Description

Technical Field

[0001] The utility model relates to lamps and ceiling fans, and particularly to a lamp group module adopting trapezoidal connecting rods. Background Art

[0002] A ceiling fan is an electrical appliance that combines the functions of a chandelier and a ceiling fan. In addition to basic functions such as lighting and ventilation, most of them also have a decorative function. The two common types on the market are traditional straight - blade ceiling fans and invisible ceiling fans.

[0003] The light - emitting bodies of existing ceiling fans generally adopt integrally - formed shells. After forming, the shells are prone to deformation, and the light - emitting surface is very wide and thick. Moreover, the all - plastic integrally - formed ceiling fans are large in volume, with high packaging costs and large transportation costs.

[0004] For example, in a patent for a ceiling fan and a modular ceiling fan (publication number CN111677679A), a ceiling fan and a modular ceiling fan are disclosed. The ceiling fan includes: a volute, a fan assembly, a diffusion device, an air inlet, an air outlet, an air outlet passage, and a lighting assembly; the fan assembly includes a motor and a working wheel; the diffusion device includes a bearing wall for installing the fan assembly and a first diffusion mechanism arranged circumferentially around the working wheel on one side of the bearing wall; the air outlet passage is formed by the volute and the diffusion device; the light - diffusion plate of the lighting assembly covers the other side of the bearing wall; the air outlet is arranged on the outer periphery of the lighting assembly, and the orthographic projection of the light - emitting surface of the lighting assembly does not exceed the maximum boundary of the orthographic projection of the air outlet. Due to the light - diffusion plate covering the other side of the bearing wall, the air outlet being arranged on the outer periphery of the lighting assembly, and the orthographic projection of the light - emitting surface of the lighting assembly not exceeding the maximum boundary of the orthographic projection of the air outlet, the proportion of the light - emitting area of the ceiling fan is increased, and the luminous flux is increased. It can be seen from this technology that the modularization of the existing technology still stays at the level of simplifying installation, but the structure of the actual product is still large - sized, not convenient for transportation. And from the specific technical solution, we can see that the lamp and the fan affect each other. Due to the presence of the lamp, the ventilation holes of the fan can only adopt annular air outlet from the circumference of the lamp, and the air inlet holes are small, so the fan function of this technology is greatly weakened. Summary of the Utility Model

[0005] Technical Problem: The purpose of the present utility model is to solve the problems that the light - emitting part of the existing lamps and ceiling fans is not modularly designed, cannot be disassembled and transported, is not convenient for installation, and the functions of the fan and the lamp will affect each other.

[0006] Technical Solution: The present utility model adopts the following technical solutions:

[0007] A fan light lamp group module using trapezoidal connecting rods, comprising a mounting base and at least two light-emitting modules. Each light-emitting module includes a lower frame module, a waist bracket, and an upper frame module. The lower frame module, the waist bracket, and the upper frame module are connected end to end to form a closed frame. The upper frame module is connected to the mounting base, and the lower frame module is connected to the light-emitting frame.

[0008] As can be seen from the solution of this application, the lamp of this application is a ring-segment design. On the one hand, due to the segment design, each segment can exist independently, which is convenient for transportation. On the other hand, due to the combination, the combined ring-shaped light-emitting module is not only beautiful, but also leaves a mounting space for the fan. Further, the functions between the fan and the lamp do not affect each other, and the heat dissipation surfaces of both the fan and the lamp become larger, and the service life is longer.

[0009] Due to the adoption of a generally trapezoidal closed structure, after multiple light-emitting modules are assembled in cooperation, a structure with stable upper and lower frame modules can be formed, making the overall structure more stable.

[0010] Further, the light-emitting frame includes a light-emitting element and a light-transmitting cover; the light-emitting element is arranged inside the light-transmitting cover, and each lower frame module is fixed to the corresponding light-transmitting cover through the lower part, so that each lower frame module is connected to the corresponding light-emitting frame.

[0011] Further, buckle members are respectively arranged on the lower frame module and the light-transmitting cover, and are buckled to each other.

