[0035] The following describes in detail embodiments of the present invention, which are illustrative only with reference to the accompanying drawings.

[0036] Reference below Figures 1-10 The lighting lamp 100 according to the embodiment of the present invention is described, which can improve the heat dissipation effect of the light-emitting component 2, thereby improving the working efficiency and stability of the light-emitting component 2.

[0037] Combine Figures 1-10 As shown, the lighting lamp 100 according to the first embodiment of the present invention includes a housing 1, a light-emitting assembly 2, and a heat sink 3. The housing 1 primarily serves as the structural component of the exterior contour of the lighting lamp 100, protecting the internal components and providing mounting support for the internal components. The light-emitting assembly 2 can be used to provide a light source (i.e., generate light), and can also adjust the brightness and color temperature of the light through circuit design and dimming devices. It can also evenly distribute the light through optical design to reduce glare and shadows. The heat sink 3 is used to dissipate the heat generated by the light-emitting assembly 2 (i.e., transfer the heat generated by the light-emitting assembly 2 to the surrounding environment through conduction, convection, radiation, etc.), thereby maintaining the internal temperature of the housing 1 within a safe range, thereby extending the service life of the light-emitting assembly 2 and improving the operating efficiency and stability of the light-emitting assembly 2.

[0038] For example, the lighting lamp 100 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 pole, the top of the support pole is connected to the shell 1, and the bottom of the support pole 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 pole, the top of the support pole is connected to the shell 1, and the bottom of the support pole 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 can omit the base, making the structure of the study table simpler.

[0039] Specifically, the shell 1 is provided with an upper opening 11 and a lower opening 12, and the light-emitting component 2 is installed on the shell 1. The light-emitting component 2 includes an upper light-emitting part 21 and a lower light-emitting part 22. The upper light-emitting part 21 is arranged opposite to the upper opening 11 up and down for emitting light upward, and the lower light-emitting part 22 is used for emitting light downward. The heat sink 3 is installed in the shell 1, and the heat sink 3 is located below the upper light-emitting part 21 for dissipating heat for the upper light-emitting part 21.

[0040] Specifically, the light emitted by the upper light-emitting component 21 can pass through the upper opening 11 and emit light above the top of the shell 1, so that the top lighting effect of the lighting lamp 100 can be achieved; the light emitted by the lower light-emitting component 22 can pass through the lower opening 12, thereby achieving the bottom lighting effect of the lighting lamp 100. In summary, when the upper light-emitting component 21 and the lower light-emitting component 22 emit light at the same time, the upper light-emitting component 21 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 effect of the ambient shadow when the lower light-emitting component 22 performs bottom lighting on the user, and can also have an anti-glare effect on the user, thereby improving the user's visual comfort.

[0041] Furthermore, the shell 1 can protect the internal radiator 3 and prevent it from being interfered with by external structures; the radiator 3 is located below the upper light-emitting component 21, and it can effectively receive the heat radiated by the upper light-emitting component 21 and conduct the heat to the surrounding environment, thereby effectively dissipating the heat for the upper light-emitting component 21, which can reduce the internal temperature of the upper light-emitting component 21 and ensure that the internal temperature of the upper light-emitting component 21 is within a safe range, thereby extending the service life of the light-emitting component 2 and improving the working efficiency of the light-emitting component 2.

[0042] Therefore, by providing the lighting lamp 100 , the heat dissipation effect of the light emitting component 2 can be improved, thereby improving the working efficiency of the light emitting component 2 .

[0043] According to some optional embodiments of the present invention, combined with Figure 5-Figure 8 As shown, the radiator 3 includes a heat dissipation plate 31 and connecting plates 32 arranged at intervals along the width direction of the shell 1. The heat dissipation plate 31 is located below the upper light-emitting component 21, and the heat dissipation plate 31 and the upper light-emitting component 21 are arranged opposite to each other up and down. The spaced connecting plates 32 are respectively connected to the two ends of the heat dissipation plate 31 in the width direction, and the connecting plates 32 are respectively connected to the shell 1.

[0044] Among them, compared with other shapes, the surface of the heat sink 31 is smoother, and the heat sink 31 can have a larger surface area without occupying too much weight, which can effectively improve the heat dissipation efficiency of the radiator 3; the connecting plates 32 are arranged at intervals along the width direction of the shell 1, and the connecting plates 32 are bent and connected to the heat sink 31. The connecting plates 32 change the structural extension direction of the heat sink 31, which can increase the weight and spatial mode of the heat sink 31, thereby improving the overall structural strength and bending and torsional stiffness of the radiator 3.

[0045] In addition, the heat sink 31 and the upper light-emitting component 21 are arranged relative to each other in an upper and lower direction, so that the heat sink 31 can effectively absorb the heat emitted by the upper light-emitting component 21, and the connecting plate 32 can increase the heat dissipation area of the radiator 3 to a certain extent, thereby effectively improving the heat dissipation effect of the radiator 3; the connecting plate 32 is connected to the shell 1, so that the radiator 3 and the shell 1 can establish a firm connection relationship, thereby improving the installation stability of the radiator 3.

