Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a lamp. Background Technology

[0002] In the field of indoor lighting, the luminous effect, functional versatility, and light softness of lamps directly affect the user experience and visual health. Currently, most lamps on the market either have only a single luminous surface with a fixed lighting mode, which cannot meet the lighting needs of different scenarios (such as reading, sleeping, and waking up); or although they have multiple luminous surfaces, there is a lack of reasonable structural division between the luminous surfaces, which not only makes the overall shape messy, but also often has the problem of direct connection of luminous surfaces and inability to control them independently. In other words, multiple luminous surfaces can only be turned on or off at the same time, and cannot be adjusted individually according to actual needs, resulting in extremely poor flexibility.

[0003] Meanwhile, existing lamps that pursue soft lighting mostly rely on the diffuse reflection design of the lampshade, but the light may still have the problem of local direct light, especially when used at night. Direct light can easily irritate the eyes and is difficult to achieve the ideal eye protection effect. As users' demand for healthy lighting and scenario-based lighting increases, the market urgently needs a lamp that can adapt to various modes such as eye protection, reading, and sleep through flexible combination of different light-emitting surfaces, and can also meet the needs of eye health and soft light. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a lamp, comprising a main body with three independently arranged light-emitting surfaces: a first light-emitting surface facing upwards, and second and third light-emitting surfaces both facing downwards. The second light-emitting surface has a gap in the middle, and the third light-emitting surface is disposed within the gap. The main body also has a ring-shaped bracket, which is located between the second and third light-emitting surfaces to separate them. The first light-emitting surface is independently disposed above the bracket. The three light-emitting surfaces can emit light individually or collaboratively, and can be configured with different applicable modes such as eye protection, reading, wake-up, and sleep modes. When the first light-emitting surface emits light, the light is diffused through the ceiling to avoid direct illumination, achieving a soft and eye-protecting effect. The ring-shaped bracket achieves a reasonable separation and layout of the multiple light-emitting surfaces through a simple structure.

[0005] The technical solution of this utility model is implemented as follows: A lamp includes a main body, which includes an upward-facing first light-emitting surface, a second light-emitting surface, and a third light-emitting surface, both of which face downwards. The second light-emitting surface has a gap in the middle, and the third light-emitting surface is disposed in the gap in the middle of the second light-emitting surface. The first, second, and third light-emitting surfaces are all independently disposed. The main body also includes a bracket, which is ring-shaped and disposed between the second and third light-emitting surfaces, separating them. The first light-emitting surface is independently disposed above the bracket.

[0006] The main body is divided into three sections by a single ring-shaped bracket, ensuring that each section has at least one luminous surface. These three luminous surfaces are independently configured and not directly connected. This independent configuration also means that the three luminous surfaces do not necessarily need to be turned on or off simultaneously; they can emit light individually or collaboratively. This allows for different applicable modes to be configured for each luminous surface, achieving different functions when used individually or in combination, such as eye protection, reading, wake-up, sleep, and full brightness modes. Since the first luminous surface faces upwards, its illumination relies on diffuse reflection from the ceiling to avoid direct light and achieve a soft, eye-friendly effect.

[0007] Preferably, a second light-emitting element and a third light-emitting element are respectively provided on both sides of the bracket. The second light-emitting element is located on the side of the bracket with the second light-emitting surface and faces the second light-emitting surface, while the third light-emitting element is located on the side of the bracket with the third light-emitting surface and faces the third light-emitting surface. The bracket also separates the two light-emitting elements, achieving an independent effect for each other.

[0008] Preferably, a second light guide plate is provided on the outer side of the bracket, and a third light guide plate is provided on the inner side of the bracket. The second light-emitting element faces the end of the second light guide plate, and the third light-emitting element faces the end of the third light guide plate. Both the second and third light-emitting surfaces emit light from the side. A second light-transmitting plate is provided below the second light guide plate, and a third light-transmitting plate is provided below the third light guide plate. The second and third light-emitting surfaces are formed on the lower surface of the second and third light-transmitting plates. A reflective layer is also provided above the second light guide plate. Since both the second and third light-emitting surfaces emit light from the side, they also avoid direct light and have an eye-protecting effect. The second light guide plate is located on the outer side of the bracket, and a reflective layer is also provided above it to reflect upward-escaping light back downward, thereby improving light efficiency.

