DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0031] The technical solutions in the implementation scheme of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the implementation scheme of the utility model.

[0032] See also Figure 1The embodiment of the utility model proposes a light source system 10, which includes a light source assembly 100 and a polarizing structure 200. The light source assembly 100 may include a plurality of light sources 110 and a plurality of condensing lenses 120. The plurality of light sources 110 may correspond to the plurality of condensing lenses 120 respectively. The light source 110 may be used to output light, and the condensing lenses 120 may be used to receive and condense the light outputted by the corresponding light source 110. The polarizing structure 200 may emit the light beams condensed by the plurality of condensing lenses 120 in a plurality of directions, so as to partition the light spot of the light source system 10. Thus, compared with the light source system in the related art, the light source system 10 of the present application uses the polarizing structure 200 to emit the light beams condensed by the plurality of condensing lenses 120 in a plurality of directions, so as to partition the light spot of the light source system 10, thereby meeting the use requirements of the user.

[0033] In addition, since the polarizing structure 200 can process the light beams output by multiple focusing lenses 120 at the same time, the polarizing structure 200 and the multiple focusing lenses 120 can be matched more compactly, thereby making the structure of the light source system 10 more compact, and further making the volume of the light source system 10 more compact.

[0034] It is understandable that the polarizing structure 200 can emit the light beams focused by the multiple focusing lenses 120 in multiple directions, that is, the polarizing structure 200 can emit most of the light beams focused by the multiple focusing lenses 120 in multiple directions. The multiple directions include at least two different directions.

[0035] The polarizing structure 200 may be a polarizing lens, and the polarizing lens may have an incident surface (not numbered in the figure) and an exit surface 201 that are arranged opposite to each other, and the light beam focused by the condenser lens 120 may sequentially pass through the incident surface and the exit surface 201 of the polarizing structure 200. The incident surface may be substantially perpendicular to the optical axis of the light beam focused by the condenser lens 120, so that the light beam focused by the condenser lens 120 is vertically incident to the incident surface, thereby facilitating the polarizing structure 200 to adjust the direction of the light beam passing through the polarizing structure 200 through the angle α between the exit surface 201 and the optical axis of the light beam focused by the condenser lens 120.

[0036] In some embodiments, the polarizing structure 200 may have multiple exit surfaces 201 , which may be arranged in sequence along the length direction of the light source system 10 , so that the multiple exit surfaces 201 may be arranged neatly and orderly, thereby making the structure of the light source system 10 more compact.

[0037] The multiple exit surfaces 201 may correspond to the multiple condensing lenses 120 respectively, and the multiple exit surfaces 201 face different directions respectively. Specifically, the multiple exit surfaces 201 correspond to the condensing lenses 120 one by one, and when the light emitted by the light source assembly 100 is condensed by the condensing lenses 120 respectively, the multiple condensed light beams will be guided to different directions by the multiple exit surfaces 201 of the polarization structure 200, so as to facilitate the light source system 10 to form clear light spot partitions.

[0038] It can be understood that the larger the angle α formed by the exit surface 201 and the optical axis of the light beam after being focused by the corresponding focusing lens 120, the steeper the exit surface 201, the larger the slope of the exit surface 201, the larger the angle formed by the light beam passing through the exit surface 201 and the optical axis of the light beam after being focused by the corresponding focusing lens 120, that is, the larger the polarization angle.

[0039] See also Figures 1 to 4 , Figure 4 The left picture is a color effect picture of the light spot of the light source system 10. Figure 4 The right picture is a black and white effect picture of the light spot of the light source system 10, forming Figure 4 The receiving surface of the spot effect is perpendicular to the length direction of the light source system 10. In some embodiments, the angle α formed by the multiple exit surfaces 201 and the optical axis of the light beam after the corresponding condenser lens 120 is gradually increased or decreased along the length direction of the light source system 10. Specifically, the multiple exit surfaces 201 are increasingly steeper or more gentle along the length direction of the light source system 10. Each exit surface 201 can be designed to form a specific angle with the optical axis of the light beam of the corresponding condenser lens 120. The size of this angle can be designed as needed to achieve the desired spot distribution and lighting effect. In this way, since the angle α formed by the multiple exit surfaces 201 and the optical axis of the light beam after the corresponding condenser lens 120 is gradually increased or decreased along the length direction of the light source system 10, the projection angle and distribution range of the exit light of the light source system 10 will also be different, thereby helping the light source system 10 to form multiple spot partitions along the axial direction of the optical axis of the light beam after the condenser lens 120 is focused, so as to achieve unique spot partition characteristics and lighting effects.

