[0032] The following describes in detail embodiments of the present invention, which are illustrative only with reference to the accompanying drawings.

[0033] Reference below Figures 1-8 The lighting lamp 100 according to the embodiment of the present invention is described, which can achieve anti-glare and anti-dazzle effects during use by the user, and the overall ambient light is more uniform.

[0034] Combine Figures 1-8As shown, the lighting lamp 100 for a study table according to the first embodiment of the present invention includes a housing 1, an upper light-emitting element 2, and a lower light-emitting assembly 3. The housing 1 mainly serves as a structural component of the outer contour of the lighting lamp 100, and can be used to protect the internal components and provide installation and fixing conditions for the internal components; the upper light-emitting element 2 is located in the upper part of the interior of the housing 1, and can be used to provide top lighting, thereby changing the light distribution above the lighting lamp 100 and thereby reducing glare; the lower light-emitting assembly 3 is located in the lower part of the interior of the housing 1, and can be used to provide bottom lighting, thereby facilitating the lighting enhancement effect for users in specific areas, thereby facilitating the users' daily life, study, and work.

[0035] Among them, the lighting lamp in this embodiment can be a large street lamp for a study table (rather than a traditional desk lamp). The large street lamp can have a vertically arranged support rod, the top of the support rod is connected to the shell 1, and the bottom of the support rod is provided with a base, which is set on the ground. In this way, the large street lamp can be located as a whole on the outside of the study table, which can facilitate its position adjustment to meet the specific usage needs of the user. Alternatively, the large street lamp can have a vertically arranged support rod, the top of the support rod is connected to the shell 1, and the bottom of the support rod is connected to the table body of the study table. In this way, the large street lamp is integrated with the table body of the study table, which can ensure the stability of the large street lamp, and the base can be omitted, making the structure of the study table simpler.

[0036] Specifically, an upper opening 11 is provided at the top of the shell 1, and a lower opening 12 is provided at the bottom of the shell 1. The upper light-emitting component 2 is installed on the top side of the inside of the shell 1, and the upper light-emitting component 2 is arranged opposite to the upper opening 11 up and down for emitting light upward. The lower light-emitting component 3 includes a lower light-emitting component 31 and a light guide plate 32. The lower light-emitting component 31 is arranged on the bottom side of the inside of the shell 1, and the lower light-emitting component 31 extends along the circumference of the shell 1. The light guide plate 32 is arranged opposite to the lower opening 12 up and down. The lower light-emitting component 31 surrounds the outer periphery of the light guide plate 32 for emitting light downward from the circumference of the light guide plate 32.

[0037] Specifically, in the up and down directions, the top and bottom of the shell 1 are respectively provided with an upper opening 11 and a lower opening 12. The light emitted by the upper light-emitting component 2 can pass through the upper opening 11 to illuminate the top side of the shell 1, thereby achieving the effect of top lighting; the light emitted by the lower light-emitting component 31 surrounding the outer periphery of the light guide plate 32 can be guided by the light guide plate 32 and pass through the lower opening 12 to illuminate the bottom of the shell 1, thereby achieving the effect of bottom lighting.

[0038] In summary, when the upper light-emitting component 2 and the lower light-emitting component 31 emit light at the same time, the upper light-emitting component 2 can enhance the brightness of the ambient light above the shell 1, and can also make the ambient light more uniform and soft, thereby reducing the ambient shadow when the lower light-emitting component 31 performs bottom lighting on the user, and can also have an anti-glare effect on the user, thereby improving the user's visual comfort.

[0039] Therefore, by providing the lighting lamp 100 , it can achieve anti-glare and anti-dazzling effects during use by the user, and the overall ambient light is more uniform, thereby improving the user experience.

[0040] According to some optional embodiments of the present invention, combined with Figure 3-Figure 5 As shown, the lower light emitting assembly 3 further includes a total reflection layer 33 , which is disposed on the upper surface of the light guide plate 32 for completely reflecting the incident light.

