Description

Technical Field

[0001] This application relates to the field of lighting technology, and more particularly to a lighting assembly and terminal. Background Technology

[0002] Vehicles and other terminals are typically equipped with lighting assemblies for illumination or projection. A lighting assembly usually includes a light source module, a housing, a decorative ring, and a mask, all of which are connected to the housing.

[0003] During normal driving, the main optical axis of the light source module is parallel to the reference plane, and the beam emitted is used for low beam or high beam illumination. In environments such as garages or where projection is required, the light source module can be rotated so that the main optical axis tilts downward. In this case, the beam emitted by the light source module can be projected onto the reference plane for near-ground illumination, or a specific image can be projected onto the ground. The projected content can be a startup animation, weather forecast, or terminal status prompts, etc.

[0004] However, in current lighting assemblies, when the beam of light from the light source module is projected onto the reference surface, some of the light will hit the corners or decorative rings of the mask. After being reflected and refracted by the corners or decorative rings of the mask, this light will cause stray light from the beam of light source module, which will then cause problems such as glare and blurred projected images. Utility Model Content

[0005] This application provides a lighting assembly and terminal that can prevent the light from the light source module from being reflected and / or refracted by the corners and decorative rings of the mask, prevent stray light from the light beam of the light source module, avoid glare, and prevent the projected image from becoming blurry.

[0006] This application provides a lighting assembly, including: a housing, a light source module, a shielding plate, and a housing structure member. The housing structure member is connected to the housing, and the housing and the housing structure member enclose a receiving cavity. The light source module and the shielding plate are both disposed within the receiving cavity. The light source module is used to emit a light beam, and the light source module can be a pixel light source module, such as LED, micro-LED, or DLP.

[0007] The light source module includes a first mode, which is used when the lighting assembly is applied to a vehicle and the vehicle needs near-ground lighting in environments such as garages, or when it needs to project an image onto a reference surface. The reference surface can be the ground.

[0008] In the first mode, the main optical axis of the light source module is tilted downward. At this time, the light beam of the light source module can be directed to the ground closer to the vehicle. The shield blocks part of the light outlet of the light source module to block part of the light beam directed by the light source module towards the housing structure.

[0009] In the first mode, because the light beam shines downwards, some of the light will reach the housing structure. The housing structure will reflect or refract a portion of this light, which will cause the projected image to be blurry and is also prone to glare. In this application, in the first mode, a shield is used to block part of the light outlet to prevent the light that may be refracted or reflected from reaching the housing structure. This can filter out stray light, prevent stray light from affecting the projected image, improve the clarity of the projected image, and avoid glare.

[0010] In some possible implementations, the light source module also includes a second mode. During vehicle operation, the light source module is in the second mode, in which it has both low beam and high beam states. In the second mode, the main optical axis of the light source module is parallel to the reference plane. At this time, the baffle does not block the light output port of the light source module, and the light source module can provide illumination for the user during driving.

[0011] In some possible implementations, the housing structure may include a face mask and / or a decorative ring. The face mask is light-transmitting and has corner portions. The light outlet of the light source module faces the face mask, and the decorative ring is connected to the housing and surrounds the light source module. When the optical module is in the first mode, some light rays will hit the corner portions of the face mask and / or the decorative ring. The decorative ring will reflect the light, and the corner portions of the face mask will refract the light.

[0012] In some possible implementations, the housing structure includes a mask, and in a first mode, a shield blocks a portion of the light outlet to block the light beam from the light source module directed at the corner.

[0013] In the above implementation method, the shield can prevent light from hitting the corner of the mask, prevent the light refracted at the corner from affecting the clarity of the projected image, and prevent glare problems.

[0014] In some possible implementations, the housing structure includes a decorative ring that is attached to the housing and surrounds the light source module.

[0015] In the above implementation method, the shield can prevent light from hitting the decorative ring, prevent the light reflected from the decorative ring from affecting the clarity of the projected image, and avoid glare problems.

[0016] In some possible implementations, in the first mode, the area of ​​the light-emitting port blocked by the baffle is between 1 / 20 and 3 / 4 of the total area of ​​the light-emitting port.

[0017] In the above implementation method, the proportion of the area where the light outlet is blocked is set to the above range, which can prevent light from hitting the housing structure and also does not affect the brightness of the projected image.

[0018] In some possible implementations, in the first mode, the angle between the shield and the main optical axis of the light source module is between 45 degrees and 135 degrees.

[0019] In the above implementation, if the angle between the shielding plate and the main optical axis of the light source module is less than 45 degrees or greater than 145 degrees, the surface area of ​​the shielding plate facing the light source module needs to be very large to achieve a shielding effect. This results in a large shielding plate volume, which in turn leads to a large space occupation and is not conducive to space saving. When the angle between the shielding plate and the main optical axis of the light source module is within the range of 45 degrees to 135 degrees, the shielding plate can effectively shield the light source, and the shielding plate volume is small, occupying less space and saving space.

