Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a purple LED effect light. Background Technology

[0002] Ultraviolet (UV) LED effect lights can excite the luminescent properties of fluorescent materials and are widely used in stages, nightclubs, and other settings. For example, props, costumes, or backgrounds coated with fluorescent powder exhibit a high-brightness fluorescent effect under UV light, enhancing visual impact. Moreover, when combined with other lights (such as laser lights), they can create special effects such as "time tunnels" and "light nets." They are commonly used in concerts, themed parties, and theatrical performances.

[0003] However, the existing purple LED effect lights have their angle diffusers fixed inside the lens assembly. The angle diffusers cannot be replaced or the entire lens assembly needs to be disassembled and reassembled to replace the angle diffusers. The operation process is cumbersome and complicated, and it is easy to damage the lens assembly.

[0004] In addition, due to the limitations of the heat dissipation structure, it is impossible to concentrate and quickly dissipate the heat from the light source, resulting in poor heat dissipation and affecting the lifespan of the lamp.

[0005] Therefore, in order to solve the above problems, it is urgent to develop a purple LED effect light that can quickly and conveniently replace the angle diffuser without the need for additional tools or lens assembly disassembly, thus improving the user experience; moreover, it can concentrate, efficiently and quickly dissipate the heat from the heat sink, improve the heat dissipation effect, and extend the life of the light fixture.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0036] like Figure 1-3As shown, a purple LED effect light includes a housing 1, a UV light source 2, a heat dissipation component 3, and a lens component 4. The UV light source 2 and the lens component 4 are arranged sequentially inside the housing 1 in the direction of light emission.

[0037] The lens assembly 4 includes a reflector 41 and a lens mounting plate 42. The lens mounting plate 42 has a lens mounting cavity 421 in the middle. The outer side of the lens mounting plate 42 is connected to the outer shell 1 through an external locking member.

[0038] One end of the reflector 41 is connected to the UV light source 2, and the other end is connected to the bottom outer surface of the lens mounting cavity 421;

[0039] The back of the UV light source 2 is connected to the heat dissipation component 3;

[0040] The lens mounting cavity 421 is provided with a light-transmitting hole. Inside the lens mounting cavity 421, a detachable light-emitting plate 5, an angle diffuser plate 6, and a spring coil 7 are arranged sequentially in the direction of light emission from the light source. The side wall of the lens mounting cavity 421 is provided with multiple through-holes 422.

[0041] The spring coil 7 is a non-closed circular elastic element. The two ends of the spring coil 7 are provided with gripping parts 71, and the non-gripping parts 71 of the spring coil 7 are provided with multiple protruding locking parts 72; the locking parts 72 are provided in a one-to-one correspondence with the limiting holes 422.

[0042] After the spring coil 7's locking part 72 is engaged with the limiting hole 422, it can prevent the light-emitting plate 5 and the angle diffuser 6 from disengaging from the lens mounting cavity 421.

[0043] In this embodiment, when installing the angle diffuser 6, the light-emitting plate 5 and the angle diffuser 6 are first placed in the lens mounting cavity 421 in sequence. Before placing the spring ring 7, the gripping part 71 is brought closer by external force to reduce the outer diameter of the spring ring 7. Then, the locking part 72 is aligned with the limiting hole 422 and the spring ring 7 is placed into the lens mounting cavity 421. After it is in place, the external force is released, and the spring ring 7 returns to its original outer diameter, so that the locking part 72 is locked into the limiting hole 422, thereby realizing the installation and fixation of the light-emitting plate 5 and the angle diffuser 6. Conversely, when replacing the angle diffuser 6, after removing the spring ring 7 in the above manner, the light-emitting plate 5 and the angle diffuser 6 will detach from the lens mounting cavity 421 under the action of gravity. This allows for quick and convenient replacement of the angle diffuser 6 without the need for additional tools or disassembly and reassembly of the lens assembly 4, greatly improving the user experience and preventing damage to the lens assembly 4.

[0044] In this embodiment, the external locking element is a locking screw.

[0045] Furthermore, such as Figure 1-3As shown, in order to achieve quick-release connection with the four-leaf light-blocking plate (not shown in the figure), the four-leaf light-blocking plate precisely limits the area of ​​light illumination; the outer periphery of the surface of the lens mounting plate 42 is provided with a connection structure 423 for connecting with the external four-leaf light-blocking plate.

[0046] Furthermore, such as Figure 1 , 2 As shown, the heat dissipation assembly 3 includes a support plate 31, a heat sink 32, a heat collection cover 33, and a fan 34;

[0047] A heat dissipation duct 10 is formed between the support plate 31 and the heat collection cover 33, and the direction of air outlet in the inner radial direction of the heat dissipation duct 10 gradually increases.

[0048] The heat sink 32 is disposed inside the heat dissipation duct 10 and is connected to the back of the UV light source 2.

[0049] The fan 34 is located at the outlet end of the heat dissipation duct 10;

[0050] An air outlet grille 1a is provided on the outer casing 1 at the position corresponding to the fan 34, and an air inlet grille 2a is provided on the side of the air inlet of the heat dissipation duct 10.

[0051] In this embodiment, by setting up a heat dissipation duct 10 with a gradually increasing inner diameter, consisting of a support plate 31 and a heat collection cover 33, the heat absorbed by the heat sink 32 is concentrated in the heat dissipation duct 10 and discharged by the fan 34, avoiding heat diffusion and retention in the outer casing 1 which would affect heat dissipation efficiency. This achieves concentrated and rapid heat dissipation, improves heat dissipation efficiency and effect, and extends the lifespan of the lamp.

[0052] Furthermore, such as Figure 1 , 2 As shown, a base plate 8 is provided at the end of the housing 1 away from the lens assembly 4, and a lamp hook assembly 9 is provided on the base plate 8.

[0053] Furthermore, such as Figure 1 , 2 As shown, in order to improve the convenient and quick connection between the lamp hook assembly 9 and the lamp body, the lamp hook assembly 9 includes a connecting seat 91 and a lamp hook body 92 connected to the connecting seat 91. The connecting seat 91 is quickly connected to the base plate 8.

[0054] Furthermore, to enhance safety and reduce the harm caused by ultraviolet radiation, the UV light source 2 emits ultraviolet light with a wavelength of 365-400nm.

[0055] In this embodiment, the duration of a single continuous irradiation is controlled within 20 minutes, and it can be used alternately with conventional lighting to completely avoid ultraviolet overload.

[0056] Furthermore, the spring coil 7 is a metallic elastic element or a non-metallic elastic element.

[0057] In this embodiment, the spring coil 7 may be made of stainless steel or glass fiber reinforced nylon.

[0058] Furthermore, such as Figure 3 As shown, in order to improve the color mixing effect of the emitted light spot, the surface of the light-emitting plate 5 is provided with a plurality of honeycomb compound eyes 51.

[0059] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
