Description

Lamp that facilitates adjustment of lighting position of light source of light emitting device Technical Field

[0001] The present application relates to the technical field of lighting fixtures, and in particular to a lighting fixture that facilitates adjustment of the lighting position of a light source of a light-emitting device. Background Art

[0002] Lamps are a common lighting device in our work and life, and their application environments are diverse. However, for desk lamps used to illuminate the desktop, the "lighting height" and "lighting position" of the light source of the light-emitting device are often adjusted appropriately due to the needs of the lighting environment to better meet the lighting requirements.

[0003] The position adjustment of the light source of the existing lamps is often relatively simple and not flexible enough. For example, when we adjust the height change of the light source of a traditional lamp in the "Z-axis direction" perpendicular to the desktop, it also affects the change of the parallel position of the light source in the "Y-axis direction" parallel to the desktop at the original coordinate point; similarly, when we adjust the parallel position change of the light source in the "Y-axis direction" parallel to the desktop, it also affects the change of the height of the light source in the "Z-axis direction" perpendicular to the desktop at the original coordinate point. That is, the change in one direction cannot be adjusted alone.

[0004] Existing lamp light source position adjustment methods and existing problems:

[0005] Mainly for the spatial movement adjustment method of the lamp light source (i.e.: bidirectional adjustment method of the "Z axis" perpendicular to the desktop and the "Y axis" parallel to the desktop):

[0006] Conventional lighting fixtures currently on the market generally fall into two main types of structural principles for powering their light sources, depending on how the light source is adjusted: 1. Joint-link adjustment of internal wiring (see Chinese patent CN203595029U for details); 2. Memory hose (also known as "gooseneck hose" adjustment, see Chinese patent CN308211313S for details);

[0007] Chinese patent CN203595029U shows the most common "joint connecting rod adjustment structure" currently on the market, which has the following defects: 1. To adjust the spatial position of the light source, it is necessary to adjust the angle and position of multiple joint connecting rods in conjunction with the position adjustment of the light source; this adjustment process is relatively complicated; 2. During the process of adjusting the position and angle of multiple connecting rods, the lamp has corresponding requirements for the space in the environment in which it is located, and more space is required to allow the joint connecting rods to adjust the angle (i.e., it takes up more space); 3. The multi-joint + multi-connecting rod structure leads to instability in the structure and electrical connection of the light source, which is prone to failure;

[0008] Chinese patent CN308211313S shows a lamp with a "gooseneck hose structure" currently on the market, which has the following defects: 1. To adjust the position of the light source in the "Z-axis direction" perpendicular to the tabletop, the light source is also forced to shift in the "Y-axis direction" parallel to the tabletop; similarly, to adjust the position of the light source in the "Y-axis direction" parallel to the tabletop, the light source is also forced to shift in the "Z-axis direction" perpendicular to the tabletop; 2. To adjust the light source to the appropriate angle, the hose shape must be repeatedly bent, which is extremely inconvenient to adjust; 3. The soft and deformable nature of the hose leads to instability of the light source fixed to the hose, which will continue to vibrate elastically when the light source is adjusted.

[0009] Therefore, there is an urgent need for a lamp that is convenient for adjusting the lighting position of the light source of the lighting device to solve the above problems.

[0030] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] Please refer to Figures 1 to 6. The present application provides a lamp 100 that is convenient for adjusting the lighting position of a light source of a light-emitting device. The lamp 100 that is convenient for adjusting the lighting position of a light source of a light-emitting device includes a base 1, a lamp stand 2, a lamp arm 3, a light source 4, and a power supply component 5 for powering the light. The lamp stand 2 is mounted on the base 1, and the length of the lamp arm 3 is adjustable. One end of the lamp arm 3 is slidably mounted on the lamp stand 2 along the Z-axis direction of the base 1, and the other end of the lamp arm 3 is connected to the light source 4. By moving the lamp arm 3 relative to the lamp stand 2, the position of the light source 4 can be adjusted relative to the base 1 along the Z-axis direction of the base 1. (See Figure 1 for the X-axis, Y-axis and Z-axis), by adjusting the length of the lamp arm 3, the position of the light source 4 can be adjusted relative to the base 1 along the Y-axis direction of the base 1. In other words, the adjustment of the length of the lamp arm 3 can achieve the position adjustment of the light source 4 in the Y-axis direction of the base alone, and the sliding of the lamp arm 3 relative to the lamp stand 2 can achieve the position adjustment of the light source 4 in the Z-axis direction of the base alone, so the adjustment can be made in only one direction, which is convenient. Moreover, such a lamp stand structure improves the convenience of adjusting the spatial position of the light source 4 and has the advantage of saving space. Preferably, the base 1 is a clamping clamp or a pedestal base 1, but is not limited to this. Preferably, the light source 4 is detachably connected to the lamp arm 3, specifically, the light source 4 is connected to the lamp arm 3 by magnetic attraction, or the light source 4 is connected to the lamp arm 3 by snap-fitting, or the light source 4 is fixedly connected to the lamp arm 3, but is not limited to this. More specifically, as follows:

