Abstract
Description
Technical Field
[0001] This utility model relates to lighting fixtures, and more particularly to a polarized eye-protection lamp. Background Technology
[0002] Floor lamps are common lighting fixtures in home and office environments, used to provide localized lighting or to create an overall ambiance.
[0003] Floor lamps in related technologies typically have a relatively simple function. One type is direct lighting, where the light source shines downwards, primarily used for tasks such as reading and writing. However, this type of lamp has a limited illumination range and tends to create dark shadows outside the illuminated area, resulting in excessively strong contrasts between light and dark areas in the space. The other type is indirect lighting, where the light source shines upwards, providing soft, even ambient light through diffuse reflection from the ceiling or walls. However, the area directly beneath this type of lamp is often insufficiently bright, failing to meet the lighting needs for close-range work.
[0004] To accommodate both functions, floor lamps with both upward and downward light emission have appeared on the market. However, in these existing combined lighting fixtures, the upward-emitting LED panels are usually arranged horizontally. This limits the effective area and angle of upward light emission, making it difficult to create a wide-ranging and evenly distributed ambient light effect. At the same time, the downward-lighting portion often suffers from glare problems due to structural design limitations, affecting the user's visual comfort. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0068] The polarized eye-protection lamp of this utility model is described in detail below with reference to the accompanying drawings.
[0069] Reference Figures 1 to 5 As shown, the polarized eye-protection lamp provided according to the embodiment of this utility model includes a lamp housing 10, two upward-facing LED lamp panels 20, a light-transmitting plate 21, a downward-facing LED lamp panel 30, and a light guide plate 31.
[0070] Specifically, the lamp housing 10 can be made of a metal material with good thermal conductivity, such as aluminum alloy, or high-strength engineering plastics, to ensure structural stability and heat dissipation requirements.
[0071] Two upward-illuminated LED panels 20 are spaced apart along the width direction of the lamp housing 10. Each upward-illuminated LED panel 20 is inclined downward along the width direction of the lamp housing 10 from one end near the center of the lamp housing to one end away from the center of the lamp housing 10, so that the upward-illuminated LED panel 20 emits light upward at an angle.
[0072] From the cross-section of the lamp housing 10, the two upward-facing LED panels 20 together form an inverted trapezoid, with the two hypotenuses corresponding to the positions of the two upward-facing LED panels 20. This tilted design causes the light emitted by the LED light sources on the upward-facing LED panels 20 to no longer shine vertically upwards, but rather to shine obliquely upwards at a larger divergence angle, thereby greatly increasing the coverage angle of the upward-emitting light and the effective light-emitting area.
[0073] A light-transmitting plate 21 is disposed above the two uplight LED light panels 20 for emitting light from the two uplight LED light panels 20. The light-transmitting plate 21 can be a PC (polycarbonate) or PMMA (acrylic) sheet with high light transmittance, and its surface can be frosted or misted to further soften the light and protect the internal uplight LED light panels 20 from dust.
[0074] A downward-facing LED light panel 30 is disposed between the two upward-facing LED light panels 20 for emitting light downwards. A light guide plate 31 is disposed below the downward-facing LED light panel 30 for guiding the light emitted by the downward-facing LED light panel 30.
[0075] In other words, a downlighting LED panel 30 is positioned in the central area between two tilted uplighting LED panels 20. This downlighting LED panel 30 emits light downwards, aiming to provide concentrated, high-brightness illumination to the area directly below the luminaire. Simultaneously, a light guide plate 31 is positioned below the downlighting LED panel 30. The light guide plate 31 is typically made of optical-grade PMMA or similar materials. Utilizing its internal reflective properties and surface optical structures, such as printed or etched microstructure dots (like light guide points or microprisms), the light emitted from the downlighting LED panel 30 is uniformly converted into a surface light source across the entire panel before being directed outwards. Therefore, when the light emitted from the downlighting LED panel 30 enters the light guide plate 31, it undergoes internal conduction and microstructure scattering before exiting from the lower surface of the light guide plate 31 in a uniform and soft manner. This effectively reduces the glare of the light source, prevents eye strain, and provides comfortable and healthy lighting for users' close-range visual activities such as reading and writing.
[0076] According to the polarized eye-protection lamp provided in this embodiment of the present invention, on the one hand, by setting the two upward-illuminated LED light panels 20 to a structure that tilts downward from the center outward along the width direction of the lamp housing 10, the effective area and angle of upward light emission are significantly increased, thereby expanding the coverage of indirect lighting and making the ambient light formed by reflection from the ceiling wider and more uniform. On the other hand, the downward-illuminated LED light panel 30 set in the lamp housing 10, together with the light guide plate 31 below it, can not only provide sufficient lighting for the area directly below, but also make the emitted light uniform and soft through the light guide plate 31's light-uniforming and light-expanding effects, effectively reducing glare problems and greatly improving visual comfort when using light at close range.
