Description

Technical Field

[0001] The utility model relates to the technical field of floodlights, in particular to a lighting assembly and a floodlight. Background Art

[0002] Floodlight is a common lighting device, usually used for outdoor landscape lighting or large-area indoor lighting. It is designed to evenly distribute light to the target area through optical devices on the lamp, such as lenses or reflectors, so as to achieve a wide range of lighting effects. The characteristic of floodlight is that it can produce a wide range of light and cover a wide area. It is often used to brighten buildings, landscapes or squares and other places to create a bright and comfortable atmosphere for the environment.

[0003] However, there are some problems with the current floodlights on the market during use. Due to the high temperature of the internal light source, the air pressure inside the lens increases, causing the lens made of PC material to soften in a high temperature environment, which in turn causes the light-emitting surface of the lens to bulge outward. In order to solve this problem, the existing technology often uses the method of screwing screws on the front of the lens to fix the lens. However, this operation requires opening a hole in the lens and adding an additional waterproof gasket to ensure waterproof performance, which not only increases the production and testing processes, but also affects the appearance of the product. Therefore, the current floodlights on the market have a difficult balance between fixing the lens and maintaining the appearance of the product during use. Utility Model Content

[0035] The present invention provides a lighting assembly 100 .

[0036] In the embodiment of the present utility model, Figures 1 to 7 As shown, the lighting assembly 100 includes a light board 1, a light-transmitting member 2 and a heat sink 3, the light board 1 having a light-emitting side 11 and a backlight side 12, the light board 1 being penetrated by a mounting hole 131; the light-transmitting member 2 being arranged on the light-emitting side 11, the light-transmitting member 2 having a low-beam side portion 21 close to the light board 1, a first connector 4 being arranged on the low-beam side portion 21 at a position corresponding to the mounting hole 131; the heat sink 3 being arranged on the backlight side 12, a second connector 5 being arranged on the heat sink 3 at a position corresponding to the mounting hole 131; one of the first connector 4 and the second connector 5 can pass through the mounting hole 131 and be detachably connected to the other.

[0037] Specifically, when the light board 1 is powered on, there is light on one side of the light board 1 and no light on the other side. Here, the side where the light is located is called the light-emitting side 11 of the light board 1, and the side without light is called the backlight side 12 of the light board 1.

[0038] The lighting assembly 100 of the technical solution of the present utility model is provided with a first connecting member 4 on the back side of the light-transmitting member 2 (the surface facing the light board 1), and a second connecting member 5 which can be detachably fixed to the first connecting member 4 is provided on the heat sink 3. Such a structure enables the light-transmitting member 2 and the heat sink 3 to be firmly connected, without the need to screw on the front side of the light-transmitting member 2 (the surface facing away from the light board 1), thereby avoiding the need to drill holes on the light-transmitting member 2, and also avoiding damage to the light-transmitting member 2 and additional waterproofing treatment, thereby simplifying the production process and maintaining the beautiful appearance of the product.

[0039] At the same time, after the first connecting member 4 and the second connecting member 5 are fixed together, the light-transmitting member 2 can be restricted from moving in a direction away from the lamp board 1, which can prevent the light-transmitting member 2 from protruding in a direction away from the lamp board 1. In addition, since one of the first connecting member 4 and the second connecting member 5 passes through the mounting hole 131 during the connection process, the lamp board 1 can be effectively limited to prevent the lamp board 1 from moving arbitrarily in the diameter direction of the mounting hole.

[0040] Finally, the presence of the mounting hole 131 also facilitates the movement of cold gas from the heat sink 3 to the light-transmitting member 2, thereby lowering the temperature of the light-transmitting member 2 and preventing it from softening due to heat. Heat can also be transferred between the first connecting member 4 and the second connecting member, thus effectively lowering the temperature of the light-transmitting member 2.

[0041] In specific implementation, in some embodiments, one of the first connecting member 4 and the second connecting member 5 can be designed to have an elastic structure, and they are clamped together by elastic force during installation. This method does not require additional tools and simplifies the installation process.

[0042] In other embodiments, the first connecting member 4 and the second connecting member 5 can be designed as a plug and a slot respectively, and the connection is achieved by inserting the plug into the slot. This method is simple and convenient, and is suitable for quick installation and removal.

