The embodiment of the present application provides a linear lighting module 100. Fig. 1 is a schematic view of a linear illumination module according to a first embodiment of the present application. Fig. 2 is a cross-sectional view of the linear lighting module of fig. 1. Fig. 1 and 2 are schematic views of a first embodiment of the linear lighting module 100 provided in the present application. The linear illumination module 100 will be described with reference to the linear illumination module 100 shown in fig. 1 and 2.

As shown in fig. 1 and 2, the linear illumination module 100 includes a light source assembly 10 and a protective member 20. The protection member 20 has a receiving cavity 201 and a light-emitting portion 21 for enclosing the receiving cavity 201, the light-emitting portion 21 has a first lens layer 211 facing the receiving cavity 201 and a second lens layer 212 facing away from the receiving cavity 201, and a gap 202 for mixing light is formed between the first lens layer 211 and the second lens layer 212. The light source module 10 is accommodated in the accommodating cavity 201, and the light source module 10 includes a light source substrate 11 and light emitting elements 12. The light source substrate 11 is mounted in the receiving cavity 201 and has a bearing surface 101 facing the first lens layer 211, the light emitting elements 12 are disposed on the bearing surface 101 and electrically connected to the light source substrate 11, the light emitting elements 12 are arranged at intervals along the extending direction, and any two adjacent light emitting elements 12 are partially displaced in a displacement direction perpendicular to the extending direction.

In this case, "any two adjacent light emitting elements 12 are partially displaced in a displacement direction perpendicular to the extending direction", that is, orthographic projections of any two adjacent light emitting elements 12 in the second direction Z partially overlap. It is also understood that the light emitting element 12 is disposed facing the first lens layer 211 and emits light toward the first lens layer 211, and the light emitted from the light emitting element 12 is emitted after passing through the first lens layer 211, the gap 202, and the second lens layer 212 in this order.

Compared with the prior art, the linear lighting module of the present application is provided with a plurality of light-emitting elements 12 in the partial dislocation arrangement in the dislocation direction, so that the distance between two adjacent light-emitting elements 12 in the extending direction is reduced on the premise of satisfying the safety distance of the wiring, and the arrangement density of the light-emitting elements 12 in the extending direction is increased, thereby preventing the linear lighting module 100 from having granular sensation (i.e. the linear lighting module 100 is provided with alternately arranged bright and dark regions in the extending direction), and further improving the overall power of the light source assembly 10 and increasing the brightness. Meanwhile, the light emitting portion 21 is configured to have a double-layer light distribution structure including the first lens layer 211, the gap 202 and the second lens layer 212, so that the light emitted by the light source assembly 10 is emitted through the first lens layer 211, the gap 202 and the second lens layer 212, and the light distribution is performed twice, thereby solving the problem of deviation of the optical axes between the light emitting elements 12 due to the staggered arrangement of the light emitting elements 12, preventing the linear illumination module 100 from having bright and dark areas along the staggered direction, making the light emitted by the linear illumination module 100 uniform, and improving the light efficiency, referring to fig. 4 specifically. Moreover, first lens layer 211 with second lens layer 212 is for light source subassembly 10 provides double-deck protection, and the protection effect is better, can improve linear lighting module 100 is in the stability of installation with the transportation, avoids appearing the risk that excessive deformation was pressed wounded. Moreover, the gap 202 can reduce the total weight of the protector 20 while achieving the light mixing effect.

In the present application, the extending direction of the linear illumination module 100 (hereinafter referred to as the first direction X), i.e., the extending direction of the receiving cavity 201, the extending direction of the light source assembly 10, and the extending direction of the bearing surface 101, is described. The light emitting direction (hereinafter referred to as the second direction Y) is substantially the thickness direction of the linear illumination module 100, that is, the width direction of the light emitting portion 21, the accommodating cavity 201, the light source assembly 10, and the carrying surface 101. The offset direction (hereinafter referred to as the third direction Z) is substantially a width direction of the linear illumination module 100, that is, a width direction of the accommodating cavity 201, the light source assembly 10, and the bearing surface 101.

Specifically, the first direction X may be a straight line, or may also be a curved line or a broken line. Specifically, referring to fig. 1, in the present embodiment, the linear illumination module 100 is an elongated shape as a whole. In other embodiments, the linear lighting module 100 may be configured as a flexible lighting module and may be joined end-to-end to form a ring-shaped structure. In this case, the first direction X is a plurality of broken lines or curved lines. For example, in some illustrative scenarios, the linear lighting module 100 may enclose a closed rectangle for decorating the outer periphery of the ceiling lamp.

