Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically relating to a swing-type lamp that can adjust the dynamic distribution of light in space. Background Technology

[0002] Currently, static LED ceiling lights or track lights have become the mainstream solution for living room lighting. Their light emission angle, luminous flux, and spectral distribution are locked instantly upon power-on, ensuring that the ocular surface remains in a constant environment of "constant light intensity—constant color temperature—constant angle of incidence" for users during 2–6 hours of movie watching, reading, or parent-child interaction. Extensive evidence-based medical data shows that when the rate of change in the light dose received per unit area of ​​the cornea (irradiance × time) is less than 10% within 30 minutes, the corneal epithelial cells' sodium... + / K + - ATPase activity decreased significantly, tear film lipid layer thickness decreased, and blink frequency decreased from the normal 12 times / min. -1 Passive reduction to 7 times / min -1 This can lead to "video terminal syndrome (CVS)" and early dry eye syndrome.

[0003] Although introducing a desktop auxiliary light or a dynamic dimming system can break the static balance of light distribution to some extent, these solutions all rely on active user operation and cannot form a continuous, periodic beam scan in the spatial dimension. Therefore, they fail to fundamentally solve the problem of corneal "light adaptation inertia". Summary of the Invention

[0004] To address the problem that prolonged exposure to constant light intensity can lead to a significant decrease in the enzyme activity of corneal epithelial cells, this invention provides a swing-type lamp that can adjust the dynamic distribution of light in space.

[0005] The objective of this invention can be achieved through the following technical solutions: A swing-type lamp that can adjust the dynamic distribution of light in space includes a fixed frame, a transmission device, and a lamp assembly. The fixed frame is suspended from the ceiling of the room. The transmission device is mounted on the fixed frame and its output end is connected to the lamp assembly to control the lamp assembly to swing.

[0006] As a preferred embodiment of the present invention, the transmission device includes a transmission assembly, which includes a drive gear, a first gear, a first connecting rod, and a first swing member. The drive gear and the first gear are rotatably mounted on the fixed frame and are meshed together. The bottom of one end of the first swing member is hinged to the fixed frame. The two ends of the first connecting rod are respectively hinged to the circumferential surface of the first gear and the top of one end of the first swing member. When the drive gear rotates, the first swing member can swing back and forth at a certain angle. The lighting assembly includes a first long strip light, which is connected to the other end of the first swing member.

[0007] As a preferred embodiment of the present invention, the transmission assembly further includes a second gear, a second connecting rod, and a second swing member. The second gear is rotatably mounted on the fixed frame and meshes with the first gear. The bottom of one end of the second swing member is hinged to the fixed frame. The two ends of the second connecting rod are respectively hinged to the circumferential surface of the second gear and the top of one end of the second swing member. When the driving gear rotates, the second swing member can swing back and forth at a certain angle. The lighting assembly further includes a second long strip light, which is connected to the other end of the second swing member.

[0008] As a preferred embodiment of the present invention, the first swing member and the second swing member are symmetrically arranged on both sides of the fixed frame.

[0009] As a preferred embodiment of the present invention, the transmission device further includes a drive motor and a drive shaft. The drive motor is mounted on the fixed frame, and the drive shaft is rotatably mounted on the fixed frame. The output end of the drive motor is coaxially connected to the drive shaft, and the drive shaft is coaxially connected to the drive gear. The cross-sectional shape of the drive shaft is a non-circular structure, and the drive gear is coaxially provided with a mating hole that matches the cross-sectional shape of the drive shaft.

[0010] As a preferred embodiment of the present invention, a plurality of transmission components are provided, and the plurality of transmission components are equally spaced along the axial direction of the fixed frame; a plurality of lighting components are provided, and the plurality of lighting components are matched with the plurality of transmission components, and any one of the lighting components is connected to the corresponding transmission component.

[0011] As a preferred embodiment of the present invention, the hinge point between the first connecting rod and the first gear is defined as the first hinge point. Along the axial direction of the fixed frame, several first hinge points are different from each other and rotate clockwise sequentially along the central axis of the drive shaft.

[0012] As a preferred embodiment of the present invention, the lighting component emits a constant light intensity.

