Thecarrier plate 11 is used to connect and carry afirst light source 12, a firstreflective plate 13, asecond light source 14 and a secondreflective plate 15.

Thefirst light source 12 is used for emitting afirst light 121, and thefirst light source 12 is disposed on one side of the supportingplate 11. Thefirst reflection plate 13 is disposed corresponding to thefirst light source 12. Thefirst reflection plate 13 has afirst focus 131 and asecond focus 132.

The secondlight source 14 is used for emitting asecond light 141, and the secondlight source 14 is disposed on the other side of thecarrier plate 11. Thesecond reflection plate 15 is disposed corresponding to the secondlight source 14. Thesecond reflection plate 15 has a thirdfocal point 151 and a fourthfocal point 152. Thethird focus 151 is, for example, within the oval dotted line on the downward side of thecarrier plate 11 in fig. 2, and the secondlight source 14 is located on thethird focus 151. The range of the fourthfocal point 152 is, for example, within the dotted oval line of fig. 3, and the specific position of the fourthfocal point 152 may be located inside, outside, or overlapping thereflective film 40 of thetransparent substrate 30. The secondreflective plate 15 is used for reflecting thesecond light 141 emitted from the secondlight source 14 on the thirdfocal point 151, so that thesecond light 141 is reflected to the fourthfocal point 152. However, the number of the secondlight sources 14 is not limited to one, and may be changed to a plurality according to the lighting requirements. However, the position of the secondlight source 14 is not limited to being located on the thirdfocal point 151, and the secondlight source 14 may be located near the thirdfocal point 151.

As shown in fig. 1, 2 and 4, in the first embodiment of the present invention, thelens 20 is configured to project the receivedfirst light ray 121 and secondlight ray 141 to the outside to form a low beam pattern a and a high beam pattern B. Thetransparent substrate 30 is disposed between thelight source module 10 and thelens 20, thetransparent substrate 30 is used for supporting thereflective film 40, and the transparent property of thetransparent substrate 30 allows light to pass through, so that a dark band caused by light shielding can be avoided. Thetransparent substrate 30 includes anend surface 31, abottom end 32, and atop end 33. Thebottom end 32 and thetop end 33 are opposite ends, and thebottom end 32 is connected to a bottom housing (not shown) of thevehicle lamp 1. Theend surface 31 has atip 33 facing upward.

As shown in fig. 1 to 4, in the first embodiment of the present invention, thereflective film 40 is a thin film having an optical reflection effect formed by surface treatment, and thereflective film 40 is disposed on theend surface 31 of thetransparent substrate 30. The thickness of thereflective film 40 is less than 0.1mm, and more preferably thereflective film 40 has a thickness in the range of less than 0.05 mm. Thereflective film 40 includes atop surface 41 and abottom surface 42. Thetop surface 41 of thereflective film 40 overlaps the secondfocal point 132, or thetop surface 41 is adjacent to the second focal point 132 (e.g., the area not in direct contact with thetop surface 41 in the range of the dotted line of the secondfocal point 132 in fig. 3). Thebottom surface 42 of thereflective film 40 is connected to theend surface 31 of thetransparent substrate 30. Thebottom surface 42 of thereflective film 40 overlaps the fourthfocal point 152, or thebottom surface 42 is adjacent to the fourth focal point 152 (e.g., in the area of thebottom surface 42 not directly contacting the bottom surface in the dotted line of the fourthfocal point 152 in fig. 3). It should be noted that the positions of the secondfocal point 132 and the fourthfocal point 152 are not limited to the above, for example, the positions of the secondfocal point 132 and the fourthfocal point 152 may be designed to be coincident with each other and located within the range of the dotted line.

As shown in fig. 2 to 4, when thefirst light source 12 emits thefirst light ray 121, a part of thefirst light ray 121 is reflected to thetop surface 41 of thereflective film 40 through the firstreflective plate 13, and then reflected to thelens 20 through thetop surface 41 of thereflective film 40; another part of thefirst light 121 is reflected by the firstreflective plate 13, and then is not reflected to thetop surface 41, but directly emitted to thelens 20. Thelens 20 projects all the received first light rays 121 to the outside to form a low beam type a.

In addition, when the secondlight source 14 emits thesecond light 141, a part of thesecond light 141 is reflected by the secondreflective plate 15 to enter thetransparent substrate 30 and irradiate thebottom surface 42 of thereflective film 40, and is reflected by thebottom surface 42 of thereflective film 40 to pass through thetransparent substrate 30 and irradiate thelens 20. Another part of thesecond light 141, after being reflected by thesecond reflection plate 15 and entering thetransparent substrate 30, does not strike thebottom surface 42, but passes through thetransparent substrate 30 and directly strikes thelens 20. Thelens 20 projects all the receivedsecond light 141 to the outside to form a high beam pattern B. In addition, thefirst light 121 and thesecond light 141 which are not reflected by thereflective film 40 and directly irradiate thelens 20 are mutually bonded to form a bonding region C after being projected to the outside by thelens 20, and the bonding region C is located between the low beam type a and the high beam type B.

Because the thickness of the electroplated metal film of thereflective film 40 is extremely thin, thefirst light 121 and thesecond light 141 are not shielded, so the low beam type a and the high beam type B generated by thefirst light 121 and thesecond light 141 respectively can be attached to each other, and a dark band cannot be generated between the low beam type a and the high beam type B. In addition, the attaching area C formed by thefirst light 121 and thesecond light 141 directly emitted to thelens 20 without being reflected by thereflective film 40 is located between the low beam type a and the high beam type B, i.e. on a dark band caused by a conventional vehicle lamp, so that the light on the attaching area C can further provide an illumination effect to solve the problem of the dark band.
