the light shaping device is arranged on an emergent light path of the collecting lens and comprises a first surface and a second surface opposite to the first surface, the first surface comprises a plurality of first surface structures and second surface structures for shaping incident light, and the first surface structures and the second surface structures have different curvatures;
and the light condensing system is used for collecting and projecting the light beams emitted by the light shaping device to a target plane.
Referring to fig. 1-10, the present invention provides a light source system 10, the light source system 10 includes a light emitting array 100, a collecting lens 200 and a light shaping device 300.
As shown in fig. 1, the light emitting array 100 includes a plurality of light emitting devices 110, and the plurality of light emitting devices 110 may be arranged in an array or a line for generating light beams respectively. Thereby enabling the light emitting array 100 to generate a plurality of light beams. The collecting lens 200 is used to collect the light beams emitted from the light emitting array 100.
In an embodiment, the light emitting device 110 specifically includes an LED chip, or an LED chip plus a fluorescent portion, the fluorescent portion may include a fluorescent powder, and light emitted by the LED chip passes through the same or different fluorescent portions, and may emit a light beam of a single color, or may emit a light beam of a different color, such as a three-primary-color light beam.
As shown in fig. 2 to 5, the light shaping device 300 includes a first surface 311 and a second surface 312 opposite to the first surface 311, wherein the first surface 311 is a light incident surface, and the second surface 312 is a light emitting surface; the first surface 311 includes a plurality of first surface structures 320 and second surface structures 330 for shaping incident light, wherein the plurality of first surface structures 320 are disposed at intervals, and the second surface structures 330 are spaced regions between the plurality of first surface structures 320. It should be noted that in other embodiments, the second surface of the light shaping device, i.e. the exit surface, is provided with a plurality of first surface structures and second surface structures, but of course, the first surface and the second surface of the light shaping device may also be provided with a plurality of first surface structures and second surface structures arranged at intervals.
As shown in fig. 1 and 2, the light beams emitted from the light emitting array 100 are collected by the collecting lens 200 and then incident on the first surface 311 of the light shaping device 300, wherein a part of the light is incident from the first surface structure 320 of the first surface 311, and a part of the light is incident from the second surface structure 330 of the first surface 311. Since the first surface structure 320 and the second surface structure 330 have different surface structures, the light beams transmitted through the first surface structure 320 and the second surface structure 330 have different angle shapes, so that light distribution modulation of the total light beam emergent light is realized.
In other embodiments, the first surface structures 320 and the second surface structures 330 may also be disposed on the second surface 312, wherein the plurality of first surface structures 320 are disposed at intervals, and the second surface structures 330 are spaced areas between the plurality of first surface structures 320. Wherein the first surface structure 320 arrangement and the second surface structure 330 are provided with different surface structures.
The following specifically describes a case where the first surface structure and the second surface structure are different surface structures.
In an embodiment, since the curvatures of the first surface structure 320 and the second surface structure 330 are different, the divergence and the angle adjustment of the light beam are also different, so that the spatial overlapping degree of the light beams emitted through the first surface structure and the second surface structure is different, which directly results in that, in a certain angular space, the light beam emitted from the first surface structure 320 and the light beam emitted from the second surface structure 330 overlap, and in another angular space, the light beam emitted from the first surface structure 320 and the light beam emitted from the second surface structure 330 do not overlap, so that a light spot with uneven brightness distribution can be formed on the target plane, and since the overlapping rate of the light beams in the angular space corresponding to the middle area is the highest, a light spot with the highest middle brightness and gradually reduced brightness from the middle to the periphery is formed.
In embodiment 1, the first surface structure 320 is provided with a first curved surface structure, and the second surface structure 330 is a planar structure.
As shown in fig. 2, the first surface structures 320 correspond to a curved lens, that is, each first surface structure 320 corresponds to a curved lens unit, and the lens unit is configured to converge the incident light beam, so that the light beam incident to the first surface structure 320 converges and exits.
As shown in fig. 2, the second surface structure 330 is a planar structure, i.e. the incident light is vertically incident on the second surface structure 330 and vertically exits through the light shaping device 300, i.e. the light beam exiting from the second surface structure 330 exits along the incident angle, and the angular distribution of the light beam is not changed. Specifically, the plurality of first surface structures are spaced apart, that is, any one first surface structure has a gap with an adjacent first surface structure, and the gaps constitute the second surface structure 330.
As shown in fig. 2, the light emitting array 100 emits a plurality of light beams, which are collimated and emitted after being collected by the collecting lens, and a portion of the light beams are incident from the first surface structure 320 of the first surface 311 of the light shaping apparatus 300, and since the first surface structure 320 has a curved surface structure, the incident light beams are converged and emitted to change the divergence angle of the light beams, such as the light beam L1 in fig. 2, which is incident through the first curved surface structure of the first surface structure 320, and after being converged by the first curved surface structure, the emitted light beams can be divided into two types, and the emission angle of the first type of light beam is unchanged and is emitted perpendicularly to the emission surface, i.e., L12; the exit angle of the second light beam diverges at a certain angle, i.e., L11 and L13, it should be noted that fig. 2 is a cross-sectional view of the light beam, and in a perspective view, L11 and L13 are both light beams diverging around the central optical axis of L1. Another part of the light beam is incident from the second surface structure 330 of the light shaping means 300, and since the second surface structure 330 is a planar structure, the planar surface does not change the angular spread of the incident light, i.e. the light beam will exit at the same angle as the angular distribution at the time of incidence, as shown by L2. In an angle space, the middle region includes not only the light beam L2 with unchanged angle, but also the light beams L11 and L13 after the light beams in the surrounding region are diffused, so that the target plane at this time has a light spot with gradually reduced brightness distribution from the middle to the edge. As shown in fig. 3. It can be seen that the brightness is higher towards the middle, since the central-most region not only comprises the light beam with unchanged beam angle, but also comprises the superposition of other light beams with divergent light distribution in the central region, i.e. all light beams with divergent light distribution via the first surface structure 320 contribute to the brightness of the central-most region.
