Description

Technical Field

[0001] This utility model relates to the field of decorative lighting technology, specifically a curtain wall decorative light. Background Technology

[0002] After installation, decorative curtain wall lights typically require precise fine-tuning of the illumination angle to achieve optimal lighting effects and avoid light pollution, ensuring that the beam is accurately projected onto the designated area. Therefore, the ability to adjust the projection direction of the light fixture is one of its key performance characteristics.

[0003] Currently available curtain wall lights have significant shortcomings in angle adjustment. Most products use simple bolt-arc hole adjustment mechanisms or hinge structures. Specifically, adjustment requires first loosening the locking bolts, then manually moving the light body to the desired angle, and finally retightening the bolts to fix it. This method has revealed many drawbacks in practical applications:

[0004] First, the adjustment process is cumbersome and extremely inconvenient. Operators need to simultaneously ensure the angle is aligned and the bolts are tightened, which is especially difficult in high-altitude working environments.

[0005] Secondly, and more importantly, this method of locking by friction is unreliable. After the lamps have been subjected to wind loads, vibrations, and thermal expansion and contraction caused by temperature changes for a long time, the locking bolts are very likely to loosen, causing the originally adjusted illumination angle to shift or even change. It cannot maintain long-term stability. Once the angle changes, it will not only affect the expected decorative effect, but may also cause unnecessary light spillage and light pollution.

[0006] Furthermore, some designs attempt to enhance stability by adding extra fasteners, but this only further increases the complexity of adjustment and operation time. Utility Model Content

[0007] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a decorative lamp with adjustable light source orientation to ensure excellent lighting effect.

[0008] The technical solution adopted by this utility model to achieve the above objectives is as follows: a curtain wall decorative light, including a lamp housing, a light source board, a lamp shade, and an adjustable mounting base. The lamp housing has a light source cavity inside, and the light source board is snapped into the light source cavity. The top of the lamp housing has an open structure, and the lamp shade is snapped into the top of the lamp housing. The bottom of the lamp housing is snapped into a mounting bracket, and the mounting bracket is fixedly connected to the adjustable mounting base.

[0009] In the above technical solution, the light source cavity has the following structural arrangement:

[0010] A reflective inclined surface A is provided on one side of the light source cavity, and a reflective inclined surface B is provided on the light source cavity corresponding to the reflective inclined surface A. The height of the reflective inclined surface A is greater than the height of the reflective inclined surface B, and the tilt angle of the reflective inclined surface A is greater than the tilt angle of the reflective inclined surface B.

[0011] Furthermore, the lampshade is provided with a light-mixing inclined surface, and the reflective inclined surface A faces the light-mixing inclined surface.

[0012] In the above technical solution, the light source board includes a fiberglass board and a light strip fixedly connected to the fiberglass board, and the fiberglass board is snapped into the light source cavity.

[0013] Furthermore, to ensure uniform light, two rows of LED beads are arranged alternately on the LED strip, and a flexible convex cover is fixedly connected to each group of LED beads to eliminate stray light.

[0014] In the above technical solution, to prevent it from falling, multiple sets of anti-fall ropes are fixedly connected to the bottom of the lamp housing.

[0015] In the above technical solution, the structure of the adjusting mounting base is as follows:

[0016] The adjustable mounting base includes a mounting frame, an adjusting frame, and an adjusting component. The adjusting frame is rotatably connected to the mounting frame, and the mounting bracket is fixedly connected to the adjusting frame. The adjusting component is provided on the mounting frame in conjunction with the rotating part of the adjusting frame.

[0017] In the above technical solution, the structure of the adjustment component is as follows:

[0018] The adjustment assembly includes a worm gear, a worm wheel, and a knob. A rotating seat is fixedly connected to the mounting bracket, and a rotating shaft is fixedly connected to the adjustment bracket. The rotating shaft is rotatably connected to the rotating seat, and the worm wheel is fixedly connected to one end of the rotating shaft. The worm gear is rotatably connected to the mounting bracket, and the worm gear meshes with the worm wheel. The knob is fixedly connected to the end of the worm gear.

[0019] The beneficial effects of this utility model are:

[0020] 1. The orientation of the light source can be adjusted by adjusting the mounting base. That is, by turning the knob, the worm gear drives the worm wheel to rotate, which in turn causes the adjustment bracket to rotate the lamp housing, thereby precisely adjusting the beam direction and improving the lighting effect. Moreover, the worm gear transmission has a natural self-locking property. After adjustment, the angle will be completely locked without external force driving the knob, and will not shift due to the weight of the lamp or wind load, ensuring the long-term stability of the projection angle.

[0021] 2. The reflective ramps A and B work together to more effectively collect and reflect the side light emitted by the light source plate, reducing light loss within the cavity and improving light output efficiency. At the same time, the different heights and angles of the two ramps form an asymmetrical optical system, which can better guide the light in the desired direction (such as downward or outward) and premix it within the cavity, laying the foundation for subsequent light mixing and effectively avoiding obvious light spots or dark areas. The light mixing ramp on the lampshade works in conjunction with the reflective ramp A to perform secondary processing and mixing of the light, ultimately making the emitted light more uniform and softer, achieving a high-end visual effect of seeing the light but not the lamp, and greatly improving the lighting quality.

