[0002] Lighting fixtures are devices used for illumination, designed to convert electrical energy into light energy to achieve the function of lighting. These devices typically include one or more light sources (such as light bulbs, LEDs, etc.), as well as the circuitry and control components necessary to supply electrical energy to the light sources. Besides the light source component;

[0003] In the existing technology, fixing the lamps is inconvenient, the installation is complicated, and the operation is difficult, which is not conducive to the use of the user.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN211146181U) discloses a lighting fixture including a lamp post, a lamp head, and a self-locking device. The self-locking device includes a housing, an adjustment button, an elastic element, and a steel ball. The housing includes a control groove whose cross-sectional area gradually increases from a first end to a second end. The adjustment button slides within the first end of the housing, with its first end located within the control groove. The adjustment button has a second through hole for mounting the lamp post. The steel ball is mounted on the first end of the adjustment button, abutting against the lamp post. The control groove compresses the steel ball, allowing it to move radially relative to the adjustment button to control the compressive force between the steel ball and the lamp post. The elastic element gives the adjustment button a tendency to move towards the first end of the housing. This lighting fixture allows for lamp head height adjustment simply by pressing the adjustment button; releasing it creates a self-locking mechanism for fixation. The structure is simple, and operation is straightforward.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist during their operation. For example, the light from the lamps is too bright and can easily cause dizziness, affecting user comfort. Utility Model Content

[0006] The purpose of this invention is to provide a lamp that uses diffuse reflection lighting to solve the problem mentioned in the background art that the light from the lamp is too bright and can easily cause dizziness for users, thus affecting their comfort.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a lamp that provides illumination through diffuse reflection, comprising a main body and a power supply fixedly installed on the right side of the main body, and the power supply having a power cover at its upper end;

[0008] End caps are bolted to the left and right sides of the main body, and small cover plates are bolted to the outer side of the end caps. A light-emitting module is provided at the lower end of the main body, and the upper end of the light-emitting module is correspondingly provided to the inner wall of the main body.

[0009] The bottom of the end cap is provided with a second airbag, and the upper end of the second airbag is provided with a stabilizing support component, which presses against the light-emitting module through the expansion of the second airbag.

[0010] Furthermore, the main body is arc-shaped, has a light-transmitting design, and is made of PMMA light guide plate.

[0011] Furthermore, the lower outer end of the end cap is curved, and an installation groove is provided inside the lower end of the end cap.

[0012] Furthermore, a baffle is fixedly installed on the lower inner side of the small cover plate, and the baffle is correspondingly set with the mounting groove, and the left and right ends of the light-emitting module are located between the mounting groove and the baffle.

[0013] Furthermore, the stabilizing support assembly includes a first airbag fixedly installed on the outside of the end cap, and the first airbag and the second airbag are connected by an air duct.

[0014] Furthermore, both the first and second airbags are elastically configured, and the outer side of the first airbag and the front and rear edges of the small cover plate are press-fitted together.

[0015] Furthermore, the second airbag is located inside the mounting groove, and the second airbag corresponds to the lower left and right sides of the light-emitting module.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The light fixture illuminates the interior of the main body through the light-emitting module, producing uniform light and avoiding bright spots or shadows, thus improving visual comfort. When the light source of the light-emitting module illuminates the interior of the main body, some of the light is emitted from the back of the main body and illuminates through the diffuse reflection of the chassis, resulting in soft light, reducing glare, and illuminating the ceiling.

[0018] Furthermore, the PMMA light guide plate, the main body material, has excellent optical properties, which can effectively conduct and scatter light, improve the utilization rate of the light source, and the brightness and color temperature of the lamp can be adjusted by the switch on the power supply to meet various user scenarios and improve the adaptability of the device.

[0019] Furthermore, during use, the end caps on both sides are bolted to the left and right ends of the main body. After the light-emitting module is inserted into the mounting groove of the end cap, it can be blocked and limited above the left and right ends of the light-emitting module, making it easy to install lighting fixtures. The power supply can be turned on through the power cover for operation, which is simple and convenient.

