Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to fig. 1, 2 and 4, an embodiment of the present invention provides a reflector, which includes two reflectors 1 assembled into a bowl, a fixed ring 2 fixed in position and provided for installing a lamp bead 7, a driving ring 3 disposed above the fixed ring 2 and capable of moving up and down, and two sets of link assemblies 4 disposed between the fixed ring 2 and the driving ring 3. Each link assembly 4 has a movable end 42 driven by the driving ring 3 to move between the fixed ring 2 and the driving ring 3, the two movable ends 42 are located at opposite sides of the fixed ring 2, the two reflectors 1 are respectively connected to the two movable ends 42, and the fixed ring 2 is located in a reflective region enclosed by the two reflectors 1. Among the prior art, in the use of ceiling lamp down lamp, in order to reach shot-light effect and reflection of light illuminating effect, need adopt the lamps and lanterns of two kinds of different specifications usually, not only can influence the unity of headspace like this but also can influence whole aesthetic measure, and two sets of equipment arrangements can obviously increase a lot of investment cost in addition. In addition, some proposals exist in the prior art for adjusting the expansion angle of the reflector to change the incident direction of the light, the most common way is to drive the reflector by a device such as a motor, and although the method can make an operator feel comfortable, the device such as the motor is easy to break down along with the use of time, and is very troublesome when needing to be repaired or replaced, and the cost is high. Therefore, the connecting rod assembly 4 with high reliability is adopted to change the emergent direction of the light, and as long as the connecting rod is good in quality, the service life is very long. The reflector is composed of two reflectors 1, so that the purpose of changing the emergent direction of light can be achieved by respectively driving the two reflectors 1 to act. Specifically, the link assemblies 4 are disposed between the fixed ring 2 and the driving ring 3, so that the moving ends 42 thereof can also move between the fixed ring 2 and the driving ring 3 under the driving of the driving ring 3, and thus, the two reflectors 1 are respectively connected to the two moving ends 42, so that the positions of the reflectors 1 can be adjusted, and the two sets of link assemblies 4 synchronously operate to ensure the consistent light emitting angles. Description of the drawings: in fig. 1 and 2, a dotted line between the reflectors 1 is an indication that light is emitted, and a dotted line on the lamp cover 8 is a maximum range within which light can be emitted.

Referring to fig. 1, 2 and 4, each of the link assemblies 4 includes a first link 40 and a second link 41, the first link 40 is hinged to the second link 41, an end of the first link 40 away from the second link 41 is hinged to the driving ring 3, an end of the second link 41 away from the first link 40 is hinged to the fixing ring 2, and the moving end 42 is disposed at a position where the second link 41 is close to the fixing ring 2. In this embodiment, the connecting rod assembly 4 is two connecting rods, the two connecting rods are hinged and then hinged to the driving ring 3 and the fixing ring 2, so that when the driving ring 3 moves, the two connecting rods rotate due to the hinge, and then the moving end 42 is driven to rotate, and further the reflector 1 on the moving end 42 is driven to rotate, thereby achieving the purpose of changing the included angle between the two reflectors 1. Specifically, the first link 40 and the second link 41, the driving ring 3 and the first link 40, and the fixing ring 2 and the second link 41 are hinged by hinge shafts, the length direction of the hinge shafts is perpendicular to the vertical line direction between the driving ring 3 and the fixing ring 2, the hinge shaft between the fixing ring 2 and one of the second links 41 is a rotating shaft 43 around which one of the moving ends 42 rotates, the hinge shafts are used for the above-mentioned several hinges, and the rotating shaft 43 extends in the direction perpendicular to the paper, so that when the second link 41 rotates, the moving end 42 can rotate around the hinge shaft (i.e. the rotating shaft 43) thereof, thereby adjusting the angle of the reflective sheet 1. Of course, in addition to the rotating adjustment of the reflector 1, the reflector 1 may also be adjusted in a straight-up and straight-down manner, because the purpose of the reflector 1 is to block light, and light always emits along the edge of the reflector 1, and the rotating adjustment is also used to change the angle of light emission, and the straight-up and straight-down adjustment is also used to change the angle of light emission, specifically, two links may be fixedly connected, and the connection between two links and the adjacent driving ring 3 or fixing ring 2 may not be limited, and the hinge connection may also be fixed, for example, by driving the driving ring 3 to move up, the edge of the reflector 1 rises, and in the case of the same inclination angle, the angle of light emitted from the rising edge of the reflector 1 is larger than the angle emitted from the edge of the reflector 1 in the absence of the rising (the angle is relative to the vertical line, the included angle between the emergent ray and the vertical line after rising is larger than the included angle between the emergent ray and the vertical line which do not rise), thereby achieving the effect of adjusting the emergent angle of the ray.

As an optimization scheme of the embodiment of the utility model, please refer to fig. 1, fig. 2 and fig. 4, two one deck reflection of light unit is constituteed to reflection of light piece 1, reflection of light unit has two-layerly, two-layerly reflection of light unit is folded and is established, the first floor two of reflection of light unit the splice of reflection of light piece 1 and the second floor two of reflection of light unit the splice of reflection of light piece 1 staggers the setting. In this embodiment, when the above-mentioned one deck reflection of light unit's the condition of adoption, two reflection of light pieces 1 can appear the clearance when the expansion angle, and then the condition of light leak appears, consequently adopts two-layer reflection of light unit to fold to it sets up just to make their concatenation portion stagger to solve this problem. When two layers of reflecting units are arranged, two fixing rings 2 can be correspondingly configured, and the two fixing rings 2 are also horizontally arranged from top to bottom. Preferably, as shown in fig. 3, each of the reflectors 1 may be formed by splicing more than one, for example, two semicircular reflectors 1 may be combined to form a whole circle, which may now be divided into multiple segments like watermelon, if the reflector 1 of this form is provided, the splicing portions of the two segments need to be staggered when the two layers of light reflecting units are provided, for example, the middle bisector of one of the upper segments of the reflector 1 is located right above the splicing portion of the lower segment of the reflector 1, so that the gap can be blocked after the whole large reflector 1 is formed.

As an optimization scheme of the embodiment of the present invention, please refer to fig. 1, fig. 2 and fig. 4, the reflector further includes a driving assembly 5 for driving the driving ring 3 to move up and down.
