Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

The specific meaning of the above terms in this application will be understood by a person skilled in the art based on the specific circumstances.

[0020] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a cabinet door, which includes a door panel 102 and a mirror 101 disposed on the door panel 102. The mirror 101 is provided with a first light-emitting hole 103 and a second light-emitting hole 104 that penetrates along the thickness direction of the cabinet door. The door panel 102 is provided with a first light-emitting system and a second light-emitting system inside.

[0022] The beam output end of the first projection system is set relative to the first light outlet 103, and the beam output end of the second projection system is set relative to the second light outlet 104. The illumination beams formed by the first projection system and the second projection system have different tilt angles relative to the mirror 101.

[0023] Specifically, the cabinet door of this utility model embodiment can be installed on a mirror cabinet in places such as bathrooms and public toilets.

[0024] Mirror 101 is made of glass with a reflective coating. Mirror 101 is adhered to and covers door panel 102. The first light-emitting hole 103 and the second light-emitting hole 104 are located at the same height, in the middle area of ​​the upper part of mirror 101, and are of the same size. The initial propagation direction of the first illumination beam is opposite to that of the second illumination beam. After the two illumination beams propagate to the middle area of ​​door panel 102, they are emitted through the corresponding light-emitting holes.

[0025] Since the initial propagation direction of the first illumination beam is along the optical axis, the components in the first projection system can be arranged along the optical axis, i.e., the width direction of the cabinet door. Similarly, the components in the second projection system can also be arranged along the width direction of the cabinet door.

[0026] The optical axes of the first and second projection systems are parallel to the width direction of the cabinet door. The first and second projection systems can be positioned at the same height within the door panel 102 and parallel to the horizontal direction, or they can be positioned at different heights within the door panel 102. In a preferred embodiment, the first and second projection systems are symmetrically arranged with respect to the vertical central axis of the door panel 102 and are both parallel to the horizontal direction. The first light-emitting hole 103 and the second light-emitting hole 104 are located in the middle of the mirror 101 and are at the same height as either the first or second projection system. A beam deflector is provided at the end of the first and second projection systems, i.e., the beam output end, so that the illumination beam is emitted through the corresponding light-emitting hole. It should be understood that the direction of the beam emitted from both light-emitting holes faces the usage direction of the mirror 101 on the door panel 102.

[0027] Since the door panel 102 is relatively thin, generally with a thickness of ≤16mm, that is, the thickness in the Z-axis direction is limited. The total length of the first and second light-projection systems is relatively long, much greater than 12mm. In order to place the first and second light-projection systems in the cabinet door, the light needs to be redirected. In this way, the first and second light-projection systems can be placed in the limited cabinet door space. The optical components can be arranged sequentially along the width direction of the cabinet door, that is, the X-axis direction, and embedded in the door panel 102.

[0028] This utility model discloses a cabinet door and mirror cabinet with a dual-projection system. The mirror 101 has a first light-emitting hole 103 and a second light-emitting hole 104 extending along the thickness of the cabinet door. The door panel 102 contains a first projection system and a second projection system. The first and second projection systems adjust the propagation angle of the illumination beam to different degrees, generating two light spots with different reflection angles that exit through corresponding light-emitting holes. This allows optical components to be arranged along the width of the cabinet door, solving the problem of difficulty in assembling optical components inside the thin cabinet door. Furthermore, by assembling the optical components inside the cabinet door, the integrity of the mirror 101 is ensured, and two light spots with different tilt angles can be output separately, adapting to lighting needs at different distances.

[0029] In some embodiments, the first projection system includes a first light source 201, a first beam shaping module, and a first reflector 208 disposed inside the door panel 102 and arranged sequentially along the positive direction of the optical axis; the second projection system includes a second light source 301, a second beam shaping module, and a second reflector 308 disposed inside the door panel 102 and arranged sequentially along the negative direction of the optical axis, wherein the positive direction of the optical axis and the negative direction of the optical axis are opposite.

