Example one

Referring to fig. 1, a reflector according to the present invention is now described, which includes a mounting base 1, a first reflective component 2 and a second reflective component 3, wherein the first reflective component 2 is rotatably connected to the mounting base 1, and the second reflective component 3 is rotatably connected to the first reflective component 2; a through hole 11 for installing a lamp is formed in the mounting base 1, the lamp is installed in the through hole 11, the lamp is positioned in the middle of a cover body formed by the first reflecting component 2 and the second reflecting component 3, and light emitted by the lamp is reflected by the first reflecting component 2 and the second reflecting component 3 and then is emitted; the purpose of changing the light-emitting angle of the lamp and the brightness within the irradiation range can be achieved by adjusting the angle of the first light reflecting component 2 relative to the mounting base 1 and the angle of the second light reflecting component 3 relative to the first light reflecting component 2.

With reference to fig. 2, the first reflector assembly 2 includes a plurality of first reflectors 21 and a plurality of second reflectors 22, the plurality of first reflectors 21 and the plurality of second reflectors 22 are disposed around the through hole 11, and the lower ends of the first reflectors 21 and the lower ends of the second reflectors 22 are rotatably connected to the mounting base 1; the second reflector 22 is arranged between two adjacent first reflectors 21, and the first reflectors 21 can drive the second reflector 22 to rotate relative to the mounting base 1 when rotating relative to the mounting base 1, so that the second reflectors 22 always cover the gap between two adjacent first reflectors 21. The first reflector 21 rotates relative to the mounting base 1 to drive the second reflector 22 to rotate relative to the mounting base 1, so that the angle between the first reflector assembly 2 and the mounting base 1 is adjusted; because the second reflector 22 is arranged between the two adjacent first reflectors 21, and the first reflectors 21 can drive the second reflector 22 to rotate relative to the mounting base 1 when rotating, the second reflector 22 always covers the gap between the two adjacent first reflectors 21, and thus the light leakage problem caused by the rotation of the first reflectors 21 can be avoided.

It should be noted that the "upper end" and "lower end" referred to in the present application are a general direction, and taking the first reflector 21 as an example, the upper end of the first reflector 21 refers to an end of the first reflector 21 away from the mounting base 1, and the lower end of the first reflector 21 refers to an end of the first reflector 21 close to the mounting base 1; similarly, the upper ends and the lower ends of the second reflector 22, the third reflector 31, and the fourth reflector 32 are also the same, and detailed description thereof is omitted.

Referring to fig. 5, the second reflector assembly 3 includes a plurality of third reflectors 31 and a plurality of fourth reflectors 32, the number of the third reflectors 31 may be equal to that of the first reflectors 21, and the number of the fourth reflectors 32 may be equal to that of the second reflectors 22. The lower end of the third reflector 31 is rotatably connected to the upper end of the corresponding first reflector 21; the lower end of the fourth reflector 32 is rotatably connected to the upper end of the corresponding second reflector 22, and the fourth reflector 32 is disposed between two adjacent third reflectors 31, so that the third reflectors 31 can rotate relative to the first reflector 21 to drive the fourth reflector 32 to rotate relative to the second reflector 22, so that the fourth reflector 32 always covers the gap between two adjacent third reflectors 31. The third reflector 31 rotates relative to the first reflector 21 to drive the fourth reflector 32 to rotate relative to the second reflector 22, so that the angle between the second reflector assembly 3 and the first reflector assembly 2 is adjusted; because the fourth reflector 32 is arranged between the two adjacent third reflectors 31, and the third reflectors 31 can be driven to rotate relative to the second reflectors 22 when rotating, the fourth reflector 32 always covers the gap between the two adjacent third reflectors 31, so that the light leakage problem caused by the rotation of the third reflectors 31 can be avoided.

