Description

Technical Field

[0001] The utility model relates to a lamp, in particular to a reflective light lamp with adjustable polarization angle. Background Art

[0002] Lamps are widely used. Take wall washers as an example. The light emitted by the lamps is not used as the main light in the room for lighting. Instead, the light is projected onto light receptors such as walls to achieve a wall washing function. This type of lamp is generally fixed on a vertical wall or ceiling.

[0003] The existing wall washer lamp mainly includes a lamp holder, a base and an articulated arm. The lamp holder is connected to the base through the articulated arm. The base is fixed on a vertical wall or ceiling. After the lamp is installed, the illumination angle of the lamp holder is adjusted through the articulated arm so that the light can meet the use requirements, for example, the angle of the lamp holder is adjusted to illuminate the entire wall. The lamp of this structure has the following defects: ① Due to the existence of the articulated arm, the articulated arm is exposed, resulting in a large outer dimension of the entire lamp. For some narrow spaces (such as ceiling troughs), there is not enough space to install and adjust the lamp; ② Since the lamp holder includes components such as an aluminum heat sink and is heavy, the articulated arm, as a cantilever structure, may cause the articulated position locking to fail, causing the lamp holder to deflect downward under its own weight, etc., thereby causing the illumination angle of the lamp to be uncontrollably offset and unable to meet the wall washer requirements; ③ After the articulated arm of this lamp is exposed, it is difficult to improve the appearance of the lamp, and it cannot match the existing high-quality decoration design style. Utility Model Content

[0031] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments described below can be combined with each other arbitrarily without conflict.

[0032] Many different implementations or examples are provided below to implement the structure of the present utility model.

[0033] See also Figure 1-Figure 11 The embodiment of the utility model is a reflective light fixture with adjustable polarization angle, including a heat dissipation shell 1, which is generally made of aluminum. A light source board 2 and a reflective cup 3 are arranged in the heat dissipation shell 1. A slot 11 is arranged in the heat dissipation shell 1, and the light source board 2 is plugged into the slot 11 for easy installation. A light outlet 12 is arranged on the light emitting side of the heat dissipation shell 1, and the light outlet 12 is located above the light source board 2, so that the light source board 2 is designed to be hidden, and there is no need to set a decorative plate on the light source board 2 to cover the light source board 2, thereby reducing the number of spare parts and reducing costs. A lamp bead 21 is arranged on the light source board 2, and the lamp bead 21 is located above the reflective cup 3 (with Fig.11 The light emitted by the lamp bead 21 is first emitted downward toward the reflector cup 3, and then emitted from the light outlet 12 after being reflected upward by the reflector cup 3. The reflector cup may include a plurality of independent circular reflector cups, that is, the reflector cup is a split reflector cup; in this embodiment, see Figure 8 As shown, the reflector is an integrated reflector, which has multiple independent circular reflectors, making the assembly of the reflector simpler and more reliable. The integrated reflector is in the shape of a strip, and the lamp can have one or more integrated reflectors according to the length requirements. It also includes a motor 4 and a drive assembly connected to the motor 4, and the drive assembly is connected to the reflector 3. When the motor is working, the drive assembly can drive the reflector 3 to move, so that the relative position of the reflector 3 and the lamp bead 21 changes, so as to adjust the reflector 3 and the lamp bead 21. Fig.11 Taking the angle shown as an example, the driving assembly can drive the reflective cup 3 to translate left and right; it can be understood that the light source board 2 can also be fixed to the heat dissipation housing 1 by means of screws or the like.

[0034] See Figure 5 , Figure 7 and Figure 9-11 As shown, in some embodiments of the utility model, the reflective cup 3 is connected and fixed on the bracket 5, and a slide groove 13 is provided in the heat dissipation housing 1. The bracket 5 is driven by the driving component, and the bracket 5 can slide in the slide groove 13 to drive the reflective cup 3 thereon to move. That is, the driving component can directly connect and drive the reflective cup 3 to move, and can also drive the reflective cup 3 through the bracket 5. A card slot 51 is provided on the bracket 5, and the edge of the reflective cup 3 is inserted into the card slot 51, so that the reflective cup 3 and the bracket 5 can be pre-assembled, and then installed in the heat dissipation housing 1 after pre-assembly, thereby improving assembly efficiency. The bracket 5 is driven by the driving component to slide in the slide groove 13, so that the movement of the bracket 5 is more stable and reliable, and the accurate control of the movement of the reflective cup 3 is improved.

