[0031] As shown in Figures 1 to 7 The light-emitting assembly 100 includes a housing, a first type of light-emitting piece and a second type of light-emitting piece, the first type of light-emitting piece and the second type of light-emitting piece are arranged inside the housing, the housing is arranged on the top of the vehicle body 300, the illumination range of the first type of light-emitting piece is different from the illumination range of the second type of light-emitting piece, and / or the illuminance of the first type of light-emitting piece is different from the illuminance of the second type of light-emitting piece.

[0032] In the embodiment of the application, the light-emitting assembly 100 can be applied in a vehicle, specifically, the light-emitting assembly 100 can be applied in the vehicle body 300 of the vehicle, and the light-emitting assembly 100 is arranged on the top of the vehicle body 300, the vehicle body 300 is provided with a seat assembly 200, and the light-emitting assembly 100 faces the seat assembly 200, so that once the light-emitting assembly 100 emits light, the light of the light-emitting assembly 100 can be irradiated on the seat assembly, so that when a user rides the vehicle, the light of the light-emitting assembly 100 can provide illumination for the user on the seat assembly.

[0033] In the embodiment of the application, since the first type of light-emitting piece and the second type of light-emitting piece are arranged inside the housing, the housing is arranged on the top of the vehicle body 300, the illumination range of the first type of light-emitting piece is different from the illumination range of the second type of light-emitting piece, and / or the illuminance of the first type of light-emitting piece is different from the illuminance of the second type of light-emitting piece, therefore, when the first type of light-emitting piece and the second type of light-emitting piece emit light, the range of the light of the first type of light-emitting piece transmitted to the seat assembly 200 is different from the range of the light of the second type of light-emitting piece transmitted to the seat assembly 200, and / or the illuminance of the first type of light-emitting piece is different from the illuminance of the second type of light-emitting piece, so that the level of the light on the seat assembly 200 is improved. That is, in the embodiment of the application, by arranging the first type of light-emitting piece and the second type of light-emitting piece, when the first type of light-emitting piece and the second type of light-emitting piece emit light, the level of the light on the seat assembly 200 is improved, so that the experience of the user in the vehicle is improved.

[0034] It should be noted that in the embodiments of the present application, the first type of light emitting member can be made to emit light, the second type of light emitting member can be made to emit light, of course, the first type of light emitting member can also be made not to emit light, the second type of light emitting member can be made to emit light, and the first type of light emitting member can be made to emit light, and the second type of light emitting member can be made not to emit light. When the first type of light emitting member and the second type of light emitting member both emit light, the light emitted by the light emitting assembly 100 has a larger brightness, making the interior of the vehicle brighter.

[0035] In addition, in the embodiments of the present application, the illumination range of the first type of light emitting member can be made different from the illumination range of the second type of light emitting member, the illuminance of the first type of light emitting member can be made different from the illuminance of the second type of light emitting member, or the illumination range of the first type of light emitting member can be made different from the illumination range of the second type of light emitting member, and the illuminance of the first type of light emitting member can be made different from the illuminance of the second type of light emitting member. The embodiments of the present application do not limit this.

[0036] In addition, in some embodiments, the illumination range of the first type of light emitting member is greater than the illumination range of the second type of light emitting member. By such a setting, when the light emitting assembly 100 is applied to the vehicle body 300, once the first type of light emitting member and the second type of light emitting member emit light at the same time, the seat assembly 200 in the vehicle body 300 can be irradiated by light emitting members with different illumination ranges, thereby helping to improve the light level on the seat assembly 200.

[0037] In addition, in some embodiments, the illumination range of the second type of light emitting member at least partially overlaps the illumination range of the first type of light emitting member. By such a setting, when the light emitting assembly 100 is applied to the vehicle body 300, the illumination range of the second type of light emitting member can be located in the illumination range of the first type of light emitting member, once the first type of light emitting member and the second type of light emitting member emit light at the same time, the light level is higher at the position where the illumination ranges of the first type of light emitting member and the second type of light emitting member overlap, thereby improving the light level on the seat assembly 200.