[0040] See also Figures 5 to 8 , Figure 8 The left picture is a color effect picture of the light spot of the light source system 10. Figure 8 The right picture is a black and white effect picture of the light spot of the light source system 10, forming Figure 8The receiving surface of the spot effect is parallel to the length direction of the light source system 10 and perpendicular to the width direction of the light source system 10. In some embodiments, the angle α formed by the multiple exit surfaces 201 and the optical axis of the light beam after focusing by the corresponding focusing lens 120 first decreases and then increases along the length direction of the light source system 10. Specifically, each exit surface 201 can be designed to form a specific angle with the optical axis of the light beam of the corresponding focusing lens 120. The size of this angle can be designed as needed to achieve the desired spot distribution and lighting effect. In this way, since the angle α formed by the multiple exit surfaces 201 and the optical axis of the light beam after focusing by the corresponding focusing lens 120 along the length direction of the light source system 10 first decreases and then increases, the projection angle and distribution range of the exit light of the light source system 10 will also be different, thereby helping the light source system 10 to form multiple spot partitions along the length direction of the light source system 10 to achieve unique spot partition characteristics and lighting effects.

[0041] In some embodiments, the polarizing structure 200 may include a first polarizing unit 210, a second polarizing unit 220, and a third polarizing unit 230. The first polarizing unit 210, the second polarizing unit 220, and the third polarizing unit 230 are sequentially arranged along the length direction of the light source system 10. The exit surface 201 of the first polarizing unit 210 faces the third polarizing unit 230. The exit surface 201 of the second polarizing unit 220 is perpendicular to the optical axis of the light beam after being focused by the focusing lens 120. The exit surface 201 of the third polarizing unit 230 faces the first polarizing unit 210. The light beam passing through the first polarizing unit 210 is polarized in a direction away from the third polarizing unit 230, the light beam passing through the second polarizing unit 220 is emitted along the axial direction of the optical axis of the light beam after being focused by the focusing lens 120, and the light beam passing through the third polarizing unit 230 is polarized in a direction away from the first polarizing unit 210, thereby facilitating the light source system 10 to form a plurality of light spot partitions along the length direction of the light source system 10.

[0042] See also Figures 9 to 11 , Fig.11 The left picture is a color effect picture of the light spot of the light source system 10. Fig.11 The right picture is a black and white effect picture of the light spot of the light source system 10, forming Fig.11 The receiving surface of the light spot effect is parallel to the length direction of the light source system 10 and perpendicular to the width direction of the light source system 10. In some embodiments, the polarizing structure 200 is a convex lens, and the exit surface 201 of the polarizing structure 200 can be set in a hemispherical shape. Specifically, the overall shape of the polarizing structure 200 can be roughly set in a hemispherical shape, and the axial direction of the polarizing structure 200 is roughly parallel to the axial direction of the optical axis of the light beam after focusing by the focusing lens 120, thereby helping the light source system 10 to project the effect of light spot partitioning along the length direction of the light source system 10.

[0043] The polarizing structure 200 may include a first polarizing portion 210, a second polarizing portion 220 and a third polarizing portion 230. The first polarizing portion 210, the second polarizing portion 220 and the third polarizing portion 230 are arranged in sequence along the radial direction of the polarizing structure 200. The second polarizing portion 220 is connected between the first polarizing portion 210 and the third polarizing portion 230. The exit surface 201 of the first polarizing portion 210 and the exit surface 201 of the third polarizing portion 230 are arranged opposite to each other. The second polarizing portion 220 may be located in the middle of the polarizing structure 200. The axial direction of the second polarizing portion 220 is roughly parallel to the axial direction of the optical axis of the light beam after focusing by the focusing lens 120. In this way, the light beam passing through the second polarizing portion 220 is emitted along the axial direction of the optical axis of the light beam after being focused by the focusing lens 120, the light beam passing through the first polarizing portion 210 is polarized toward the third polarizing portion 230, and the light beam passing through the third polarizing portion 230 is polarized toward the second polarizing portion 220, thereby helping to achieve the effect of projecting a light spot partition along the length direction of the light source system 10.