It should be noted that the first reflectors 21, the second reflectors 22, the third reflectors 31 and the fourth reflectors 32 surround to form a cover, one sides of the first reflectors 21, the second reflectors 22, the third reflectors 31 and the fourth reflectors 32 facing the middle of the cover are reflective surfaces, and the reflective surfaces may be flat reflective surfaces, or may also be rough surfaces such as micro-structure protrusions or recesses, or polygonal protrusions or recesses, or one or more combinations of scaly nails or orange peel lines.

In specific implementation, the plurality of first reflectors 21 may be folded in opposite directions or unfolded outward in opposite directions, when the plurality of first reflectors 21 rotate in a direction close to the through hole 11 and are folded in opposite directions to the innermost position, the side edges of two adjacent first reflectors 21 may contact each other, or there may be a certain gap, the gap is blocked by the second reflector 22, and an included angle between the outer side surface of the first reflector 21 (i.e., the surface of the first reflector 21 away from the reflective surface) and the mounting base 1 is the largest, for example, at this time, 90 ° or other angles may be provided; meanwhile, because the second reflector 22 is arranged between two adjacent first reflectors 21, and the second reflector 22 is rotatably connected with the mounting base 1, when the plurality of first reflectors 21 are oppositely gathered, the second reflectors 22 are also driven to be oppositely gathered, and the included angle between the second reflector 22 and the mounting base 1 is the largest.

When the plurality of first reflectors 21 rotate in the direction away from the through hole 11 and expand outward to the outermost position, the width of the gap between the side edges of two adjacent first reflectors 21 is the largest, at this time, the gap between two adjacent first reflectors 21 is gradually expanded from the end close to the mounting base 1 to the end away from the mounting base 1, and the angle between the outer side surface of the first reflector 21 and the mounting base 1 is the smallest, at this time, the size of the second reflector 22 in the circumferential direction is greater than or equal to the size of the gap between two adjacent first reflectors 21 in the circumferential direction, it can be understood that when the size of the second reflector 22 in the circumferential direction is equal to the size of the gap between two adjacent first reflectors 21 in the circumferential direction, the side edges of two adjacent first reflectors 21 just contact with each other, but the contact does not mean that there is no gap completely sealed between the two, but the gap between the two is as small as the acceptable degree. With the arrangement, in the process of adjusting the angle of the first reflector 21, the second reflector 22 can be ensured to completely cover the gap between two adjacent first reflectors 21 all the time. Similarly, the same is true of the second reflector 22 and the third reflector 31, which are not described in detail herein. Meanwhile, when the plurality of first reflectors 21 are unfolded outwards, the second reflectors 22 are also driven to be unfolded outwards, the second reflectors 22 are located in the gaps between two adjacent first reflectors 21, the gaps between two adjacent first reflectors 21 are completely covered, and the included angle between the second reflectors 22 and the mounting base 1 is the smallest.

Similarly, the third reflective sheets 31 can be gathered in opposite directions or expanded outward synchronously, the fourth reflective sheets 32 are driven to gather in opposite directions or expand outward synchronously, and the third reflective sheets 31 cannot transmit light all the time. For the specific process, reference is made to the above description, and details are not repeated herein.

Compared with the prior art, the reflector provided by the application has the advantages that the first reflector 21 and the second reflector 22 can rotate relative to the mounting base 1 to adjust the light emitting angle of the lamp, the second reflector 22 is arranged between every two adjacent first reflectors 21, so that the second reflectors 22 can always cover the gap between every two adjacent first reflectors 21 in the adjusting process, light is prevented from being emitted from the gap between every two adjacent first reflectors 21, and the light emitting efficiency is improved; meanwhile, the fourth reflector 32 is arranged between the two adjacent third reflectors 31, the third reflectors 31 can rotate relative to the first reflector 21, and the fourth reflector 32 can rotate relative to the second reflector 22, so that the fourth reflector 32 can always cover the gap between the two adjacent third reflectors 31 in the adjusting process, light can be prevented from being emitted from the gap between the two adjacent third reflectors 31, and the light emitting efficiency can be improved; in addition, the first light reflecting component 2 and the second light reflecting component 3 are arranged to be capable of independently rotating and adjusting, so that the angle adjustment of the light emitting angle on different areas in the circumferential direction inside the light reflecting surface can be realized, the adjustment precision of the light emitting angle is improved, and more angle adjustment requirements are met.