[0038] In addition, in some embodiments, the illuminance of the first type of light emitting member is less than the illuminance of the second type of light emitting member. By such a setting, when the first type of light emitting member and the second type of light emitting member emit light at the same time, the light level on the seat assembly 200 can be improved.

[0039] In addition, in some embodiments, the illuminance of the first type of light emitting member is greater than the illuminance of the second type of light emitting member. By such a setting, when the first type of light emitting member and the second type of light emitting member emit light at the same time, the light level on the seat assembly 200 can be improved.

[0040] In addition, in some embodiments, the light-emitting assembly 100 further comprises a first condenser; the first condenser is arranged in the housing, and the first light-emitting element is directed towards the first condenser, and the light of the first light-emitting element can pass through the first condenser. By arranging the first condenser, once the first light-emitting element emits light, the light of the first light-emitting element can pass through the first condenser, and the first condenser can condense the light of the first light-emitting element, so that the more condensed light irradiates on the seat assembly 200 of the vehicle, avoiding the problem that the more dispersed light irradiates on the seat assembly 200 of the vehicle, causing the passengers to be dazzled.

[0041] In addition, in some embodiments, the light-emitting assembly 100 further comprises a second condenser; the second condenser is arranged in the housing, and the second light-emitting element is directed towards the second condenser, and the light of the second light-emitting element can pass through the second condenser. By arranging the second condenser, once the second light-emitting element emits light, the light of the second light-emitting element can pass through the second condenser, and the second condenser can condense the light of the second light-emitting element, so that the more condensed light irradiates on the seat assembly 200 of the vehicle, avoiding the problem that the more dispersed light irradiates on the seat assembly 200 of the vehicle, causing the passengers to be dazzled.

[0042] In addition, in some embodiments, the number of the first light-emitting elements and the number of the second light-emitting elements are both plural, one first light-emitting element and one second light-emitting element form a light-emitting element group, and the plurality of light-emitting element groups are distributed in the housing.

[0043] When the plurality of light-emitting element groups are distributed in the housing, at this time, once the plurality of light-emitting element groups emit light at the same time, the irradiation range and / or the illuminance of the first light-emitting element and the second light-emitting element in each light-emitting element group are different, so that the light emitted by each light-emitting element group has higher level, and thus the light irradiating on the seat assembly 200 has higher level. That is, by arranging the plurality of light-emitting element groups, the level of the light irradiating on the seat assembly 200 can be further improved.

[0044] It should be noted that the number of the light-emitting element groups can be set according to actual needs, for example, the number of the light-emitting element groups is 2, and for another example, the number of the light-emitting element groups is 3. In this regard, the embodiments of the present application are not limited here.

[0045] In addition, in some embodiments, the uniformity of the light of the first light-emitting element is less than or equal to 3, and the uniformity of the light of the first light-emitting element is that, on a circle formed in the irradiation range of the first light-emitting element, the ratio of the illuminance of the light at the center of the circle to the maximum and minimum of the illuminance of the light at a plurality of positions on the edge of the circle.

[0046] When the uniformity of the light rays emitted by the first light emitting component is less than or equal to 3, when the light emitting assembly 100 is applied in a vehicle, the light rays emitted by the first light emitting component can better illuminate the seat assembly 200 of the vehicle, and the level of the light rays illuminated on the seat assembly 200 of the vehicle is improved.

[0047] In addition, in some embodiments, the seat assembly 200 can include a front seat assembly 210, the light emitting assembly 100 includes a front light emitting assembly 10, the front light emitting assembly 10 includes a front shell 11, a front first light emitting component 12 and a front second light emitting component 13, and the front first light emitting component 12 and the front second light emitting component 13 are both arranged inside the front shell 11; the illumination range of the front first light emitting component 12 is greater than the illumination range of the front second light emitting component 13, and the front first light emitting component 12 and the front second light emitting component 13 are oriented in the same direction, the illumination range of the front second light emitting component 13 is located inside the illumination range of the front first light emitting component 12, and the front first light emitting component 12 and the front second light emitting component 13 are both oriented towards the front seat assembly 210.