[0020] In some possible implementations, the luminaire assembly also includes a drive module connected to a baffle plate. The drive module drives the baffle plate to move so that the baffle plate blocks a portion of the light outlet.

[0021] In the above implementation method, by setting up a driver module to achieve automated operation, the convenience of using the first mode of the light source module can be increased.

[0022] In some possible implementations, the drive module includes a drive component and a transmission component. The drive component is connected to the housing or the light source module. One side of the transmission component is connected to the output end of the drive component, and the other side of the transmission component is connected to the shield. The drive component drives the shield to move through the transmission component so that the shield blocks part of the light outlet.

[0023] In the above implementation, by setting up a driving component and a transmission component, the shield can smoothly switch between blocking and not blocking the light output port. When the light source module is in the second mode, the shield does not block the light output port. When the light source module switches from the second mode to the first mode, the driving component is activated to drive the transmission component to move. The transmission component then drives the shield to move so that the shield partially blocks the light output port. When the light source module returns from the first mode to the second mode, the driving component, through the transmission component, drives the shield to move to a position where it does not block the light output port.

[0024] In some possible implementations, the driver is also used to drive the light source module to switch between the second mode and the first mode.

[0025] In the above implementation, the light source module and the shield share a single driver, which can reduce the number of parts in the lamp assembly.

[0026] In some possible implementations, the luminaire assembly may include two drivers, namely a first driver and a second driver. The first driver is used to drive the movement of the baffle, and the second driver is used to drive the light source module to switch between a second mode and a first mode.

[0027] In some possible implementations, the driving component includes a motor, a cylinder or a hydraulic cylinder, and the transmission component includes one of a gear mechanism, a connecting rod, a lead screw mechanism, a cam mechanism and a worm gear mechanism.

[0028] In the above implementation methods, designers can select the corresponding drive components and transmission components according to actual needs, offering a wide range of choices and high flexibility.

[0029] In some possible implementations, the driving component drives the baffle to rotate or move in a preset direction via the transmission component. The preset direction includes a first direction or a second direction. The first direction is perpendicular to the main optical axis of the light source module; the second direction is perpendicular to the main optical axis of the light source module and perpendicular to the first direction.

[0030] In the above implementation methods, the movement of the shield can include rotation, movement along a first direction, or movement along a second direction. Designers can choose the movement method of the shield according to the space of the lamp assembly, which offers a wide range of choices and high flexibility.

[0031] In some possible implementations, the shielding plate includes a first shielding plate and a second shielding plate, which are located on both sides of the light outlet. In a first mode, the first shielding plate and the second shielding plate move to block a portion of the light outlet.

[0032] In the above implementation method, compared with the integral shield, the shield is divided into a smaller first shield and a second shield, which facilitates flexible layout and increases design flexibility. In addition, when the light source module is in the first mode, the first shield and the second shield can move synchronously to block part of the light outlet, which can quickly filter stray light.

[0033] In some possible implementations, the baffle includes multiple louvers. In a first mode, the angle between the surface of the multiple louvers and the main optical axis of the light source module is greater than or equal to a first angle, and the distance between any two adjacent louvers is less than or equal to a first distance, so as to block part of the light outlet.

[0034] The light source module also includes a second mode. In the second mode, the main optical axis of the light source module is parallel to the reference plane, and the shield does not block the light outlet of the light source module. In the second mode, the angle between the surface of the multiple louvers and the main optical axis of the light source module is less than or equal to the second angle, the distance between any two adjacent louvers is greater than or equal to the second distance, and the light beam of the light source module can pass through the gap between any two adjacent louvers.

[0035] The first distance is less than the second distance, and the first included angle is greater than the second included angle.

[0036] In the above implementation, the small size of a single louver allows for flexible layout and increases design flexibility. Furthermore, multiple louvers can move synchronously to quickly block the light outlet, improving the efficiency of filtering stray light and resulting in a fast and clear projected image. The louvers can also flexibly adjust their light transmission; they can be adjusted according to the clarity of the projected image, ensuring that the louvers block stray light without affecting the brightness of the projected image.

[0037] In some possible implementations, the baffle includes multiple louvers. In a second mode, the surfaces of the louvers are parallel to the main optical axis of the light source module, and there is a gap between any two adjacent louvers, allowing the light beam from the light source module to pass through the gap between any two adjacent louvers. In this mode, the baffle has minimal impact on the light beam. In a first mode, the surfaces of the louvers are perpendicular to the main optical axis of the light source module, and any two adjacent louvers are in contact to block part of the light outlet. In this mode, no light is exposed between two adjacent louvers, improving the blocking effect and avoiding stray light or glare problems.

