Description

Technical Field

[0001] The utility model relates to the technical field of atmosphere lamp devices, and particularly relates to an end cap structure of a double-layer lampshade atmosphere lamp. Background Art

[0002] In conventional table lamps, desk lamps or atmosphere lamps, usually a layer of lampshade or a light-transmitting layer is arranged outside the main light source. On the one hand, it is used to protect the internal main light source and prevent dust from adhering to the main light source, resulting in a reduction in the service life of the light source. On the other hand, the curved surface of the lampshade can effectively enhance the scattering of light and improve the brightness and uniformity of the lamp. However, usually, the light-transmitting property of a single-layer lampshade is relatively strong. When the user increases the luminous brightness of the light source, the light emitted by the lamp through the single-layer lampshade is still relatively dazzling. Therefore, in the prior art, some lamps are provided with two layers of lampshades outside the main light source to change the emission angle of light, improve the scattering effect, so that the light emitted by the lamp can achieve high brightness and is not too dazzling, but is softer and more uniform.

[0003] However, setting two layers of lampshades increases the complexity of lamp assembly. For most lamps, the lampshades are fixed by glue. But when there is a need to disassemble the lamp, it is difficult to disassemble and reassemble. For example, the patent with the publication number CN215808205U provides an atmosphere lamp. The lamp is provided with inner and outer two layers of lampshades. Among them, the bottom of the inner lampshade is provided with a plurality of screw fixing positions, and the bottom of the outer lampshade is provided with a plurality of positioning grooves. The inner lampshade and the lamp base are fixedly connected by screws, and the bottom of the outer lampshade is fitted and connected with a plurality of convex blocks arranged on the base. Although the lampshades of this atmosphere lamp can be assembled and disassembled, the loading and unloading of the inner lampshade are more troublesome. And although the outer lampshade is convenient for loading and unloading, the connection between the outer lampshade and the base is unstable and is easily separated due to some small bumps.

[0004] Therefore, there is an urgent need to provide an end cap structure of a double-layer lampshade atmosphere lamp to solve the above technical problems. Summary of the Invention

[0005] In view of the problems in the related art, the utility model proposes an end cap structure of a double-layer lampshade atmosphere lamp, which is convenient for assembly and disassembly and can ensure stable fixation during connection.

[0006] The utility model is realized as follows:

[0007] An end cap structure of a double-layer lampshade atmosphere lamp, comprising an upper cover and a base. An inner lampshade and an outer lampshade are fixedly arranged between the upper cover and the base; on two opposite end faces of the upper cover and the base, there are both annularly arranged first limiting grooves, and on the circumferential side of the first limiting grooves, there are also annularly arranged second limiting grooves; both the inner lampshade and the outer lampshade are tubular structures with a hollow interior and openings at both ends. The openings at both ends of the inner lampshade respectively cooperate with the first limiting grooves; the openings at both ends of the outer lampshade respectively cooperate with the second limiting grooves;

[0008] A connecting piece is arranged in the inner cavity of the inner lampshade, and both ends of the connecting piece are fixedly connected to the upper cover and the base respectively;

[0009] It further includes a first light-emitting unit, and the first light-emitting unit is fixedly arranged on the circumferential side of the connecting piece.

[0010] Through the connecting piece, the upper cover and the base can be relatively connected to a fixed position, and the three can be fixedly connected by at least two screws. The inner lampshade is clamped between the two first limiting grooves of the upper cover and the base, and the outer lampshade is clamped between the two second limiting grooves of the upper cover and the base, which is convenient for the disassembly and assembly of the lamp and can also ensure the stability of the connection.

[0011] As a further optimization of the above solution, the connecting piece is a tubular structure with a hollow interior and openings at both ends; in the middle area of the first limiting groove, there is an annularly arranged third limiting groove;

[0012] The inner diameter dimension of the opening of the connecting piece and the inner diameter dimension of the third limiting groove cooperate with each other; both openings at both ends of the connecting piece are embedded at the third limiting groove.

