Preferably, the fog lamp further comprises a control switch (not shown) connected to the first LED light source 310 and the second LED light source 410. The on-off of the first LED light source 310 and the second LED light source 410 is controlled through the control switch, when near light is needed, the second LED light source 410 is turned off, only the first LED light source 310 is turned on, when far light is needed to be irradiated, the first LED light source 310 and the second LED light source 410 are simultaneously turned on, so that the switching between the far light and the near light is realized, and the problems that the traditional mechanical shading mechanism consumes energy and is easy to cause jamming and the like are avoided.
Preferably, one side of the light shielding sheet 60 close to the lens 50 is an arc structure, and the center of the arc corresponds to the focal point of the lens 50. The side of the light shielding sheet 60 close to the lens 50 is an arc-shaped structure 610, that is, the side of the cross section of the light shielding sheet 60 close to the lens 50 is a curve, so that the illumination light beam images the curve at a distance through the lens 50 into a straight line, and the light type is not influenced. In this embodiment, the shade 60 is a very thin stainless steel sheet having a thickness of 0.08mm to 0.3mm, preferably 0.1 mm. The arc-shaped structure 610 is a concave surface, that is, the cross section of the arc-shaped structure is concave, that is, one side of the stainless steel sheet close to the lens 50 is arc-shaped, and the center of the arc is located near the focal point of the lens 50, it should be noted that the more the light near the focal point, the brighter the illumination light spot is finally formed, and therefore, part of the light which cannot be converged near the focal point is converged near the focal point after being reflected by the first reflection area or the second reflection area, and finally exits through the lens 50 to improve the brightness of the illumination light spot.
Preferably, the first reflective region and the second reflective region of the light shielding sheet 60 are both plated with reflective films. In this embodiment, the upper and lower surfaces of the light shielding sheet 60 are plated with reflective films to form a first reflective region and a second reflective region, for example, plated with aluminum or silver, or plated with other metals with high reflectivity, so as to ensure that light is reflected as much as possible. The first reflective region and the second reflective region may be symmetrically or asymmetrically distributed with respect to the light-shielding sheet 60. The first reflective region and the second reflective region may be the same or different in shape and size. In this embodiment, the first reflective region completely covers the upper surface of the light shielding sheet 60, and the second reflective region completely covers the lower surface of the light shielding sheet 60.
Preferably, the light path turning member 420 at least includes a first reflecting surface 421 and a second reflecting surface 422, the light path turning member 420 may be a light reflecting bowl, which includes two reflecting surfaces, the first reflecting surface 421 is a curved reflecting surface, the second reflecting surface 422 is a planar reflecting surface, the curved surface is an approximately elliptical surface, the light emitted from the second LED light source 410 is reflected twice by the curved reflecting surface and the planar reflecting surface, the planar reflecting surface may be regarded as an equivalent light source surface of the second LED light source 410, and the top of the planar reflecting surface is as close as possible to a horizontal line corresponding to the light emitting surface of the first LED light source 310, so as to reduce the distance between the light emitting surface of the first LED light source 310 and the light emitting surface of the second LED light source 410, on the other hand, since the distance between the light emitting surface of the first LED light source 310 and the light emitting surface of the second LED light source 410 is smaller or even 0 distance, the condition that there is no light or few light in the middle area of the lens 50 is improved, the light efficiency and the light energy utilization rate of the whole system are effectively improved. Of course, the optical path turning member 420 may be other optical elements as long as the above-mentioned effects can be achieved.
