Description

Technical Field

[0001] This application relates to the field of lighting equipment, and more particularly to an indoor lighting fixture. Background Technology

[0002] In recent years, indoor lighting technology has made significant progress, playing an important role in improving people's quality of life, work efficiency, and creating comfortable living and working environments. With the diversification of architectural design and the increasing demand for personalized lighting, indoor lighting is no longer limited to providing basic brightness, but also needs to meet the lighting requirements of different scenarios and atmospheres.

[0003] In traditional indoor lighting technology, adjusting the brightness of a light bulb is typically achieved by changing the voltage or current of the power supply. For example, a dimmer switch is used to gradually change the resistance in the circuit, thereby adjusting the bulb's wattage. When brightness needs to be reduced, increasing the resistance decreases the current, thus reducing the bulb's brightness; conversely, decreasing the resistance increases the current, making the bulb brighter.

[0004] However, existing indoor lighting brightness adjustment technologies have certain shortcomings. Traditional brightness adjustment methods often only allow for a limited number of adjustment levels, making it difficult to achieve continuous and smooth brightness changes, and thus failing to meet users' brightness needs in different scenarios. Summary of the Invention

[0005] In order to achieve continuous and smooth brightness changes and meet users' brightness needs in different scenarios, this application provides an indoor lighting lamp.

[0006] The indoor lighting fixture provided in this application adopts the following technical solution: An indoor lighting fixture includes a light box, a light source, and a linear drive component; The depth direction of the light box is parallel to the first direction, and along the first direction, one side of the light box is open to form a light outlet; The light source is located inside the light box, and the light-emitting surface of the light source faces the light outlet. The light source is slidably connected to the light box along a first direction, and the linear drive is connected between the light box and the light source to drive the light source to move along the first direction.

[0007] By adopting the above technical solution, the position of the light source in the light box along the first direction is adjusted by the linear drive component, the distance between the light source and the light outlet is changed, and the amount of light emitted is adjusted, so as to realize the continuous and smooth adjustment of the light brightness, which makes up for the defect that the traditional brightness adjustment method can only be adjusted in a limited range.

[0008] Optionally, it also includes a color adjustment component, the color adjustment component comprising: Two first take-up spools are provided, with the first take-up spools parallel to a second direction; in a third direction, the light source is located between the two first take-up spools; the first take-up spools are rotatably connected to the light box about their own axes. Two limiting shafts are connected inside the light box, and the limiting shafts are parallel to the second direction; in the third direction, the light source is located between the two limiting shafts; in the first direction, the limiting shafts are located on the side of the first take-up shaft and the light source near the light outlet; And, flexible transparent colored paper, said flexible transparent colored paper having different color segments; One end of the flexible transparent colored paper is wound onto one of the first winding shafts, and the other end is wound onto the other first winding shaft after passing around the two limiting shafts away from the light source; and the limiting shafts taut the flexible transparent colored paper.

[0009] By adopting the above technical solution and adding a color adjustment component, the rotation of the first winding shaft drives the flexible transparent colored paper with different color segments to move. With the tensioning effect of the limiting shaft, the color of the light emitted from the light outlet can be changed to meet the needs of personalized lighting in different indoor scenes and atmospheres.

[0010] Optionally, the color adjustment component further includes: Two first motors are provided, one for each first take-up shaft and one for each light box, and the first motors are used to drive the first take-up shaft to rotate.

[0011] By adopting the above technical solution, the first motor can drive the first take-up shaft to rotate. The rotation of the first take-up shaft drives the flexible transparent colored paper to move, so that the different color segments of the flexible transparent colored paper pass between the two limiting shafts, thereby changing the color of the light emitted from the light outlet, realizing the adjustment of the color of indoor lighting, and meeting the needs of personalized lighting in different indoor scenes and atmospheres.

