Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to an eye protection lamp. Background Art

[0002] As a lighting appliance, lamps make an important contribution to indoor lighting, especially study lamps, which can create a good indoor light environment for learning. However, with the progress of society, people have put forward higher requirements for lighting.

[0003] In order to save energy, the existing lamps on the market use LED lamps (i.e., lamp beads) for lighting. Currently, the closest prior art to this application is an eye protection lamp (publication number CN218936159U), whose light source is processed by a soft light plate to make it softer, which can improve the glare and dazzling problems to a certain extent. However, it is not ideal, and it still has the following shortcomings:

[0004] First, the light source generated by the light-emitting module in the lampshade is full-light direct irradiation, the light is strong, the light uniformity is insufficient, the visual comfort is poor, and the burden on the eyes is increased;

[0005] Second, the strong blue light and high color temperature generated by the light-emitting module lamp beads, while too much blue light may damage the retina, and high color temperature light may cause technical problems such as visual fatigue;

[0006] Third, the lamp beads of its light-emitting module are distributed on the mounting base, there is no heat sink, and the heat dissipation space is small, which affects the service life. Utility Model Content

[0007] The utility model provides an eye protection lamp to solve one or more problems raised in the above background technology.

[0008] In order to achieve the above-mentioned purpose, the scheme of the utility model is: an eye protection lamp, comprising a top plate, a lampshade, a light-emitting component and a light-transmitting component; the lampshade is arranged on the top plate; the light-emitting component is arranged in the top plate; it is characterized in that: the light-emitting component comprises a diffuse reflection cover, a ring seat and lamp beads, the ring seat is located in the diffuse reflection cover, the lamp beads are arranged on the outer side wall of the ring seat and distributed along the circumferential direction, and the inner wall of the ring seat is circumferentially provided with a heat sink; the light-transmitting component is arranged on the lampshade and corresponds to the position of the diffuse reflection cover; the light-transmitting component comprises a blue light filter and a color temperature sheet.

[0009] When the technical solution is working, the lamp beads on the circumferential distribution of the side wall of the ring seat generate radial side light that first shines on the diffuse reflection cover, then diffusely reflects through the diffuse reflection cover and then emits after being compositely processed by the blue light filter and the color temperature film. Since the inner surface of the diffuse reflection cover is a rough surface, when the light of the lamp beads shines on the rough surface, due to the uneven surface, although the incident light is parallel to each other, the normal direction of each point is inconsistent, resulting in the reflected light being irregularly reflected in different directions. The effect of diffuse reflection makes the light scattered in all directions instead of concentrating in a specific direction. Therefore, it can make the light shining on the surface of the object look more uniform and soft, and at the same time the light intensity is dispersed, weakened, and not dazzling. Therefore, through diffuse reflection, the light is softened and weakened, the light is scattered evenly, the visual comfort is better, and the burden on the eyes can be reduced. The diffusely reflected light is then processed by the blue light filter and the color temperature film to obtain low blue light, soft and low color temperature light, avoiding light glare or glare. In addition, since heat sinks are provided circumferentially on the inner wall of the ring seat, when the lamp beads on the outer wall of the ring seat generate heat circumferentially, the heat is dissipated circumferentially through the circumferentially distributed heat sinks. The heat dissipation space inside the ring seat is large and the heat is dissipated circumferentially through the circumferential heat sinks, which has good heat dissipation effect, can quickly cool down, can extend the service life of the lamp beads and is safe at work.

[0010] Therefore, this technical solution adopts side-lighting and realizes lighting after diffuse reflection, blue light filtering and soft light processing. It has the advantages of soft light, weak blue light, low color temperature, no glare, no dazzling, etc., which can effectively protect the eyes. At the same time, it has good heat dissipation performance, large heat dissipation space and long product service life.

[0011] The technical solution can solve the technical problems that the light module in the existing lampshade generates a planned light source that is direct full light, has strong light, insufficient light uniformity, poor visual comfort, and increased eye burden.

[0012] This technical solution can solve the technical problems that the existing light-emitting module lamp beads produce strong blue light and high color temperature, while excessive blue light may damage the retina and high color temperature light may cause visual fatigue.

[0013] This technical solution can solve the technical problem that the lamp beads of the existing light-emitting module are distributed on the mounting base, there is no heat sink, and the heat dissipation space is small, which affects the service life.

[0014] Furthermore, a heat dissipation hole is provided on the lampshade; the heat dissipation hole is located below the heat sink.

[0015] Furthermore, a plurality of circumferentially distributed elastic sheets are provided in the top plate; each of the elastic sheets is inserted into the ring seat and radially pressed against; and each of the elastic sheets has a protrusion at the lower end for limiting the downward displacement of the ring seat.

