Description

Technical Field

[0001] The present disclosure relates to the technical field of lighting, and in particular to a polarized table lamp and a lighting device. Background Art

[0002] Table lamps are usually used in offices, study rooms and other places. There are also table lamps using LEDs on the market to ensure their lighting effects. However, in current LED table lamps, the light from the light source directly irradiates the working surface.

[0003] Therefore, different enterprises have made different solutions for adjusting the lighting angle. For example, the existing patent CN102997105A discloses an LED table lamp, in which the lighting part is connected to the support part through the first hinge part, so that the lighting part rotates vertically with the first hinge part as the rotation center, and the support part is connected to the bracket through the second hinge part, so that the support part rotates vertically with the second hinge part as the rotation center to adjust the vertical irradiation angle.

[0004] However, the lighting range of this table lamp, that is, the lighting angle is very limited. When an object is too close to the light-emitting part of the table lamp, the table lamp cannot normally illuminate the designated position due to the object blocking the irradiated part, making the lighting range of the table lamp smaller. Therefore, when using the table lamp, the user cannot guarantee the lighting experience of the table lamp. Summary of the Utility Model

[0005] The purpose of the present disclosure is to overcome the deficiencies in the prior art and provide a polarized table lamp and a lighting device with a wider lighting range and better polarized lighting performance.

[0006] The purpose of the present disclosure is achieved by the following technical solutions:

[0007] A polarized table lamp includes a control panel, a support rod and a lighting component. The control end of the control panel is electrically connected to the power connection end of the lighting component. The support rod is installed on the control panel, and the lighting component is rotatably connected to the support rod. The lighting component includes:

[0008] A housing main body, and the housing main body is provided with a receiving groove;

[0009] The lighting component is connected to the inner wall of the receiving groove and includes a lighting housing, a light source component, and a polarizing component. The light source component and the polarizing component are both located inside the lighting housing. The lighting housing is connected to the housing body. The light-emitting part of the light source component is arranged towards the opening of the receiving groove through the polarizing component. The polarizing component includes a plurality of polarizing units. Each polarizing unit has a first lighting wall, a second lighting wall, a polarizing wall, and a third lighting wall. The extension line of the first lighting wall and the extension line of the second lighting wall form a lighting angle of the lamp. The extension line of the polarizing wall and the extension line of the third lighting wall form a polarized lighting angle, so that the light emitted by the light source component passes through the polarizing component and exits under the guidance of the lighting angle of the lamp and the polarized lighting angle.

[0010] In one embodiment, the range of the lighting angle of the lamp is 80° to 85°.

[0011] In one embodiment, the range of the polarized lighting angle is 100° to 110°.

[0012] In one embodiment, the lighting component further includes a rotating member. The rotating member is connected to the lighting housing. The rotating member protrudes with a first rotating column. One end of the lighting housing away from the rotating member protrudes with a second rotating column. The housing body is provided with a first connection hole and a second connection hole. The first rotating column passes through the first connection hole, and the second rotating column passes through the second connection hole, so that the lighting housing is rotationally connected to the housing body with the rotation axis formed by the first rotating column and the second rotating column, and when the lighting housing rotates clockwise or counterclockwise around the rotation axis to a certain angle, it abuts against the inner wall of the housing body.

[0013] In one embodiment, the polarized table lamp further includes a rotating joint. The rotating joint is installed inside the support rod. The housing body is connected to the support rod through the rotating joint, so that the housing body is vertically rotationally connected to the support rod with the rotating joint as the center.

[0014] In one embodiment, the range of the vertical rotation angle formed by the housing body and the support rod is 0° to 90°.

[0015] In one embodiment, the support rod includes a lamp rod housing, a light-transmitting sheet, and an auxiliary light source. One end of the lamp rod housing is connected to the control panel. The other end of the lamp rod housing is rotationally connected to the housing body. The light-transmitting sheet and the auxiliary light source are both located inside the lamp rod housing. The lamp rod housing has an ambient lighting area. A plurality of light-emitting holes are provided in the ambient lighting area. The light-transmitting sheet also covers the light-emitting holes. The light-emitting end of the auxiliary light source faces the light-transmitting sheet.

[0016] In one embodiment, the light-emitting aperture is hexagonal in shape.

