[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 6 This invention describes an LED luminaire with adjustable color temperature according to an embodiment of the present invention.

[0033] like Figures 1 to 5 As shown, the LED lamp with adjustable color temperature according to an embodiment of the present invention includes a lamp housing 100 and a light source assembly 200. The lamp housing 100 is provided with a mounting platform, and the light source assembly 200 is disposed on the mounting platform. The light source assembly 200 includes an LED module 300, a color temperature filter module 400, and a lens module 500. The LED module 300 includes an LED base 310 disposed on the mounting platform and an LED chip 320 disposed on the LED base 310 or the mounting platform. The color temperature filter module 400 includes a color temperature filter base 410 and a color temperature lens 420 disposed on the color temperature filter base 410. The color temperature filter base 410 is detachably mounted to the LED base 310 through a first rotating snap-fit ​​mechanism, and the lens module 500 is detachably mounted to the color temperature filter base 410.

[0034] Since the color temperature filter base 410 can be detachably installed onto the LED base 310, the color temperature of the lamp can be changed by replacing different color temperature filter modules 400 on the same specification LED module 300, which meets the assembly requirements of lamps with multiple color temperatures, reduces production costs, and adopts a rotating snap-fit ​​mechanism for disassembly and assembly, making replacement and assembly simple and quick.

[0035] Specifically, during the production process, basic LED chips of the same specifications (such as blue LED chips) can be purchased uniformly. By configuring color temperature filter modules 400 with different emission color temperatures, the assembly requirements of various color temperature lamps can be met. Color temperature lenses 420 can achieve different color temperature display effects by configuring phosphors with different contents or specifications. Color temperature lenses 420 are independent components, and their production difficulty and production cost are far lower than those of LED chips that directly encapsulate color-producing phosphors. Therefore, it can effectively reduce the manufacturing cost of lamps. In addition, the color temperature filter module 400 adopts a rotating snap-fit ​​mechanism for disassembly and assembly, which is convenient and quick. After the assembly is completed, the color temperature can also be changed as needed to meet different usage requirements.

[0036] In some embodiments of this utility model, the lens module 500 is detachably installed on the color temperature filter base 410, so that different light effects of the lamp can be achieved by replacing the lens module 500 of different specifications during the production and assembly process, so as to meet different usage requirements.

[0037] Specifically, the LED module 300, color temperature filter module 400, and lens module 500 can be disassembled and assembled sequentially along the light output direction, which facilitates the overall assembly of the lamp. The assembly process is simple and efficient.

[0038] In some embodiments of this utility model, the LED base 310 is fixed to the mounting platform, and the LED chip 320 can be directly mounted and fixed to the mounting platform, or the LED chip 320 is mounted on the LED base 310 and mounted to the mounting platform through the LED base 310.

[0039] In some embodiments of this utility model, the LED base 310 is mounted to the mounting platform by a screw mechanism or a clamping mechanism.

[0040] In some embodiments of this utility model, the first rotating snap-fit ​​mechanism includes a first snap-fit ​​part 411 and a first snap-fit ​​groove 311 into which the first snap-fit ​​part 411 can be rotatably snapped. One of the first snap-fit ​​part 411 and the first snap-fit ​​groove 311 is provided on the color temperature filter base 410, and the other is provided on the LED base 310. Through the rotatable snap-fit ​​cooperation between the first snap-fit ​​part 411 and the first snap-fit ​​groove 311, the color temperature filter module 400 can be detachably installed.

[0041] like Figure 4 and Figure 5As shown, in some embodiments of this utility model, the first snap-fit ​​part 411 is provided on the color temperature filter base 410, and the first screw-fit groove 311 is provided on the LED base 310. The first snap-fit ​​part 411 extends downward and has an L-shaped structure. The first screw-fit groove 311 is an arc groove, and a first baffle 312 is provided at one end of the first screw-fit groove 311. The first snap-fit ​​part 411 can be inserted into the first screw-fit groove 311 from top to bottom. After the color temperature filter base 410 is rotated relative to the LED base 310 by a set angle, the first snap-fit ​​part 411 and the first baffle 312 snap-fit ​​together, thereby realizing the detachable installation of the color temperature filter module 400.

