[0024] The following description of the embodiments of the present invention is provided in conjunction with the accompanying drawings to further describe the specific embodiments of the present invention so that the technical solutions and beneficial effects of the present invention are more clearly understood. The following description of the embodiments with reference to the accompanying drawings is for illustrative purposes only and is intended to explain the present invention, but is not to be construed as limiting the present invention.

[0025] like Figures 1 to 6 As shown, an LED lamp with adjustable illumination angle includes: a lamp housing 1, a lamp holder 2, an LED bulb 3, a telescopic mechanism 4, and an adjustment button 5. The lamp holder 2 is disposed on the lamp housing 1, and the LED bulb 3 is movably disposed on the lamp holder 2. The telescopic mechanism 4 is movably connected to the lamp holder 2, and the adjustment button 5 is connected to the telescopic mechanism 4. The adjustment button 5 is used to control the telescopic mechanism 4 to extend and retract. During the telescopic mechanism 4's extension and retraction, the telescopic mechanism 4 drives the lamp holder 2 to move, thereby controlling the LED bulb 3 to adjust the illumination angle. The user can control the telescopic mechanism 4 to extend or retract using the adjustment button 5. During the extension and retraction process, the telescopic mechanism 4 drives the LED bulb 3 to swing via the lamp holder 2, thereby adjusting the illumination angle of the LED bulb 3.

[0026] In one embodiment, the LED lamp includes a left lamp frame and a right lamp frame of identical structure. The LED bulbs 3 are arranged on the left lamp frame 2. The illumination direction of the LED bulbs 3 is downward or upward. The left lamp frame 2 and the right lamp frame 2 are respectively connected to a telescopic mechanism 4. When the LED lamp is in normal use, the illumination direction of the LED bulbs 3 is vertically upward or vertically downward. When the illumination angle of the LED bulbs 3 is adjusted, the illumination direction of the LED bulbs 3 is deflected to the left or right. In this case, the illumination direction of the LED bulbs 3 is obliquely upward or obliquely downward.

[0027] As one embodiment, the left lamp holder 2 includes a fixing bar 21, a placement ring 22, a sliding bar 23 and a pushing ring 24. The fixing bars 21 are evenly distributed at the upper and lower ends of the lamp housing 1. The placement ring 22 is rotatably arranged between the fixing bars 21 on the same horizontal plane. The sliding bar 23 is movably arranged on the lamp housing 1 and is located between the fixing bars 21 at the upper and lower ends. The pushing ring 24 is respectively arranged at the upper and lower ends of the sliding bar 23 and is cocentric with the placement ring 22. The head of the LED bulb 3 for illumination will be placed in the placement ring 22, and the tail of the LED bulb 3 will be placed in the pushing ring 24. During the movement of the sliding bar 23, the pushing ring 24 located on the sliding bar 23 will push the tail of the LED bulb 3, causing the head of the LED bulb 3 to swing with the placement ring 22 as the support point, thereby adjusting the illumination angle of the LED bulb 3.

[0028] In one embodiment, the lamp housing 1 includes a support column 11, and the telescopic mechanism 4 includes a spring 41, a telescopic arm 42, and a collar 43. The collar 43 and spring 41 are mounted on the support column 11, with the spring 41 positioned between the lamp housing 1 and the collar 43. One end of the telescopic arm 42 is movably connected to the collar 43, and the other end is movably connected to the slide bar 23 of the left or right lamp holder 2. When the collar 43 is moved downward by the adjustment button 5, the telescopic arm 42 expands left and right, causing the slide bars 23 of the left and right holders to move outward. This shifts the illumination direction of the LED bulbs 3 toward the center, thereby illuminating multiple LED bulbs 3 at the same location, increasing the brightness at that location and enabling the user to clearly see objects with the light. When the adjustment button 5 is moved upward, the spring 41 lifts the collar 43, causing the telescopic arm 42 to retract inward, pulling the slide bar 23 inward. This causes the illumination direction of the LED bulbs 3 to spread outward, thereby increasing the illumination range of the LED bulbs 3.

[0029] As one embodiment, the lamp housing 1 includes a base plate 12, a baffle 13 and an outer shell 14, and the base plate 12, the baffle 13 and the outer shell 14 are fixed by screws 15. The left and right sides of the base plate 12 are respectively connected to the left and right sides of the outer shell 14, and the baffle 13 is respectively arranged at the upper and lower ends of the base plate 12. The outer shell 14 has an arc surface 16, and the baffle 13 is provided with a through hole 131.

[0030] In one embodiment, the adjustment button 5 is a rotary knob. One end of the support column 11 is fixedly connected to the base plate 12, and the other end is provided with a thread 111 that mates with the knob. The curved surface 16 of the housing 14 is provided with a circular hole 161 for receiving the knob. The LED lamp adjusts the height of the collar 43 by rotating the knob, allowing precise adjustment of the illumination angle of the LED bulb 3. The adjustment button 5 can also be a retractable key structure of a retractable pen.

[0031] As one embodiment, the upper end 51 of the knob is in the shape of a hexagonal prism, and the lower end 52 is in the shape of a cylinder. The hexagonal prism-shaped end can facilitate the rotation of the knob.

[0032] As one embodiment, two LED bulbs 3 are provided at the upper and lower ends of the left lamp frame. The LED light is provided with multiple LED bulbs 3 to improve the brightness and lighting range.

[0033] The LED lamp described in the present application can drive the telescopic mechanism 4 to perform telescopic movement through the adjustment button 5 to drive the LED bulb 3 located on the lamp holder 2, thereby adjusting the illumination angle of the LED bulb 3, so that multiple LED bulbs 3 illuminate the same position to increase the brightness of the position, allowing users to use the light to see objects clearly; or the LED bulb 3 can be dispersed to extend the range of the indoor lighting effect, thereby improving the lighting function of the LED lamp.

[0034] In the description of the specification, reference to the terms "in one embodiment," "preferably," "example," "specific example," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.