[0044] In some embodiments, the light source 110 can be a multi-color lamp bead, which is a light-emitting element that can emit light of multiple colors. The multi-color lamp bead can include multiple light-emitting chips of different colors. For example, it can be packaged with light-emitting chips of three colors: red, green, and blue. These chips are packaged in the same lamp bead. Each light-emitting chip can emit light of a specific color, which helps the light source system 10 to achieve mixing and changing of multiple colors by adjusting the brightness of light-emitting chips of different colors, thereby enriching the color expression capability of the light source system 10.

[0045] The multiple light sources 110 can be controlled independently. Specifically, the user can adjust the light state of each light source 110 individually according to the needs of the light spot partitioning to achieve more precise lighting control. For example, in the light spot area where the focus needs to be highlighted, the brightness of the corresponding light source 110 can be increased or its color can be changed; and in the light spot area where the light intensity needs to be reduced, the brightness of the corresponding light source 110 can be reduced, so that the light source system 10 can adapt to a variety of different lighting needs and scenes.

[0046] In some embodiments, the light source assembly 100 may further include a plurality of light mixing covers 300, which may be milky white, and the plurality of light mixing covers 300 may be respectively covered on the corresponding light sources 110, and the outgoing light of the light source 110 passes through the corresponding light mixing cover 300, the corresponding focusing lens 120 and the polarizing structure 200 in sequence. In this way, when the light source 110 emits light, the light first enters the corresponding light mixing cover 300. Inside the light mixing cover 300, the light will undergo optical phenomena such as reflection, refraction and scattering, so that light of different colors can be fully mixed, and the mixed light will be uniformly emitted from the light mixing cover 300, thereby enabling the light source system 10 to achieve a more uniform and natural color mixing effect. This design not only improves the lighting quality, but also enables the light source system 10 to adapt to more scenes that require rich color performance. For example, in stage lighting, by adjusting the color and brightness of different light sources 110 and then mixing them with the light mixing cover 300, various complex lighting effects and color changes can be achieved.

[0047] In some embodiments, the light source system 10 may further include a mounting bracket, and the polarizing structure 200 may be detachably mounted on the mounting bracket. Specifically, the polarizing structure 200 may be fixed to the mounting bracket by plugging; or, the polarizing structure 200 may be fixed to the mounting bracket by fasteners, thereby facilitating the polarizing structure 200 to be detachably mounted on the mounting bracket. In this way, the user may adjust the position of the polarizing structure 200 according to the installation direction of the light source system 10, thereby facilitating the projection direction of the light source system 10 to meet the user's usage requirements. In addition, since the polarizing structure 200 is detachably mounted on the mounting bracket, the user may change the polarization direction by adjusting the direction of the polarizing structure 200, thereby satisfying the use of the light source system 10 in different installation directions. Moreover, the user may also achieve different light spot partitioning effects of the light source system 10 by replacing different polarizing structures 200.

[0048] In some embodiments, the light source system 10 may further include a driver (not shown), which is drivably connected to the polarizing structure 200 to drive the polarizing structure 200 to rotate. The driver may be a motor, a stepping motor, a servo motor or other types of rotary drive devices, and the output shaft of the driver may be drivably connected to the polarizing structure 200 to drive the polarizing structure 200 to rotate. In other embodiments, a driving gear is installed on the output shaft of the driver, and a driven gear is installed on the polarizing structure 200 or its support shaft, and rotation transmission is achieved through gear meshing. In addition, other suitable transmission methods such as belt drive and chain drive can also be used. In this way, the light source system 10 can realize the rotation of the polarizing structure 200 through the driver, so that the light source system 10 adjusts the irradiation direction and range of the light to meet the lighting requirements in different scenes. In addition, the light source system 10 can achieve dynamic lighting effects, enhance spatial hierarchy and visual impact.

[0049] In some embodiments, there are multiple options for the focusing lens 120 , for example, the focusing lens 120 may be a TIR lens, a convex lens, or a window lamp lens.

[0050] In some embodiments, the light source system 10 may further include a circuit board 400 , and the circuit board 400 may be electrically connected to the plurality of light sources 10 , thereby facilitating the light source system 10 to independently control the plurality of light sources 110 to operate.

[0051] An embodiment of the utility model provides a lamp, which may include a shell and a light source system 10. The light source system 10 may be installed in the shell. For example, the light source system 10 may be installed in the shell, so that the shell can protect the light source system 10. For another example, the light source system 10 may be installed on the shell, so that the shell can support and install the light source system 10.

[0052] The specific structure of the light source system 10 can refer to the above embodiments. Since the lamp adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.
