Description

Technical Field

[0001] The utility model relates to the field of study lamps, in particular to a full-spectrum eye-protection study lamp. Background Art

[0002] Study lamps are lighting devices designed specifically for learning environments. They usually have some specific functions to improve learning efficiency and protect eyesight.

[0003] In the prior art, most study lamps are made of ordinary LED light sources. However, LEDs are point light sources, and localized excessive light can strongly irritate the eyes. Furthermore, LED lamps have a small luminous area, a large amount of light per unit area, and uneven light distribution, which can easily result in strong illumination in the center and weak illumination in the periphery. When reading or writing, books and desks will reflect a certain amount of light, which is commonly known as glare, causing discomfort to the human eye. Furthermore, the LED spectrum contains a large amount of blue light, and prolonged exposure to it can lead to symptoms such as macular degeneration, decreased vision, and reduced color resolution. The utility model patent with announcement number CN 206831359 U provides an OLED shadowless eye-protection study lamp. By disposing multiple OLED light panels, the light source surfaces of all OLED light panels overlap on the projection surfaces of the desktop, thereby forming a shadowless area on the desktop. This eliminates the glare or shadow problems caused by ordinary desk lamps and achieves an eye-protection effect.

[0004] However, OLED panels, as a new display technology, offer advantages such as high contrast, wide color gamut, fast response, and ultra-thin design. They are primarily used in high-end consumer electronics, such as smartphones, TVs, tablets, and in-car displays, which require high display quality. However, these panels are relatively expensive. Furthermore, the OLED shadowless eye-protection study lamp requires multiple OLED panels, further increasing production costs and hindering its widespread adoption. Summary of the Invention

[0005] In view of this, the present invention provides a full-spectrum eye-protection study lamp that uses a full-spectrum LED light panel as a light source to solve the above problems.

[0006] A full-spectrum eye-protection study lamp comprises a lamp body and a fixed frame rotatably connected to the lamp body.

[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the scope of protection of the present invention.

[0019] like Figures 1 to 3, which is a schematic diagram of the structure of a full-spectrum eye-protection study lamp provided by the present invention. The full-spectrum eye-protection study lamp includes a lamp body 10 and a fixing bracket 20 rotatably connected to the lamp body 10. It is conceivable that the full-spectrum eye-protection study lamp should also include other functional components, such as electrical connection components and mounting components. These are all well known to those skilled in the art and will not be further described here.

[0020] The lamp body 10 includes a lamp housing 11, a full-spectrum LED light board 12 arranged in the lamp housing 11, a diffusion plate 13 arranged on one side of the full-spectrum LED light board 12, a prismatic plate 14 arranged on one side of the diffusion plate 13, a control board 15 arranged between the full-spectrum LED light board 12 and the diffusion plate 13, a plurality of pressure strips 16 arranged between the full-spectrum LED light board 12 and the diffusion plate 13, and a fixing plate 17 arranged on the side of the full-spectrum LED light board 12 opposite to the diffusion plate 13.

[0021] The lamp housing 11 includes a lamp housing body 111 , a receiving cavity 112 disposed on the lamp housing body 111 , a cover plate 113 disposed on one side of the receiving cavity 112 , and a touch panel 114 disposed on the outer wall of the lamp housing body 111 .

[0022] The lamp housing body 111 can be configured according to the design of the learning lamp and is used to protect the functional components housed in the housing cavity 112, such as the full-spectrum LED light board 12, the diffuser plate 13, the prismatic plate 14, the control board 15, the pressure strip 16, the fixing plate 17, and related electrical wiring. The lamp housing body 111 itself is a prior art and will not be further described here.

[0023] The accommodating cavity 112 is used to accommodate the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control board 15, the pressure strip 16, the fixing plate 17 and related electrical connection lines, so as to facilitate the combination of the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control board 15, the pressure strip 16, and the fixing plate 17 to form the lamp body 10 as a whole. The size of the accommodating cavity 112 is adapted to the size of the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control panel 15, the pressure strip 16, and the fixing plate 17, and a plurality of step structures or slot structures adapted to the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control panel 15, the pressure strip 16, and the fixing plate 17 are provided on the inner side wall of the accommodating cavity 112 to facilitate the assembly of the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control panel 15, the pressure strip 16, and the fixing plate 17.

[0024] The cover plate 113 is arranged on the side of the fixing plate 17 opposite to the full-spectrum LED light board 12, and is used to close the accommodating cavity 112 to enclose the full-spectrum LED light board 12, the diffuser plate 13, the prism plate 14, the control board 15, the pressure strip 16, and the fixing plate 17 in the accommodating cavity 112, thereby preventing dust, debris, etc. from entering the accommodating cavity 112 during long-term use of the learning lamp, causing pollution to the full-spectrum LED light board 12, the diffuser plate 13, and the prism plate 14, and affecting the lighting effect of the learning lamp.

