Detailed Description

The present utility model will be described in detail with reference to specific examples. The following examples will assist those skilled in the art in further understanding the present utility model, but are not intended to limit the utility model in any way. It should be noted that variations and modifications could be made by those skilled in the art without departing from the inventive concept. These are all within the scope of the present utility model.

The utility model provides an optical device matched with a plurality of inner matched mirrors with patterns, as shown in fig. 1 and 2, the optical device comprises a first inner matched mirror 110, a second inner matched mirror 120 and a third inner matched mirror 130 which are sequentially arranged along the normal direction 211 of incident light of the luminous surface of LED lamps, the plurality of LED lamps are sequentially arranged along the direction perpendicular to the normal direction 211 of the incident light, namely the luminous source arrangement direction 201 in fig. 2, in practical application, the plurality of LED lamps are closely and linearly arranged along the luminous source arrangement direction 201, and the normal direction 211 of the incident light and the light emergent direction 232 of the optical device are arranged at a certain included angle and are not parallel.

As shown in fig. 3, 4 and 5, the first internal lens 110 includes a first internal lens light incident surface 111 and a first internal lens light emitting surface 112, where the first internal lens light incident surface 111 is a plurality of groups of curved surfaces distributed at equal intervals and equal to the distance between the LED lamps, and a single group of curved surfaces plays a role in uniformly diffusing light along the light emitting source arrangement direction 201, and also realizes a role in deflecting the light path of the optical device in the light emitting direction 232.

Since the first inner lens light incident surface 111 is the light incident surface of the LED lamp, the light emitted from the LED lamp is not diffused and mixed, and therefore, the surface structure corresponding to the LED lamp one by one is needed to be arranged on the first inner lens light incident surface 111 to adjust the light emitted from the LED lamp, therefore, the utility model configures the first inner lens light incident surface 111 to have multiple groups of curved surfaces with the same width as the distance between the LED lamps, each group of curved surfaces comprises two curved surfaces with one large surface curvature and one small surface curvature, the two curved surfaces are spliced at the respective curvature vertexes, the area of the surface with the small curvature is larger than the area of the surface with the large curvature, because the light emitted from the LED lamp passing through the small curved surfaces is most, and the angle between the direction of the light and the first light emitting light 212 needing to deflect is smaller, so that the angle is more gentle; the large curved surface has a large curvature and a relatively steeper occupied area, because the outgoing light passing through the large curved surface is less, but the included angle between the light direction and the first outgoing light 212 to be deflected is larger, so that the curvature is steeper, and the small curved surface is disposed on the inner side of the large curved surface, as shown in fig. 6.

The distance between the light incident surface 111 of the first internal lens and the LED lamp needs to be considered, so that the near distance can cover as much outgoing light of the LED lamp as possible, the light utilization rate is improved, and meanwhile, the appropriate far distance needs to be considered, so that the incident light can be diffused and mixed in the normal direction 211 of the incident light more uniformly. Therefore, when the distance between the first endoscope light incident surface 111 and the LED lamp is controlled to be 2-3 mm, the two points can be simultaneously taken into consideration.

The first inner lens front surface pattern is arranged on the first inner lens light-emitting surface 112, which plays a role of uniformly diffusing light along the light-emitting source arrangement direction 201, so that the first light-emitting light 212 is uniform along the light-emitting source arrangement direction 201 as far as possible, the first inner lens front surface pattern is a plurality of curved surfaces with the same size, and the projection of the curved surfaces in the incident light normal direction 211 is rectangular, as shown in fig. 4, so that the first light-emitting light 212 can be more uniform and finer. The first endoscope front surface pattern may also act as a deflection for the incident light normal direction 211 along the optic light exit direction 232.

As shown in fig. 7, 8 and 9, the second inner lens 120 includes a second inner lens light incident surface 121 and a second inner lens light incident surface 122 that are in contact with the first light emergent surface 212, the second inner lens light incident surface 121 has a function of diffusing light in a direction perpendicular to the light source arrangement direction 201, and also has a function of collimating the light emergent direction 232 of the optical device in a direction perpendicular to the light emergent direction 232, a distance between the second inner lens light incident surface 121 and the first inner lens light incident surface 112 needs to be considered, so that more first light emergent light 212 from the first inner lens light emergent surface 112 can be received by considering a close distance, the light utilization efficiency needs to be improved, and the first light emergent light 212 needs to be diffused uniformly by considering a far distance.