[0038] A second aspect of this application provides a terminal, including any of the lighting assemblies in the first aspect of this application.

[0039] Among some possible implementations, the terminal includes one of the following: a vehicle, a robot, and a drone.

[0064] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the lighting assembly 100 provided in the embodiments of this application. Figure 2 for Figure 1 The diagram shows a split structure of the lighting assembly 100. This application provides a lighting assembly 100 that can be applied to terminals such as vehicles to provide illumination and projection. The lighting assembly 100 includes a housing 10, a light source module 20, and a housing structural member 50. Figure 1 and Figure 2The purpose of this illustration is solely to depict the connection relationship between the housing 10, the light source module 20, and the housing structure 50, and is not intended to specifically limit the connection positions, specific structures, or quantities of each device. In other embodiments of this application, the lighting assembly 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0065] The light source module 20 includes a light source, a lens assembly, a control module, and a heat sink. The light source can be a laser light source or a light-emitting diode (LED). The lens assembly can control the light emitted by the light source, such as focusing the light; enhancing illumination intensity; controlling high or low beams to avoid glare; and optimizing light utilization, thereby improving the lighting effect. The control module can receive various signals and control the light source module 20 to turn on, off, switch modes, and monitor for faults based on the received signals. The heat sink dissipates the heat generated by the light source module 20 during operation, ensuring stable operation. The light source module can be a pixel light source module, such as a micro light-emitting diode (micro-LED), LED, or digital light processing (DLP).

[0066] For example, the field of view (FOV) of the light source module 20 is between 4 degrees and 10 degrees vertically, the FOV is between 10 degrees and 30 degrees horizontally, the brightness of the light source module 20 is between 500 lumens (LM) and 1000 LM, and the size of the light outlet 21 of the light source module 20 is between 20 mm and 60 mm.

[0067] The housing 10 is used to support the light source module 20 and the housing structure 50. Exemplarily, the housing 10 can be an opaque plastic part. The housing structure 50 is connected to the housing 10, and the housing structure 50 and the housing 10 together form a receiving cavity 11 for accommodating the light source module 20. Exemplarily, the housing 10 can be a frame-like structure with an opening on one side. The housing 10 can be a regular shape such as a cuboid frame, a cube frame, a cylindrical frame, or an elliptical cylindrical frame, or it can be an irregular shape. The housing structure 50 is connected to the opening of the housing 10, such that the housing 10 and the housing structure 50 together form the receiving cavity 11.

[0068] For example, the housing structure 50 includes a decorative ring 30 and a face shield 40.

[0069] The decorative ring 30 can be made of plastic and is annular in shape. It is connected to the housing 10 and surrounds the light source module 20. For example, one side of the decorative ring 30 is fixed inside the housing 10, and the other side extends outside the housing 10. The decorative ring 30 can be fixed to the inner wall of the receiving cavity 11 by means of clips, slots, screws, or adhesive. The decorative ring 30 can conceal gaps and screws, enhancing the refined appearance of the lighting assembly 100.

[0070] The face mask 40 is translucent and has a corner portion 41, which is often part of the design of the face mask 40. The face mask 40 includes a main body 42 and an extension 43, with the corner portion 41 located on the main body 42. The main body 42 is located on the side of the decorative ring 30 away from the housing 10 to cover the opening of the housing 10. The extension 43 surrounds the outer periphery of the main body 42, wraps around the decorative ring 30, and extends to be fixedly connected to the housing 10, so that the housing 10, the decorative ring 30, and the face mask 40 form a receiving cavity 11. The extension 43 and the housing 10 can be fixedly connected by welding, bonding, or snap-fitting. For example, the face mask 40 can be transparent or semi-transparent, and can be made of polycarbonate or acrylic. The light emission port 21 of the light source module 20 faces the main body 42 of the face mask 40, and the light beam emitted by the light source module 20 is emitted through the light emission port 21 and the face mask 40.

[0071] Alternatively, in some other embodiments, the housing structure 50 may only include the decorative ring 30 or the face shield 40.

[0072] For example, refer to Figure 3 , Figure 3 This is a schematic diagram of the light source module 20 of the lighting assembly 100 provided in this application embodiment, in a first mode. The light source module 20 includes a first mode in which the principal optical axis L of the light source module 20 is tilted downwards. For example, the angle between the principal optical axis L and the reference plane L1 is between 8 and 12 degrees. Optionally, the angle between the principal optical axis L and the reference plane L1 can be 8, 9, 10, 11, or 12 degrees. In this mode, the light source module 20 can illuminate the ground and obstacles nearby (e.g., within 10 meters of a vehicle). For example, when a vehicle enters a space with many obstacles, such as a garage, the first mode can be used for illumination. In the first mode, the light source module 20 can also project images onto the ground, such as text or images. The text could be the current status of the vehicle (e.g., the vehicle is temporarily parked), and the image could be a car logo or a user-favorite animated character.