[0016] Furthermore, the lampshade is provided with an annular groove; the light-transmitting component is fixedly installed in the annular groove; a limiting ring is provided in the lampshade; the lower end of the diffuse reflection cover is inserted into the limiting ring and is concentrically positioned.

[0017] Furthermore, the lamp beads are LED lamp beads; a power adapter is installed in the top plate; and the power adapter is electrically connected to the lamp beads.

[0018] Furthermore, the diffuse reflection cover is conical.

[0019] Furthermore, the lamp beads are evenly distributed along the circumferential direction.

[0020] Furthermore, there are four elastic sheets.

[0021] Beneficial effects of the utility model:

[0022] First, the utility model is different from the existing structural design. It adopts side light emission and realizes lighting after diffuse reflection, blue light filtering and soft light processing. It has the advantages of soft light, weak blue light, low color temperature, no glare, no dazzling, etc., which can effectively protect the eyes. At the same time, it has good heat dissipation performance, large heat dissipation space and long product service life;

[0023] Second, since the utility model has heat sinks arranged circumferentially on the inner wall of the ring seat, the heat dissipation space in the ring seat is large and the heat is dissipated circumferentially through the circumferential heat sinks, which has good heat dissipation effect, can quickly cool down, can extend the service life of the lamp beads and is safe to work;

[0024] Third, the utility model has heat dissipation holes on the lampshade; the heat dissipation holes are located below the heat sink, so the heat on the heat sink can be discharged through the heat dissipation holes below, and at the same time, the external cold air enters the lampshade through the heat dissipation holes and contacts the heat sink for heat exchange, which can quickly discharge heat to the outside and exchange heat with cold air, which can greatly improve the heat dissipation performance and cooling effect;

[0025] Fourth, the utility model is fixed in the top plate by the elastic sheets in the ring seat, and the elastic sheets can be deformed under the action of external force. When the product is assembled, the ring seat is pressed upward and stuck on the elastic sheets, and the ring seat will not fall off, which can realize rapid assembly, good processability, and improve production efficiency. When the lamp bead is defective after use, the elastic sheets can be pressed radially inward first, and then the protrusions will deform and no longer block the ring seat, and then the ring seat can be pulled out downward to be removed, which is very convenient for disassembly and replacement.

[0032] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0033] Example 1: See Figure 1-5 An eye protection lamp comprises a top plate 1, a lampshade 2, a light-emitting component 3 and a light-transmitting component 4; the lampshade 2 is arranged on the top plate 1; and the light-emitting component 3 is arranged in the top plate 1.

[0034] See also Figure 1-2 The top plate 1 is provided with a plurality of mounting holes 1 - 2 , and the mounting holes 1 - 2 can be fixed to the floor 7 or the wall by screws 6 during installation.

[0035] See also Figure 1-2 Specifically, the light emitting assembly 3 includes a diffuse reflection cover 3-1, a ring seat 3-2 and a plurality of lamp beads 3-3, wherein the ring seat 3-2 is located in the diffuse reflection cover 3-1, each of the lamp beads 3-3 is arranged on the outer wall of the ring seat 3-2 and is evenly distributed along the circumference, and the inner wall of the ring seat 3-2 is provided with a heat sink 3-21 (see Figure 7 ).

[0036] See also Figure 1-2 Specifically, the diffuse reflection cover 3-1 is conical, and preferably has a taper of 45°.

[0037] See also Figure 1-2 Specifically, the light-transmitting component 4 is arranged on the lampshade 2 and corresponds to the position of the diffuse reflection cover 3-1; the light-transmitting component 4 is located below the diffuse reflection cover 3-1. The light-transmitting component 4 includes a blue light filter 4-1 and a color temperature sheet 4-2. Specifically, the blue light filter 4-1 and the color temperature sheet 4-2 are composited together in upper and lower layers.

[0038] The blue light filter 4-1 is used for filtering blue light of the light. The color temperature film 4-2 is used for making the color temperature of the light below 4000K (preferably, the color temperature of the light after being processed by the color temperature film 4-2 is in the optimal range of 2500K-3500K).

[0039] See also Figure 1-2 Further, the lampshade 2 is provided with an annular groove 2-2; the light-transmitting component 4 is fixedly installed in the annular groove 2-2; a limiting ring 2-3 is provided in the lampshade 2; the lower end of the diffuse reflection cover 3-1 is inserted into the limiting ring 2-3 and is concentrically positioned. The diffuse reflection cover 3-1 is positioned and assembled to ensure the stability of performance during operation.

[0040] Specifically, the light-transmitting component 4 is annular and can be fixed in the annular groove 2-2 by means of snap connection, embedding, or bonding.