It should be further noted that, in this embodiment, the shapes of the reflective surface of the first reflective sheet 21, the reflective surface of the second reflective sheet 22, the reflective surface of the third reflective sheet 31, and the reflective surface of the fourth reflective sheet 32 may be set as planes, at this time, an included angle is formed between the extending direction of the first reflective sheet 21, the extending direction of the second reflective sheet 22, the extending direction of the third reflective sheet 31, and the extending direction of the fourth reflective sheet 32 and the axis of the through hole 11, and the included angle ranges from 0 ° to 90 °; in other embodiments, the shapes of the reflective surface of the first reflector 21, the reflective surface of the second reflector 22, the reflective surface of the third reflector 31, and the reflective surface of the fourth reflector 32 may also be other shapes such as a curved surface or a folded surface, which is not limited herein.

Specifically, the first reflector 21 and the third reflector 31 may be connected by a rotating shaft, a groove may be formed in the first reflector 21, and the rotating shaft is located in the groove, so that a gap between the upper end of the first reflector 21 and the lower end of the third reflector 31 is reduced or no gap is formed, and light leakage caused by the gap between the first reflector 21 and the third reflector 31 is reduced. It will be appreciated, of course, that the connection between the second retroreflective sheeting 22 and the fourth retroreflective sheeting 32 is similar and will not be described in detail herein.

In an embodiment, the reflector can also include the piece that blocks light, the one end circumference of piece that blocks light surrounds in the outside of first reflection of light subassembly 2, the other end circumference of piece that blocks light surrounds in the outside of second reflection of light subassembly 3, in order to cover the clearance between first reflection of light subassembly 2 and the second reflection of light subassembly 3, concretely, can set up adhesive part (for example, magic subsides, sticky etc.) on the outside surface of first reflection of light subassembly 2 and the outside surface of second reflection of light subassembly 3, then cover the piece that blocks light in the clearance between first reflection of light subassembly 2 and the second reflection of light subassembly 3 again, avoid taking place the light leak because of the clearance between first reflection of light piece 21 and the third reflection of light piece 31, can specifically select the setting according to actual need.

In practical applications, the rotation of the first reflector 21 relative to the mounting base 1 may be driven in various manners, for example, the first reflector 21 may be driven to rotate in a manual manner, or the first reflector 21 may be driven to rotate in a manner of an electric push rod or a hydraulic push rod, which is not limited to this, as long as the rotation of the first reflector 21 relative to the mounting base 1 can be realized, and a person skilled in the art may select the setting according to actual needs. Similarly, the third reflector 31 rotates relative to the first reflector 21.

In the present embodiment, as shown in fig. 1 and fig. 7, the reflector further includes a first driving ring 4 and a first connecting member 5, the first driving ring 4 is sleeved outside the mounting seat 1, and the first driving ring 4 can move along the axial direction of the through hole 11 relative to the mounting seat 1; one end of the first connecting piece 5 is rotationally connected to the first driving ring 4, and the other end of the first connecting piece 5 is rotationally connected to the first reflector 21; the first driving ring 4 moves axially relative to the mounting base 1 along the through hole 11 to drive the first connecting member 5 to rotate relative to the mounting base 1, and then drives the first reflector 21 and the second reflector 22 to rotate relative to the mounting base 1, so that the first reflector 21 and the second reflector 22 are synchronously gathered together or synchronously expanded outwards in opposite directions, and the light emitting angle of the first reflector assembly 2 is adjusted. When the light emitting angle needs to be adjusted, a user can manually push the first driving ring 4 to move towards the direction close to the first reflector 21, the first connecting piece 5 is extruded to start to rotate relative to the first driving ring 4 and the first reflector 21, and meanwhile, the first connecting piece 5 starts to apply pressure to the first reflector 21, so that the first reflector 21 gathers towards the middle of the first reflector assembly 2, meanwhile, the second reflector 22 gathers towards the middle of the first reflector assembly 2 under the action of the first reflector 21, the light emitting angle of the first reflector assembly 2 is reduced, and the brightness in the irradiation range is increased; the first driving ring 4 moves towards the direction far away from the first light reflecting piece 21, the first connecting piece 5 starts to rotate reversely under the action of pulling force, meanwhile, the first connecting piece 5 starts to pull the first light reflecting piece 21, so that the first light reflecting piece 21 is unfolded back to the middle part of the first light reflecting component 2, meanwhile, the second light reflecting piece 22 is also unfolded back to the middle part of the first light reflecting component 2 under the action of the first light reflecting piece 21, the light emitting angle of the first light reflecting component 2 is increased, and the brightness in the irradiation range is reduced.