[0009] Preferably, the third light guide plate and the third light emitter are located within the bracket and below the first light-emitting surface, with a gap between the first light-emitting surface and the third light guide plate. A heat sink is disposed outside the third light guide plate and the third light emitter, with the third light emitter positioned along the outer contour of the heat sink on the inner edge of the heat sink. The third light guide plate is located within the heat sink. The heat sink has several protrusions, with gaps between the protrusions and the third light guide plate. Since the top and sides of the third light emitter and the third light guide plate are blocked, with only the bottom exposed, heat dissipation is limited. In this solution, the heat dissipation effect of the internal third light-emitting component is improved by adding gaps to the heat sink and above it.

[0010] Preferably, the support has a base plate, a first circuit board on the base plate, a first light-emitting element on the first circuit board, and a first light-transmitting plate above the first light-emitting element. The first light-emitting surface is formed on the upper surface of the first light-transmitting plate. The first light-emitting elements are distributed circumferentially in the middle of the main body and close to the center of the main body. The first light-emitting elements are relatively concentrated because the light emitted from the top surface needs to be concentrated to make the diffuse reflection of the ceiling a strong reflection. This achieves both eye protection and a brighter effect. Even when only the first light-emitting surface is emitting light, it can still ensure a sufficiently bright lighting effect, preventing eye damage from dim light. Reading in dim light is more harmful to the eyes.

[0011] Preferably, the substrate is connected to a mounting base located above it. The mounting base is ring-shaped, and the first circuit board, the first light emitter, and the first light-transmitting plate are all located inside the mounting base. The first light-transmitting plate is mounted on the upper part of the mounting base.

[0012] Preferably, the outer diameter of the second luminous surface is larger than that of the first luminous surface, and the outer diameter of the first luminous surface is larger than that of the third luminous surface. Since the third luminous surface is independently located within the second luminous surface, its outer diameter is smaller than that of the second luminous surface. This allows for a larger outer diameter of the first luminous surface, which facilitates the placement of more first luminous elements and makes them more concentrated, resulting in a brighter lighting effect even after diffuse reflection from the ceiling.

[0013] Preferably, the main body includes a first light-emitting component, a second light-emitting component, and a third light-emitting component. A first light-emitting surface is formed on the first light-emitting component, a second light-emitting surface is formed on the second light-emitting component, and a third light-emitting surface is formed on the third light-emitting component. The first light-emitting component is disposed above the support, and the second and third light-emitting components are disposed on the support with the second light-emitting component located on the outside of the support and the third light-emitting component located on the inside of the support. The height of the first light-emitting component is raised by the support and is located above the second and third light-emitting components. An open outer space is formed between the first light-emitting component and the second light-emitting component, and an inner space is formed between the first light-emitting component, the support, and the third light-emitting component. The outer space and the inner space are configured for heat dissipation of the light-emitting components. An outer space is formed between the first and second light-emitting components. Since the first light-emitting surface faces upward, the first light-emitting element will be located in a lower position. The first light-emitting element is the main heat-generating element, and most of the heat it emits will enter the outer space. The heat from the second light-emitting component will also naturally enter the outer space. The convection of the two hot airs will cause the heat to dissipate into the outside air more quickly, thereby greatly improving the heat dissipation performance and extending the service life. However, since the third light-emitting component is blocked from the top and sides by the bracket and the first light-emitting component, heat dissipation can only be downward. The upward movement of hot air will also hinder the heat dissipation of the third light-emitting component, making it the most difficult to dissipate heat. However, in this solution, an inner space is formed between the first and third light-emitting components, allowing the third light-emitting component to dissipate heat upward. At the same time, the bracket is also made of a material with good heat dissipation performance, such as aluminum, which alleviates the heat dissipation problem of the third light-emitting component.

[0014] Preferably, a plurality of spaced pads are provided between the first light-emitting component and the bracket, with a flow opening formed between two adjacent pads. The flow opening is configured to connect the inner space and the outer space. The flow opening allows the heat dissipated by the third light-emitting component into the inner space to flow out of the outer space as hot air. At this time, the outer space has convection of three types of hot air, which further accelerates heat dissipation, thus enabling the third light-emitting component to obtain better heat dissipation performance.

