DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 3As shown, the visual light source device of this embodiment includes a vertical pole 1, and a folding rod 2 is movably connected to the upper end of the vertical pole 1. By vertically moving the folding rod 2, the overall height of the visual light source device can be adjusted. A connecting rod 3 is vertically hinged at one end of the folding rod 2 away from the vertical pole 1. The connecting rod 3, the folding rod 2 and the vertical pole 1 are located in the same vertical plane. By flipping the folding rod 2, the vertical illumination angle of the visual light source device can be changed. A swing rod 4 is horizontally hinged at one end of the connecting rod 3 away from the folding rod 2. The plane where the connecting rod 3 and the folding rod 2 are located is perpendicular to the plane where the vertical pole 1 and the folding rod 2 are located. By flipping the swing rod 4, the lateral illumination angle of the visual light source device can be changed. A lamp holder 5 is installed at one end of the swing rod 4 away from the connecting rod 3, and a lamp 6 is fixed on the lamp holder 5. The illumination direction of the lamp 6 is away from the swing rod 4. Locking mechanisms are provided between the vertical pole 1 and the folding rod 2, between the folding rod 2 and the connecting rod 3, and between the connecting rod 3 and the swing rod 4. When the folding rod 2 moves to a suitable height, the relative position of the vertical rod 1 and the folding rod 2 can be fixed by a locking mechanism; when the connecting rod 3 flips to a suitable vertical angle, the relative position of the folding rod 2 and the connecting rod 3 can be fixed by a locking mechanism; when the swing rod 4 swings to a suitable horizontal angle, the relative position of the connecting rod 3 and the swing rod 4 can also be fixed by a locking mechanism. Based on the above settings and adjustments, the height and angle of illumination can be fixed. The visual light source device disclosed in the present application has the ability to adjust the height and angle of illumination by setting the vertical rod 1 and the folding rod 2 vertically movably connected thereto, the connecting rod 3 vertically hinged to the folding rod 2, and the swing rod 4 laterally hinged to the connecting rod 3, thereby greatly improving the flexibility of the visual light source device.

[0025] In this embodiment, a base 11 is provided at the bottom end of the vertical pole 1, and a connecting hole 111 is formed on the base 11. Specifically, the base 11 is configured as a square plate-like structure, which is perpendicular to the vertical pole 1, and a connecting hole 111 is formed at each of the four corners of the base 11, so that the base 11 can be firmly connected to the external structure by bolts, thereby enhancing the stability of the visual light source device. In addition, four reinforcing plates are provided between the base 11 and the vertical pole 1, and the reinforcing plates are in the shape of a triangle, one of the right-angled sides of which is connected to the base 11, and the other right-angled side is connected to the vertical pole 1. By providing the reinforcing plates, the connection strength between the base 11 and the vertical pole 1 can be greatly improved, thereby further improving the stability of the visual light source device.

[0026] In this embodiment, the folding rod 2 and the vertical rod 1 are formed with a plurality of limit holes 21 arranged at intervals in the vertical direction, and the limit bolts 22 are detachably inserted in the limit holes 21. The vertical rod 1 and the folding rod 2 are both made of hollow square tubes, and the inner diameter of the vertical rod 1 is consistent with the outer diameter of the folding rod 2, so that the folding rod 2 can be inserted into the vertical rod 1 and the vertical rod 1 and the folding rod 2 can be prevented from rotating. In the connecting section of the vertical rod 1 and the folding rod 2, a plurality of limit holes 21 are formed at intervals in the vertical direction, and the limit holes 21 penetrate the opposite side tube walls of the vertical rod 1 and the folding rod 2. The spacing of the limit holes 21 formed on the vertical rod 1 is the same as the spacing of the limit holes 21 formed on the folding rod 2, so as to allow the limit bolts 22 to be inserted. In other embodiments, the limit bolts 22 can also be replaced with other forms, such as pins, which are not specifically limited here.

