The current spatial light source technology includes a refraction type and a reflection type, wherein the refraction type changes the propagation direction and the path of light mainly through the shape of a lens, so that the light intensity at a specific spatial relative position is uniformly distributed. However, the light emitted into the space through the lens has low light intensity and poor uniformity, and the light in the space has a relatively obvious bright-dark overlapping part. The reflecting type mainly realizes the uniform distribution of light intensity at the relative position of a specific space through designing reflecting interfaces (such as cylindrical surfaces, conical surfaces, prism table surfaces and the like) with different shapes, for example, a hopper-shaped rectangular table backlight source adopts a rectangular table surrounded by four isosceles trapezoid plane reflectors, an LED lamp is arranged in the rectangular table, light is emitted to the outside through the reflectors, but the central light intensity of the light emitted based on the mode is high, the edge light intensity is low, and the uniformity is also low.

Referring to fig. 1 to 3, the light unifying unit includes: a lamp holder 101 for placing a light source 102; the lamp holder comprises a first light reflecting structure 103 fixed on the lamp holder 101 and a second light reflecting structure 104 arranged around the periphery of the first light reflecting structure 103, wherein the first light reflecting structure 103 is provided with a first light reflecting surface 1 facing the second light reflecting structure 104, the second light reflecting structure 104 is provided with a second light reflecting surface 2 facing the first light reflecting structure 103, the first light reflecting surface 1 and the second light reflecting surface 2 enclose a light passing area 10, the light passing area 10 is right opposite to the light source 102, and the first light reflecting surface 1 and the second light reflecting surface 2 are used for reflecting light rays emitted by the light source 102 to the outside; the light homogenizing sheet 105, the light homogenizing sheet 105 covers the opening of the light passing area 10, and the light emitted by the light source 102 is transmitted to the outside through the light passing area 10 and the light homogenizing sheet 105.

The light emitted from the light source 102 will be reflected by the first reflective surface 1 and the second reflective surface 2 for multiple times and then emitted to the outside. After multiple reflections, the emergent light of the light source 102 will form overlapped and uniformly dispersed light in the light-transmitting area 10, so that the emergent light has high uniformity. Moreover, since the light-transmitting area 10 is defined by the first light-reflecting surface 1 and the second light-reflecting surface 2, the light emitted from the light source 102 is positioned in the light-transmitting area 10 regardless of the reflection, so that the light emitted to the outside is less lost, and the uniformity is high.

In some embodiments, the light source 102 may be LED lamps arranged at intervals, light emitted from the LED lamps has a certain angle, and when the LED lamps are arranged at intervals, light emitted from the LED lamps to the external space will be independent light spots, so that uniformity is poor. And after the emergent light of LED lamp is reflected many times by first reflection of light face 1 and second reflection of light face 2, the light of a plurality of LED lamps will be by homodisperse to make the light intensity highly uniform of the light of emergent to external space, improve the homogeneity.

Specifically, in some embodiments, the light emitted from the light source 102 has a certain angle of divergence, and therefore, will irradiate onto the first reflective surface 1 and the second reflective surface 2 simultaneously, the light irradiated onto the first reflective surface 1 will be reflected onto the second reflective surface 2, the light irradiated onto the second reflective surface 2 will be reflected onto the first reflective surface 1, and after multiple reflections, the reflected light will form uniformly overlapped and dispersed light. The light rays pass through the light transmitting area 10 and then pass through the light homogenizing sheet 105, and are emitted to the outside after further light homogenizing of the light homogenizing sheet 105, so that the emitted light spots have high illuminance consistency. The utility model provides an even light subassembly is applicable in different equipment and different scenes, for example can be applied to brush the face, sweep the sign indicating number, brush payment type and the clearance floodgate machine class equipment of palm, perhaps live the light filling of equipment, still can be applied to the light filling demand of different scenes.

The first light reflecting structure 103 and the second light reflecting structure 104 are fixed on the surface of the lamp holder 101, and may specifically be bonded to the surface of the lamp holder 101 by using a mechanical fixing structure or an adhesive. Second light reflecting structure 104 encircles in first light reflecting structure 103 periphery, so, can form one between first light reflecting structure 103 and second light reflecting structure 104 and lead to light zone 10, that is to say, second light reflecting structure 104 is the loop configuration to the light zone 10 that leads to that forms is the annular, makes also for the annular through the light that leads to light zone 10 outgoing, and annular facula appearance is preferred, can improve the interactive nature between light and the people. Specifically, in some embodiments, the first light reflecting structure 103 and the second light reflecting structure 104 may be two independent structures, that is, there is no connection relationship between the first light reflecting structure 103 and the second light reflecting structure 104, and in other embodiments, the first light reflecting structure 103 and the second light reflecting structure 104 may also be an integrated structure, and it is only necessary that the light source 102 passes through the light passing region 10 between the first light reflecting structure 103 and the second light reflecting structure 104 and exits to the outside.