In the embodiment, the reflector further comprises a second driving ring 6 and a second connecting piece 7, the second driving ring 6 is sleeved outside the first driving ring 4, and the second driving ring 6 can move relative to the first driving ring 4 along the axial direction of the through hole 11; one end of the second link 7 is rotatably connected to the second drive ring 6, and the other end of the second link 7 is rotatably connected to the third reflector 31. For specific working principles and processes, reference may be made to the above description, which is not repeated herein.

In one embodiment, one side of the second driving ring 6 facing the first driving ring 4 is provided with an axially extending strip-shaped groove (not shown), and one side of the first driving ring 4 facing the second driving ring 6 is provided with a mounting hole (not shown); the reflector further comprises an operating member (not shown), one end of the operating member can extend into the strip-shaped groove and be detachably mounted in the mounting hole, and the other end of the operating member extends out of the end face, away from the first reflective component 2, of the first driving ring 4 for operation by a user. Specifically, when the angle of the first reflective component 2 needs to be adjusted, one end of the operating element extends into the strip-shaped groove and is fixed in the mounting hole, and the angle of the first reflective component 2 can be adjusted by pulling the other end of the operating element by a user, so that the problem that the user cannot contact with the first driving ring 4 and push the first driving ring 4 to axially move relative to the mounting seat 1 because the first driving ring 4 is blocked by the lamp after the lamp is mounted in the through hole 11 can be avoided; after finishing the angle adjustment of the first reflecting component 2, the operating part is detached from the mounting hole, so that the operating part can be prevented from influencing the angle adjustment of the second reflecting component 3.

Specifically, the first connecting element 5 may be a connecting rod, or may be in other forms, as long as both ends of the first connecting element 5 can be respectively and rotatably connected to the first driving ring 4 and the first reflector 21, and similarly, the second connecting element 7 is also the same, and details thereof are not repeated herein. The first connecting piece 5 and the first driving ring 4 can be connected in a rotating manner in various ways, for example, one end of the first connecting piece 5 close to the first driving ring 4 is provided with two first shaft sleeves which are arranged oppositely, the first driving ring 4 is provided with a second shaft sleeve, the second shaft sleeve is positioned between the two first shaft sleeves, and the second shaft sleeve and the two first shaft sleeves are connected through a first hinge shaft; it is of course understood that the way of rotationally connecting the first connecting member 5 to the first drive ring 4 may also be other forms including, but not limited to, an articulated form, and those skilled in the art can select the arrangement according to actual needs. Similarly, the connection between the first connecting element 5 and the first reflector 21, the connection between the second connecting element 7 and the second driving ring 6, the connection between the second connecting element 7 and the third reflector 31, the connection between the first reflector 21 and the mounting base 1, the connection between the second reflector 22 and the mounting base 1, and the rotational connection between the first reflector 21 and the third reflector 31 are also the same, and detailed description is omitted.

