[0033] In this embodiment, the low-beam lamp bead 41 is arranged at the upper part of the low-beam lamp board 40, the low-beam reflector 30 is arranged above the low-beam lamp board 40, the high-beam lamp bead 51 is arranged at the lower part of the high-beam lamp board 50, the high-beam reflector 60 is arranged below the high-beam lamp board 50, and the light-cutting mechanism 70 is arranged between the low-beam lamp board 40, the high-beam lamp board 50 and the glass lens 10 for performing the light-cutting action of the low-beam light and the high-beam light. Of course, the low-beam lamp bead 41 and the high-beam lamp bead 51 can also be respectively arranged on the upper and lower sides of the same lamp board, and the emission of the low-beam and high-beam lights can also be achieved.
[0034] Referring to the attached Figure 6 As shown, the glass lens 10 in this embodiment adopts a square triple-lens structure composed of three aspherical lenses 11, 12, and 13. Among them, the two small aspherical lenses 11 and 12 are symmetrically arranged on both sides of the upper part of the large square lens 13.
[0035] In this way, after the light emitted by the low-beam lamp bead 41 is reflected by the low-beam reflector 30 and cut by the light-cutting mechanism 70, it is emitted parallel from the lower area of the large square lens 13, as shown in the attached Figure 7 figure, forming the main light pattern of the low-beam and high-beam lights. After the light emitted by the high-beam lamp bead 51 is reflected by the high-beam reflector 60 and cut by the light-cutting mechanism 70, it is emitted parallel from the middle area of the upper part of the large square lens 13, as shown in the attached Figure 8 figure, forming the supplementary light pattern of the low-beam and high-beam lights. The direct-emitting lamp bead includes two, namely lamp bead 21 and lamp bead 22, and is emitted parallel after passing through the two small aspherical lenses 11 and 12, as shown in the attached Figure 9 figure, forming the supplementary light pattern of the high-beam light.
[0036] Specifically, referring to the attached Figure 6As shown, in this embodiment, the vertical distance H between the centers of the two small aspherical lenses 11 and 12 and the central horizontal line of the large square lens 13 is 11 mm, the center distance L between the two small aspherical lenses 11 and 12 is 42 mm, and the radii R of the two small aspherical lenses 11 and 12 are 10 - 14 mm, preferably 11.5 mm.
[0037] In this embodiment, the luminous flux of the high beam lamp bead 51 is set to 800 Lum, and the luminous fluxes of the high beam direct illumination lamp beads 21 and 22 are both set to 600 Lum. Then, the installation positions and dimensions of the above two small aspherical lenses 11 and 12 are explored, and it is obtained that:
[0038] Appendix Figure 10 shows the high beam supplementary light pattern of the square double direct illumination double light LED automotive headlamp obtained under the conditions of L = 42 mm, R = 10 mm, and H = 11 mm. The obtained output luminous flux is 173 Lum, and the maximum brightness at the high beam center is 21100 cd, that is, the output luminous flux is low, the high beam height and brightness are poor, and the light pattern is not very ideal.
[0039] Appendix Figure 11 shows the low beam supplementary light pattern of the square double direct illumination double light LED automotive headlamp obtained under the conditions of L = 42 mm, R = 10 mm, and H = 11 mm. The obtained output luminous flux is 78.3 Lum, and the maximum brightness at the center is 18700 cd, that is, the output luminous flux is high, the low beam width and brightness are both good, and the light pattern is ideal.
[0040] Appendix Figure 12 shows the high beam supplementary light pattern of the square double direct illumination double light LED automotive headlamp obtained under the conditions of L = 42 mm, R = 11.5 mm, and H = 11 mm. The obtained output luminous flux is 646 Lum, and the maximum brightness at the high beam center is 87600 cd, that is, the output luminous flux is high, the high beam height and brightness are both good, and the light pattern is ideal.
[0041] Appendix Figure 13 shows the low beam supplementary light pattern of the square double direct illumination double light LED automotive headlamp obtained under the conditions of L = 42 mm, R = 11.50 mm, and H = 11 mm. The obtained output luminous flux is 68 Lum, and the maximum brightness at the center is 15800 cd, that is, the output luminous flux is low, the low beam width and brightness are poor, and the light pattern is relatively ideal.
[0042] Appendix Figure 14 shows the high beam supplementary light pattern of the square double direct illumination double light LED automotive headlamp obtained under the conditions of L = 42 mm, R = 14 mm, and H = 11 mm. The obtained output luminous flux is 616 Lum, and the maximum brightness at the high beam center is 93400 cd, that is, the output luminous flux is high, the high beam height and brightness are both good, and the light pattern is ideal.
[0043] Attached Figure 15 The figure shows the low beam fill light pattern of the square dual direct dual light LED car headlamp under the condition of setting L = 42mm, R = 14mm, H = 11mm. The output luminous flux is 58Lum, and the maximum brightness at the center is 12200cd, that is, the output luminous flux is low, the low beam width and brightness are poor, and the light pattern is poor.
[0044] From the results in the above figure, it can be seen that, considering the emitted luminous flux, brightness of the light pattern, and width angle, the radius R of the aspheric lenses 11 and 12 is in the range of 10-14mm, and the high and low beam effects are better. When the optimal value is 11.5mm, it can have both high and low beam effects and meet the high-end needs of automobile headlights.
