TECHNICAL FIELD

[0001] The utility model relates to a desk lamp technical field, specifically to a desk lamp of adjustable illumination. BACKGROUND

[0002] In modern life, desk lamps have become an indispensable lighting tool in homes and offices. However, the design of most desk lamps on the market still remains in the traditional fixed illumination range, which ignores the user's demand for lighting individualization and flexibility. This limitation not only affects the lighting efficiency, but also may adversely affect the user's vision health.

[0003] Firstly, light source waste is a problem that cannot be ignored. Fixed illumination range desk lamps often cannot accurately control the distribution of light, resulting in light shining on areas that do not need illumination.

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

[0005] Furthermore, the lack of individualization is another flaw 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 most suitable lighting experience for themselves, whether reading, writing or performing delicate work, which may reduce efficiency and comfort due to the inappropriateness of the light.

[0033] The reflecting portion 32 is provided with a light-transmitting plate 6 corresponding to the projection area of the shell 1, and the light of the light source plate 4 is reflected to the light-transmitting plate 6 through the reflector 3 and is transmitted out.

[0034] In use, the light of the light source plate 4 is emitted towards the reflecting portion 32, and then is reflected to the light-transmitting plate 6 through the reflecting portion 32 and is transmitted out, when the positioning knob 5 is moved, the connecting portion 31 is deformed, and finally drives the reflecting portion 32 to move, so that the angle of light emission is changed, and then the light range is adjusted.

[0035] The radiator 2 is provided with a slot 21 for embedding the reflector 3, the reflector 3 is provided with a plug-in plate portion 33 embedded in the slot 21, and the connection and assembly of the radiator 2 and the reflector 3 are facilitated through the cooperation of the slot 21 and the plug-in plate portion 33, wherein the plug-in plate portion 33 and the connecting portion 31 are vertically arranged, so as to prevent the radiator 2 and the reflector 3 from being separated from each other.

[0036] The slot 21 is provided with a plurality of slots along the height direction, and the tightness of the reflecting plate is different due to the cooperation of each slot 21 and the plug-in plate portion 33, and the difference provides flexibility for adjusting the reflector 3, and the tightness of the reflecting plate can be fine-tuned by changing the position of the plug-in plate portion 33, so as to adjust the tightness of the positioning knob 5. Moreover, this design is also helpful to prolong the service life of the reflector 3, and the material fatigue caused by excessive stretching or relaxation can be avoided by accurately controlling the tightness, so as to reduce the loss and maintenance demand of the reflector 3.

[0037] Referring to Figure 4 As shown in the figure, the embodiment of the light-adjustable table lamp of the utility model is one of the embodiments, and the specific content is as follows:

[0038] The difference between the second embodiment and the first embodiment is that the connecting portion 31 is fixedly connected to the rear end surface of the radiator 2, wherein the radiator 2 or the reflector 3 is provided with a fulcrum and a supporting hole embedded with each other, and then the reflector 3 is fixed on the radiator 2 through the two fulcrums.

[0039] Referring to Figure 2 and Figure 4As shown, in order to accurately define the deformation amount of the reflector 3 when the positioning dial 5 moves, the light-adjustable desk lamp of the second embodiment further comprises a rotating shaft 7, the connecting portion 31 and the light-reflecting portion 32 are provided with mounting portions 34, the two mounting portions 34 are symmetrically arranged on the two sides of the light-reflecting portion 32, the rotating shaft 7 penetrates the shell 1 and is connected to the mounting portions 34, and the reflector 3 rotates around the rotating shaft 7. The mounting portions 34 are helpful to keep the balance and stability of the reflector 3 when rotating. Moreover, through the mounting portions 34, the deformation of the reflector 3 mainly occurs in the connecting portion 31, and the deformation amount of the reflector 3 can be more accurately controlled by limiting the deformation position.

[0040] Referring to Figure 5 As shown, the figure is the third embodiment of the light-adjustable desk lamp of the utility model, and the specific content of the embodiment is as follows:

[0041] In the third embodiment, the heat sink 2 is rotatably connected to the shell 1 through the rotating shaft 7, the reflector 3 and the heat sink 2 are provided with the slot 21 and the plug-in portion as in the first embodiment, the reflector 3 is provided with the mounting portion 34 as in the second embodiment, the rotating shaft 7 penetrates the mounting portion 34 and is connected to the heat sink 2.

[0042] When the light range needs to be adjusted, the positioning dial 5 moves and drives the reflector 3 to deform, the plug-in portion of the reflector 3 drives the heat sink 2 to rotate, the heat sink 2 drives the light source plate 4 to rotate in the process of rotating, the light path is changed in the process of rotating of the light source plate 4, and then the light range is adjusted.

[0043] The third embodiment has the advantages that the deformation amount of the connecting portion 31 can be reduced, material fatigue caused by excessive stretching or relaxation can be avoided, and the loss and maintenance requirements of the reflector 3 can be reduced.

[0044] Referring to Figure 6 As shown, the figure is the fourth embodiment of the light-adjustable desk lamp of the utility model, and the specific content of the embodiment is as follows:

[0045] A light-adjustable desk lamp comprises a shell 1, a heat sink 2 fixedly arranged in the shell 1, a light source plate 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, the knob 8 penetrates the shell 1 and is fixedly connected to the heat sink 2, and the heat sink 2 and the light source plate 4 are rotated by the knob 8.

[0046] The light-reflecting portion 32 is provided with a light-transmitting plate 6 corresponding to the projection area of the shell 1, and the light of the light source plate 4 is reflected to the light-transmitting plate 6 through the reflector 3 and is transmitted out.

[0047] When it is necessary to adjust the light range, the heat sink 2 and the light source plate 4 are rotated together by rotating the knob 8, and the reflector 3 remains stationary, the light path is changed during the rotation of the light source plate 4, and then the light is transmitted through the light-transmitting plate 6, thereby realizing the adjustment of the light range.

[0048] In summary, the different light path settings can be realized by adjusting the positioning knob 5 or the knob 8, so as to adjust the light range and the light intensity.