[0048] Through such an arrangement, when a user sits on the front seat assembly 210, the illumination range of the front second light emitting component 13 is located within the illumination range of the front first light emitting component 12, so that the user on the front seat can see two types of light rays, thereby improving the level of the light rays of the front light emitting assembly 10, and the light rays of the front second light emitting component 13 are more concentrated, so that the user on the front seat assembly 210 can better read, read books, etc. through the front light emitting assembly 10, thereby improving the user experience.

[0049] It should be noted that the front second light emitting component 13 can be a spotlight, and the front first light emitting component 12 can be a floodlight. Of course, the front second light emitting component 13 can also be of other types, and the front first light emitting component 12 can also be of other types.

[0050] In addition, in some embodiments, the front shell 11 is provided with a front first condenser and a front second condenser; the front first light emitting component 12 is oriented towards the front first condenser, the front second light emitting component 13 is oriented towards the front second condenser, the light rays of the front first light emitting component 12 pass through the front first condenser to illuminate the front seat assembly 210, and the light rays of the front second light emitting component 13 pass through the front second condenser to illuminate the front seat assembly 210.

[0051] With such an arrangement, once the front row first type light emitting member 12 emits light, the light of the front row first type light emitting member 12 can pass through the first light collector, so that the first light collector can collect the light of the front row first type light emitting member 12, avoiding the problem that the light of the front row first type light emitting member 12 is relatively dispersed, resulting in the problem that the user on the front row seat feels that the light is relatively dazzling. Similarly, once the front row second type light emitting member 13 emits light, the light of the front row second type light emitting member 13 can pass through the second light collector, so that the second light collector can collect the light of the front row second type light emitting member 13, avoiding the problem that the light of the front row second type light emitting member 13 is relatively dispersed, resulting in the problem that the user on the front row seat feels that the light is relatively dazzling.

[0052] In addition, in some embodiments, the front row first type light emitting member 12 forms a front row first irradiation range at the front row seat assembly 210, which is larger than a front row second irradiation range formed by the front row second type light emitting member 13 at the front row seat, and the front row second irradiation range is located inside the front row first irradiation range, and the illuminance of the light of the front row first type light emitting member 12 in the front row first irradiation range is less than the illuminance of the light of the front row second type light emitting member 13 in the front row second irradiation range.

[0053] With such an arrangement, when the front row first type light emitting member 12 and the front row second type light emitting member 13 both emit light, the front row second type light emitting member 13 is brighter than the front row first type light emitting member 12, so that the user on the front row seat assembly 210 feels that the light has a stronger sense of hierarchy, and the front row second type light emitting member 13 can ensure that the user on the front row seat assembly 210 has sufficient illuminance of light available, facilitating the user to read, learn, etc. on the front row seat assembly 210.

[0054] In addition, in some embodiments, the front row first irradiation range is in the shape of a circle with a diameter of 600 millimeters, the front row second irradiation range is in the shape of a circle with a diameter of 300 millimeters, and the illuminance of the light of the front row first type light emitting member 12 in the front row first irradiation range ranges from 10 to 40 lux, and the illuminance of the light of the front row second type light emitting member 13 in the front row second irradiation range ranges from 40 to 80 lux; wherein the uniformity of the light of the front row first type light emitting member 12 in the front row first irradiation range is less than or equal to 2, and the uniformity of the light of the front row first type light emitting member 12 in the front row first irradiation range is that, on the circle formed by the front row first irradiation range, the ratio of the illuminance of the light at the center of the circle to the maximum and minimum of the illuminance of the light at multiple positions on the edge of the circle.

