Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to an irregularly shaped Rayleigh diffuser panel lamp. Background Technology

[0002] Traditional panel lights mostly use a planar light guide plate structure, with a single, fixed-shape light-emitting surface, making it difficult to meet the needs of personalized scenarios (such as artistic decoration and architectural curved surface lighting). Existing light guide plates rely on dot printing or etching processes to achieve light diffusion, but irregularly shaped structures can easily lead to uneven light output and low luminous efficiency. Therefore, there is an urgent need for a panel light structure that can flexibly design the shape of the light-emitting surface while maintaining high uniformity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an irregularly shaped Rayleigh scattering panel light, which breaks through the limitations of traditional planar structures by providing a customizable light-emitting surface and uniform light effect.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an irregularly shaped Rayleigh scattering panel light, comprising: a light guide plate, an LED light source module, a reflective module, and a light box. The light guide plate is integrally manufactured from a transparent polymer material, and its surface or interior is provided with nano-scale scattering particles. The nano-scale scattering particles have a particle size of 10-500nm and are uniformly arranged or their density decreases from the light source side to the far end. The light-emitting surface of the light guide plate is a non-planar irregularly shaped structure, and its back side is attached to the reflective module with the same curvature. The two ends of the light guide plate and the reflective module are embedded and fixed in the light box. The LED light source module is correspondingly arranged at the point where the light guide plate is embedded in the light box to cooperate with the reflective module in refraction.

[0005] Furthermore, the light-emitting surface of the irregular structure of the light guide plate includes arc shape, stepped shape and wave shape.

[0006] Furthermore, the light guide plates corresponding to the arc-shaped light-emitting surfaces have a uniform thickness, and the light box has grooves formed at both ends of the corresponding arc-shaped structure for the light guide plates to be embedded.

[0007] Furthermore, the LED light source module is distributed along one or more sides of the light guide plate, and its emitted light enters the light guide plate from the side.

[0008] Furthermore, the LED color temperature in the LED light source module is 2700-6500K or 1500-15000K.

[0009] Furthermore, the nanoscale scattering particles uniformly distributed inside the blade plate are nano-titanium dioxide particles with a particle size of 10-500 nm and a concentration of 0.001-1.0 wt%.

[0010] Furthermore, each step of the light guide plate corresponding to the stepped light-emitting surface has the same thickness, and the light box has platforms protruding at both ends of the corresponding stepped structure for the light guide plate to be placed on.

[0011] Furthermore, the LED light source module is located on the side of the top and bottom steps, directly reflecting light in conjunction with the reflective film group.

[0012] Compared with existing technologies, the beneficial effects of this utility model include: by combining an irregularly shaped light guide plate with Rayleigh scattering, it achieves light output from complex curved surfaces with a uniformity of >90%; the overall panel light structure breaks through the limitations of traditional planar designs and can be customized into shapes such as domes and steps to meet diverse scene requirements; it reduces the cost of traditional dot matrix processes, precisely controls the distribution of scattering particles, and improves light efficiency by more than 20%.

[0019] According to one embodiment of the present invention, in conjunction with Figures 1-3 As shown.

[0020] In this embodiment, an irregularly shaped Rayleigh scattering panel light includes: a light guide plate 2, an LED light source module 4, a reflective module, and a light box 1.

The LED light source module 4 is correspondingly arranged at the location where the light guide plate 2 is embedded in the light box 1 to cooperate with the reflective module in refraction.

[0021] The main structural components of a panel light are as follows:

[0022] 1. Irregularly shaped Rayleigh scattering light guide plate 2:

[0023] It is made by injection molding or casting of transparent polymer materials (such as PMMA / PC), with micro- and nano-sized scattering particles set on the surface or inside to simulate the Rayleigh scattering effect;

[0024] The light-emitting surface has an irregular structure (such as a dome, stepped, or wave-shaped), and is not a planar design.

[0025] 2. LED light source module 4:

[0026] The light source is located at at least one edge of the light guide plate 2, and the light source faces the incident surface of the light guide plate 2.

[0027] Optional side-in or direct-in layout, matching the curvature of the irregular light guide plate.

[0028] 3. Reflection module:

[0029] The non-light-emitting surface of the light guide plate 2 is fitted with a high-reflectivity film or a mirrored aluminum layer to reduce light loss.

[0030] The irregularly shaped curved reflective layer is adapted to the contour of the light guide plate 2.

[0031] 4. Lightbox 1:

[0032] The light guide plate 2 and the reflective module are covered, the frame has reserved a light source mounting position, and a light-transmitting cover can be provided on the surface;

[0033] The light-transmitting cover can be either frosted or prism-structured to further optimize the softness of the emitted light.

[0034] The following description uses two examples to illustrate the points.

[0035] Example 1 (Skylight Surface)

[0036] (1) The light guide plate 2 adopts an arc-shaped dome design with uniform thickness;

[0037] (2) The LED light source module 4 is arranged in a ring along the bottom edge, and the light enters the light guide plate 2 through the side entrance;

[0038] (3) The reflective module is attached to the back of the light guide plate 2, and the curvature is consistent with that of the light guide plate 2. Reflective strips are added to the edge to prevent light leakage.

[0039] (4) LED light source color temperature 2700-6500K;

[0040] (5) The Rayleigh scattering light guide plate 2 contains uniformly distributed nano-titanium dioxide particles with a particle size of 20 nm and a concentration of 0.1 wt%.

[0041] (6) When the color temperature of the LED light source is 6500K, due to the Rayleigh scattering effect of the nano titanium dioxide particles, the dome light fixture presents the effect of a blue dome at noon in summer; when the color temperature of the LED light source is 2700K, the dome light fixture presents the effect of a sunset.

[0042] Example 2 (Stepped light-emitting surface)

[0043] (1) The light guide plate 2 has a multi-layer stepped structure, with each step having the same thickness, and the scattering particles are evenly distributed.

[0044] (2) The LED light source module 4 is located on the side of the step, with a direct-down layout and a reflective module for refraction.

[0045] The technical scope of this utility model is not limited to the content described above.