[0035] See Figure 3-Figure 6 , Fig.11 As shown, in some embodiments of the present invention, the driving assembly includes a rack 61 and a gear set 62, the rack 61 is connected and fixed to the bracket 5 by means of screws or adhesives, and the gear set 62 is connected to the motor 4 and meshes with the rack 61. Fig.11 Taking the structure shown as an example, the user gives a control panel command (such as a remote control) to the lamp, the motor 4 rotates, causing the gear set 62 to rotate, the gear set 62 drives the rack 61 to move left and right, and the rack 61 drives the bracket 5 to slide left and right in the slide groove 13, thereby easily realizing the position adjustment of the reflective cup 3, and finally realizing the adjustment of the angle of the light reflected by the reflective cup 3.

[0036] See Figure 3 , Figure 4As shown, in some embodiments of the utility model, a vertical plate 7 is provided on the heat dissipation shell 1, the gear set 62 is connected and fixed to the vertical plate 7, the vertical plate 7 is covered with an end cover 8, and the motor 4 is arranged on the end cover 8. Through the arrangement of the vertical plate 7 and the end cover 8, the gear set 62 and other components are hidden, thereby improving the aesthetics of the lamp. Moreover, since the gear set 62 and the motor 4 are arranged at the end of the lamp, only the length of the lamp is increased without increasing the width and height of the lamp, thereby realizing the miniaturization and compactness of the lamp, so that the lamp can be installed in a narrow space.

[0037] In other embodiments of the present invention, the driving assembly includes a worm gear and a worm, the worm gear is connected and fixed to the reflective cup 3 or the bracket 5, the worm gear is meshed with the worm gear, and the worm gear is connected to the motor 4. In other embodiments of the present invention, the driving assembly includes a lever, the lever is driven by the motor 4, and the lever moves the reflective cup or the bracket 5. The worm gear structure, the lever structure, etc. are common structures, which are easy to understand and implement by those skilled in the art, so they are not shown in drawings or elaborated.

[0038] See Fig. 9 and Fig.11 As shown, in some embodiments of the utility model, the lamp is a linear lamp, and a light baffle 14 is provided on one side of the lamp in the width direction. The light baffle 14 can be integrally formed on the heat dissipation shell 1, and the light baffle 14 is used to block light to prevent the light emitted by the lamp from directly entering the human eye, and the light baffle 14 also has the function of reflecting light, so that part of the light reflected by the reflective cup 3 is reflected by the light baffle 14 and then emitted to the wall, thereby improving the lighting effect; in other embodiments, the lamp is a circular spotlight.

[0039] See Figure 2 As shown, in some embodiments of the utility model, the linear light has two ends in the length direction, and the two ends are provided with the driving assembly. Two sets of driving assemblies are provided, so that both ends of the reflective cup or the bracket (if any) are driven by the driving assembly, so that the force is more uniform, and the stuck and offset phenomenon that may be caused by the force on one end is avoided, so that the movement of the reflective cup or the bracket is smoother, and the movement of all reflective cups 3 is ensured to be synchronous, and finally the polarization angle of the light of the lamp at different light outlets is ensured to be consistent.

[0040] From the above structural analysis, it can be known that the embodiment of the utility model arranges a light source board 2 and a reflective cup 3 in a heat dissipation housing 1, and a lamp bead 21 is arranged on the light source board 2, and the lamp bead 21 is located above the reflective cup 3, so that the light emitted by the lamp bead 21 is first emitted to the reflective cup 3, and then emitted outward after being reflected by the reflective cup 3. By arranging a motor 4 and a driving component connected to the motor 4, the driving component is connected to the reflective cup 3, so that when the motor 4 is working, the driving component can drive the reflective cup 3 to move, and the relative position of the reflective cup 3 and the lamp bead 21 changes. Since the light of the lamp bead 21 is emitted to the reflective cup 3, the change in the position of the reflective cup 3 will change the angle of the reflected light. This structure makes it unnecessary to adjust the lamp after it is installed on the wall or ceiling. The polarization angle adjustment is achieved not by adjusting the position of the reflective cup inside, but by adjusting the position of the reflective cup inside, so that the polarization angle adjustment of the lamp is easily achieved, and the articulated arm and other structures in the prior art are abandoned. Since there is no exposed articulated arm and a lamp holder independently connected to the articulated arm, there is no problem of locking failure at the hinge and the lamp holder sagging due to its own weight. After the polarization angle of the lamp described in the embodiment of the utility model is adjusted to the right position, it can be ensured that the lamp always maintains the set polarization emission angle. Compared with the existing lamp composed of a base, an articulated arm and a lamp holder, the overall size is significantly improved, so that the lamp can be installed in a narrow space, and the polarization angle can still be achieved after installation. Moreover, the appearance of such a lamp is easier to improve.

[0041] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
