Description

Technical Field

[0001] The present invention relates to the technical field of LED lamps, and in particular to an eye-protection LED lamp. Background Art

[0002] Eye protection desk lamps mainly transform ordinary low-frequency flicker into high-frequency flicker. By using variable-frequency electronic ballasts, the flicker speed is accelerated to exceed the nerve reaction speed of the human eye, making people feel that the light is more stable and reducing the damage of flicker to the eyes. In addition, some eye protection desk lamps use LED technology, taking advantage of the characteristics of no flicker and no stroboscopic. By controlling the current drive, the light source is stable, and polarized film light guide technology is used to make the light diverge evenly to avoid glare. Eye protection desk lamps are mainly used for learning. They can accurately illuminate the learning area, reduce the interference of ambient light, and help users focus on the learning content.

[0003] In the application scenarios of traditional eye-protection desk lamps, their lighting range is usually fixed and difficult to flexibly adjust according to actual usage needs. When adjusting the lighting range of the desk lamp, it is mainly achieved by changing the height of the lampshade. However, this adjustment method has obvious limitations. In larger rooms or environments with high requirements for light intensity, even if the height of the lampshade is adjusted to the maximum range, the light can only be irradiated outward through the lampshade, resulting in a relatively small maximum lighting range. In addition, the distribution of light is also limited by the structure of the lampshade, making it difficult to achieve a wide range of lighting effects, and thus unable to meet diverse lighting needs. Moreover, when the desk lamp is irradiating, the illuminated area is brighter and the surrounding light is dim, which will cause eye fatigue.

[0004] In order to solve the above problems, this application proposes an eye-protection LED lamp. Summary of the Invention

[0014] As a further optimization scheme of the present invention, reflective sheets are provided on the front and back sides of the reflective plate, and second screws are installed on both sides of the reflective plate. The two second screws are rotated away from one end and pass through the two sides of the reflective cover body respectively.

[0015] As a further optimization solution of the present invention, a shading component is installed on the reflective cover body, and the shading component controls the range of light reflected by the reflective cover body.

[0016] As a further optimization scheme of the present invention, the shading assembly includes a fixed frame, which is mounted on the reflective cover body.

[0019] As a further optimization solution of the present invention, a reflective film is attached to the inner wall of the reflective cover.

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. The present invention can illuminate the room upwards through the auxiliary light on the LED lamp body while using the LED lamp body for illumination. The reflector body provided above the auxiliary light can reflect the light irradiated upwards by the auxiliary light, thereby expanding the illumination range. The reflector body acts as a reflector above the auxiliary light, creating a stepped illumination effect, supplementing the illumination of areas not illuminated by the LED lamp body, reducing the problem of a large difference in intensity between the illuminated area of the LED lamp body and the ambient light, thereby avoiding eye fatigue caused by local overbrightness or overdarkness, and providing users with a more comfortable and uniform lighting environment. In addition, the distance between the reflector body and the auxiliary light is adjustable, further expanding the supplementary illumination range and meeting diverse lighting needs. It is suitable for larger rooms or scenes with high requirements for light intensity.

[0022] 2. When in use, the reflector body of the present invention can change the angles of the two reflectors therein. The two reflectors can be rotated within the reflector body so that they approach each other to form an inverted eight structure. When the auxiliary lamp shines light upward, the light is reflected outward by the two reflectors. The cooperation between the reflector body and the two reflectors can reflect light over a wider range. This design not only improves the efficiency of light utilization, but also allows the reflection direction and range of light to be flexibly adjusted according to the actual usage scenario, further enhancing the flexibility and adaptability of the LED desk lamp main body lighting, and better meeting the lighting needs of users in different positions and angles.

