The reflecting unit D4 may be disposed under the supporting unit D2, and two sides of the reflecting unit D4 are respectively connected to the first fixing member D21 and the second fixing member D22 of the supporting unit D2. The reflective unit D4 has a reflective surface D40, and the reflective surface D40 may correspond to the second light guide unit D3 and the lower rib D202. In addition, there may be a fourth predetermined included angle A4 between the reflective surface D40 and the first light source emitting surface 110, or between the reflective surface D40 and the second light emitting surface 120, and the fourth predetermined included angle A4 may be between 120 and 150 degrees; , The fourth predetermined included angle A4 can preferably be between 130 and 140 degrees, and 135 degrees is the best, but this creation is not limited to this.

Furthermore, as shown in FIGS. 26 and 27, the second light guide unit D3 may further include a sixth light-emitting surface D35, the sixth light-emitting surface D35 may be connected to the fifth light-emitting surface D34, and the sixth light-emitting surface D35 is connected to the fifth light-emitting surface D34. The connection R of the five light-emitting surface D34 can be rounded, acute or right-angled. In this embodiment, rounded corners are taken as an example, but it is not limited thereto. There may be a fifth predetermined included angle A5 between the sixth light-emitting surface D35 and the fifth light-emitting surface D34, and the fifth predetermined included angle A5 may be between 70 and 110 degrees.

The light-emitting surface D34, the sixth light-emitting surface D35, and the junction R are scattered away from the second light guide unit D3, and projected onto the reflective surface D40 of the reflective unit D4. Then, the first light beam L1 is projected to the lens module 2 through the reflection of the reflective surface D40, so that after the first light beam L1 is projected by the lens module 2, it can fall on the top of the formed low beam light pattern, that is, fall on The range above the HV point (that is, the cut-off line) can further strengthen the after-light area Y (compare the brightness of the after-light area Y in Figure 29 with the brightness of the after-light area Y in Figure 9.

Therefore, when the lighting device Z of this creation projects a light beam, when the first light guide unit D1 does not completely cover the light-emitting surface 110 of the first light source (this creation is not limited to this), the first light-emitting unit 11 borrows A part of the first light beam L1 generated by the light-emitting surface 110 of the first light source (that is, the part far away from the optical axis 22 of the lens) will directly enter the lens module 2 without being refracted by the optical module D. After being projected by the lens module 2, part of the first light beam L1 will fall below the cut-off line of light and dark, away from the area of the cut-off line; while the other part of the first light beam L1 is located in the light-emitting surface 110 of the first light source The light-emitting point closer to the optical axis 22 will change its route through the refraction of the first light guide unit D1 of the optical module D (as shown in FIGS. 33 and 34), and then enter the lens module 2 to cause another After being projected by the lens module 2, part of the first light beam L1 can fall on the edge of the formed light pattern (that is, the cut-off line), and fall on a fixed angle range below the HV point.

In other words, after the first light beam L1 enters the first light guide unit D1, it will leave the first light guide unit D1 after being refracted twice, and then it will be projected onto the test screen through the lens module 2. For the light type (as shown in Figure 9), the cut-off line of the light and dark will fall in a fixed angle range below the HV point. The fixed angle range can be -0.57° ± 0.3°, but this creation is not limited to this.

However, as shown in FIG. 32, the first light-incident surface D11 may also be approximately parallel to the first light-emitting surface D13, and have a second inclined angle B2 of 1 to 15 degrees with the first light-emitting surface D13. The second light-incident surface D12 and the second light-emitting surface D14 may be parallel to each other, but the second light-incident surface D12 may also be approximately parallel to the second light-emitting surface D14, and has a first light-emitting surface D14 of 1 to 15 degrees. Three tilt angle B3. In addition, a fourth oblique angle B4 of 35 to 55 degrees can be formed between the second light incident surface D12 and the optical axis 22, wherein the fourth oblique angle B4 is preferably 40-50 degrees, and 45 degrees is the best. Therefore, the first light guide unit D1 may be a parallelogram or a quadrilateral.

Furthermore, the contact position P of the second light-incident surface D12 and the first light-emitting surface D13 may be located between the optical axis 22 of the lens module 2 and the central axis 110a of the first light-emitting surface 110 of the first light-emitting unit 11. For example, as shown in FIG. 31, the position P of the second light incident surface D12 and the first light output surface D13 of the present creation is between the optical axis 22 and the central axis 110a, that is, the area above the optical axis 22 , And the contact position P corresponds to the position of the cut-off line, and the contact position P is preferably located near the optical axis 22 of the lens module 2. Furthermore, the contact position P between the second light-incident surface D12 and the first light-emitting surface D13 of the present creation can also be located above the focal point 21 of the lens module 2 and below the central axis 110a of the first light-emitting surface 110. That is, the contact position P can be located between the optical axis 22 and the central axis 110a of the first light-emitting surface 110, wherein a position closer to the optical axis 22 is preferred, or the contact position P can be located above the optical axis 22 and close to The lower reference surface 110c of the first light-emitting unit 11, wherein the lower reference surface 110c is adjacent to or on the edge of the first light-emitting surface 110; in addition, the lower reference surface 110c of the first light-emitting unit 11 can also be connected to the The surfaces of the lower edge side 110b of the first light emitting unit 11 overlap and are coplanar.
