Description

Technical Field

[0001] This application relates to the field of lighting equipment technology, and in particular to a floodlight that can be used with streetlights. Background Technology

[0002] Streetlights typically have very fixed installation methods, and because the location of the streetlight poles is relatively fixed, the installation points of streetlights are also relatively fixed. Moreover, once a streetlight is installed on a streetlight pole, its illumination angle is not easily changed. In terms of usage flexibility, it is not as good as floodlights. However, although floodlights are more flexible in use, their installation stability and angular stability do not meet the requirements of streetlights. Utility Model Content

[0003] The purpose of this application is to provide a floodlight that balances stability and flexibility.

[0004] To achieve the above objectives, this application provides a floodlight that can be used with streetlights: it includes a lamp body, the lamp body is provided with an LED light-emitting panel protected by a transparent cover, the lamp body is provided with a plug-in sleeve on the outside, which is suitable for fixed connection with the extension end of the streetlight pole, and both sides of the lamp body are provided with mating shafts, which are suitable for movably connecting a projection frame through positioning parts and bolts, so as to ensure the flexibility of angle adjustment of the lamp body in the floodlight installation mode.

[0005] As a preferred embodiment, the end of the mating shaft is provided with a coaxial fitting groove, the inner wall of the fitting groove is provided with a keyway, the positioning member includes an inner ring, the outer surface of the inner ring has a key plate, adapted to mate with the keyway; both ends of the projection frame have coaxial constraint rings, which respectively mate with the two mating shafts to form a rotating pair, the mating shaft is provided with a coaxial internal thread hole in the fitting groove, the end face of the inner ring is provided with a coaxial limiting ring, adapted to be in close contact with the constraint ring; the end face of the inner ring is provided with a light hole communicating with the end face of the limiting ring, the bolt is adapted to pass through the light hole and screw into the internal thread hole, and the contact friction force can suppress the rotation of the lamp body relative to the projection frame to a certain extent.

[0006] As a preferred embodiment, both constraint rings have several anti-rotation slots on their opposite end faces, and the limiting ring has anti-rotation teeth on its end face facing the constraint ring, which are suitable for engaging with the anti-rotation slots to further enhance the angular stability of the lamp body relative to the projection frame.

[0007] As a preferred embodiment, the anti-rotation slots on each of the constraint rings are arranged equidistantly around the axis of the constraint ring, forming multiple equidistant angular differences.

[0008] As a preferred embodiment, the number of anti-rotation teeth on the limiting ring corresponds to the number of anti-rotation slots on the constraint ring. The anti-rotation teeth on each limiting ring are equidistantly arranged around the axis of the limiting ring, which can disperse the shear stress generated by the rotation tendency of the lamp body relative to the projection frame, and further improve the lamp body's ability to maintain the angle relative to the projection frame.

[0009] As a preferred embodiment, the mating shaft is fixedly connected to the lamp body via a coaxial wear-resistant seat, the diameter of which is larger than that of the mating shaft, and the constraint ring is located between the wear-resistant seat and the limiting ring; the end of the limiting ring facing away from the inner ring also has a coaxial protective ring, and the larger end of the bolt is suitable to be recessed into the protective ring to reduce the risk of the bolt loosening due to impact.

[0010] As a preferred embodiment, the projection frame includes a fixed plate with several through slots, and cantilever arms on both sides of the fixed plate. Two constraint rings are located at the ends of the two cantilever arms, and the lamp body is located between the two cantilever arms.

[0011] As a preferred embodiment, the inner wall of the plug sleeve has an anti-rotation strip, and the lower side wall of the plug sleeve also has a through hole that passes through the inner and outer walls, for bolts and other connecting parts to pass through and fix the projection frame to the attachment surface.

[0012] Compared with the prior art, the beneficial effects of this application are as follows: (1) By designing a plug-in sleeve and a mating shaft structure that can be used with the projection frame on the lamp body, the lamp body can be installed in two ways: street lamp and floodlight. It can have the installation stability of street lamp and the adjustment flexibility of floodlight illumination angle. (2) By designing a positioning component structure that cannot rotate relative to the mating shaft, using bolts for constraint, and designing a locking structure on the opposite face of the constraint ring and the limit ring, the projection angle can be adjusted according to actual needs in the floodlight mode, and the projection angle can be kept stable when no adjustment is needed.

[0021] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0024] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0025] like Figure 1-7 The floodlight shown can be used with streetlights. It includes a lamp body 1 as the main body. The lamp body 1 is equipped with an LED light-emitting panel 110 protected by a transparent cover, which is the light source of the entire lamp body 1. The lamp body 1 is provided with a plug-in sleeve 130 for fixed connection with the extension end of the streetlight pole. The inner wall of the plug-in sleeve 130 has an anti-rotation strip 131, which can be inserted into the anti-rotation groove on the outer side of the extension end of the streetlight pole, thereby effectively preventing the plug-in sleeve 130 from rotating relative to the extension end of the streetlight pole. The lower side wall of the plug-in sleeve 130 is also provided with a through hole 132 that penetrates the inner and outer walls. In this way, rainwater is not easy to enter the plug-in sleeve 130 through the through hole 132. The through hole 132 is used for bolts 4 and other connecting parts to pass through and fix the plug-in sleeve 130 to the extension end of the streetlight pole. The anti-rotation strip 131 can effectively share the shear stress on the bolts 4. This is the streetlight installation mode.

