[0002] Existing baked food lighting mainly relies on efficient and energy-saving light sources, such as LED (light-emitting diode) light sources. The functional design requirements of baked food lighting are mainly reflected in three aspects: lighting effect, anti-glare design and high focusing ability. Among them, lighting effect mainly refers to the ability of the lighting device to provide sufficient and uniform light to meet the lighting needs of different areas in the bakery, and the product display area requires higher illumination and better color reproduction to highlight the product features; anti-glare design refers to the need for the lighting device to adopt appropriate shading angles, anti-glare accessories or lampshade designs to avoid glare caused by direct light to the human eye and improve the visual comfort of customers; high focusing ability refers to the lighting device's focusing ability to ensure that the lighting device can project light to the differences that need to be highlighted.

[0003] At present, the lighting device for baked food mainly includes an inner ring shell, an outer ring shell, a heat sink and a lighting assembly. One end of the inner ring shell is connected to the heat sink, and the other end is sleeved with an outer ring shell. The outer ring shell is provided with a number of spring clips. The lighting assembly is located in the inner ring shell, and the lighting assembly is connected to the heat sink. The lighting assembly mainly includes a light source and a lens. Among them, the outer ring shell can be installed on the ceiling through an elastic clip, the heat sink is used to achieve heat dissipation of the lighting assembly, and the light source and lens are used to generate light to achieve the lighting function. In order to achieve the anti-glare function, the existing lighting devices usually adopt a deep cup anti-glare design, that is, by increasing the depth of the light source in the inner ring shell, the shading angle is increased to achieve the anti-glare function.

[0004] The light source of the existing lighting device is fixed in the inner ring shell, which makes the shielding angle of the lighting device fixed, so the anti-glare ability of the lighting device is fixed. In actual applications, different installation locations and usage environments have different requirements for the anti-glare ability of the lighting device. However, the anti-glare ability of the existing lighting device is difficult to meet the requirements of different installation locations and different usage environments. Summary of the invention

[0005] The present application provides a lighting device for baked food, the purpose of which is to be able to adjust the position of the light source in the inner ring shell, and then to be able to freely adjust the shading angle of the lighting device according to actual needs, so that the anti-glare ability of the lighting device can be adjusted, and then the anti-glare ability of the lighting device can meet the requirements of different installation positions and different usage environments.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 -Attached Figure 6 , further details of this application are given.

[0039] Embodiment 1: A lighting device for baked food, referring to Figure 1and Figure 2 , including an inner ring shell 1, a heat sink 2, a lighting mechanism 3 and an outer ring shell 4, one end of the inner ring shell 1 is detachably connected to the heat sink 2, and the other end is plugged with the outer ring shell 4, and the outer ring shell 4 is detachably connected to the inner ring shell 1, and the lighting mechanism 3 is arranged in the inner ring shell 1, and the lighting mechanism 3 is connected to the heat sink 2. The heat sink 2 realizes the heat dissipation of the lighting device, the lighting mechanism 3 realizes the lighting function, and the setting of the outer ring shell 4 can realize the installation of the lighting device, and the lighting function can be realized through the cooperation of the inner ring shell 1, the heat sink 2, the lighting mechanism 3 and the outer ring shell 4.

[0040] Reference Figure 2 and Figure 3 The radiator 2 includes a heat sink 21, which is plugged into one end of the inner ring shell 1 and connected to the inner ring shell 1 by bolts. A plurality of heat sinks 22 are arranged on the side of the heat sink 21 away from the inner ring shell 1. The heat sink 21 and the heat sink 22 cooperate to achieve heat dissipation.

[0041] Reference Figure 2 and Figure 3 The lighting mechanism 3 includes a light source 31, a reflective cup 32 and a lens 33. The light source 31 is mounted on the heat sink 21. The reflective cup 32 is axially arranged along the axial direction of the inner ring shell 1. One end of the reflective cup 32 is connected to the heat sink 21. The other end of the reflective cup 32 is sleeved on the outside of the lens 33. The lens 33 seals the reflective cup 32. The light source 31 is located inside the reflective cup 32. The lighting mechanism 3 can emit light and realize the lighting function through the cooperation of the light source 31, the reflective cup 32 and the lens 33.