[0012] Optionally, it also includes a shape adjustment component, the shape adjustment component comprising: Two second take-up spools are parallel to a second direction and are rotatably connected to the light box about their own axis; in a first direction, the second take-up spools are located on the side of the limiting shaft closer to the light source; in a third direction, two first take-up spools are located between the two second take-up spools. And, a flexible shielding strip, one end of which is wound onto one of the second winding shafts, and the other end is wound onto another second winding shaft after passing around the two limiting shafts away from the light source; the limiting shafts taut the flexible shielding strip, and the flexible transparent colored paper is located between the flexible shielding strip and the limiting shafts; The flexible shielding strip has multiple through holes, each with a different shape, and the holes are spaced apart in the winding direction of the flexible shielding strip.

[0013] By adopting the above technical solution, when the second winding shaft rotates, it will drive the flexible shielding strip to move. Since the flexible shielding strip has multiple perforations of different shapes that are spaced apart in the winding direction, when different perforations move to the path of the light source, the light source passes through the perforations and can illuminate the approximate outline of different shapes and patterns. The edges are blurred and hazy, which can create a soft and dreamy projection effect, thereby realizing the adjustment of the shape of the light and meeting the needs of personalized lighting in different indoor scenes and atmospheres.

[0014] Optionally, the color adjustment component further includes: Two second motors are provided, one for each second take-up shaft and one for each light box. The second motors are used to drive the second take-up shaft to rotate along the light box.

[0015] By adopting the above technical solution, the second motor drives the second take-up shaft to rotate, which in turn moves the flexible shielding strip, so that the perforations of different shapes on the flexible shielding strip pass in front of the light source in sequence, thereby realizing the adjustment of the light shape and meeting the needs of personalized lighting in different indoor scenes and atmospheres.

[0016] Optionally, the limiting shaft is rotatably connected to the light box about its own axis.

[0017] By adopting the above technical solution, the limiting shaft is rotated around its own axis and connected to the light box, which can improve the smoothness of movement of the flexible transparent colored paper and the flexible shielding strip.

[0018] Optionally, a light-shielding frame is also included; the light-shielding frame is fixedly connected to the light box and blocks the outer edge of the light outlet of the light box; In the first direction, the orthographic projection of the inner edge of the light-shielding frame is located inside the outer contour of the front of the flexible shielding strip, and the front of the flexible shielding strip is the portion located between the two limiting axes.

[0019] By adopting the above technical solution, the light-shielding frame can prevent light leakage and ensure the concentration of lighting effect.

[0020] Optionally, a cleanup component may also be included, the cleanup component comprising: A mounting strip parallel to the second direction, the mounting strip being connected to the light-shielding frame, and in the first direction, the mounting strip being located between the front sides of the light-shielding frame and the flexible shielding strip; Additionally, bristles are fixedly connected to the mounting strip, the bristles being in contact with the front of the flexible shielding strip, or in contact with the front of the flexible shielding strip and the flexible transparent colored paper.

[0021] By adopting the above technical solution, the brush bristles can clean the dust on the surfaces of the flexible shielding strip and the flexible transparent paper during their movement, ensuring the light transmittance of the flexible shielding strip and the flexible transparent paper, thereby improving the lighting quality.

[0022] Optionally, the cleaning component further includes: A compression spring, the extension and retraction direction of which is parallel to the first direction, one end of which is fixedly connected to the flexible shielding strip, and the other end of which is fixedly connected to the mounting strip.

[0029] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where X represents the first direction, Y represents the second direction, Z represents the third direction, and the first direction, second direction, and third direction are perpendicular to each other.

[0030] This application discloses an indoor lighting fixture. (Refer to...) Figure 1 and Figure 2 The indoor lighting fixture includes a light box 1, a light source 2, and a linear drive 3; wherein, the light source 2 can move along a first direction within the light box 1 to adjust the brightness; Specifically, the light box 1 has a box structure of a certain depth, with its depth direction parallel to the first direction. Along the first direction, one side of the light box 1 is open, forming a light outlet 11. The light box 1 can be made of metal, such as aluminum alloy, which has good strength and durability, or it can be made of plastic, such as polycarbonate.