[0032] Referring to Figures 3 to 6 , the lamp arm 3 includes a first rod 31 and a second rod 32. The second rod 32 is located below the first rod 31. Both the first rod 31 and the second rod 32 have accommodating cavities. One end of the first rod 31 is slidably mounted on the lamp frame 2 along the Z-axis of the base 1. One end of the second rod 32 is slidably mounted on the first rod 31 along the Y-axis of the base 1. The other end of the second rod 32 is connected to the light source 4. The lamp 100 for facilitating adjustment of the illumination position of the light source of the light-emitting device also includes an arm base 6. The first rod 31 is slidably mounted on the lamp frame 2 via the arm base 6. The lamp frame 2 is provided with a first slide rail 21. The arm base 6 includes a first slider 61 slidably mounted on the first slide rail 21. The first slider 61 is arranged to wrap around the first slide rail 21. A damping assembly (not shown) is provided between the first slide rail 21 and the first slider 61. The damping assembly allows the first slider 61 to be positioned at any position on the first slide rail 21.

[0033] 3 to 6 , the first rod 31 has a second slide rail 311 therein, and the second rod 32 has a second slider 321 slidably mounted on the first rod 31 . The second slider 321 and the second slide rail 311 cooperate with each other to allow the first rod 31 and the second rod 32 to extend and retract relative to each other.

[0034] Referring to Figures 3 to 6 , the lamp 100 for facilitating adjustment of the illumination position of a light source of a lighting device further includes a receiving and deflecting member 7 , which is mounted on the second rod 32 and defines a through-hole 71 for passage of the power supply line 5 of the power supply assembly 5 . The through-hole 71 connects the bottom of the first rod 31 with the bottom of the second rod 32 . As will be appreciated, since the first rod 31 and the second rod 32 are disposed vertically, the receiving and deflecting member 7 is capable of redirecting the power supply line 51 within the first rod 31 and receiving it within the second rod 32 .

[0035] Please refer to Figures 3 to 6. The lamp 100 for facilitating adjustment of the lighting position of the light source of the light-emitting device also includes a rotating shaft 8 and an angle adjustment member 9. The light source 4 is rotatably mounted on the lamp arm 3 via the rotating shaft 8. The angle adjustment member 9 is provided on the rotating shaft 8 to adjust the rotation angle of the light source 4, thereby realizing the angle adjustment of the light source 4.

[0036] Referring to Figures 1 to 5 , the lamp holder 2 is arranged along the Z-axis of the base 1, and the lamp arm 3 is arranged along the Y-axis of the base 1. The lamp 100, which facilitates adjustment of the illumination position of the light source of the light-emitting device, also includes a guide seat 33 disposed on the lamp arm 3. The guide seat 33 defines a guide hole 331 for guiding the power supply line 51 of the power supply assembly 5. Preferably, the light source 4 is a long strip light source 4 and is arranged along the X-axis of the base 1.

[0037] Please refer to Figures 5 to 6. The power supply assembly 5 includes an adjustment assembly and a power supply line 51. The adjustment assembly includes an elastic member 52 and a pulley set 53. One end of the power supply line 51 is connected to the power input terminal. The power input terminal is provided in the base 1. Specifically, one end of the power supply line 51 is connected to the power input terminal in the base 1. The base 1 has a power supply component electrically connected to the power supply line 51. The power supply line 51 is connected to the power supply component. The middle part of the power supply line 51 is wound around the pulley set 53. The other end of the power supply line 51 is connected to the light source 4. The elastic member 52 provides an elastic force. The elastic force causes the power supply line 51 wound around the pulley set 53 to tend to shrink. When the power cord 51 needs to be extended, the light source 4 is pulled to overcome the elastic force of the elastic member 52 so that the power cord 51 can be extended as the position of the light source 4 is adjusted. When the power cord 51 needs to be shortened, the light source 4 is pulled so that the power cord 51 is shortened as the position of the light source 4 is adjusted and the elastic member 52 recovers. The pulley group 53 and the elastic member 52 cooperate with each other so that the power cord 51 can be adaptively adjusted according to the position of the power source and the activity of the lamp holder 2, and the power cord 51 can be selectively extended or retracted. Different from the traditional through-threading mode, it can be adjusted more conveniently and variably in accordance with the adjustment method of the lamp body.

