DETAILED DESCRIPTION

[0022] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work are within the scope of protection of the present application.

[0023] Please refer to Figure 1 The lighting device 100 provided by the embodiments of the present application can be used in a lighting application environment or used to create a light atmosphere in an application environment. In the embodiments, the lighting device 100 can be fixedly installed on a building or other structure in the application environment, or can be movably arranged in the application environment according to actual needs. For example, the lighting device 100 can be fixedly installed on a wall or ceiling in the application environment, or can be freely moved in the application environment to change the irradiation object of the lighting device 100.

[0024] In the embodiment, the lighting device 100 comprises a housing 10 and a light emitting module 20. In the embodiment, the housing 10 is substantially hollow, and the housing 10 is provided with a receiving space 13, and the light emitting module 20 is arranged in the receiving space 13, and the receiving space 13 can also be used to accommodate other components of the lighting device 100. In the embodiment, part of the housing 10 is a light-transmitting structure, and the light emitted by the light emitting module 20 can be transmitted through part of the housing 10 and conducted to the outside of the housing 10. As an example, the housing 10 comprises a housing body 14 and a lampshade 15, the housing body 14 is an open structure, the lampshade 15 is connected to the housing body 14 and covers the opening of the housing body 14, and the lampshade 15 cooperates with the housing 10 to define the receiving space 13. The lampshade 15 is a light-transmitting structure, the light emitting module 20 is arranged in the receiving space 13, and the light emitting side of the light emitting module 20 is arranged towards the lampshade 15. The lampshade 15 allows the light to be conducted out and has the effect of homogenizing the light, so that the light conducted out of the receiving space 13 is relatively uniform, and the light forms a relatively uniform light effect on the wall or other light receiving surface.

[0025] Please refer to Figure 1 and Figure 2 In the embodiment, the housing 10 is provided with a first ventilation area 11, and the first ventilation area 11 is located on one side of the light emitting module 20. The first ventilation area 11 is used to communicate the receiving space 13 with the external environment of the housing 10, so that air can flow between the receiving space 13 and the external environment. It should be understood that the light emitting module 20 may generate heat when working, and the air can carry the heat out of the receiving space 13 during the flow process, so as to reduce the temperature at the light emitting module 20, avoid damage to the light emitting module 20 due to high temperature of the light emitting module 20, and reduce the temperature in the receiving space 13.

[0026] In the embodiment, the light emitting module 20 can comprise at least one LED lamp bead. The LED lamp bead has the advantage of high conversion of electric energy into light energy, and the conversion rate can be as high as 90%, and the generated heat is less, which can avoid high temperature at the light emitting module 20. In some embodiments, the number of LED lamp beads is multiple, and the multiple LED lamp beads are divided into multiple groups, and the multiple LED lamp beads in each group are integrated into an LED light emitting panel. The LED light emitting panel has a large light output and a strong light intensity, which improves the lighting effect or atmosphere effect of the lighting device 100. In the embodiment, the light color of each LED lamp bead or the light color of each LED light emitting panel can be set according to actual needs, such as red, yellow, green, white, warm white, etc.

[0027] Please refer to Figure 2 and Figure 3In the embodiment, the first ventilation area 11 can be provided with a plurality of ventilation units 111 arranged in the first direction A in sequence and at intervals, each of the ventilation units 111 is provided with a plurality of through holes respectively communicating with the accommodation space 13, and the plurality of through holes in each of the ventilation units 111 are arranged in the second direction B in sequence and at intervals. In the embodiment, the first direction A and the second direction B intersect each other, so that the plurality of through holes of the plurality of ventilation units 111 are distributed in an array, so that the plurality of through holes are more concentrated and more uniformly distributed on the first ventilation area 11, so as to effectively take away the heat at the light emitting module 20 and the heat in the accommodation space 13 through air flow, and quickly reduce the temperature at the light emitting module 20 and the temperature in the accommodation space 13, so as to realize effective ventilation of the first ventilation area 11. In the embodiment, the first direction A and the second direction B are perpendicular to each other, and the plurality of ventilation units 111 are arranged in a straight line, and the plurality of through holes in each of the ventilation units 111 are arranged in a straight line. In other embodiments, the plurality of through holes in each of the ventilation units 111 can be arranged in a curve.

[0028] In the embodiment, the plurality of through holes at least include a plurality of first through holes 1111 and a plurality of second through holes 1112, and the ventilation area of the first through hole 1111 is different from that of the second through hole 1112. Specifically, the maximum aperture size of the first through hole 1111 in the first direction A is the same as that of the second through hole 1112 in the first direction A, and the maximum aperture size of the first through hole 1111 in the second direction B is greater than that of the second through hole 1112 in the second direction B, so that the ventilation area of the first through hole 1111 is greater than that of the second through hole 1112.

