[0031] An illuminating device for a mirror cabinet provided by an embodiment of the present utility model can be applied to mirror cabinets in various scenarios such as bathrooms, toilets, bedrooms, etc. The illuminating device for the mirror cabinet can make the emitted light deflect towards the front of the mirror, thereby meeting the lighting requirements of users when using the mirror cabinet for makeup, grooming, and other behaviors.

[0032] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, an embodiment of the present utility model provides an illuminating device for a mirror cabinet, including: a diffusion plate 1, including an optical main body 11, a left side wall 12 and a right side wall 13 respectively connected to the left and right ends of the optical main body 11. A first inner bending protrusion 121 is provided at the lower end of the left side wall 12, and a second inner bending protrusion 131 is provided at the lower end of the right side wall 13; a housing 2, including a bottom plate 22, a left side plate 21 and a right side plate 23 respectively provided at the left and right ends of the bottom plate 22. The left side plate 21 and the right side plate 23 are located on the same side of the bottom plate 22. A first groove 211 for mating and clamping with the first inner bending protrusion 121 is provided on the outer side of the left side plate 21, and a second groove 231 for mating and clamping with the second inner bending protrusion 131 is provided on the outer side of the right side plate 23.

[0033] Specifically, the diffusion plate 1 is formed by an extrusion process, and its material is an optical plastic, including but not limited to polymethyl methacrylate (PMMA), polycarbonate (PC), polyvinyl chloride (PVC), etc. A little diffusion powder is added to the optical plastic, and the diffusion plate 1 is uniformly arranged in the optical plastic, so that the emitted light undergoes diffuse scattering, achieving the effect of soft and non-glare light.

[0034] The optical main body 11, the left side wall 12 and the right side wall 13 in the diffusion plate 1 are of an integral structure. The left side of the optical main body 11 extends downward to form the left side wall 12, and the lower end of the left side wall 12 bends upward towards the inside to form the first inner bending protrusion 121. The right side of the optical main body 11 extends downward to form the left side wall 12, and the lower end of the left side wall 12 bends upward towards the inside to form the second inner bending protrusion 131.

[0035] The bottom plate 22, the left side plate 21 and the right side plate 23 in the housing 2 are of an integral structure, and its material can be plastic, metal, etc.

[0036] The first groove 211 is provided on the outer side of the left side plate 21 and can be formed by bending the left side plate 21 or by providing a groove on the left side plate 21.

[0037] The second groove 231 is provided on the right side of the right side plate 23 and can be formed by bending the right side plate 23 or by providing a groove on the right side plate 23.

[0038] A mirror cabinet lighting device according to an embodiment of the present utility model is provided with a first inner bending protrusion 121 at the lower end of the left side wall 12 of the diffusion plate 1, and a second inner bending protrusion 131 at the lower end of the right side wall 13. A first groove 211 that cooperates and engages with the first inner bending protrusion 121 is provided on the outer side of the left side plate 21 of the housing 2, and a second groove 231 that cooperates and engages with the second inner bending protrusion 131 is provided on the outer side of the right side plate 23. During assembly, after installing the internal components in the housing 2, it is only necessary to align the first inner bending protrusion 121 and the second inner bending protrusion 131 of the diffusion plate 1 with the first groove 211 and the second groove 231, and then push them in to complete the assembly. The assembly process is simple and convenient, which is conducive to improving the assembly efficiency.

[0039] In some embodiments, the mirror cabinet lighting device further includes a light source plate 5, on which a light source 6 is provided. A first mounting portion is provided on the inner side of the left side plate 21, and a second mounting portion opposite to the first mounting portion is provided on the bottom plate 22. The light source plate 5 is mounted in the housing 2 through the first mounting portion and the second mounting portion.

[0040] Specifically, since the first mounting portion is provided on the left side plate 21 and its height is greater than that of the second mounting plate, the installed light source plate 5 is inclined upward to the right, so that the light emitted by the light source 6 is deflected to the right.

[0041] In an example, by reasonably setting the positions of the first mounting groove 214 and the second mounting groove 223, the main optical axis of the light source plate 5 is set to deviate in the first direction, and the angle between the main optical axis and the vertical direction is:

[0042]

[0043] In the formula, θ 光轴 is the angle between the main optical axis and the vertical direction, w is the width of the diffusion plate 1, w1 is the horizontal distance between the light source 6 and one end of the diffusion plate 1, and h is the vertical distance between the light source 6 and the diffusion plate 1.