In some embodiments, the projection shape of the first light reflecting structure 103 on the surface of the lamp holder 101 may be an annular shape, that is, the first light reflecting structure 103 is also an annular structure, so that the first light reflecting structure 103 is a hollow structure, and devices such as a camera can be arranged in the hollow structure, thereby meeting the light supplement requirements of the devices such as a camera. It is understood that the ring shape referred to herein means a shape having a hollow structure, and may be a triangular ring structure or other polygonal ring structures. In some embodiments, the first light reflecting structure 103 and the second light reflecting structure 104 may have the same shape, for example, both may have a triangular ring shape, such that when the second light reflecting structure 104 is disposed around the periphery of the first light reflecting structure 103, the light passing area 10 is formed to have the same shape as the first light reflecting structure 103 and the second light reflecting structure 104, i.e., also have a triangular ring shape. In other embodiments, the shapes of the first light reflecting structure 103 and the second light reflecting structure 104 may be different, and the shapes of the first light reflecting structure 103 and the second light reflecting structure 104 may be set based on different requirements or user preferences.

Referring to fig. 2 and fig. 3 specifically, in some embodiments, the first reflective structure 103 and the second reflective structure 104 are both circular structures, that is, the first reflective surface 1 and the second reflective surface 2 are curved surfaces, and the second reflective surface 2 is a concave surface, so that when the light emitted from the light source 102 is reflected to the second reflective surface 2, the second reflective surface 2 can reflect the light to the first reflective surface 1 again, and due to the concave surface structure, the light can be reflected to other surfaces of itself, and the number of reflections is further increased, thereby enhancing the light-uniformizing effect of the emergent light. In addition, the first light reflecting structure 103 and the second light reflecting structure 104 are arranged to be circular structures, when light is emitted to an external space, the formed light is circular, and when equipment such as a camera is arranged in the middle of the circular structures, the uniformity of light supplement can be improved.

Referring to fig. 4, fig. 4 is a schematic cross-sectional structure view of another dodging assembly according to an embodiment of the present invention, in other embodiments, the first light reflecting structure 103 may also be a solid structure, that is, the first light reflecting structure 103 does not have a hollow structure, and specifically, the first light reflecting structure 103 with different shapes may be disposed according to the user's liking and requirements.

Referring to fig. 1-4, in some embodiments, the first light reflecting structure 103 and the second light reflecting structure 104 each have a central axis, and the central axis of the first light reflecting structure 103 and the central axis of the second light reflecting structure 104 may coincide. That is to say, first light reflecting structure 103 and second light reflecting structure 104 are concentric structure, so, make the logical light zone 10 that forms be the even ring of size, thereby also be the even ring shape of size via leading to the facula shape in light zone 10 outgoing to the external world, not only can increase pleasing to the eye degree, improve the interactivity of light, when being applied to the light filling scene, can also improve the homogeneity of light filling, thereby further improve the even light effect of even light subassembly.

It is understood that in other embodiments, the central axes of the first light reflecting structure 103 and the second light reflecting structure 104 may not coincide, i.e., the first light reflecting structure 103 and the second light reflecting structure 104 may be eccentric structures. Since the light emitted from the light source 102 is reflected by the first reflective surface 1 and the second reflective surface 2 for multiple times, overlapping and uniformly dispersed light is formed, so that the light emitted to the outside has higher uniformity, and therefore, even if the first reflective structure 103 and the second reflective structure 104 are eccentric structures, the uniformity of the light spot emitted to the outside cannot be affected. That is to say, the utility model provides an even light subassembly makes the tolerance rate between first reflection of light face 1 and the second reflection of light face 2 high to can improve the process window of actually preparing even light subassembly, improve production efficiency.

