[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0021] The lamp disclosed in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0022] like Figures 1 to 4 As shown, the present application discloses a lamp, which includes a first reflector 100 , a second reflector 200 , a housing 300 , a light source 400 and a circuit board 500 .

[0023] The first reflector 100 and the second reflector 200 are light distribution devices in the lamp, which can reflect light. The shell 300 is the basic component of the lamp, which can install other components in the lamp and play a protective role. The light source 400 is electrically connected to the circuit board 500, so that the circuit board 500 can power the light source 400, so that the light source 400 emits light to realize the lighting function of the lamp.

[0024] In the present application, the first reflector 100, the second reflector 200, the light source 400 and the circuit board 500 are all arranged in the housing 300, so that the housing 300 can install and protect the first reflector 100, the second reflector 200, the light source 400 and the circuit board 500. The light source 400 is electrically connected to the circuit board 500, the first reflector 100 is opposite to the light source 400, and the first reflector 100 is opposite to the second reflector 200, so that part of the light emitted by the light source 400 can be injected into the first reflector 100, and the light injected into the first reflector 100 can be collimated and injected into the second reflector 200 after being reflected by the first reflector 100, and the second reflector 200 is used to reflect the light emitted from the first reflector 100, and the second reflector 200 collimates the light and emits it from the light exit hole 341 of the housing 300.

[0025] That is to say, in the present application, the light emitted from the light source 400 can pass through the collimated reflection twice by the first reflector 100 and the second reflector 200, so that the light that does not meet the collimated reflection angle can be filtered. Compared with the reflection of the reflector once, the two collimated reflections can filter out more stray light, that is, more stray light is retained in the housing 100, so that the angle of the light emitted from the light outlet hole 341 is more consistent with the expected angle, thereby reducing the glare problem of the lamp. In addition, when the lighting effect of the lamp meets the basic conditions, those skilled in the art can appropriately reduce the aperture size of the light outlet hole 341, so as to reduce the angle of the light emitted from the light outlet hole 341, so as to reduce the glare of the lamp. Specifically, the aperture size of the light outlet hole 341 can be designed according to actual conditions, and the present application does not impose specific restrictions on the aperture size of the light outlet hole 341.

[0026] The lamp disclosed in the embodiment of the present application improves the structure of the lamp in the related art, that is, in the present application, the first reflector 100 and the second reflector 200 are provided to collimate and reflect the light emitted from the light source 400 twice, that is, the stray light in the light source 400 is filtered for multiple times in succession, so that a large part of the stray light propagating along a larger deflection angle in the light is filtered, so that the angle of the light emitted from the light exit hole 341 meets the expected exit angle, so that the light emitted from the light exit hole 341 at various angles can be avoided, and the problem of large glare generated by the light emitted from the light exit hole 341 can be reduced. The present application can solve the problem of large glare generated by the lamp in the background art.

[0027] In the present application, the inner side wall of the housing 300 can enclose a first positioning space 310, and the circuit board 500 is positioned in the first positioning space 310. In this case, the circuit board 500 is installed in the first positioning space 310, so that the circuit board 500 can be relatively stably installed in the housing 300. At the same time, the inner side wall of the housing 300 is used to enclose the first positioning space 310, that is, the circuit board 500 is stably installed by using the structure of the housing 300 itself, thereby avoiding the need for additional positioning components to position and install the circuit board 500.

[0028] In the lamp disclosed in the embodiment of the present application, the first reflector 100 may have a first reflective surface 110. The light emitted by the light source 400 is collimated and incident into the second reflector 200 after being reflected by the first reflective surface 110. The first reflective surface 110 may include a plurality of mutually connected protrusions. In this case, the plurality of mutually connected protrusions form a phosphorus armor design for the first reflective surface 110, so that the first reflective surface 110 can mix the light reflected on the first reflector 100, which is conducive to eliminating yellow spots in the light, and further conducive to improving the quality of the light. In another optional technical solution, the first reflective surface 110 may include a plurality of mutually connected recessed portions. The plurality of mutually connected recessed portions can also form a phosphorus armor design for the first reflective surface 110, which can also achieve light mixing, which is conducive to eliminating yellow spots in the light and can improve the quality of the light.

