Referring to fig. 1 to 8, the present embodiment provides a logistics terminal, which includes a box body 3 and an illumination device 1, wherein the illumination device 1 is disposed on the box body 3 to provide sufficient illumination light for the surface of the box body 3, so that a user can use the logistics terminal at night or when the natural light effect is poor.

Wherein, logistics terminal refers to the equipment that can carry out article to keep in and manage, for example: the logistics terminal can be an express cabinet and is used for storing express packages. In addition, the logistics terminal can also be based on the Internet of things and has an intelligent express cabinet for identifying, tracking and monitoring articles.

Here, it should be noted that "the lighting device 1 is disposed on the box 3", which should be understood in a broad sense, that is, it should be understood that: the lighting device 1 may be disposed on the top of the box 3, or may be disposed on the side or bottom of the box 3, as shown in fig. 1, and at this time, the light emitting direction of the lighting device 1 is adjusted accordingly, so that the light is always irradiated on the surface of the box 3.

In some preferred embodiments of the present invention, the lighting device 1 is disposed on the top of the box 3, which facilitates the installation of the lighting device 1 and provides a good lighting effect for the box 3.

Next, with continued reference to fig. 1, the structure of the case 3 will be described.

As shown in fig. 1, a plurality of storage compartments 31 are provided in the case 3, and the storage compartments 31 divide the inner space of the case 3 into a plurality of independent receiving spaces for storing articles. It will be appreciated that the storage compartment 31 may also be provided with a cover plate on the surface thereof, the cover plate being rotatable about a rotation shaft fixed to the case 3 to open or close the storage compartment for storage or for a user to take out the articles stored therein.

In addition, when the commodity circulation terminal was intelligent express delivery cabinet, can also be provided with operating panel on the box 3, user's accessible operating panel selects to open or close different matter storage lattice 31.

It should be noted that fig. 1 is a schematic structural view of the logistics terminal from a front view, and the rectangular block to which the storage compartment 31 is pointed in fig. 1 is one of the plurality of storage compartments on the box 3, that is, the rest of the rectangular blocks which are not explicitly marked in fig. 1 all represent one storage compartment. Further, the storage compartments 31 may have different volumes, that is, different storage compartments 31 may have the same volume or different volumes, and as a possible design of the storage compartments 31, referring to fig. 1, the height of the storage compartment 31 near the middle of the box 3 in the vertical direction is smaller so as to store small-volume articles, and the height of the storage compartment 31 near the upper and lower ends of the box 3 in the vertical direction is higher so as to store large-volume articles.

Further, a plurality of cases 3 may be arranged in parallel to form a combined case, thereby increasing the capacity of the logistics terminal.

Next, the structure of the lighting device 1 will be described with reference to fig. 2.

As shown in fig. 2, the lighting device 1 includes a light source 11, a transparent lamp housing 12, and a light guide plate 13, the light guide plate 13 is located on the light outgoing side of the light source 11, the transparent lamp housing 12 is covered on the light source 11, the transparent lamp housing 12 has an emission curved surface 121 facing the light guide plate 13, and the projection of the light source 11 on the light guide plate 13 is located within the projection of the emission curved surface 121 on the light guide plate 13.

The curvature of the emitting curved surface 121 is obtained by optical design after considering the light emitting angle expansion range, and the light enters the transparent lampshade 12 from the light source 11, continues to spread forward to reach the emitting curved surface 121, and generates refraction phenomenon when being emitted out after passing through the emitting curved surface 121, so that part of the light is deflected to the direction far away from the light center area, and the light emitting angle is increased. Meanwhile, it can be understood that when the light source 11 is a point light source or a point light source approximate thereto, the central light intensity is reduced and the edge light intensity is increased due to more light deflected outward, thereby also increasing the light emitting uniformity of the light source 11. For example, as shown in fig. 4, the curved emission surface 121 may be a curved surface protruding toward the light guide plate 13, and further, the curved emission surface 121 may be a spherical surface protruding toward the light guide plate 13.

The transparent lampshade 12 may be any light-guiding cover structure, for example: the transparent cover 12 may be in the form of a semi-spherical, cubic, cylindrical, etc. regular shape, or in the form of other irregular shapes. In consideration of the overall light-emitting uniformity of the transparent lampshade 12, the present embodiment preferably uses the transparent lampshade 12 in a semi-spherical shape to ensure that the light intensity of the light emitted from the light source 11 in the circumferential direction around the transparent lampshade 12 is consistent.