[0012] Further, the light-emitting frame, the lower frame module, and the upper frame module are all arc-shaped. All the light-emitting frames are on one concentric circle, all the upper frame modules are on one concentric circle, and all the lower frame modules are on one concentric circle.

[0013] Providing a mounting space for the fan, combined with the connection of all the frame modules to form an overall ring-shaped frame module. With the design that the mounting base is arranged above the center of the overall ring-shaped frame module, it can be seen that the ring-shaped space is all the reserved space for the fan, and the functions of the fan and the light-emitting module do not affect each other.

[0014] Further, a buckling part is arranged on the side of the waist bracket, and each light-emitting module is spliced with each other through the buckling of adjacent waist brackets.

[0015] Further, the lower frame module is provided with a wire hole, and the waist bracket is provided with a wire groove. The wire is arranged along the wire groove and passes through the wire hole to be electrically connected to the light-emitting element.

[0016] Further, the width of the light-transmitting cover is 12 - 18 mm, and the thickness is 22 - 28 mm. Among them, the width is the dimension of the light-transmitting cover along the horizontal radial direction, and the thickness is the dimension of the light-transmitting cover along the vertical direction.

[0017] The light-transmitting cover has a narrow side and a small thickness, increasing the light intensity.

[0018] The light-transmitting cover is made of polycarbonate, and the mounting base is made of polycarbonate mounting base.

[0019] Furthermore, the mounting base is circular, and there are a plurality of first card slots on the circumferential side wall that are adapted to a plurality of first engaging protrusions provided on the inner side wall of the upper frame module.

[0020] Through this design, the end engaging method of connecting the T-shaped connecting rod to the mounting base in the T-shaped connecting rod design is improved to a linear engagement between the annular integral body formed by the upper frame module and the mounting base, and the structure is more stable.

[0021] Furthermore, a fan module is also installed below the mounting base.

[0022] Beneficial effects: Compared with the prior art, the present utility model has the following advantages:

[0023] 1. The entire fan light is composed of two or more light-emitting modules spliced together, and a single light-emitting module is not easily deformed;

[0024] 2. The lamp is modular, simple to assemble, and has heat dissipation holes at the bottom, with better heat dissipation, ensuring the service life;

[0025] 3. The fan light can be modularly disassembled and assembled, simplifying and reducing the packaging, and facilitating transportation;

[0026] 4. The module frame has a narrow and thin light-emitting surface, increasing the light intensity, and the appearance is simple and beautiful. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present utility model will be further described below with reference to the drawings and embodiments.

[0036] Embodiment 1

[0037] As shown in the attached Figure 1 to the attached Figure 8 figures, a lamp group module using trapezoidal connecting rods includes a mounting base 1 and four light-emitting modules 2. Each light-emitting module 2 includes a curved lower frame module 3, and the central angle corresponding to each lower frame module 3 is 90°. The four lower frame modules 3 together form a 360° circumference. All the lower frame modules 3 are cooperatively connected to form an integral annular lower frame module. Above the center of the integral lower frame module, there is a mounting base 1. At both ends of the upper surface of each lower frame module 3 in the length direction, there are waist brackets extending towards the mounting base 1. Specifically, the waist brackets can be subdivided into a first connecting rod 4 and a second connecting rod 5. The ends of the first connecting rod 4 and the second connecting rod 5 far from the lower frame module 3 are provided with an upper frame module 6 with an arc shape adapted to the side surface of the mounting base 1. The upper frame module 6 is snap-fitted onto the mounting base 1 from top to bottom, so that multiple light-emitting modules cooperate to form a lamp group bracket with a stable structure. The lower surface of each lower frame module 3 is hollow to form a lower cavity. An LED light strip 7 is installed in the lower cavity of the lower frame module 3. A light-transmitting cover 8 is arranged below the LED light strip 7. The wiring terminals of the LED light strip 7 pass through the wire holes (not shown) of the lower frame module and the wire grooves 11 on the connecting rod and are connected to the power supply on the mounting base 1.