[0055] The illuminance of the light rays of the first front row type light emitting member 12 in the first front row illumination range is set to be 10-40 lux, and the illuminance of the light rays of the second front row type light emitting member 13 in the second front row illumination range is set to be 40-80 lux, which is equivalent to that the illuminance of the second front row type light emitting member 13 is twice that of the first front row type light emitting member 12 on the front row seat assembly 210, so that the light rays on the front row seat assembly 210 have a stronger sense of hierarchy, and the light rays have sufficient illuminance, which is convenient for the user to study, read, etc. on the front row seat assembly 210. In addition, the uniformity of the light rays of the first front row type light emitting member 12 in the first front row illumination range is less than or equal to 2, which can ensure that the light rays on the front row seat assembly 210 are relatively uniform, avoiding the problem of uneven distribution of light rays affecting the user experience.

[0056] It should be noted that once the first front row type light emitting member 12 emits light, the light rays of the first front row type light emitting member 12 irradiate on the front row seat assembly 210, and the irradiation range of the light rays can form a circle according to a preset diameter, for example, as shown in Figure 5 The first front row illumination range forms a circle, at this time, the center position of the circle is position A, and the edge of the circle has positions B, C, D, and E, so that the uniformity of the light rays of the first front row type light emitting member 12 in the first front row illumination range can be: each position has an illuminance value of the light rays, which is equivalent to having multiple illuminance values, and the ratio between the maximum illuminance value and the minimum illuminance value in the multiple illuminance values. Wherein, if the illuminance at position A is the maximum illuminance, and the illuminance at position C is the minimum illuminance, the uniformity can be the ratio of the illuminance value at position A to the illuminance value at position C.

[0057] In addition, in the embodiment of the present application, the uniformity of the light rays of the first front row type light emitting member 12 in the first front row illumination range can be any value less than or equal to 2, for example, the uniformity of the light rays of the first front row type light emitting member 12 in the first front row illumination range can be 2, and for another example, the uniformity of the light rays of the first front row type light emitting member 12 in the first front row illumination range can be 1. For this, the embodiment of the present application is not limited here.

[0058] In addition, in some embodiments, the vehicle seat further comprises a second-row seat assembly 220 adjacent to the front-row seat assembly 210 in the driving direction of the vehicle, and the light-emitting assembly 100 comprises a second-row light-emitting assembly 20, the second-row light-emitting assembly 20 comprising a second-row housing 21, second-row first-type light-emitting pieces 22, and second-row second-type light-emitting pieces 23, the second-row first-type light-emitting pieces 22 and the second-row second-type light-emitting pieces 23 being arranged inside the second-row housing 21; the irradiation range of the second-row first-type light-emitting pieces 22 is larger than that of the second-row second-type light-emitting pieces 23, the second-row first-type light-emitting pieces 22 and the second-row second-type light-emitting pieces 23 are oriented differently, the irradiation range of the second-row first-type light-emitting pieces 22 partially overlaps that of the second-row second-type light-emitting pieces 23, and the second-row first-type light-emitting pieces 22 and the second-row second-type light-emitting pieces 23 are both oriented towards the second-row seat assembly 220.

[0059] Generally, the second-row seat assembly 220 is provided with a table board and the like auxiliary member, and the user can place books and the like on the table board. In the embodiments of the present application, by arranging the second-row first-type light-emitting pieces 22 and the second-row second-type light-emitting pieces 23 to be oriented differently and the irradiation range of the second-row first-type light-emitting pieces 22 to partially overlap that of the second-row second-type light-emitting pieces 23, when the user sits on the second-row seat assembly 220, the user can be equivalent to see two kinds of light, thereby improving the gradation of the light of the second-row light-emitting assembly 20, and the light of the second-row second-type light-emitting pieces 23 is relatively concentrated, the relatively concentrated light can be irradiated on the table board, the light of the second-row first-type light-emitting pieces 22 is relatively dispersed, and the relatively dispersed light is irradiated on other positions, so that the brightness of the light at the second-row seat assembly 220 is relatively high, and the light on the table board is relatively concentrated, which is conducive to reading, book-reading and the like through the table board on the second-row seat assembly 220, and improves the experience of the user.

