[0003] The current light therapy lamp generally adopts a single lamp head structure. In order to achieve good light therapy effect and reach the required 10000 lux illumination of strong light treatment, a large current drive must be used to achieve sufficient power. However, under the drive of a large current, the light-emitting chip will generate a large amount of heat. The lamp must use a forced cooling method to prevent the chip from being damaged due to overheating. The efficiency of the forced cooler will gradually decrease with the increase of the use time, affecting the overall performance of the lamp and shortening the service life of the light source. At the same time, in order to improve the central light intensity, the existing light therapy lamp adopts a light guide cylinder and a heat-resistant glass lens for light condensation. The generated light area will form a clear and high-contrast boundary, making the generated light source not soft and natural. In addition, the combination of the forced cooler and the light guide cylinder will make the lamp size high and the gravity center high, affecting the stability of the lamp installation and use. In addition, the single lamp head lamp needs to ensure sufficient light range, so the lamp head usually needs to be designed large enough, so that the overall quality of the lamp is concentrated, and there is a risk of sinking or deformation after installation.

DETAILED DESCRIPTION
[0030] The present invention will now be described in detail with reference to the accompanying drawings.
[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] The light therapy lamp includes at least multiple lamp heads, a magnetic mounting bracket rear cover 7 for mounting the lamp heads, and a magnetic mounting bracket front cover 9 primarily used to shield the mounting area of the magnetic mounting bracket rear cover 7. For example... Figure 1 As shown, this embodiment of the application uses a lamp with four sets of lamp heads as an example for illustration. Obviously, in some application scenarios, it is also feasible for the light therapy lamp with this structure to include only one set of lamp heads. Each set of lamp heads is respectively installed at the corresponding through hole on the rear cover 7 of the magnetic mounting bracket, and the front cover 9 of the magnetic mounting bracket is connected to the rear cover 7 of the magnetic mounting bracket by magnetic attraction. Magnetic attraction means that a magnet 74 is installed on one of them, or one is made of ferromagnetic material and the other is a magnetic conductor that can be attracted by the magnet 74. For example, a magnet 74 can be installed on the rear cover 7 of the magnetic mounting bracket, and the front cover 9 of the magnetic mounting bracket can be made of iron.
[0033] like Figure 1 As shown, the four lamp heads are arranged in an array on the back cover 7 of the magnetic mounting bracket, which ensures the uniformity of light emission and the effectiveness of light therapy.
[0034] In some embodiments, the lamp body mounting structure mounts the lamp body onto the magnetic mounting bracket rear cover 7 by penetrating the magnetic mounting bracket rear cover 7. As one possible implementation, such as... Figure 2 As shown, the lamp body mounting structure includes a front-end fixing ring 8 and a rear-end fixing ring 6. The lamp body is fixed on the rear-end fixing ring 6. The rear-end fixing ring 6 is installed on the corresponding through hole on the magnetic mounting bracket rear cover 7 through the front-end fixing ring 8. The front-end fixing ring 8 and the rear-end fixing ring 6 are located on both sides of the magnetic mounting bracket rear cover 7. After the two are connected, the lamp body is installed on the magnetic mounting bracket rear cover 7.
[0035] In this embodiment of the application, the lamp body is fixed to the rear end fixing ring 6 of the lamp body by the heat dissipation structure 2.
[0036] like Figure 3As shown in the structural diagram of the heat dissipation structure 2 in one embodiment, the heat dissipation structure 2 is integrally formed by die casting (or composed of several parts). The bottom end 20 of the heat dissipation structure 2 is provided with a receiving cavity 22, and the bottom end 20 of the heat dissipation structure 2 is connected to the rear end fixing ring 6 of the lamp body, and the lamp body is arranged in the receiving cavity 22 of the bottom end 20 of the heat dissipation structure 2. As a feasible way, the bottom end 20 of the heat dissipation structure 2 is connected to the rear end fixing ring 6 of the lamp body by screwing, for example, the bottom end 20 of the heat dissipation structure 2 is provided with external threads, and the end of the rear end fixing ring 6 of the lamp body close to the lamp body is provided with internal threads, and the heat dissipation structure 2 is connected to the rear end fixing ring 6 of the lamp body by the threads at the bottom end.