[0073] In some embodiments, reference is made to Figure 4 , Figure 4This is a schematic diagram of the light source module 20 of the lamp assembly 100 provided in this application embodiment, showing a second mode. The light source module 20 also includes a second mode. When the lamp assembly 100 is in the second mode, the principal optical axis L of the light source module 20 is parallel to the reference plane L1. The reference plane L1 can be the ground. Here, parallelism includes errors. For example, if the angle between the principal optical axis L and the reference plane L1 is between 0 degrees and 5 degrees, it is considered that the principal optical axis L and the reference plane L1 are parallel. When the lamp assembly 100 is in the second mode, it includes a low beam state and a high beam state. In the low beam state, the beam of the light source module 20 can illuminate the road surface, pedestrians, and obstacles nearby (e.g., 30 to 50 meters away from the vehicle), while avoiding the beam directly shining into the eyes of the driver of the oncoming vehicle. In the high beam state, the beam of the light source module 20 can illuminate the road surface, intersections, curves, or obstacles at a distance (e.g., 100 to 150 meters away from the vehicle).

[0074] However, in this embodiment, when the light source module 20 is in the first mode, that is, when the main optical axis L of the light source module 20 is tilted downwards, some light will be emitted to the housing structure 50. The housing structure 50 includes a face mask 40 and / or a decorative ring 30. The corner 41 of the face mask 40 is mostly designed according to the shape of the lamp assembly 100, as shown in the reference. Figure 3 In (a), the corner 41 of the mask 40 may refract this portion of the light, see reference. Figure 3 In (b), the decorative ring 30 may also reflect this part of the light. The reflected and / or refracted light becomes stray light that affects the projected image, causing the projected image to be blurry and glare to occur.

[0075] refer to Figure 5 , Figure 5 This is a schematic diagram of the structure of the lamp assembly 100 provided in this embodiment, with a shield 60. To solve the above problems, the lamp assembly 100 provided in this embodiment further includes a shield 60. When the light source module 20 is in the second mode, the principal optical axis L of the light source module 20 is parallel to the reference plane L1. At this time, the reference... Figure 5 In (a), the shielding plate 60 does not block the light outlet 21 of the light source module 20. When the light source module 20 is in the first mode, the main optical axis L of the light source module 20 is tilted downwards. At this time, the reference... Figure 5 In (b) and (c), the shielding plate 60 blocks a portion of the light outlet 21 of the light source module 20 to block part of the light beam emitted by the light source module 20 towards the housing structure 50.

[0076] For example, the shield 60 is made of an opaque material. The shield 60 can be made of a material with inherent light-blocking properties, such as plastic or metal, or it can be made of a translucent material that can be coated with light-absorbing or reflective materials, such as glass. Light blocking is achieved by coating the surface of the glass with light-absorbing or reflective materials. The shield 60 is a thin plate, and its shape can be a regular shape such as rectangle, triangle, circle, or ellipse, or it can be an irregular shape; this embodiment does not impose any limitations. The two opposing surfaces of the shield 60 along its thickness direction are relatively large flat planes, and one of these two planes serves as a blocking surface, which can block a portion of the light outlet 21.

[0077] For example, since the main optical axis L of the light source module 20 is tilted downward, part of the light rays that hit the housing structure 50 are part of the light rays emitted from the lower side of the light outlet 21 of the light source module 20. Based on this, the shielding plate 60 needs to shield the lower part of the light outlet 21 of the light source module 20, while exposing the upper part of the light outlet 21 of the light source module 20.

[0078] In this embodiment, a shield 60 is used to block a portion of the light outlet 21 of the light source module 20, preventing light from reaching the housing structure 50 and thus preventing the light from being reflected or refracted by the housing structure 50. That is, the shield 60 can prevent light from reaching the corner 41 of the decorative ring 30 and the mask 40, prevent light from being reflected by the decorative ring 30, and prevent light from being refracted by the corner 41 of the mask 40. This can control abnormal light output, ensure the clarity of the image projected onto the reference surface L1, and prevent glare. Furthermore, since the light source module 20 has a lower brightness requirement in the first mode, blocking part of the light will not affect the projection effect of the image, and the light blocked by the shield 60 itself cannot be used normally, so it will not add any extra brightness.

