Description

Technical Field

[0001] The invention relates to the technical field of eye protection lamps, and more specifically, to an eye protection lamp with adjustable brightness for computers. Background Art

[0002] When using a computer, the blue light emitted by its screen may cause eye fatigue, dryness and blurred vision. In order to change the blue light emitted by the screen, many computer users choose to use an eye protection lamp. Eye protection lamps are usually designed with the function of reducing blue light, which can help alleviate these discomforts.

[0003] However, when using traditional eye protection lamps, they generally adjust the brightness they emit to alleviate the emission of blue light from the computer through different brightness. The second way is to adjust the color temperature of the eye protection lamp itself to change the user's visual experience of the computer through the color temperature to avoid fatigue, dryness and blurred vision.

[0004] There are many kinds of color temperature, the most common ones are yellow, white, blue, red and other colors. Different colors have different protective effects on the eyes. Among them, yellow belongs to the warm color system, and its color temperature is low, which is very suitable for use at night. It can reduce glare, reduce eye fatigue and help improve sleep quality. White belongs to the neutral color system, the color is very soft, suitable for all-day use, which can maintain visual comfort while reducing eye fatigue. Blue is a brighter cold color. Using a stronger blue at night will affect the quality of sleep, but if a low-intensity blue light eye protection lamp with a warm light source is used, it can have a good eye protection effect. Red belongs to the warm color system, which is softer to use and helps to improve attention, but traditional eye protection lamps are often single-color temperature. In the process of adjusting the color temperature, only the depth of the color temperature can be adjusted, and the type of color temperature cannot be directly changed. Therefore, we designed an eye protection lamp with adjustable brightness for computers. Summary of the invention

[0012] As a further optimization solution of the present invention, the light-emitting component includes a circuit board, and two ends of the circuit board are respectively connected to two conductive terminals; An LED lamp is arranged on the circuit board, and a conductive feeler of the LED lamp forms a soldering point with the circuit board, and the soldering point is covered with a coating.

[0016] The beneficial effects of the present invention are: 1. The eye protection lamp with adjustable brightness for computers described in the present invention can rotate the first gear through the back and forth driving of the arc frame, thereby acting on the rotating tube, so that the rotating tube drives the first light-transmitting cover, the second light-transmitting cover, the third light-transmitting cover, and the fourth light-transmitting cover to rotate. In this way, the first light-transmitting cover, the second light-transmitting cover, the third light-transmitting cover, and the fourth light-transmitting cover can be specified to be used with the fixed cover, which is convenient for users to use different color temperatures according to different environments to achieve the best eye protection effect, and the color temperature carried by the first light-transmitting cover, the second light-transmitting cover, the third light-transmitting cover, and the fourth light-transmitting cover can also be the same. When the color temperature is the same, the depth of the color temperature is different, which is convenient for adjusting the depth of the color temperature, and subsequently, different colors of color temperature sheets can be bonded to the light outlet of the fixed cover to achieve the effect of adjusting the color temperature.

[0017] 2. The eye protection lamp with adjustable brightness for computers described in the present invention drives the movement of the threaded column by rotating the screw rod. With the help of the limiting function of the threaded column and the use of the arc frame, the arc frame can drive the cleaning arc plate to move continuously. The cleaning arc plate can clean and collect impurities on the surface of the light-transmitting cover to prevent the impurities from affecting the light exposure. The light-transmitting cover is located on the inner side of the fixed cover and is less likely to be contaminated by large particles of impurities. The arc frame can also drive the sliding plate under the limiting effect of the threaded column, and the sliding plate can block the light-transmitting cover. In this way, the overall illumination range of the light-transmitting cover can be changed, so that the illumination range is more closely aligned with the display area of ​​the screen to avoid light leakage.

[0018] 3. The computer eye protection lamp with adjustable brightness described in the present invention can also drive the first tooth plate to move through the arc frame, and the first gear can cause the fan blades to rotate. The fan blades can accelerate the air flow in the protective cover to dissipate heat for the circuit board and LED lamp in the light-transmitting cover, and with the help of bimetallic strips, automatic temperature sensing can be achieved. After the light-transmitting cover reaches a certain temperature, the second tooth plate will act on the fan blades to accelerate the air flow in the protective cover, and the top of the protective cover itself is a hollow structure, which is more convenient for heat dissipation.

