Description

Technical Field

[0001] This utility model relates to the field of sewing machine lighting technology, specifically to a reflective single-sided lighting system and a sewing machine. Background Technology

[0002] Current sewing machines use sewing machine lights for illumination, but these lights shine directly into the eyes, which can damage the eyes and interfere with the sewing work.

[0003] Patent document CN212361796U discloses an intelligent sewing machine reverse-sewing switch LED light. This reverse-sewing switch LED light mounts the light source directly below the machine head and uses a soft-light cover to soften the light, preventing direct eye contact and ensuring the efficiency of the sewing worker's work. However, in actual use, due to the reflective surface of the sewing machine table, some of the light hitting the table surface is reflected and shines directly into the eyes, still causing damage to the worker's eyes and affecting their sewing work.

[0004] Therefore, how to avoid direct sunlight shining into the eyes and ensure the efficiency of sewing operations has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a reflective unilateral lighting system to address the above-mentioned technical problems.

[0006] The technical solution adopted in this utility model is: a reflective single-sided lighting system, comprising:

[0007] Main assembly;

[0008] A reflector, wherein the reflector is disposed on one side of the main assembly and fixedly connected to the bottom end of the main assembly;

[0009] A diffuser cover is disposed below the reflector and fixedly connected to the main body assembly;

[0010] A light-emitting element is disposed between the diffuser cover and the reflector.

[0011] The soft light cover has a light-transmitting area, and the light-emitting body is located at the end of the light-transmitting area closer to the person.

[0012] Preferably, the soft light cover is provided with a light-transmitting area and a light-shielding area, the light-shielding area is arranged around the light-transmitting area, and the light-emitting body is located directly above the light-shielding area.

[0013] Preferably, the soft light cover is provided with a light-transmitting area and a light-shielding area, the light-shielding area is located at the near end of the light-transmitting area, and the light-emitting body is located directly above the light-shielding area.

[0014] Preferably, the light-emitting element is inclined toward the far end of the diffuser in the shading area.

[0015] Preferably, the light-shielding area at the near-human end of the soft light cover is formed at an angle.

[0016] Preferably, the longitudinal relative position of the light-transmitting area and the main body assembly is adjustable.

[0017] Preferably, the diffuser cover is slidably connected to the main body assembly in the longitudinal direction.

[0018] Preferably, the light-emitting element is an LED lamp.

[0019] Preferably, the reflector is horizontally positioned directly above the diffuser cover.

[0020] The second objective of this utility model is to provide a sewing machine, which includes the aforementioned reflective single-sided lighting system and a sewing head, wherein the main body assembly is fixedly connected to one side of the sewing head, and the reflector and diffuser cover are located directly below the sewing head.

[0021] The beneficial effects of this utility model are:

[0022] This invention utilizes light reflection. A reflector is installed directly above the diffuser cover, and a light-transmitting area is provided on the diffuser cover. A light-emitting element is positioned between the diffuser cover and the reflector at the near end of the light-transmitting area. The light emitted by the light-emitting element is emitted through the reflector and then exits through the light-transmitting area of ​​the diffuser cover. Since the light-emitting element is located near the near end of the light-transmitting area, the light emitted from the light-transmitting area reflects off the worktable towards the far end of the worktable. In this way, not only is the sewing area on the worktable illuminated, but the light is also prevented from reflecting off the surface of the worktable and shining directly into the eyes, thus avoiding damage to the worker's eyes and ensuring the efficiency of the worker's sewing work.

[0040] Examples, such as Figures 1-6 As shown, a reflective unilateral lighting system includes:

[0041] The main body assembly 10 is fixedly connected to the head 50.

[0042] A reflector 20 is located on one side of the main body assembly 10 and is fixedly connected to the bottom end of the main body assembly 10.

[0043] A diffuser cover 30 is disposed below the reflector 20 and is fixedly connected to the main body assembly 10.

[0044] A light-emitting element 40 is disposed between the diffuser cover 30 and the reflector 20.

[0045] The diffuser cover 30 has a light-transmitting area 31, and the light-emitting body 40 is located at the near end of the light-transmitting area 31 so that the light emitted by the light-emitting body 40 towards the reflector 20 is reflected on the lower surface of the reflector 20 and emitted from the light-transmitting area 31.

[0046] This invention utilizes light reflection. A reflector 20 is installed directly above the diffuser cover 30, and a light-transmitting area 31 is provided on the diffuser cover 30. A light-emitting body 40, located between the diffuser cover 30 and the reflector 20, is positioned at the near end of the light-transmitting area 31. This allows the light emitted from the light-emitting body 40 to pass through the reflector 20 and then exit through the light-transmitting area 31 of the diffuser cover 30. Since the light-emitting body 40 is located at the near end of the light-transmitting area 31, the light emitted from the light-transmitting area 31 will reflect off the table 60 towards the far end of the table 60 after hitting it. In this way, not only is the sewing area on the table 60 illuminated, but the light is also prevented from reflecting off the surface of the table 60 and hitting the eyes, thus avoiding damage to the workers' eyes and ensuring the efficiency of the workers' sewing operations.

[0047] Specific embodiment 1, such as Figures 1-6 As shown, a reflective unilateral lighting system includes: a main body assembly 10, a reflector 20, a diffuser cover 30, and a light emitter 40.

[0048] The main body assembly 10 can be fixedly connected to one side of the machine head 50; for example, the main body assembly 10 can be fixedly connected to the right side of the machine head 50.

[0049] It should be noted that the main assembly 10 is existing technology, and its specific structure can be referred to the reverse-slit switch LED light in CN212361796U.