[0030] Specifically, the first light source 201 and the second light source 301 are used to generate a first illumination beam and a second illumination beam, respectively; the first beam shaping module is used to shape the first illumination beam and output it to the first reflector 208, and the second beam shaping module is used to shape the second illumination beam and output it to the second reflector 308; the first reflector 208 is tilted to the optical axis and is positioned relative to the first light-emitting hole 103 along the thickness direction of the cabinet door, and is used to reflect the received first illumination beam to the first light-emitting hole 103 and emit it through the first light-emitting hole 103; the second reflector 308 is tilted to the optical axis and is positioned relative to the second light-emitting hole 104 along the thickness direction of the cabinet door, and is used to reflect the received beam to the second light-emitting hole 104 and emit it through the second light-emitting hole 104, wherein the tilt angle of the first reflector 208 is different from the tilt angle of the second reflector 308.

[0031] The first illumination beam emitted by the first light source 201 is emitted through the first light-emitting hole 103 on the mirror 101, and the second illumination beam emitted by the second light source 301 is emitted through the second light-emitting hole 104 on the mirror 101. Furthermore, in order to install a detector, such as a human infrared detector, a detection hole adapted to the detector's signal transmission and reception is provided between the first light-emitting hole 103 and the second light-emitting hole 104.

[0032] The first light source 201 uses LED light beads, which can be a single light bead or a multi-light bead light source, and its light emission direction is towards the first beam shaping module. The first light source 201 and the second light source 301 have the same structure and light emission parameters.

[0033] The first and second beam shaping modules can employ optical devices such as apertures, convex lenses, or concave lenses to shape and converge the input beam to the corresponding reflector.

[0034] Both the first reflector 208 and the second reflector 308 are tilted relative to the optical axis, which is parallel to the width direction of the cabinet door, i.e., the X-axis direction. For example... Figure 3As shown, the height direction of the cabinet door is parallel to the Y-axis, and the thickness direction is parallel to the Z-axis. Specifically, the projection of the first reflector 208 along the thickness direction of the cabinet door falls at least partially within the first light-emitting aperture 103, and the projection of the second reflector 308 along the thickness direction of the cabinet door falls at least partially within the second light-emitting aperture 104. The first reflector 208 is at a certain angle to the X-axis to reflect the light beam propagating along the X-axis to be emitted along the Z-axis through the first light-emitting aperture 103, and the first reflector 208 is at a certain angle to the Y-axis to tilt the light beam downwards at a certain angle. The downward tilt angle of the light beam reflected by the second reflector 308 after exiting through the second light-emitting aperture 104 is different from the downward tilt angle of the first reflector 208, thus obtaining two light spots with different emission angles.

[0035] To accommodate both the first and second light-projection systems within the cabinet door, this embodiment of the invention includes a first reflector 208 and a second reflector 308 to redirect the light beam. This allows for placement of both systems within the limited space of the cabinet door. Optical components can be arranged sequentially along the width of the cabinet door (X-axis) and embedded within the door panel 102, providing sufficient space for a beam-shaping module to adjust the beam. By setting different tilt angles for the first reflector 208 and the second reflector 308, the first light-emitting aperture 103 and the second light-emitting aperture 104 each output light spots with two emission angles, adapting to lighting needs at different distances.

[0036] In some embodiments, the first beam shaping module includes a first lens group, a first light-transmitting plate 204, and a second lens group arranged sequentially along the positive direction of the optical axis; the first lens group is used to collimate the illumination beam generated by the first light source 201; the first light-transmitting plate 204 is provided with a light-transmitting hole 2041, which is used to constrain the shape of the illumination beam through the light-transmitting hole 2041; the second lens group is used to converge the illumination beam and emit it to the first reflector 208.