[0020] 2. When installing the light-emitting module, first install it inside the mounting groove of the end cover. At this time, as the bolts of the small cover are installed, the small cover squeezes the first airbag, so that the upper end of the light-emitting module abuts against the baffle for stable installation, improving the stability of the device and preventing the internal light-emitting module from falling off due to shaking of the device.

[0028] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1-4The technical solution shown discloses the following to solve the problem of glare from conventional lamps: a main body 1 and a power supply 2 fixedly installed on the right side of the main body 1, with a power supply cover 3 at the upper end of the power supply 2; end caps 4 are bolted to the left and right sides of the main body 1, and small cover plates 5 are bolted to the outer side of the end caps 4; a light-emitting module 6 is provided at the lower end of the main body 1, with the upper end of the light-emitting module 6 corresponding to the inner wall of the main body 1; the main body 1 is arc-shaped and light-transmitting, and is made of PMMA light guide plate; the lower outer end of the end caps 4 is curved, and an installation groove 7 is provided inside the lower end of the end caps 4; a baffle 8 is fixedly installed on the lower inner side of the small cover plate 5, and the baffle 8 corresponds to the installation groove 7; and the left and right ends of the light-emitting module 6 are located between the installation groove 7 and the baffle 8.

[0031] In this embodiment, the light fixture emits light through the light-emitting module 6, which illuminates the interior of the main body 1. The light output is uniform, avoiding bright spots or shadows, thus improving visual comfort. When the light source of the light-emitting module 6 illuminates the interior of the main body 1, some of the light is emitted from the back of the main body 1 and illuminates the interior through diffuse reflection from the chassis. The light output is soft, reducing glare and illuminating the ceiling. The PMMA light guide plate material of the main body 1 has excellent optical properties, which can effectively conduct and scatter light, improving the utilization rate of the light source. The device can adjust the brightness and color temperature of the light fixture through the switch on the power supply 2 to meet various user scenarios and improve the adaptability of the device. In use, the end caps 4 on the left and right sides are installed on the left and right ends of the main body 1 with bolts. Then, the left and right ends of the light-emitting module 6 are inserted along the mounting grooves 7 of the end caps 4, and the small cover plate 5 is installed with bolts. The baffle 8 inside the small cover plate 5 can block and limit the light-emitting module 6 above the left and right ends, making it easy to install the lighting fixture. The power supply 2 can be opened through the power cover 3 for operation, which is simple and convenient.

[0032] Example 2:

[0033] like Figure 3 , Figure 5 and Figure 6 The technical solution shown discloses the following to solve the problem of poor stability of the lamp after installation: a second airbag 11 is provided at the bottom of the end cover 4, and a stabilizing support component is provided at the upper end of the second airbag 11. The stabilizing support component is expanded by the second airbag 11 to abut against the light-emitting module 6. The stabilizing support component includes a first airbag 9 fixedly installed on the outside of the end cover 4, and the first airbag 9 and the second airbag 11 are connected by a duct 10. Both the first airbag 9 and the second airbag 11 are elastically set, and the outer side of the first airbag 9 and the front and rear edges of the small cover plate 5 are corresponding to form a pressing structure. The second airbag 11 is located inside the mounting groove 7, and the second airbag 11 corresponds to the lower ends of the left and right sides of the light-emitting module 6.

[0034] In this embodiment, when the light-emitting module 6 is installed, it is first installed inside the mounting groove 7 of the end cover 4. At this time, as the small cover plate 5 is bolted on, the small cover plate 5 squeezes the first airbag 9. After the first airbag 9 is squeezed, the gas inside is transported to the second airbag 11 through the air guide tube 10. After the second airbag 11 expands at the bottom of the light-emitting module 6, it supports the left and right ends of the light-emitting module 6. Therefore, the upper end of the light-emitting module 6 is pressed against the baffle 8 for stable installation, which improves the stability of the device and prevents the light-emitting module 6 from falling off due to shaking of the device.