As shown in fig. 2, the first surface structures 320 may be disposed on the first surface 311 at equal intervals, and the curvatures of the surface structures in the plurality of first surface structures 320 are the same, and in other embodiments, as shown in fig. 4, the first surface structures 320 may also be disposed on the first surface 311 at unequal intervals, and the curvatures of the surface structures in the plurality of first surface structures 320 are different.
For the embodiment in which the first surface structures 320 are arranged at different intervals, the brightness distribution of the light spot emitted by the light source system does not gradually decrease from the center of the light spot to the periphery, but gradually decreases from the non-center area of the light spot to the periphery.
For embodiments in which the curvatures of the first surface structures 320 are different, the shape of the light spot emitted by the light source system is not a circular distribution, and different distributions of emitted light can be achieved by controlling the positions of the first surface structures with different curvatures, for example, emitting a light spot with a gaussian distribution.
In embodiment 2, specifically, the first surface structure 320 is a first curved surface structure, the second surface structure 330 is a second curved surface structure, and the curvature of the first surface structure 320 is different from the curvature of the second surface structure 330, so that the light beam is diffused to different degrees.
As shown in fig. 6 and 7, the second surface structure 330 may be further divided into a plurality of sub-areas 331, and second curved surface structures 332 having a curvature different from that of the first surface structure 320 may be respectively disposed in each of the sub-areas 331 so that an amount of angular change of the light beam incident to the second surface structure 330 is different from an amount of angular change of the light beam incident to the first surface structure 320. Similarly to embodiment 1, due to the amount of diffusion of the light beam incident on the second surface structure 330 and the light beam incident on the first surface structure 320. In an angle space, the central area includes the light beam with less diffusion and the light beam including the diffused light beam in the peripheral area, so that a light spot with gradually reduced brightness distribution from the center to the edge is formed on the target plane compared with the peripheral area.
Specifically, the different curvatures affect the angle change and brightness uniformity of the light beam, so that the effect of higher central brightness of the light spot in the above embodiment can be achieved.
In one embodiment, the first curved structure or the second curved structure may be a spherical mirror.
In one embodiment, the first curved surface structure and the second curved surface structure may be spherical mirrors.
In a specific embodiment, the orthographic projection of the first surface structure 320 on the first face 311 is a circle, a regular polygon or an irregular polygon. That is, the projection of the first curved surface structure on the first surface 311 may be a circle, a regular polygon or an irregular polygon. And the second surface structure 330 is correspondingly shaped.
Preferably, the orthographic projection of the first surface structure 320 on the first surface 311 may be circular, so that the first curved surface structure forms a circular convex mirror, and the incident light beams in different directions can be well angularly adjusted.
Specifically, the material of the light shaping device 300 may be glass or plastic, which has good processability and light transmittance.
Example 3, in particular, the first surface structure 320 may be provided with a diffusion film, and the second surface structure is a plane.
As shown in fig. 8, a diffusion film may be disposed on the light incident surface or the light emitting surface of the first surface structure 320, so as to perform angle shaping on the light beam and diffuse the light beam. Or the first surface structure 320 may be provided with diffusing particles to diffuse the light beam, and the second surface structure 320 is not processed, so that the light beam emitted from the first surface structure 320 and the light beam emitted from the second surface structure 320 are diffused to different degrees.
As shown in fig. 9, the light source system 10 may further include a collecting mirror 400, and the collecting mirror 400 is used for collecting the light beam emitted from the light shaping device 300 and projecting the light beam onto the target plane.
In a specific implementation, the effect of the spot of light transmitted onto the target plane can be controlled by controlling the distance of the collection mirror 400 from the light shaping device 300. Such as the size of the light spot and the number of the light spots, so as to adapt to different application occasions.
As shown in fig. 1, the collecting lens 200 may include a plurality of first lens devices 210, and the plurality of first lens devices 210 may also be arranged in an array or a straight line and respectively correspond to the plurality of light emitting devices 110 one by one. So that each first lens device 210 collects the light beam emitted from its corresponding light emitting device 110; thereby focusing the light beam emitted from the light emitting device 110 to prevent the light beam emitted from the light emitting device 110 from being excessively diffused and to incident the collected light beam on the light shaping means 300.
As shown in fig. 10, the collecting lens 200 may also be a double-layer lens, and further includes a plurality of second lens devices 220, where the plurality of second lens devices 220 respectively correspond to the plurality of first lens devices 210 one by one, and specifically may be disposed on a side of the first lens device 210 away from the light emitting device 110, so as to further focus the light beam focused by the first lens device 210.
Optionally, the diameter of the second lens device 220 is larger than the diameter of the first lens device 210.
In conclusion, in the above-mentioned embodiment, the utility model discloses a luminous array sends multibeam to collect the back through collecting lens, incide on the light shaping device, because the light shaping device includes the first surface structure and the second surface structure that the camber is different, thereby make the light beam carry out different angle plastic, so that when forming the facula on the target plane, the central luminance of facula is greater than marginal luminance.