[0038] Referring to Figures 5 and 6 , the power supply assembly 5 also includes a fixed pulley frame 54. The pulley assembly 53 includes a fixed pulley 531, a first movable pulley 532, and a second movable pulley 533. The fixed pulley 531 is mounted on the fixed pulley frame 54. The first movable pulley 532 and the second movable pulley 533 are interconnected. One end of the second movable pulley 533 is connected to the elastic member 52. The middle portion of the power supply line 51 passes between the first movable pulley 532, the second movable pulley 533, and the fixed pulley 531. The fixed pulley 531 of the pulley assembly 53 is slidably mounted within the adjustment frame via the fixed pulley frame 54. The fixed pulley frame 54 moves along the Z-axis of the base 1.

[0039] Referring to Figures 5 and 6 , the power supply assembly 5 also includes a movable pulley frame 55, to which a first movable pulley 532 and a second movable pulley 533 are mounted. The movable pulleys of the pulley assembly 53 are slidably mounted within the adjustment frame via the movable pulley frame 55. The movable pulley frame 55 moves along the Z-axis of the base 1. The first movable pulley 532 and the second movable pulley 533 are fixed side by side to the movable pulley frame 55.

[0040] Please refer to Figures 5 and 6. The fixed pulley frame 54 has a steering column 541. One end of the power supply line 51 is connected to the base 1. The power supply line 51 is sequentially wound around the steering column 541, the lower part of the second movable pulley 533, the upper part of the fixed pulley 531, the lower part of the first movable pulley 532 and finally connected to the light source 4. It can be understood that the manufacturer can adjust the winding method of the power supply line 51 and the specific structure of the pulley group 53 according to actual conditions, so it is not limited to this.

[0041] The adjustment process of the lamp 100 of the present application for facilitating adjustment of the lighting position of the light source of the light emitting device is as follows:

[0042] The length adjustment of the lamp arm 3 can realize the position adjustment of the light source 4 independently in the Y-axis direction of the base, and the sliding of the lamp arm 3 relative to the lamp frame 2 can realize the position adjustment of the light source 4 independently in the Z-axis direction of the base, so adjustment can be performed in only one direction. As the position of the light source 4 is adjusted, the power supply line 51 needs to adaptively adjust its length. When the power supply line 51 needs to be extended, pulling the light source 4 to overcome the elastic force of the elastic part 52 can make the power supply line 51 extend as the position of the light source 4 is adjusted. When the power supply line 51 needs to be shortened, pulling the light source 4 makes the power supply line 51 shortened as the position of the light source 4 is adjusted and the elastic recovery of the elastic part 52.

[0043] By combining the base 1, lamp holder 2 and lamp arm 3 together, the lamp holder 2 is installed on the base 1, and the length of the lamp arm 3 is adjustable. One end of the lamp arm 3 is slidably installed on the lamp holder 2 along the Z-axis direction of the base 1, and the other end of the lamp arm 3 is connected to the light source 4. By moving the lamp arm 3 relative to the lamp holder 2, the position of the light source 4 can be adjusted relative to the base 1 along the Z-axis direction of the base 1, and by adjusting the length of the lamp arm 3, the position of the light source 4 can be adjusted relative to the base 1 along the Y-axis direction of the base. In other words, the length adjustment of the lamp arm 3 can realize the position adjustment of the light source 4 separately in the Y-axis direction of the base, and the sliding of the lamp arm 3 relative to the lamp holder 2 can realize the position adjustment of the light source 4 separately in the Z-axis direction of the base, so that adjustment can be made in only one direction, which is convenient. Moreover, such a lamp holder 2 structure improves the convenience of spatial position adjustment of the light source 4 and has the advantage of saving space.

[0044] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
