[0016] The exemplary embodiments will be described in detail herein below with reference to the drawings. The following description is merely exemplary in nature and is not intended to limit the present application or the application and uses of the present application. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding background of the application or the following detailed description.

[0017] Example 1:

[0018] Grain silos are typically located in enclosed, high-dust environments, requiring lighting systems to meet stringent safety standards to prevent any potential fire or explosion risks. Explosion-proof lamps are commonly used in grain silos. Their main working principle involves using specialized structural design and material selection to ensure that the internal electrical components are isolated from external flammable gases or dust, thus preventing electrical sparks from igniting surrounding combustible materials. Chinese utility model patent application number 202122319519.4 discloses a fumigation-proof and explosion-proof lamp for grain warehouses. While this patent enhances internal sealing by using a sealing gasket between the lampshade and the outer shell, the small light-transmitting area of ​​the lampshade results in a limited illumination range, and uneven stress on the sealing gasket can easily lead to a decrease in airtightness.

[0019] To address the problem of limited illumination range in existing technologies, this invention provides an explosion-proof lighting fixture for grain storage that can effectively improve the illumination range of the fixture.

[0020] like Figure 1 As shown:

[0021] This utility model provides an explosion-proof lighting fixture for grain storage, comprising a lighting component, a first reflector 21, and a second reflector 22. The lighting component has a light-emitting end at its bottom. The first reflector 21 is located below the lighting component, and its reflective surface corresponds to the light-emitting end of the lighting component. The second reflector 22 is located on the side of the lighting component, and its reflective surface corresponds to the reflective surface of the first reflector 21. The first reflector 21 reflects the light emitted by the lighting component to the second reflector 22, and the second reflector 22 reflects the light reflected by the first reflector 21 towards the area requiring illumination. The lighting component is connected to a circuit and provides lighting functionality. Due to sealing requirements, the light-transmitting area of ​​the lighting component is small, resulting in a small lighting range. To increase the lighting range, a first reflector 21 is positioned directly opposite the light-emitting end below the lighting component. A second reflector 22 is then positioned on the top side of the lighting component. Since typical lighting fixtures are mounted on the ceiling, the second reflector 22 is also mounted on the ceiling to maximize the lighting range. The light-emitting end of the lighting component emits light, which travels downwards to the first reflector 21. The light is then reflected diagonally upwards from the first reflector 21 to the second reflector 22. Upon reaching the second reflector 22, the light is reflected onto the ground or other areas inside the storage space. Through these two reflections, the light-emitting area with a smaller lighting range is reflected, expanding the angle of light illumination and thus achieving the effect of expanding the lighting range.

[0022] In one preferred embodiment of the present application, the lighting assembly comprises a lamp box 11, a lamp tube 12 and a lamp shade 13, the lamp box 11 is provided with a mounting groove at the bottom, wherein: the lamp tube 12 is arranged inside the lamp box 11; the mounting groove is arranged along the axial direction of the lamp tube 12; the lamp shade 13 is mounted in the mounting groove; the first reflecting plate 21 is arranged below the lamp shade 13; and the second reflecting plate 22 is arranged at the side of the lamp box 11. The lamp box 11 is fixedly installed on the ceiling of a house, the mounting groove at the bottom of the lamp box 11 is used for mounting the lamp shade 13, and sealing glue should be applied between the lamp shade 13 and the mounting groove during installation to ensure the sealing of the inside of the lamp box 11 and prevent external dust or harmful gas from entering the lamp box 11. The lamp box 11 is preferably square in shape, and the outer contour of the mounting groove should avoid irregular shapes such as curves, so the preferred shape of the mounting groove and the lamp shade 13 should both be rectangular to avoid uneven stress after installation, which can cause a decrease in sealing performance.

[0023] In one preferred embodiment of the present application, the explosion-proof lamp further comprises a third reflecting plate 23, and the second reflecting plate 22 and the third reflecting plate 23 are symmetrically arranged on the lamp box 11 on both sides of the axial direction of the lamp tube 12. The second reflecting plate 22 and the third reflecting plate 23 are arranged on both sides of the lamp box 11 to maximize the reflection range and thus expand the lighting range.

[0024] In one preferred embodiment of the present application, the lamp shade 13 is a convex lens, the first reflecting plate 21 is a convex mirror, the second reflecting plate 22 is a concave mirror, and the third reflecting plate 23 is a concave mirror. When the light emitted by the lamp tube 12 passes through the lamp shade 13, the light is refracted due to the convex lens of the lamp shade 13, causing the light passing through the lamp shade 13 to diffuse. The diffused light is further diffused by the convex mirror of the first reflecting plate 21 and is reflected to the obliquely upward of both sides of the first reflecting plate 21, and then reaches the second reflecting plate 22 and the third reflecting plate 23. Since the light is obliquely reflected on the second reflecting plate 22 and the third reflecting plate 23 at this time, the second reflecting plate 22 and the third reflecting plate 23 are set as concave mirrors to reflect as much light as possible. Thus, the light emitted by the lamp tube 12 can be diffused and irradiated inside the house.

[0025] In one preferred embodiment of the present application, the explosion-proof lamp further comprises a light guide ring 31, the light inlet section of the light guide ring 31 passes through the lamp box 11 along the axis of the lamp tube 12, and the light outlet section of the light guide ring 31 is arranged below the first reflecting plate 21. Since the first reflecting plate 21 is arranged below the lamp tube 12, the reflected light expands the illumination range, but there is an illumination dead angle below the first reflecting plate 21. Therefore, the light guide ring 31 is arranged. The light guide ring 31 is made of transparent plastic or glass, and its main function is to conduct the light emitted by the light source along its length direction and uniformly distribute the light at the required position. A part of the light inlet section of the light guide ring 31 is arranged in the lamp box 11, part of the light emitted by the lamp tube 12 enters the light guide ring 31 and is conducted along the light guide ring 31 to the light outlet section of the light guide ring 31, which is arranged below the first reflecting plate 21. Therefore, the light emitted by the light outlet section of the light guide ring 31 can illuminate the dead angle below the first reflecting plate 21, further improving the illumination range.

[0026] In one preferred embodiment of the present application, the lamp box 11 is provided with a light guide hole, the light guide ring 31 enters the lamp box 11 through the light guide hole, and a sealing sleeve 32 is arranged between the light guide hole and the light guide ring 31. Since the light guide ring 31 passes through the lamp box 11, in order to improve the sealing performance of the lamp box 11, the sealing sleeve 32 is arranged to block the gap between the light guide hole and the light guide ring 31, so as to improve the sealing performance of the lamp box 11, and further improve the explosion-proof performance of the lamp.

[0027] Other embodiments of the application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the application being indicated by the following claims.

[0028] It should be understood that the application is not limited to the precise construction that has been described above and illustrated in the accompanying drawings, and that various modifications and changes can be made by those skilled in the art without departing from the scope of the application. The scope of the application is limited only by the appended claims.
