In the present embodiment, the fitting of the light source 2 to the introduction portion 41 means that the light beam incident from the light source 2 enters the introduction portion 41.
The embodiment of the invention guides the light of the light source 2 out by arranging the light guide component 4, has simple structure, fully considers the projection effect of the light and has better lighting effect. Moreover, when the light emitted from the light source 2 is blocked by an obstacle (e.g., the capacitor 3) that is also disposed in the housing 1 and is higher than the light source 2, so that the light cannot be emitted from the blocked direction, the light can be smoothly guided out of the housing 1 through the first inclined plane 411, so that the light can be emitted from the blocked direction, and the light emitted from the outside of the housing 1 is uniformly distributed.
Referring to fig. 1 again, in order to make the light beam exit the guiding portion 42 from different directions and make the final output light beam be uniformly distributed, the guiding portion 41 further includes a second inclined plane 412, and the second inclined plane 412 is used for guiding part of the light beam exiting from the first inclined plane 411 along a direction different from the direction of the light beam exiting from the first inclined plane 411.