[0023] 3. Although the reflector of the present invention can adjust the reflection angle, the reflector is always adjusted inside the reflector body, and the reflection angle is limited. When the user is doing homework, there are several exercise books, and the user normally needs to switch the positions of the exercise books back and forth to achieve sufficient lighting on the exercise books. However, the light reflected by the reflector body and the reflector is uniform, and it is impossible to supplement light for a small area. The present invention provides a reflective component in the reflector. When in use, it is only necessary to pull the reflective component out of the storage slot, and the reflective switching part on the reflective component can reflect light to a small area that needs supplement light. For example, when the user switches the position of the exercise book back and forth when doing homework, sufficient lighting can be guaranteed on the exercise book, solving the problem that traditional desk lamps are difficult to supplement light for a small area, improving the targeted lighting, meeting the user's lighting needs in a specific local area, and improving the efficiency and comfort of learning and working;

[0024] 4. In actual use, the reflective switching element of the present invention can be flipped between the two loading rods to switch the position of the silver reflective coating and the white reflective coating on the reflective block. The silver reflective coating on one side of the reflective block can make the reflected light brighter, suitable for scenes requiring high-brightness lighting. The white reflective coating on the other side of the reflective block can make the reflected light more gentle, suitable for use in situations requiring soft light to reduce visual stimulation. Users can freely switch the brightness according to actual needs to meet the light brightness requirements of different scenes and personal preferences, further improving the user experience and application range of the LED desk lamp.

[0025] 5. The shading assembly of the present invention controls the height of the counterweight frame during use through a retractor. Under the weight of the counterweight frame, the shading curtain acts as a gravity pull, gradually unfolding to form a barrier around the bottom of the reflective cover, controlling the angle and range of light emission. This design allows for flexible adjustment of the lighting area and intensity based on the user's specific needs and usage scenarios, preventing excessive or insufficient light diffusion, further optimizing the lighting effect, and improving the lighting quality and practicality of the desk lamp.

[0026] 6. When the main body of the LED desk lamp is not in use, the counterweight frame can be dropped onto the LED lamp body by means of the retractable member, and the blackout curtain is then unfolded, so that the auxiliary lamp is placed in the space formed by the blackout curtain. After the blackout curtain is unfolded, dust can be prevented from adhering to the reflector body and the auxiliary lamp, thereby maintaining the cleanliness and optical performance of the interior of the LED desk lamp body and reducing the influence of dust on light reflection and transmission.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0043] like Figure 1-14 As shown, the present invention provides an eye-protection LED lamp, comprising an LED desk lamp body 1 and a reflective cover body 2;

[0044] The LED desk lamp body 1 includes an LED lamp body 101, an auxiliary lamp 102 is installed on the LED lamp body 101, a reflective cover 2 is installed on the LED desk lamp body 1 and is located above the auxiliary lamp 102, and the distance between the reflective cover 2 and the auxiliary lamp 102 is adjustable;

[0045] Two reflectors 3 are symmetrically installed in the reflector body 2, and the angles of the reflectors 3 in the reflector body 2 are adjustable;

[0046] A receiving slot 31 is provided in the reflector 3. A reflective component 4 is provided in the receiving slot 31. The reflective component 4 can enter and exit the receiving slot 31 to reflect light to a small area.

[0047] The reflective assembly 4 includes a reflective switching element 44 , and the reflective switching element 44 is used to switch the brightness of the reflected light.

[0048] The LED lamp body 101 in the LED desk lamp main body 1 of the present invention serves as the main light source to provide basic lighting. The auxiliary lamp 102 is used to irradiate light upward to provide an auxiliary light source for expanding the lighting range. When the auxiliary lamp 102 is lit, the reflective cover body 2 can reflect the light irradiated upward to form a stepped lighting effect, filling in the area not illuminated by the LED lamp body 101, reducing the difference in intensity between the illuminated area and the ambient light, and avoiding eye fatigue. When the auxiliary lamp 102 irradiates light upward, the light can be reflected outward by adjusting the angle of the reflector 3, so that the reflected light range is wider, the light utilization efficiency is improved, and the lighting flexibility and adaptability are enhanced. The storage slot 31 in the reflector 3 is provided with an accessible reflective component 4. When it is necessary to fill in light to a small area, the reflective component 4 is pulled out, and the light is reflected to the target area through the reflective switching component 44, thereby improving the targeted lighting. The reflective switching component 44 can switch the brightness of the reflected light. Users can choose the appropriate brightness according to actual needs to improve the usage experience and scope of application.