[0037] The second beam shaping module includes a third lens group, a second light-transmitting plate 304, and a fourth lens group arranged sequentially along the negative direction of the optical axis; the third lens group is used to collimate the illumination beam generated by the second light source 301; the second light-transmitting plate 304 is provided with a light-transmitting hole 2041, which is used to constrain the shape of the illumination beam through the light-transmitting hole 2041; the fourth lens group is used to converge the illumination beam and emit it to the second reflector 308.

[0038] The first lens group and the third lens group have the same structure, the first light-transmitting plate 204 and the second light-transmitting plate 304 have the same structure, and the focal length of the second lens group is greater than that of the fourth lens group.

[0039] Among them, the focal length of the second lens group Taking the calculation formula as an example, it satisfies:

[0040] In the formula, The distance between the illuminated area and the mirror surface. The height difference between the center point of the lighting area and the light-emitting aperture. The entrance pupil diameter of the second lens group is... This represents the diameter of the light spot in the illuminated area. Generally, The range is between 300mm and 500mm. The range is between 300mm and 500mm. The range is between 340mm and 400mm.

[0041] Because the cabinet door is relatively thin, the diameter of all the lenses is limited, thus... Limited. If If the light spot is too small, the diameter of the light spot will be very large, and the brightness will be reduced. If the light spot is too large, the diameter of the light spot will be very small, and the brightness will be increased, but the diameter of the light spot in the illuminated area will be smaller, and the irradiated area will be smaller.

[0042] when Only when the above formula is satisfied can a reasonable effective focal length be designed within a limited thickness. The above formula must also be satisfied.

[0043] Furthermore, the focal length of the second lens group The focal length of the fourth lens group satisfy:

[0044] Within this range, the focal length can meet the requirements of small thickness while taking into account the size of the light spot and the brightness of the illumination.

[0045] Since the focal length of the second lens group is greater than that of the fourth lens group, the second lens group has a weaker ability to converge the light beam than the fourth lens group. This allows the light emission angle of the first projection system to be smaller than that of the second projection system, thereby obtaining two light spots of different sizes to meet different lighting needs.

[0046] Furthermore, in the first beam shaping module, the first lens group includes a first lens 202 and a second lens 203 arranged sequentially along the positive direction of the optical axis, and both the first lens 202 and the second lens 203 are plano-convex lenses.

[0047] The primary function of the first lens group is to shape the first illumination beam output from the first light source 201 into parallel or nearly parallel light, facilitating subsequent adjustment of the beam's exit angle via the second lens group. In the second beam shaping module, the third lens group includes a sixth lens 302 and a seventh lens 303 arranged sequentially along the negative direction of the optical axis. The first lens 202 and the sixth lens 302 have identical structures, as do the second lens 203 and the seventh lens 303. The third lens group shapes the second illumination beam output from the second light source 301 into parallel or nearly parallel light. Depending on actual needs, the parameters of each lens in the first and second lens groups can be adjusted to collimate the illumination beam.

[0048] In some embodiments, the second lens group includes a third lens 205, a fourth lens 206, and a fifth lens 207 arranged sequentially along the positive direction of the optical axis. The third lens 205, the fourth lens 206, and the fifth lens 207 are all meniscus lenses and are all positive lenses.

[0049] Specifically, the focal length of the second lens group is 14.6mm. The specific parameters of the third lens 205, the fourth lens 206, and the fifth lens 207 can be determined through optical simulation. Further, the fourth lens group includes an eighth lens 305, a ninth lens 306, and a tenth lens 307 arranged sequentially along the negative direction of the optical axis. The eighth lens 305 and the tenth lens 307 are both meniscus lenses and both are positive lenses, while the ninth lens 306 is a biconvex lens.

[0050] Specifically, the focal length of the fourth lens group is 11.6 mm. The specific parameters of the eighth lens 305, the ninth lens 306, and the tenth lens 307 can be determined through optical simulation. In some embodiments, the light emission angle of the first projection system... The light output angle is smaller than that of the second projection system. . Specifically, the light angle and light angle All of the following must be met:

[0051] In the formula, The light output angle of the first projection system or the light output angle of the second projection system.