In some embodiments, the height dimension of the first light reflecting structure 103 is the same as the height dimension of the second light reflecting structure 104, so that the reflection times of the emergent light of the light source 102 on the first light reflecting surface 1 and the second light reflecting surface 2 are the same or close. When the height dimensions of the first light reflecting structure 103 and the second light reflecting structure 104 are larger, the number of times of reflection of the light on the first light reflecting surface 1 and the second light reflecting surface 2 is larger, and specifically, the specific height dimensions of the first light reflecting structure 103 and the second light reflecting structure 104 may be set based on the number of times of reflection of the light on the first light reflecting surface 1 and the second light reflecting surface 2.

The distance between the first light reflecting structure 103 and the second light reflecting structure 104 is related to the diameter size of the first light reflecting structure 103 and the second light reflecting structure 104. When the distance between the first light reflecting structure 103 and the second light reflecting structure 104 is larger, the size of the formed light passing region 10 is larger, and thus, the light spot emitted to the outside through the light passing region 10 will be larger. The specific diameter size that can actually set up first reflection of light structure 103 and second reflection of light structure 104 according to user's actual demand specifically, the utility model discloses do not specifically limit.

Fig. 5 is a schematic sectional structure view of another dodging module according to an embodiment of the present invention, fig. 6 is a schematic sectional structure view of another dodging module according to an embodiment of the present invention, and fig. 7 is a schematic sectional structure view of another dodging module according to an embodiment of the present invention.

Referring to fig. 2, 5, 6 and 7, in some embodiments, a first included angle i between a tangent plane of any point of the first light reflecting surface 1 and a normal of the surface of the lamp socket 101 is: 0-60 degrees, and a second included angle II between the tangent plane of any point in the second reflecting surface 2 and the normal line of the surface of the lamp holder 101 is as follows: 0 to 60 degrees. Referring to fig. 5, when the first included angle i and the second included angle ii are both 0 °, the first reflective surface 1 and the second reflective surface 2 are perpendicular to the surface of the lamp socket 101, and the size of the light-passing region 10 is unchanged in a direction pointing to the bottom of the first reflective structure 103 along the top of the first reflective structure 103. Referring to fig. 2, 6 and 7, when the first included angle i and the second included angle ii are larger than 0 °, the tangent plane of any point of the first light reflecting surface 1 and the tangent plane of any point of the second light reflecting surface 2 are both inclined with respect to the normal of the surface of the lamp socket 101. The shape of the formed light-passing region 10 can be changed by changing the size of the first included angle i and the second included angle ii, for example, the size of the opening of the formed light-passing region 10 can be changed, so as to change the brightness and the size of the light spot emitted into the external space.

Specifically, the direction from the first light reflecting surface 1 to the second light reflecting surface 2 is the first direction X, the direction from the second light reflecting surface 2 to the first light reflecting surface 1 is the second direction Y, the tangent plane of any point in the first light reflecting surface 1 is the first tangent plane, and the tangent plane of any point in the second light reflecting surface 2 is the second tangent plane. The first tangential plane and the second tangential plane may be inclined to 60 ° in the first direction X or 60 ° in the second direction Y with respect to a normal of the surface of the lamp socket 101.

When the first cut surface and the second cut surface are both inclined towards the first direction X or the second direction Y, and the inclination angles are the same, the width dimension of the light-transmitting area 10 is unchanged in the direction pointing to the bottom of the first light-reflecting structure 103 along the top of the first light-reflecting structure 103. Referring to fig. 6, for example, when the first cut surface and the second cut surface are inclined towards the first direction, referring to fig. 6, when the first cut surface and the second cut surface are inclined towards the first direction X, the distance between the openings of the light-transmitting regions 10 is increased compared with the central axis of the first light-reflecting structure 103, so that after the light passing through the light-transmitting regions 10 is emitted to the outside, the formed circle of the light spot is enlarged.

Correspondingly, when the first tangent plane and the second tangent plane are both inclined towards the second direction Y, the distance between the openings of the light-transmitting regions 10 is reduced compared with the central axis of the first light-reflecting structure 103, so that after the light rays passing through the light-transmitting regions 10 are emitted to the outside, the formed circle of the light spots is reduced.

Referring to fig. 2, when the first tangential plane is inclined toward the first direction X and the second tangential plane is inclined toward the second direction Y, the distance between the top of the first light reflecting surface 1 and the top of the second light reflecting surface 2 becomes smaller than the distance between the bottom of the first light reflecting surface 1 and the bottom of the second light reflecting surface 2, so that the size of the opening of the light passing region 10 becomes smaller than the size of the bottom of the light passing region 10. Therefore, when light reaches the top of the light-transmitting area 10 from the bottom of the light-transmitting area 10, the light can generate a gathering effect at the top of the light-transmitting area 10, so that the brightness of a light spot emitted to the outside is increased, and the width of the light spot is reduced.