[0077] Reference Figure 1 As shown in some embodiments of this utility model, the polarized eye-protection lamp further includes a base 40 and a lamp post 50, wherein the lamp post 50 is disposed on the base 40 and the lamp housing 10 is disposed at the upper end of the lamp post 50.
[0078] By adding a base 40 and a lamp post 50, this polarized eye-protection lamp can be transformed into a floor lamp. This form broadens the product's application scenarios, allowing it to be used not only on desks but also as a primary or secondary light source in living rooms, bedrooms, studies, or rest areas. Combining the broad, uniform ambient light created by upward-facing indirect lighting with the soft, glare-free focused light provided by the downward-facing light guide plate 31 not only meets the basic lighting needs of large spaces but also addresses the focused lighting requirements for close-range reading and relaxation. This improves light quality and visual comfort while optimizing the layout and aesthetics of the interior space, satisfying diverse usage needs across various scenarios.
[0079] Reference Figures 2 to 5 As shown, in some embodiments of this utility model, the lamp housing 10 includes a bottom housing 101 and a top housing 102. The top housing 102 is detachably disposed above the bottom housing 101, for example, the two are connected by clips, screws or other fasteners. The top surface of the top housing 102 has two upper lamp slots H10, which are spaced apart in the width direction of the top housing 102. The bottom surface of the top housing 102 has a lower lamp slot H11.
[0080] The lower light trough H11 is located between the two upper light troughs H10. Two upward-illuminated LED light panels 20 are respectively disposed within the two upper light troughs H10. Two light-transmitting plates 21 are respectively disposed at the light outlets of the two upper light troughs H10. A downward-illuminated LED light panel 30 is disposed within the lower light trough H11, and a light guide plate 31 is disposed at the light outlet of the lower light trough H11.
[0081] During assembly, the downlight LED panel 30 is first installed inside the lower lamp groove H11 on the bottom surface of the top shell 102, ensuring its stable centered position. Then, the light guide plate 31 is placed on the bottom shell 101, and the top shell 102 is fixed to the bottom shell 101, ensuring that the light outlet of the lower lamp groove H11 is aligned with the light guide plate 31. Next, the two uplight LED panels 20 are respectively accommodated and fixed within the two upper lamp grooves H10. Finally, the light-transmitting plate 21 is installed on the top shell 102, aligned with the light outlet of the upper lamp groove H10.
[0082] By designing the lamp housing 10 as a detachable structure consisting of a bottom housing 101 and a top housing 102, the production and assembly process is simplified, modular installation is achieved, and production efficiency is improved. This highly integrated design allows the upward-facing LED light panel 20 and the downward-facing LED light panel 30 to form independent, protected modules, facilitating subsequent maintenance.
[0083] Reference Figure 2 and Figure 5As shown, in one embodiment of this utility model, the upper lamp slot H10 includes a bottom wall B101 and two side walls B102. The bottom wall B101 is inclined downward along the width direction of the lamp housing 10 from one end near the center of the lamp housing to one end away from the center of the lamp housing 10. An upward-illuminated LED light panel 20 is disposed on the bottom wall B101, and the two side walls are respectively located on both sides of the bottom wall B101, forming a trapezoidal light outlet between them.
[0084] In other words, the bottom wall B101 of the upper lamp trough H10 is not horizontal, but rather slopes smoothly downwards at a predetermined angle along the width direction of the lamp housing 10, from one end near the central axis of the lamp body to the outer end away from the central axis. This integrally formed inclined structure provides an installation reference surface with a fixed tilt angle for the upward-illuminated LED light panel 20.
[0085] When the uplight LED panel 20 is placed and fixed on the inclined bottom wall B101, its light-emitting surface naturally forms an inclined posture, thereby ensuring that the emitted light can be emitted at an angle upwards. The two side walls B102 extend upwards from the edge of the bottom wall B101 at a certain angle to form the boundary of the upper lamp groove H10. The two side walls B102 together constitute and define the light outlet. Since the two side walls B102 are inclined, the light outlet formed between the two side walls B102 is trapezoidal. This trapezoidal light outlet ensures that the light emitted from the uplight LED panel 20 inside has a larger illumination angle, thereby covering a larger area, and also facilitates the installation and maintenance of the uplight LED panel 20.
[0086] Reference Figure 2 and Figure 5 As shown, in one embodiment of the present invention, a first connecting wall B103 is provided between one edge of the bottom wall B101 in the width direction and one of the two side walls B102, and a first slot H101 is provided on the first connecting wall B103. A second connecting wall B104 is provided between the other edge of the bottom wall B101 in the width direction and the other of the two side walls B102, and a second slot H102 is provided on the second connecting wall B104.
