- a plurality of guide through holes 4 are defined in the same guide bushing 10, for example, in the present embodiment, two guide through holes 4 are defined inside one guide bushing 10. In this way, one housing 2 may be mounted therein with only one guide bushing 10. Certainly, in other embodiments, it also may be feasible that one guide through hole 4 is defined inside the same guide bushing 10. In this way, when the number of lamp feet 3 is two, one housing 2 needs to be mounted therein with two guide bushings 10. Meanwhile, in the present embodiment, the two guide through holes 4 are separated by the separating plate 41.

- the guide bushing is provided with an abutment post 13, which is configured to be positioned against one side of the light source board 7 (shown in FIG. 15 and FIG. 16 ).
- the inlet end 11 is a large-diameter opening
- the outlet end 12 is a small-diameter opening
- the upper opening transitions evenly and smoothly to the lower opening, then leads 5 at different angles and in different directions may be vertically led out from the lower outlet ends 12 through the guide through holes 4 in the guide bushing 10.
- the guide bushing 10 may be vertically placed in the housing 2, positioned through the cooperation between the guide strip 14 and the guide groove 24 inside the housing 2, and fixed by being pressed against the bottom of the inner wall of the housing 2 and the bottom of the light source board 7, so as to avoid shaking of the guide bushing 10.
- a mounting post 22 and a positioning post 23 are provided inside the housing 2, and the positioning post 23 is configured to cooperate with the positioning hole 71 on the light source board 7, so as to realize guided mounting of the light source board 7.

- the light source board 7 is fixedly assembled with the housing 2 via the screw 9.
- the lens assembly 8 is fixed on the housing 2 by means of snap-fit or gluing, and light emitted from the light source 15 on the light source board 7 can pass through the lens assembly 8 and emit light beams with a specific light beam angle.
- This lens assembly 8 has its own heat dissipation structure, which can be understood as an integration of a lens and a radiator.
- the light source board 7 may adopt a COB light source.
- the COB light source is a high-light-efficiency integrated surface light source technology for directly attaching an LED chip on a mirror metal substrate with high reflectivity. This technology removes the stent concept, and has no electroplating, reflow soldering, and patching procedures, therefore, the procedures are reduced by nearly one third, and the cost is also saved by one third.