Referring to fig. 7, when the first tangential plane is inclined toward the second direction Y and the second tangential plane is inclined toward the first direction X, the distance between the top of the first light reflecting surface 1 and the top of the second light reflecting surface 2 becomes larger than the distance between the bottom of the first light reflecting surface 1 and the bottom of the second light reflecting surface 2, so that the size of the opening of the light passing region 10 becomes larger than the size of the bottom of the light passing region 10. Thus, when light reaches the top of the light-transmitting area 10 from the bottom of the light-transmitting area 10, the light can generate a divergence effect at the top of the light-transmitting area 10, so that the brightness of the light spot emitted to the outside is reduced, and the degree of the light-transmitting area 10 is increased.

In addition, the light emitted from the light source 102 has a certain divergence angle, for example, 0 ° to 60 °. Therefore, the included angle between the surface normal of the lamp holder 101 and the surface normal of the first tangent plane and the second tangent plane is set to be 0-60 degrees, so that the light emitted by the light source 102 can be emitted to the first reflecting surface 1 and the second reflecting surface 2, the light emitted to the outside is made to be reflected for multiple times by the first reflecting surface 1 and the second reflecting surface 2, and the light uniformizing effect is improved.

It is understood that, in some embodiments, the first light reflecting surface and the second light reflecting surface may be single curved surfaces, that is, the first light reflecting surface and the second light reflecting surface are formed by one straight line segment rotating around the central axis; in other embodiments, the first light reflecting surface and the second light reflecting surface may also be hyperboloids, that is, the first light reflecting surface and the second light reflecting surface are formed by rotating an arc segment around the central axis for one circle. The utility model discloses do not specifically prescribe a limit to the shape of first reflection of light face and second reflection of light face, only need satisfy in the first reflection of light face 1 tangent plane of arbitrary point and the first contained angle I between the normal on lamp stand 101 surface and be: 0-60 degrees, and a second included angle II between the tangent plane of any point in the second reflecting surface 2 and the normal line of the surface of the lamp holder 101 is as follows: 0-60 degrees.

In some embodiments, further comprising: the first reflective film is arranged on one side, facing the second reflective structure 104, of the first reflective structure 103 and serves as a first reflective surface 1, the second reflective film is arranged on one side, facing the first reflective structure 103, of the second reflective structure 104 and serves as a second reflective surface 2, and the reflectivity of the first reflective film is the same as that of the second reflective film. The arrangement of the first reflective film and the second reflective film can improve the light reflection rate of light on the first reflective surface and the second reflective surface. In some embodiments, the first reflective film and the second reflective film are high-efficiency reflective films, where high efficiency means that the reflectivity of light is more than 85%, so that light loss can be reduced, and more light can be emitted to the outside after being reflected for multiple times. Specifically, in some embodiments, the material of the first reflective film and the second reflective film may be PET films, and the surface of the PET films is plated with a metal material with high reflective performance, such as aluminum.

With reference to fig. 2, the light uniformizing sheet 105 covers the opening of the light passing area 10, specifically, the light uniformizing sheet 105 may be located at the tops of the first light reflecting structure 103 and the second light reflecting structure 104, or may be located between the first light reflecting structure 103 and the second light reflecting structure 104, where the specific installation structure of the light uniformizing sheet 105 is not limited, and only the light uniformizing sheet 105 needs to cover the opening of the light passing area 10, so that the light emitted by the light source 102 passes through the light passing area 10 and then passes through the light uniformizing sheet 105. The dodging sheet 105 functions to perform secondary dodging of light passing through the light-transmitting area 10, and also functions to shield the non-light-emitting light source 102 to beautify the light. Specifically, the principle of the light homogenizing sheet 105 for homogenizing the light is as follows: when the light passes through the light homogenizing sheet 105, many refraction, reflection and scattering phenomena occur, and these refraction, reflection and scattering phenomena can correct the light to achieve the effect of optical diffusion. After being diffused by the light uniformizing sheet 105, the light can become the secondary light source 102 with larger area, better uniformity and stable chromaticity. Specifically, in some embodiments, the light uniformizer 105 may employ a transparent substrate, such as a PET material, and coat both sides of the PET material with optical light scattering particles. In some embodiments, the light homogenizing sheet 105 may have an annular structure or a circular structure, and only the opening position of the light homogenizing sheet 105 covering the light passing region 10 needs to be satisfied.