[0046] Optionally, an adapter 4 is provided between the housing 1 and the heat dissipation plate 31 of the radiator 3 . The adapter 4 can indirectly connect the housing 1 and the radiator 3 into a whole, thereby improving the installation stability of the radiator 3 .

[0047] Specifically, combined Figure 5 and Figure 6 As shown, the heat dissipation plate 31 is provided with first heat dissipation holes 311 at intervals along the length direction. The first heat dissipation holes 311 are located directly below the upper light-emitting component 21. With such an arrangement, the heat emitted by the upper light-emitting component 21 can be continuously dissipated to the surrounding space in the shell 1 through the first heat dissipation holes 311, thereby preventing the heat emitted by the upper light-emitting component 21 from being concentrated on the radiator 3 for a long time and causing the risk of the radiator 3 being overheated, thereby improving the continuous heat dissipation effect.

[0048] Further, combined with Figure 5 and Figure 6 As shown, the radiator 3 also includes a heat dissipation reinforcement plate 33, which is arranged directly below the upper light-emitting component 21, and the heat dissipation reinforcement plate 33 is stacked and attached to the upper surface of the heat dissipation plate 31. The heat dissipation reinforcement plate 33 is provided with second heat dissipation holes 331 at intervals along the length direction, and the second heat dissipation holes 331 are connected to the first heat dissipation holes 311.

[0049] That is to say, the heat dissipation reinforcement plate 33 can further increase the heat dissipation area of the heat dissipation plate 31, thereby improving the heat dissipation effect of the radiator 3; the heat dissipation reinforcement plate 33 is provided with second heat dissipation holes 331 connected to the first heat dissipation holes 311 at intervals along the length direction, so that it can also ensure that the heat absorbed by the heat dissipation reinforcement plate 33 can smoothly pass through the second heat dissipation holes 331 and the first heat dissipation holes 311 and then exchange heat with the surrounding space in the shell 1, thereby effectively improving the heat dissipation effect.

[0050] Specifically, combined Figure 5 and Figure 6As shown, the heat sink 31 is connected to the middle of the connecting plate 32 in the up-down direction. Such an arrangement, on the one hand, can make the force distribution between the two more uniform, thereby reducing the risk of deformation damage caused by stress concentration and eccentric load, thereby improving its structural stability; on the other hand, it can also maintain a roughly equal distance between the upper and lower ends of the heat sink 31 and the connecting plate 32, thereby achieving the effect of effectively avoiding related structures in the up-down direction, thereby improving the rationality of its arrangement.

[0051] Further, combined with Figure 5 and Figure 6 As shown, the connecting plate 32 is provided with flanges 321 at the ends in the up-down direction. The flanges 321 are fitted on the corresponding inner surfaces of the shell 1 in the up-down direction, and the flanges 321 are connected to the shell 1 .

[0052] That is to say, the upper and lower ends of the connecting plate 32 are respectively provided with flanges 321, which can increase the spatial mode of the connecting plate 32, thereby enhancing the bending and torsional stiffness of the connecting plate 32; it can also increase the contact area at the connection between the connecting plate 32 and the inner surface of the shell 1, thereby improving the connection strength between the connecting plate 32 and the shell 1, and then improving the connection reliability.

[0053] Optionally, combined Figure 5 and Figure 6 As shown, a mounting step 322 is correspondingly provided at the upper end of the connecting plate 32, and the edge of the upper light-emitting component 21 is limited by the mounting step 322. Such an arrangement allows the mounting step 322 to limit the edge of the upper light-emitting component 21, thereby preventing the risk of the upper light-emitting component 21 falling off the radiator 3, thereby improving the installation stability between the two.

[0054] Specifically, combined Figure 5 and Figure 6 As shown, the connecting plate 32 includes an inclined section 323 and a vertical section 324, the upper light-emitting member 21 is connected to the upper part of the inclined section 323, the inclined section 323 extends obliquely in the up and down directions along the width direction of the shell 1, and the distance between the spaced inclined sections 323 gradually decreases from top to bottom. The vertical section 324 is connected to the lower end of the inclined section 323, and the heat dissipation plate 31 is connected to the connection between the inclined section 323 and the vertical section 324.

[0055] That is to say, the inclined sections 323 on the spaced-apart connecting plates 32 extend obliquely from top to bottom toward one side close to each other. Such an arrangement will construct a tapered opening, which can converge and guide the heat radiated downward by the upper light-emitting component 21 toward the heat dissipation plate 31, thereby improving the heat dissipation efficiency of the radiator 3.

[0056] In addition, a stress concentration area is formed at the connection between the inclined section 323 and the vertical section 324 , and connecting the heat sink 31 there can effectively enhance the structural strength of the area, thereby improving the structural reliability of the radiator 3 .