[0041] Among them, the total reflection layer 33 can completely reflect the incident light back (that is, it will not allow the incident light to penetrate or be absorbed). Therefore, the arrangement of the total reflection layer 33 is set on the upper surface of the light guide plate 32. In this way, the light irradiated by the lower light-emitting element 31 surrounding the outer periphery of the light guide plate 32 onto the total reflection layer 33 can be completely reflected to the bottom of the total reflection layer 33, thereby avoiding the invalid brightness loss of the lower light-emitting element 31 (for example, the light emitted by the lower light-emitting element 31 passes upward through the light guide plate 32 or is absorbed by the light guide plate 32), thereby improving the lighting efficiency.

[0042] According to some optional embodiments of the present invention, combined with Figure 3-Figure 5 As shown, the lower light emitting assembly 3 further includes an optical processing portion 34 , which is disposed on the lower surface of the light guide plate 32 . The optical processing portion 34 is one of a prism plate and a PC board with a frosted layer.

[0043] Among them, since the optical processing part 34 is located on the lower surface of the light guide plate 32, the optical processing part 34 can further process the light passing through the light guide plate 32, thereby improving the guiding processing effect of the lower light-emitting component 3 on the light irradiation direction and irradiation range.

[0044] Optionally, the optical processing unit 34 is a prism plate. A prism plate is an optical element (a transparent plate with a tiny prism structure) that is typically used to control and guide the direction of light. Specifically, when the prism plate is positioned on the lower surface of the light guide plate 32, it can be used to guide light emitted from the light guide plate 32 downward, thereby making the reflected light more concentrated and brighter, thereby effectively improving lighting efficiency.

[0045] Alternatively, the optical processing part 34 is a PC board with a frosted layer. The PC board (polycarbonate) is a transparent thermoplastic with high impact strength, good light transmittance (light transmittance can reach more than 88%) and weather resistance. The surface of the PC board is formed with a frosted layer (that is, a rough surface formed on the surface of the PC board by physical or chemical methods). The frosted layer can diffusely reflect the incident light, reduce glare, and provide a soft lighting effect, thereby improving the user's visual comfort.

[0046] That is to say, by arranging the optical processing part 34 as a PC board with a frosted layer, a high degree of reflection of the incident light can be achieved, reducing light loss, and it can also help to control the direction and distribution of light (such as emitting the incident light to the designated area that needs illumination), thereby improving light utilization efficiency and lighting efficiency; and the surface of the PC board is formed with a frosted layer. Such an arrangement can cause the incident light to be diffusely reflected (rather than specularly reflected), thereby reducing glare and improving visual comfort; it can also make the light more evenly distributed, avoiding local overbrightness or overdarkness, thereby providing a softer and more uniform lighting effect.

[0047] In detail, combined Figure 1 and Figure 3 As shown, the lower light-emitting assembly 3 further includes a diffusion film 35, which is disposed on at least one side surface of the optical processing portion 34. The primary function of the diffusion film 35 is to scatter light. In this embodiment, the diffusion film 35 is disposed along the light transmission path. This allows for a more even distribution of light (the diffusion film 35, through its internal microstructure or added diffusion particles, scatters concentrated light into a more uniform beam, eliminating hot spots and dark areas, and providing a uniform lighting effect). It also reduces glare (scattering light effectively reduces glare caused by direct light) and improves light efficiency (scattering allows the light to better cover the entire lighting area, increasing light utilization), thereby effectively enhancing lighting quality and visual comfort.

[0048] Specifically, combined Figure 4 and Figure 5 As shown, the lower light-emitting element 31 includes a plurality of light bars 311 , which are respectively mounted on the side walls of the housing 1 , and each side of the light guide plate 32 corresponds to at least one light bar 311 .

[0049] It can be understood that multiple light strips 311 are respectively installed on the side walls of the shell 1 along the circumferential direction, which can facilitate the individual maintenance and replacement of a single light strip 311, avoid the overall replacement of the light strip 311, and thus reduce the maintenance and replacement costs; and by installing multiple light strips 311 on the circumferential side walls of the shell 1, the overall lighting coverage area and light brightness of the lower light-emitting component 31 can be effectively improved, thereby improving the lighting uniformity and lighting efficiency of the lower light-emitting component 31.