[0041] See also Figure 1-2 When working, the lamp beads 3-3 distributed circumferentially on the side wall of the ring seat 3-2 generate radial side light, which first irradiates the diffuse reflection cover 3-1, then is diffusely reflected by the diffuse reflection cover 3-1, and then is emitted after being compositely processed by the blue light filter 4-1 and the color temperature film 4-2.

[0042] Since the inner surface of the diffuse reflection cover 3-1 is a rough surface, when the light of the lamp bead 3-3 is irradiated on the rough surface, due to the uneven surface, the incident light rays are parallel to each other, but the normal directions of each point are inconsistent, causing the reflected light rays to be irregularly reflected in different directions. The diffuse reflection effect makes the light scatter in all directions instead of concentrating in a specific direction. Therefore, it can make the light irradiated on the surface of the object look more uniform and soft, and at the same time, the light intensity is dispersed and weakened, and it will not be dazzling. Therefore, through diffuse reflection, the light is softened and weakened, the light is scattered evenly, the visual comfort is better, and the burden on the eyes can be reduced.

[0043] The diffusely reflected light is then processed by the blue light filter 4-1 and the color temperature film 4-2 to obtain low blue light, a color temperature not exceeding 4000K, and a softer light, which avoids glare or glare, reduces visual fatigue, provides a comfortable visual environment, and avoids visual fatigue caused by using high color temperature lights.

[0044] In addition, see Figure 7 Since heat sinks 3-21 are provided circumferentially on the inner wall of the ring seat 3-2, when the lamp beads 3-3 on the outer wall of the ring seat 3-2 generate heat circumferentially, the heat is dissipated circumferentially through the circumferentially distributed heat sinks 3-21. The heat dissipation space inside the ring seat 3-2 is large and heat is dissipated through the circumferential heat sinks 3-21, which has good heat dissipation effect, can quickly cool down, can extend the service life of the lamp beads 3-3 and is safe at work.

[0045] The present embodiment is different from the existing structural design. It adopts side-lighting and realizes lighting through diffuse reflection, blue light filtering and soft light processing. It has the advantages of soft light, weak blue light, low color temperature, no glare, no dazzling, etc., which can effectively protect the eyes. At the same time, it has good heat dissipation performance, large heat dissipation space and long product service life.

[0046] Specifically, see Figure 7 The heat sink 3-21 on the inner wall of the ring seat 3-2 is arranged at equal intervals to enhance the heat dissipation effect. The material is preferably aluminum alloy, which has the advantages of strong thermal conductivity and light weight.

[0047] Preferably, the heat sink 3-21 has a thickness of 0.5-1 mm, which is very light and low in cost.

[0048] See also Figure 1-2 Furthermore, the lampshade 2 is provided with a heat dissipation hole 2-1; the heat dissipation hole 2-1 is located below the heat sink 3-21. The heat on the heat sink 3-21 can be discharged through the heat dissipation hole 2-1 below, and at the same time, the external cold air enters the lampshade 2 through the heat dissipation hole 2-1 and contacts with the heat sink 3-21 for heat exchange, which can quickly discharge heat and exchange heat with cold air, greatly improving the heat dissipation performance and cooling effect.

[0049] See also Figure 1-2 Furthermore, the lamp bead 3-3 is an LED lamp bead; a power adapter 5 is fixedly installed in the top plate 1; and the power adapter 5 is electrically connected to the lamp bead 3-3.

[0050] Embodiment 2: This embodiment is basically the same as Embodiment 1, except that:

[0051] See also Figure 6 , a plurality of circumferentially distributed elastic sheets 1-1 are provided in the top plate 1; each of the elastic sheets 1-1 is inserted into the ring seat 3-2 and is radially pressed (see Figure 1-2 ); the lower end of each elastic sheet 1-1 has a protrusion 1-11 for limiting the downward displacement of the ring seat 3-2.

[0052] Specifically, the top plate 1 is made of plastic material, and the elastic sheet 1 - 1 has a thickness of 0.5-1 mm. Due to its thin thickness, it can be elastically deformed under the action of external force.

[0053] In this embodiment, see Figure 6 , the elastic sheets 1-1 have four.

[0054] Therefore, see Figure 1-2 , the ring seat 3-2 is clamped in the top plate 1 through each elastic sheet 1-1. Each elastic sheet 1-1 can be deformed under the action of external force. When assembling the product, the ring seat 3-2 is pressed upward and clamped on each elastic sheet 1-1. The ring seat 3-2 will not fall off, and can be quickly assembled. The process is good and the production efficiency can be improved. When the lamp bead is defective after use, the elastic sheets 1-1 can be pressed radially inward first, and then the protrusion 1-11 thereof is deformed and no longer blocks the ring seat 3-2. Then the ring seat 3-2 can be pulled out downward and removed, and disassembly and replacement are very convenient.

[0055] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