[0043] In some other embodiments, the first connector 4 and the second connector 5 can be designed to be made of magnetic materials, and they are attracted together by magnetic force during installation to achieve connection. Since there are many embodiments of the first connector 4 and the second connector 5, they are not listed here one by one.

[0044] Specifically, see Figure 4 and Figure 6 The light board 1 includes a board body 13 and a plurality of light-emitting parts 14 disposed on the board body 13, and the mounting through hole 131 is disposed on the board body 13;

[0045] The low beam side portion 21 is provided with a plurality of light guide portions 22 corresponding one to one with the plurality of light emitting portions 14;

[0046] The height of the first connecting member 4 protruding from the surface of the low beam side portion 21 is set to be greater than the height of the light guide portion 22 protruding from the surface of the low beam side portion 21. The first connecting member 4 passes through the mounting hole 131 and is connected to the second connecting member 5 on the backlight side 12 to shorten the interval between the light guide portion 22 and the corresponding light-emitting portion 14.

[0047] Specifically explained, the light emitting portion 14 may be an LED lamp bead disposed on the board body 13 , and the light guiding portion 22 may be a light guiding column or a bowl-cup structure.

[0048] It is not difficult to understand that by adding the light-guiding portion 22, the light emitted by the corresponding light-emitting portion 14 can be more effectively guided, so that the light of each light-emitting portion 14 can be concentratedly irradiated to the target area, thereby improving the lighting effect of the light.

[0049] By assembling the first connecting member 4 and the second connecting member 5 on the backlight side 12, compared with the method of assembling the first connecting member 4 and the second connecting member 5 on the light-emitting side 11, the design of the present application can more effectively shorten the interval between the light-guiding portion 22 and the light-emitting portion 14, reduce the loss of light during transmission, improve the optical performance of the lighting assembly 100, and make the light more uniform and stable.

[0050] Preferably, the light-guiding portion 22 is a bowl cup, and an opening is provided on the end of the bowl cup near the plate body 13. After the first connecting member 4 and the second connecting member 5 are assembled, the light-emitting portion 14 can extend into the bowl cup through the corresponding opening, or the light-emitting portion 14 is just in the opening.

[0051] See also Figure 4 The heat sink 3 includes a heat dissipation side portion 31 , the heat dissipation side portion 31 abuts against the lamp board 1 , an avoidance groove 32 is provided on the heat dissipation side portion 31 at a position corresponding to the mounting through hole 131 , and the second connecting member 5 is arranged in the avoidance groove 32 .

[0052] The avoidance groove 32 is designed to accommodate the second connector 5, avoiding the second connector 5 being arranged between the heat dissipation side portion 31 and the lamp board 1, thereby ensuring the effective abutment between the heat dissipation side portion 31 and the lamp board 1 without being interfered by the second connector 5. The heat dissipation side portion 31 is an important part of the heat dissipation element 3, which is designed to abut against the lamp board 1 to ensure effective heat dissipation conduction. During the heat transfer process, the heat of the lamp board 1 is directly transferred to the heat dissipation element 3 without passing through the air, thereby improving the heat dissipation efficiency, effectively reducing the operating temperature of the lamp board 1, and extending the service life of the lamp board 1.

[0053] A first threaded hole is provided on the bottom wall of the avoidance groove 32, and a second threaded hole is provided on the second connecting member 5. The lighting assembly 100 includes a first fastener 6, and the first fastener 6 can be threadedly connected to the second threaded hole and the first threaded hole respectively to fix the second connecting member 5 in the avoidance groove 32.

[0054] In a specific implementation, the first fastener 6 can be a bolt, a screw, a fixing pin or other structures, and no specific limitation is made here.

[0055] It can be understood that the introduction of the first fastener 6 enables the second connecting member 5 to be assembled and disassembled independently of the heat sink 3. This modular design helps to quickly replace or upgrade specific components of the floodlight, thereby reducing maintenance and update costs.

[0056] A ventilation gap is formed between the portion of the first connecting member 4 located in the mounting hole 131 and the peripheral wall of the mounting hole 131 .