When only the angle of the second reflecting component 3 needs to be adjusted, the first reflecting component 2 can be kept still, and only the angle of the second reflecting component 3 needs to be adjusted by rotating the third reflecting piece 31. When the first reflecting component 2 needs to be gathered, the angles of the first reflecting component 2 and the second reflecting component 3 can be adjusted simultaneously. To illustrate the adjustment that the light-emitting angle needs to be reduced, the first reflector 21 rotates relative to the mounting base 1 in the direction close to the through hole 11, and drives the second reflector 22 to rotate relative to the mounting base 1 in the direction close to the through hole 11, so as to gather the first reflector assembly 2; when the angles of the first light reflecting component 2 and the second light reflecting component 3 need to be kept consistent, when the first light reflecting component 2 gathers together, because the third light reflecting piece 31 is rotationally connected with the first light reflecting piece 21, when the first light reflecting piece 21 rotates towards the direction close to the through hole 11 relative to the mounting base 1, the third light reflecting piece 31 rotates towards the direction far away from the through hole 11 relative to the first light reflecting piece 21, at the moment, the third light reflecting piece 31 needs to rotate towards the direction close to the through hole 11 simultaneously, the fourth light reflecting piece 32 is driven to rotate relative to the second light reflecting piece 22, and the second light reflecting component 3 gathers together along with the first light reflecting component 2. Similarly, the deployment principle of the first reflective component 2 and the deployment principle of the second reflective component 3 are similar, and the detailed description thereof is omitted.

In an embodiment, as shown in fig. 2, two first receiving grooves 211 are disposed on the first light-reflecting sheet 21, the second light-reflecting sheets 22 adjacent to both sides of the first light-reflecting sheet 21 are movably received in the two first receiving grooves 211 respectively, and are limited in the first receiving grooves 211 along the thickness direction of the first receiving grooves 211, when the first light-reflecting sheet 21 rotates relative to the mounting base 1, the second light-reflecting sheet 22 is driven to rotate relative to the mounting base 1 through the limitation of the first receiving grooves 211 on the second light-reflecting sheets 22. Here, the thickness direction of the first receiving groove 211 refers to: in the same direction as the thickness direction between the opposite side surfaces (light-reflecting surface and outer surface) of the first retroreflective sheet 21. Similarly, the third reflective sheet 31 is provided with two second receiving grooves 311, and the adjacent fourth reflective sheets 32 on two sides of the third reflective sheet 31 are movably received in the two second receiving grooves 311 respectively, and are limited in the second receiving grooves 311 along the thickness direction of the second receiving grooves 311.

In an embodiment, with reference to fig. 2, the first reflector 21 includes a first blade 212 and two first interlayer members 213, a lower end of the first blade 212 is rotatably connected to the mounting base 1, the two first interlayer members 213 are respectively disposed on two sides of a surface of the first blade 212 facing away from the light-reflecting surface, and the two first interlayer members 213 respectively form corresponding first receiving grooves 211 with the first blade 212. Two first accommodating grooves 211 are respectively used for accommodating two adjacent second reflectors 22, that is, two adjacent first reflectors 21 are accommodated and limited by two first accommodating grooves 211, and when the first reflectors 21 rotate, the two adjacent first reflectors 21 drive the second reflectors 22 to rotate through the two first accommodating grooves 211, so that the rotation of the second reflectors 22 is more stable. Preferably, a side of the first blade 212 facing the through hole 11 is a light reflecting surface, and the first interlayer member 213 is disposed at a side opposite to the light reflecting surface. In this way, the first interlayer member 213 may prevent the light reflecting surface of the first blade 212 from being blocked, thereby ensuring the light reflecting efficiency of the light reflecting surface of the first blade 212. It is understood that, the first receiving groove 211 may be directly formed on the end surface of the first reflective sheet 21 near the end of the second reflective sheet 22, which requires the first reflective sheet 21 to have a certain thickness, so as to conveniently form the first receiving groove 211; in other embodiments, the first receiving groove 211 may be formed in other manners, and those skilled in the art can select the first receiving groove according to actual needs.

