. When the first locking member is realized by the friction surfaces of the two arc surfaces, its designated position can be any position, in other words, the position adjustment between the first arc surface 71 and the second arc surface 72 is stepless adjustment.
