[0031] It should also be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] This utility model embodiment provides an adjustable reading lamp, which includes a lamp board bracket, a knob, a universal joint, and a housing. The universal joint is fitted into the housing, the lamp board bracket is disposed inside the universal joint, the top of the lamp board bracket protrudes from the top of the universal joint, and the knob is disposed on the top of the universal joint and sleeved on the top of the lamp board bracket.
[0033] In one optional implementation of this embodiment, such as Figure 1 As shown, Figure 1 This diagram shows the overall structure of the adjustable reading lamp according to an embodiment of the present invention. The reading lamp includes a lamp plate bracket 1 ( Figure 1 (Not shown in the image) , knob 2, universal head 3 and housing 4, the universal head 3 is fitted into the housing 4, the lamp panel bracket 1 is disposed inside the universal head 3, and the knob 2 is disposed on the top of the universal head 3 and sleeved on the top of the lamp panel bracket 1.
[0034] In one optional implementation of this embodiment, such as Figure 2 and Figure 3 As shown, Figure 2 This diagram illustrates the assembly structure of the lamp panel bracket, knob, and universal joint in an embodiment of the present invention. Figure 3 This diagram shows a first schematic diagram of the lamp panel bracket and knob assembly structure in an embodiment of the present invention. The lamp panel bracket 1 ( Figure 2 Not shown in the image. Figure 3 (As shown in the figure) is located inside the universal head 3, and the knob 2 is located on the top of the universal head 3 and is sleeved on the top of the lamp panel bracket 1.
[0035] In one optional implementation of this embodiment, such as Figure 4 As shown, Figure 4 The first schematic diagram of the lamp panel bracket structure in this embodiment of the present utility model is shown. The outer wall of the lamp panel bracket 1 is provided with a plurality of parallel guide rails 11. The guide rails 11 extend obliquely downward from the top of the outer wall of the lamp panel bracket 1. The guide rails 11 are provided with a plurality of sequentially arranged spherical grooves 12.
[0036] In one optional implementation of this embodiment, the number of guide rails 11 is 1-5.
[0037] Specifically, in this embodiment, the number of guide rails 11 is 3.
[0038] In one optional implementation of this embodiment, any one of the guide rails 11 has the same size.
[0039] In one optional implementation of this embodiment, the number of spherical grooves 12 in any guide rail 11 is 5-20.
[0040] Specifically, in this embodiment, the number of spherical grooves 12 in any one guide rail 11 is 10.
[0041] In one optional implementation of this embodiment, the number and spacing of the spherical grooves 12 in any one guide rail 11 are the same.
[0042] In one optional implementation of this embodiment, such as Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of the knob structure in an embodiment of this utility model is shown. Figure 6 The diagram shows a second schematic of the assembly structure of the lamp panel bracket and the knob in an embodiment of the present invention. The knob 2 is sleeved on the inner wall of the top end of the lamp panel bracket 1 and a guide post 21 is provided. The guide post 21 is embedded in the guide slide rail 11. When the knob 2 is rotated, the guide post 21 can slide in the guide slide rail 11 and be embedded in the spherical groove 12 on the guide slide rail 11 in sequence, thereby driving the lamp panel bracket 1 to move up and down.
[0043] Specifically, the guide post 21 is fitted into the guide rail 11 at the corresponding position and into the spherical groove 12 at the corresponding position. When the knob 2 is rotated, it drives the guide post 21 to move. The guide post 21 slides along the inner wall of the spherical groove 12 and retracts inward. It moves to the next spherical groove 12 through the guide rail 11 between adjacent spherical grooves, expands and engages in the next spherical groove 12. At the same time, since the guide rail 11 is set at an angle, the guide post 21 slides in the guide rail 11 while the knob 2 is fixed to the top of the universal head 3, thus pushing the lamp panel bracket 1 to move up and down.
[0044] Here, a guide rail is set on the outer wall of the lamp panel bracket, and a spherical groove is set inside the guide rail. At the same time, a guide post is set on the inner wall of the knob. The guide post slides in the guide rail and engages with the spherical groove in turn, so as to realize the adjustment level of the reading light knob. It also prevents the illumination range of the reading light from changing due to accidental rotation of the knob, thus achieving a better user experience.
[0045] In one optional implementation of this embodiment, such as Figure 7 As shown, Figure 7 The diagram shows a second schematic of the lamp plate bracket structure in an embodiment of the present invention. A lamp plate 51 is provided on the top of the lamp plate bracket 1. The circumference of the lamp plate 51 is snapped onto the inner wall of the lamp plate bracket 1. Lamp beads 52 are provided on the lamp plate 51.
[0046] In one optional implementation of this embodiment, such as Figure 3 As shown, a through hole 22 is provided in the center of the knob 2, which forms the light emission channel of the lamp bead 52. A lens 53 is covered on the through hole 22, and the lens 53 is located above the lamp plate 51.