[0087] One side of the uplight LED light panel 20 is fitted into the first slot H101, and the other side of the uplight LED light panel 20 is fitted into the second slot H102.
[0088] During assembly, operators do not need to use any screws, glue, or other additional fasteners. They simply align the two side edges of the uplight LED light panel 20 with the first slot H101 and the second slot H102 respectively, and insert it along the length of the lamp housing 10 into the first slot H101 and the second slot H102. The light panel will then be securely installed in place. This snap-fit connection method ensures that the two long sides of the uplight LED light panel 20 are firmly fixed by the first slot H101 and the second slot H102. In this way, tool-free and rapid assembly of the uplight LED light panel 20 is achieved. Fixing can be completed through a simple plug-in action, which greatly simplifies the production process, significantly shortens assembly time, reduces labor costs, and facilitates maintenance.
[0089] Reference Figure 2 and Figure 5 As shown, in one embodiment of this utility model, a third slot H103 is provided on one side of the light outlet width direction of the upper lamp slot H10, and a fourth slot H104 is provided on the other side of the light outlet width direction of the upper lamp slot H10. One side of the light-transmitting plate 21 is engaged in the third slot H103, and the other side of the light-transmitting plate 21 is engaged in the fourth slot H104.
[0090] By using the third slot H103 and the fourth slot H104 on both sides of the light outlet to install the light-transmitting plate 21, tool-free and rapid assembly of the light-transmitting plate 21 is achieved, greatly simplifying the operation process on the production line, significantly improving production efficiency and reducing labor costs. In addition, this structure ensures that the light-transmitting plate 21 is stable and reliable on the lamp housing 10, and the overall structure is more concise and aesthetically pleasing.
[0091] Reference Figure 2 and Figure 5 As shown, in one embodiment of the present invention, the inner top surface of the lower lamp slot H11 is provided with a plurality of heat dissipation protrusions 1021, the plurality of heat dissipation protrusions 1021 are spaced apart along the width direction of the top shell 102, and each heat dissipation protrusion 1021 extends along the length direction of the top shell 102, and the downlight LED lamp board 30 is disposed on the plurality of heat dissipation protrusions 1021.
[0092] When the downlight LED panel 30 generates heat during operation, the heat can be quickly conducted from the downlight LED panel 30 to these heat dissipation protrusions 1021, and further diffused to the entire top shell 102 with a large heat capacity and surface area, and then dissipated into the surrounding environment. In this way, its heat dissipation effect is improved, ensuring the stability and reliability of light emission and extending its service life.
[0093] Reference Figures 2 to 4As shown, in one embodiment of the present invention, the bottom shell 101 has an illumination window H12, and the edge of the illumination window H12 has an inwardly protruding baffle portion 1011.
[0094] The lower light groove H11 has pressing surfaces S10 formed on both sides in the width direction. The light guide plate 31 is located at the lighting window H12 and stops above the edge portion 1011. The pressing surfaces S10 are pressed against the top surface of the light guide plate 31.
[0095] During assembly, the light guide plate 31 is placed inside the bottom shell 101, with its bottom edge positioned above the retaining edge 1011. Since the overall size of the light guide plate 31 is slightly larger than the opening formed by the retaining edge 1011, the light guide plate 31 is supported by the retaining edge 1011, preventing it from falling out of the lighting window H12. Subsequently, when the top shell 102 is combined with the bottom shell 101, the pressing surfaces S10 located on both sides of the lower lamp groove H11 of the top shell 102 in the width direction will contact the top surface of the light guide plate 31 as the top shell 102 is pressed down. After the top shell 102 and the bottom shell 101 are completely fixed by fasteners such as clips or screws, the pressing surfaces S10 will exert a uniform pressure on the light guide plate 31, firmly pressing the light guide plate 31 onto the lower retaining edge 1011, forming a stable structure.
[0096] This structure utilizes the lamp housing 10's own structure to position and clamp the light guide plate 31, making its installation simple and convenient. Furthermore, it ensures the light guide plate 31 can be reliably and permanently fixed in its position, improving product performance and reliability.
[0097] Preferably, the width of the light guide plate 31 is 2 to 6 times the width of the lower lamp trough H11. Setting the width of the light guide plate 31 between 2 and 6 times the width of the lower lamp trough H11 ensures sufficient light mixing and achieves highly uniform surface light source output, while also ensuring that the lamp has a reasonable size.
[0098] Preferably, the tilt angle of the uplight LED panel 20 is between 10° and 30°. This range of tilt angles ensures that the light is directed toward the ceiling at a sufficiently large divergence angle to create a large area of soft light spots to create uniform ambient light, while effectively preventing light from directly entering the field of vision, thus achieving a balance between expanding the coverage of indirect lighting and preventing glare.
