Example 1

As shown in fig. 1 to 3, an optical module 100 includes a light guide element 110, a reflector 120 and a lens 130.

The reflector 120 is connected to the light guide element 110. The edge of the lens 130 is connected to the edge of the reflector 120.

The reflector 120 and the lens 130 form an optical space (not labeled) in which the light guide element 110 is located.

As shown in fig. 3 to 6, the light guide element 110 includes a first light incident surface 111, a first light emitting surface 112 and a second light emitting surface 113. The first light incident surface 111 is not damaged, and the inclined surface (the second light emitting surface 113) near the edge can be partially damaged.

As shown in fig. 4, the longitudinal section of the light guide element 110 is a wedge shape in which two shortest sides are connected to each other, as viewed from a sectional view of the light guide element 110. I.e. the light guiding element 110 is designed according to a wedge plate. The wedge-shaped plate is also called as an inclined plate, and one side of the wedge-shaped plate is thick and the other side of the wedge-shaped plate is thin and is in a wedge shape (triangle shape) when viewed from a light incident position.

The three-dimensional structure of the light guide element 110 is a truncated cone; preferably a right circular truncated cone. As shown in fig. 5, the first light incident surface 111 is an upper bottom surface of the truncated cone; as shown in fig. 6, the first light emitting surface 112 is a lower bottom surface of a truncated cone; the second light emitting surface 113 is a sidewall of the truncated cone. In terms of geometry, the bottom surface with the shorter diameter of the circular truncated cone is called an upper bottom surface, and the bottom surface with the longer diameter is called a lower bottom surface, and is irrelevant to the direction.

The light guide element 110 is formed by using an optical acrylic/PC board and then using a high-tech material having a very high refractive index and no light absorption, and a light guide point (not shown) is printed on the bottom surface of the optical acrylic board by using laser engraving, V-cross grid engraving, and UV screen printing techniques.

As shown in fig. 6, a groove 1101 is disposed at the center of the first light emitting surface 112, the groove sidewall 1102 is an arc-shaped curved surface protruding inward, and the longitudinal cross section of the groove sidewall 1102 is an arc shape.

When the light guide element 110 is manufactured, the inner surface of the light guide element 110 is a reflective structure, and light can be totally reflected at the middle of the first light emitting surface 112 and the second light emitting surface 113. When the light beam propagates to the edge of the light guiding element 110 at the edge of the first light-emitting surface 112 and the second light-emitting surface 113, the incident angle is smaller than the total reflection angle, and the light beam directly exits by breaking the total reflection, so that the light beam can exit at the edge of the first light-emitting surface 112 and the second light-emitting surface 113.

As shown in fig. 8, the recess 121 is recessed from a surface of the reflector body; the light guide element 110 is located in the recess 121.

The first reflecting surface 1212 and the second reflecting surface 1213 are integrally formed at the time of production.

The depth of the recess 121 of the reflector 120 increases from the center thereof to the edge thereof and then decreases, specifically, at the first reflecting surface 1212, the depth of the recess 121 increases from the center thereof to the edge thereof; in the second reflection surface 1213, the depth of the recess 121 decreases again from the edge portion thereof.

In other embodiments, the depth of the recess 121 of the reflector 120 decreases from its center to its edge. Therefore, the shape of the recess 121 is a slope or an arc-shaped curved surface as viewed from the cross section thereof. That is, the cross-sectional shape of the reflecting surface 1211 is a slope or an arc-shaped curved surface.

Generally, the light emitted from the second light emitting surface 113 of the light guiding element 110 is reflected to the lens 130 through the second reflecting surface 1213, and the inclination angle of the cross section of the second reflecting surface 1213 requires a certain requirement, so that the depth of the recess 121 needs to be gradually reduced when the first reflecting surface 1212 is used, and the inclination angle of the cross section of the second reflecting surface 1213 requires a certain requirement when the second reflecting surface 1213 is manufactured, so that the light can be reflected to the edge region of the lens 130 through the second reflecting surface 1213.

In one embodiment, the optical module 100 further includes a ring connector 230 connecting the light guide element 110 and the reflector 120.

The lens 130 homogenizes the light emitted from the light guide element, so that the light is collimated and emitted from the third light emitting surface 132, and then reaches a predetermined range of an incident angle of the target surface.

The second light incident surface 131 and the reflection surface 1211 enclose an optical space (not shown), and the light guide element 110 is located in the optical space.

The second light incident surface 131 is a fresnel sawtooth structure, and is formed by injecting and pressing a polyolefin material, and the sawtooth shape is a bezier curve. The second light incident surface 131 is a saw-toothed structure formed by a plurality of concentric circular protrusions, the concentric circular structure includes a plurality of annular grooves, the diameters of the annular grooves are sequentially arranged from small to large, the longitudinal section of each annular groove is triangular, and the saw-toothed structure can better collect light and uniformly transmit the light to the third light emitting surface 132.

As shown in fig. 3 and 11, the third light emitting surface 132 has a bead surface structure, and the bead surface structure is a honeycomb structure formed by a plurality of hexagonal protrusions. The light rays from the second light incident surface 131 can be better gathered and emitted by the bead surface structure, and the light distribution meets the requirement of the emergent angle of the required illumination scene by the bead surface structure, so that the irradiation effect of the spotlight can be achieved.