[0060] It should be noted that the second-row second-type light-emitting pieces 23 can be spotlights, and the second-row first-type light-emitting pieces 22 can be floodlights. Of course, the second-row second-type light-emitting pieces 23 can also be other types, and the second-row first-type light-emitting pieces 22 can also be other types.

[0061] In addition, in some embodiments, the second-row housing 21 is provided with a second-row first light condenser and a second-row second light condenser; the second-row first-type light-emitting pieces 22 are oriented towards the second-row first light condenser, and the second-row second-type light-emitting pieces 23 are oriented towards the second-row second light condenser; the light of the second-row first-type light-emitting pieces 22 passes through the second-row first light condenser to be irradiated on the second-row seat assembly 220, and the light of the second-row second-type light-emitting pieces 23 passes through the second-row second light condenser to be irradiated on the second-row seat assembly 220.

[0062] Through the arrangement, once the second-row first light emitting elements 22 emit light, the light of the second-row first light emitting elements 22 can pass through the first light collector, so that the first light collector can collect the light of the second-row first light emitting elements 22, avoiding the problem that the light of the second-row first light emitting elements 22 is relatively dispersed, resulting in the problem that the user on the second-row seat feels that the light is relatively dazzling. Similarly, once the second-row second light emitting elements 23 emit light, the light of the second-row second light emitting elements 23 can pass through the second light collector, so that the second light collector can collect the light of the second-row second light emitting elements 23, avoiding the problem that the light of the second-row second light emitting elements 23 is relatively dispersed, resulting in the problem that the user on the second-row seat feels that the light is relatively dazzling.

[0063] In addition, in some embodiments, the second-row first irradiation range formed by the second-row first light emitting elements 22 at the second-row seat assembly 220 is larger than the second-row second irradiation range formed by the second-row second light emitting elements 23 at the second-row seat, and the second-row second irradiation range partially overlaps the second-row first irradiation range, and the illuminance of the light of the second-row first light emitting elements 22 in the second-row first irradiation range is less than the illuminance of the light of the second-row second light emitting elements 23 in the second-row second irradiation range.

[0064] Through the arrangement, when the second-row first light emitting elements 22 and the second-row second light emitting elements 23 both emit light, the second-row second light emitting elements 23 are brighter than the second-row first light emitting elements 22, so that the user on the second-row seat assembly 220 feels that the light has stronger gradation, and the second-row second light emitting elements 23 can ensure that the user on the second-row seat assembly 220 has sufficient light with sufficient illuminance, which is convenient for the user to read, learn, etc. on the second-row seat assembly 220.

[0065] In addition, in some embodiments, the shape of the second-row first irradiation range is a circle with a diameter of 600 millimeters, the shape of the second-row second irradiation range is a circle with a diameter of 400 millimeters, and the range of the illuminance of the light of the second-row first light emitting elements 22 in the second-row first irradiation range is 10-40 lux, and the range of the illuminance of the light of the second-row second light emitting elements 23 in the second-row second irradiation range is 80-200 lux; wherein the uniformity of the light of the second-row first light emitting elements 22 in the second-row first irradiation range is less than or equal to 3, and the uniformity of the light of the second-row second light emitting elements 23 in the second-row second irradiation range is less than or equal to 2.