Referring to fig. 2, 5 and 6, the light source substrate 11 is a plate-shaped member. The light source substrate 11 has a length direction, a width direction, and a thickness direction, and the length direction, the width direction, and the thickness direction are respectively consistent with the first direction X, the third direction Z, and the second direction Y of the linear lighting module.

Referring to fig. 2 and fig. 3, in addition to the carrying surface 101 for carrying the light emitting element 12, the light source substrate 11 further has a mounting surface 102 opposite to the carrying surface 101 in a thickness direction (i.e., the second direction Y), and the mounting surface 102 is used for attaching and fixing the light source substrate 11 and the inner side wall of the accommodating cavity 201. That is, the light source substrate 11 is fixedly mounted on the inner side wall of the accommodating cavity 201 through the mounting surface 102. In one embodiment, the mounting surface 102 may be adhesively secured 22 to the inner sidewall of the receiving cavity 201 by an adhesive.

However, the present application does not substantially limit the connection manner between the light source substrate 11 and the accommodating cavity 201. For example, in some other embodiments, a groove extending along the first direction X may be formed on an inner sidewall of the receiving cavity 201, and both side edges of the light source substrate 11 in the third direction Z are disposed in the groove to fix the light source substrate 11 in the receiving cavity.

Referring to fig. 5, in particular, in the embodiment of the present application, the light source substrate 11 is a strip shape as a whole, and the carrying surface 101 and the mounting surface 102 are rectangular planes respectively.

In particular, in the embodiment of the present application, the light source substrate 11 may have a rectangular plate shape. The bearing surface 101 and the mounting surface 102 are each rectangular planes. The rectangular structural form is beneficial to splicing the light source substrates 11, so that splicing processing is facilitated, the utilization rate of the light source substrates 11 is increased, and the production cost is reduced. However, the light source substrate 11 may have another shape and structure other than the above embodiments. The shape and material of the light source substrate mentioned in the present application are not particularly limited.

In a preferred embodiment, the light source substrate 11 is an aluminum substrate. Thus, the heat dissipation effect of the light source substrate 11 is improved. However, the embodiment of the light source substrate 11 described in the present application is not limited thereto. For example, in other embodiments, the light source substrate 11 may also be a PCB, and may also be another circuit substrate.

Illustratively, the light emitting elements 12 extend along the third direction Z and are uniformly spaced along the first direction X. Further, the plurality of light emitting elements 12 are identical in shape.

Based on the above embodiment, the plurality of light emitting elements 12 includes a plurality of sets of light emitting elements. The plurality of groups of light emitting element groups are alternately arranged along the first direction X in sequence, and the adjacent light emitting element groups are staggered in the third direction Z. Each of the light emitting element groups includes a plurality of the light emitting elements 12 arranged at equal intervals along the first direction X and at the same positions along the third direction Z.

Referring to fig. 2 and fig. 6, each of the light emitting elements 12 has an extension length D in the third direction Z, and a maximum misalignment distance D between two adjacent light emitting elements 12 in the second direction Z is ₁ Said maximum dislocation distance D ₁ Satisfies the following conditions: 0.5D is less than or equal to D ₁ Less than or equal to 1D. By defining said maximum misalignment distance D ₁ And the dislocation distance of two adjacent groups of light-emitting element groups in the third direction Z meets the wiring requirement.

Referring to fig. 6, in the present embodiment, the plurality of light emitting elements 12 includes a first light emitting element group and a second light emitting element group. The first light emitting element group includes a plurality of first light emitting elements 121, and the second light emitting element group includes a plurality of second light emitting elements 122.

Wherein the first light emitting element 121 and the second light emitting element 122 emit light of different colors. Illustratively, the first light emitting element 121 is a yellow light emitting element, and the second light emitting element 122 is a blue light emitting element.

Referring to fig. 6, in the first direction X, a pitch of any two adjacent light emitting elements in the first direction X is C, where the pitch C satisfies: c is more than or equal to 0.5mm and less than or equal to 1.5mm. Specifically, in this embodiment, the distance C between the adjacent first light emitting elements 121 and the adjacent second light emitting elements 122 satisfies: c is more than or equal to 0.75mm and less than or equal to 1.5mm. Preferably, the distance C between adjacent first light emitting elements 121 and second light emitting elements 122 is 0.75mm.

Based on the above embodiment, the color temperatures of the adjacent light emitting element groups are different or the same.

Illustratively, the color temperatures of the adjacent light emitting element groups are different. I.e. the first light emitting element 121 and the second light emitting element 122 are not identical. In the first direction X, the color temperatures of any two adjacent first light emitting elements 121 and second light emitting elements 122 are the same, and the distance between the two adjacent first light emitting elements 121 and second light emitting elements 122 is C, where the distance C satisfies: c is more than or equal to 0.75mm and less than or equal to 1.5mm. Preferably, a pitch C between adjacent first light emitting elements 121 and second light emitting elements 122 is 0.75mm.