[0050] According to some optional embodiments of the present invention, combined with Figure 1-Figure 5 As shown, the upper light emitting member 2 is in the shape of an elongated strip, and the length direction of the upper light emitting member 2 and the length direction of the upper opening 11 are the same as the length direction of the housing 1 .

[0051] Specifically, as arranged above, the upper opening 11 can be formed with a longer opening size in the limited space of the shell 1, so as to match the longer upper light-emitting component 2. This can effectively improve the lighting coverage range of the upper light-emitting component 2 and improve the uniformity of the ambient light, thereby achieving anti-glare and uniform ambient light effects.

[0052] In addition, such an arrangement can also make the arrangement positions between the upper light-emitting element 2 and the housing 1 more scientific and orderly, thereby improving the rationality of the design.

[0053] Optionally, the upper light-emitting element 2 includes a lamp plate and lamp beads. The lamp plate is constructed in a flat plate shape and is arranged vertically opposite the upper opening 11. The lamp beads are arranged on the upper surface of the lamp plate. Since the flat plate shape can provide a large surface area without occupying excessive weight, the flat plate structure of the lamp plate can provide a large supporting force area for the lamp beads, thereby improving the force stability of the lamp beads and ensuring normal lighting operation of the lamp beads. The lamp beads can be LED lamp beads.

[0054] According to some optional embodiments of the present invention, combined with Figure 1 、 Figure 3 and Figure 4 As shown, along the width direction of the shell 1, the upper light-emitting element 2 is located on the side of the top side of the shell 1 close to the user. Such an arrangement allows the upper light-emitting element 2 to concentrate on emitting light to the upper environment on the top side of the shell 1 close to the user side, effectively avoiding the risk of uneven illumination angles of the ambient light on the user side and improving the brightness of the ambient light on the user side, thereby improving the illumination uniformity and brightness of the ambient light on the user side, and further having the effect of anti-glare and improving visual comfort for the user.

[0055] Optionally, along the length direction of the shell 1, the upper light-emitting component 2 is located in the middle of the top side of the shell 1. Such an arrangement can make the light distribution more symmetrical, so that the upper light-emitting component 2 can provide more uniform top lighting, thereby helping to reduce shadows and uneven lighting and improve the user's visual comfort.

[0056] According to some optional embodiments of the present invention, combined with Figure 1 and Figure 3 As shown, the upper opening 11 and the lower opening 12 are both rectangular. Since the rectangle is a standard symmetrical shape, such an arrangement can facilitate the processing and manufacturing of the upper opening 11 and the lower opening 12, thereby improving manufacturability; it can also more effectively utilize the internal space, thereby improving the rationality of the arrangement.

[0057] Optionally, the projection area of the upper opening 11 on the horizontal plane is S1, the projection area of the lower opening 12 on the horizontal plane is S2, and S1 and S2 satisfy the relationship: 0.1S2<S1<0.5S2.

[0058] The upper opening 11 has a relatively small horizontal projection area S1. This allows the light emitted by the upper light-emitting element 2 to pass through the upper opening 11 for top lighting, while also ensuring that the upper opening 11 does not occupy too much of the opening area on the top of the housing 1, thereby ensuring the overall structural strength of the housing 1. The lower opening 12 has a relatively large horizontal projection area S2. This effectively enhances the illumination range and illumination uniformity of the light from the light-emitting element passing through the lower opening 12, thereby improving the user's visual comfort. For example, the upper opening 11 may have a horizontal projection area S1 of 0.2S2, 0.3S2, or 0.4S2, but is not limited thereto.

[0059] According to some optional embodiments of the present invention, combined with Figure 3 、 Figure 6-Figure 8 As shown, the lighting lamp 100 of the study table also includes a controller 4, which is installed inside the shell 1. The controller 4 is electrically connected to the upper light-emitting part 2 and the lower light-emitting part 31 respectively to control the opening and closing of the upper light-emitting part 2 and / or the lower light-emitting part 31.

[0060] Specifically, the shell 1 can protect the controller 4 inside it and prevent it from being interfered with by external structures, thereby improving its safety. It can also provide a fixed installation position for the controller 4, thereby improving the installation stability of the controller 4.