[0066] The range of the illuminance of the light rays of the second-row first type light emitting member 22 in the second-row first irradiation range is 10-40 lux, and the range of the illuminance of the light rays of the second-row second type light emitting member 23 in the second-row second irradiation range is 80-200 lux, which is equivalent to that the illuminance of the second-row second type light emitting member 23 on the second-row seat assembly 220 is at least 2 times the illuminance of the second-row first type light emitting member 22, so that the light rays on the second-row seat assembly 220 have a stronger sense of hierarchy, and the light rays have sufficient illuminance, which is convenient for the user to learn, read, etc. on the second-row seat assembly 220. In addition, the uniformity of the light rays of the second-row first type light emitting member 22 in the second-row first irradiation range is less than or equal to 3, and the uniformity of the light rays of the second-row second type light emitting member 23 in the second-row second irradiation range is less than or equal to 2, which can ensure that the light rays on the second-row seat assembly 220 and the table plate are relatively uniform, and avoid the problem of uneven distribution of light rays affecting the user experience.

[0067] It should be noted that the uniformity of the light rays of the second-row first type light emitting member 22 in the second-row first irradiation range can refer to the uniformity of the light rays of the first-row first type light emitting member 12 in the first-row first irradiation range, which will not be repeated here. The uniformity of the light rays of the second-row second type light emitting member 23 in the second-row second irradiation range can refer to the uniformity of the light rays of the first-row first type light emitting member 12 in the first-row first irradiation range, which will not be repeated here.

[0068] In addition, in the embodiment of the present application, the ratio of the brightness of the second-row second type light emitting member 23 to the brightness of the second-row first type light emitting member 22 is N, which satisfies: 4.5≤N≤5. Through such a setting, when the second-row second type light emitting member 23 and the second-row first type light emitting member 22 are both emitting light, the light rays at the second-row seat assembly 220 have a higher sense of hierarchy.

[0069] It should be noted that N can be any value between 4.5 and 5. For example, N is 4.5, for another example, N is 4.6, for another example, N is 4.8, and for another example, N is 5.

[0070] In addition, in some embodiments, the vehicle seat further comprises a third-row seat assembly 230, the third-row seat assembly 230 is adjacent to the second-row seat assembly 220 in the driving direction of the vehicle, and the second-row seat assembly 220 is located between the front-row seat assembly 210 and the third-row seat assembly 230. The light-emitting assembly 100 comprises a third-row light-emitting assembly 30, the third-row light-emitting assembly 30 comprises a third-row shell 31, third-row first-type light-emitting pieces 32, and third-row second-type light-emitting pieces 33, and the third-row first-type light-emitting pieces 32 and the third-row second-type light-emitting pieces 33 are arranged inside the third-row shell 31; the irradiation range of the third-row first-type light-emitting pieces 32 is larger than the irradiation range of the third-row second-type light-emitting pieces 33, and the third-row first-type light-emitting pieces 32 and the third-row second-type light-emitting pieces 33 are oriented in the same direction, the irradiation range of the third-row first-type light-emitting pieces 32 is inside the irradiation range of the third-row second-type light-emitting pieces 33, and the third-row first-type light-emitting pieces 32 and the third-row second-type light-emitting pieces 33 are both oriented towards the third-row seat assembly 230.

[0071] Through such an arrangement, when a user sits on the third-row seat assembly 230, the irradiation range of the third-row second-type light-emitting pieces 33 is inside the irradiation range of the third-row first-type light-emitting pieces 32, so that the user on the third-row seat can see two types of light, thereby improving the gradation of the light of the third-row light-emitting assembly 30, and the light of the third-row second-type light-emitting pieces 33 is more concentrated, so that the user on the third-row seat assembly 230 can better read, read books, etc. through the third-row light-emitting assembly 30, thereby improving the user experience.

[0072] It should be noted that the third-row second-type light-emitting pieces 33 can be spotlights, and the third-row first-type light-emitting pieces 32 can be floodlights. Of course, the third-row second-type light-emitting pieces 33 can also be other types, and the third-row first-type light-emitting pieces 32 can also be other types.