[0013] The cross-section of the above-mentioned tubular structure is of any shape profile, including circular and square, corresponding to a cylindrical tubular structure and a cuboid tubular structure, etc. Correspondingly, the "diameter" in the "inner diameter dimension" refers to the radial dimension. Setting the third limiting groove can limit the relative positions of the connecting piece, the upper cover and the base, and effectively improve the stability of the connection of the three.

[0014] As a further optimization of the above solution, the first light-emitting unit is an LED lamp board fixedly attached to the circumferential side of the connecting piece. A plurality of lamp beads are arranged on the outer side wall of the LED lamp board; the LED lamp board is formed into a tubular structure adapted to the outer side wall of the connecting piece, and both ends extend into the third limiting groove.

[0015] The first light-emitting unit is of a tubular structure, which is convenient for installation. At the same time, the third limiting groove can further improve the installation stability of the first light-emitting unit.

[0016] As a further optimization of the above solution, the upper cover includes an outer housing; the connecting member and the outer housing are made of one of aluminum, copper, aluminum alloy or copper alloy.

[0017] Aluminum, copper, aluminum alloy and copper alloy are all metal materials with strong thermal conductivity and high cost performance; a large number of lamp beads are provided on the cylindrical first light-emitting unit, which will generate high heat; while the connecting member is used as a fixing member, it also plays a role in heat conduction, and conducts the heat generated by the lamp beads along the back of the first light-emitting unit, the connecting member, and the outer housing, and then exchanges heat with the air.

[0018] As a further optimization of the above solution, the atmosphere lamp includes a built-in power supply, and the built-in power supply is fixedly arranged in the inner cavity of the connecting member; on the upper side end surface of the base, a fourth limiting groove is provided in the middle area of the third limiting groove, and the fourth limiting groove cooperates with the bottom of the built-in power supply.

[0019] The built-in power supply is used to supply power to the circuit structure inside the atmosphere lamp including the first light-emitting unit; installing the built-in power supply in the inner cavity of the connecting member can improve the overall space utilization rate of the atmosphere lamp.

[0020] As a further optimization of the above solution, a limiting rib in the shape of an annular protrusion is provided along the opening edge of the outer lamp cover; the limiting rib cooperates with the second limiting groove.

[0021] As a further optimization of the above solution, the limiting rib has a convex-shaped contour in the longitudinal section of the outer lamp cover; the second limiting groove has a concave-shaped contour in the longitudinal section of the upper cover; when the limiting rib and the second limiting groove are connected in cooperation, a smooth transition connection is formed between the outer side walls of the upper cover, the base and the outer lamp cover.

[0022] The setting of the concave-shaped contour of the second limiting groove and the convex-shaped contour of the limiting rib makes the side of the atmosphere lamp still a smooth curve when the upper cover and the outer lamp cover, and the base and the outer lamp cover are connected, avoiding uneven features and maintaining the aesthetic appearance.

[0023] As a further optimization of the above solution, it further includes a second light-emitting unit; the light rays emitted by the first light-emitting unit and the second light-emitting unit have different colors; the second light-emitting unit is arranged along the bottom of the first limiting groove of the base;

[0024] A ring-shaped light-transmitting member adapted to the first limiting groove is fixedly provided directly above the second light-emitting unit; the bottom of the inner lamp cover abuts against the light-transmitting member.

[0025] The first light-emitting unit serves as the main light source and usually emits white light; the second light-emitting unit serves as the auxiliary light source and usually emits blue light as a cool color tone, or emits yellow light as a warm color tone, etc. The second light-emitting unit cooperates with the first light-emitting unit to adjust the color tone of the light finally emitted by the atmosphere lamp.

[0026] As a further optimization of the above solution, the inner lamp shade is a light guide plate.

[0027] The light emitted by the second light-emitting unit is scattered along the light guide plate, and the light emitted by the first light-emitting unit is incident from the side of the light guide plate. After the two kinds of light are mixed, they are emitted from the outer lamp shade.