[0049] like Figure 6 ,and Figure 7 As shown, in this embodiment, the reflective assembly 4 also includes a fixing rod 41, a loading part 42 and a loading rod 43. Two fixing rods 41 are symmetrically installed in the storage groove 31. The two fixing rods 41 are both installed with loading parts 42, and the position of the loading parts 42 on the fixing rods 41 is adjustable. The loading rod 43 is installed on the adjacent side of the two loading parts 42, and the reflective switching part 44 is rotatably installed between the two loading rods 43.

[0050] The position of the loading part 42 of the present invention is adjustable on the fixed rod 41, which enables the overall position of the reflective assembly 4 to be adjusted according to the actual fill light requirements. The loading rod 43 installed on the adjacent side of the two loading parts 42 is used to support and install the reflective switching part 44. The reflective switching part 44 is rotatably installed between the two loading rods 43. This structural design enables the reflective switching part 44 to be flexibly flipped to achieve switching between different reflective coatings, thereby meeting the light brightness requirements of different scenes. By adjusting the position of the loading part 42 on the fixed rod 41, the position of the reflective switching part 44 can be changed, thereby more accurately reflecting light to a small area that requires fill light.

[0051] like Figure 7 、 Figure 9 and Figure 10As shown, in this embodiment, the reflective switching component 44 includes a reflective block 441, a third screw 442 and a third nut 443. The third screw 442 is rotatably installed between the two loading rods 43. The reflective block 441 is fixed on the third screw 442 and is located between the two loading rods 43. One end of the third screw 442 rotates through the side of one loading rod 43. The third nut 443 is threadedly sleeved on one end of the third screw 442 and pressed against the side of one loading rod 43. One side of the reflective block 441 is coated with a silver reflective coating 444, and the other side is coated with a white reflective coating 445.

[0052] The present invention can drive the reflective block 441 to rotate by rotating the third screw 442. The third nut 443 is threadedly sleeved on one end of the third screw 442 and pressed against the side of a loading rod 43, thereby fixing the position of the third screw 442 to ensure the stability of the reflective block 441 during the switching process. The silver reflective coating 444 on one side of the reflective block 441 can make the reflected light brighter, which is suitable for scenes requiring high-brightness lighting, such as reading small text or performing fine work. The white reflective coating 445 on the other side can make the brightness of the reflected light softer, which is suitable for use in situations where soft light is needed to reduce visual stimulation. For example, when reading before resting at night, the user can easily switch between different reflective coatings by rotating the third screw 442 to meet diverse lighting needs.

[0053] like Figure 7 and Figure 8 As shown, in this embodiment, the loading member 42 includes a second set block 421, and the second set block 421 is slidably mounted on the two fixed rods 41. The two loading rods 43 are respectively installed on the adjacent sides of the two second sets of blocks 421. The side of the second set block 421 is slidably connected with a limiting rod 422 that presses against the fixed rod 41. One end of the limiting rod 422 is fixed with an end block 423. A spring 424 is mounted on the limiting rod 422, and the two ends of the spring 424 are respectively connected to the second set block 421 and the end block 423.

[0054] The second set block 421 of the loading member 42 is slidably mounted on the fixing rod 41, so that the loading member 42 can slide freely on the fixing rod 41, which is convenient for adjusting the position. The limiting rod 422 slides through the side of the second set block 421 and presses against the fixing rod 41 to prevent the second set block 421 from sliding freely, ensuring that it can be stably fixed after the position is adjusted. The end block 423 is fixed to one end of the limiting rod 422, which is convenient for operating the limiting rod 422. The spring 424 is mounted on the limiting rod 422, and its two ends are respectively connected to the first set block 421 and the second set block 421. The second set of blocks 421 and the end block 423 are connected. When adjusting the position of the second set of blocks 421, the spring 424 plays a buffering role. At the same time, after the adjustment is completed, it helps the limit rod 422 to better press against the fixed rod 41, thereby enhancing the fixing effect. The user pulls the end block 423 to separate the limit rod 422 from the fixed rod 41, and then slides the second set of blocks 421 to adjust the position. After loosening the end block 423, the spring 424 pushes the limit rod 422 to press against the fixed rod 41 again, thereby fixing the position of the loading part 42.