[0029] In summary, under the arrangement of the embodiment, there is a continuous shell 10 structure between the two adjacent ventilation units 111, which can ensure the strength of the structure of the first ventilation area 11, and the first through hole 1111 with a larger degree of hollowing and the second through hole 1112 with a smaller degree of hollowing are combined to avoid the structure of the first ventilation area 11 being relatively weak due to the ventilation area of the through hole being generally large; and the effective ventilation area (the sum of the ventilation areas of the plurality of through holes) of the first ventilation area 11 is large to improve the ventilation capacity, and the effective ventilation area of the first ventilation area 11 is small due to the ventilation area of the through hole being generally small, so that the shell provided by the embodiment can not only ensure better ventilation effect, but also take into account higher structural strength.

[0030] In the embodiment, the plurality of first through holes 1111 include at least one of an oblong hole or a waist-shaped hole; and the plurality of second through holes 1112 include at least one of a round hole, a square hole, and a triangular hole.

[0031] In some embodiments, the shell 10 is produced by an injection molding process. In conventional technology, at least one welding line is formed around each through hole when the plastic part is formed, which seriously affects the structural strength of the shell 10, and the larger the ventilation area of the through hole, the lower the structural strength of the edge structure of the through hole. However, in the present embodiment, the combination of the through hole with a large ventilation area and the through hole with a small ventilation area can ensure that the first ventilation area 11 still has a large effective ventilation area, and can also reduce the number of through holes with a large ventilation area, avoid too many welding lines, and thus improve the structural strength of the shell 10.

[0032] Please refer to Figure 3 In the present embodiment, the plurality of first through holes 1111 and the plurality of second through holes 1112 in each ventilation unit 111 are arranged alternately. In the present embodiment, the ventilation area of the first through hole 1111 is larger than that of the second through hole 1112, and therefore the edge structural strength of the second through hole 1112 is greater than that of the first through hole 1111. In the present embodiment, each first through hole 1111 is provided with at least one second through hole 1112 at both ends in the second direction B, which on the one hand disperses the arrangement of the first through holes 1111 to avoid the aggregation of the first through holes 1111 leading to a decrease in the structural strength of the shell 10, and on the other hand the edge structure of the second through hole 1112 is relatively stable and can play a role in strengthening the edge structural strength of the first through hole 1111, thereby improving the overall structural strength of the shell 10. In the present embodiment, one second through hole 1112 is provided between two adjacent first through holes 1111 to avoid too many second through holes 1112 reducing the effective ventilation area, and also to arrange the plurality of through holes in a certain regular pattern, so that the arrangement of the through holes has a certain aesthetic sense.

[0033] In the present embodiment, the maximum hole diameter of the first through hole 1111 in the first direction A is substantially equal to the maximum hole diameter of the second through hole 1112 in the first direction A, so that there is a continuous shell 10 structure between two adjacent ventilation units 111, thereby improving the structural strength of the first ventilation area 11. In the present embodiment, the maximum hole diameters of the first through hole 1111 and the second through hole 1112 in the first direction A can be considered the same within a reasonable error range. The error value / the maximum hole diameter of the second through hole 1112 in the first direction A is taken as an error ratio, and in the case where the error ratio is less than or equal to 25%, the maximum hole diameters of the first through hole 1111 and the second through hole 1112 in the first direction A are considered the same. For example, the maximum hole diameter of the first through hole 1111 in the first direction A is 3 mm, the maximum hole diameter of the second through hole 1112 in the first direction A is 2.5 mm, the error value is 0.5 mm, and the error ratio is 20% and less than 25%, so the maximum hole diameters of the first through hole 1111 and the second through hole 1112 in the first direction A are considered the same.

[0034] In the embodiment, the first through hole 1111 is a waist-shaped hole, and the second through hole 1112 is a circular hole. The waist-shaped hole and the circular hole are conventional hole types, and the mold is easy to manufacture under the injection molding process. Under the punch or drilling and milling process, the operation is simple, the requirement for the tool is low, and the production cost is reduced. In the embodiment, the maximum hole diameter size of the waist-shaped hole is the maximum hole diameter size of the waist-shaped hole in the second direction B. It can be understood that the hole wall of the waist-shaped hole extends along the second direction B. In other embodiments, the through hole can be a square hole or an irregular hole type. The relationship between the maximum hole diameter size of the through hole and the maximum hole diameter size of the through hole in the second direction B is related to the hole type of the through hole, which is not described in detail here.