[0026] Both sides of the lamp body 1 are provided with mating shafts 120. The mating shafts 120 are adapted to be movably connected to the projection frame 2 via positioning parts 3 and bolts 4. Each mating shaft 120 is fixedly connected to the lamp body 1 via a coaxial wear-resistant seat 121. The diameter of the wear-resistant seat 121 is larger than the diameter of the mating shaft 120. The wear-resistant seat 121 can directly contact the projection frame 2 to provide rotational friction resistance.

[0027] The end of the mating shaft 120 is provided with a coaxial fitting groove 122. The inner wall of the fitting groove 122 is provided with a keyway 124. There are several keyways 124, which are evenly arranged along the inner wall of the fitting groove 122. Each keyway 124 extends to the end of the mating shaft 120. The positioning member 3 includes an inner ring 301, which is suitable for being fitted into the fitting groove 122. The outer side of the inner ring 301 has a key plate 302. The key plate 302 and the inner ring 301 form a spline structure. The number and position of the key plates 302 correspond to the keyways 124, and they fit one-to-one with the keyways 124, which can effectively prevent the positioning member 3 from rotating relative to the mating shaft 120.

[0028] The projection frame 2 has coaxial constraint rings 204 at both ends. The specific structure of the projection frame 2 includes a fixing plate 201. The fixing plate 201 has several through slots 202, which are both horizontal and vertical. Each through slot 202 is elongated and its width is slightly larger than the diameter of the bolt 4's screw part, which facilitates the bolt 4 to pass through and make flexible position adjustments. The bolt 4 can well constrain the fixing plate 201 to different attachment surfaces. The fixing plate 201 has cantilever arms 203 on both sides. The two cantilever arms 203 are located on the same side of the fixing plate 201 and are usually arranged symmetrically. The two constraint rings 204 are located at the ends of the two cantilever arms 203, and can be used with the two mating shafts 120 to form a rotating pair. At this time, the plug sleeve 130 does not need to participate in the installation. The lamp body 1 is the floodlight installation mode.

[0029] The mating shaft 120 has a coaxial internal threaded hole 123 in the fitting groove 122. The end face of the inner ring 301 has a coaxial limiting ring 303 for close contact with the constraint ring 204. The constraint ring 204 is located between the wear-resistant seat 121 and the limiting ring 303. The contact friction force can suppress the rotation of the lamp body 1 relative to the projection frame 2, thereby maintaining the angle of the light projected by the lamp body 1 to a certain extent.

[0030] To improve the stability of the positioning element 3 in restricting the constraint ring 204, the end face of the inner ring 301 is provided with a light hole 306 that connects to the end face of the limiting ring 303. The bolt 4 can pass through the light hole 306 and screw into the inner threaded hole 123. In this way, even if the positioning element 3 is subjected to the rotational friction of the constraint ring 204, the tightness of the bolt 4 will not be affected. Thus, the positioning element 3 and the bolt 4 mating with it can remain stable. The end of the limiting ring 303 facing away from the inner ring 301 also has a coaxial protective ring 304. The larger end of the bolt 4 is precisely recessed into the protective ring 304. In this way, the bolt 4 in the positioning element 3 is not easily loosened by impact. The bolt 4 is usually a type that can be used with a hex wrench. In this way, the outer side of the larger end of the bolt 4 can be very close to the inner wall of the protective ring 304, with a higher degree of fit and a lower probability of the larger end of the bolt 4 being impacted.

[0031] To ensure the stability of the lamp body 1 after angle adjustment in floodlight mode, several anti-rotation slots 205 are provided on the opposite end faces of the two constraint rings 204. The anti-rotation slots 205 on each constraint ring 204 are equidistantly arranged around the axis of the constraint ring 204. The end face of the limiting ring 303 facing the constraint ring 204 has anti-rotation teeth 305, which can engage with the anti-rotation slots 205. The number of anti-rotation teeth 305 on the limiting ring 303 corresponds to the number of anti-rotation slots 205 on the constraint ring 204. The anti-rotation teeth 305 on each limiting ring 303 are equidistantly arranged around the axis of the limiting ring 303. In this way, all the anti-rotation teeth 305 can engage with all the anti-rotation slots 205, thereby dispersing the shear stress.

[0032] Working principle: The lamp body 1 has two installation modes. The first is a more flexible floodlight mode, where the installation position is not limited, but the projection frame 2 needs to be installed through the positioning part 3 and bolts 4. The angle of the light projected by the lamp body 1 can be adjusted according to actual needs. The positioning part 3 is made of one piece of plastic. During the adjustment process, a rotational force is applied to the lamp body 1, and the anti-rotation tooth 305 on the end face of the limiting ring 303 will be slightly squeezed and deformed. It first disengages from the original anti-rotation groove 205, and then slides into the new anti-rotation groove 205 in the direction of rotation, and regains stability. After the anti-rotation tooth 305 disengages and overlaps with the anti-rotation groove 205 multiple times, a large range of angle adjustment can be completed and stability can be maintained. The second is a more fixed street light mode. In this mode, the projection frame 2 usually needs to be removed to reduce the load on the lamp body 1. That is, only the lamp body 1 is retained and connected to the extension end of the street light pole through the plug sleeve 130 at the tail, and fixed with bolts 4 to complete the installation.