[0050] The reflector 20 is arranged horizontally on one side of the main body assembly 10 and is fixedly connected to the bottom of the main body assembly 10. For example, the reflector 20 is arranged horizontally on the left side of the main body assembly 10 and the right end of the reflector 20 is fixedly connected to the bottom of the main body assembly 10, so that after the main body assembly 10 is fixedly connected to the machine head 50, the reflector 20 is located directly below the machine head 50.

[0051] The diffuser cover 30 is positioned directly below the reflector 20 with its opening facing upwards, and the diffuser cover 30 is fixedly connected to the main body assembly 10; for example, the right end of the diffuser cover 30 is fixedly connected to the main body assembly 10.

[0052] The light-emitting element 40 is disposed between the diffuser cover 30 and the reflector 20, that is, the light-emitting element 40 is installed in the inner cavity of the diffuser cover 30.

[0053] Preferably, the light-emitting body 40 is an LED lamp.

[0054] The diffuser cover 30 has a light-transmitting area 31. The end of the light-transmitting area 31 that is closer to the staff is the near-person end, and the end of the light-transmitting area 31 that is farther away from the staff is the far-person end. The light-emitting body 40 is located at the near-person end of the light-transmitting area 31, so that the light emitted by the light-emitting body 40 towards the reflector 20 is reflected on the lower surface of the reflector 20 and emitted from the light-transmitting area 31.

[0055] Preferably, the diffuser cover 30 is provided with a light-transmitting area 31 and a light-shielding area 32. The light-transmitting area 31 is located at the bottom of the diffuser cover 30, and the light-shielding area 32 is arranged around the light-transmitting area 31. The light-emitting body 40 is located directly above the light-shielding area 32 to prevent the light emitted by the light-emitting body 40 from directly hitting the table plate 60.

[0056] It should be noted that: the light-transmitting area 31 refers to the area on the soft light cover 30 with a high light transmittance, and the light-blocking area 32 refers to the area on the soft light cover 30 with a low light transmittance or even no light transmittance.

[0057] In other embodiments, a light-transmitting area 31 and a light-shielding area 32 are provided on the light-diffusing cover 30. The light-transmitting area 31 is located at the bottom of the light-diffusing cover 30, and the light-shielding area 32 is located at the near end of the light-transmitting area 31. The light-emitting body 40 is located directly above the light-shielding area 32 to prevent the light emitted by the light-emitting body 40 from directly hitting the table plate 60.

[0058] More preferably, the light source 40 is located at the near end of the light-transmitting area 31, the light source 40 is installed directly above the light-shielding area 32, and the light source 40 is tilted towards the far end of the diffuser cover 30 so that as much light emitted by the light source 40 as possible is directed towards the far end of the diffuser cover 30 and towards the reflector 20.

[0059] Specifically, the light-shielding area 32 at the near-human end of the diffuser cover 30 is formed at an angle so that the light-emitting body 40 is installed at an angle in the inner cavity of the diffuser cover 30.

[0060] The diffuser cover 30 has a clearance slot formed on it to cooperate with the needle bar. The clearance slot makes the diffuser cover 30 U-shaped as a whole. There are two sets of light-emitting elements 40, each set containing at least one LED. The two sets of light-emitting elements 40 are installed one-to-one on the two feet of the diffuser cover 30.

[0061] In other embodiments, the longitudinal relative position of the light-transmitting area 31 and the main body assembly 10 can be adjusted so that the illumination area range of the light emitted from the light-transmitting area 31 on the table 60 can be adjusted by adjusting the relative position of the light-transmitting area 31 and the main body assembly 10 in the longitudinal direction.

[0062] Preferably, the diffuser cover 30 is slidably connected to the main body assembly 10 in the longitudinal direction.

[0063] It should be noted that the sliding connection between the soft light cover 30 and the main body assembly 10 is existing technology and will not be described in detail here.

[0064] It should be noted that in this embodiment, the lateral direction refers to... Figure 2 The single arrow in the diagram indicates the left-right direction of the sewing machine; the vertical direction refers to... Figure 2 The double arrows in the diagram indicate the forward and backward direction of the sewing machine.

[0065] Example 2: A sewing machine including the above-mentioned reflective single-sided lighting system and a sewing head 50, wherein the main body assembly 10 is fixedly connected to the right side of the sewing head 50, and the reflector 20 and the diffuser cover 30 are located directly below the sewing head 50.

[0066] The working principle of this reflective single-sided lighting system is as follows:

[0067] When the reflective single-sided lighting system is working, the light source emits light at an angle upwards. The incident light is reflected on the reflector, and the outgoing light is emitted downwards and forwards. The maximum outgoing angle of the outgoing light is B, and the minimum outgoing angle is A. The maximum outgoing angle B and the minimum outgoing angle A are both less than 90°. This means that the light emitted from the diffuser will be directed towards the far end of the table, which will greatly reduce the light directly hitting the eyes and direct most of the light towards the presser feet and the area in front of the presser feet.

[0068] During the sewing process, assume the width of the sewing table is a, the height from the light plane (the lower surface of the soft light cover) to the upper surface of the sewing table is h; the distance from the needle point to the light on the sewing table is d, the maximum distance from the needle point to the edge of the sewing table near the person is c, c > 0, which is generally to cover the presser foot and the material pressing part, and the maximum distance from the needle point to the edge of the sewing table far from the person is b (generally able to reach the farthest point of the bottom plate).

[0069] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0070] This invention achieves an asymmetrical light path through reflective lighting, resulting in a single-sided lighting effect on the sewing table. This concentrates the light on the sewing area, avoiding direct light into the eyes, reducing eye damage, and ensuring sewing efficiency.

[0071] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