[0079] In some embodiments, the area of ​​the light-emitting port 21 blocked by the baffle plate 60 is between 1 / 20 and 3 / 4 of the total area of ​​the light-emitting port 21. The baffle plate 60 blocks the lower part of the light-emitting port 21 of the light source module 20, and the area of ​​the lower part accounts for between 1 / 20 and 3 / 4 of the total area of ​​the light-emitting port 21. Optionally, this value can be 1 / 20, 1 / 10, 1 / 4, 1 / 2, or 3 / 4, etc. Figure 5 Figure (b) shows that the area blocked by the shield 60 is 1 / 20 of the total area of ​​the light outlet 21. Figure 5(c) shows that the area blocked by the shield 60 is 3 / 4 of the total area of ​​the light outlet 21. The area ratio of the lower part is designed according to the proportion of light that can reach the corner 41 of the decorative ring 30 and the mask 40. As long as light is prevented from reaching the corner 41 of the decorative ring 30 and the mask 40, this application does not impose specific limitations. The proportion of the area of ​​the light outlet 21 that is blocked is set within the above range, which can prevent light from reaching the housing structure 50 and also does not affect the brightness of the projected image.

[0080] In some embodiments, reference is made to Figure 6 , Figure 6 This is a schematic diagram showing the angle between the principal optical axis L of the light source module 20 and the shielding plate 60 in the lamp assembly 100 provided in this application embodiment. The angle between the shielding plate 60 and the principal optical axis L of the light source module 20 ranges from 45 degrees to 135 degrees. Exemplarily, this angle refers to the angle between the shielding surface of the shielding plate 60 and the principal optical axis L of the light source module 20. Optionally, the angle can be 45 degrees (e.g., ...). Figure 6 (as shown in (a)), 50 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees or 135 degrees (as shown in (a)). Figure 6 (As shown in Figure (b)). If the angle between the shielding plate 60 and the principal optical axis L of the light source module 20 is less than 45 degrees or greater than 145 degrees, the shielding plate 60 needs to have a larger volume to achieve the shielding effect, which results in the shielding plate 60 occupying a large amount of space and causing space waste. When the angle between the shielding plate 60 and the principal optical axis L of the light source module 20 is in the range of 45 degrees to 135 degrees, the shielding plate 60 can effectively shield, and the shielding plate 60 has a smaller volume and occupies less space.

[0081] In some embodiments, reference is made to Figure 7 , Figure 7 This is a schematic diagram of a lamp assembly 100 provided in this application embodiment, in which a shield 60 is driven by a drive module 70. The lamp assembly 100 further includes a drive module 70, which includes a drive member 80 and a transmission member 90. The drive member 80 is connected to the housing 10 or the light source module 20. One side of the transmission member 90 is connected to the output end of the drive member 80, and the other side of the transmission member 90 is connected to the shield 60. The drive member 80 drives the shield 60 to move through the transmission member 90, so that the shield 60 blocks a portion of the light outlet 21. Exemplarily, the drive member 80 includes a motor, a cylinder, or a hydraulic cylinder, and the transmission member 90 includes at least one of a gear mechanism, a connecting rod, a lead screw mechanism, a cam mechanism, and a worm gear mechanism.

[0082] By configuring the driving component 80 and the transmission component 90, the shielding plate 60 can smoothly switch between blocking and not blocking the light output port 21. When the light source module 20 is in the second mode, the shielding plate 60 does not block the light output port 21. When the light source module 20 switches from the second mode to the first mode, the driving component 80 is activated to drive the transmission component 90 to move. The transmission component 90 drives the shielding plate 60 to move so that the shielding plate 60 blocks a portion of the light output port 21. When the light source module 20 returns from the first mode to the second mode, the driving component 80 drives the shielding plate 60 to move through the transmission component 90 to a position where the shielding plate 60 does not block the light output port 21.

[0083] In some embodiments, the driver 80 is also used to drive the light source module 20 to switch between a first mode and a second mode. That is, the light source module 20 and the shield 60 share a single driver 80, which can reduce the number of parts in the lamp assembly 100.

[0084] In some other embodiments, the lighting assembly 100 may include two driving elements 80, namely a first driving element 80 and a second driving element 80. The first driving element 80 is used to drive the baffle 60 to move, and the second driving element 80 is used to drive the light source module 20 to switch between a first mode and a second mode.

[0085] In some embodiments, the driving component 80 drives the baffle plate 60 to rotate, move along a first direction, or move along a second direction via the transmission component 90. The first direction is perpendicular to the main optical axis L of the light source module 20; the second direction is perpendicular to the main optical axis L of the light source module 20 and also perpendicular to the first direction. That is, the movement mode of the baffle plate 60 includes rotation, movement along the first direction, or movement along the second direction. Designers can choose the movement mode of the baffle plate 60 according to the space of the lamp assembly 100, providing a wide range of choices and high flexibility.