[0035] In the embodiment, the hole diameter of the second through hole 1112 ranges from greater than or equal to 1 mm to less than or equal to 2 mm, for example, 1 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, or 2 mm. The second through hole 1112 is small, and the edge structure strength of the second through hole 1112 is high. The second through hole 1112 has less effect on the structural strength of the first ventilation area 11. In the embodiment, the second through hole 1112 is a circular hole, and the second through hole 1112 has one hole diameter size, and the ventilation area of the second through hole 1112 can be directly calculated. In other embodiments, the second through hole 1112 is a square hole or an irregular hole type, and the second through hole 1112 has multiple hole diameter sizes, and the multiple hole diameter sizes are all within the range of [1 mm, 2 mm]. In the embodiment, the first ventilation area 11 is provided with multiple second through holes 1112, and the multiple second through holes 1112 can all be one hole type or have multiple hole types.

[0036] In the embodiment, the minimum distance between the two adjacent through holes in each ventilation unit 111 ranges from greater than or equal to 2 mm to less than or equal to 3 mm, for example, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or 3 mm. In the embodiment, the distance between the through holes should not be too large to avoid a small effective ventilation area, and the distance between the through holes should not be too small to avoid a significant reduction in the structural strength of the shell 10. In the embodiment, based on the product type of the lighting device 100, the size of the through hole is generally small, and it is more appropriate to limit the minimum distance between the two adjacent through holes to between 2 mm and 3 mm.

[0037] Please refer to Figure 3 and Figure 4In the embodiment, the plurality of ventilation units 111 include the adjacent first ventilation unit 1113 and the second ventilation unit 1114, and the first ventilation unit 1113 and the second ventilation unit 1114 are arranged side by side in the first direction A. In the embodiment, the second through hole 1112 in the first ventilation unit 1113 and the second through hole 1112 in the second ventilation unit 1114 are arranged staggered in the first direction A, so that the structure with greater structural strength and the structure with smaller structural strength are arranged side by side in the first direction A, to improve the structural strength of the whole shell 10. Specifically, the above-mentioned "staggered arrangement" can be understood as that the directions defined by the second through hole 1112 in the first ventilation unit 1113 and the second through hole 1112 in the second ventilation unit 1114 are different from the first direction A, and the directions defined by the two second through holes 1112 can refer to the directions defined by the lines between the geometric centers of the two second through holes 1112. In the embodiment, in the case that the second through hole 1112 in the first ventilation unit 1113 and the second through hole 1112 in the second ventilation unit 1114 are arranged staggered in the first direction A, the first through hole 1111 in the first ventilation unit 1113 and the first through hole 1111 in the second ventilation unit 1114 are also arranged staggered in the first direction A, and based on the larger ventilation area of the first through hole 1111, the two first through holes 1111 of the adjacent two ventilation units 111 can be partially opposite but not completely opposite in the first direction A.

[0038] In some embodiments, there are cases that the remaining area of the end of the first ventilation unit 1113 in the second direction B is insufficient to arrange the first through hole 1111 with larger ventilation area, and the second through hole 1112 can be arranged in the remaining area; the remaining area of the end of the second ventilation unit 1114 in the second direction B is insufficient to arrange the first through hole 1111 with larger ventilation area, and the second through hole 1112 can be arranged in the remaining area. In such cases, there are cases that the second through hole 1112 in the first ventilation unit 1113 and the second through hole 1112 in the second ventilation unit 1114 are arranged side by side in the first direction A.

[0039] Please refer to Figure 5 In the embodiment, in order to ensure the heat dissipation effect of the lighting device 100, the lighting device 100 further includes a heat dissipation module 30, and the heat dissipation module 30 is connected to the light-emitting module 20 and can promote heat dissipation of the light-emitting module 20. In the embodiment, the heat dissipation module 30 is arranged between the first ventilation area 11 and the light-emitting module 20, which is conducive to heat exchange or heat dissipation between the heat dissipation module 30 and the external air. In the embodiment, the heat dissipation module 30 can include at least one of a fin heat dissipation piece, a fan, and a condenser water pipe.

[0040] In the embodiment, the heat dissipation module 30 comprises a fin heat dissipation element, and the fin heat dissipation element comprises a plurality of heat dissipation fins 311. In the embodiment, the plurality of heat dissipation fins 311 are arranged at intervals, and two adjacent heat dissipation fins 311 define a heat dissipation space 3111. Each heat dissipation fin 311 extends towards the first ventilation area 11 relative to the light emitting module 20, and the extension direction of the heat dissipation fin 311 relative to the light emitting module 20 is consistent with the axial direction of the through hole. In the arrangement of the embodiment, the external air is facilitated to flow to the plurality of heat dissipation spaces 3111, so as to quickly carry away the heat in the heat dissipation spaces 3111. In the embodiment, the extension direction of the heat dissipation fin 311 relative to the light emitting module 20 can be the same as the axial direction of the through hole, or can have a certain deviation.