[0044] By setting the main optical axis to be inclined according to the above formula, the main optical axis of the light source plate 5 can irradiate the central position of the diffusion plate 1, mainly reducing the light that cannot directly irradiate the diffusion plate 1, so that as much light as possible irradiates the diffusion plate 1, and avoiding excessive energy loss.

[0045] Further, the first mounting portion includes a first mounting protrusion 212 and a second mounting protrusion 213 extending into the interior of the housing 2. A first mounting groove 214 is formed by the first mounting protrusion 212 and the second mounting protrusion 213. The second mounting portion includes a third mounting protrusion 221 and a fourth mounting protrusion 222 extending respectively towards the first mounting protrusion 212 and the second mounting protrusion 213. A second mounting groove 223 is formed by the third mounting protrusion 221 and the fourth mounting protrusion 222. Both ends of the light source board 5 are respectively mounted in the first mounting groove 214 and the second mounting groove 223.

[0046] The light source board 5 can be fixed through the first mounting groove 214 and the second mounting groove 223, preventing the light source board 5 from shaking and improving the lighting stability.

[0047] Further, a polarizing lens 7 is provided on the light source board 5. The polarizing lens 7 includes a second incident surface 71 and a second exit surface 72. The curvature of the second incident surface 71 gradually decreases from the left end to the right end of the polarizing lens 7, and the curvature of the second exit surface 72 gradually increases from the left end to the right end of the polarizing lens 7.

[0048] The bottom of the polarizing lens 7 is parallel to the light source board 5, and it can be mounted through the first mounting groove and the second mounting groove simultaneously.

[0049] The polarizing lens 7 is formed by an extrusion process and is made of optical plastic, including but not limited to polymethyl methacrylate (PMMA), polycarbonate (PC), polyvinyl chloride (PVC), etc.

[0050] The polarizing lens 7 is disposed on the light source board 5. The bottom surface of the lens is parallel to the light source board 5, and the polarizing lens 7 and the light source board 5 jointly enclose the light source 6. The light source board 5 can be inclined, and the light source 6 and the polarizing lens 7 are correspondingly inclined so that the emitted light thereof is biased towards the first direction.

[0051] Assuming that the light-emitting surface faces upward, the light source board 5, the polarizing lens 7, and the diffuser plate 1 are arranged from bottom to top in sequence. The polarizing lens 7 and the light source board 5 are inclined and tilted towards the upper right. At this time, the first direction is the direction from left to right. Since the curvature of the second incident surface 71 of the polarizing lens 7 gradually decreases from the left end to the right end of the polarizing lens 7, and the curvature of the second exit surface 72 of the polarizing lens 7 gradually increases from the left end to the right end of the polarizing lens 7, according to the principle of light refraction, the light emitted by the light source 6 can be deflected to the right after passing through the polarizing lens 7, and is generally deflected to the right. In addition, the polarizing lens 7 can also make the light distribution angle of the light source 6 smaller, having the effect of light collection, enabling more light to directly act on the diffuser plate 1, which can improve the light output efficiency and the overall lighting effect is brighter.

[0052] In some embodiments, the mirror cabinet lighting device further includes a first reflector 3 and a second reflector 4. The lower end of the first reflector 3 is connected to the left side plate 21, and the upper end of the first reflector 3 abuts against the inner side of the left side wall 12. The upper end of the second reflector 4 is connected to the right side plate 23, and the lower end of the second reflector 4 is connected to the second mounting portion.

[0053] To increase the reflection efficiency, the surfaces of the first reflector 3 and the second reflector 4 are polished, an electroplated reflective coating is added, or matte treatment is performed. Additionally, a reflective film can be pasted.

[0054] The light emitted by the light source 6 is divided into three parts: left-side light, middle light, and right-side light. Among them, the middle light directly irradiates the diffusion plate 1, the left-side light irradiates the first reflector 3, and the light is reflected to the diffusion plate 1 through the first reflector 3. The right-side light irradiates the second reflector 4, and the light is reflected to the diffusion plate 1 through the second reflector 4.