[0061] Furthermore, the controller 4 is connected to the upper light-emitting component 2 and the lower light-emitting component 31 respectively in the form of electrical signals. The controller 4 mainly controls and coordinates the opening and closing of the upper light-emitting component 2 and / or the lower light-emitting component 31, thereby improving the opening and closing accuracy and sensitivity of the upper light-emitting component 2 and the lower light-emitting component 31.

[0062] For example, the controller 4 can control the upper light emitting element 2 or the lower light emitting element 31 to emit light separately according to user needs, and can also allow the upper light emitting element 2 and the lower light emitting element 31 to emit light at the same time.

[0063] Optionally, combined Figure 2 、 Figure 3 、 Figure 6-Figure 8 As shown, the lighting lamp 100 also includes a seating sensing module 5, which is installed inside the housing 1 and is used to sense a user seating signal. The controller 4 is electrically connected to the upper light-emitting element 2, the lower light-emitting assembly 3 and the seating sensing module 5, respectively, to selectively control the upper light-emitting element 2 and the lower light-emitting assembly 3 to emit light according to the user seating signal sensed by the seating sensing module 5.

[0064] Among them, the seating sensing module 5, the upper light-emitting element 2 and the lower light-emitting component 3 are respectively connected to the controller 4 in the form of electrical signals. In this way, on the one hand, the upper light-emitting element 2 and the lower light-emitting component 3 can respond to the control command signal of the controller 4 in a timely and accurate manner. On the other hand, the user seating signal detected by the seating sensing module 5 can be fed back to the controller 4 in real time to selectively make the upper light-emitting element 2 and the lower light-emitting component 3 emit light, thereby achieving the effect of automatically adjusting the lighting of the upper light-emitting element 2 and the lower light-emitting component 3 according to the detected user seating signal, thereby improving the intelligence of the lighting lamp 100.

[0065] Further, combined with Figure 2 、 Figure 3 、 Figure 6-Figure 8 As shown, the housing 1 includes a frame 13 and a mounting plate 14. The mounting plate 14 is connected to the middle of the front side of the frame 13 and protrudes backward. The mounting plate 14 is provided with a mounting hole, and the seat sensing module 5 is installed in the mounting hole.

[0066] That is to say, the frame 13 is mainly constructed as a structural member extending along the circumferential direction, and the mounting plate 14 is connected to the frame 13, so that the frame 13 can provide installation support conditions for the mounting plate 14. The mounting plate 14 protrudes backward in the frame 13, and the occupancy sensing module 5 can be installed in the mounting hole on the mounting plate 14, so that the occupancy sensing module 5, the mounting plate 14 and the frame 13 are connected as a whole, which can ensure the installation stability of the occupancy sensing module 5.

[0067] Specifically, combined Figure 3 、 Figure 6-Figure 8 As shown, the light guide plate 32 is installed on the frame 13 , the lower light emitting element 31 surrounds the outer periphery of the light guide plate 32 , the light guide plate 32 is provided with a notch 321 , and the mounting plate 14 is correspondingly located at the notch 321 .

[0068] It can be understood that the light guide plate 32 is provided with a through-ground notch 321 in the up and down directions. The notch 321 can avoid the mounting plate 14 and match the shape of the mounting plate 14. This can ensure the flatness of the outer contour of the shell 1 and avoid the shell 1 from extending outward with unnecessary structure, thereby improving the rationality of the layout of the lighting lamp 100.

[0069] Optionally, combined Figure 1 、 Figure 3 and Figure 6 As shown, the lighting lamp 100 also includes a diffuser 15, which is located above the upper light-emitting component 2, and the diffuser 15 and the upper light-emitting component 2 are arranged relative to each other. The main function of the diffuser 15 is to scatter light, so that the distribution of light emitted by the upper light-emitting component 2 can be more uniform, thereby improving the lighting effect of the upper light-emitting component 2.

[0070] The study table according to the embodiment of the second aspect of the present invention includes the lighting lamp 100 of the study table of the above embodiment. The study table with the lighting lamp 100 can have an anti-glare effect during the user's use, and the overall ambient light is more uniform and soft, thereby effectively improving the user's visual comfort and further improving the market competitiveness of the study table.