[0025] The touch panel 114 is fixedly mounted on the outer wall of the lamp housing 111 and is electrically connected to the control panel 15. The touch panel 114 is used to control the on / off function and the number of gears of the learning lamp. Therefore, the touch panel 114 includes at least an on / off key, a gear-up key, and a gear-down key. During use, the brightness of the learning lamp can be adjusted by touching the gear-up key or the gear-down key according to the user's needs. It is conceivable that corresponding function keys, such as light color control, can be added to the touch panel based on the design requirements of the learning lamp and the control functions of the control panel 15.

[0026] The full-spectrum LED light board 12 is composed of a plurality of LED lamp beads arranged in an array. The LED lamp beads used in the full-spectrum LED light board 12 are full-spectrum LED lamp beads. Full-spectrum LED lamp beads use lighting technology that simulates natural light and improves lighting quality by providing a spectrum close to sunlight, such as lighting with a color temperature of 4000K. It has good color reproduction and is free of blue light hazards. Therefore, it can reduce damage to the user's eyes caused by long-term study and reading, and protect the user's eye health. In addition, the full-spectrum LED light board is driven by a power supply and emits light synchronously to form a surface-emitting lighting effect, thereby avoiding the use of a point light source, that is, a single lamp bead, to provide lighting that causes local light to be too bright, which will strongly irritate the eyes. In addition, the light-emitting area is small and the light emission per unit area is large, resulting in uneven light distribution, which easily causes strong illumination in the center and weak illumination in the surrounding area, causing glare and making the human eye feel uncomfortable.

[0027] The diffuser plate 13 can be made of a variety of materials, such as PMMA (polymethyl methacrylate) and PC (polycarbonate), to meet the optical performance and design requirements of different LED lamps. The diffuser plate 13 is arranged on the side of the full-spectrum LED light board 12 used for lighting. It is used to diffuse the light emitted by the full-spectrum LED light board 12, evenly dispersing the light emitted by the full-spectrum LED light board 12, thereby reducing glare and improving visual comfort. While maintaining a high light transmittance, it also achieves good light source concealment, allowing the study lamp to provide efficient, uniform, and soft lighting effects.

[0028] The surface structure of the prism plate 14 is in a consistent grid and inverted pyramid shape, which is used to change the beam angle, increase the brightness of the target lighting area, and at the same time suppress the brightness of lamps in non-lighting areas, control glare, and thus improve the comfort and health of lighting.

[0029] The control board 15 and the touch panel 114 are correspondingly disposed on the inner side of the lamp housing body 111 and are electrically connected to the full-spectrum LED light board 12 and the touch panel 114 to form a control circuit for adjusting parameters such as the brightness and color of the full-spectrum LED light board 12. Therefore, it can be expected that the control board 15 should include corresponding functional modules such as control circuits and control software, which are all well known to those skilled in the art and will not be further described here.

[0030] Multiple beadings 16 are arranged along the sidewalls of the accommodating cavity 112, with two independent beadings 16 provided on each side. The two beadings 16 on the same side are spaced apart based on the size of the control board 15 to facilitate installation of the control board 15 and the power cord 25 described below. The beadings 16 have an H-shaped cross-section, with one open end of the H facing toward the diffuser plate 13. One vertical side of the H-shape is positioned against the housing body 111, while the other side is positioned above the diffuser plate 13, thereby restricting the position of the diffuser plate 13 and the prismatic plate 14.

[0031] The fixing plate 17 can be made of semi-hard aluminum plate, which is used to fix the full-spectrum LED light board 12. Specifically, the fixing plate 17 is fixed to the full-spectrum LED light board 12 by screws, and is fixed to the step structure in the accommodating cavity 112 by screws.

[0032] The fixing frame 20 includes a first frame 21 rotatably connected to the lamp body 10, a second frame 22 retractably connected to the first frame 21, a slide rail assembly 23 for connecting the first frame 21 and the second frame 22, a rotating connecting member 24 for connecting the lamp body 10 and the first frame 21, and a power cord 25 accommodated in the first frame 21 and the second frame 22.

[0033] The first frame 21 includes a first frame body 211 fixedly connected to the rotating connecting member 24, two first slide rail mounting grooves 212 arranged on both sides of the first frame body 211, and a sliding limit card 213 arranged on the side of the first frame body 211 close to the lamp body 10.

[0034] One side of the first frame body 211 is screwed to the rotating connector 24, thereby forming a rotational connection with the lamp body 10. The first frame body 211 can have a U-shaped cross-section to accommodate the second frame 22, and multiple screw holes for mounting the slide rail assembly 23 are provided on both sides of the first frame body 211 to facilitate installation of the slide rail assembly 23.

[0035] The first slide rail mounting groove 212 is adapted to the structure and size of the slide rail assembly 23 and is used to accommodate the slide rail assembly 23 so as to facilitate installation of the slide rail assembly 23 in the first frame body 211 .

