Description

Technical Field

[0001] The invention relates to the technical field of desk lamps, and in particular to a desk lamp with adjustable illumination. Background Art

[0002] In modern life, table lamps have become an indispensable lighting tool in homes and offices. However, most table lamp designs on the market still remain in the traditional fixed lighting range, which ignores the user's demand for personalized and flexible lighting. This limitation not only affects lighting efficiency, but may also have an adverse effect on the user's vision health.

[0003] First of all, the waste of light source is a problem that cannot be ignored. Desk lamps with a fixed lighting range often cannot accurately control the distribution of light, causing light to shine on areas that do not need lighting.

[0004] Secondly, glare is also a possible drawback of a fixed illumination range desk lamp. Due to the different positions of users, when the light directly shines into the user's eyes, it will not only cause visual discomfort, but may also cause health problems such as headaches and eye fatigue.

[0005] Furthermore, lack of personalization is another shortcoming of traditional desk lamps. Everyone's height, habits and desktop size are different, but traditional desk lamps cannot provide corresponding adjustment functions to adapt to these differences. This results in users being unable to obtain the lighting experience that best suits them, and whether they are reading, writing or doing delicate work, their efficiency and comfort may be reduced due to uncomfortable light.

[0006] In order to solve these problems, a new type of desk lamp design is urgently needed, which can provide an adjustable lighting range to meet the needs of different users. Summary of the invention

[0007] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a desk lamp with adjustable illumination to solve the problems mentioned in the above background technology section.

[0008] The present invention is achieved through the following technical solutions:

[0009] A desk lamp with adjustable illumination comprises a shell, a heat sink arranged in the shell, a light source plate fixed to the heat sink, a reflector fixed at one end to the heat sink, a positioning paddle extending out of the shell fixed at the other end of the reflector, and the reflector is deformed by moving the positioning paddle.

[0010] Furthermore, one end of the reflector is fixedly connected to the heat sink, and the reflector is deformed by moving the positioning paddle.

[0011] Furthermore, the reflector includes a connecting portion and a reflecting portion arranged in sequence, the connecting portion is fixedly connected to the heat sink, the light source plate is arranged toward the reflecting portion, and the positioning paddle passes through the housing and is connected to the front end of the reflecting portion.

[0012] Furthermore, the heat sink is provided with a slot for the reflector to be embedded in, and the reflector is provided with an inserting plate portion embedded in the slot.

[0013] Furthermore, the slots are provided in a plurality along the height direction.

[0014] Furthermore, a light-transmitting plate is provided in the reflective portion corresponding to the projection area of ​​the housing, and the light from the light source plate is reflected by a reflector to the light-transmitting plate and then passes out.

[0015] Furthermore, the reflector is a thin plate structure.

[0016] Furthermore, it also includes a rotating shaft, a mounting portion is provided between the connecting portion and the reflecting portion, the mounting portion is symmetrically arranged on both sides of the reflecting portion, the rotating shaft passes through the housing and is connected to the mounting portion, and the reflector rotates around the rotating shaft.

[0017] Furthermore, the heat sink is driven to rotate around the rotating shaft by moving the positioning paddle.

[0018] As another embodiment, a desk lamp with adjustable lighting includes a shell, a heat sink fixed in the shell, a light source board fixed above the heat sink, a reflector fixed in the shell, and a knob arranged on the outside of the shell, wherein the knob passes through the shell and is fixedly connected to the heat sink, and the heat sink and the light source board are driven to rotate by the knob.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] Reference Figures 1 to 5 As shown, a desk lamp with adjustable illumination comprises a housing 1, a heat sink 2 disposed in the housing 1, a light source board 4 fixed to the heat sink 2, a reflector 3 fixed to the heat sink 2 at one end, a positioning paddle 5 extending out of the housing 1 fixed to the other end of the reflector 3, and the reflector 3 is deformed by moving the positioning paddle 5. Through the above structure, the desk lamp can adjust the illumination range according to the height of the user and the width of the desktop, improve the lighting effect, protect the user's eyes, improve the utilization rate of light, and achieve the goal of energy saving and emission reduction.

[0030] One end of the reflector 3 is fixed to the heat sink 2, and the reflector 3 is deformed by moving the positioning paddle 5. The light generated by the light source panel 4 will change the angle of emission due to the deformation of the reflector 3, thereby adjusting the light range.

[0031] Reference Figure 3 As shown in the figure, one embodiment of a desk lamp with adjustable illumination of the present invention is shown, and the specific contents of the embodiment are as follows:

[0032] The reflector 3 includes a connecting portion 31 and a reflecting portion 32 arranged in sequence, the connecting portion 31 is fixed to the heat sink 2, the light source panel 4 is arranged toward the reflecting portion 32, and the positioning paddle 5 passes through the housing 1 and is connected to the front end of the reflecting portion 32.

[0033] The reflective portion 32 is provided with a light-transmitting plate 6 corresponding to the projection area of ​​the housing 1 , and the light from the light source panel 4 is reflected by the reflector 3 to the light-transmitting plate 6 and then passes out.

[0034] When in use, the light from the light source panel 4 is emitted toward the reflective portion 32, and then reflected by the reflective portion 32 to the light-transmitting plate 6 and passes through. When the positioning paddle 5 is moved, the connecting portion 31 will be deformed, and finally the reflective portion 32 will be driven to move, thereby changing the angle of light emission and further adjusting the light range.

[0035] The radiator 2 is provided with a slot 21 for the reflector 3 to be embedded in, and the reflector 3 is provided with an insert plate portion 33 embedded in the slot 21. The cooperation between the slot 21 and the insert plate portion 33 facilitates the connection and assembly of the radiator 2 and the reflector 3, wherein the insert plate portion 33 and the connecting portion 31 are arranged vertically, thereby preventing the radiator 2 and the reflector 3 from detaching from each other.