The light uniformizer 105 may further uniformize the light passing through the light transmitting area 10, when the light source 102 emits the light, the light passes through the light uniformizer 105, and the color of the light uniformizer 105 is related to the color of the light source 102. For example, when the light source 102 is an RGB three-color LED lamp arranged at intervals, the color presented by the light-homogenizing sheet 105 is the color of the RGB three-color LED lamp. Therefore, the color of the light homogenizing sheet 105 can be adjusted by changing the color of the RGB three-color LED lamp, so that the light homogenizing assembly has better interactivity. Based on this point, can be with the utility model provides a dodging subassembly is applied to pass gate class equipment, through the colour of adjusting even light piece 105 and appearing, represents different signals, for example the colour that appears through adjusting even light piece 105 is red, shows to forbid current, and the colour that appears through adjusting even light piece 105 is green, shows to allow current.

In some embodiments, further comprising: the protection sheet is arranged on the surface of one side, away from the lamp holder 101, of the light uniformizing sheet 105, the protection sheet covers the light uniformizing sheet 105, and the protection sheet corresponding to the light transmission area 10 is of a light transmission structure. Because even light piece 105 adopts the PET material more, the rigidity of PET material is relatively poor, consequently, set up the protection piece and protect even light piece 105, can prevent even light piece 105 surface damage to keep the even light effect of even light subassembly and the life of extension even light subassembly. The protection sheet 106 corresponding to the light-transmitting area 10 is a light-transmitting structure, so that the protection sheet does not block the light passing through the light-transmitting area 10 and the light-homogenizing sheet 105. Specifically, in some embodiments, the material of the protection sheet may be glass, and the glass has a greater hardness and a greater transparency, so as to achieve a protection effect without affecting the transmission of light.

Because through multiple reflection, the emergent light of light source 102 will form overlap and evenly dispersed light in passing through light zone 10 to make the light of outgoing to the external world have higher homogeneity, in addition, still set up even light piece 105 and cover the opening that passes through light zone 10, make the light that passes through light zone 10 carry out further dodging by even light piece 105, thereby strengthen even light effect.

Correspondingly, the utility model also provides a lamp assembly, including the dodging subassembly that the above-mentioned embodiment provided, refer to fig. 2, the lamp stand 101 surface that light passing area 10 is just right is provided with a plurality of light sources 102 that the interval set up. In some embodiments, the light source 102 may be an LED lamp, for example, an RGB three-color LED lamp or a white light lamp. Specifically, in some embodiments, the light source 102 may be RGB three-color LED lamps arranged at intervals; in other embodiments, the light source 102 may also be an RGB three-color LED lamp and a white light lamp which are arranged at intervals; in still other embodiments, the white light lamps may be arranged at intervals to satisfy a scene requiring only high-intensity white light for light supplement. Can adjust light efficiency colour temperature and light intensity through the RGB three-colour LED lamp that chooses different colours for use, perhaps adopt the combination of RGB three-colour LED lamp and white light lamp, be applicable to different light filling demands.

Specifically, the light emitted by the light source 102 has a higher uniformity of illuminance after passing through the light distribution area 10 and the light homogenizing sheet 105, so that the light-compensating effect is better, and the light-compensating device is suitable for light compensation of live broadcast equipment and different scenes.

Because can be through the colour that changes RGB three-colour LED lamp to adjust the colour that even light piece 105 presents, make lamps and lanterns subassembly have better interactivity, based on this, can be applicable to customs gate class equipment, through the colour of adjusting even light piece 105 presentation, represent different signals.

In addition, can also combine the better light supplementation effect of lamps and lanterns subassembly and interactive performance, be applied to the payment class equipment of brushing the face, sweeping the sign indicating number, brushing the palm with the lamps and lanterns subassembly to both can carry out the light filling to brushing the face, sweeping equipment such as sign indicating number, brushing the palm, raise the efficiency, can improve human-computer interaction performance again.

In the lamps and lanterns subassembly that this embodiment provided, when a plurality of LED lamps interval were arranged, after the light of LED lamp outgoing was reflected by first reflection of light face 1 and 2 times of second reflection of light face, the light of a plurality of LED lamps will be by homodisperse to make the light intensity highly uniform of light of outgoing to external space, improve lamps and lanterns subassembly outgoing light's homogeneity.