[0055] like Figure 4 、 Figure 5 、 Figure 13 and Figure 14 As shown, in this embodiment, reflective sheets 32 are provided on the front and back sides of the reflector 3, and second screws 33 are installed on both sides of the reflector 3. The two second screws 33 are rotated away from one end and pass through the two sides of the reflector body 2 respectively. Second nuts 34 are threadedly sleeved on the two second screws 33, and the two second nuts 34 are respectively pressed against the two sides of the reflector body 2.

[0056] The reflective sheets 32 arranged on the front and back sides of the reflector 3 increase the reflective effect of the reflector 3 and improve the light reflection efficiency. The second screws 33 installed on both sides of the reflector 3 rotate through the two sides of the reflector body 2. By rotating the second screws 33, the angle of the reflector 3 in the reflector body 2 can be changed, so that the two reflectors 3 form an inverted eight structure, which reflects light over a wider range. Figure 13 and Figure 14 The second nut 34 is threadedly sleeved on the second screw rod 33 and pressed against both sides of the reflector body 2 to fix the angle of the reflector 3. When the angle of the reflector 3 needs to be adjusted, the second nut 34 is loosened and the second screw rod 33 is rotated. After adjusting to a suitable angle, the second nut 34 is tightened to keep the reflector 3 at the corresponding angle, reflecting the light emitted upward by the auxiliary lamp 102 in different directions to expand the lighting range.

[0057] like Figure 1 、 Figure 2 、 Figure 3 and Figure 11As shown, in this embodiment, a shading assembly 5 is installed on the reflective cover body 2, and the shading assembly 5 controls the range of light reflected by the reflective cover body 2; the shading assembly 5 includes a fixed frame 51, the fixed frame 51 is mounted on the reflective cover body 2, the bottom of the fixed frame 51 is connected to a shading curtain 52 mounted on the reflective cover body 2, the bottom of the shading curtain 52 is connected to a counterweight frame 53, and a reel 54 for adjusting the height of the counterweight frame 53 is installed on the fixed frame 51.

[0058] The fixed frame 51 of the shading assembly 5 of the present invention is mounted on the reflective cover body 2 to play a supporting and fixing role. The blackout curtain 52 is connected to the bottom of the fixed frame 51 and is mounted on the reflective cover body 2. It is unfolded under the gravity of the counterweight frame 53 to form a fence around the bottom of the reflective cover body 2 to control the angle and range of light emission. The retracting member 54 is mainly used to adjust the height of the counterweight frame 53, thereby controlling the degree of unfolding of the blackout curtain 52. When it is necessary to narrow the light range, the counterweight frame 53 is lowered by the retracting member 54, the blackout curtain 52 is unfolded more, and the light emission range becomes smaller. Conversely, the counterweight frame 53 is raised, the blackout curtain 52 is retracted, and the light emission range becomes larger.

[0059] like Figure 12 As shown, in this embodiment, the winding member 54 includes a U-shaped block 541, and two U-shaped blocks 541 are symmetrically installed on the fixed frame 51. A winding roller 542 is rotatably installed in the middle of the U-shaped block 541, and one end of the winding roller 542 rotates through one side of the U-shaped block 541 and is fixed with a handle 543. A pull rope 544 is wound around the winding roller 542, and one end of the two pull ropes 544 is respectively connected to the two sides of the counterweight frame 53. A sleeve shaft 545 is installed on one side of the U-shaped block 541 and is sleeved on one end of the winding roller 542. A second bolt 546 is threadedly connected to the sleeve shaft 545 and pressed against the winding roller 542.

[0060] The present invention can drive the winding roller 542 to rotate by rotating the handle 543. When the winding roller 542 rotates, the pull rope 544 will be retracted and released accordingly, thereby realizing the lifting and lowering of the counterweight frame 53. The second bolt 546 is threadedly connected to the sleeve shaft 545 and pressed against the winding roller 542, which is used to fix the position of the winding roller 542 to prevent it from rotating at will. The user can easily control the height of the counterweight frame 53 by turning the handle 543, and then adjust the expansion degree of the blackout curtain 52 to achieve control of the light range.