[0037] As a preferred embodiment, as shown in Figure 3 The heat dissipation structure 2 is arranged in a fishbone pattern in the circumferential direction, thereby significantly increasing the heat dissipation area and ensuring good heat dissipation performance of the lamp body.
[0038] In addition, in some embodiments, the heat dissipation structure 2 is provided with at least one set of wire grooves 21 in the axial direction, and the wire cable for supplying power to the lamp body can be arranged in the wire groove 21, thereby avoiding potential risks caused by the disordered wire cable. In addition, the wire groove 21 can also serve as a mounting part of the lamp body on the heat dissipation structure 2.
[0039] In some feasible embodiments, a plurality of sets of wire grooves 21 are arranged in the axial direction of the heat dissipation structure 2, and the wire groove 21 is a longitudinal U-shaped groove, which on the one hand serves as a wire groove 21 to guide the wire cable connected to the lamp body, and on the other hand can be used as a screw hole for mounting the lamp body.
[0040] In addition, at the end opposite to the lamp body, i.e. the top end of the heat dissipation structure 2, a wire cable fixing seat 1 is connected in some embodiments. As shown in Figure 4 The wire cable fixing seat 1 is provided with first screw holes 10 at both ends and a wire pressing groove 11 in the middle of the bottom surface. The wire cable fixing seat 1 can be connected to the top end of the heat dissipation structure 2 through the first screw holes, for example, the wire groove 21 in the previous embodiment can be used as a screw hole for mounting the wire cable fixing seat 1. The wire pressing groove 11 is used to press the wire cable connected to the lamp body, and plays a role in fixing the wire cable and preventing interference between the wire cables.
[0041] The lamp body as a light emitting device includes the LED chip 3 in some embodiments. In order to improve the light efficiency and make the optical fibers uniformly distributed, the lamp body further includes a reflective light cup 4 which can also control the light beam angle. In addition, in order to protect the LED chip 3, the lamp body further includes a glass light transmission sheet 5 which can isolate external dust, moisture and the like, prevent these substances from directly contacting the LED chip 3, and protect the light source. On the other hand, the glass light transmission sheet 5 can also filter and scatter light, making the light more uniform and soft, and reducing glare. The LED chip 3, the reflective light cup 4 and the glass light transmission sheet 5 are sequentially arranged from the heat dissipation structure 2 to the rear end fixing ring 6 of the lamp body.
[0042] As shown in Figure 5 , a plurality of mounting holes 30 are arranged on the LED chip 3, and the LED chip 3 can be connected to the heat dissipation structure 2 by passing screws or the like through the mounting holes 30. For example, after the screws pass through the mounting holes 30, they are connected to the position of the wire groove 21 at the bottom end 20 of the heat dissipation structure in the above embodiment.
[0043] The front end fixing ring 8 and the rear end fixing ring 6 of the lamp body are preferably in the form of a circular tube. As shown in Figure 6 , in some embodiments, a first flange 80 is arranged on the outer wall of the front end fixing ring 8 of the lamp body. The first flange 80 can be arranged at the middle or bottom of the front end fixing ring 8 of the lamp body. The first flange 80 divides the front end fixing ring 8 of the lamp body into an upper half 81 and a lower half 82 (if the first flange 80 is located at the bottom of the front end fixing ring 8 of the lamp body, there is no lower half 82). The upper half 81 of the front end fixing ring 8 is limited by the first flange 80 after passing through the through hole of the rear cover 7 of the magnetic mounting bracket, so that the front end fixing ring 8 of the lamp body cannot pass through the rear cover 7 of the magnetic mounting bracket. Obviously, if the first flange 80 is in the form of a circular ring, its inner diameter is larger than the diameter of the through hole of the rear cover 7 of the magnetic mounting bracket. The upper half 81 of the front end fixing ring 8 passing through the rear cover 7 of the magnetic mounting bracket extends into the rear end fixing ring 6 of the lamp body to achieve connection. The so-called extension refers to the inner wall of the upper half 81 of the front end fixing ring 8 surrounding the rear end fixing ring of the lamp, or the outer wall of the upper half 81 of the front end fixing ring 8 being surrounded by the rear end fixing ring of the lamp. Taking the threaded connection between the front end fixing ring 8 of the lamp body and the rear end fixing ring of the lamp as an example, it refers to the outer thread of the upper half 81 of the front end fixing ring 8 being connected with the inner thread of the bottom end of the rear end fixing ring of the lamp, or the inner thread of the upper half 81 of the front end fixing ring 8 being connected with the outer thread of the bottom end of the rear end fixing ring of the lamp.