[0017] In one embodiment, the control panel is provided with a rotating circular groove, and the polarized table lamp further includes a rotating circular platform. The rotating circular platform is located in the rotating circular groove, and one end of the lamp pole housing away from the housing main body is connected to the rotating circular platform, so that the support rod is rotatably connected to the control panel with the rotating circular platform as the center.

[0018] An illumination device includes the polarized table lamp according to any one of the above embodiments.

[0019] Compared with the prior art, the present disclosure includes but is not limited to the following advantages:

[0020] 1. For the above-mentioned polarized table lamp, polarized lighting is performed by using a polarizing member. The settings of the first lighting wall, the second lighting wall, the polarizing wall, and the third lighting wall enable the light irradiated by the light source member to exit through the polarizing member at the lighting angle of the lamp formed by the extension line of the first lighting wall and the extension line of the second lighting wall and the polarized lighting angle formed by the extension line of the polarizing wall and the extension line of the third lighting wall. This makes the lighting range of the table lamp relatively wide. Even if an object is relatively close to the light-emitting part of the table lamp, some light is still reflected out through the polarizing wall of any polarizing unit, so that the polarized lighting performance is relatively good, and the lighting experience of the table lamp can be guaranteed. Among them, under the action of the polarizing wall, the polarized lighting angle is relatively large, and unidirectional extended polarized lighting can be achieved.

[0021] 2. The rotating member adjusts the polarized lighting position of the light source member by horizontally rotating the lighting housing by adjusting the rotation angle, so that on the basis of the light being guided out at the lighting angle of the lamp, a wider lighting range can be achieved.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present disclosure belongs. The terms used in the specification of the present disclosure herein are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] To better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail with reference to specific embodiments as follows:

[0039] Please refer to Figures 1 to 3 , which is a polarized table lamp 10 according to an embodiment of the present utility model, including a control panel 100, a support rod 200 and a lighting assembly 300.

[0040] The control end of the control panel 100 is electrically connected to the power connection end of the lighting assembly 300. The support rod 200 is installed on the control panel 100, and the lighting assembly 300 is rotatably connected to the support rod 200.

[0041] Combined with Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, the lighting assembly 300 includes a housing body 310 and a lighting component 320. The housing body 310 is provided with a receiving groove 3101. The lighting component 320 is connected to the inner wall of the receiving groove 3101. The lighting component 320 includes a lighting housing 321, a light source component 322, and a polarizing component 323. Both the light source component 322 and the polarizing component 323 are located within the lighting housing 321. The light-emitting portion of the light source component 322 is arranged to face the opening of the receiving groove 3101 through the polarizing component 323. The polarizing component 323 includes a plurality of polarizing units. Each polarizing unit has a first lighting wall 3231, a second lighting wall 3232, a polarizing wall 3233, and a third lighting wall 3234. The extension line of the first lighting wall 3231 and the extension line of the second lighting wall 3232 form a lighting angle of the lamp projected onto the X-axis. The extension line of the polarizing wall 3233 and the extension line of the third lighting wall 3234 form a polarized lighting angle projected onto the Y-axis, so that the light emitted by the light source component 322 passes through the polarizing component 323 and exits under the guidance of the lighting angle of the lamp and the polarized lighting angle. The effect diagram is as Figure 5 and Figure 7 shown.

[0042] It can be understood that the first lighting wall 3231 and the second lighting wall 3232 are arranged face to face, and the polarizing wall 3233 and the third lighting wall 3234 are arranged face to face, so that the extension line of the first lighting wall 3231 and the extension line of the second lighting wall 3232 form a lighting angle of the lamp and are projected onto the X-axis, and the extension line of the polarizing wall 3233 and the extension line of the third lighting wall 3234 form a polarized lighting angle and are projected onto the Y-axis, further enabling the light to form area lighting with the length of the projection of the lighting angle of the lamp onto the plane and the width of the projection of the polarized lighting angle onto the plane.

