  • the first connecting structure 150 has a connecting element 152 and a ring-shaped element 154.
  • the connecting element 152 may be, for example, a rib.

  • the height of the first cut-off wall 112 is greater than the height of the second cut-off wall 114. Therefore, a portion of the light emitted by the light source 300 is limited by the first cut-off wall 112 to avoid forming a halo after a portion of the light reflected by the reflector 200 is emitted at an effective angle.

  • the diameter R3 of the third opening 03 is less than the diameter R4 of the fourth opening 04.
  • the second adjusting structure 120 has a base 122 that extends from the second opening 02 toward the first opening 01, and the third adjusting structure 130 is located at the base 122 and protrudes outside the second adjusting structure 120. In this way, the distance between the third opening 03 and the incident surface 210 is less than the distance between the first opening 01 and the incident surface 210.

  • a second cut-off groove G2 is designed to be disposed between the second adjusting structure 120 and the third adjusting structure 130. Since the distance between the third adjusting structure 130 and the incident surface 210 is less than the distance between the second adjusting structure 120 and the incident surface 210, in the design of the second cut-off groove G2, the distance between the wall of the third adjusting structure 130 and the incident surface 210 is less than the distance between the second adjusting structure 120 and the incident surface 210.
  • the second adjusting structure 120 allows the surface surrounding the first opening 01 to be used as a cut-off surface 124 to effectively shield light that is partially projected at an effective angle.
  • the embodiment can comprise a light reflective coating on the inner edge of the wall of the third adjusting structure 130.
  • the embodiment may also comprise a light reflective coating on the outer edge of the wall of the fourth adjusting structure 140.
  • the fourth adjusting structure 140 in the embodiment has a third cut-off groove G3 that is mainly capable of directly shielding a portion of the light directed to the output surface 220 to prevent visual discomfort and to soften the light projected from the output surface 220.
  • the third cut-off groove G3 may also be, for example, a V-groove structure with the opening facing the incident surface 210.
  • the distance L3 between the third adjusting structure 130 and the output surface 220 is less than the distance L4 between the fourth adjusting structure 140 and the output surface 220.
  • a portion of the light incident on the third adjusting structure 130 is not easily affected by the fourth adjusting structure 140. That is, a portion of the light incident on the third adjusting structure 130 can still be effectively reflected and projected from the output surface 220.
  • the lamp module of the present invention comprises a light adjusting element set in the reflector to shade or adjust the light by using the first adjusting structure, the second adjusting structure, the third adjusting structure and the fourth adjusting structure of the light adjusting element.