[0057] Further, combined with Figure 1 、 Figure 3-Figure 6 As shown, the upper light-emitting element 21 is constructed in an elongated strip shape, and its vertical projection is located within the vertical projection of the heat sink 3. The elongated strip shape of the upper light-emitting element 21 effectively increases the illumination coverage of the upper light-emitting element 21 without occupying an excessively large width, while also achieving the effects of energy conservation and improved lighting efficiency.

[0058] In addition, the projection of the upper light-emitting component 21 in the up-down direction is located within the projection of the radiator 3 in the up-down direction, so that the radiator 3 can effectively cover the heat radiation range emitted by the upper light-emitting component 21 toward one side of the radiator 3, thereby ensuring the heat dissipation effect of the radiator 3.

[0059] Optionally, the heat sink 3 is an integrally formed metal structure.

[0060] That is to say, the radiator 3 adopts an integrated molding process, which can reduce the number of parts and assembly time, thereby reducing assembly processes, reducing manufacturing costs, and improving production efficiency; it can also avoid the matching errors that may occur in traditional multi-piece assembly, thereby improving product accuracy and consistency; it can also reduce stress concentration points (due to the absence of seams and welds), thereby improving the overall structural strength and rigidity of the structure, and thus improving the practicality of the radiator 3.

[0061] In addition, the radiator 3 is a metal structural component. Since metal has high structural strength and rigidity, such an arrangement can effectively improve the service life of the radiator 3.

[0062] According to some optional embodiments of the present invention, combined with Figures 1-8 As shown, the lower light-emitting component 22 is arranged on the bottom side of the shell 1, and the lower light-emitting component 22 extends along the circumference of the shell 1. The light-emitting component 2 also includes a light guide plate 23, and the light guide plate 23 is arranged opposite to the lower opening 12 up and down. The heat sink 3 is connected between the upper light-emitting component 21 and the light guide plate 23, and the lower light-emitting component 22 surrounds the outer circumference of the light guide plate 23 for emitting light downward from the circumference of the light guide plate 23.

[0063] Specifically, in the top and bottom directions, the housing 1 is provided with an upper opening 11 and a lower opening 12, respectively. The light emitted by the upper light-emitting element 21 can pass through the upper opening 11 and illuminate the top side of the housing 1, thereby achieving a top lighting effect; the light emitted by the lower light-emitting element 22 surrounding the outer periphery of the light guide plate 23 can be guided by the light guide plate 23 and pass through the lower opening 12 to illuminate the bottom of the housing 1, thereby achieving a bottom lighting effect. In summary, when the upper light-emitting element 21 and the lower light-emitting element 22 emit light at the same time, the upper light-emitting element 21 can enhance the brightness of the ambient light above the housing 1, and can also make the ambient light more uniform and soft, thereby reducing the effect of the ambient shadow cast by the lower light-emitting element 22 on the user when performing bottom lighting work, and can also have an anti-glare effect on the user, thereby improving the user's visual comfort.

[0064] Optionally, combined Figure 3-Figure 4 As shown, the light emitting assembly 2 further includes an optical processing portion 232 , which is disposed on the lower surface of the light guide plate 23 . The optical processing portion 232 is one of a prism plate and a PC board with a frosted layer.

[0065] Among them, since the optical processing part 232 is located on the lower surface of the light guide plate 23, the optical processing part 232 can further process the light passing through the light guide plate 23, thereby improving the guiding processing effect of the light emitting component 2 on the light irradiation direction and irradiation range.

[0066] Optionally, the optical processing unit 232 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 disposed on the lower surface of the light guide plate 23, it can be used to guide light emitted from the light guide plate 23 downward, thereby making the reflected light more concentrated and brighter, thereby effectively improving lighting efficiency.

[0067] Alternatively, the optical processing part 232 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 %) 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.

[0068] That is to say, by arranging the optical processing part 232 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 mirror 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.

[0069] In detail, combined Figure 4 As shown, the light-emitting assembly 2 further includes a diffusion film 24, which is disposed on at least one surface of the optical processing portion 232. The primary function of the diffusion film 24 is to scatter light. In this embodiment, the diffusion film 24 is disposed along the light transmission path. This allows for a more even distribution of light (the diffusion film 24, 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 light allows the light to better cover the entire lighting area, increasing light utilization), thereby effectively enhancing lighting quality and visual comfort.

[0070] Optionally, combined Figure 3-Figure 5 and Figure 9 As shown, the lighting lamp 100 also includes a diffuser plate 25, which is located above the upper light-emitting component 21, and the diffuser plate 25 and the upper light-emitting component 21 are arranged relative to each other up and down. The main function of the diffuser plate 25 is to scatter light, so that the distribution of light emitted by the upper light-emitting component 21 can be more uniform, thereby improving the lighting effect of the upper light-emitting component 21.

[0071] According to the second aspect of the present invention, the study table includes the lighting lamp 100 of the study table of the above embodiment. The study table with the lighting lamp 100 can improve the heat dissipation effect of the light-emitting component 2, thereby improving the working efficiency of the light-emitting component 2 and extending the service life of the device, thereby improving market competitiveness.