[0031] The light source 2 is located inside the light box 1, and the light-emitting surface of the light source 2 faces the light outlet 11. The light source 2 can be an LED light panel, which has high luminous efficiency and low energy consumption, or it can be a fluorescent tube, which emits soft light. The light source 2 is slidably connected to the light box 1 along the first direction. The linear drive 3 is connected between the light box 1 and the light source 2 to drive the light source 2 to move along the first direction. In this embodiment, the linear drive 3 is a linear motor with a driving direction parallel to the first direction. The linear motor is fixedly connected inside the light box 1, and the light source 2 is fixedly connected to the output end of the linear drive 3 to move along the first direction under the drive of the linear drive 3.

[0032] Reference Figure 2 and Figure 3In some embodiments of this application, a color adjustment component 4 is also included, which can change the color of the light. Specifically, the color adjustment component 4 includes two first take-up shafts 41, two limiting shafts 42, and a flexible transparent colored paper 43. The first take-up shafts 41, the limiting shafts 42, and the flexible transparent colored paper 43 are all connected inside the light box 1. The first take-up spool 41 is parallel to the second direction and is rotatably connected to the light box 1 around its own axis. To drive the first take-up spool 41 to rotate, the color adjustment assembly 4 also includes two first motors 44. The first motors 44 are fixedly connected to the outside of the light box 1. Each first take-up spool 41 and the light box 1 are respectively provided with a first motor 44. The first motors 44 are used to drive the first take-up spool 41 to rotate. Specifically, after the first take-up spool 41 passes through the box wall of the light box 1, it is coaxially fixedly connected to the output shaft of the first motor 44 so that the first motor 44 drives the first take-up spool 41 to rotate. The first take-up spool 41 can be mounted on the light box 1 by bearings to ensure the flexibility of rotation. The two first take-up spools 41 are distributed at intervals on the first virtual straight line. The first virtual straight line is parallel to the third direction, and in the third direction, the light source 2 is located between the two first take-up spools 41. Two limiting shafts 42 are also parallel to the second direction and connected inside the light box 1. In the third direction, the light source 2 is located between the two limiting shafts 42. In the first direction, the limiting shafts 42 are located on the side of the first take-up shaft 41 and the light source 2 near the light outlet 11. In some embodiments of this application, the limiting shafts 42 are rotatably connected to the light box 1 around their own axis. A bearing can be provided between the limiting shafts 42 and the light box 1 to improve the smoothness of the connection between the limiting shafts 42 and the light box 1. At the same time, the rotation of the limiting shafts 42 can improve the smoothness of the movement of the flexible transparent colored paper 43. One end of the flexible transparent colored paper 43 is wound onto one of the first winding shafts 41, and the other end is wound onto another first winding shaft 41 after passing around the two limiting shafts 42 away from the light source 2. The limiting shafts 42 tighten the flexible transparent colored paper 43. The flexible transparent colored paper 43 has color segments of different colors, and multiple color segments are distributed sequentially along the winding direction of the flexible transparent colored paper 43. In this way, when the different color segments of the flexible transparent colored paper 43 pass between the two limiting shafts 42, the color of the light emitted from the light outlet 11 can be changed.

[0033] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of this application, a shape adjustment component 5 is also included, which can adjust the shape of the light; specifically, the shape adjustment component 5 includes two second take-up rollers 51 and a flexible shielding strip 52; The second take-up shaft 51 is parallel to the second direction and is rotatably connected to the light box 1 around its own axis. In order to drive the second take-up shaft 51 to rotate, the color adjustment component 4 also includes two second motors 53. Each second take-up shaft 51 and the light box 1 are respectively provided with a second motor 53. The housing of the second motor 53 is fixedly connected to the light box 1. After the second take-up shaft 51 passes through the box wall of the light box 1, it is coaxially fixedly connected to the output shaft of the second motor 53 so that the second motor 53 drives the second take-up shaft 51 to rotate along the light box 1. In the first direction, the second take-up spool 51 is located on the side of the limiting shaft 42 closer to the light source 2; the two second take-up spools 51 are spaced apart on the second virtual straight line, the second virtual straight line is parallel to the third direction, and in the third direction, the two first take-up spools 41 are located between the two second take-up spools 51. The flexible shielding strip 52 can be made of rubber, which has good flexibility and light-blocking properties. One end of the flexible shielding strip 52 is wound around one of the second winding shafts 51, and the other end is wound around the side away from the light source 2 after passing around the two limiting shafts 42. The limiting shafts 42 tighten the flexible shielding strip 52, and the flexible transparent colored paper 43 is located between the flexible shielding strip 52 and the limiting shafts 42. Multiple perforations 521 are opened through the flexible shielding strip 52. The multiple perforations 521 have different shapes and are spaced apart in the winding direction of the flexible shielding strip 52. The front side of the flexible shielding strip 52 is the part located between the two limiting shafts 42. When different perforations 521 are located on the front side of the flexible shielding strip 52, the light source passes through the perforations 521, which can illuminate the general outline of the pattern. Its edges are blurred and hazy, creating a soft and dreamy projection effect. If a clear edge is required, a light-concentrating element, such as a light-concentrating lens, can be fixed between the flexible shielding strip 52 and the light source, and an imaging element, such as an imaging lens, can be fixed on the side of the flexible shielding strip 52 away from the light source. This is a conventional setting in the field, and this application will not elaborate on it here.

