[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0026] As described in the background section, in modern life, lighting devices not only fulfill the basic function of providing a light source, but also increasingly emphasize the diversity and flexibility of user experience. For example, in various life scenarios such as reading, working, resting, or family gatherings, users often need to adjust the light intensity and direction according to the actual environment and personal preferences to achieve the best lighting effect and visual comfort. Although there are some adjustable brightness lighting products on the market, these products have inconvenience in terms of lighting height.

[0027] To solve this technical problem, this utility model provides a brightness-adjustable lighting device.

[0028] For details, please refer to Figure 1-3 The adjustable brightness lighting device specifically includes:

[0029] A support tube 101 is provided with a first connecting rod 102 on its outer surface. The first connecting rod 102 is connected to a connector, and the connector is connected to an illumination unit. A hand-tightening bolt 111 is provided at the end of the first connecting rod 102 away from the connector. One end of the hand-tightening bolt 111 is inserted into the first connecting rod 102 and contacts the support tube 101.

[0030] The adjustable lighting device provided by this utility model allows for height adjustment of the lighting unit by moving the first connecting rod 102 up and down using a hand-tightening bolt 111. After adjustment, the device is fixed by tightening the hand-tightening bolt 111, thus achieving the lighting height adjustment function. Users can freely adjust the lighting height according to specific needs, which improves the practicality of this application.

[0031] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0034] Example 1, please refer to Figures 1-3 An adjustable brightness lighting device includes a support tube 101. A first connecting rod 102 is sleeved on the outer surface of the support tube 101. The first connecting rod 102 is connected to a connector, and the connector is connected to a lighting unit. A hand-tightening bolt 111 is provided at the end of the first connecting rod 102 away from the connector. One end of the hand-tightening bolt 111 passes through the first connecting rod 102 and contacts the support tube 101. By using the hand-tightening bolt 111, the height of the lighting unit can be adjusted by moving the first connecting rod 102 up and down. After adjustment, it can be fixed by tightening the hand-tightening bolt 111, thereby realizing the lighting height adjustment function. Users can freely adjust the lighting height according to specific needs, which improves the practicality of this application.

[0035] Furthermore, such as Figures 1-2 As shown, a bottom shell 1 is fixedly connected to the bottom end of the support tube 101. The bottom shell 1 is used to support the support tube 101 to improve its stability.

[0036] Example 2 further optimizes the brightness-adjustable lighting device provided in Example 1, specifically, as follows: Figures 1-3 As shown, the connector includes a first connecting plate 103 connected to the first connecting rod 102, a second connecting plate 104 connected to the first connecting plate 103, a second connecting rod 105 connected to one side of the second connecting plate 104, and the second connecting rod 105 connected to the lighting unit. The cooperation of the first connecting rod 102, the first connecting plate 103, the second connecting plate 104 and the second connecting rod 105 enables the support tube 101 to support the lighting unit.

[0037] Furthermore, a fastener is provided between the first connecting plate 103 and the second connecting plate 104. The fastener is used to fasten the first connecting plate 103 and the second connecting plate 104 to achieve fixation after the angle of the lighting unit is adjusted.

[0038] Furthermore, such as Figures 1-3As shown, the fastener includes a fastening bolt 110 connected between the first connecting plate 103 and the second connecting plate 104. One end of the fastening bolt 110 is threaded with a fastening nut 109. The first connecting plate 103 and the second connecting plate 104 can be connected together by the cooperation of the fastening nut 109 and the fastening bolt 110. After tightening the fastening nut 109 and the fastening bolt 110, the first connecting plate 103 and the second connecting plate 104 can be fixed together to achieve the fixation of the angle of the lighting part.

[0039] Example 3 further optimizes the brightness-adjustable lighting device provided in Example 1 or 2, specifically, as follows: Figures 1-3 As shown, the lighting unit includes a lamp housing 106 connected to the second connecting rod 105. A lamp holder is provided inside the lamp housing 106, and a bulb 108 is connected to the lamp holder. The lamp holder and the bulb 108 are connected by a thread to facilitate the replacement of the bulb 108.

[0040] Furthermore, such as Figure 2 As shown, a lampshade 107 is fixedly connected to the bottom of the lamp housing 106, and the bulb 108 is located inside the lampshade 107. The lampshade 107 can protect the bulb 108.

[0041] Furthermore, such as Figure 1 As shown, a brightness regulator 2 is connected to the bottom shell 1. The brightness regulator 2 is connected to the lamp holder and is connected to a power cord. The brightness regulator 2 is used to adjust the lighting brightness of the bulb 108.

[0042] Furthermore, such as Figure 1 As shown, the support tube 101 has a hollow structure. A 3 is provided on the side of the support tube 101 near the lamp cover 107. The 3 is used for the wiring of the connection line between the brightness adjuster 2 and the bulb 108.

[0043] Furthermore, such as Figure 1 As shown, an annular groove 112 is formed around the brightness adjuster 2 on the top of the bottom shell 1. The size of the annular groove 112 is adapted to the size of the lampshade 107, and the position of the annular groove 112 corresponds to the position of the lampshade 107. When the lampshade 107 is lowered to its lowest position, it can be inserted into the annular groove 112. At this time, the lampshade 107 can protect the bulb 108 and the brightness adjuster 2 during the overall transportation. When the lampshade 107 is inserted into the annular groove 112, a safety gap is left between the bulb 108 and the brightness adjuster 2 to prevent the bulb 108 from contacting the brightness adjuster 2.

[0044] The usage process of the adjustable brightness lighting device provided by this utility model is as follows:

[0045] After loosening the hand-tightening bolt 111, push the first connecting rod 102 up and down to adjust the height of the bulb 108. After adjusting, tighten the hand-tightening bolt 111 to fix it. After loosening the fastening bolt 110, rotate the second connecting plate 104 around the fastening bolt 110 to adjust the lighting angle of the bulb 108. After adjusting, tighten the fastening bolt 110 to fix the angle.

[0046] During transport, adjust the angle of the lampshade 107 downwards, loosen the hand-tightening bolt 111, and push the lampshade 107 downwards so that it engages with the annular groove 112. Then tighten the hand-tightening bolt 111. Figure 4 As shown, the lampshade 107 can protect the brightness adjuster 2 and the bulb 108. When using it again, loosen the hand-tightening bolt 111, push the first connecting rod 102 upward to adjust it to the required height, and tighten the hand-tightening bolt 111.
