[0002] Lamps are a type of lighting equipment and an essential part of our daily lives.

[0003] In home lighting, the color temperature of light directly affects the user experience. Light sources usually only emit white light, but white light is a mixture of light of different wavelengths (red, green, blue, etc.). At this time, the filters set in the light fixture can absorb or subtract specific wavelengths of light, so that the remaining light that passes through will present different color temperatures. Using appropriate color temperature light fixtures in different environments can improve the user's comfort.

[0004] Existing LED lighting fixtures have a single light source, and each fixture can usually only emit a beam of light with one color temperature, which often makes it difficult to adapt to different needs.

[0005] Therefore, this utility model provides a lamp filter switching device with adjustable color temperature. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 As shown in the embodiment of this utility model, an adjustable color temperature lamp filter switching device includes a lamp housing 1; multiple lamp source modules 2 are installed inside the lamp housing 1; multiple lamp covers 3 are fixedly connected to the top of the lamp housing 1; the lamp covers 3 are positioned above the lamp source modules 2; a switching groove 4 is provided inside the lamp housing 1; an adjustment knob 6 is rotatably connected to the top of the lamp housing 1; multiple connecting rods 7 are fixedly connected to the middle of the adjustment knob 6; an adjustment disk 8 is fixedly connected to the end of the connecting rods 7; the adjustment disk 8 is located inside the switching groove 4; multiple filters 9 are fixedly connected to the middle of the adjustment disk 8; the filters 9 are located between the lamp source modules 2 and the lamp covers 3, and during operation, the filters 9 located on the adjustment disk 8 adjust according to the color temperature difference. The staggered arrangement allows the light source module 2 to emit white light when powered on. This white light passes through the upper filter 9, and after filtering, the light is converted into either a cool or warm color tone before being emitted through the lampshade 3. When the color temperature needs to be adjusted to another setting, the user rotates the adjustment knob 6, which in turn rotates the adjustment disc 8 located inside the switching slot 4. This changes the position of the adjacent filter 9. Under the filtering effect of the filter 9, the light emitted from the light source module 2 changes from a cool color temperature to a warm color temperature or vice versa when it reaches the lampshade 3. The color temperature can be adjusted by switching the position of the filter 9, allowing users to adjust the color temperature according to their own needs, making it more convenient and practical.

[0024] like Figure 3 As shown, a drive motor 5 is fixedly connected to the bottom of the inner wall of the lamp housing 1; multiple fan blades 10 are fixedly connected to the middle of the output end of the drive motor 5; multiple upper through holes 11 are opened on the top of the lamp housing 1; multiple lower through holes 12 are opened on the bottom of the lamp housing 1. During operation, the drive motor 5 is connected to the power supply of the lamp itself. When the lamp itself is powered on, the drive motor 5 is also powered on. During the use of the lamp source module 2, a large amount of heat is generated inside the lamp housing 1. At this time, the drive motor 5, which has been powered on, will drive the fan blades 10 at the output end to rotate, thereby causing air to circulate inside the lamp housing 1 through the upper through holes 11 and the lower through holes 12, carrying the heat inside the lamp housing 1 to the outside, achieving the heat dissipation effect of the lamp source module 2, and reducing the problem of high temperature damage caused by long-term operation of the lamp.

[0025] like Figure 4As shown, multiple sealing gaskets 13 are fixed to the top and bottom of the adjustment disk 8. The sealing gaskets 13 are sleeved on the filter 9. During operation, by setting multiple sealing gaskets 13 between the adjustment disk 8 and the switching groove 4 and sleeved on the filter 9, the problem of light scattering outward from the lamp source module 2 can be reduced, and the light can be more concentrated and emitted outward through the lamp cover 3, thereby improving the lighting effect.