[0041] Please refer to Figure 2 and Figure 5 In the embodiment, the lighting device 100 further comprises two second ventilation areas 12, and the two second ventilation areas 12 are respectively located on the two sides of the first ventilation area 11. The accommodation space 13 is in communication with the outside through the second ventilation area 12, so as to improve the communication degree of the accommodation space 13 with the external environment, facilitate the circulation of air, and promote the dissipation of heat. In the embodiment, the heat dissipation module 30 is located between the two second ventilation areas 12, so that the heat dissipation module 30 is substantially surrounded by the two second ventilation areas 12 and the first ventilation area 11. After the air enters the accommodation space 13, the air quickly contacts the heat dissipation module 30, so as to effectively absorb the heat of the heat dissipation module 30.

[0042] Please refer to Figure 5 In the embodiment, the plurality of heat dissipation fins 311 of the heat dissipation module 30 are arranged at intervals in sequence, and the second ventilation area 12 comprises a plurality of third through holes 121. The axial line of the third through hole 121 is parallel to the plane in which the heat dissipation fin 311 is located. In the arrangement of the embodiment, the external air is facilitated to flow between two adjacent heat dissipation fins 311, so as to quickly carry away the heat accumulated in the heat dissipation fin 311. In other embodiments, the axial line of the third through hole 121 can also intersect the plane in which the heat dissipation fin 311 is located. In the intersecting state, the included angle between the axial line of the third through hole 121 and the plane in which the heat dissipation fin 311 is located ranges from 0° to 5°, such as 1°, 2°, 3°, 4° or 5°. In the embodiment, the third through hole 121 can be arranged in the same manner as the first ventilation area 11, that is, at least two heat dissipation holes with different ventilation areas are selected, so that the second ventilation area 12 has strong ventilation capacity and ensures the structural strength of the second ventilation area 12.

[0043] In the embodiment, the lighting device 100 comprises a housing 10 and a light emitting module 20. The housing 10 is provided with a receiving space 13, and the light emitting module 20 is arranged in the receiving space 13. The housing 10 is provided with a first ventilation area 11, and the first ventilation area 11 is located at one side of the light emitting module 20. The first ventilation area 11 is provided with a plurality of ventilation units 111, and the plurality of ventilation units 111 are arranged in sequence and spaced apart along a first direction A. Each ventilation unit 111 is provided with a plurality of through holes respectively communicating with the receiving space 13, and the plurality of through holes of each ventilation unit 111 are arranged in sequence and spaced apart along a second direction B. In the embodiment, the first direction A intersects the second direction B, so that the plurality of through holes of the plurality of ventilation units 111 are distributed in an array, so that the plurality of through holes are more concentrated and more uniformly distributed on the first ventilation area 11, so as to effectively take away the heat at the light emitting module 20 and the heat in the receiving space 13 through air flow, and quickly reduce the temperature at the light emitting module 20 and the temperature in the receiving space 13, so as to realize effective ventilation of the first ventilation area 11.

[0044] In the embodiment, the plurality of through holes comprise a plurality of first through holes 1111 and a plurality of second through holes 1112, and the ventilation area of the first through hole 1111 is different from the ventilation area of the second through hole 1112. Specifically, the maximum aperture size of the first through hole 1111 in the first direction A is the same as the maximum aperture size of the second through hole 1112 in the first direction A, and the maximum aperture size of the first through hole 1111 in the second direction B is greater than the maximum aperture size of the second through hole 1112 in the second direction B, so that the ventilation area of the first through hole 1111 is greater than the ventilation area of the second through hole 1112.

[0045] In summary, under the arrangement of the embodiment, there is a continuous housing 10 structure between the two adjacent ventilation units 111, which can ensure the strength of the structure of the first ventilation area 11. The first through hole 1111 with a larger degree of hollowing and the second through hole 1112 with a smaller degree of hollowing are combined to avoid the structure of the first ventilation area 11 being relatively weak due to the ventilation area of the through hole being generally large. The effective ventilation area (the sum of the ventilation areas of the plurality of through holes) of the first ventilation area 11 is large to improve the ventilation capacity, and the effective ventilation area of the first ventilation area 11 is small due to the ventilation area of the through hole being generally small. Therefore, the housing provided by the embodiment can not only ensure better ventilation effect, but also take into account higher structural strength.