[0028] As a further optimization of the above solution, the inner lamp shade includes a first inner cover and a second inner cover. The first inner cover is sleeved in the inner cavity of the second inner cover; a gap is formed between the first inner cover and the second inner cover.

[0029] Although the light guide plate has high light guiding performance, it still causes light attenuation, resulting in uneven distribution of the second light-emitting unit on the upper and lower sides of the inner lamp shade. By providing the mutually nested first inner cover and second inner cover, the light emitted by the second light-emitting unit passes through the light-transmitting member, uniformly gathers in the gap area, and then is scattered and emitted from the sides of the first and second inner covers, and is more uniformly mixed with the light emitted by the first light-emitting unit.

[0030] The beneficial effects are as follows:

[0031] The present utility model provides an end cap structure of a double-layer lamp shade atmosphere lamp. The atmosphere lamp includes an upper cover and a base. First limiting grooves and second limiting grooves corresponding to each other are provided on the two end faces of the upper cover and the base that are opposite to each other, respectively, for limiting the positions of the inner lamp shade and the outer lamp shade, and the upper cover and the base are fixedly connected by providing a connecting member. During assembly, only the connecting member needs to be fixed to the upper cover and the base, and the inner lamp shade and the outer lamp shade are clamped between the base and the upper cover, which is quick and convenient to load and unload, and has high connection stability.

[0058] Such as Figures 1 to 7As shown in the figure, this embodiment provides an end - cap structure for a double - layer lamp - shade atmosphere lamp, which includes an upper cover 1 and a base 2. An inner lamp - shade 3 and an outer lamp - shade 4 are fixedly arranged between the upper cover 1 and the base 2;

[0060] In the middle area of the first limiting groove 5, there is a third limiting groove 7 arranged in a ring shape;

[0061] In the middle area of the third limiting groove 7 on the upper - side end face of the base 2, there is a fourth limiting groove 8;

[0062] That is, the fourth limiting groove 8, the third limiting groove 7, the first limiting groove 5, and the second limiting groove 6 are nested in sequence from the inside out.

[0063] A connecting piece 9 is arranged in the inner cavity of the inner lamp - shade 3, which is made of aluminum alloy. The two ends of the connecting piece 9 are respectively fixedly connected to the upper cover 1 and the base 2. In this embodiment, the connecting piece 9 is a hollow cylindrical structure with both ends open. All the cylindrical structures mentioned in this embodiment are cylindrical, and their cross - sections are all circular. The inner - diameter size of the opening of the connecting piece 9 and the inner - diameter size of the third limiting groove 7 are mutually matched. Both ends of the opening of the connecting piece 9 are embedded in the third limiting groove 7.

[0064] Setting the third limiting groove 7 can limit the relative positions of the connecting piece 9, the upper cover 1, and the base 2, effectively improving the stability of the connection among the three.

[0065] While the connecting piece 9 serves as a fixing piece, its aluminum alloy also plays a role in heat conduction, and cooperating with the upper cover 1 can effectively improve the heat - dissipation performance of the atmosphere lamp.

[0066] In this embodiment, several screw - fixing positions are arranged on the inner - side wall of the connecting piece 9. On the end face of the upper cover 1 facing downward and the end face of the base 2 facing upward, there are several screw holes. The connecting piece 9 is fixedly connected to the upper cover 1 and the base 2 through screws.

[0067] The atmosphere lamp further includes a first light - emitting unit 10, a second light - emitting unit 11, and a built - in power supply 12;

[0068] In this embodiment, the first light - emitting unit 10 is an LED lamp board fixedly attached to the peripheral side of the connecting piece 9. Several lamp beads are arranged on the outer - side wall of the LED lamp board. The LED lamp board is formed into a cylindrical structure adapted to the outer - side wall of the connecting piece 9, and both ends extend into the third limiting groove 7.