[0061] like Figure 1 and Figure 2As shown, in this embodiment, the LED desk lamp main body 1 also includes a lamp pole 103 and a base 104, the lamp pole 103 is hinged on the base 104, the LED lamp body 101 is installed on the lamp pole 103, and a first block 21 is slidably sleeved on the lamp pole 103, and a first bolt 211 is threadedly connected to the first block 21 and pressed against the lamp pole 103, an assembly rod 212 is installed on the side of the first block 21, and two first screws 221 are symmetrically installed at one end of the assembly rod 212, and a U-shaped seat 22 that is rotatably sleeved on the two first screws 221 is installed on the reflective cover body 2, and the two first screws 221 are both threadedly sleeved with first nuts 222, and the two first nuts 222 are respectively pressed against the two sides of the U-shaped seat 22.

[0062] The lamp pole 103 of the LED desk lamp main body 1 of the present invention is hinged on the base 104, which is convenient for adjusting the height and angle of the LED lamp body 101 to meet different lighting needs. The first set of blocks 21 is slidably mounted on the lamp pole 103. By tightening or loosening the first bolt 211, the position of the first set of blocks 21 on the lamp pole 103 can be fixed or adjusted. When it is necessary to adjust the height of the reflector body 2 and the LED lamp body 101, loosen the first bolt 211 and adjust the position of the first set of blocks 21 on the lamp pole 103 to adjust the height of the reflector body 2. When it is necessary to adjust the angle of the reflector body 2, loosen the first nut 222 to make the U-shaped seat 22 on the reflector body 2 rotate on the first screw 221. After the angle of the reflector body 2 is adjusted, tighten the first nut 222 to fix the angle of the reflector body 2.

[0063] like Figure 3 As shown, in this embodiment, a reflective film 23 is attached to the inner wall of the reflective cover body 2; the reflective film 23 can reflect the irradiated light.

[0064] The specific working principle of the present invention is as follows:

[0065] When in use, first adjust the position and angle of the LED desk lamp body 1 according to actual needs, and adjust the angle of the lamp pole 103 through the hinged structure of the lamp pole 103 and the base 104 to change the height and illumination direction of the LED lamp body 101. Utilize the sliding of the first set of blocks 21 on the lamp pole 103 and the fixing effect of the first bolt 211 to adjust the distance between the reflector body 2 and the LED lamp body 101. The LED lamp body 101 is turned on as the main light source to provide basic lighting. The auxiliary lamp 102 shines light upward, and the light is directed to the reflector body 2. The reflective film 23 on the inner wall of the reflector body 2 reflects the light of the auxiliary lamp 102, forming a stepped illumination effect, which fills in the light for the area not illuminated by the LED lamp body 101, reduces the difference in light intensity between the illuminated area and the ambient light, and avoids eye fatigue.

[0066] If the range of reflected light needs to be further expanded, the angle of the reflector 3 in the reflector housing 2 can be adjusted by rotating the second screw 33 to change the angle of the reflector 3. The second nuts 34 on both sides of the reflector 3 are used to fix the adjusted angle. The reflective sheets 32 on the front and back sides of the reflector 3 improve the reflection efficiency and make the light reflection range wider.

[0067] When fill light is needed for a small area, the reflective assembly 4 is pulled out from the storage slot 31 of the reflector 3. By adjusting the position of the loading member 42 on the fixing rod 41, the reflective switching member 44 is aligned with the area where fill light is needed. According to the required light brightness, the third screw 442 is rotated to switch the position of the silver reflective coating 444 or the white reflective coating 445 on the reflective block 441 to achieve reflection of light of different brightness.

[0068] During use, the shading component 5 can also be used to control the light range according to the actual scene requirements. The handle 543 of the reeling member 54 is rotated to drive the winding roller 542 to rotate, and the pull rope 544 is retracted to adjust the height of the counterweight frame 53, so that the shading curtain 52 can be unfolded or retracted to control the light emission angle and range.