[0038] Snap-fastening members are respectively provided on the lower part of the frame 3 and the upper part of the light-transmitting cover 8, and are snap-fastened to each other.

[0039] The mounting base 1 is circular, and there are a plurality of first card slots 10 on the circumferential side wall adapted to a plurality of first engaging protrusions 9 provided on the inner side wall of the upper frame module 6.

[0040] The upper frame module 6, the first connecting rod 4, the second connecting rod 5 and the lower frame module 3 are integrally formed to form a light-emitting module having a generally trapezoidal shape.

[0041] The light-transmitting cover 8, the lower frame module 3 and the upper frame module 6 are all arc-shaped. All the light-transmitting covers 8 are on one concentric circle, all the upper frame modules 3 are on one concentric circle, and all the lower frame modules 6 are on one concentric circle.

[0042] The bottom surface of the lower cavity of the lower frame module 3 is provided with a second screw hole for the fixing bolt 12 to pass through and heat dissipation holes 13 evenly distributed along the extending direction of the bottom surface of the lower cavity.

[0043] The light-transmitting cover 8 is made of a polycarbonate light-transmitting cover, and the mounting base 1 is made of a polycarbonate mounting base.

[0044] The width of the light-transmitting cover 8 is 12 - 18 mm, such as 14.5 mm, 15 mm, 15.5 mm, etc., and the thickness is 22 - 28 mm, such as 24 mm, 25 mm, 26 mm, etc. Among them, the light-transmitting cover is arc-shaped, the width is the dimension of the light-transmitting cover along the horizontal radial direction, and the thickness is the dimension of the light-transmitting cover along the vertical direction.

[0045] Both the first connecting rod 4 and the second connecting rod 5 are connecting rods with wire grooves along the extending direction of the connecting rod length. The two connecting rods are respectively arranged at both ends of the lower frame module 3 in the extending direction of its length. Among them, the first connecting rod 4 does not exceed the extending direction of the length. The outer side surface of one of the wire groove walls of the wire groove is flush with the end surface of the lower frame module 3. The second connecting rod 5 extends beyond the length direction of the lower frame module 3, and the wire grooves of the first connecting rod 4 and the second connecting rod 5 are arranged in opposite directions up and down, so that the wire grooves of the two connecting rods can be cooperatively engaged.

[0046] On both sides of the wire groove wall of the second connecting rod 5, the inner side surface of one of the wire groove walls is flush with the end surface of the lower frame module 3, and the other wire groove wall extends out of the lower frame module 3 and the extending distance is the same as the distance between the wire groove walls on both sides of the first connecting rod 4.

[0047] On the wire groove wall of the first connecting rod 4 that is flush with the end surface of the lower frame module 3, there is a second card slot 15 for engaging with the second engaging protrusion 16 provided on the wire groove wall that extends out of the lower frame module 3 of the second connecting rod 5 of the adjacent light-emitting module. On the other wire groove wall of the first connecting rod 5, there is a third engaging protrusion 17 that can be engaged in the third card slot 14 provided on the wire groove wall of the second connecting rod 5 of the adjacent light-emitting module that does not extend out of the lower frame module 3.

[0048] Embodiment 2

[0049] On the basis of Embodiment 1, the number of the light-emitting modules 2 is modified to two. Accordingly, the central angle corresponding to the lower border module in each light-emitting module becomes 180°. After the two are combined, they jointly form a 360° circular ring structure. Specifically, the number of the light-emitting modules can be specifically modified according to requirements such as production, cost, and transportation. Without considering the transportation cost, surely the fewer the number of the light-emitting modules, the better, because the continuity of the light will be better (the thickness at the connection of adjacent light-transmitting covers doubles, affecting the light transmission amount, and due to the discontinuity of the light-emitting modules, the light will also be discontinuous), and the corresponding light intensity will also increase; the radius of the combined circular ring structure can also be increased to increase the ventilation volume of the fan and the lighting effect; and to control the cost, the number of the light-emitting modules can be increased to facilitate transportation and reduce the transportation cost.

[0050] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