[0019] 4. After the LED lamp has been used for a period of time, the heat generated by the LED lamp dissipates from the heat dissipation surface of the circuit board and gathers in the light cover. The solder joints are coated with a coating to accelerate the speed of heat radiation. The coating increases the contact area between the solder joints and the air, thereby expanding the heat dissipation area of ​​the circuit board and accelerating the heat dissipation of the light cover. The through holes opened on both sides of the light cover, combined with fan blades, can further promote the heat dissipation in the light cover. Since the heat dissipation effect is improved, the heat will not accumulate too much, and its energy consumption will be reduced accordingly, which is more energy-saving.

DETAILED DESCRIPTION

[0022] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0023] like Figures 1 to 5 , Fig.10 , Fig.11 , Fig.13 As shown, an eye protection lamp with adjustable brightness for computers according to an embodiment of the present invention comprises a protective cover 1, and a lamp holder 2 is fixedly connected to the inner walls on both sides of the inner cavity of the protective cover 1; A fixed cover 3 is arranged between the two lamp holders 2, and the left and right sides of the fixed cover 3 are fixedly connected to the lamp holders 2 through a plurality of auxiliary rods 9; A variable lamp tube mechanism is located inside the fixed cover 3 and is rotatably connected to the fixed cover 3, and the variable lamp tube mechanism is used to change the illumination brightness of the lamp tube; A shielding and cleaning mechanism is fixedly mounted on the fixed cover 3, and is used to shield and clean the variable lamp tube mechanism; An automatic cooling mechanism is located between the protective cover 1 and the variable lamp tube mechanism, and is used to accelerate the air flow in the protective cover 1; The variable lamp tube mechanism includes a rotating tube 401, which passes through the fixed cover 3 and is rotatably connected to the fixed cover 3; A conductive terminal is arranged inside the rotating tube 401, and the conductive terminal is connected to the lamp holder 2, and a light-emitting component is installed between the two conductive terminals; a first light-transmitting cover 405, a second light-transmitting cover 414, a third light-transmitting cover 415, and a fourth light-transmitting cover 416 are fixedly connected to the rotating tube 401, and the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 are combined into a cylindrical shape, and through holes are opened on the left and right sides of the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 have different light transmittances; the variable lamp tube mechanism also includes a crown Gear 402, crown gear 402 is fixedly mounted on rotating tube 401; a first gear 404 is meshed with the crown gear 402, a first rotating shaft 403 is fixedly connected to the first gear 404, a fixed plate 413 is fixedly connected to the top of the first gear 404, and a toggle plate 412 is fixedly connected to the top of the fixed plate 413; a second rotating shaft 408 is rotatably mounted on the inner wall of the top inner cavity of the protective cover 1, a plurality of connecting rods 411 are fixedly connected to the second rotating shaft 408, a second gear 409 is fixedly connected to the connecting rod 411, a tooth groove is penetrated through the second gear 409, and the toggle plate 412 is located inside the tooth groove; a mounting plate 410 is rotatably connected to the first rotating shaft 403, and the mounting plate 410 is fixedly connected to the protective cover 1; The shielding and cleaning mechanism also includes an arc frame 406; It should be noted that by moving the arc frame 406, the arc frame 406 drives the first tooth plate 407 to approach the first gear 404. Due to the action of the shifting piece 412, the rotation of the first gear 404 does not affect the first rotating shaft 403. However, when the first arc frame 406 returns to its original position, the first tooth plate 407 will also act on the first gear 404, and the first gear 404 will act on the paddle plate 412 by means of the tooth groove, so that the paddle plate 412 drives the fixed plate 413 to rotate, and the fixed plate 413 drives the first rotating shaft 403 to rotate, and the first rotating shaft 403 drives the crown gear 402 to rotate, and the crown gear 402 drives the rotating tube 401 to rotate, and the rotating tube 401 drives the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 to rotate, so that the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 can be effectively switched; Since the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 can be light-transmitting covers of different color temperatures, it is convenient for users to select different light-transmitting covers for use according to actual conditions, which can achieve a better eye protection effect; Furthermore, the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 can be used in combination, so that the brightness emitted by the LED light 804 will act on two different light-transmitting covers, and the color temperatures that appear will be superimposed. The superposition of different color temperatures can enrich the expression and visual effects of the display screen and provide richer colors and atmosphere. Furthermore, the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416 can also be light-transmitting covers with the same color temperature but different depths, so that the depth of the color temperature can be simply adjusted to adjust the degree of eye protection, and color temperature sheets of different colors are installed at the bottom of the fixed cover 3 to achieve the switching of different color temperatures, and better adjustment can be made in combination with the depth of the color temperature; Furthermore, a sawtooth strip microstructure may be provided inside the fourth light-transmitting cover 416 to further enhance the light scattering effect of the transparent cover plate; For example, Fig.11 As shown, the first microstructure region may include a plurality of first sawtooth rod-shaped structures, the second microstructure region may include a plurality of second sawtooth rod-shaped structures, and the third microstructure region may include a plurality of third sawtooth rod-shaped structures; the vertex angle of each first sawtooth rod structure preferably falls within the range of 70° to 90°; the vertex angle of each second sawtooth rod structure preferably falls within the range of 90° to 120°; the vertex angle of each third sawtooth rod structure preferably falls within the range of 120° to 150°; By designing that the microstructures are distributed from the roof portion to the side arm portion in a sequence from dense to sparse, the vertex angle gradually increases, and after the light emitted by the LED lamp 804 is incident on the first microstructure region, the light scattering effect of the transparent cover can be further enhanced in the second microstructure region and the third microstructure region; Therefore, the light-emitting angle of the LED lamp 804 can be increased, so that the light emitted from the transparent cover can have a more uniform brightness distribution.