[0042] Specifically, the side of the first baffle 312 has a notch for the first snap-fit ​​part 411 to be inserted into the first screw-fit groove 311 from top to bottom. The bottom of the first baffle 312 forms a roughly horizontal first screw-fit groove 311. The lower end of the first snap-fit ​​part 411 is inserted into one end of the first screw-fit groove 311 from top to bottom through the notch. Then, by rotating the color temperature filter base 410, the first snap-fit ​​part 411 is snapped into the bottom of the first baffle 312, thereby completing the detachable installation of the color temperature filter module 400.

[0043] It is conceivable that in some embodiments of this utility model, the first snap-fit ​​part 411 may be an inverted T-shaped structure, the first screw-fit groove 311 may be an arc-shaped groove with an inverted T-shaped cross section, and an opening is provided above one end of the first screw-fit groove 311 for the first snap-fit ​​part 411 to be inserted. After the first snap-fit ​​part 411 is inserted into the first screw-fit groove 311, the color temperature filter base 410 is rotated so that the first snap-fit ​​part 411 is snapped into the first screw-fit groove 311, thereby realizing the detachable installation of the color temperature filter module 400.

[0044] It is understood that in some embodiments of the present invention, the first rotating snap-fit ​​mechanism includes a snap-fit ​​part provided on the color temperature film base 410 and a spiral groove provided on the LED base 310. The spiral groove opens obliquely upward, so that the snap-fit ​​part can be screwed into the spiral groove and snapped into the spiral groove.

[0045] In some embodiments of this utility model, a first positioning structure is provided between the LED base 310 and the color temperature film base 410. The first positioning structure can position the first rotating snap-fit ​​mechanism to a snap-fit ​​state. The first positioning structure can position the first rotating snap-fit ​​mechanism, reducing the occurrence of accidental disengagement of the first rotating snap-fit ​​mechanism when there is no external force, and improving the reliability of the mechanism.

[0046] like Figure 4 and Figure 5As shown, in some embodiments of this utility model, the first positioning structure includes a first protrusion 412 disposed on the lower end face of the color temperature filter base 410 and a first sliding groove 313 disposed on the upper end face of the LED base 310. A first limiting part 314 is disposed in the first sliding groove 313. When the color temperature filter base 410 rotates relative to the LED base 310, the first protrusion 412 can slide within the first sliding groove 313 and pass over the first limiting part 314. The first limiting part 314 can restrict the first protrusion 412 from sliding in the opposite direction, thereby restricting the color temperature filter base 410 from rotating in the opposite direction.

[0047] Specifically, the first limiting part 314 breaks the first slide groove 313, so that one end of the first slide groove 313 forms a limiting groove corresponding to the first protrusion 412. After the first protrusion 412 passes the first limiting part 314, it is inserted into the limiting groove, thereby achieving the positioning effect.

[0048] In some embodiments of this utility model, both the LED base 310 and the color temperature plate base 410 are made of plastic material and have a certain elastic recovery performance, so that the first protrusion 412 can pass over the first limiting part 314 and be inserted into the limiting groove.

[0049] It is understood that in some embodiments of this utility model, the first positioning structure may also be provided below the first baffle 312, and a protruding structure may be provided on the lower end surface of the first baffle 312 to form a limiting groove corresponding to the first snap-fit ​​part 411 below the first baffle 312. When the first snap-fit ​​part 411 is screwed into the first snap-fit ​​groove 311, it can be snapped into the limiting groove, thereby realizing the positioning of the first rotary snap-fit ​​mechanism.

[0050] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the lens module 500 includes a lens bracket 510 and a lens body 520 disposed on the lens bracket 510. The lens bracket 510 is detachably installed to the color temperature filter base 410 through a second rotary snap-fit ​​mechanism. The second rotary snap-fit ​​mechanism includes a second snap-fit ​​part 511 and a second screw-fit groove 413 into which the second snap-fit ​​part 511 can be rotatably snapped. One of the second snap-fit ​​part 511 and the second screw-fit groove 413 is disposed on the lens bracket 510, and the other is disposed on the color temperature filter base 410. The detachable installation of the color temperature filter module 400 is realized through the rotary snap-fit ​​cooperation between the second snap-fit ​​part 511 and the second screw-fit groove 413.