In addition, the transparent cover 12 may be mainly made of any light-conductive material. Preferably, the transparent cover 12 may be composed primarily of high light conductivity materials, such as: the transparent lamp cover 12 may be mainly formed of an acrylic member, i.e., Polymethyl Methacrylate (PMMA), Polycarbonate (PC), or optical glass, etc., thereby reducing light intensity loss caused by light passing therethrough.

Alternatively, the light source 11 may be any light-emitting device, such as: the light source 11 may be a light emitting diode, an incandescent bulb, a fluorescent tube, or the like. In consideration of the service life and the working efficiency of the light source 11, the present embodiment preferably adopts a light emitting diode capable of emitting white light as the light source 11, which not only can work for a long time and has a long service life, but also can improve the experience of the user when using the logistics terminal by emitting white light from the light source 11.

Alternatively, the light guide plate 13 may be any light-conductive flat plate, such as: the light guide plate 13 may have a regular shape such as a rectangular shape or an oblong shape. The light guide plate 13 may be mainly composed of a light conductive material such as glass, light transmissive plastic, or the like. When the light source 11 with high luminous power is adopted, in order to relieve the stimulation of the light source 11 to human eyes, the light guide plate 13 can also be mainly composed of semitransparent or opaque light guide materials, in addition, a frosted structure can be arranged on the surface of the light guide plate 13 facing to the outer side, so that light rays are further dispersed, the light rays emitted by the light guide plate 13 are uniform and soft, and the stimulation to human eyes is small.

Referring to fig. 5, the present embodiment further provides another transparent lamp cover 12, specifically, the emission curved surface 121 in the transparent lamp cover 12 may further include a first curved surface 1211 and a second curved surface 1212, the first curved surface 1211 protrudes outward (light emitting direction), the light emitting angle of the light source 11 is increased through refraction, the second curved surface 1212 is located at the top of the transparent lamp cover 12 and is recessed in a direction away from the light guide plate, and after the curvature is optically designed, the central light intensity of the light source 1 can be reduced, so that the light is more uniform and soft.

In addition, it should be noted that, the projection of the light source 11 on the light guide plate 13 is located in the projection of the curved emission surface 121 on the light guide plate 13, so that the light emitted from the light source 11 can certainly pass through the curved emission surface 121, that is, the curved emission surface 121 of the transparent lamp cover 12 can completely cover the light-emitting end face of the light source 11. In this embodiment, it is not required whether the light source 11 is located in the transparent lampshade 12, as long as the light emitted from the light source 11 can pass through the curved emission surface 121. In a possible design, the transparent lampshade 12 can be directly covered on the light source 11 and located on a propagation path of light emitted by the light source 11, and the light enters the transparent lampshade 12 after propagating for a certain distance in space, continues to propagate and is emitted from the emission curved surface 121; in another possible design, the light source 11 is also arranged inside the transparent cover 12, so as to ensure that all the light rays can enter the transparent cover 12 and then be emitted from the curved emission surface 121 and spread towards the light guide plate 13.

Referring to fig. 3, fig. 3 is a schematic diagram of an optical path of the light source observed from a side view after the lighting device 1 is cut, which is equivalent to a sectional view of a side surface of the light guide plate 13, wherein a vertical line segment on the rightmost side indicates a position of the light guide plate 13, and the light source 11 is on the leftmost side. A solid line between the light source 11 and the light guide plate 13 indicates a light path when the light source 11 is not covered with the transparent cover 12, and a dotted line between the light source 11 and the light guide plate 13 indicates a light path after the light source 11 is covered with the transparent cover 12. It can be seen that the light source 11 is located at the center of the light guide plate 13 at the projection position of the light guide plate 13, and when the transparent lamp cover 12 is not covered, since the light emitting angle of the light source 11 is limited, the light only passes through the center area of the light guide plate 13, and no light passes through the upper and lower edge areas of the light guide plate 13, thereby forming the shadow area 4.

After the transparent lampshade 12 is added, the light emitting angle is increased, and the area of the light guide plate 13 for receiving light is increased, so that the light can pass through the whole area of the light guide plate 13, and the shadow area 4 is eliminated when the transparent lampshade 12 is not installed.

The commodity circulation terminal that this embodiment provided includes box 3 and lighting device 1, lighting device 1 sets up on box 3, establish the light that light source 11 sent through the cover at the transparent lamp shade 12 on light source 11, and be provided with emission curved surface 121 on transparent lamp shade 12 surface, the light that light source 11 sent enters into in the transparent lamp shade 12, and then the emission curved surface 121 by transparent lamp shade 12 jets out, light can take place the refraction when through emission curved surface 121, and then luminous angle has been enlarged, the regional area increase of receiving light on the light guide plate 13, lighting device 1 has improved the illuminating effect to box 3.