[0042] Reference Figure 1 and Figure 2 The inner ring shell 1 includes a first ring shell 11 and a second ring shell 12. The first ring shell 11 is sleeved on the outside of the second ring shell 12, and the first ring shell 11 is slidably connected to the second ring shell 12 along its own axial direction.

[0043] Reference Figure 3 The heat sink 21 is disposed at one end of the first annular shell 11 away from the second annular shell 12, and the heat sink 21 is detachably connected to the first annular shell 11. The outer annular shell 4 is sleeved at one end of the second annular shell 12 away from the first annular shell 11, and the outer annular shell 4 is connected to the second annular shell 12 by bolts. The lighting mechanism 3 is located in the first annular shell 11, and the second annular shell 12 is located between the inner wall of the first annular shell 11 and the outer wall of the reflective cup 32.

[0044] The length of the inner ring shell 1 can be adjusted by sliding the first ring shell 11 and the second ring shell 12. When the depth of the inner ring shell 1 increases, the distance between the light source 31 and the outer ring shell 4 increases, which can increase the shading angle, thereby achieving the deep cup anti-glare function. Since the length of the inner ring shell 1 is not fixed, the length of the inner ring shell 1 can be adjusted according to requirements, thereby making the anti-glare ability of the lighting device of the present application meet different requirements, which can improve the scope of application of the lighting device of the present application.

[0045] Reference Figure 3 The inner wall of the first ring shell 11 is spaced apart from the outer wall of the second ring shell 12. Such a structural arrangement ensures that the first ring shell 11 and the second ring shell 12 can slide and rotate relative to each other.

[0046] Reference Figure 3 The second ring shell 12 is sleeved with a driving ring 5, which is connected to the second ring shell 12 by threads, and is connected to the first ring shell 11. When the driving ring 5 rotates, the driving ring 5 moves along the axial direction of the second ring shell 12 under the action of the threaded connection, and then the driving ring 5 drives the first ring shell 11 to move along its own axial direction.

[0047] Reference Figure 3 and Figure 4 The first ring shell 11 is sleeved on the outside of the driving ring 5, and the driving ring 5 is located between the inner wall of the first ring shell 11 and the outer wall of the second ring shell 12. A limiting ring 51 is sleeved on the outer wall of the driving ring 5, and the limiting ring 51 is fixedly connected to the driving ring 5, and one end of the first ring shell 11 abuts against the limiting ring 51. The setting of the limiting ring 51 can limit the first ring shell 11.

[0048] Reference Figure 3 and Figure 4 A plurality of driving grooves 52 are provided on the outer wall of the driving ring 5. The plurality of driving grooves 52 are evenly spaced in sequence along the circumference of the driving ring 5. The length direction of the driving grooves 52 is arranged along the axial direction of the driving ring 5. The driving grooves 52 penetrate the side of the driving ring 5 facing the radiator 2 along its own length direction. The inner wall of the driving grooves 52 away from the radiator 2 along its own length direction is flush with the side wall of the limiting ring 51 facing the radiator 2. A plurality of driving blocks 111 are provided on the inner wall of the first ring shell 11. The plurality of driving blocks 111 are evenly spaced in sequence along the circumference of the first ring shell 11. The driving blocks 111 are arranged one by one in correspondence with the driving grooves 52, and the driving blocks 111 are plugged and matched with the corresponding driving grooves 52. The driving blocks 111 are slidably connected with the inner wall of the corresponding driving groove 52 along the axial direction of the driving ring 5.

[0049] When the driving blocks 111 on the first ring shell 11 are all plugged into the corresponding driving grooves 52 , the driving ring 5 can be driven by rotating the first ring shell 11 , and then the driving ring 5 can drive the first ring shell 11 to move along its own axial direction.