[0015] Preferably, the main body is connected to a mounting column, which is conical in shape and has a diameter that gradually increases from bottom to top. The mounting column is configured so that its surface reflects the light emitted from the first luminous surface. The mounting column allows the luminaire to be mounted on the ceiling. Because the mounting column is conical, a portion of the light emitted from the first luminous surface will hit the surface of the mounting column and be reflected obliquely downwards, thereby improving the luminous efficiency. The effect is even better when the surface of the mounting column is made of metal or reflective material.

[0016] The design starting point, concept, and beneficial effects of this utility model, which adopts the above technical solution, are as follows: The main body is divided into three sections by a single ring-shaped bracket, ensuring that each section has at least one luminous surface. These three luminous surfaces are independently configured and not directly connected. This independent configuration also means that the three luminous surfaces do not necessarily need to be turned on or off simultaneously; they can emit light individually or collaboratively. This allows for different applicable modes to be configured for each luminous surface, achieving different functions when used individually or in combination, such as eye protection, reading, wake-up, sleep, and full brightness modes. Since the first luminous surface faces upwards, its illumination relies on diffuse reflection from the ceiling to avoid direct light and achieve a soft, eye-friendly effect.

[0017] An outer space is formed between the first and second light-emitting components. Since the first light-emitting surface faces upward, the first light-emitting element will be located in a lower position. The first light-emitting element is the main heat-generating element, and most of the heat it emits will enter the outer space. The heat from the second light-emitting component will also naturally enter the outer space. The convection of the two hot airs will cause the heat to dissipate into the outside air more quickly, thereby greatly improving the heat dissipation performance and extending the service life. However, since the third light-emitting component is blocked from the top and sides by the bracket and the first light-emitting component, heat dissipation can only be downward. The upward movement of hot air will also hinder the heat dissipation of the third light-emitting component, making it the most difficult to dissipate heat. However, in this solution, an inner space is formed between the first and third light-emitting components, allowing the third light-emitting component to dissipate heat upward. At the same time, the bracket is also made of a material with good heat dissipation performance, such as aluminum, which alleviates the heat dissipation problem of the third light-emitting component.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0022] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] The specific implementation of this utility model is as follows: like Figure 1-7As shown, this utility model provides a lamp, including a main body 1 and a mounting post 2. The mounting post 2 is connected to the main body 1 and protrudes upward from the main body 1. The mounting post 2 is used to connect to the ceiling, enabling the lamp to be installed on the ceiling. The main body 1 includes a first light-emitting component, a second light-emitting component, a third light-emitting component, and a bracket 3. The bracket 3 is annular. The second light-emitting component is disposed on the bracket 3 and located outside the bracket 3. The second light-emitting component is also annular and has a second light-emitting surface 22 formed on it. The second light-emitting surface 22 corresponds to the annular shape and has a gap in the middle. The third light-emitting component is disposed on the bracket 3 and located inside the bracket 3. The third light-emitting component is disc-shaped and has a third light-emitting surface 23 formed on it. The third light-emitting surface 23 is located in the gap in the middle of the second light-emitting surface 22. After the second and third light-emitting components are installed on the bracket 3, the three components together form a disc shape. The first light-emitting component is positioned above the bracket 3, making it higher than the second and third light-emitting components. The first light-emitting component has a first light-emitting surface 21, which faces upward, while the second and third light-emitting surfaces face downward. In this design, the first light-emitting surface 21, the second light-emitting surface 22, and the third light-emitting surface 23 are all independently set. The bracket 3 is located between the second light-emitting surface 22 and the third light-emitting surface 23, separating them. The first light-emitting surface 21 is independently set above the bracket 3. The first light-emitting component is disc-shaped, and the second light-emitting component, the bracket 3, and the second light-emitting component are all disc-shaped. The two discs are separated from each other, making the main body 1 a double-disc stacked structure.

[0024] In this design, the main body 1 is divided into three sections by a single ring-shaped bracket 3, ensuring that each section has at least one light-emitting surface. The three light-emitting surfaces are independently configured and not directly connected. This independent configuration also means that the three light-emitting surfaces do not necessarily have to be turned on or off simultaneously. They can emit light individually or in combination, thus enabling different applicable modes to be configured for the three light-emitting surfaces. Different functions can be achieved when the three light-emitting surfaces are used individually or in combination, such as different modes like eye protection, reading, wake-up, sleep, and full brightness. Since the first light-emitting surface 21 faces upward, when the first light-emitting surface 21 emits light, it needs to be illuminated by diffuse reflection from the ceiling to avoid direct light and achieve a soft and eye-protecting effect.

