Description

Technical Field

[0001] The utility model relates to the technical field of lighting tools, in particular to a lighting decoration which is convenient for adjusting the light color. Background Art

[0002] Lighting - the eyes of the home. If there are no lamps in the home, it is like a person without eyes. A family without eyes can only live in darkness, so the position of the lamp in the home is crucial. Nowadays, people call all lighting lamps lighting. From the name, we can see that lamps are not only used for lighting, but also can be used to decorate the room. The current types of LED series lighting lamps are diverse, from living rooms, dining rooms, bedrooms, kitchens and bathrooms to walkways, balconies, and bars, from indoors to outdoors, more to embellish the surrounding environment. The design styles of modern lighting lamps are becoming more and more diverse, classical, modern, fashionable, European, American, refreshing, luxurious, and beautiful. This requires indoor lighting companies to have sufficient foresight and innovation awareness, and design products that satisfy consumers according to the changing needs of consumers. Lighting not only plays a role in home lighting, but different styles can embellish different effects. At present, the beam angles of most lighting lamps are fixed and cannot be adjusted. Sometimes, if different lighting effects are required in different environmental atmospheres, multiple sets of lighting lamps need to be installed, which is inconvenient.

[0003] This case was created to solve the above problems. Utility Model Content

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a lighting fixture that is easy to adjust the light color, including a base plate, a supporting column, a lamp tube, and an outer baffle, wherein a rotating outward expansion structure is provided inside the outer baffle, and the rotating outward expansion structure includes a first gear, a connecting column, a limiting column, and a second gear, and the center of the first gear is hollow.

[0008] Preferably, the outer baffles are multiple pieces, and the inner side walls of the multiple outer baffles are respectively fixedly connected to a connecting column, and a fixing column is provided on the connecting column near the outer baffle.

[0009] Preferably, limiting columns are provided at the upper and lower ends of the connecting column near the first gear, and a groove is circumferentially provided on the first gear.

[0010] Preferably, each of the circumferentially arranged grooves corresponds to a connecting column, and each limiting column is located in the corresponding groove.

[0011] Preferably, a fixed slide rail is provided on the end of each of the connecting columns, and the end of each fixed slide rail is fixedly connected to the center of the first gear.

[0012] Preferably, a second gear is disposed inside the outer baffle, and the second gear meshes with the first gear.

[0013] (III) Beneficial effects

[0014] After adopting the above technical scheme, the utility model has the following advantages compared with the prior art: the utility model is a lighting fixture that is easy to adjust the color of the light. By rotating the outward expansion structure, the second gear drives the first gear to rotate and then drives the limit column to move in the groove, so that the connecting column is extended and the outer baffle is expanded outward, thereby changing the beam angle of the light, achieving different lighting effects that are more focused, brighter and more dispersed, and improving the versatility of the device.

[0019] The utility model is further described in detail below through the drawings and embodiments.

[0020] like Figure 1-3 As shown: A lighting fixture that is easy to adjust the color of light, including a base plate 1, a supporting column 2, a lamp tube 3, and an outer baffle 4. A rotating outward expansion structure is provided in the outer baffle 4, and the rotating outward expansion structure includes a first gear 8, a connecting column 5, a limiting column 7, and a second gear 10. The first gear 8 is hollow at the center, and the hollow part is connected to fix the lamp tube 3 through an electric wire. The second gear 10 is rotatably connected to the base plate of the outer baffle 4 and is driven by an overall power supply to rotate counterclockwise, thereby driving the first gear 8 to rotate counterclockwise. At this time, the limiting column 7 located in the groove is displaced from bottom to top along the groove 7. At this time, the connecting column 5 moves upward to complete the outward expansion of the outer baffle 4, thereby realizing the adjustment of the beam angle.

[0021] There are multiple outer baffles 4, and the inner side walls of the multiple outer baffles 4 are respectively fixedly connected with a connecting column 5. A fixing column 6 is provided on the connecting column 5 near the outer baffle 4, and the outer baffle 4 is driven to expand outward or contract inward through the displacement of the connecting column 5.

[0022] Limiting columns 7 are provided at the upper and lower ends of the connecting column 5 near the first gear 8. A groove 9 is circumferentially provided on the first gear 8. Each circumferentially arranged groove 9 corresponds to a connecting column 5. Each limiting column 7 is located in the corresponding groove 9. The straight-line distance between the upper and lower ends of the groove 9 is the displacement distance of the connecting column 5.

[0023] A fixed slide rail is provided on the end of each connecting column 5, and each fixed slide rail end is fixedly connected to the center of the first gear 8. When the limiting column 7 drives the connecting column 5 to move, the moving column 5 slides on the slide rail, and the slide rail plays a role of firmly supporting the moving column 5.

[0024] A second gear 10 is provided inside the outer baffle 4, and the second gear 10 is meshed with the first gear 8. The lamp tube 3 adopts a control method that only requires two power lines and no signal lines. The effect of changing the color of the light is achieved through a PWM duty cycle. The second gear 10 and the circuit connection through the hollow center of the first gear 8 are both existing lamp tube connection methods.

[0025] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