[0055] By providing the first reflector 3 and the second reflector 4, the left-side light and the right-side light that cannot directly irradiate the diffusion plate 1 can be effectively utilized, improving the energy utilization efficiency and enhancing the lighting effect.

[0056] Furthermore, the bottom plate 22, the left side plate 21, the right side plate 23, the first reflector 3, the second reflector 4, the first mounting portion, and the second mounting portion are of an integrally formed structure.

[0057] By setting the bottom plate 22, the left side plate 21, the right side plate 23, the first reflector 3, the second reflector 4, the first mounting portion, and the second mounting portion as an integrally formed structure, the number of parts is reduced, facilitating assembly.

[0058] In some embodiments, the mirror cabinet lighting device further includes a controller 8 and a power driver 9. The controller 8 is disposed in the cavity formed by the first reflector 3 and the housing 2, and the power driver 9 is disposed in the cavity formed by the second reflector 4 and the housing 2. Alternatively, the controller 8 is disposed in the cavity formed by the second reflector 4 and the housing 2, and the power driver 9 is disposed in the cavity formed by the first reflector 3 and the housing 2.

[0059] The power driver 9 and the controller 8 are mainly for driving and controlling the light source board 5 to enable adjustable color temperature and adjustable brightness.

[0060] In the prior art, the power driver 9 and the controller 8 are placed externally, that is, the power external scheme. In the embodiments of the present invention, the controller 8 and the power driver 9 are placed between the first reflector 3 and the housing 2 and between the second reflector 4 and the housing 2. This can make full use of the space, make the whole compact, and reduce the volume of the mirror cabinet lighting device.

[0061] Furthermore, the left side plate 21 and / or the right side plate 23 is of a "bow" - shaped structure.

[0062] By setting either or both of the left plate 21 and the right plate 23 to a "bow" - shaped structure, the strength of the housing can be improved.

[0063] In some embodiments, the optical body 11 includes a first incident surface 112 and a first exit surface 111. The first exit surface 111 is a plane, and the first incident surface 112 is provided with a plurality of micro - prisms 1121 arranged along a first direction. The micro - prism 1121 includes a first plane 11211 and a second plane 11212. The first plane 11211 and the second plane 11212 of the same micro - prism 1121 are connected to form a wedge - shaped structure, and the tip of the wedge - shaped structure is inclined in the first direction, where the first direction is parallel to the first exit surface 111.

[0064] The first plane 11211 is an optical surface, mainly for refracting the light emitted by the light source 6 and deflecting it in the first direction. The second plane 11212 is a non - optical surface, mainly for connecting the first plane 11211 of the next micro - prism 1121 along the first direction. By distinguishing the functions of the first plane 11211 and the second plane 11212 in this way, it can be ensured that the incident light of the light source 6 can hardly irradiate the second plane 11212, and the light is effectively deflected. At the same time, when the light irradiates the second plane 11212, the light is prevented from deflecting in the opposite direction of the first direction and generating ineffective light.

[0065] Furthermore, the angle between the first plane 11211 and the light - emitting surface and the angle between the second plane 11212 and the light - emitting surface both decrease successively along the first direction. That is, for each micro - prism 1121, the angle between the first plane 11211 of the next micro - prism 1121 along the first direction and the light - emitting surface and the angle between the second plane 11212 and the light - emitting surface are both smaller than those of the previous micro - prism 1121, and decrease successively.

[0066] It should be understood that the angle between the first plane 11211 and the light - emitting surface and the angle between the second plane 11212 and the light - emitting surface are both interior angles of the triangle formed by the first plane 11211, the second plane 11212, and the light - emitting surface.

[0067] By the way that the angle between the first plane 11211 and the light - emitting surface and the angle between the second plane 11212 and the light - emitting surface both decrease successively along the first direction, the purpose of using the first plane 11211 as the optical surface and the second plane 11212 as the non - optical surface is achieved, that is, the light can be refracted out through the first plane 11211 and hardly irradiate the second plane 11212.