Similarly, if the color temperatures of the adjacent light emitting element groups are the same. That is, the color temperatures of the first light emitting element 121 and the second light emitting element 122 are the same. In the first direction X, the color temperatures of any two adjacent first light emitting elements 121 and second light emitting elements 122 are the same, and the distance between the two adjacent first light emitting elements 121 and second light emitting elements 122 is C, where the distance C satisfies: c is more than or equal to 0.5mm and less than or equal to 1mm.

Further, the color temperatures of the first light emitting element 121 and the second light emitting element 122 are different. Thus, different color temperatures and color changes can be realized by adjusting different brightness of the two color temperatures. And the shading of the first light emitting element 121 and/or the second light emitting element 122 can be realized by control. Illustratively, the color temperature of the first light emitting element 121 is 5700K, and the color temperature of the second light emitting element 122 is 2700K.

In order to control the light emitting elements 121 to emit light, a plurality of driving circuits 14 are formed on the light source substrate 11. The light emitting elements 12 in the same light emitting element group are connected to the same driving circuit 14, and different light emitting element groups correspond to different driving circuits 14.

As shown in fig. 6, in the present embodiment, the driving circuit 14 includes a first driving circuit 141 and a second driving circuit 142. Along the third direction Z, the first driving circuit 141 is located on a side of the first light emitting element group away from the second light emitting element group, and the plurality of first light emitting elements 121 are connected in parallel to the first driving circuit. The second driving circuit 142 is located at a side of the second light emitting element group away from the first light emitting element group. The plurality of second light emitting elements 122 are connected in parallel to the second driving circuit 142. Because the first light emitting element group and the second light emitting element group are arranged along the third direction Z in a staggered manner, the connecting wires between the first light emitting elements can be arranged by winding in the staggered area of the second light emitting elements, so that the distance between the light emitting elements 12 can be shortened under the condition of meeting the wiring safety standard.

In practical applications, the light emitting element 12 may be an LED light source, and may also be another type of light source, such as an EL (electroluminescence) light source.

Illustratively, a plurality of mounting bases 13 are protruded from the carrying surface 101, and the mounting bases 13 are used for mounting the light emitting elements 12. Each of the mounting bases 13 corresponds to one of the light emitting elements 12. In order to facilitate the installation of the light emitting element 12, a mounting groove is formed on the surface of the mounting base 13 away from the bearing surface 101, and the light emitting element 12 is press-mounted in the mounting groove. It is understood that, in practical implementation, the arrangement of the light emitting elements 12 on the bearing surface 101 may be defined by an arrangement of arranging or disposing a plurality of the mounting bases 13.

Wherein the protector 20 serves as a protection and an external decoration member. In a specific implementation, the protection member 20 is a hollow member extending along the first direction X.

More specifically, the first mounting side plate 222, the second mounting side plate 223, the mounting plate 221 and the first lens layer 211 jointly enclose the receiving cavity 201, and the light source assembly 10 is mounted on one side of the mounting plate 221 facing the first lens layer 211; the first mounting side plate 222, the second mounting side plate 223, the first lens layer 211, and the second lens layer 212 collectively enclose the gap 202.

In practical implementation, the outer surface of the mounting portion 22 is configured as a fixing surface 203, and in practical implementation, the linear lighting module is fixedly mounted on a mounting base through the fixing surface 203. In an embodiment, in order to improve the mounting stability of the mounting portion 22, a protrusion extending along the first direction X may be further provided on the fixing surface 203, and a groove corresponding to the protrusion may be formed on the mounting base. At this time, the protrusion plays a role of sliding guide in the installation process of the linear lighting module 100 to ensure the accurate installation position of the linear lighting module 100, and can also be used for fixing and positioning the linear lighting module 100, and the linear lighting module 100 is prevented from being separated from the installation base 10.

In this embodiment, the fixing surface 203 is an outer surface of the mounting plate 221, the first mounting side plate 222 and the second mounting side plate 223 facing away from the hollow space. Preferably, the first and second

The first lens layer 211 has a first entrance surface 2111 and a first exit surface 2112 which face away from each other in the thickness direction thereof. The first incidence surface 2111 is disposed facing the receiving cavity 201, and the first incidence surface 2111 is a free-form surface.

Similarly, the thickness direction of the second lens layer 212 is consistent with the light exiting direction (i.e. the second direction Y) of the linear illumination module 100, and the second lens layer 212 has a second incident surface 2121 and a second exiting surface 2122 facing away from each other in the thickness direction.