[0034] Reference Figure 5 In some embodiments of this application, a light-shielding frame 6 is also included, which can prevent light from leaking out. The light-shielding frame 6 is fixedly connected to the light box 1 and blocks the outer edge of the light outlet 11 of the light box 1. In the first direction, the orthographic projection of the inner edge of the light-shielding frame 6 is located inside the front outer contour of the flexible shielding strip 52. The light-shielding frame 6 can be made of black material to effectively absorb light and prevent light from leaking out.

[0035] Reference Figure 5In some embodiments of this application, a cleaning component 7 is also included. The cleaning component 7 can clean the flexible shielding strip 52 and the flexible transparent colored paper 43. The cleaning component 7 includes an mounting strip 71 parallel to the second direction and bristles 72 fixedly connected to the mounting strip 71. The mounting strip 71 is connected to the light-shielding frame 6. In the first direction, the mounting strip 71 is located between the front surfaces of the light-shielding frame 6 and the flexible shielding strip 52. The bristles 72 are in contact with the front surface of the flexible shielding strip 52, or with the front surface of the flexible shielding strip 52 and the flexible transparent colored paper 43. When the bristles 72 are in contact with the flexible shielding strip 52 and the flexible transparent colored paper, they can clean the dust on the surfaces of both. In some embodiments of this application, the cleaning component 7 further includes a compression spring 73 and a telescopic rod 74. The extension and retraction directions of the compression spring 73 and the telescopic rod 74 are both parallel to the first direction. One end of the compression spring 73 is fixedly connected to the flexible shielding strip 52, and the other end is fixedly connected to the mounting strip 71. One end of the telescopic rod 74 is fixedly connected to the flexible shielding strip 52, and the other end is fixedly connected to the mounting strip 71.

There are two cleaning components 7, which are distributed at intervals in the third direction, and the inner side of the light-shielding frame 6 is located between the two cleaning components 7.

[0036] The implementation principle of an indoor lighting lamp according to an embodiment of this application is as follows: The indoor lighting lamp adjusts the position of the light source 2 within the light box 1 through a linear drive component 3, achieving continuous and smooth adjustment of the light brightness, thus overcoming the limitation of traditional brightness adjustment methods that can only adjust to a limited number of levels. The color adjustment component 4 drives the first take-up shaft 41 to rotate via a first motor 44, causing flexible transparent colored paper 43 of different color segments to move, thereby changing the light color. The shape adjustment component 5 drives the second take-up shaft 51 to rotate via a second motor 53, causing flexible shielding strips 52 with different shaped perforations 521 to move, adjusting the shape of the light. The light-shielding frame 6 prevents light leakage and ensures the concentration of the lighting effect. The cleaning component 7 uses bristles 72 and compression springs 73 to clean the flexible shielding strips 52 and flexible transparent colored paper 43 as they move, ensuring light transmittance, improving lighting quality, and meeting the needs for personalized lighting in different indoor scenes and atmospheres. Compared with existing traditional indoor lighting technologies, this represents a significant improvement and enhancement.