Please continue to refer to fig. 4. In order to further increase the light emitting angle of the light source 11, a transparent protrusion 1213 may be optionally further disposed on the emission curved surface 121. When the light emitted from the light source 11 propagates in the transparent lampshade 12, a part of the light is emitted from the emission curved surface 121, and the other part of the light is emitted from the transparent protrusion 1213, and by the arrangement of the transparent protrusion 1213, the surface structure of the emission curved surface 121 is changed, so that more light can be refracted to different directions, and the light emitting angle of the light source 11 can be further increased.

It should be noted that, the materials used for the transparent protrusion 1213 and the transparent lampshade 12 may be substantially the same, and in a possible design, the transparent protrusion 1213 is formed on the surface of the transparent lampshade 12, and both are integrally formed by injection molding, which can effectively improve the production and processing efficiency.

Illustratively, the shape of the transparent protrusions 1213 may be regular shapes such as truncated pyramid, truncated cone, and hemispherical, but the shape of the transparent protrusions 1213 may be irregular shapes.

In the present embodiment, the transparent protrusions 1213 extend from the edges of the emission curved surface 121 toward the middle. Such a mode of arrangement is convenient for production and processing, especially when transparent protruding portion 1213 and transparent lamp shade 12 adopt injection moulding processing integrated into one piece, this kind of distribution mode is of value to the die sinking angle, the mould structural design of being convenient for. In addition, the volume of the transparent protrusions 1213 is increased, so that more light is emitted through the transparent protrusions 1213, and the area of the light guide plate 13 receiving the light is further increased, thereby further improving the illumination effect.

The present embodiment is not limited to a specific extending direction of the transparent protrusions 1213 as long as the light emission angle can be increased. Alternatively, taking the case where the bottom surface of the transparent cover 12 is placed horizontally as an example, the transparent protrusions 1213 may extend upward in the vertical direction; alternatively, the inclined part may extend upward at an angle to the vertical direction.

Please refer to fig. 7. Further, the transparent protrusions 1213 are triangular in cross section perpendicular to the extending direction. When the cross-section is triangular, the transparent protrusion 1213 is equivalent to a prism-shaped structure composed of two intersecting planes, and the light emission angle can be further increased by utilizing the characteristic of good polarization performance of the prism.

Note that, in the present embodiment, the cross section of the transparent protrusions 1213 in the direction perpendicular to the extending direction is not limited to a triangle, and the cross section may take other shapes, for example: the cross section may also be in the shape of a regular circle, semi-ellipse, rectangle, or other irregular shapes. Alternatively, the transparent protrusions 1213 are plural, and the plural transparent protrusions 1213 are arranged at intervals on the emission curved surface 121. The single transparent protrusion 1213 may already function to increase the light emission angle, and by providing a plurality of transparent protrusions 1213, the light emission angle of the light source 11 may be further increased.

Alternatively, the plurality of transparent protrusions 1213 may be arranged at uniform intervals, for example: the transparent protrusions 1213 in fig. 5 and 6 are uniformly spaced along the central axis of the transparent cover 12, so that the light emitting angle is increased and the uniformity of the light emitted from the light source 11 is further improved. Alternatively, the plurality of transparent protrusions 1213 may be arranged at uneven intervals. This embodiment is not limited in this regard.

When light enters a medium with a higher refractive index and enters a medium with a lower refractive index, the light is not refracted but reflected when the incident angle is larger than a certain critical angle, which is a total reflection principle, the transparent convex parts 1213 are made of a material with a high refractive index, and the plurality of transparent convex parts 1213 are arranged, so that after the light enters the transparent lampshade 12, the normal included angle between part of the light and the transparent convex parts 1213, namely the incident angle is larger than the critical angle, and the reflected light is diffused towards each angle until the reflection condition is destroyed and then is emitted from the surface of the emission curved surface 121 or the surface of the transparent convex parts 1213. By providing the transparent protrusions 1213 having different densities and sizes, the light source 11 can emit light uniformly and the light emission angle can be increased.

In addition, the transparent lamp cover 12 can protect the light source 11 from being damaged by the light source 11 contacting with an external object.

Alternatively, the mounting groove 124 may be a groove structure disposed at any position of the transparent lampshade 12 facing away from the light guide plate 13, for example: the cross section of the mounting groove 124 along the direction perpendicular to the light emitting direction may be a regular shape such as a circle, a rectangle, an ellipse, etc., or the cross section of the mounting groove 124 along the direction perpendicular to the light emitting direction may be other irregular shapes. In order to make the light emitted from the light source 11 through the transparent cover 12 more uniform, the mounting groove 124 may be disposed at a central position of the transparent cover 2.