[0027] In this embodiment, the folding rod 2 includes a horizontal rod section 23 and a vertical rod section 24 connected end to end. The end of the horizontal rod section 23 away from the vertical rod section 24 is hinged to the connecting rod 3, and the end of the vertical rod section 24 away from the horizontal rod section 23 is movably connected to the vertical rod 1. The horizontal rod section 23 and the vertical rod section 24 constituting the folding rod 2 are perpendicular to each other. The end of the horizontal rod section 24 away from the vertical rod section 24 is penetrated by a shaft, and the hinge seat formed at the end of the connecting rod 3 is connected to the shaft. Further, the connecting rod 3 is hinged with a strip-shaped inclined plate 31, and the inclined plate 31 is formed with a long hole 311 along its length direction. The locking bolt 25 threaded on the horizontal rod section 23 is inserted into the long hole 311. The folding rod 2 and the connecting rod 3 are both made of square tubes. A thread hole is formed on one side wall of the folding rod 2. A locking bolt 25 is installed in the thread hole. A diagonal plate 31 is hinged on the same side wall of the connecting rod 3. The diagonal plate 31 is set as a strip plate. A long hole 311 is formed along its length direction near one end of the folding rod 2. The locking bolt 25 penetrates the long hole 311. By screwing the locking bolt 25, the diagonal plate 31 will be clamped, so that the relative position of the folding rod 2 and the connecting rod 3 is fixed. More specifically, according to actual needs, the angle range between the cross bar section 23 and the connecting rod 3 is set to 75°-145°.

[0028] Furthermore, a shaft is passed through the end of the connecting rod 3 away from the folding rod 2, and the hinge seat formed at the end of the swing rod 4 is connected to the shaft. A limit plate 32 is fixed on the connecting rod 3, and an arc-shaped waist hole 321 is formed on the limit plate 32, and a locking bolt 322 threaded on the swing rod 4 is inserted into it. By screwing the locking bolt 322, the limit plate 32 will be clamped, so that the relative position of the connecting rod 3 and the swing rod 4 is fixed. More specifically, according to actual needs, the angle range between the swing rod 4 and the connecting rod 3 is set to 150°-180°.

[0029] In this embodiment, a mounting plate 41 is formed at one end of the swing rod 4 away from the connecting rod 3. The mounting plate 41 is perpendicular to the swing rod 4 and is formed with a plurality of waist-shaped holes 42 arranged in a ring. The fastening bolts 43 correspondingly arranged on the lamp holder 5 are inserted into the waist-shaped holes 42. The mounting plate 41 is configured as a circular plate-like structure. There are four waist-shaped holes 42 formed on the mounting plate 41, which are evenly distributed along the circumference of the mounting plate 41. Four fastening bolts 43 are correspondingly threaded on the lamp holder 5. Each fastening bolt 43 is inserted into a waist-shaped hole 42. The lamp holder 5 can rotate relative to the swing rod 4 within the length range of the waist-shaped hole 42, thereby adding another dimension of light adjustment. Specifically, the rotation angle of the lamp holder 5 around the swing rod 4 is 0°-50°. By screwing and locking the fastening bolts 43, the mounting plate 41 will be clamped, so that the relative position of the swing rod 4 and the lamp holder 5 is fixed.

[0030] In this embodiment, the lamp holder 5 includes an annular wall plate 51, on which a plurality of screws 511 are provided. The lamp 6 is located in the space enclosed by the wall plate 51 and is squeezed from the side by the screws 511. The wall plate 51 encloses three annular frames, each of which is equipped with a lamp 6. The user can use different lamps 6 according to actual needs. The wall plate 51 is provided with screws 511, which squeeze the side wall of the lamp 6 from the side, so that the lamp 6 is connected to the lamp holder 5. Since the front side of the lamp 6 is not blocked, the lighting is not affected; at the same time, since the back side of the lamp 6 is not wrapped by the lamp holder 5, the heat dissipation efficiency can be improved.