[0013] As a preferred embodiment of the present invention, the first long strip light includes a hollow lamp shell, a light strip, and a lamp cover.

The lamp cover is fastened to the lamp shell.

[0014] As a preferred embodiment of the present invention, the lamp cover is an LED lamp diffusion film.

[0015] The beneficial effects of this invention are as follows: The lighting component is connected to the output of a transmission device to control its oscillation. It should be noted that the lighting component emits a constant light intensity. Due to the oscillation of the lighting component, the light intensity in the area changes constantly. This change can be detected by the cornea of ​​the human eye but not by the retina. Therefore, the change in light intensity is not perceptible to the human eye, but it can significantly increase the enzyme activity of corneal epithelial cells. This solves the problem that users are exposed to constant light intensity for a long time, which leads to a significant decrease in the enzyme activity of corneal epithelial cells.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] Please see Figures 1-3 This embodiment provides a swing-type lamp that can adjust the dynamic distribution of light in space, including a fixed frame 1, a transmission device, and a lamp assembly. The fixed frame 1 is suspended from the ceiling of the room. The transmission device is mounted on the fixed frame 1, and its output end is connected to the lamp assembly to control the swing of the lamp assembly. It should be noted that the lamp assembly releases a constant light intensity. Due to the swing of the lamp assembly, the light intensity in the area changes constantly. This change can be captured by the cornea of ​​the human eye but not by the retina. Therefore, the change in light intensity is not perceptible to the human eye, but it can significantly increase the enzyme activity of corneal epithelial cells, solving the problem of a significant decrease in the enzyme activity of corneal epithelial cells caused by prolonged exposure to a constant light intensity environment.

[0021] Specifically, the transmission device of this solution includes a transmission assembly 2, which includes a drive gear 201, a first gear 202, a first connecting rod 203, and a first swing member 204. The drive gear 201 and the first gear 202 are rotatably mounted on the fixed frame 1 and are meshed together. The bottom of one end of the first swing member 204 is hinged to the fixed frame 1. The two ends of the first connecting rod 203 are respectively hinged to the circumferential surface of the first gear 202 and the top of one end of the first swing member 204. When the drive gear 201... When 01 rotates, the first swing member 204 can swing back and forth at a certain angle; the lighting assembly includes a first long strip light 3, which is connected to the other end of the first swing member 204; with this arrangement, when the drive gear 201 rotates, it will drive the first gear 202 to rotate, and finally, under the restriction of the first connecting rod 203, the first swing member 204 swings back and forth at a certain angle. From the axial direction of the fixed frame 1, the first long strip light swings back and forth at a certain angle on one side of the fixed frame 1.

[0022] Furthermore, the transmission assembly 2 also includes a second gear 205, a second connecting rod 206, and a second swing member 207. The second gear 205 is rotatably mounted on the fixed frame 1 and meshes with the first gear 202. The bottom of one end of the second swing member 207 is hinged to the fixed frame 1. The two ends of the second connecting rod 206 are respectively hinged to the circumferential surface of the second gear 205 and the top of one end of the second swing member 207. When the drive gear 201 rotates, the second swing member 207 can swing back and forth at a certain angle. The lighting assembly also includes a second long strip light 4, which is connected to the other end of the second swing member 207. Similarly, with this arrangement, when the drive gear 201 rotates, it will drive the second gear 205 to rotate. Finally, under the restriction of the second connecting rod 206, the second swing member 207 swings back and forth at a certain angle. Viewed from the axial direction of the fixed frame 1, the second long strip light swings back and forth at a certain angle on the other side of the fixed frame 1. Furthermore, it should be noted that in order to ensure that the light intensity on both sides of the fixed frame 1 always changes synchronously, the first swing member 204 and the second swing member 207 are symmetrically arranged on both sides of the fixed frame 1, and the first gear 202 and the second gear 205 are symmetrically arranged on both sides of the fixed frame 1, and the first connecting rod 203 and the second connecting rod 206 are symmetrically arranged on both sides of the fixed frame 1. This arrangement ensures that the first and second strip lights can move symmetrically along the axial direction of the fixed frame 1, thereby ensuring that the light intensity on both sides of the fixed frame 1 always changes synchronously.