[0047] Specifically, the lens is fixed to the through hole of the knob, and the position of the lamp panel and the LEDs on the lamp panel moves up and down as the lamp panel bracket moves. When the lamp panel bracket moves up and down, the distance between the lens and the LEDs changes, and the focal length of the LEDs also changes, thus changing the illumination range of the LEDs. When the lamp panel bracket is at its highest position, the distance between the lens and the LEDs is the shortest, and the illumination range of the LEDs is the widest. When the lamp panel bracket is at its lowest position, the distance between the lens and the LEDs is the longest, and the illumination range of the LEDs is the narrowest. In this way, the light output effect of the reading light can be adjusted by adjusting the knob.
[0048] In one optional implementation of this embodiment, such as Figure 8 As shown, Figure 8 The diagram shows a schematic of the lamp board bracket and control circuit board assembly structure in an embodiment of the present invention. The control circuit board 6 is internally engaged with the universal joint. The control circuit board 6 is annular in shape. The outer circumference of the control circuit board 6 is engaged with the inner wall of the universal joint, and the inner circumference of the control circuit board 6 is engaged with the outer wall of the lamp board bracket 1. The lamp board bracket 1 can move up and down within the inner circle of the control circuit board 6. The control circuit board 6 is electrically connected to the lamp bead 52.
[0049] Specifically, the control circuit board 6 supplies power to the lamp bead 52 and controls the lamp bead 52 to light up.
[0050] In an optional implementation of this embodiment, a Hall sensor 61 is provided on the control circuit board 6.
[0051] In an optional implementation of this embodiment, a magnet groove 62 is provided on the lower half of the outer wall of the lamp panel bracket 1, and a magnet is provided in the magnet groove 62, which is positioned directly above the Hall sensor 61.
[0052] Specifically, the Hall sensor 61 is used to sense the magnetic field of the magnet in the magnetic groove 62. When the guide post of the knob 2 is at the top of the guide rail, the position of the lamp board bracket 1 is at the bottom. At this time, the distance between the Hall sensor 61 and the magnet in the magnetic groove 62 is the closest, and the lamp is not lit. When the knob 2 is rotated, the guide post of the knob 2 moves downward along the guide rail, the distance between the Hall sensor 61 and the magnet in the magnetic groove 62 increases, the Hall sensor 61 senses the change in magnetic field, and generates a light-on signal to control the lamp to light up. When the guide post of the knob 2 returns to the top of the guide rail, the position of the lamp board bracket 1 returns to the bottom, the distance between the Hall sensor 61 and the magnet in the magnetic groove 62 returns to the minimum value, and the lamp is turned off.
[0053] Here, a Hall sensor and magnet are used to replace the switch button, integrating the illumination range and switch control into the knob. This saves space by eliminating the need for an additional switch button, which helps to reduce the size of the reading lamp. Furthermore, the knob allows users to adjust the light illumination range from off to narrow to wide, which aligns with their expectations for reading lamp products and provides a better user experience.
[0054] In one optional implementation of this embodiment, such as Figure 9 As shown, Figure 9 The first schematic diagram of the outer shell structure in an embodiment of the present utility model is shown. The outer shell 4 is provided with a universal head rotation groove 41 that gradually narrows from top to bottom. The universal head 3 is fitted into the universal head rotation groove 41 and can rotate within the universal head rotation groove 41.
[0055] This design incorporates a cooperating structure between the universal head and the universal head rotation slot, allowing the universal head to rotate within the slot and thus adjusting the angle of the reading light output.
[0056] In one optional implementation of this embodiment, such as Figure 3 As shown, the outer circumference of the knob 2 is provided with a number of protrusions 23 that protrude from the inside out, forming a rough rotating surface of the knob.
[0057] Here, raised dots are provided on the outer circumference of the knob to increase the friction on the outer circumference of the knob, making it easier for users to rotate the knob.
[0058] In one optional implementation of this embodiment, such as Figure 10 As shown, Figure 10A second schematic diagram of the housing structure in an embodiment of the present invention is shown. The housing 4 is also provided with an external interface 42, which is electrically connected to the control circuit board 6.
[0059] Specifically, the external interface 42 is used to connect an external power supply and an external signal control component to supply power to the LED beads and input control signals to achieve additional light output effect adjustments, such as color, color temperature, and flashing effects.
[0060] In summary, this utility model embodiment proposes an adjustable reading lamp. A guide rail is provided on the outer wall of the lamp plate bracket, and a spherical groove is provided inside the guide rail. At the same time, a guide post is provided on the inner wall of the knob. The guide post slides in the guide rail and engages with the spherical groove in sequence, realizing the adjustable level of the reading lamp by rotating the knob.