[0073] In addition, in some embodiments, the third-row shell 31 is provided with a third-row first condenser and a third-row second condenser; the third-row first-type light-emitting pieces 32 are oriented towards the third-row first condenser, the third-row second-type light-emitting pieces 33 are oriented towards the third-row second condenser, the light of the third-row first-type light-emitting pieces 32 passes through the third-row first condenser to irradiate on the third-row seat assembly 230, and the light of the third-row second-type light-emitting pieces 33 passes through the third-row second condenser to irradiate on the third-row seat assembly 230.

[0074] Through the arrangement, once the three rows of first light emitting pieces 32 emit light, the light of the three rows of first light emitting pieces 32 can pass through the first light collector, so that the first light collector can collect the light of the three rows of first light emitting pieces 32, avoiding the problem that the light of the three rows of first light emitting pieces 32 is relatively dispersed, resulting in the problem that the user on the three-row seat feels that the light is relatively dazzling. Similarly, once the three rows of second light emitting pieces 33 emit light, the light of the three rows of second light emitting pieces 33 can pass through the second light collector, so that the second light collector can collect the light of the three rows of second light emitting pieces 33, avoiding the problem that the light of the three rows of second light emitting pieces 33 is relatively dispersed, resulting in the problem that the user on the three-row seat feels that the light is relatively dazzling.

[0075] In addition, in some embodiments, the three-row first illumination range formed by the three rows of first light emitting pieces 32 at the three-row seat assembly 230 is greater than the three-row second illumination range formed by the three rows of second light emitting pieces 33 at the three-row seat, and the three-row second illumination range partially overlaps the three-row first illumination range. The illuminance of the light of the three rows of first light emitting pieces 32 in the three-row first illumination range is less than the illuminance of the light of the three rows of second light emitting pieces 33 in the three-row second illumination range.

[0076] Through the arrangement, when the three rows of first light emitting pieces 32 and the three rows of second light emitting pieces 33 both emit light, the three rows of second light emitting pieces 33 are brighter than the three rows of first light emitting pieces, so that the user on the three-row seat assembly 230 feels that the light has a stronger sense of hierarchy, and the three rows of second light emitting pieces 33 can ensure that the user on the three-row seat assembly 230 has sufficient illuminance of light available, facilitating the user to read, learn, etc. on the three-row seat assembly 230.

[0077] In addition, in some embodiments, the three-row first illumination range is a circular shape with a diameter of 600 millimeters, the three-row second illumination range is a circular shape with a diameter of 300 millimeters, and the illuminance of the light of the three rows of first light emitting pieces 32 in the three-row first illumination range ranges from 10 to 40 lux, and the illuminance of the light of the three rows of second light emitting pieces 33 in the three-row second illumination range ranges from 30 to 80 lux. The uniformity of the light of the three rows of first light emitting pieces 32 in the three-row first illumination range is less than or equal to 3, and the uniformity of the light of the three rows of second light emitting pieces 33 in the three-row second illumination range is less than or equal to 2.

[0078] By setting the range of the illuminance of the light rays of the three rows of first type light emitting pieces 32 in the three rows of first illumination ranges to be 10-40 lux, and the range of the illuminance of the light rays of the three rows of second type light emitting pieces 33 in the three rows of second illumination ranges to be 40-80 lux, it is equivalent to that on the three-row seat assembly 230, the illuminance of the three rows of second type light emitting pieces 33 is 2 times the illuminance of the three rows of first type light emitting pieces 32, so that the light rays on the three-row seat assembly 230 have stronger layering, and the light rays can have sufficient illuminance, so as to facilitate the user to learn, read and the like on the three-row seat assembly 230. In addition, the uniformity of the light rays of the three rows of first type light emitting pieces 32 in the three rows of first illumination ranges is less than or equal to 3, and the uniformity of the light rays of the three rows of second type light emitting pieces 33 in the three rows of second illumination ranges is less than or equal to 2, so as to ensure that the light rays on the three-row seat assembly 230 are relatively uniform, and avoid the problem of uneven distribution of light rays affecting the user experience.