[0057] It can be understood that the ventilation gap provides a channel from the heat sink 3 to the light-transmitting member 2, so that the cold gas around the heat sink 3 can move to the light-transmitting member 2 through the ventilation gap, which helps to reduce the operating temperature of the light-transmitting member 2 and the side of the lamp panel 1 facing away from the heat sink 3.

[0058] The ventilation gap can also reduce the humidity and the possibility of condensation inside the floodlight. Through the ventilation gap, air can circulate, reducing the humid environment inside the floodlight, effectively preventing the influence of condensation on the internal components of the floodlight, and improving the stability and reliability of the lamp.

[0059] The second connecting member 5 comprises two elastic arms 551 extending in parallel, a clamping space 52 is formed between the two elastic arms 551, and one of the two elastic arms 551 can move in a direction away from the other elastic arm 551;

[0060] The first connecting member 4 includes a clamping portion 421 , and the clamping portion 421 extends into the corresponding clamping space 52 and presses the two elastic arms 551 .

[0061] The two elastic arms 551 of the second connecting member 5 have a certain elasticity, and one of the elastic arms 551 can move in a direction away from the other elastic arm 551 . This design allows the second connecting member 5 to adapt to first connecting members 4 of various sizes or shapes.

[0062] The clamping portion 421 of the first connector 4 extends into the corresponding clamping space 52 and squeezes the two elastic arms 551 to form a fixed connection. This structural design makes the installation process easier, does not require additional tools or complicated operations, helps to improve the assembly efficiency of the components, and reduces the assembly cost.

[0063] The design of the elastic arm 551 can buffer and absorb the vibration and impact generated by the lamp panel 1 and the light-transmitting member 2 during use, thereby reducing the degree of vibration transmission to other components and reducing the generation of noise.

[0064] Each of the elastic arms 551 includes a connected straight arm 511 and a bent arm 512, each of the straight arms 511 is fixed on the heat sink 3, the two straight arms 511 extend in parallel, the two bent arms 512 extend in parallel, the minimum spacing between the two bent arms 512 is smaller than the minimum spacing between the two straight arms 511, and the minimum spacing between the two bent arms 512 is smaller than the maximum diameter setting of the clamping portion 421.

[0065] It can be understood that the minimum spacing between the bending arms 512 is smaller than the maximum diameter setting of the clamping portion 421, ensuring that the clamping portion 421 can be firmly clamped between the two bending arms 512 during connection, and preventing the clamping portion 421 from easily escaping from between the two elastic arms 551.

[0066] The first connecting member 4 includes a column 41 and a second fastener 42. The column 41 is fixed to the low beam side portion 21. A third threaded hole is provided on the column 41. The second fastener 42 is threadedly connected to the third threaded hole. At least part of the structure of the second fastener 42 is exposed outside the column 41 to form the clamping portion 421.

[0067] In a specific implementation, the second fastener 42 can be a bolt, a screw, a fixing pin or other structures, which are not specifically limited here.

[0068] The column 41 is in close contact with the low beam side portion 21 , and can effectively conduct heat from part of the light-transmitting element 2 , thus helping the heat dissipating element 3 to dissipate heat quickly.

[0069] By adjusting the length of the second fastener 42, or adjusting the installation depth of the second fastener 42 on the column 41, the height of the first connecting member 4 protruding from the low beam side portion 21 can be adjusted, which is convenient for controlling the depth of the first connecting member 4 inserted into the avoidance groove 32, and also convenient for adjusting the interval between the light-emitting portion 14 and the light-guiding portion 22.

[0070] The end surface of the second fastener 42 away from the low beam side portion 21 is arranged in a convex arc surface. The convex arc surface is conducive to reducing the friction and resistance between the elastic arm 551, so that the second fastener 42 can be more easily inserted into the deep of the clamping space 52, improving the convenience of operation.

[0071] The rounded design of the arc surface can reduce damage to the elastic arm 551 and other components during installation. Compared with sharp corners, the rounded convex surface is gentler, reducing scratches or wear on the surface of the elastic arm 551 and increasing the service life of the components.

[0072] The utility model also provides a floodlight, which includes a lighting assembly 100. The specific structure of the lighting assembly 100 refers to the above embodiments. Since the floodlight adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0073] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
