Description

[Technical Field] This utility model mainly relates to a multi-angle combined linear light guide plate. [Background Technology] As a common type of linear lighting fixture, linear lights are widely used in commercial lighting, home lighting, architectural outlining, shop window displays, and office lighting due to their simple shape, soft light, ease of concealed installation, and ability to create ambiance.

[0003] Currently, mainstream linear lights on the market typically use LEDs as the light source. Their basic structure includes a profile base, an LED light source board, and a diffuser plate or light guide plate covering it. The main purpose of these linear lights is to evenly diffuse the light emitted by the point or line LED light source, creating a continuous, soft, and glare-free lighting effect.

[0004] However, this traditional design concept also brings significant technical drawbacks: it cannot effectively control the direction of light emission, and the diffused light generally follows a Lambertian distribution (i.e., cosine distribution), scattering the light relatively evenly in all directions. In scenarios requiring focused or directional lighting, such as museum exhibit lighting, shopping mall shelf lighting, and office workstation focused lighting, the diffused light of traditional linear lights cannot accurately project light energy onto specific areas, easily leading to unprominent lighting targets and blurred boundaries between ambient light and focused light, failing to meet the needs of advanced lighting design. [Utility Model Content] To solve at least one of the above problems, this utility model proposes a new structural solution. The multi-angle combined linear light guide plate adopts the following technical solution: A multi-angle combined linear light guide plate includes a light guide plate body, wherein the light guide plate body is provided with a direct light lens and a polarizing lens, and the direction of light emitted from the polarizing lens is inclined relative to the direction of light emitted from the direct light lens; the direct light lens and the polarizing lens are disposed on the same end face of the light guide plate body so as to control the emission direction of light simultaneously through the direct light lens and the polarizing lens.

[0006] Preferably, the straight light lens is cup-shaped, and the intersection of the straight light lens and the end face of the lens cavity forms the bottom of the straight light lens. The diameter of the straight light lens gradually decreases from the bottom to the top, and the straight light lens is provided with a first light source port.

[0007] Preferably, the polarizing lens is trapezoidal in shape and has a second light source port.

[0008] Preferably, the light-emitting surface of the direct-beam lens is a flat end face and is horizontally positioned.

[0009] Preferably, the light-emitting surface of the polarizing lens is inclined, and the light-emitting surface of the polarizing lens is composed of several light surfaces.

[0010] Preferably, the light-emitting surface of the polarizing lens includes a first light surface and a second light surface, and the first light surface and the second light surface are inclined to form an angle between them.

[0011] Preferably, the light guide plate has a lens cavity, and both the direct light lens and the polarizing lens are located inside the lens cavity.

[0012] Preferably, the direct-beam lens and the polarizing lens are arranged alternately inside the lens cavity.

[0013] The beneficial effects of this utility model compared with the prior art are: To ensure the directional transmission of light emitted from the light guide plate, this invention proposes a light guide plate structure. The light guide plate is equipped with a direct-light lens and a polarizing lens. The direct-light lens adopts an existing lamp cup structure, and its light-emitting surface is planar, resulting in vertical light rays exiting the lens. The polarizing lens, on the other hand, has a light-emitting surface composed of a first light surface and a second light surface, both of which are inclined and form an angle. Therefore, the light rays passing through the polarizing lens are refracted by the first and second light surfaces and are angled. Through the combined action of the direct-light lens and the polarizing lens, the light guide plate can simultaneously project light in different directions, effectively and accurately projecting light energy onto a specific area, making the illuminated target stand out. It has advantages such as simple structure, compact fit, and reasonable design; therefore, it is a product with superior technical and economic performance.

Detailed Implementation Methods

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] The following description, in conjunction with the accompanying drawings, further illustrates specific embodiments of the present invention, making the technical solution and beneficial effects of the present invention clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The preferred embodiment provided by this utility model is as follows: Figure 1 and Figure 2 As shown, a multi-angle combined linear light guide plate includes a light guide plate body 1. The light guide plate body 1 is provided with a direct light lens 2 and a polarizing lens 3. A lens cavity 11 is provided on the back of the light guide plate body 1. The direct light lens 2 and the polarizing lens 3 are both disposed in the lens cavity 11. The direction of light emitted from the polarizing lens 3 is inclined relative to the direction of light emitted from the direct light lens 2. The direct light lens 2 and the polarizing lens 3 are disposed on the same end face of the light guide plate body 1 so as to simultaneously control the emission direction of light through the direct light lens 2 and the polarizing lens 3.

[0019] The straight light lens 2 is cup-shaped. The intersection of the straight light lens 2 and the end face of the lens cavity 11 forms the bottom of the straight light lens 2. The diameter of the straight light lens 2 gradually decreases from the bottom to the top. The straight light lens 2 is provided with a first light source port 21.

[0020] The polarizing lens 3 is trapezoidal in shape. The polarizing lens 3 is provided with a second light source port 31. The first light source port 21 and the second light source port 31 are both located on one side of the optical cavity of the light guide plate 1.

[0021] The light-emitting surface of the straight-beam lens 2 is a flat and horizontal end face to ensure vertical light emission.

[0022] The light-emitting surface of the polarizing lens 3 is tilted, and the light-emitting surface of the polarizing lens is composed of several light surfaces. When the polarizing lens has only one light-emitting surface, it is also tilted to guide the light to the corresponding tilt angle. When the polarizing lens has two or more light-emitting surfaces, the distance between the two light-emitting surfaces is the same, and the same applies to more than two. When the polarizing lens has two light-emitting surfaces: the light-emitting surface of the polarizing lens 3 includes a first light surface 32 and a second light surface 33, and the first light surface 32 and the second light surface 33 are tilted so that the first light surface 32 and the second light surface 33 form an angle. The light emitted from the second light source port 31 is scattered by the tilted and angled first light surface 32 and the second light surface 33 to form two beams of light in different directions, thereby achieving the purpose of adjusting the illumination angle.

[0023] Straight-beam lenses 2 and polarizing lenses 3 are arranged alternately in the lens cavity 11. Furthermore, a number of straight-beam lenses 2 are arranged as a group, and a number of polarizing lenses 3 are arranged as a group, with a group of straight-beam lenses 2 and a group of polarizing lenses 3 arranged alternately.

[0024] Traditional linear lights simply diffuse the light emitted by the LED light source evenly to create a continuous, soft, and glare-free light output effect. However, they cannot effectively control the direction of light emission. In scenarios requiring focused or directional lighting, such as museum exhibit lighting, shopping mall shelf lighting, and office workstation focused lighting, the diffused light of traditional linear lights cannot accurately project light energy onto specific areas. This can easily lead to the lighting target not being prominent, and the boundary between ambient light and focused light being blurred, failing to meet the needs of high-end lighting design.

[0025] Therefore, this solution develops a light guide plate structure. The lamp plate is installed on the back of the light guide plate, aligning the LED light sources on the lamp plate with the first and second light source ports to emit light through the direct light lens 2 and the polarizing lens 3. The direct light lens 2 adopts the existing lamp cup structure, and the light-emitting surface of the direct light lens is flat, so the light passing through the direct light lens is vertical. The light-emitting surface of the polarizing lens is composed of a first light surface 32 and a second light surface 33, and both the first light surface 32 and the second light surface 33 are inclined and form an angle. Therefore, the light passing through the polarizing lens is inclined under the refraction of the first light surface 32 and the second light surface 33. With the cooperation of the direct light lens and the polarizing lens, the light guide plate can simultaneously form illumination from different directions, effectively and accurately projecting light energy onto a specific area, making the illuminated target stand out.