[0052] Specifically, since the thickness of the mirror cabinet door panel 102 is ≤16mm, and considering the thickness of the outer shell (2mm) and the reserved thickness of the door panel 102 (2mm), the maximum effective size of the lens in the second lens group should be ≤12mm, and the entrance pupil diameter of the second lens group should be... ,but ≤12mm. The range is between 300mm and 500mm. Therefore, we can obtain: 32° < < <53°.

[0053] In some embodiments, the light-transmitting aperture 2041 is elliptical in shape.

[0054] Specifically, such as Figure 4 As shown, the normal of the first light-transmitting plate 204 is parallel to the optical axis. In the first light-transmitting plate 204, the light-transmitting aperture 2041 is located at the center of the first light-transmitting plate 204, and the center of the light-transmitting aperture 2041 is located on the optical axis. Most of the parallel light emitted from the first lens group is emitted through the light-transmitting aperture 2041, and a small portion is absorbed by the first light-transmitting plate 204. The major axis of the ellipse of the light-transmitting aperture 2041 makes an angle of 45° with the Z-axis. The second light-transmitting plate 304 is installed in the same way as the first light-transmitting plate 204.

[0055] In order to ensure that the light spot in the XY coordinate plane of the illumination area is circular, the light spot before passing through the first reflector 208 or the second reflector 308 must be elliptical; otherwise, it cannot become circular after reflection. Therefore, by setting elliptical light-transmitting holes 2041 in the first light-transmitting plate 204 and the second light-transmitting plate 304, the final emitted light spot can be circular, thus matching the illumination requirements.

[0056] In some embodiments, such as Figure 5 As shown, the angle between the normal of the first reflector 208 and the width direction of the cabinet door is 45°, the angle between the normal of the second reflector 308 and the width of the cabinet door is 45°, and the angle between the normal of the first reflector 208 and the height direction of the cabinet door is... The angle between the normal of the second reflecting mirror 308 and the height direction of the cabinet door is greater than the angle between the normal of the second reflecting mirror 308 and the height direction of the cabinet door. .

[0057] Specifically, in combination Figure 5 , Figure 6 and Figure 7 As shown, the optical axis after reflection by the first reflector 208 forms a 90° angle with the optical axis before reflection. Therefore, the normal of the first reflector 208 is located at the exact midpoint between the light rays before and after reflection, meaning the first reflector 208 forms a 45° angle with the width direction of the cabinet door. Similarly, the second reflector 308 forms a 45° angle with the width direction of the cabinet door.

[0058] Regarding the height direction of the cabinet door, the following relationship exists:

[0059] in, This represents the angle between the normal of the first reflecting mirror 208 and the height direction of the cabinet door. Or the angle between the normal of the second reflector 308 and the height direction of the cabinet door. Generally speaking, for the general... and The value of , the included angle The value ranges from 65.3° to 72.5°, which is the angle between the normal of the first reflecting mirror 208 and the height direction of the cabinet door. The angle between the normal of the second reflecting mirror 308 and the height direction of the cabinet door satisfy: The angle setting, combined with the aforementioned elliptical light-transmitting aperture 2041, allows the light spot in the illumination area after passing through the reflector to be nearly circular, thus meeting the needs of facial illumination.

[0060] This utility model embodiment also provides a mirror cabinet, including a cabinet door with a dual-projection system as described in any of the above embodiments of this utility model.

[0061] Mirrored cabinets are typically used in bathrooms, toilets, and similar locations. Figure 8 As shown, the mirror cabinet also includes a cabinet body 105, and the cabinet door is connected to the cabinet body 105 by hinges.

[0062] Although the exemplary embodiments and their advantages have been described in detail, those skilled in the art can make various changes, substitutions and modifications to these embodiments without departing from the spirit and scope of protection of this utility model, and such modifications and variations all fall within the scope defined by the present invention.