[0086] Several implementation methods are described below.

[0087] In one possible implementation, refer to Figure 7 The driving component 80 is a rotary motor 82, and the transmission component 90 is a connecting rod 91. The body of the rotary motor 82 is connected to the light source module 20, one end of the connecting rod 91 is connected to the output shaft of the rotary motor 82, and the baffle plate 60 is connected to the other end of the connecting rod 91. (Reference) Figure 7 In (a), when the light source module 20 is in the second mode, the blocking surface of the shielding plate 60 is away from the light outlet 21, and the blocking surface is parallel to the principal optical axis L of the light source module 20. (Reference) Figure 7In step (b), when the light source module 20 switches from the second mode to the first mode, the rotary motor 82 drives the baffle plate 60 to rotate via the connecting rod 91, so that the baffle surface of the baffle plate 60 moves to block part of the light outlet 21 of the light source module 20, preventing light from hitting the housing structure 50. At this time, the baffle surface and the light source module 20 form an angle of approximately 45 degrees. In this embodiment, the rotary motor 82 can also be replaced by a rotary cylinder.

[0088] Another possible implementation, refer to Figure 8 , Figure 8 This is a schematic diagram showing the structure of a lamp assembly 100 provided in this application, where the shield 60 is driven by another driving module 70. The driving component 80 can be a linear motor 81, and the transmission component 90 can be a connecting rod 91. The body of the linear motor 81 is connected to the housing 10, one end of the connecting rod 91 is connected to the output shaft of the linear motor 81, and the shield 60 is connected to the other end of the connecting rod 91. (See reference...) Figure 8 In (a), when the light source module 20 is in the second mode, the shielding plate 60 is located below the light source module 20, the shielding surface of the shielding plate 60 is away from the light outlet 21, and the shielding surface is perpendicular to the main optical axis L of the light source module 20. (Reference) Figure 8 In section (b), when the light source module 20 switches from the second mode to the first mode, the linear motor 81 drives the baffle plate 60 to move upward via the connecting rod 91, so that the baffle surface of the baffle plate 60 moves to block part of the light outlet 21 of the light source module 20, preventing light from hitting the housing structure 50. At this time, the baffle surface is still perpendicular to the main optical axis L of the light source module 20. In this embodiment, the linear motor 81 can also be replaced by a linear cylinder. The up-down direction here is the first direction mentioned above.

[0089] Alternatively, the shield 60 can also be located above the light source module 20. When the shield 60 needs to block part of the light outlet 21, the linear motor 81 drives the shield 60 to move downward through the connecting rod 91.

[0090] Optionally, refer to Figure 9 , Figure 9 This is a schematic diagram illustrating a different type of shielding plate 60 provided in the lamp assembly 100 of this application embodiment. The shielding plate 60 can also be located on the left side of the light source module 20 (e.g., Figure 9 As shown in (a), when the baffle plate 60 needs to block part of the light outlet 21, the linear motor 81 drives the baffle plate 60 to move to the right via the connecting rod 91 (as shown in (a)). Figure 9 (As shown in (b)). Alternatively, the shield 60 is located on the right side of the light source module 20. When the shield 60 needs to block part of the light outlet 21, the linear motor 81 drives the shield 60 to move to the right via the connecting rod 91. The left-right direction here is the second direction mentioned above.

[0091] Optionally, refer to Figure 10 , Figure 10 This is a schematic diagram showing the structure of the lamp assembly 100 provided in this application, where the shield 60 is driven by another driving module 70. The driving component 80 can be a rotary motor 82, and the transmission component 90 can be a lead screw mechanism 92. The lead screw mechanism 92 includes a lead screw 921 and a nut 922. One end of the lead screw 921 is connected to the output shaft of the rotary motor 82, and the nut 922 is sleeved on the lead screw 921. The nut 922 and the lead screw 921 are threadedly connected, and the shield 60 is connected to the nut 922. When the light source module 20 needs to switch from a second mode to a first mode, the rotary motor 82 drives the lead screw 921 to rotate, causing the nut 922 to move along the axial direction of the lead screw 921. The nut 922 then drives the shield 60 to move along the axial direction of the lead screw 921. The axial direction of the lead screw 921 can be parallel to either the first or second direction.