[0069] The first light-emitting unit 10 is a cylindrical structure, which is convenient for installation. At the same time, the third limiting groove 7 can further improve the installation stability of the first light-emitting unit 10.

[0070] In this embodiment, the second light-emitting unit 11 is arranged along the bottom of the first limiting groove 5 of the base 2; the light emitted by the first light-emitting unit 10 is white, and the light emitted by the second light-emitting unit 11 is blue.

[0071] An annular light-transmitting member 13 adapted to the first limiting groove 5 is fixedly provided directly above the second light-emitting unit 11; the second light-emitting unit 11 and the first light-emitting unit 10 cooperate with each other to adjust the hue of the light finally emitted by the atmosphere lamp.

[0072] In this embodiment, the built-in power supply 12 is fixedly arranged in the inner cavity of the connecting member 9, and its bottom is connected with the fourth limiting groove 8 in a matching manner.

[0073] The built-in power supply 12 is used to supply power to the circuit structure inside the atmosphere lamp including the first light-emitting unit 10; installing the built-in power supply 12 in the inner cavity of the connecting member 9 can improve the utilization rate of the internal space of the atmosphere lamp.

[0074] Both the inner lamp cover 3 and the outer lamp cover 4 are cylindrical structures with a hollow interior and open ends at both ends.

[0075] In this embodiment, the inner lamp cover 3 includes a first inner cover 3-1 and a second inner cover 3-2. The first inner cover 3-1 is sleeved in the inner cavity of the second inner cover 3-2; both the first inner cover 3-1 and the second inner cover 3-2 are connected with the first limiting groove 5 in a matching manner. Among them, the inner diameter of the first inner cover 3-1 is the same as the inner diameter of the first limiting groove 5, the outer diameter of the second inner cover 3-2 is the same as the outer diameter of the first limiting groove 5, and the bottoms of both the first inner cover 3-1 and the second inner cover 3-2 are in contact with the light-transmitting member 13. A gap 3-3 is formed between the first inner cover 3-1 and the second inner cover 3-2.

[0076] Although the light guide plate has high light guide performance, it still causes light attenuation, resulting in uneven distribution of the second light-emitting unit 11 on the upper and lower sides of the inner lamp cover 3. By providing the mutually nested first inner cover 3-1 and second inner cover 3-2, the light emitted by the second light-emitting unit 11 passes through the light-transmitting member 13 and is uniformly concentrated in the area of the gap 3-3, and then is scattered and emitted from the sides of the first and second inner covers, and is more uniformly mixed with the light emitted by the first light-emitting unit 10.

[0077] In this embodiment, a limiting rib 4-1 in the form of an annular protrusion is provided along the opening edge of the outer lamp cover 4; the limiting rib 4-1 cooperates with the second limiting groove 6. Among them, the limiting rib 4-1 has a convex-shaped contour in the longitudinal section of the outer lamp cover 4; the second limiting groove 6 has a concave-shaped contour in the longitudinal section of the upper cover 1; when the limiting rib 4-1 and the second limiting groove 6 are connected in cooperation, a smooth transition connection is formed among the outer side walls of the upper cover 1, the base 2, and the outer lamp cover 4.

[0078] The setting of the concave-shaped contour of the second limiting groove 6 and the convex-shaped contour of the limiting rib 4-1 enables the side surface of the atmosphere lamp to remain a smooth curve when the upper cover 1 is connected to the outer lamp cover 4 and the base 2 is connected to the outer lamp cover 4, avoiding the appearance of uneven features and maintaining the aesthetic appearance.

[0079] Through the connecting member 9, the upper cover 1 and the base 2 can be relatively connected to a fixed position, and the three can be fixedly connected by at least two screws. The inner lamp cover 3 is clamped between the two first limiting grooves 5 of the upper cover 1 and the outer lamp cover 4 is clamped between the two second limiting grooves 6 of the upper cover 1 and the base 2, which not only facilitates the loading and unloading of the lamp but also ensures the stability of the connection.