[0043] In this embodiment, the polarized table lamp 10 uses the polarizing component 323 for polarized lighting. The settings of the first lighting wall 3231, the second lighting wall 3232, the polarizing wall 3233, and the third lighting wall 3234 enable the light irradiated by the light source component 322 to exit through the polarizing component 323 at the lighting angle of the lamp formed by the extension line of the first lighting wall 3231 and the extension line of the second lighting wall 3232 and the polarized lighting angle formed by the extension line of the polarizing wall 3233 and the extension line of the third lighting wall 3234. As a result, the lighting range of the table lamp is relatively wide. Even if an object is relatively close to the light-emitting part of the table lamp, some light is still reflected and exits through the polarizing wall 3233 of any polarizing unit, so that the polarized lighting performance is relatively good and can ensure the lighting experience of the table lamp. Among them, under the action of the polarizing wall 3233, the polarized lighting angle is relatively large, and unidirectional extended polarized lighting can be achieved.

[0044] Furthermore, the range of the lighting angle of the lamp is 80° to 85°. In this embodiment, the lighting angle of the lamp is 80°.

[0045] Further, the range of the polarized illumination angle is 100° to 110°. In this embodiment, the polarized illumination angle is 100° to obtain a wider illumination range and achieve extended polarized illumination. Further, the polarization angle α formed by the extension line of the polarization wall 3233 and the extension line perpendicular to the illumination housing 321 (i.e., the normal line γ) is greater than the general illumination angle β formed by the extension line of the polarization wall 3233 and the normal line γ. Further still, the polarization angle α is 70° and the general illumination angle β is 30°. The effect diagram is as Figure 11 shown.

[0046] As Figure 6 , Figure 8 and Figure 9 shown, in one embodiment, the illumination component 320 further includes a rotating member 324. The rotating member 324 is connected to the illumination housing 321. The rotating member 324 protrudes with a first rotating column 3241. One end of the illumination housing 321 away from the rotating member 324 protrudes with a second rotating column 3211. The housing main body 310 is provided with a first connection hole 311 and a second connection hole 312. The first rotating column 3241 passes through the first connection hole 311, and the second rotating column 3211 passes through the second connection hole 312, so that the illumination housing 321 is rotatably connected to the housing main body 310 with the rotation axis formed by the first rotating column 3241 and the second rotating column 3211, and when the illumination housing 321 rotates clockwise or counterclockwise around the rotation axis to a certain angle, it abuts against the inner wall of the housing main body 310, thereby preventing the illumination housing 321 from rotating infinitely and further preventing the cable connected to the light source member 322 from knotting due to the infinite rotation of the illumination housing 321. It can be understood that starting from the plane where the polarizing member 323 is vertically oriented, when the rotation axis formed by the first rotating column 3241 and the second rotating column 3211 rotates clockwise by a certain angle, one side of the illumination housing 321 abuts against the inner wall of the housing main body 310; when the rotation axis rotates counterclockwise by a certain angle, the other side of the illumination housing 321 abuts against the inner wall of the housing main body 310. In this embodiment, starting from the plane where the polarizing member 323 is vertically oriented, the angle of rotation of this starting point until the illumination housing 321 abuts against the inner wall of the housing main body 310 is 20°. Thus, on the basis of the illumination within the illumination angle range of the light irradiated by the light source member 322, the illumination housing 321 is driven by the rotating member 324 to rotate and adjust to obtain a wider illumination range.

[0047] As Figure 4 and Figure 6As shown, in one embodiment, the polarized table lamp 10 further includes a rotating joint 400. The rotating joint 400 is installed inside the support rod 200. The housing main body 310 is connected to the support rod 200 through the rotating joint 400, so that the housing main body 310 is rotatably connected to the support rod 200 with the rotating joint 400 as the center. It can be understood that the support rod 200 is installed on the control panel 100 as a fixed component, while the housing main body 310 is connected to the support rod 200 through the rotating joint 400, enabling the housing main body 310 to rotate vertically with the rotating joint 400 as the center, that is, the housing main body 310 is an active component. In addition, the rotating joint 400 is installed inside the support rod 200, which can reduce the entry of external dust or moisture into the rotating joint 400 and ensure the normal rotation of the housing main body 310.