[0092] Optionally, refer to Figure 11 , Figure 11 This is a schematic diagram showing the structure of the lamp assembly 100 provided in this application, where the shield 60 is driven by another driving module 70. The driving component 80 can be a rotary motor 82, and the transmission component 90 can be a gear mechanism 93. The gear mechanism 93 can include a gear 931 and a rack 932. The gear 931 is connected to the output shaft of the rotary motor 82 and meshes with the rack 932. The shield 60 is connected to the rack 932. When the light source module 20 needs to switch from the second mode to the first mode, the rotary motor 82 drives the gear 931 to rotate, causing the rack 932 to move linearly. The rack 932 then drives the shield 60 to move linearly, and the direction of the linear movement is parallel to the first direction or the second direction.

[0093] Optionally, refer to Figure 12 , Figure 12 This is a schematic diagram of the structure of the lamp assembly 100 provided in this application embodiment, in which the shield 60 is driven by another driving module 70. The driving component 80 can be a rotary motor 82, and the transmission component 90 can be a cam mechanism 94. The cam mechanism 94 includes a cam 941 and a driven wheel 942. The cam 941 is connected to the output shaft of the rotary motor 82 and abuts against the driven wheel 942. The shield 60 is connected to the driven wheel 942. When the light source module 20 needs to switch from the second mode to the first mode, the rotary motor 82 drives the cam 941 to rotate. The driven wheel 942 rolls along the outer periphery of the cam 941. Because the outer periphery of the cam 941 has a protrusion, as the cam 941 rotates, the cam 941 drives the driven wheel 942 to move linearly. The driven wheel 942 will drive the shield 60 to move linearly. The direction of the linear movement is parallel to the first direction or the second direction.

[0094] In other embodiments, reference is made to Figure 13 and Figure 14 , Figure 13 This is a schematic diagram showing a different type of shielding plate 60 provided for the light source module 20 of the lamp assembly 100 in this embodiment of the application. Figure 14 A state transition diagram is provided for the light source module 20 of the lamp assembly 100 provided in this application embodiment, which is equipped with another type of shielding plate 60. The shielding plate 60 includes a first shielding plate 61 and a second shielding plate 62. In the second mode, the first shielding plate 61 and the second shielding plate 62 are located on both sides of the light outlet 21, and the light outlet 21 is not blocked. In the first mode, the first shielding plate 61 and the second shielding plate 62 move synchronously to block a portion of the light outlet 21 respectively. The first shielding plate 61 and the second shielding plate 62 can share a single driving member 80, or a separate driving member 80 can be configured for each of the first shielding plate 61 and the second shielding plate 62. The method by which the driving member 80 drives the first shielding plate 61 and the second shielding plate 62 can be referred to the above embodiment.

[0095] When the light source module 20 is in the first mode, the first shielding plate 61 and the second shielding plate 62 move synchronously to block part of the light outlet 21, which can quickly filter stray light.

[0096] In one possible implementation, refer to Figure 14 In (a), in the second mode, the first shield 61 is located to the left of the light outlet 21, and the second shield 62 is located to the right of the light outlet 21. (See reference) Figure 14 In (b), when switching from the second mode to the first mode, the first shield 61 moves to the right and the second shield 62 moves to the left until the right end of the first shield 61 and the left end of the second shield 62 come into contact, and the first shield 61 and the second shield 62 together block the lower part of the light outlet 21.

[0097] Another possible implementation, refer to Figure 15 , Figure 15 A state transition diagram showing the provision of another type of shielding plate 60 for the light source module 20 of the lighting assembly 100 provided in this embodiment. (See reference...) Figure 15 In (a), in the second mode, the first shield 61 is located to the left of the light outlet 21, and the second shield 62 is located to the right of the light outlet 21. (See reference) Figure 15 In (b), when switching from the second mode to the first mode, the first shield 61 rotates counterclockwise and the second shield 62 rotates clockwise until the right end of the first shield 61 and the left end of the second shield 62 come into contact, and the first shield 61 and the second shield 62 together block the lower part of the light outlet 21.

[0098] In other embodiments, reference is made to Figure 16 , Figure 16This is a schematic diagram of a different type of shielding plate 60 provided for the light source module 20 of the lamp assembly 100 provided in this application embodiment.

[0099] The shielding plate 60 includes a plurality of louvers 63. In the first mode, the angle between the surface of the plurality of louvers 63 and the main optical axis of the light source module is greater than or equal to a first angle, and the distance between any two adjacent louvers 63 is less than or equal to a first distance, thereby blocking a portion of the light outlet 21. In the second mode, the angle between the surface of the plurality of louvers 63 and the main optical axis of the light source module 20 is less than or equal to a second angle, and the distance between any two adjacent louvers 63 is greater than or equal to the second distance, allowing the light beam from the light source module 20 to pass through the gap between any two adjacent louvers 63. The first distance is less than the second distance, and the first angle is greater than the second angle. Both the first distance and the second distance are distances between two adjacent louvers along a direction parallel to the main optical axis of the light source module 20.