[0025] Specifically, such as Figure 3 , 4As shown, the first light-emitting component includes a substrate 5, a first circuit board 6, a first light-emitting element 7, a first light-transmitting plate 8, and a mounting base 9. The substrate 5 serves as the main support for the first light-emitting component and is mounted on a bracket 3. The first circuit board 6 is mounted on the substrate 5, and the first light-emitting element 7 is mounted on the first circuit board 6. The first light-transmitting plate 8 is located above the first light-emitting element 7, and a first light-emitting surface 21 is formed on the upper surface of the first light-transmitting plate 8. The mounting base 9 is connected above the substrate 5, and the mounting base 9 is annular and located on the outer contour of the substrate 5. The first circuit board 6, the first light-emitting element 7, the first light-transmitting plate 8, and the first light-transmitting plate 9 are all mounted on the substrate 5. A light-transmitting plate 8 is located inside the mounting base 9. The first light-transmitting plate 8 is disc-shaped and installed on the upper part of the mounting base 9. Several first light-emitting bodies 7 are distributed in a ring around the center of the main body 1 and close to the center of the main body 1. The first light-emitting bodies 7 are relatively concentrated because the light emission from the top surface needs to be concentrated in order to make the diffuse reflection of the ceiling a strong reflection. While achieving the eye protection effect, it also achieves a brighter effect. That is, when only the first light-emitting surface 21 emits light, it can also ensure a sufficiently bright lighting effect and prevent damage to the eyes due to dim light. Reading in dim light is more harmful to the eyes.

[0026] like Figure 5 , 7 As shown, the second light-emitting component includes a second light-emitting element 10, a second circuit board 11, a second light guide plate 12, a second light-transmitting plate 13, and a reflective layer 14. In the second light-emitting component, each component is annular. The second circuit board 11 is mounted on the support 3 along the outer contour of the support 3. Several second light-emitting elements 10 are arranged circumferentially on the second circuit board 11. The second light guide plate 12 is located outside the second light-emitting elements 10, with the ends of the second light-emitting elements 10 facing the second light guide plate 12. The second light-transmitting plate 13 is disposed on the second light guide plate 12. Below, the second light-emitting surface 22 is formed on the lower surface of the second light-transmitting plate 13, and the reflective layer 14 is disposed above the second light guide plate 12; the lower end of the bracket 3 extends outward with an outward protrusion 31, and the bracket 3 is also provided with a pressure ring 4, which is located above the second light-emitting component. The second light guide plate 12, the second light-transmitting plate 13 and the reflective layer 14 are installed between the pressure ring 4 and the outward protrusion 31; a mounting ring 15 is also provided on the outside of the second light guide plate 12, the second light-transmitting plate 13 and the reflective layer 14, and the three are disposed between the mounting ring 15 and the bracket 3.

[0027] like Figure 5 , 6As shown, the third light-emitting component includes a third light-emitting element 16, a third circuit board 17, a third light guide plate 18, a third light-transmitting plate 19, and a heat sink 20. The lower end of the bracket 3 extends inward with an inner protrusion 32. The third light-transmitting plate 19 is mounted on the inner protrusion 32. The third light-emitting surface 23 is formed on the lower surface of the third light-transmitting plate 19. The third light guide plate 18 is placed on the third light-transmitting plate 19. The heat sink 20 covers the third light guide plate 18. The third circuit board 17 and the third light-emitting element 16 are located inside the bracket 3. The outer contour of the heat sink 20 extends downward with a lower protrusion 201. The third circuit board 17 and the third light-emitting element 16 are mounted... The second light-emitting body 10 and the third light-emitting body 16 are mounted on the lower protrusion 201 of the heat sink 20 and are positioned facing the end of the third light guide plate 18. The bracket 3 also separates the second light-emitting body 10 and the third light-emitting body 16 to achieve the effect of mutual independence. The bracket 3 is made of aluminum. The light-emitting body is close to the bracket 3, which helps to conduct heat from the light-emitting body to the bracket 3 for heat dissipation. In addition, under this arrangement, the second light-emitting surface 22 and the third light-emitting surface 23 are both side-emitting, which also avoids direct light and has the effect of protecting the eyes. The second light guide plate 12 is located outside the bracket 3, and a reflective layer 14 is also provided above it so that the upward-escaping light is reflected back downward to improve the light efficiency.