[0029] In the lamp disclosed in the embodiment of the present application, the second reflector 200 may have a second reflective surface 210, and the second reflective surface 210 is used to reflect the light emitted from the first reflector 100, and the second reflective surface 210 is a vacuum-plated reflective surface. In this case, the vacuum-plated reflective surface can improve the reflection efficiency of the second reflective surface 210, thereby facilitating the improvement of the reflection efficiency of the light in the lamp.

[0030] In an optional technical solution, the shell 300 may include a shell body 320, an end cap 330 and an aperture 340. The shell body 320 and the aperture 340 may be surrounded by a cylindrical member. The number of the end caps 330 may be two, so that the two end caps 330 may be respectively arranged at the two ends of the cylindrical member, so that the end caps 330 and the aperture 340 are connected to the shell body 320 to form a closed inner cavity 350. The first reflector 100, the second reflector 200, the light source 400 and the circuit board 500 may be arranged in the inner cavity 350, and a plurality of light exit holes 341 are provided on the aperture 340. In this case, the inner cavity 350 is a closed space, which is conducive to better protection of the first reflector 100, the second reflector 200, the light source 400 and the circuit board 500. At the same time, the closed inner cavity 350 is conducive to preventing debris from entering the interior of the lamp and adversely affecting the lighting effect of the lamp.

[0031] In a further technical solution, the surface of the aperture 340 facing the inner cavity 350 can be the light incident surface 342, and the surface of the aperture 340 facing away from the inner cavity 350 can be the light emitting surface 343. The light emitting hole 341 passes through the light incident surface 342 and the light emitting surface 343. The opening of the light emitting hole 341 located on the light incident surface 342 has a first diameter, and the opening of the light emitting hole 341 located on the light emitting surface 343 has a second diameter. The first diameter is smaller than the second diameter. The side wall of the light emitting hole 341 is conical, and the axis of the cone is perpendicular to the plane where the light incident surface 342 is located. In this case, the aperture of the light exit hole 341 located on the light exit surface 343 is larger than the aperture of the light exit hole 341 located on the light incident surface 342, that is, the light exit hole 341 is guided at an oblique angle on the light exit surface 343, so that the light entering the light exit hole 341 will not interfere with the hole wall of the light exit hole 341 located on the light exit surface 343, causing reflection and generating glare, which is beneficial to further reduce the glare of the lamp.

[0032] In an optional technical solution, the shell body 320 may include a first side wall 321 and a second side wall 322 that are adjacent and connected. One of the inner surfaces of the first side wall 321 and the second side wall 322 may be provided with a first positioning recess 3211, and the other may be provided with a first positioning protrusion 3221. One end of the second reflector 200 may have a second positioning recess 230, and the other end of the second reflector 200 may have a second positioning protrusion 220. The first positioning recess 3211 is positioned and matched with the second positioning protrusion 220, and the first positioning protrusion 3221 is positioned and matched with the second positioning recess 230. In this case, the second reflector 200 and the shell body 320 can both be positioned and installed with each other through their own structures, and the first side wall 321, the second side wall 322 and the second reflector 200 can achieve a stable triangular support installation structure after achieving positioning and matching, which is conducive to improving the stability of the second reflector 200 installed on the shell body 320.