[0100] For example, the angle between the surface of the veneer 63 and the main optical axis of the light source module is between 0 degrees and 90 degrees. Optionally, the first angle can be greater than or equal to 0 degrees and less than or equal to 45 degrees, and the second angle can be greater than 45 degrees and less than or equal to 90 degrees. For example, the first angle can be 0 degrees, 10 degrees, 20 degrees, 30 degrees, 40 degrees, or 45 degrees. When the first angle is 0 degrees, the surfaces of the plurality of veneers 6363 are perpendicular to the main optical axis L of the light source module 20. The second angle can be 46 degrees, 50 degrees, 60 degrees, 65 degrees, 75 degrees, 85 degrees, or 90 degrees. When the second angle is 90 degrees, the surfaces of the plurality of veneers 6363 are parallel to the main optical axis of the light source module 20.

[0101] For example, the first distance is less than or equal to 5 millimeters (mm), and the second distance is greater than 5 millimeters. Optionally, the first distance can be 0mm, 1mm, 2mm, 3mm, 4mm, or 5mm. When the first distance is 0mm, two adjacent louvers 63 are in contact with each other. The second distance can be 6mm, 7mm, 8mm, 9mm, or 10mm, etc.

[0102] In one possible implementation, refer to Figure 17 , Figure 17 A state transition diagram for setting another type of shielding plate 60 in the light source module 20 of the lamp assembly 100 provided in this application embodiment. In the second mode, refer to Figure 17 In (a), the surfaces of multiple louvers 63 are parallel to the main optical axis L of the light source module 20. The multiple louvers 63 can be arranged sequentially along a first direction. The second distance between any two adjacent louvers 63 is equal to the width of the louver. The light beam from the light source module 20 can pass through the gap between any two adjacent louvers 63. In this case, the influence of the multiple louvers 63 on the light beam is minimized. (Reference) Figure 17 In (b), in the first mode, the surfaces of the multiple louvers 63 are perpendicular to the main optical axis L of the light source module 20. The first distance between any two adjacent louvers 63 is 0, meaning that any two adjacent louvers 63 are in contact to partially block the light outlet 21. At this time, no light is exposed between two adjacent louvers 63, which can better block the light outlet 21 and avoid glare or stray light. This contact includes errors; if there is a tiny gap between two adjacent louvers 63, it is also considered contact. The multiple louvers 63 can move synchronously to quickly block the light outlet 21, which can improve the efficiency of filtering stray light and make the projected image clear quickly. In addition, the small size of a single louver 63 can increase the flexibility of the layout. The louvers 63 can also flexibly adjust the amount of light transmitted, and the louvers can be adjusted according to the clarity of the projected image, so that the louvers can block stray light without affecting the brightness of the projected image.

[0103] refer to Figure 18 , Figure 18 The state transition diagram of the light source module 20 of the lamp assembly 100 provided in this application embodiment is provided with another type of shield 60. Figure 17 The difference in the implementation method is that the multiple louvers 63 are arranged sequentially along the second direction. The method by which the multiple louvers 63 switch from the first mode to the second mode can be referred to the above embodiment.

[0104] The principle by which multiple louvers 63 block and expose the light-exposing opening 21 is similar to the working principle of venetian blinds, which is briefly described below: (Reference) Figure 19 , Figure 19 This is a schematic diagram of another type of shield 60 in the lighting assembly 100 provided in this application, driven by a drive module 70. Multiple louvers 63 are driven by a single drive module 70, and each louver 63 has a sliding groove 64. The drive module 70 may include a drive component 80 and a transmission component 90. The drive component 80 may be a rotary motor 82, and the transmission component 90 may be a worm gear mechanism 95. The worm gear mechanism 95 includes a rope 951, a turbine 952, a worm 953, and a mounting rod 954. The rope 951 passes through the sliding grooves 64 of the multiple louvers 63, connecting them in series. The turbine 952 is fixed to the mounting rod 954, the worm 953 meshes with the turbine 952, and the rope 951 is wound around the protrusion 955 of the mounting rod 954. When the worm gear 953 is rotated, the worm gear 953 drives the turbine 952 to rotate, the turbine 952 drives the mounting rod 954 to rotate, the mounting rod 954 drives the rope 951 to move, so that the rope 951 slides in the sliding groove 64, and the rope 951 can drive the louvers 63 to rotate, so that multiple louvers 63 can block the light outlet 21.

[0105] Optionally, multiple louvers 63 can also be driven by multiple drive modules 70, and this application does not impose any restrictions.

[0106] refer to Figure 20 , Figure 20 This is a schematic diagram of the structure of the terminal 1000 provided in an embodiment of this application.