[0023] Specifically, to achieve the rotation of the drive gear 201, the transmission device of this solution also includes a drive motor 208 and a drive shaft 209. The drive motor 208 is mounted on the fixed frame 1, and the drive shaft 209 is rotatably mounted on the fixed frame 1. The output end of the drive motor 208 is coaxially connected to the drive shaft 209, and the drive shaft 209 is coaxially connected to the drive gear 201. The cross-sectional shape of the drive shaft 209 is a non-circular structure, and the drive gear 201 is coaxially provided with a mating hole that matches the cross-sectional shape of the drive shaft 209. With this arrangement, when the drive motor 208 starts working, it will drive the drive shaft 209 to rotate. Since the drive gear 201 is coaxially sleeved on the drive shaft 209, and the cross-sectional shape of the drive shaft 209 is a non-circular structure, this ensures that when the drive shaft 209 rotates, the drive gear 201 will rotate along with it.

[0024] Furthermore, since the illumination range of a single lighting component is limited, in order to ensure that it can meet the needs of spacious rooms, this solution provides several transmission components 2, which are equally spaced along the axis of the fixed frame 1; several lighting components are provided, which are matched with several transmission components 2, and any lighting component is connected to the corresponding transmission component 2; by setting several sets of lighting components, the product of this solution can meet the needs of rooms of different sizes.

[0025] Furthermore, it should be noted that the hinge point between the first connecting rod 203 and the first gear 202 is defined as the first hinge point. Along the axial direction of the fixed frame 1, several first hinge points are different from each other and rotate clockwise sequentially along the central axis of the drive shaft 209. Through this design, a spatial phase difference is introduced on the basis of the original reciprocating oscillation, so that the entire lamp no longer performs simple synchronous oscillation, but forms a wave-like progressive scanning. This design first upgrades the beam trajectory from "single-point return" to "traveling wave propulsion": at the same time, each lamp body is at a different swing angle, and the light band moves continuously along the depth of the room. The change in illuminance received by the cornea of ​​the user in the room is transformed from "intermittent impact" to "continuous micro-perturbation". It can increase the number of effective stimulations by n times without increasing the driving frequency, which satisfies the low frequency and high gradient conditions required for tear film metabolism, and avoids the noise and wear caused by high-frequency gear meshing. Secondly, the spatial phase difference disperses the maximum light output angle across different moments, reducing the peak wall illuminance by about half and lowering the Unified Glare Index (UGR) peak by 1.5–2.0 units, significantly reducing instantaneous glare. Simultaneously, the light spot maintains a moderate speed throughout the traveling wave, eliminating the localized overbrightness caused by the "zero-speed dwell" at extreme angles in traditional reciprocating oscillations. This improves illuminance uniformity from 0.4 to over 0.6, eliminating the need for frequent pupil adjustment and enhancing visual comfort. Thirdly, the traveling wave scanning distributes brightness variations within the same cycle over a wider spatiotemporal region. The corneal sampling frequency increases exponentially while the drive frequency remains low, allowing the motor to maintain ultra-quiet operation at 0.2–0.8 Hz, ensuring the luminaire's lifespan and reliability.

[0026] Specifically, the first long strip light 3 of this solution includes a hollow lamp shell, a light strip, and a lamp cover. One end of the lamp shell is connected to the other end of the first swing member 204. The light strip is set inside the lamp shell and is composed of several LED beads connected in series. The lamp cover is fastened to the lamp shell. Similarly, the structure of the second long strip light 4 is the same as that of the first long strip light 3. It should be noted that since the light strip is composed of several LED beads connected in series, the light intensity emitted by the first long strip light 3 cannot be uniform everywhere. Based on this, in order to solve this problem, the lamp cover of this solution is an LED light diffusion film. By setting the LED light diffusion film, the directional beam emitted by the point light source LED is repeatedly refracted and reflected at multiple interfaces using the Mie scattering principle, and finally converted into cosine distributed Lambertian light output. The brightness uniformity can be improved from 0.3 when bare lamp to more than 0.85, eliminating bright spots and dark lines generated by chip array. While ensuring uniform light intensity distribution, it forms a soft and glare-free dynamic lighting environment for the cornea.