[0024] like Figures 8 to 9 As shown, the shielding cleaning mechanism includes a hollow box 501, the hollow box 501 is fixedly connected to the fixed cover 3, a sliding plate 503 is slidably connected inside the hollow box 501, a cleaning arc plate 505 is fixedly connected to the sliding plate 503, and a storage box 506 is fixedly connected to the cleaning arc plate 505; The obstruction cleaning mechanism also includes an arc frame 406, which is fixedly connected to the cleaning arc plate 505 and the storage box 506; a hollow column 502 is fixedly installed at the bottom of the arc frame 406, and a screw 508 is rotatably connected to the hollow column 502. A threaded column 507 is slidably connected inside the hollow column 502, and the threaded column 507 is connected to the screw 508.

[0025] It should be noted that, by rotating the screw 508, the screw 508 will drive the threaded column 507 to move, and the threaded column 507 will extend into the groove of the cleaning arc plate 505, thereby limiting the cleaning arc plate 505; When the arc frame 406 is driven to move, the arc frame 406 will drive the cleaning arc plate 505 to move, so that the cleaning arc plate 505 can clean the impurities on the surface of the light-transmitting cover, and the cleaned impurities will also fall into the storage box 506 for easy storage; The light-transmitting cover is located inside the fixed cover 3 and is shielded by the fixed cover 3, which not only can better protect the light-transmitting cover, but also can prevent some impurities from adhering to the light-transmitting cover.

[0026] like Figures 8 to 9 As shown, a groove is provided inside the cleaning arc plate 505 , the threaded column 507 is plugged into the groove, the limiting frame 504 is slidably connected inside the groove, and the limiting frame 504 is fixedly connected to the sliding plate 503 .

[0027] It should be noted that, by rotating the screw rod 508, the screw rod 508 will drive the threaded column 507 to move, and the threaded column 507 will extend to the inside of the limit frame 504. In this way, when the arc frame 406 moves, it can also drive the arc plate to move. The arc plate moves out of the hollow box 501, thereby blocking the light-transmitting cover. In this way, the illumination range of the light-transmitting cover can be changed so that its illumination range can be consistent with the display area of ​​the display screen, thereby avoiding filtering and leakage of light, which affects the visual experience around the display screen.