[0022] 3. The two rows of LED beads on the light strip are arranged in an alternating pattern, which increases the density of the light source distribution, reduces dark areas from the source, and makes the lighting more uniform. The flexible convex cover of each LED bead can effectively constrain and diffuse the light, eliminate glare and dazzling stray light, make the light spot transition smooth, and provide extremely high visual comfort.

[0023] 4. Multiple sets of fall arresting ropes are designed and directly connected to the curtain wall structure. Even if the installation buckle fails unexpectedly, it can firmly hold the light body, completely eliminating the risk of falling objects from heights. This is crucial for high-altitude applications of curtain walls. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4 A curtain wall decorative light mainly includes a lamp housing 100, a light source board 200, a lamp shade 300, and an adjustable mounting base 400. The lamp housing 100 is an overall long strip aluminum profile structure, and its interior is provided with a light source cavity 101 that runs through the entire length of the lamp body. The cross-section of the light source cavity 101 is asymmetrical. Specifically, one inner wall of the light source cavity 101 is provided with a reflective inclined surface A102, and the opposite inner wall is provided with a reflective inclined surface B103. The vertical height of the reflective inclined surface A102 is greater than the vertical height of the reflective inclined surface B103, and the tilt angle of the reflective inclined surface A102 relative to the horizontal plane is also greater than the tilt angle of the reflective inclined surface B103. This unique asymmetrical design aims to guide and mix light more effectively. The top of the lamp housing 100 is an open structure for mounting the lamp shade 300, and its bottom is provided with a snap-fit ​​structure for connecting the mounting bracket 500.

[0031] The light source board 200 is fixedly installed in the light source cavity 101 by a snap-fit ​​method. The light source board 200 is composed of a fiberglass substrate 201 and an LED light strip 202 fixed thereon. Two rows of LED beads 2021 are arranged alternately on the LED light strip 202. This arrangement is intended to increase the light source distribution density and avoid dark areas. The outer surface of each LED bead 2021 is encapsulated with a flexible convex cover 2022. The convex cover can diffuse the light emitted by the LED bead initially, effectively eliminating stray light and glare.

[0032] The lampshade 300 is made of translucent PC material and is fixed to the opening at the top of the lamp housing 100 by the clips on both sides, thereby sealing the light source cavity 101. A light mixing slope 301 is formed on the side of the lampshade 300 facing the light source cavity 101. The light mixing slope 301 is set opposite to the reflective slope A102 inside the light source cavity 101 of the lamp housing 100. It is used to receive the light reflected by the reflective slope A102 and mix and diffuse it a second time, so that the light is emitted evenly and softly, achieving a high-quality light output effect.

[0033] The bottom of the lamp housing 100 is fixedly connected with multiple stainless steel fall arrest ropes 600 by screws. The other end of these fall arrest ropes 600 is designed to be connected to the main structure of the building curtain wall to form an independent safety guarantee to prevent the lamp from falling in extreme circumstances.

[0034] The adjusting mounting base 400 is used to fix the entire lamp body and adjust it to a preset angle. It mainly includes a mounting frame 401, an adjusting frame 402, and an adjusting component 403. The mounting frame 401 is fixed to the supporting structure of the building curtain wall by bolts. The adjusting frame 402 is rotatably connected to the rotating seat 4032 on the mounting frame 401 through a rotating shaft 4031. The lamp housing 100 is fixedly connected to the adjusting frame 402 through the mounting bracket 500 at its bottom, so that the lamp body can rotate relative to the mounting frame 401 together with the adjusting frame 402.

[0035] The adjustment assembly 403 is used to drive and lock the rotation of the adjustment frame 402. Its core is a worm gear mechanism. Specifically, a worm gear 4033 is fixedly installed at one end of the rotating shaft 4031, and the worm 4034 is rotatably installed on the mounting frame 401 through a bearing seat. The teeth of the worm 4034 are precisely meshed with the worm gear 4033. The bottom end of the worm 4034 extends out and is fixedly connected to a knob 4035 that can be operated manually.

[0036] When the illumination angle of the lamp needs to be adjusted, the operator only needs to rotate the knob 4035. The rotation of the knob 4035 drives the worm gear 4034 to rotate, which in turn drives the meshing worm wheel 4033 to rotate. The worm wheel 4033 then drives the rotating shaft 4031 and the adjusting bracket 402, which are fixed together, to rotate slowly and smoothly, thereby achieving stepless and precise adjustment of the lamp's pitch angle. Because the worm gear 4033 and worm wheel 4034 transmission mechanism has an inherent self-locking characteristic, that is, only the worm gear 4034 can drive the worm wheel 4033, and the worm wheel 4033 cannot drive the worm gear 4034 in the opposite direction, once the knob 4035 is stopped, the lamp's angle is immediately locked at the current position. This structure ensures that the lamp will not have an unexpected angle deviation under the action of external forces such as wind load and vibration, thus guaranteeing the long-term stability of the lighting effect.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