[0028] The third light guide plate 18 and the third light emitter 16 are located inside the bracket 3 and below the first light-emitting surface 21. There is a gap between the first light-emitting surface 21 and the third light guide plate 18. The heat sink 20 is provided with several protrusions 202, and there is a gap between the protrusions 202 and the third light guide plate 18. Since the top and sides of the third light emitter 16 and the third light guide plate 18 are blocked, only the bottom is exposed, so heat dissipation is limited. In this solution, the heat dissipation effect of the third light-emitting component located inside is improved by increasing the gap above the heat sink 20. The heat sink 20 is also made of aluminum.

[0029] The outer diameter of the second luminous surface 22 is larger than the outer diameter of the first luminous surface 21, and the outer diameter of the first luminous surface 21 is larger than the outer diameter of the third luminous surface 23. Since the third luminous surface 23 is independently located within the second luminous surface 22, the outer diameter of the third luminous surface 23 is smaller than the outer diameter of the second luminous surface 22. This makes the outer diameter of the first luminous surface 21 larger, which is conducive to arranging more first luminous bodies 7 and making the first luminous bodies 7 more concentrated, so that it can still have a brighter lighting effect after being diffused by the ceiling.

[0030] like Figure 8-11As shown, the height of the first light-emitting component is raised by the bracket 3 and positioned above the second and third light-emitting components. An open outer space 24 is formed between the first and second light-emitting components, and an inner space 25 is formed between the first light-emitting component, the bracket 3, and the third light-emitting component. The outer space 24 and the inner space 25 are configured for heat dissipation of the light-emitting components. The outer space 24 is formed between the first and second light-emitting components. Since the first light-emitting surface 21 faces upward, the first light-emitting element 7 will be located in a lower position. The first light-emitting element 7 is the main heat-generating element, and most of the heat it emits will enter the outer space 24, while the heat from the second light-emitting component... It will also naturally enter the outer space 24, and the convection of the two hot air will cause the heat to dissipate into the outside air more quickly, thereby greatly improving the heat dissipation performance and extending the service life. However, since the third light-emitting component is blocked from the top and sides by the bracket 3 and the first light-emitting component, the heat dissipation can only be downward. The rising of hot air will also cause the heat dissipation of the third light-emitting component to be obstructed, so the third light-emitting component is the most difficult to dissipate heat. However, since there is an inner space 25 between the first light-emitting component and the third light-emitting component in this solution, the third light-emitting component can dissipate heat upward. At the same time, the bracket 3 is also made of a material with good heat dissipation performance, such as aluminum, which alleviates the heat dissipation problem of the third light-emitting component.

[0031] A plurality of spacers 26 are provided between the first light-emitting component and the bracket 3, and a flow port 27 is formed between two adjacent spacers 26. The flow port 27 is configured to connect the inner space 25 and the outer space 24. The spacers 26 are provided on the upper surface of the pressure ring 4. The flow port 27 allows the heat dissipated by the third light-emitting component into the inner space 25 to flow out of the outer space 24 as hot air. At this time, the outer space 24 has convection of three kinds of hot air, which further accelerates the heat dissipation, and also enables the third light-emitting component to obtain better heat dissipation performance.

[0032] Furthermore, the mounting post 2 is a hollow cone-shaped cylinder with its diameter gradually increasing from bottom to top. The mounting post 2 is configured to reflect the light emitted from the first light-emitting surface 21. The mounting post 2 allows the luminaire to be installed on the ceiling. Because the mounting post 2 is cone-shaped, a portion of the light emitted upward from the first light-emitting surface 21 will hit the surface of the mounting post 2 and be reflected obliquely downward by the mounting post 2, thereby improving the light efficiency. The effect is even better when the surface of the mounting post 2 is made of metal or reflective material. At the same time, the mounting post 2 contains wiring, power supply, and control system. The mounting post 2 can provide independent heat dissipation for the wiring, power supply, control system, and even transformer, making the heat dissipation efficiency higher. The cone-shaped mounting post 2 is conducive to further reflecting the light from the first light-emitting surface 21. The effect is even better when the surface of the mounting post 2 is made of metal or reflective material.