[0028] like Figure 6 to Figure 7 As shown, the top end of the arc frame 406 extends to the inside of the protective cover 1 and is slidably connected to the protective cover 1, and a first tooth plate 407 is fixedly connected to the arc frame 406; The automatic cooling mechanism also includes a second magnetic block 702, and the second magnetic block 702 and the first magnetic block 604 are magnetically repelled; a slide bar 704 is slidably connected to the second magnetic block 702, and a support frame is fixedly connected to the slide bar 704, and the support frame is fixedly connected to the protective cover 1, and a positioning column 703 is fixedly connected to the slide bar 704, and the positioning column 703 is fixedly connected to the protective cover 1, and a common spring 705 is sleeved on the slide bar 704, and the two ends of the common spring 705 are respectively connected to the second magnetic block 702 and the support frame; The second magnetic block 702 is fixedly connected with a positioning plate 701, the positioning plate 701 is fixedly connected with the protective cover 1, and the positioning plate 701 is fixedly connected with a second tooth plate 710; The automatic cooling mechanism also includes a positioning frame 708, which is fixedly connected to the support frame; the positioning frame 708 is rotatably connected to a fourth shaft 706, the fourth shaft 706 is fixedly connected to a third gear 709, and the fourth shaft 706 is fixedly connected to a fan blade 707.

[0029] It should be noted that when the threaded column 507 is completely located inside the hollow column 502, the arc frame 406 is driven, and the arc frame 406 drives the first tooth plate 407 to move. The first tooth plate 407 can act on the second gear 409 to rotate the second gear 409, so that the second gear 409 can drive the fourth shaft 706 to rotate, thereby rotating the fan blades 707. The fan blades 707 can accelerate the air flow in the protective cover 1 and accelerate the heat loss in the protective cover 1.

[0030] like Figure 6 to Figure 7 As shown, the automatic cooling mechanism includes a heat conducting plate 601, which is fixedly mounted on the fixed cover 3; the heat conducting plate 601 is in contact with the first light-transmitting cover 405, the second light-transmitting cover 414, the third light-transmitting cover 415, and the fourth light-transmitting cover 416; a heat conducting tube is fixedly mounted on the heat conducting plate 601, a positioning box 603 is fixedly connected to the heat conducting tube, a third rotating shaft 606 is rotatably connected inside the heat conducting tube, a bimetallic spring 602 is arranged inside the heat conducting tube, and the bimetallic spring 602 is mounted on the third rotating shaft 606; the top end of the third rotating shaft 606 passes through the third rotating shaft 606 and is rotatably connected to the positioning box 603, a connecting plate 605 is fixedly connected to the third rotating shaft 606, and a first magnetic block 604 is fixedly connected to the connecting plate 605.

[0031] It should be noted that, since the light-transmitting cover and the heat-conducting plate 601 are in contact with each other, the heat on the light-transmitting cover will be transferred to the heat-conducting plate 601. As the heat is transferred, the heat will act on the bimetallic spring 602. The bimetallic spring 602 will be deformed and rotated due to the heat, thereby enabling the fourth rotating shaft 706 to rotate. The rotation of the fourth rotating shaft 706 will drive the connecting plate 605 to rotate, and the connecting plate 605 will drive the first magnetic block 604 to rotate. When the first magnetic block 604 rotates to a specified position, the first magnetic block 604 will act on the second magnetic block 702, and the second magnetic block 702 will move the second tooth plate 710, so that the second tooth plate 710 will rotate the second gear 409, and the second gear 409 can drive the fourth shaft 706 to rotate, thereby rotating the fan blades 707 to achieve the effect of automatic heat dissipation.

[0032] like Fig.12 As shown, the light-emitting component includes a circuit board 802, and both ends of the circuit board 802 are respectively connected to two conductive terminals; an LED lamp 804 is arranged on the circuit board 802, and the conductive antenna of the LED lamp 804 forms a solder joint 803 with the circuit board 802, and the solder joint 803 is covered with a coating 801.

[0033] It should be noted that after the LED lamp 804 is used for a period of time, the heat generated by the LED lamp 804 is dissipated from the heat dissipation surface of the circuit board 802 and gathered in the light-transmitting cover. The solder joint 803 is coated with a coating 801 to accelerate the heat radiation speed. The coating 801 increases the contact area between the solder joint 803 and the air, thereby expanding the heat dissipation area of ​​the circuit board 802 and accelerating the heat dissipation of the light-transmitting cover. The through holes on both sides of the light-transmitting cover make the light-transmitting cover communicate with the inner cavity of the protective cover 1, so that the airflow can flow continuously; Furthermore, since the fan blades 707 can be started manually or automatically to accelerate the gas flow in the protective cover 1, the gas flow in the light-transmitting cover will also be driven, thereby accelerating the overall heat dissipation effect, better conducting heat out of the protective cover 1, and avoiding heat accumulation.

[0034] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