[0033] In the lamp, the emission direction of the light is inclined relative to the light emitting surface 343 of the lamp, which can realize the polarization setting of the light in the lamp. Those skilled in the art know that polarization is conducive to controlling the intensity and direction of the light, thereby achieving a better lighting effect. By using polarization technology, the glare caused by reflection and refraction can be reduced to improve visual comfort. In the lamp disclosed in the embodiment of the present application, the shell body 320 can also include a third side wall 323, the third side wall 323 is connected to the second side wall 322, the first side wall 321 is opposite to the third side wall 323, the inner surface of the first side wall 321 and the inner surface of the third side wall 323 can be provided with a first mounting groove 324, and both ends of the aperture 340 can be set in different first mounting grooves 324, and are inclined relative to the first side wall 321 and the third side wall 323. In this case, the two ends of the diaphragm 340 can be installed in the first installation grooves 324 at different heights to achieve an inclined installation of the diaphragm 340 relative to the first side wall 321 and the third side wall 323, thereby achieving the polarization setting of the light. The above method is relatively simple and easy to implement.

[0034] At the same time, considering that the optical path of the light in the lamp will affect the volume of the lamp and the size of the glare generated by the lamp, in the present application, a plurality of first mounting grooves 324 may be provided on the inner surface of the first side wall 321, and a plurality of first mounting grooves 324 may be provided on the inner surface of the third side wall 323, and the number of the first mounting grooves 324 on the first side wall 321 is equal to the number of the first mounting grooves 324 on the third side wall 323, and the positions correspond one to one, so that the aperture 340 can be installed in two first mounting grooves 324 at different heights, so that the optical path of the light reflected from the second reflector 200 to the aperture 340 can be adjusted. In an optional technical solution, the aperture 340 can be installed in a first mounting groove 324 with a higher height, so that the light reflected from the second reflector 200 to the aperture 340 has a larger optical path, which is conducive to the aperture 340 filtering more light with a larger deflection angle, and can avoid the lamp from generating a larger glare.

[0035] It should be noted that, when the volume of the lamp is determined, the first installation slot 324 can be set as far away from the second reflector 200 as possible, that is, the aperture 340 can have a higher installation height relative to the second reflector 200, which is conducive to reducing the glare generated by the lamp. In the design process of the lamp, if the glare effect generated by the installation height of the aperture 340 relative to the second reflector 200 cannot be determined, a plurality of first installation slots 324 with different installation heights can be opened in the shell body 320, and the size of the glare generated by the lamp can be detected by installing the aperture 340 in the first installation slots 324 with different heights. The specific installation height of the aperture 340 can be determined on the basis that the size of the glare generated by the lamp meets the design requirements, thereby determining the specific size of the lamp. In other words, the installation height of the aperture 340 is related to the filtering effect of the aperture 340 on light and the size of the volume of the lamp. The technician can select the position height of the first installation slot 324 that takes into account the glare size and the volume of the lamp by installing the aperture 340 in the first installation slots 324 with different heights.

[0036] To achieve installation of the lamp, in the lamp disclosed in the embodiment of the present application, a second installation groove 325 may be provided on the outer surface of the first side wall 321 and the outer surface of the third side wall 323. In this case, the provision of the second installation groove 325 facilitates the cooperation between the lamp and the mounting bracket to achieve installation of the lamp.

[0037] In the lamp disclosed in the embodiment of the present application, the lamp may further include a fastener, a mounting hole 331 may be provided on the end cap 330, the inner surface of the first side wall 321 and the inner surface of the third side wall 323 may include a mounting protrusion 3231 facing the inner cavity 350, and the fastener passes through the mounting hole 331 and is threadedly connected with the mounting protrusion 3231. In this case, a threaded hole may be provided on the mounting protrusion 3231, so that the fastener can pass through the mounting hole 331 and achieve threaded matching with the threaded hole on the mounting protrusion 3231, thereby achieving a fixed connection between the end cap 330 and the shell body 320. At the same time, the mounting protrusion 3231 only needs to be provided with threaded holes at both ends of the shell body 320 to achieve connection, so that the setting of the mounting protrusion 3231 can also be equivalent to the reinforcing rib on the shell body 320, which is conducive to improving the structural strength of the shell body 320.

[0038] It should be noted that, in this article, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0039] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