Similarly, as shown in fig. 5, the third reflective sheet 31 includes a second blade 312 and two second interlayer members 313, the lower end of the second blade 312 is rotatably connected to the first reflective sheet 21, the two second interlayer members 313 are respectively disposed on two sides of one surface of the second blade 312 departing from the reflective surface, and the two second interlayer members 313 respectively form corresponding second receiving grooves 311 with the second blade 312. The specific structure and process can refer to the above description, and are not repeated herein.

In an embodiment, an included angle between the surface of the first interlayer 213 opposite to the first blade 212 and the second reflector 22 is an acute angle, that is, the surface of the first interlayer 213 opposite to the first blade 212 is not parallel to the second reflector 22, so that the second reflector 22 is prevented from being locked and unable to rotate when the first reflector 21 drives the second reflector 22 to rotate. The surface of the first interlayer member 213 opposite to the first blade 212, that is, the groove wall where the first receiving groove 211 and the second reflector 22 abut against each other, may be a plane having an included angle with the second reflector 22, or an arc, and is not limited thereto, and those skilled in the art can select the arrangement according to actual needs.

Similarly, the surface of the second cladding 313 opposite the second blade 312 forms an acute angle with the second reflector 22. Reference is made to the above description for specific principles and processes, which are not repeated herein.

The invention further provides a lighting device which comprises a lamp and the reflector, wherein the lamp is arranged in the through hole 11, the lamp is detachably connected with the reflector, specifically, as shown in fig. 8, a bayonet ring 12 is arranged on the hole wall of the through hole 11, a clamping part 121 is arranged on the bayonet ring 12, and the lamp can be detachably mounted on the reflector through the connection of the clamping part 121 and a matching clamping part (not shown) on the lamp. The lighting device provided by the embodiment of the invention has the reflector in any one of the embodiments, so that all the beneficial effects of the reflector are achieved, and the description is omitted.

Example two

This embodiment is substantially the same as the first embodiment, and the differences are only that: as shown in fig. 3 and 4, the first light-reflecting sheet 21 includes a third blade 216 and a fourth blade 217, the third blade 216 is located on one side of the fourth blade 217 away from the light-reflecting surface, the middle position of the third blade 216 is connected to the middle position of the fourth blade 217, a gap between the fourth blade 217 and the third blade 216 is separated to form two first receiving grooves 211, the two first receiving grooves 211 are respectively used for receiving two adjacent second light-reflecting sheets 22, that is, two adjacent first light-reflecting sheets 21 receive one second light-reflecting sheet 22 through the two first receiving grooves 211, and when the first light-reflecting sheet 21 rotates, two adjacent second light-reflecting sheets 22 rotate relative to the mounting base 1 by being driven by the two first receiving grooves 211.

Further, the gap between the fourth blade 217 and the third blade 216 gradually increases from the middle position toward the two ends far away from the middle position, so as to set up, the groove wall of the first accommodating groove 211 and the second reflective sheet 22, which are mutually abutted, cannot be parallel to the second reflective sheet 22, and in the process that the first reflective sheet 21 drives the second reflective sheet 22 to rotate, the situation that the second reflective sheet 22 is jammed and cannot rotate can be avoided. Similarly, the groove walls of the first receiving groove 211 and the second reflective sheet 22, which are abutted against each other, may be arc-shaped, or may be a plane having an included angle with the second reflective sheet 22, which is not limited to this, and those skilled in the art can select the setting according to actual needs.

Further, the gap between the sixth blade 317 and the fifth blade 316 gradually increases from the center position toward both ends away from the center position. For the specific structure and process, reference may be made to embodiment two, which is not described herein again.

It should be noted that all the rotation connection manners referred to in the present application include, but are not limited to, hinging, as long as the rotation connection can be realized, and the arrangement can be selected by those skilled in the art according to actual needs.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
