[0021] 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.

[0022] 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 light-emitting hole 103 that extends through the thickness direction of the cabinet door. Inside the door panel 102, a first light source 201, a beam shaping module and a reflector 208 are arranged sequentially along the optical axis direction. The optical axis direction is parallel to the width direction of the cabinet door. The reflector 208 is inclined to the optical axis and is disposed relative to the light-emitting hole 103.

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

[0024] The mirror 101 is made of glass and has a reflective layer on its surface. The mirror 101 is pasted and covered on the door panel 102. The light emitted by the first light source 201 is reflected by the beam shaping module and the reflector 208 and then emitted from the light outlet 103 on the mirror 101.

[0025] The first light source 201 uses LED lamp beads as its light source, and its light emission direction is towards the beam shaping module. The first light source 201 includes LED lamp beads with at least two color temperatures, where the lower color temperature is 2700K and the higher color temperature is 6500K. They can be driven to emit light in single color temperature and emit light in mixed color temperature, thereby realizing the change of light color temperature, which varies between 2700K and 6500K.

[0026] The beam shaping module can use optical devices such as apertures, convex lenses or concave lenses to shape and converge the input beam to the reflector 208.

[0027] The reflector 208 is 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 3 As 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 light-emitting aperture 103 is located above the mirror 101. The reflector 208 is at a certain angle to the X-axis to reflect the light beam propagating along the X-axis to the Z-axis, and the reflector 208 is at a certain angle to the Y-axis to tilt the light beam downwards at a certain angle. The projection of the reflector 208 along the thickness direction of the cabinet door is at least partially located within the light-emitting aperture 103 to reflect the light beam through the light-emitting aperture 103.

[0028] 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, and the total length of the beam shaping module is relatively long, much greater than 12mm, in order to place the first light source 201 and the beam shaping module in the cabinet door, a reflector 208 needs to be set to redirect the light. In this way, the first light source 201 and the beam shaping module can be placed in the limited cabinet door space. The optical devices 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.

[0029] In this embodiment of the invention, the cabinet door has a first light source 201, a beam shaping module, and a reflector 208 arranged sequentially along the optical axis inside the door panel 102. The beam shaping module shapes the illumination beam generated by the first light source 201 along the width direction of the cabinet door and then reflects it out through the reflector 208, so that the optical devices can be arranged along the width direction of the cabinet door. This solves the problem that it is difficult to assemble optical devices inside the cabinet door because the cabinet door is thin, and thus the optical devices can be assembled inside the cabinet door, ensuring the integrity of the mirror 101.

[0030] In some embodiments, the beam shaping module includes a first lens group, a first light-transmitting plate 204, and a second lens group arranged sequentially along the optical axis; the first lens group is used to collimate the illumination beam; 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 reflector 208.

[0031] Specifically, the first lens group includes a first lens 202 and a second lens 203 arranged sequentially along the optical axis, both of which are plano-convex lenses.

[0032] The main function of the first lens group is to shape the beam output from the first light source 201 into parallel or nearly parallel light, facilitating subsequent adjustment of the beam's exit angle by the second lens group. Those skilled in the art can use optical design software to set the parameters and positional relationship between the first lens 202 and the second lens 203 in the first lens group, thereby shaping the beam output from the first light source 201 into parallel or nearly parallel light.

[0033] Furthermore, the second lens group includes at least two positive lenses, and the effective focal length of the second lens group is... satisfy:

[0034] 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 103. The entrance pupil diameter of the second lens group is... The diameter of the light spot in the illuminated area.

[0035] 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.

[0036] when Only when the above formula is satisfied can a reasonable effective focal length be designed within a limited thickness. The value range is 10mm-15mm. This focal length can meet the requirements of small thickness while taking into account the size of the light spot. It is related to the light cone angle.

[0037] By comprehensively considering factors such as the entrance pupil diameter of the second lens group, the distance between the illumination area and the mirror, the height difference between the center point of the illumination area and the light exit aperture 103, and the light spot diameter of the illumination area, the effective focal length of the second lens group can be accurately calculated according to the actual lighting requirements, thereby optimizing the design of the second lens group, enabling the light beam to form a suitable light spot in the illumination area, and improving the uniformity and accuracy of the illumination.

[0038] 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 optical axis. The third lens 205 and the fifth lens 207 are both meniscus lenses and both are positive lenses, while the fourth lens 206 is a biconvex lens. By employing the combination of two meniscus lenses and a biconvex lens, the emitted light beam can be converged on the reflector to form a suitable illumination spot.

[0039] Furthermore, the maximum light output angle is achieved primarily through the optical system composed of the first and second lens groups described above. (Maximum in the X direction) is:

[0040] 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.

[0041] The arrangement of the aforementioned optical components allows for a more compact structure of the beam shaping module, reducing its space requirements and facilitating installation.

[0042] In some embodiments, such as Figure 4 As shown, the light-transmitting hole 2041 is elliptical in shape, and the angle between the major axis of the ellipse of the light-transmitting hole 2041 and the thickness direction of the cabinet door is... satisfy:

[0043] In the formula, The distance between the illuminated area and the mirror surface. This is the height difference between the center point of the illuminated area and the light-emitting aperture 103. Generally, The range is between 300mm and 500mm. The range is between 300mm and 500mm. The range is between 340mm and 400mm.

[0044] To ensure that the light spot in the XY coordinate plane of the illuminated area is circular, the light spot before reflecting mirror 208 must be elliptical; otherwise, it cannot become circular after reflection. Generally, for ordinary... and The value of , the included angle The value range is from 34° to 53°, and preferably, the included angle is... The value is 45°.

[0045] Specifically, because the light rays after passing through mirror 208 exit at a certain angle to the Z-axis, and the Z-axis forms a 90° angle with the X-axis, the major axis of the ellipse of the light aperture 2041 is twice the minor axis; and because the optical axis after passing through mirror 208 has a certain angle with the Z-axis, when and When they are equal, for example, both are 350mm, the included angle is... The angle is 45°, when they are not equal, such as when When, the included angle With an angle of 38.6°, the light spot in the illumination area after passing through the reflector 208 is nearly circular, which meets the needs of facial lighting.

[0046] In some embodiments, combined with Figure 5 , Figure 6 and Figure 7 As shown, the angle between the normal of reflector 208 and the width direction of the cabinet door is 45°, and the angle between the normal of reflector 208 and the height direction of the cabinet door is... satisfy:

[0047] Specifically, the optical axis after reflection by mirror 208 is at 90° to the optical axis before reflection. Therefore, the normal of mirror 208 is located at the exact midpoint between the light rays before and after reflection, that is, at 45° to the width direction of the cabinet door.

[0048] Generally speaking, for the general and The value of , the included angle The value range is from 65.3° to 72.5°. Combined with the aforementioned elliptical light-transmitting aperture 2041, the light spot in the illumination area after passing through the reflector 208 is close to a circle, which meets the needs of face illumination.

[0049] This utility model also provides a mirror cabinet, including cabinet doors as described in any of the above embodiments of this utility model.

[0050] Mirrored cabinets are typically used in bathrooms, toilets, and similar locations. Figure 8 As shown, the mirror cabinet also includes a cabinet body 104, and the cabinet door is connected to the cabinet body 104 by hinges.

[0051] 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.