[0050] Reference Figure 4 , a plurality of limiting long grooves 53 are also provided on the outer wall of the driving ring 5, and the plurality of limiting long grooves 53 are arranged in sequence and at intervals along the circumference of the driving ring 5, and the length direction of the limiting long grooves 53 is arranged along the circumference of the driving ring 5. The limiting long grooves 53 are arranged one by one with the driving grooves 52, and the side of the driving groove 52 away from the heat sink 2 along its own length direction is connected to the middle of the corresponding limiting long groove 53. In addition, the driving block 111 is plug-fitted with the corresponding limiting long groove 53, and the driving block 111 is slidably connected with the inner wall of the corresponding limiting long groove 53 along the circumference of the driving ring 5.

[0051] Reference Figure 4 Since the driving block 111 can easily slide out from the corresponding driving groove 52, after the driving block 111 is inserted into the corresponding driving groove 52, the first ring shell 11 is rotated so that several driving blocks 111 are inserted into the corresponding limiting long grooves 53. At this time, the limiting long grooves 53 can limit the driving block 111 along the axial direction of the driving ring 5, which makes it difficult for the driving block 111 to slide out. Therefore, this can improve the stability of the connection between the driving ring 5 and the first ring shell 11.

[0052] Reference Figure 4 When the first ring shell 11 is required to drive the driving ring 5 to rotate, the first ring shell 11 is first rotated clockwise so that the plurality of driving blocks 111 can all contact the inner side wall of the corresponding limiting long groove 53, and then the first ring shell 11 is continued to be rotated clockwise. At this time, under the contact of the plurality of driving blocks 111, the driving ring 5 will rotate, and then the driving ring 5 drives the first ring shell 11 to move along its own axial direction. On the contrary, when the first ring shell 11 is rotated counterclockwise and the plurality of driving blocks 111 contact the inner side wall of the corresponding limiting long groove, the first ring shell 11 is continued to be rotated counterclockwise, and the first ring shell 11 can be driven to move in the opposite direction along its own axial direction.

[0053] Reference Figure 4 A first long hole 112 is formed on the outer wall of the first ring shell 11. The length direction of the first long hole 112 is arranged along the axial direction of the first ring shell 11. The first long hole 112 passes through the first ring shell 11 along its own length direction toward the side of the limiting ring 51. A second hole 54 is formed on the outer wall of the driving ring 5.

[0054] Reference Figure 4When the first ring shell 11 and the driving ring 5 rotate relative to each other, when the plurality of driving blocks 111 move to the middle of the corresponding limiting long groove 53 and the driving blocks 111 are aligned with the corresponding driving groove 52, the first long hole 112 is connected to the second hole 54. In this state, the first ring shell 11 is moved along its own axial direction in a direction away from the driving ring 5, and the plurality of driving blocks 111 can be inserted into the corresponding driving groove 52, so that the driving blocks 111 can slide in the corresponding driving groove 52, thereby realizing the disassembly of the first ring shell 11 and the driving ring 5.

[0055] The first long hole 112 and the second hole 54 are arranged in cooperation, so as to indicate the position of the driving block 111, and facilitate the disassembly of the driving ring 5 and the first ring shell 11. Moreover, when the first long hole 112 and the second hole 54 are connected, a bolt is inserted into the second hole 54, and at this time, the bolt and the first long hole 112 are also plugged and matched, which can prevent the first ring shell 11 and the driving ring 5 from rotating relative to each other, and thus facilitate the disassembly of the first ring shell 11 and the driving ring 5.

[0056] Reference Figure 2 and Figure 3 The second ring shell 12 is coaxially plugged with a coated thin ring 6, the coated thin ring 6 is coaxially arranged with the second ring shell 12, and the outer wall of the coated thin ring 6 is in contact with the inner wall of the second ring shell 12, and the coated thin ring 6 is detachably connected with the second ring shell 12. The reflective cup 32 is located in the coated thin ring 6, and the outer wall of the reflective cup 32 is spaced apart from the inner wall of the coated thin ring 6. The inner wall of the coated thin ring 6 is coated with a reflective coating, and the inner wall of the second ring shell 12 is coated with a black coating.

