Laser white light source 11 can be the lamellar body formula light source, and the required space that occupies of lamellar body formula light source is less, can save the shared space of laser white light source 11 under the prerequisite of guaranteeing light source illumination luminance to can reduce the volume of laser distance light module to a certain extent. As shown in fig. 2, the laser white light source 11 is connected to the heat sink 15, for example, by screws. The inner lens 12 is connected to the heat sink 15, for example, by clamping, screwing or clipping, so that the assembly and disassembly are convenient, and the replacement of the laser white light source 11 or the inner lens 12 is facilitated. The laser white light source 11 is arranged between the heat sink 15 and the inner lens 12, and the inner lens 12 is arranged close to the laser white light source 11, so that more light can be transmitted out of the inner lens 12, and the utilization rate of the light source is improved. The inner lens 12 is a double-convex lens, and can focus light of a light source at one point.
The outer lens 14 is fixedly connected to the lens holder 13, for example, by gluing. As shown in fig. 3, the side of the lens holder 13 remote from the outer lens 14 is connected to a heat sink 15, for example, by screws.

It is understood that the sidewall of the lens holder 13 may be made of a non-transparent color, such as black, or a non-transparent color coating may be applied on the sidewall of the lens holder 13. Moreover, the lens support 13, the inner lens 12 and the outer lens 14 can jointly form an adaptive laser protection device, so that damage caused by laser leakage can be further reduced, and safety of laser illumination is guaranteed. The laser leakage is generally determined based on the energy change of the blue component in the laser light source. That is, when the laser white light source 11 generates laser leakage, the laser beam will ablate the light incident surface of the inner lens 12, so that the laser beam transmitted through the inner lens 12 is no longer focused on the focal position of the outer lens 14, and a part of the laser beam illuminates the inner surface of the lens support 13, and since the light transmittance of the lens support 13 is zero, the lens support 13 can absorb a part of the laser beam, and the leaked laser beam is prevented from transmitting through the lens support 13. Meanwhile, the leaked laser is focused outside the focus of the outer lens 14, and is optically defocused relative to the outer lens 14, that is, the laser passing through the outer lens 14 is expanded again, so that the energy density of the laser can be reduced, and the damage caused by the laser leakage can be reduced.

Further, the radius of curvature of the inner lens 12 ranges from 5mm to 11 mm.
Specifically, the curvature radius range of the inner lens 12 is 5mm to 11mm, the inner lens 12 is a biconvex lens, the focal length of the inner lens 12 is related to the size of the curvature radius of the inner lens 12, and the smaller the curvature radius is, the smaller the focal length is, the better the light condensation effect is, and the utilization rate of light can also be improved to a certain extent. Of course, the curvature radius parameter of the inner lens 12 can be set by those skilled in the art according to actual requirements.
Further, the radius of curvature of the outer lens 14 ranges from 25mm to 30 mm.
Specifically, in order to ensure that the light transmitted through the outer lens 14 is of a high beam type and to improve the utilization rate of the light source, the curvature radius of the outer lens 14 ranges from 25mm to 30 mm. Outer lens 14 is plano-convex lens, changes outer lens 14's curvature radius parameter, can adjust the divergence angle of light, because laser white light source 11 has great luminous flux, compares traditional scheme, can increase the illumination width when guaranteeing distance of distance light illumination. Moreover, the plano-convex lens can also effectively prevent the outer surface of the outer lens from being burnt when the sunlight irradiates. Of course, the curvature radius parameter of the outer lens 14 can be set by those skilled in the art according to actual requirements.
Further, the distance between the light emitting surface of the inner lens 12 and the light incident surface of the outer lens 14 ranges from 38mm to 45 mm.
Specifically, the light source is focused after being transmitted through the light emitting surface of the inner lens 12, the focused light is diffused through the outer lens 14, and the distance between the light emitting surface of the inner lens 12 and the light incident surface of the outer lens 14 can affect the utilization rate of the light source and the diffusion angle of the light, thereby affecting the illumination distance and the illumination width of the laser high beam module. When the distance between the light-emitting surface of the inner lens 12 and the light-entering surface of the outer lens 14 ranges from 38mm to 45mm, the light source utilization rate of the laser high beam module can be effectively improved, and the illumination distance and the illumination width of the laser high beam module can be increased. And compared with the traditional scheme, the geometrical size of the high beam module can be reduced.
Further, referring to fig. 1, the inner lens 12 is provided with a holder 121, and the holder 121 is detachably connected to the heat sink 15.