[0048] In one embodiment, the angle range formed by the housing main body 310 and the support rod 200 is 0° to 90°. It can be understood that when the housing main body 310 forms any angle from 1° to 90° with the support rod 200, the illumination position of the light emitted by the light source member 322 can be adjusted vertically; when the lighting assembly 300 is no longer powered on for illumination, by rotating the housing main body 310 to form a 0° angle with the support rod 200, that is, the housing main body 310 and the support rod 200 are closed, so as to reduce the overall space of the table lamp.

[0049] As Figure 3 、 Figure 4 and Figure 6 As shown, in one embodiment, the support rod 200 includes a lamp rod housing 210, a light-transmitting sheet 220 and an auxiliary light source 230. One end of the lamp rod housing 210 is connected to the control panel 100, and the other end of the lamp rod housing 210 is rotatably connected to the housing main body 310. The light-transmitting sheet 220 and the auxiliary light source 230 are both located inside the lamp rod housing 210. The lamp rod housing 210 has an ambient lighting area, and a plurality of light-emitting holes 2101 are formed in the ambient lighting area. The light-transmitting sheet 220 also covers the light-emitting holes 2101; the light-emitting end of the auxiliary light source 230 faces the light-transmitting sheet 220. It can be understood that the auxiliary light source 230 is installed inside the lamp rod housing 210. When the auxiliary light source 230 illuminates, the light passes through the light-transmitting sheet 220 and exits from the light-emitting holes 2101, playing the role of ambient lighting. Since the light-transmitting sheet 220 covers a plurality of light-emitting holes 2101, it prevents external dust or moisture from entering the lamp rod housing 210, further avoiding the situation that the illumination performance of the auxiliary light source 230 is affected by dust accumulation.

[0050] In this embodiment, the light-emitting holes 2101 are hexagonal in shape. It can be understood that the hexagonal light-emitting holes 2101 are arranged compactly, with lower material costs and the largest available space, which can ensure the effect of ambient lighting when the auxiliary light source 230 illuminates.

[0051] AsFigure 1 and Figure 2 As shown in Figure 2 , in one of the embodiments, the control panel 100 is provided with a rotating circular groove 101, and the polarized table lamp 10 further includes a rotating circular platform 500. The rotating circular platform 500 is located in the rotating circular groove 101. One end of the lamp pole housing 210 away from the housing main body 310 is connected to the rotating circular platform 500, so that the support rod 200 is rotatably connected to the control panel 100 with the rotating circular platform 500 as the center. It can be understood that when it is necessary to horizontally rotate the lighting assembly 300, by rotating the circular platform 500, the support rod 200 follows the circular platform 500 and rotates in the rotating circular groove 101, thereby horizontally adjusting the angle of the lighting assembly 300, so that the light source member 322 can obtain a wider horizontal lighting range.

[0052] The present disclosure also provides a lighting device, including the polarized table lamp 10 according to any one of the above embodiments.

[0053] Compared with the prior art, the present disclosure includes but is not limited to the following advantages:

[0054] 1. For the above-mentioned polarized table lamp 10, polarized lighting is adopted by using the polarizing member 323. The settings of the first lighting wall 3231, the second lighting wall 3232, the polarizing wall 3233 and the third lighting wall 3234 enable the light rays irradiated by the light source member 322 to exit through the polarizing member 323 at the lighting angle of the lamp formed by the extension line of the first lighting wall 3231 and the extension line of the second lighting wall 3232 and the polarized lighting angle formed by the extension line of the polarizing wall 3233 and the extension line of the third lighting wall 3234. Furthermore, the lighting range of the table lamp is relatively wide. Even if an object is relatively close to the light-emitting part of the table lamp, there are still some light rays reflected and emitted through the polarizing wall 3233 of any polarizing unit. Therefore, the polarized lighting performance is good, and the lighting experience of the table lamp can be guaranteed. Among them, under the action of the polarizing wall 3233, the polarized lighting angle is relatively large, and unidirectional extended polarized lighting can be realized.

[0055] 2. The rotating member 324 horizontally rotates and adjusts the polarized lighting position of the light source member 322 by adjusting the rotation angle of the lighting housing 321, so that on the basis of the light rays being guided and emitted at the lighting angle of the lamp, a wider lighting range can be achieved.

[0056] The above embodiments only represent several implementation manners of the present disclosure. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the disclosed patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several deformations and improvements can still be made, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent shall be subject to the appended claims.