[0036] The slots 21 are provided with a plurality of slots along the height direction. Since the cooperation between each slot 21 and the plug-in plate portion 33 will result in different tensions of the reflector, this difference provides flexibility for adjusting the reflector 3. By simply changing the position of the plug-in plate portion 33, the tension of the reflector can be fine-tuned, thereby adjusting the tightness of the positioning paddle 5. In addition, this design is also helpful in extending the service life of the reflector 3. By accurately controlling the tension, material fatigue caused by excessive stretching or relaxation can be avoided, thereby reducing the loss and maintenance requirements of the reflector 3.

[0037] Reference Figure 4 As shown in the figure, a second embodiment of a desk lamp with adjustable illumination according to the present invention is shown, and the specific contents of the embodiment are as follows:

[0038] The difference between the second embodiment and the first embodiment is that the connection portion 31 is fixedly connected to the rear end surface of the radiator 2. The radiator 2 or the reflector 3 is provided with mutually engaged support points and support holes, and then the reflector 3 is fixed on the radiator 2 through the support points on both sides.

[0039] Reference Figure 2 and Figure 4As shown, in order to accurately limit the deformation amount of the reflector 3 driven by the positioning paddle 5 when it moves, the light-adjustable desk lamp of the second embodiment also includes a rotating shaft 7, and a mounting portion 34 is provided between the connecting portion 31 and the reflecting portion 32, and the mounting portions 34 are symmetrically arranged on both sides of the reflecting portion 32. The rotating shaft 7 passes through the housing 1 and is connected to the mounting portion 34, and the reflector 3 rotates around the rotating shaft 7. The setting of the mounting portion 34 helps to maintain the balance and stability of the reflector 3 when rotating. And through the setting of the mounting portion 34, the deformation of the reflector 3 is mainly generated in the connecting portion 31 during the deformation process, and by limiting the deformation position, the deformation amount of the reflector 3 can be more accurately controlled.

[0040] Reference Figure 5 As shown in the figure, a third embodiment of a desk lamp with adjustable illumination according to the present invention is shown, and the specific contents of the embodiment are as follows:

[0041] In the third embodiment: the radiator 2 is rotatably connected to the housing 1 via a rotating shaft 7, the reflector 3 and the radiator 2 are provided with a slot 21 and a plug-in portion as in the first embodiment, the reflector 3 is provided with a mounting portion 34 as in the second embodiment, the rotating shaft 7 passes through the mounting portion 34 and is connected to the radiator 2.

[0042] When the light range needs to be adjusted, the positioning paddle 5 moves and drives the reflector 3 to deform, and the plug-in part of the reflector 3 drives the heat sink 2 to rotate. The heat sink 2 rotates and drives the light source board 4 to rotate. The light path will change during the rotation of the light source board 4, thereby achieving the adjustment of the light range.

[0043] The advantage of the third embodiment over the first and second embodiments is that the deformation of the connecting portion 31 can be reduced, and material fatigue caused by excessive stretching or relaxation can be avoided, thereby reducing the loss and maintenance requirements of the reflector 3.

[0044] Reference Figure 6 As shown in the figure, a fourth embodiment of a desk lamp with adjustable illumination according to the present invention is shown, and the specific contents of the embodiment are as follows:

[0045] A desk lamp with adjustable illumination comprises a shell 1, a heat sink 2 fixedly arranged in the shell 1, a light source board 4 fixedly arranged above the heat sink 2, a reflector 3 fixedly arranged in the shell 1, and a knob 8 arranged outside the shell 1, wherein the knob 8 passes through the shell 1 and is fixedly connected to the heat sink 2, and the heat sink 2 and the light source board 4 are driven to rotate by the knob 8.

[0046] The reflective portion 32 is provided with a light-transmitting plate 6 corresponding to the projection area of ​​the housing 1 , and the light from the light source panel 4 is reflected by the reflector 3 to the light-transmitting plate 6 and then passes out.

[0047] When the light range needs to be adjusted, the heat sink 2 and the light source board 4 are rotated together by rotating the knob 8, and the reflector 3 remains stationary. The light path will change during the rotation of the light source board 4, and then pass through the light-transmitting plate 6, thereby achieving the adjustment of the light range.

[0048] In summary, the present invention can achieve different light path settings by adjusting the positioning paddle 5 or the knob 8, thereby adjusting the illumination range and illumination intensity. For example, the light can be focused or scattered by changing the position or shape of the reflector 3 to adapt to different user heights and desktop sizes. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes.

[0049] Of course, the structure of the present invention is not only applicable to table lamps, but also to street lamps, mining lamps, high-rise lamps, blackboard lamps, panel lamps, strip lamps, etc., providing more flexible light adjustment functions for these lamps. Users can adjust the light range and intensity of the table lamp according to their needs to improve the efficiency of light utilization.

[0050] In embodiments 1 to 4, the reflector 3 is a thin plate structure, so that it is easy to bend and deform. Specifically, the connecting portion 31, the reflecting portion 32 and the mounting portion 34 are integrally stamped and bent from a metal plate, and the metal is preferably a metal material that is easy to deform, such as aluminum or copper.

[0051] The light source plate 4 of the present invention is arranged at a lower height than the light-transmitting plate 6, that is, the light source is placed at a lower position than the light-emitting surface, so that the light source cannot be seen from the light-emitting surface. This design effectively reduces the glare problem and improves the user's comfort and visual experience.
