Description

Technical Field

[0001] This invention relates to the field of lighting technology, specifically to a ceiling light structure that combines color mosaic pixel display with uniform lighting. Background Technology

[0002] To ensure soft, glare-free, and uniform illumination, existing household ceiling lights generally adopt a large-pitch design standard, with a standard spacing of no less than 3 centimeters between the LED beads and the lampshade. Through long-distance air diffuse reflection and light mixing between the beads and the lampshade, the strong light defects of a single point light source are offset, achieving a pure white and uniform lighting effect. The existing technology has the following shortcomings: First, traditional large-pitch uniform light structures can only achieve a single pure white lighting effect, resulting in a monotonous visual effect that cannot create distinctive decorative light and shadow effects such as pixels and mosaics, making it difficult to meet the personalized lighting and shadow decoration needs of modern homes. Second, existing pixel-textured lamps are mostly dedicated ambient lights, with structures adapted for short-term decorative displays, but they cannot serve as daily main lighting functions, resulting in problems such as insufficient illuminance, uneven light, and glare, making them unsuitable for regular home main lighting. Third, there is a fixed technological defect in the industry, with a general belief that the distance between the LED beads and the lampshade needs to be increased to ensure lighting comfort. There is currently no technical solution in this field that can achieve dual compatibility between mosaic pixel light and shadow and daily uniform light lighting by reducing the distance between the LED beads and the lampshade, indicating a significant technological gap. Summary of the Invention

[0003] Purpose of the invention The purpose of this invention is to overcome the shortcomings of the prior art and provide a ceiling light structure that combines color mosaic pixel display and uniform lighting. It breaks through the inherent design defects in the industry and achieves high-definition and regular mosaic pixel texture light and shadow while ensuring the effect of daily main lighting and soft light without glare, by limiting the installation distance between the lamp beads and the lampshade to a very small extent. This solves the industry pain point that traditional lamps have single functions and pixel ambient lights cannot be used as main lighting.

[0004] Technical solution To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a ceiling light structure that combines color mosaic pixel display and uniform lighting, comprising a PCB light board, an array of LED beads, and a diffuser cover fastened to the outside of the PCB light board. The PCB light board is 520mm in size, and 616 groups of LED light sources are evenly arrayed on the PCB light board, with each group of LED light sources configured with 3 LED beads, forming a high-density light source layout; the vertical distance between the emitting surface of the LED beads and the inner surface of the diffuser cover is strictly controlled within the range of 5mm to 10mm. Furthermore, the diffuser cover is made of a high-transmittance soft light diffuser material, which can not only ensure the imaging clarity of the single-point pixel light spot and fully present the mosaic texture effect, but also weaken the strong light of the single point of the LED, eliminate local glare, and achieve uniform integration of the light of the entire lamp.

[0005] Working principle This invention overturns the traditional logic of large-pitch uniform light design. By using an extremely small LED bead-shade spacing of 5mm to 10mm, the light diffusion distance is shortened, allowing each group of LED light sources to form clearly defined colored pixel spots on the diffuser surface. After the 616 groups of light sources are arranged in an array, a large number of independent pixel spots are spliced ​​and merged to form a continuous, orderly, and layered colored mosaic light and shadow effect. At the same time, this invention adopts a high-density LED bead layout, combined with the light diffusion effect of a high-transmittance soft light shade, effectively compensating for the problem of local light concentration caused by small pitch, merging and dispersing pixel light, ensuring uniform light output, sufficient illuminance, and no glare, and stably adapting to indoor daily main lighting scenarios.

[0006] Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. This invention overturns the industry's inherent perception that "only large spacing can achieve soft and uniform light," and uses an extremely small spacing structure to achieve light and shadow control. 2. Compared with traditional solid color ceiling lights, this invention can present high-definition color mosaic pixel decorative light and shadow; compared with conventional pixel ambient lights, this invention has sufficient illumination and soft light, and can be directly used as the main lighting for daily home use, realizing the integration of decoration and lighting functions. 3. This invention does not require complex control circuits or customized light sources. It can achieve exclusive effects simply by optimizing PCB specifications, LED layout, and LED-lens lampshade spacing. The structure is simple and suitable for mass production.

[0008] The present invention will now be described in further detail and in completeness with reference to specific embodiments. This embodiment provides a ceiling light structure that combines color mosaic pixel display with uniform lighting. It uses a 520mm standard PCB board and evenly arrays 616 groups of LED light sources on the surface of the PCB board. Each group of light sources integrates 3 high color rendering LED beads to ensure uniform color and excellent color rendering performance. The diffuser cover is precisely snapped onto the outside of the PCB light board, and the vertical distance between the LED light-emitting surface and the inner surface of the diffuser cover is strictly controlled to be 5mm to 10mm. This distance is the optimal working range, which can ensure that the mosaic pixel texture on the surface of the cover is clear and uniform without blurring or ghosting, and can effectively reduce light glare, thus ensuring indoor lighting comfort. In this embodiment, the diffuser cover is made of high-transmittance PC soft light diffusion material, which has moderate light transmittance and excellent soft light performance. It can accurately present the pixel light spots of a single light source, while achieving uniform fusion of overall light and avoiding uneven brightness in some areas of the lamp. When this lamp is powered on, each group of LED light sources independently forms pixels, and the array is spliced ​​together to form a complete color mosaic light and shadow decoration effect; at the same time, relying on the high-density LED layout and the diffusion effect of the soft light cover, it outputs uniform and soft lighting light, which can be widely adapted to daily home lighting scenarios such as living rooms and bedrooms.