For the second light incident surface 121 of the inner lens, since the LED lamps are linearly distributed in the light source arrangement direction 201 and perpendicular to the diffusion direction, the whole surface can be a curved surface with a larger curvature and no segmentation, so that the first light emitting light ray 212 which is not uniform vertically can be uniform enough in the vertical direction after passing through the second light incident surface 121 of the inner lens when being installed in a use environment, as shown in fig. 9, the second light incident surface 121 of the inner lens presents a continuous curved surface with a small curvature at the center and a large curvature at both ends in the z direction. In addition, since the diffusion requirement of the LED lamp in the z direction is relatively smaller than that in the y direction, and the light has a certain diffusion and light mixing effect after having passed through the first internal lens 110, only one surface similar to an arch shape may be used for the second internal lens light incident surface 121. The side section of the second light incident surface 121 of the inner lens is a shape similar to a paraboloid, the middle of which arches towards the direction of the LED lamp, and the vertex of the second light incident surface is located at the same z-direction height position as the LED lamp, i.e. the same height as the light emitting center of the LED lamp. The focal length of the paraboloid is large, and the primary function is to collimate the first emergent ray 212 which is not too large in the z-direction, and further to reduce the diffusion in the z-direction, so that the ray is kept parallel to the x-direction as much as possible.

It should be noted that the z-direction is understood as the vertical direction when the lens assembly is assembled to a specific use environment, and the vertical direction may be parallel to the vertical direction, or may have a certain included angle with the vertical direction, for example, the included angle is 3 degrees, which is flexibly selected according to the actual use environment.

The second inner lens light emitting surface 122 is provided with a second inner lens front surface pattern, which plays a role of uniformly diffusing in a direction perpendicular to the light emitting source arrangement direction 201, so that the second light emitting light ray 222 is uniform and collimated in the perpendicular direction to the light emitting source arrangement direction 201 as much as possible. The front surface pattern of the second endoscope is a plurality of curved surfaces with consistent sizes, and the projection of the curved surfaces in the normal direction 211 of the incident light is rectangular, which can also be understood as a curved surface pattern with rectangular projection in the x direction, as shown in fig. 8, so that the second emergent light ray 222 can be more uniform.

As shown in fig. 10, 11 and 12, the third inner lens 130 is provided with a third inner lens rear surface pattern on a third inner lens light incident surface 131 contacting with the second light emergent ray 222, the third inner lens light emergent surface 132 is a smooth surface, and the distance between the third inner lens light incident surface 131 and the second inner lens light emergent surface 122 needs to be considered to be close enough on one hand, so that energy loss during light transmission can be reduced, and the light utilization rate is improved; on the other hand, the third lens light-emitting surface 132 is a smooth surface so that a uniform lighting effect can be exhibited as a final surface, and therefore, the distance between the third lens light-entering surface 131 and the second lens light-emitting surface 122 is maintained at 6.5 to 7.5 mm, for example, 7 mm, and the overall effect is preferable.

The effect of the regulation is directly satisfied by adjusting the pattern on the light incident surface 131 of the third internal lens, and the diffusion is further performed in the direction perpendicular to the light emitting source arrangement direction 201. The third endoscope 130 may perform material color conversion for different functions of the optical device, and may be a transparent member, a red member, or the like.

The utility model solves the problems of large space, low utilization rate of the using plane or single curved surface light of the using collimating lens and realizes the effects of uniform diffusion and light path deflection along the normal direction 211 of the incident light by arranging the asymmetric curved surface combination which is spliced by the large curvature surface and the small curvature surface, is equal in number and equal in width and is equidistant to the LED lamp on the first inner lens light incident surface 111. The problem that uniform diffusion is difficult to achieve in the vertical direction of the incident light normal direction 211 is solved by a curved surface structure with small central curvature and large curvature on both sides and similar parabolas on the light incident surface 121 of the second inner lens 120, the light path effect of uniform diffusion and collimation in the vertical direction is achieved, and the problem of considering the regulation value is solved by a small pattern structure on the light incident surface 131 of the third inner lens 130, so that the final lighting effect of considering both regulation and uniform diffusion is achieved.