[0036] The sliding limit card 213 is arranged at one end of the first slide rail mounting groove 212 toward the lamp body 10, and is used to limit the sliding distance of the slide rail assembly 23 toward the lamp body 10, thereby preventing the slide rail assembly 23 and the second frame 22 from passing out from the first frame body 211 toward the side of the lamp body 10 when the first frame 21 and the second frame 22 are slid and retracted, thereby damaging the lamp body 10.

[0037] The second frame 22 includes a second frame body 221 fixedly connected to the slide rail assembly 23 , and a power line limiting card 222 disposed on the second frame body 221 .

[0038] The second frame body 221 is a U-shaped setting adapted to the first frame body 211. When combined, the second frame body 221 is arranged opposite to the first frame body 211 and is accommodated in the first frame body 211. A plurality of fixing screw holes are provided on the second frame body 221, so that the learning lamp can be fixedly installed on a wall, a cabinet or other fixed object by means of fasteners such as screws, for easy use. It is conceivable that a supporting structure such as a base can also be provided on one side of the free end of the second frame body 221, so that the learning lamp can be placed directly on a desktop for use. The base is a prior art known to those skilled in the art and will not be described in detail here.

[0039] The power line limit card 222 can be formed by bending the opening of the second frame body 221 toward one side of the first frame body 211. The end of the power line 25 can be fixedly clamped on the power line limit card 222 and can be connected to the power supply through the opening.

[0040] The slide rail assembly 23 includes a guide rail 231 fixedly connected to the first frame 21 and a sliding sleeve 232 sleeved on the outer side of the guide rail 231 .

[0041] The guide rail 231 is received in the first slide rail mounting groove 212 and is fixedly connected to the first frame body 211 using corresponding fasteners such as round head screws.

[0042] The sliding sleeve 232 is slidably mounted on the guide rail 231 and is fixedly connected to the second frame body 221 using corresponding fasteners such as round head screws. When the second frame body 221 is pulled, the sliding sleeve 232 reciprocates along the sliding rail 231, thereby achieving the purpose of adjusting the length of the fixing frame 20.

[0043] The rotating connecting member 24 is used to allow the first frame 21 to be rotatably mounted on the lamp housing 11. It can be made of a workpiece that can be flipped, such as a hinge. During installation, one side of the rotating connecting member 24 can be fixedly connected to the lamp housing 11 by fasteners such as screws, and the other side is fixedly connected to the first frame 21, so that a rotating connection can be formed between the lamp body 10 and the fixing frame 20. Therefore, when using the learning lamp, the irradiation distance of the lamp body 10 can be adjusted by adjusting the length of the fixing frame 20 to adjust its lighting range. At the same time, the angle between the lamp body 10 and the fixing frame 20 can be rotated to adjust the irradiation angle of the light, so that the learning lamp can meet the irradiation needs of different positions and angles.

[0044] The power cord 25 includes a power cord body 251 and a plurality of protective coils 252 arranged at both ends of the power cord body 251 and at the contact point between the power cord body 251 and the lamp housing 11. One end of the power cord body 251 is fixedly connected to the lamp body 10, and the other end is connected to an external power supply to power the lamp body 10 during use, driving the lamp body 10 to emit light. The protective coils 252 can be made of soft insulating materials such as silicone and rubber. They are located at the connection points at both ends of the power cord body 251 and at the contact point between the power cord body 252 and the lamp housing 11. They are used to protect the power cord body 251 to prevent the power cord body 251 from being damaged by friction with the lamp housing 11 or the second frame 22 during use, thereby preventing leakage.

[0045] Compared with the prior art, the full-spectrum eye protection study lamp provided by the present invention has a full-spectrum LED lamp board 12 that is made of full-spectrum LED lamp beads, which can emit light close to the color temperature of the sun, such as 4000k color temperature, thereby providing users with high-quality blue light-free lighting effects and reducing damage to the eyes caused by long-term study. At the same time, since the full-spectrum LED lamp board 12 is composed of a plurality of full-spectrum LED lamp beads arranged in an array, the full-spectrum LED lamp board 12 forms a surface luminous effect, and the diffusion plate 13 is provided on the light-emitting side of the full-spectrum LED lamp board 12 to evenly diffuse the light of the full-spectrum LED lamp board 12. The prism plate 14 is also provided on one side of the diffusion plate 13, which can increase the brightness of the lighting area of ​​the study lamp and suppress the brightness of the lamp in the non-lighting area, so that the study lamp can provide efficient, uniform and soft lighting effects. The fixing frame 20 and the lamp body 10 are rotatably connected via the rotating connector 24. The light's irradiation angle can be adjusted by rotating the lamp body 10. Furthermore, the first frame 21 and the second frame 22 of the fixing frame 20 are designed to be retractable, so the irradiation range of the lamp body 10 can be further adjusted by adjusting the length of the fixing frame 20. In summary, the full-spectrum eye-protection study lamp provides uniform and soft illumination, providing users with efficient, high-quality lighting effects. The light's irradiation angle can be adjusted at multiple angles to meet the user's lighting needs, making it suitable for long-term study use.