[0068] In one example, the angle between the first first plane 11211 arranged in the first direction and the light-emitting surface, that is, the angle between the first plane 11211 of the first micro prism 1121 and the light-emitting surface is:

[0069]

[0070] In the formula, θ1 is the angle between the first first plane 11211 and the light-emitting surface, w1 is the horizontal distance between the light source 6 and the left end of the diffusion plate 1, n0 is the refractive index of the diffusion plate 1, and h is the vertical distance between the light source 6 and the diffusion plate 1.

[0071] The angle between the last first plane 11211 arranged in the first direction and the light-emitting surface, that is, the angle between the first plane 11211 of the last micro prism 1121 and the light-emitting surface is:

[0072]

[0073] In the formula, θ n is the angle between the last first plane 11211 and the light-emitting surface, and w2 is the horizontal distance between the light source 6 and the right end of the diffusion plate 1.

[0074] The decreasing angle of adjacent first planes 11211 is:

[0075]

[0076] In the formula, is the decreasing angle of the first plane 11211, and n is the number of micro prisms 1121.

[0077] Then the angle θ2 between the first plane 11211 of the second micro prism 1121 and the light-emitting surface is:

[0078]

[0079] The angle θ3 between the first plane 11211 of the third micro prism 1121 and the light-emitting surface is:

[0080]

[0081] And so on.

[0082] The angle between the first second plane 11212 arranged in the first direction and the light-emitting surface, that is, the angle between the first micro prism 1121 and the light-emitting surface is:

[0083]

[0084] In the formula, β1 is the angle between the first second plane 11212 and the light-emitting surface;

[0085] The angle between the last second plane 11212 arranged in the first direction and the light-emitting surface, that is, the angle between the last micro prism 1121 and the light-emitting surface is:

[0086]

[0087] In the formula, β n is the angle between the last second plane 11212 and the light-emitting surface;

[0088] The decreasing angle of adjacent second planes 11212 is:

[0089]

[0090] In the formula, is the decreasing angle of the second plane 11212.

[0091] Then the angle β2 between the second plane 11212 of the second micro prism 1121 and the light-emitting surface is:

[0092]

[0093] The angle β3 between the second plane 11212 of the third micro prism 1121 and the light-emitting surface is:

[0094]

[0095] And so on.

[0096] When light is incident obliquely, refraction occurs at the junction of the two media, and the propagation direction changes. Therefore, the light emitted by the light source 6 undergoes refraction and deflection at both the first incident surface 112 and the first exit surface 111 of the diffusion plate 1. By reasonably designing the angles of the first plane 11211 and the second plane 11212 of the micro prism 1121, the deflected light can achieve the purpose of deflection.

[0097] By setting the angles of the first plane 11211 and the second plane 11212 of each micro prism 1121 according to the above conditions, the generation of ineffective polarized light can be minimized as much as possible, and the polarized light effect of the diffusion plate 1 deflecting in the first direction can be improved.

[0098] It should be understood that the diffusion plate 1 of the embodiment of the present invention is applied to the polarized optical system of the mirror cabinet lighting device. The values of θ n and θ1 are different, and the deflection angles are different. Different deflection angles in different environments can be designed according to actual needs, so as to adjust the values of θ n and θ1. For the scenario of the bathroom space, their value ranges can be the following numerical ranges:

[0099] The value range of w is 30 mm to 50 mm, the value range of w1 is 5 mm to 15 mm, the value range of w2 is 25 mm to 45 mm, the value range of h is 15 mm to 25 mm, the value range of n is 30 to 70, the value range of θ1 is 25° to 35°, and the value range of β1 is 80° to 120°.

[0100] A mirror cabinet lighting device according to an embodiment of the present utility model has the following technical effects:

[0101] By providing a first inner bending protrusion 121 at the lower end of the left side wall 12 of the diffusion plate 1 and a second inner bending protrusion 131 at the lower end of the right side wall 13, and providing a first groove 211 that cooperates with and is snap-connected to the first inner bending protrusion 121 on the outer side of the left side plate 21 of the housing 2 and a second groove 231 that cooperates with and is snap-connected to the second inner bending protrusion 131 on the outer side of the right side plate 23. During assembly, after installing the internal components in the housing 2, only need to align the first inner bending protrusion 121 and the second inner bending protrusion 131 of the diffusion plate 1 with the first groove 211 and the second groove 231, and then push it in to complete the assembly. The assembly process is simple and convenient, which is beneficial to improving the assembly efficiency.