[0026] like Figure 3 and Figure 4 As shown, a plurality of ball bearings 14 are installed at the bottom of the adjusting disk 8; the ball bearings 14 are in contact with the inner sidewall of the switching groove 4. During operation, the ball bearings 14 are arranged between the adjusting disk 8 and the switching groove 4, which enables the ball bearings 14 to support the adjusting disk 8, making the adjusting disk 8 more stable during placement and movement, while reducing frictional loss between the adjusting disk 8 and the switching groove 4 when rotating, thus improving the stability and durability of the adjusting disk 8 during operation.

[0027] The bottom of the lamp source module 2 is fixed with a heat sink. When working, the heat sink is added to guide the heat generated by the lamp source module 2, so that the heat can be better dissipated to the outside, thereby improving the heat dissipation effect of the lamp source module 2 and increasing the stability of the lamp source module 2 during operation.

[0028] like Figure 3 and Figure 4 As shown, an anti-slip pad 15 is fixedly attached to the top of the inner wall of the lamp housing 1; the anti-slip pad 15 is sleeved on the adjustment knob 6 and is rotatably connected to the adjustment knob 6. During operation, by setting the anti-slip pad 15 on the adjustment knob 6, the frictional resistance of the adjustment knob 6 when it does not need to be rotated can be increased, reducing the problem of the adjustment knob 6 slipping and causing the filter 9 to switch, and improving the stability of the adjustment knob 6 during operation.

[0029] Working principle: The filters 9 on the adjustment dial 8 are alternately set according to the difference between cool and warm colors. When the light source module 2 is powered on, it emits white light. The white light passes through the filters 9 above, and after filtering, the light is transformed into either a cool or warm color tone and emitted outward through the lampshade 3. When it is necessary to adjust the color temperature to another form, the user rotates the adjustment knob 6, which in turn rotates the adjustment dial 8 located inside the switching slot 4. At this time, the position of the adjacent filters 9 changes. Under the filtering effect of the filters 9, the light emitted by the light source module 2 changes from a cool color temperature to a warm color temperature or vice versa when it reaches the lampshade 3. The color temperature is adjusted by switching the position of the filters 9, allowing users to adjust the color temperature according to their own needs, which is more convenient and practical.

[0030] The drive motor 5 is connected to the power supply of the lamp itself. When the lamp itself is powered on, the drive motor 5 is also powered on. During the use of the lamp source module 2, a lot of heat is generated inside the lamp housing 1. At this time, the drive motor 5, which has been powered on, will drive the fan blade 10 at the output end to rotate, thereby causing the air to circulate inside the lamp housing 1 through the upper through hole 11 and the lower through hole 12, carrying the heat inside the lamp housing 1 to the outside, achieving the heat dissipation effect of the lamp source module 2, and reducing the problem of high temperature damage caused by the lamp working for a long time.

[0031] By setting multiple sealing gaskets 13 between the adjustment plate 8 and the switching slot 4 and covering them on the filter 9, the problem of light scattering outward from the lamp source module 2 can be reduced, allowing the light to be emitted outward through the lamp cover 3 in a more concentrated manner, thereby improving the lighting effect.

[0032] The ball bearing 14 is installed between the adjusting plate 8 and the switching groove 4, which enables the ball bearing 14 to support the adjusting plate 8, making the adjusting plate 8 more stable during placement and movement. At the same time, it reduces the frictional loss between the adjusting plate 8 and the switching groove 4 when the adjusting plate 8 rotates, and improves the stability and durability of the adjusting plate 8 during operation.

[0033] By adding a heat sink, the heat generated by the lamp source module 2 during operation is guided outward, which improves the heat dissipation effect of the lamp source module 2 and increases the stability of the lamp source module 2 during operation.

[0034] By setting an anti-slip pad 15 on the adjustment knob 6, the frictional resistance of the adjustment knob 6 when it is not needed to rotate can be increased, reducing the problem of the adjustment knob 6 slipping and causing the filter 9 to switch, and improving the stability of the adjustment knob 6 when it is working.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