[0044] In some embodiments, a second flange 60 is arranged on the inner wall or the outer wall (middle part) of the rear end fixing ring 6 of the lamp body, which limits the length of the front end fixing ring 8 of the lamp body extending into the rear end fixing ring 6 of the lamp body. The second flange 60 divides the rear end fixing ring 6 into an upper half 61 of the rear end fixing ring and a lower half 62 of the rear end fixing ring. If the inner wall of the upper half 81 of the front end fixing ring surrounds the lower half, the second flange 60 is arranged on the outer wall of the rear end fixing ring 6, otherwise, if the outer wall of the upper half 81 of the front end fixing ring is surrounded by the lower half 62 of the rear end fixing ring, the second flange 60 is arranged on the inner wall of the rear end fixing ring 6. As a preferred embodiment, as shown in Figure 7 , the second flange 60 is arranged on the inner wall of the rear end fixing ring 6 of the lamp body, so that the second flange 60 not only limits the depth of the front end fixing ring 8 of the lamp body rotating in, but also the upper half 61 of the rear end fixing ring formed can carry the glass light transmission sheet 5 and the reflective light cup 4 of the lamp body.
[0045] In order to improve the safety of the light therapy lamp, in some embodiments, a first anti-falling rope 75 is connected to the rear cover 7 of the magnetic mounting bracket or at least one set of lamp holder, which is fixed to the ceiling joist 77 when the lamp is installed to prevent the lamp from falling off. In some feasible embodiments, the first anti-falling rope 75 can be connected to the cable fixing seat 1 in the foregoing embodiments, that is, when the cable fixing seat 1 is installed on the heat dissipation structure 2 by screws, the first anti-falling rope 75 is connected to one of the screws.
[0046] For the embodiment of connecting the first anti-falling rope 75 to the rear cover 7 of the magnetic mounting bracket, as shown in Figure 8 , a plurality of groove cross bar structures are arranged on the rear cover 7 of the magnetic mounting bracket, which are composed of connecting parts 70 at both ends and cross bars on the left and right sides between the two ends, and the first anti-falling rope 75 can be connected to one of the connecting parts 70, and the cross bars can also serve as reinforcing ribs of the rear cover 7 of the magnetic mounting bracket to improve its rigidity and prevent structural deformation.
[0047] As shown in Figure 8 , a plurality of screw through holes 71 for installation are arranged circumferentially on the rear cover 7 of the magnetic mounting bracket, distributed around the rear cover 7 of the magnetic mounting bracket. A plurality of magnets 74 are installed on the rear cover 7 of the magnetic mounting bracket by cross screws 72, also distributed around the rear cover 7 of the magnetic mounting bracket, and the plurality of magnets 74 are used to attract the front cover 9 of the magnetic mounting bracket.
[0048] In addition, in some embodiments, a second anti-falling rope 76 is connected between the rear cover 7 of the magnetic mounting bracket and the front cover 9 of the magnetic mounting bracket. At least one connecting hole 73 is arranged on the rear cover 7 of the magnetic mounting bracket to support the second anti-falling rope 76 to pass through.
[0049] The front cover 9 of the magnetic mounting bracket is in a frame shape. Figure 9 As shown in the figure, at least one vertical through hole structure 90 is arranged on the front cover 9 of the magnetic mounting bracket, and is used for connecting the second anti-falling rope 76.
[0050] As shown in the figure, at least one vertical through hole structure 90 is arranged on the front cover 9 of the magnetic mounting bracket, and is used for connecting the second anti-falling rope 76. Figure 10 As shown in the figure, at least one vertical through hole structure 90 is arranged on the front cover 9 of the magnetic mounting bracket, and is used for connecting the second anti-falling rope 76.
[0051] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