[0057] When the coated thin ring 6 is installed in the second ring shell 12, the reflective coating can reflect the light emitted by the light source 31, thereby ensuring the lighting brightness of the lighting device. When the coated thin ring 6 in the second ring shell 12 is removed, the black coating will absorb the stray light and scattered light emitted by the light source 31, thereby increasing the anti-glare function of the lighting device. Such a structural setting can improve the scope of application of the lighting device of the present application.

[0058] Reference Figure 2 and Figure 3 The second ring shell 12 is embedded with a magnetic ring, and the magnetic ring is coaxially arranged with the second ring shell 12. The coating thin ring 6 is made of a magnet or other material that can be adsorbed by a magnet. The coating thin ring 6 can be adsorbed inside the second ring shell 12 through the magnetic ring, which can improve the stability of the connection between the coating thin ring 6 and the second ring shell 12.

[0059] Reference Figure 2 and Figure 3The second ring shell 12 is provided with an anti-glare member 7 at one end away from the radiator 2. The anti-glare member 7 includes a mounting ring 71 and an anti-glare net 72.

The anti-swirl net is located inside the mounting ring 71, and the circumference of the anti-glare net 72 is fixedly connected to the inner side wall of the mounting ring 71. The provision of the anti-glare net 72 can improve the anti-glare function of the lighting device.

[0060] The implementation principle of the embodiment of the present application is as follows: after the lighting device is assembled, according to the installation position requirements of the lighting device, the first ring shell 11 is rotated so that the first ring shell 11 drives the driving ring 5 to rotate, and then the length of the inner ring shell 1 is adjusted so that the depth of the light source 31 in the inner ring shell 1 can meet the anti-glare requirements of the lighting device. In addition, according to actual requirements, the coating thin ring 6 and the anti-glare member 7 are selected and installed to ensure that the brightness and anti-glare ability of the lighting device can meet the requirements.

[0061] Embodiment 2: A lighting device for baked food, referring to Figure 5 and Figure 6 The difference between this embodiment and embodiment 1 is that a conversion ring 8 is coaxially arranged on the side of the first ring shell 11 facing the driving ring 5, the conversion ring 8 is sleeved on the outside of the driving ring 5, and the conversion ring 8 is located between the first ring shell 11 and the limit ring 51 along its own axial direction, and the conversion ring 8 is in conflict with the first ring shell 11 and the limit ring 51 on both axial sides.

[0062] Reference Figure 5 and Figure 6 The drive ring 5 is plugged and matched with the conversion ring 8, and the conversion ring 8 is rotatably connected with the drive ring 5 along its own circumferential direction. The plurality of drive blocks 111 are all located on the inner side wall of the conversion ring 8, and the first long hole 112 is provided on the conversion ring 8. Such a structural arrangement enables the drive ring 5 to be detachably connected with the conversion ring 8, and the drive ring 5 can be driven by rotating the conversion ring 8.

[0063] Reference Figure 5 and Figure 6 The first ring housing 11 is rotatably connected to the conversion ring 8. Specifically, the first ring housing 11 is connected to the conversion ring 8 via a slewing bearing.

[0064] Reference Figure 6 An axial guide mechanism 9 is provided between the first annular shell 11 and the second annular shell 12. The axial guide mechanism 9 includes a guide ring 91. The guide ring 91 is coaxially arranged with the second annular shell 12 and is arranged on the side of the second annular shell 12 facing the radiator 2. The guide ring 91 is detachably connected to the second annular shell 12. Specifically, the guide ring 91 is connected to the second annular shell 12 by bolts. A plurality of guide blocks 92 are provided on the outer wall of the guide ring 91.

Then, when the conversion ring 8 drives the driving ring 5 to rotate, the driving ring 5 moves along its own axial direction, and the driving ring 5 drives the conversion ring 8 to move along its own axial direction. At this time, the conversion ring 8 and the first ring shell 11 rotate relative to each other, and then the conversion ring 8 resists the first ring shell 11 to move along its own axial direction, which can realize the adjustment of the length of the inner ring shell 1.
