Description

Technical Field

[0001] This utility model relates to the field of decorative lighting technology, specifically a lighting fixture that simulates a skylight effect. Background Technology

[0002] With the development of lighting technology and the improvement of people's living standards, people's requirements for lighting have moved beyond simple illumination to include healthy lighting, emphasizing both visual and non-visual effects, improving the light environment, and thus meeting physiological and psychological needs for healthy lighting. High-rise buildings and densely packed buildings often result in insufficient indoor lighting, especially during rainy seasons or in north-facing rooms. Long-term reliance on artificial lighting can easily lead to visual fatigue and low mood. Humans have an instinctive yearning for the sky and sunlight; enclosed spaces can easily create a sense of oppression, while natural light and dynamic light and shadow can bring psychological comfort. Ordinary lamps only provide basic lighting and cannot simulate the color and intensity variations of natural light, nor do they offer dynamic scenes. Cool white light or a single warm light is insufficient to create a warm and healing atmosphere, failing to meet emotional needs. Therefore, this paper proposes a lamp that simulates the effect of a skylight. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figure 1 As shown, this utility model provides a technical solution: a lamp that simulates a skylight effect, including a lamp frame 1, a light source structure 2 with an aspherical lens structure is fixedly installed inside the lamp frame 1, a grid layer 3 is provided below the light source structure 2, the grid layer 3 is a black mesh structure grid layer, a diffusion layer 4 is attached below the grid layer 3, and a sky layer 5 is provided below the diffusion layer 4.

[0020] The lamp frame 1 is equipped with a partition bracket 6, which is located between the light source structure 2 and the grid layer 3. The lamp frame 1 is also equipped with a partition bracket 7, which is located between the diffusion layer 4 and the sky layer 5. A face cover 101 is fixedly connected to one side of the lamp frame 1, and the sky layer 5 is located between the partition bracket 7 and the face cover 101.

[0021] In one embodiment, the light source structure 2 includes an LED light source 201, a lens bracket 202, and a lens 203. The lens bracket 202 is fixedly connected to one side of the LED light source 201, and the aspherical lens 203 is fixedly connected to one side of the lens bracket 202.

[0022] Example 2: Please refer to 2. Based on Example 1, the sky layer 5 is replaced with a light guide structure, and LED beads 8 capable of producing multiple colors are set on both sides of the sky layer 5. In this example, the sky layer 5 adopts a light guide structure. By changing the color of the LED beads, the effect of different colored skies can be easily achieved, such as sunrise, sunset, blue sky, etc.

[0023] Example 3: Please refer to the following carefully. Figure 3 A lighting fixture simulating a skylight effect includes a light frame 1, a light source structure 2 fixedly installed inside the light frame 1, a grid layer 3 below the light source structure 2, the grid layer 3 being a black mesh structure, a diffusion layer 4 attached below the grid layer 3, and a sky layer 5 below the diffusion layer 4.

[0024] The lamp frame 1 is equipped with a partition bracket 6, which is located between the light source structure 2 and the grid layer 3. The lamp frame 1 is also equipped with a partition bracket 7, which is located between the diffusion layer 4 and the sky layer 5. A face cover 101 is fixedly connected to one side of the lamp frame 1. The sky layer 5 is located between the partition bracket 7 and the face cover 101. In this embodiment, the light source structure 2 is a light source with a built-in lens structure, so that the sky layer 5 adopts a light guide structure, and LED beads 8 capable of producing multiple colors are arranged on both sides of the sky layer 5.

[0025] In this embodiment, the light source has an integrated lens structure, allowing for different light angles to be achieved by replacing the LEDs. Combining the light source and the grid layer can also create a virtual sun effect. The optical structure is simple, easy to install, and cost-effective. Alternatively, the sky layer in this embodiment can also achieve the sky effect using the structure in Embodiment 1. In the figure, the lens in this embodiment is a convex structure. Another preferred option is a light source package with a built-in lens, which does not require a convex structure; the lens structure is integrated inside the light source bracket to protect the lens from damage.

[0026] Working principle: 1. The working principle of generating a virtual sun; 1. Multi-unit structural characteristics of aspherical lenses: Aspherical lenses consist of numerous small lens units, each independently focusing light rays. As the eye moves, these lens units at different angles reflect / refract light rays into the pupil, creating a dynamic optical feedback effect. This lens system employs a multi-row array design, with the focal point of the first row of lenses coinciding with the center of the second row. When the viewing angle changes, the relative displacement of the optical axes of the two rows of lenses causes a change in the direction of the outgoing light rays, resulting in a noticeable dynamic light effect.

[0027] 2. Refractive accommodation of the human eye's lens: The human eye adjusts its focal length by changing the thickness of the lens. When observing lens units at different angles, the path of light refraction shifts with the change in viewing angle. This dynamic adjustment interacts with the array structure of the lenses, enhancing the visual effect of light movement.

[0028] 3. Derivation of physical formulas: Parallax angle calculation: Let the baseline distance (interpupillary distance) be BB, the object depth be ZZ, and the parallax angle θ satisfy: θ≈BZ (when...) )θ≈ZB(when This formula shows that parallax is inversely proportional to depth. Lens displacement response: For a single-lens unit with a focal length ff, the image point displacement Δx caused by the change in viewing angle Δα is: The total displacement after the superposition of multiple units is discretized.

[0029] Relationship between depth and parallax: The relationship between depth ZZ and disparity dd in a binocular system is as follows: Where ff is the equivalent focal length and BB is the baseline distance.

[0030] Analysis from the perspective of the human eye: Dynamic sensing mechanism; The human eye's lens accommodation (approximately 20-30Hz) interacts with the lens's high-frequency response, causing the light path to change in a "jumping" manner when the viewer moves.

[0031] Stereoscopic vision enhancement; The depth information generated by binocular parallax (approximately 65mm baseline) is superimposed on the microscopic displacement effect of the lens, creating a stronger sense of stereoscopic depth. When the rate of change of viewing angle exceeds the human eye's fusion threshold (approximately 15° / s), a noticeable linkage effect occurs.

[0032] Second: The working principle of generating blue skies; 1. The Rayleigh plate simulates the principle of Rayleigh scattering. When specific light passes through the Rayleigh plate, it produces the effect of a blue sky.

[0033] Rayleigh scattering is an important optical phenomenon referring to the elastic scattering process that occurs when light passes through a transparent medium (such as the Earth's atmosphere) under conditions where the incident light wavelength is much larger than the diameter of the medium's molecules (typically less than 1 / 10 of the wavelength of visible light). Research has found that this scattering has two significant characteristics: first, the intensity of the scattered light is inversely proportional to the fourth power of the incident light wavelength (i.e., ...). This law was named "Rayleigh scattering law"; secondly, the scattered light retains the frequency of the incident light and does not undergo energy change. This theory perfectly explains why clear skies appear blue (short-wavelength blue light is scattered more strongly) and why the sun appears red at sunset, becoming a foundational achievement in atmospheric optics research.

[0034] 2. The light source and the angle of incident light in the present invention both conform to the above principle, which can produce the effect of a blue sky.

[0035] Three: The principle of generating projected light spots; 1. This design uses small-angle lenses (approximately 1-3°) arranged in an array, which can significantly increase the central light intensity. The area contrasts sharply with its surroundings, creating a projected spot of sunlight as it shines through the skylight.

[0036] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