[0051] like Figure 4 and Figure 5As shown, in some embodiments of this utility model, the second snap-fit ​​part 511 is provided on the lens bracket 510, and the second screw-fit groove 413 is provided on the color temperature film base 410. The second snap-fit ​​part 511 extends downward and has an L-shaped structure. The second screw-fit groove 413 is an arc-shaped groove, and a second baffle 414 is provided at one end of the second screw-fit groove 413. The second snap-fit ​​part 511 can be inserted into the second screw-fit groove 413 from top to bottom. After the lens bracket 510 is rotated relative to the color temperature film base 410 by a set angle, the second snap-fit ​​part 511 and the second baffle 414 snap-fit ​​together, thereby realizing the detachable installation of the lens module 500.

[0052] Specifically, the side of the second baffle 414 has a notch for the second snap-fit ​​part 511 to be inserted into the second screw-fit groove 413 from top to bottom. The second baffle 414 forms a roughly horizontal second screw-fit groove 413 at its lower part. The lower end of the second snap-fit ​​part 511 is inserted into one end of the second screw-fit groove 413 from top to bottom through the notch. Then, by rotating the lens bracket 510, the second snap-fit ​​part 511 is snapped into the lower part of the second baffle 414, thereby completing the detachable installation of the lens module 500.

[0053] It is conceivable that in some embodiments of this utility model, the second snap-fit ​​part 511 may be an inverted T-shaped structure, the second screw-fit groove 413 may be an arc-shaped groove with an inverted T-shaped cross section, and an opening is provided above one end of the second screw-fit groove 413 for the second snap-fit ​​part 511 to be inserted. After the second snap-fit ​​part 511 is inserted into the second screw-fit groove 413, rotating the lens bracket 510 will allow the second snap-fit ​​part 511 to snap into the second screw-fit groove 413, thereby realizing the detachable installation of the lens module 500.

[0054] It is understood that in some embodiments of this utility model, the second rotating snap-fit ​​mechanism includes a snap-fit ​​part provided on the lens bracket 510 and a spiral groove provided on the color temperature film base 410. The spiral groove opens obliquely upward, so that the snap-fit ​​part can be screwed into the spiral groove and snapped into the spiral groove.

[0055] In some embodiments of this utility model, a second positioning structure is provided between the lens holder 510 and the color temperature film base 410. The second positioning structure can position the second rotary locking mechanism to a locking state. The second positioning structure can position the second rotary locking mechanism, reducing the occurrence of accidental disengagement of the second rotary locking mechanism when no external force is applied, and improving the reliability of the mechanism.

[0056] like Figure 4 and Figure 5As shown, in some embodiments of this utility model, the second positioning structure includes a second protrusion 512 disposed on the lower end face of the lens holder 510 and a second sliding groove 415 disposed on the upper end face of the color temperature film base 410. A second limiting part 416 is disposed in the second sliding groove 415. When the lens holder 510 rotates relative to the color temperature film base 410, the second protrusion 512 can slide in the second sliding groove 415 and pass over the second limiting part 416. The second limiting part 416 can restrict the second protrusion 512 from sliding in the opposite direction, thereby restricting the lens holder 510 from rotating in the opposite direction.

[0057] Specifically, the second limiting part 416 breaks the second slide groove 415, so that one end of the second slide groove 415 forms a limiting groove corresponding to the second protrusion 512. After the second protrusion 512 passes the second limiting part 416, it is inserted into the limiting groove, thereby achieving the positioning effect.

[0058] In some embodiments of this utility model, both the lens holder 510 and the color temperature film base 410 are made of plastic and have a certain elastic recovery performance, so that the second protrusion 512 can pass over the second limiting part 416 and be inserted into the limiting groove.

[0059] It is understood that in some embodiments of this utility model, the second positioning structure may also be provided below the second baffle 414, and a protruding structure is provided on the lower end surface of the second baffle 414 to form a limiting groove corresponding to the second snap-fit ​​part 511 below the second baffle 414. When the second snap-fit ​​part 511 is screwed into the second snap-fit ​​groove 413, it can be snapped into the limiting groove, thereby realizing the positioning of the second rotary snap-fit ​​mechanism.

[0060] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, the lens module 500 includes a lens bracket 510 and a detachable lens body 520 mounted on the lens bracket 510, so that the lens module 500 can replace different lens bodies 520 to meet different usage requirements.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, a limiting ring 110 is detachably installed at the light outlet of the lamp housing 100. The limiting ring 110 can be connected to the lens module 500, so that the light source assembly 200 is limited between the limiting ring 110 and the mounting platform, thereby improving the stability of the installation of the light source assembly 200.
